Before LOURIE, BRYSON, and MOORE, Circuit Judges.
Opinion for the court filed by Circuit Judge LOURIE. Opinion concurring in part filed by Circuit Judge MOORE. Opinion concurring in part and dissenting in part filed by Circuit Judge BRYSON.
LOURIE, Circuit Judge.
Myriad Genetics, Inc. and the Directors of the University of Utah Research Foundation (collectively, "Myriad") appeal from the decision of the United States District Court for the Southern District of New York holding that an assortment of medical organizations, researchers, genetic counselors, and patients (collectively, "Plaintiffs") have standing under the Declaratory Judgment Act to challenge Myriad's patents. Assoc. for Molecular Pathology v. U.S. Patent & Trademark Office, 669 F.Supp.2d 365 (S.D.N.Y.2009) ("DJ Op."). Myriad also appeals from the district court's decision granting summary judgment that all of the challenged claims are drawn to non-patentable subject matter under 35 U.S.C. § 101. Assoc. for Molecular Pathology v. U.S. Patent & Trademark Office,
On the threshold issue of jurisdiction, we affirm the district court's decision to exercise
Plaintiffs brought suit against Myriad, challenging the patentability of certain composition and method claims relating to human genetics. See DJ Op., at 369-76. Specifically, Plaintiffs sought a declaration that fifteen claims from seven patents assigned to Myriad are drawn to patent-ineligible subject matter under 35 U.S.C. § 101: claims 1, 2, 5, 6, 7, and 20 of U.S. Patent 5,747,282 ("the '282 patent"); claims 1, 6, and 7 of U.S. Patent 5,837,492 ("the '492 patent"); claim 1 of U.S. Patent 5,693,473 ("the '473 patent"); claim 1 of U.S. Patent 5,709,999 ("the '999 patent"); claim 1 of U.S. Patent 5,710,001 ("the '001 patent"); claim 1 of U.S. Patent 5,753,441 ("the '441 patent"); and claims 1 and 2 of U.S. Patent 6,033,857 ("the '857 patent").
The challenged composition claims cover two "isolated" human genes, BRCA1 and BRCA2 (collectively, "BRCA1/2" or "BRCA"), and certain alterations, or mutations, in these genes associated with a predisposition to breast and ovarian cancers. Representative composition claims include claims 1, 2, and 5 of the '282 patent:
SEQ ID NO: 2 depicts the amino acid sequence of the BRCA1 protein, and SEQ ID NO: 1 depicts the nucleotide sequence of the BRCA1 DNA coding region. '282 patent col.19 ll.48-50.
All but one of the challenged method claims cover methods of "analyzing" or "comparing" a patient's BRCA sequence with the normal, or wild-type, sequence to identify the presence of cancer-predisposing mutations. Representative method claims include claim 1 of the '999 and '001 patents:
'999 patent claim 1 (emphases added).
'001 patent claim 1 (emphasis added).
The final method claim challenged by Plaintiffs is directed to a method of screening potential cancer therapeutics. Specifically, claim 20 of the '282 patent reads as follows:
The challenged claims thus relate to isolated gene sequences and diagnostic methods of identifying mutations in these sequences. To place this suit in context, we take a step back to provide background on the science involved, including the identification of the BRCA genes, and the Plaintiffs' connections to the invention and to Myriad.
Human genetics is the study of heredity in human beings.
Chemically, the human genome is composed of deoxyribonucleic acid ("DNA"). Each DNA molecule is made up of repeating units of four nucleotide bases — adenine ("A"), thymine ("T"), cytosine ("C"), and guanine ("G") — which are covalently linked, or bonded,
The linear order of nucleotide bases in a DNA molecule is referred to as its "sequence." The sequence of a gene is thus denoted by a linear sequence of As, Ts, Gs, and Cs. "DNA sequencing" or "gene sequencing" refers to the process by which the precise linear order of nucleotides in a DNA segment or gene is determined. A gene's nucleotide sequence in turn encodes for a linear sequence of amino acids that comprise the protein encoded by the gene, e.g., the BRCA1 gene encodes for the BRCA1 protein. Most genes have both "exon" and "intron" sequences. Exons are DNA segments that are necessary for the creation of a protein, i.e., that code for a protein. Introns are segments of DNA interspersed between the exons that, unlike exons, do not code for a protein.
The creation of a protein from a gene comprises two steps: transcription and translation. First, the gene sequence is "transcribed" into a different nucleic acid called ribonucleic acid ("RNA"). RNA has a chemically different sugar-phosphate backbone than DNA, and it utilizes the nucleotide base uracil ("U") in place of thymine ("T"). For transcription, the DNA double helix is unwound and each nucleotide on the non-coding, or template, DNA strand is used to make a complementary RNA molecule of the coding DNA strand, i.e., adenine on the template DNA strand results in uracil in the RNA molecule, thymine results in adenine, guanine in cytosine, and cytosine in guanine. The resulting "pre-RNA," like the DNA from which it was generated, contains both exon and intron sequences. Next, the introns are physically excised from the pre-RNA molecule, in a process called "splicing," to produce a messenger RNA ("mRNA"). Figure 2 below shows the steps of transcribing a gene that contains three exons (exon 1-3) and two introns (intron 1 and 2) into a pre-RNA, followed by RNA splicing of the introns to produce an mRNA containing just the exon sequences.
Following transcription, the resulting mRNA is "translated" into the encoded protein. Genes, and their corresponding mRNAs, encode proteins via three-nucleotide combinations called codons. Each codon corresponds to one of the twenty amino acids that make up all proteins or a "stop" signal that terminates protein translation. For example, the codon adenine-thymine-guanine (ATG, or UTG in the corresponding mRNA), encodes the amino acid methionine. The relationship between the sixty-four possible codon sequences and their corresponding amino acids is known as the genetic code. Figure 3 below represents an mRNA molecule that translates into a protein of six amino acids (Codon 1, AUG, methionine; Codon 2, ACG, threonine; Codon 3, GAG, glutamic acid; Codon 4, CUU, leucine; Codon 5, CGG, arginine; Codon 6, AGC, serine), and ends with one of the three stop codons, UAG.
Nearly every cell in the human body contains an individual's entire genome. DNA in the cell, called "native" or "genomic" DNA, is packaged into twenty-three pairs of chromosomes. Chromosomes are complex structures of a single DNA molecule wrapped around proteins called histones, as shown in Figure 4 below.
Humans have twenty-two pairs of autosomal chromosomes, numbered one to twenty-two according to size from largest to smallest, and one pair of sex chromosomes, two X chromosomes in females and one X and one Y chromosome in males.
Genomic DNA can be extracted from its cellular environment using a number of well-established laboratory techniques. A particular segment of DNA, such as a gene, can then be excised or amplified from the DNA to obtain the isolated DNA segment of interest. DNA molecules can
Mutations in the BRCA genes correlate with an increased risk of breast and ovarian cancer. The average woman in the United States has around a twelve to thirteen percent risk of developing breast cancer in her lifetime. Women with BRCA mutations, in contrast, face a cumulative risk of between fifty to eighty percent of developing breast cancer and a cumulative risk of ovarian cancer of between twenty to fifty percent. Diagnostic genetic testing for the existence of BRCA mutations is therefore an important consideration in the provision of clinical care for breast or ovarian cancer. This testing provides a patient with information on her risk for hereditary breast and ovarian cancers, and thus aids in the difficult decision regarding whether to undertake preventive options, including prophylactic surgery. Diagnostic results can also be an important factor in structuring an appropriate course of cancer treatment, since certain forms of chemotherapy are more effective in treating cancers related to BRCA mutations.
The inventors of the patents in suit identified the genetic basis of BRCA1 and BRCA2-related cancers using an analysis called positional cloning. Relying on a large set of DNA samples from families with inherited breast and ovarian cancers, the inventors correlated the occurrence of cancer in individual family members with the inheritance of certain marker DNA sequences. This allowed the inventors to identify, or "map," the physical location of the BRCA genes within the human genome and to isolate the BRCA genes and determine their exact nucleotide sequences. This in turn allowed Myriad to provide BRCA diagnostic testing services to women.
Myriad filed the first patent application leading to the patents in suit covering isolated BRCA1 DNA and associated diagnostic methods in August 1994. The first patent, the '473 patent, issued on December 2, 1997. Myriad filed the first application leading to the patents in suit covering isolated BRCA2 DNA and associated diagnostic methods in December 1995, and the first patent, the '492 patent, issued on November 17, 1998.
Myriad, however, was not the only entity to implement clinical BRCA testing services. Starting in 1996, the University of Pennsylvania's Genetic Diagnostic Laboratory ("GDL"), co-directed by plaintiffs Haig H. Kazazian, Jr., M.D. and Arupa Ganguly, Ph.D., provided BRCA1/2 diagnostic services to women. By 1999, however, accusations by Myriad that GDL's BRCA testing services infringed its patents forced the lab to stop providing such services.
The first sign of a dispute came in early 1998. At that time, Dr. Kazazian recalls a dinner with Dr. Mark Skolnick, inventor and Chief Science Office at Myriad. At the dinner, Skolnick informed Kazazian that Myriad was planning to stop GDL from providing clinical BRCA testing in light of Myriad's patents. A month or two later, in May 1998, Kazazian received a letter from William A. Hockett, Director of Corporate Communications at Myriad. The letter stated that Myriad
Months later, in August 1998, Dr. Kazazian received a second letter, this time from George A. Riley of the law firm O'Melveny & Myers LLP. The letter identified by number five Myriad patents "covering, among other things, the BRCA1 gene sequence ... and methods for detecting alternations in the BRCA1 sequence." J.A. 1145. The letter also indicated that it "has come to Myriad's attention that you are engaged in commercial testing activities that infringe Myriad's patents," and that "[u]nless and until a licensing arrangement is completed ... you should cease all infringing testing activity." Id. The letter noted, however, that the cease-and-desist notification did not apply to research testing "for the purpose of furthering non-commercial research programs, the results of which are not provided to the patient and for which no money is received from the patient or the patient's insurance." Id.
In June 1999, Robert Terrell, the General Counsel for University of Pennsylvania, received a similar cease-and-desist letter from Christopher Wight, Myriad's General Counsel. The letter stated, "It has come to our attention that Dr. Haig H. Kazazian, Jr. of the University of Pennsylvania is continuing to willfully engage in commercial BRCA1 and BRCA2 genetic testing activities, in violation of the University of Pennsylvania's previous assurances that such commercial testing activities would be discontinued." J.A. 2890. Terrell responded to Wight by letter on September 10, 1999, stating that "the University agrees that it will not accept samples for BRCA1 research testing from third parties." J.A. 2891. Kazazian thus informed Dr. Ostrer that GDL would no longer be accepting patient samples for BRCA testing from him or anyone else as a result of the patent infringement assertions made by Myriad. As a result, Ostrer started sending patient samples for BRCA genetic testing to Myriad, who became (and remains today) the only provider of such services in the United States.
During this period, Myriad also initiated several patent infringement suits against entities providing clinical BRCA testing. Myriad filed suit against Oncormed Inc. in 1997 and again in 1998, Myriad Genetics v. Oncormed, Nos. 2:97-cv-922, 2:98-cv-35 (D.Utah), and the University of Pennsylvania in 1998, Myriad Genetics v. Univ. of Pa., No. 2:98-cv-829 (D.Utah). Both lawsuits were later dismissed without prejudice after each defendant agreed to discontinue all allegedly infringing activity.
None of the plaintiffs besides Drs. Kazazian, Ganguly, and Ostrer, allege that Myriad directed any letters or other communications regarding its patents at them. Rather, the other researchers and medical organization members state simply that knowledge of Myriad's vigorous enforcement of its patent rights against others stopped them from engaging in clinical BRCA genetic testing, although they have the personnel, expertise, and facilities as well as the desire to provide such testing.
Like the other researchers, Dr. Kazazian states that if Myriad's patents were held invalid, he and Dr. Ganguly would be able to resume BRCA testing within a matter of a few weeks. He notes, however, that this is only if they "decided to resume BRCA testing." J.A. 2852. Ganguly concurs, stating that if the patents were invalidated, "I would immediately consider resuming BRCA testing in my laboratory." J.A. 2892. Ostrer also indicates that his lab has all the personnel, facilities, and expertise necessary to undertake clinical BRCA testing and emphatically states that his lab "would immediately begin to perform BRCA1/2-related genetic testing upon invalidation of the Myriad patents." J.A. 2936-38.
After Plaintiffs filed suit, Myriad moved to have the case dismissed, alleging that the Plaintiffs lacked standing to bring a declaratory judgment suit challenging the validity of its patents. The district court disagreed, however, holding that the Plaintiffs had established Article III standing under the "all the circumstances" test articulated by the Supreme Court in MedImmune, Inc. v. Genentech, Inc.,
In so holding, the court rejected Myriad's argument that there must be some act directed toward the Plaintiffs, noting that Myriad had, in fact, taken affirmative acts toward plaintiffs Dr. Kazazian and Dr. Ganguly. Id. at 387-88. The court also rejected Myriad's arguments that the cease-and-desist letter sent to plaintiff Kazazian was too old to support declaratory judgment jurisdiction and that the legal actions brought against third parties could not be considered in the jurisdictional analysis. Id. at 388-89. The court concluded that rigid adherence to either of these requirements would be inconsistent with MedImmune's mandate that the court assess the facts alleged under all the circumstances. Id.
The district court also found that the Plaintiffs had alleged sufficient meaningful preparations for infringement to establish declaratory judgment jurisdiction. Id. at 390-92. With respect to the researchers, the court held it was sufficient that they were all "ready, willing, and able" to begin BRCA1/2 testing within the normal course of their laboratories' research, rejecting Myriad's argument that they needed to allege specific preparatory activities. Id. at 390-91. The court also rejected Myriad's argument that plaintiffs Kazazian and Ganguly testified only that they would "consider" engaging in allegedly infringing activities, concluding that the proper focus of the inquiry is whether they are meaningfully prepared, not whether they have
The parties then moved for summary judgment on the merits of Plaintiffs' § 101 challenge to Myriad's patent claims. The district court held for Plaintiffs, concluding that the fifteen challenged claims were drawn to non-patentable subject matter and thus invalid under § 101. SJ Op., at 220-37. Regarding the composition claims, the court held that isolated DNA molecules fall within the judicially created "products of nature" exception to § 101 because such isolated DNAs are not "markedly different" from native DNAs. Id. at 222, 232 (quoting Diamond v. Chakrabarty,
Turning to the method claims, the court held them patent ineligible under this court's then definitive machine-or-transformation test. Id. at 233 (citing In re Bilski,
Myriad appealed. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(1).
I. Declaratory Judgment Jurisdiction
The first question we must address is whether the district court correctly exercised declaratory judgment jurisdiction over this suit. The Declaratory Judgment Act provides that, "In a case of actual controversy within its jurisdiction ... any court of the United States ... may declare the rights and other legal relations of any interested party seeking such declaration, whether or not further relief is or could be sought." 28 U.S.C. § 2201(a). The phrase "a case of actual controversy" in the Act refers to the types of "cases" and "controversies" that are justiciable under Article III of the U.S. Constitution. Aetna Life Ins. v. Haworth,
Although no bright-line rule exists for determining whether a declaratory judgment action satisfies Article III's case-or-controversy requirement, the Supreme Court has held that the dispute must be "definite and concrete, touching the legal relations of parties having adverse legal interests," "real and substantial," and "admi[t] of specific relief through a decree
In applying MedImmune's all-the-circumstances test to a declaratory judgment action, we are guided by the Supreme Court's three-part framework for determining whether an action presents a justiciable Article III controversy: standing, ripeness, and mootness. See Caraco Pharm. Labs., Ltd. v. Forest Labs., Inc.,
"[T] he irreducible constitutional minimum of standing contains three elements." Lujan v. Defenders of Wildlife,
"Whether an actual case or controversy exists so that a district court may entertain an action for a declaratory judgment of non-infringement and/or invalidity is governed by Federal Circuit law." MedImmune, Inc. v. Centocor, Inc.,
Myriad challenges the district court's jurisdictional decision on the grounds that Myriad and the Plaintiffs do not have adverse legal interests and that Plaintiffs have failed to allege a controversy of sufficient immediacy and reality to warrant the issuance of a declaratory judgment. Specifically, Myriad argues that Plaintiffs have failed to allege any "affirmative acts" by Myriad within the past ten years relating to the patents in suit or directed at any Plaintiff. According to
Plaintiffs respond that they have standing under MedImmune's all-the-circumstances test because, not only are they undisputedly prepared to immediately undertake potentially infringing activities, but also Myriad took sufficient affirmative acts with respect to the patents in suit. Regarding the latter, Plaintiffs assert that Myriad sued, threatened to sue, or demanded license agreements from every known institution offering BRCA clinical testing, including university labs directed by plaintiffs Kazazian, Ganguly, and Ostrer, forcing each to cease such testing. And, according to Plaintiffs, the awareness of Myriad's vigorous assertion of its patent rights still continues to suppress their ability to perform clinical BRCA testing, placing Plaintiffs in the very dilemma the Declaratory Judgment Act was intended to address: they must either proceed with BRCA-related activities and risk liability for patent infringement, or refrain from such activities despite believing Myriad's patents are invalid.
Under the facts alleged in this case, we conclude that one Plaintiff, Dr. Ostrer, has established standing to maintain this declaratory judgment suit. All Plaintiffs claim standing under the Declaratory Judgment Act based on the same alleged injury: that they cannot undertake the BRCA-related activities that they desire because of Myriad's enforcement of its patent rights covering BRCA1/2.
Although MedImmune relaxed this court's more restrictive "reasonable apprehension of suit" test for declaratory judgment jurisdiction, SanDisk, 480 F.3d at 1380, it did not alter "the bedrock rule that a case or controversy must be based on a real and immediate injury or threat of future injury that is caused by the defendants," Prasco, LLC v. Medicis Pharm. Corp.,
In this case, Myriad demanded a royalty under its patents from Dr. Ostrer based on his clinical BRCA-related activities. In May 1998, Myriad's Director of Corporate Communications sent Ostrer a letter proposing a collaborative license. The letter stated that Myriad was aware that Ostrer was either currently providing, or was interested in initiating, BRCA1 diagnostic testing services and that Myriad, as holder of U.S. patents covering the BRCA1 gene and diagnostic testing of BRCA1, was making available to his institution, NYU Medical Center, a limited collaborative license. The collaborative license required NYU to make a payment to Myriad for each non-research BRCA test performed.
At the same time, as Ostrer was aware, Myriad was asserting its patent rights against other similarly situated parties, a fact to be considered in assessing the existence of an actual controversy under the totality of circumstances. See Micron Tech., Inc. v. Mosaid Techs., Inc.,
Dr. Ostrer, on the other hand, maintains that he could have proceeded with his BRCA-related clinical activities without taking a license from Myriad. This assertion is based on his belief that the patents Myriad claims cover such activities are invalid because genes are patent-ineligible products of nature. Acting on his belief, Ostrer seeks in this lawsuit a declaration of his right to undertake BRCA-related clinical activities without a license. Accordingly, Myriad and Dr. Ostrer have taken adverse legal positions regarding whether or not Ostrer can engage in BRCA genetic testing without infringing any valid claim to "isolated" BRCA DNAs or methods of "analyzing" or "comparing" BRCA sequences, as recited in Myriad's patents. See Aetna Life, 300 U.S. at 242, 57 S.Ct. 461 (holding declaratory judgment jurisdiction existed when "the parties had taken adverse positions with respect to their existing obligations" on an insurance contract).
Dr. Ostrer has also alleged a controversy of sufficient reality and immediacy, MedImmune, 549 U.S. at 127,
Myriad seeks to escape this result based on the timing of its enforcement actions. Specifically, Myriad argues that time has extinguished the immediacy and reality of any controversy, relying on language that hearkens back to our pre-MedImmune reasonable apprehension of suit test. See, e.g., Appellant Br. 26 ("[A] patentee's ten-year silence presumptively extinguishes any reasonable objective fear of suit."). We disagree. In many cases a controversy made manifest by a patentee's affirmative assertion of its patent rights will dissipate as market players and products change. In this case, however, the relevant circumstances surrounding Myriad's assertion of its patent rights have not changed despite the passage of time.
Myriad's active enforcement of its patent rights forced Dr. Ostrer, as well as every other similarly situated researcher and institution, to cease performing the challenged BRCA testing services, leaving Myriad as the sole provider of BRCA clinical testing to patients in the United States. Since that time, neither the accused activities nor the parties' positions have changed. First, Myriad does not allege that genetic testing technology has changed in any way that renders its past assertions of its patent rights irrelevant to Ostrer's currently proposed BRCA testing. Rather, the patents cover, as Myriad asserted in the late 1990s, the basic components of any such test: the isolated BRCA genes and the diagnostic step of comparing the genes' sequences.
Second, ever since Myriad's enforcement efforts eliminated all competition, Myriad and Ostrer have not altered their respective positions. Ostrer, still laboring under Myriad's threat of infringement liability, has not attempted to provide BRCA testing; yet, as a researcher, he remains in the same position with respect to his ability and his desire to provide BRCA testing as in the late 1990s. Furthermore, nothing in the record suggests that any researcher or institution has successfully attempted to compete with Myriad, or that Myriad has in any way changed its position with regard to its patent rights. Just as active enforcement of one's patent rights against others can maintain a real and immediate controversy despite the passage of time, see Micron, 518 F.3d at 901, so too can the successful assertion of such rights when the relevant circumstances remain unchanged. Thus, consistent with the purpose of the Declaratory Judgment Act, Ostrer need not risk liability and treble damages for patent infringement before seeking a declaration of his
Myriad also argues that the record refutes Ostrer's claim that he has been restrained from engaging in BRCA-related gene sequencing. Specifically, Myriad argues that since Myriad published its discoveries of the BRCA1 and BRCA2 genes in October 1994 and March 1996, respectively, over 18,000 scientists have conducted research on the BRCA genes and over 8,600 research papers have been published. Furthermore, according to Myriad, plaintiff Wendy Chung concedes that her lab currently conducts sequencing of BRCA genes. Yet, both Drs. Chung and Ostrer state that, although they conduct gene sequencing, they are forbidden from informing their research subjects of the results of their BRCA tests without first sending the samples to Myriad. Accordingly, Ostrer is restrained from the BRCA-related activity that he desires to undertake: clinical diagnostic testing.
Myriad's communications with Dr. Ostrer confirm this understanding. The licensing letter Myriad sent to Ostrer proposed a collaborative agreement giving NYU the right to perform "Research Tests" without payment to Myriad. J.A. 2967. "Research Tests" are defined as tests that further "non-commercial research programs, the results of which are not provided to the patient and for which no money is received." J.A. 2965 (emphasis added). In contrast, the agreement requires payment to Myriad for each "Testing Service" performed, with "Testing Services" defined as "medical laboratory testing ... for the presence or absence of BRCA1 mutations for the purpose of determining or predicting predisposition to, or assessing the risk of breast or ovarian cancer in humans." J.A. 2966-67. Thus, Myriad's patent enforcement actions never targeted the non-clinical BRCA research now cited by Myriad, and Ostrer's ability to perform such research does not address the injury asserted here.
Finally, Myriad argued in its reply brief and at oral argument that Plaintiffs' declaratory action will not afford them the relief they want, a requirement for standing. Lujan, 504 U.S. at 560-61, 112 S.Ct. 2130; see also MedImmune, 549 U.S. at 127 n. 7,
The Supreme Court has required only that it is "likely," rather than "merely `speculative,'" that the alleged injury will be "redressed by a favorable decision." Lujan, 504 U.S. at 561, 112 S.Ct. 2130. The Court has not required certainty. For example, in Village of Arlington Heights v. Metropolitan Housing Development Corp., the Court held that the plaintiffs had standing to challenge a suburb's exclusionary zoning ordinance, as the ordinance stood as "an absolute barrier" to the housing development Metropolitan Housing Development Corp. ("MHDC") had contracted to provide in the village.
In this case, Myriad's challenged composition and method claims undisputedly provide "an absolute barrier" to Dr. Ostrer's ability to undertake BRCA diagnostic testing activities, and a declaration of those claims' invalidity would remove that barrier. See id. at 261, 97 S.Ct. 555. Moreover, while there may be other patent claims directed to BRCA probes and primers that prevent Ostrer from performing BRCA diagnostic testing free of infringement liability, Myriad has failed to direct us to any specific unchallenged claim that will have that effect. And Plaintiffs' counsel stated at oral argument that his clients can sequence the BRCA genes without using BRCA probes and primers. Oral Arg. at 34:07-25, 34:53-35:29 available at http://www.cafc.uscourts.gov/oral-argument-recordings/2010-1406/all. Accordingly, we decline to construe claims and hold on this record that Dr. Ostrer's proposed BRCA-related activities would infringe unchallenged claims to primers and probes. We thus conclude that it is likely, not merely speculative, that Dr. Ostrer's injury will be redressed by a favorable decision.
Accordingly, although we affirm the district court's decision to exercise declaratory judgment jurisdiction, we affirm on much narrower grounds. The district court failed to limit its jurisdictional holding to affirmative acts by the patentee directed at specific Plaintiffs, see SanDisk, 480 F.3d at 1380-81, erroneously holding all the Plaintiffs had standing based on "the widespread understanding that one may engage in BRCA1/2 testing at the risk of being sued for infringement liability by Myriad," DJ Op., at 390. We disagree, and thus we reverse the district court's holding that the various plaintiffs other than Dr. Ostrer have standing to maintain this declaratory judgment action. Simply disagreeing with the existence of a patent or even suffering an attenuated, nonproximate, effect from the existence of a patent does not meet the Supreme Court's requirement for an adverse legal controversy of sufficient immediacy and reality to warrant the issuance of a declaratory judgment. See MedImmune, 549 U.S. at 127,
Having found one plaintiff with standing to maintain this declaratory judgment action, see Horne v. Flores, ___ U.S. ____,
II. Patentable Subject Matter
Under the Patent Act, "Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title." 35 U.S.C. § 101. The Supreme Court has consistently construed § 101 broadly, explaining that "[i]n choosing such expansive terms ... modified by the comprehensive `any,' Congress plainly contemplated that the patent laws would be given wide scope." Bilski v. Kappos, ___ U.S. ____,
The Supreme Court, however, has also consistently held that § 101, although broad, is not unlimited. Id. The Court's precedents provide three judicially created exceptions to § 101's broad patent-eligibility principles: "laws of nature, physical phenomena, and abstract ideas." Id. (quoting Chakrabarty, 447 U.S. at 309, 100
Plaintiffs challenge under § 101 Myriad's composition claims directed to "isolated" DNA molecules and method claims directed to "analyzing" or "comparing" DNA sequences. We address each in turn.
A. Composition Claims: Isolated DNA Molecules
Myriad argues that its challenged composition claims to "isolated" DNAs cover patent-eligible compositions of matter within the meaning of § 101. According to Myriad, the district court came to a contrary conclusion by (1) misreading Supreme Court precedent as excluding from patent eligibility all "products of nature" unless "markedly different" from naturally occurring ones; and (2) incorrectly focusing not on the differences between isolated and native DNAs, but on one similarity: their informational content. Rather, Myriad argues, an isolated DNA molecule is patent eligible because it is, as claimed, "a nonnaturally occurring composition of matter" with "a distinctive name, character, and use." Appellant Br. 41-42 (quoting Chakrabarty, 447 U.S. at 309-10, 100 S.Ct. 2204). According to Myriad, isolated DNA does not exist in nature, and isolated DNAs, unlike native DNAs, can be used as primers and probes for diagnosing cancer. Moreover, Myriad asserts that a categorical "products of nature" exception not only would be unworkable, as every composition of matter is, at some level, composed of natural materials, but also would be contrary to this court's precedents, the PTO's 2001 Utility Examination Guidelines, and Congress's role in enacting the patent laws.
Plaintiffs respond that claims to isolated DNA molecules fail to satisfy § 101 because such claims cover natural phenomena and products of nature. According to Plaintiffs, Supreme Court precedent establishes that a product of nature is not patent eligible even if, as claimed, it has undergone some highly useful change from its natural form. Rather, Plaintiffs assert, to be patent eligible a composition of matter must also have a distinctive name, character, and use, making it "markedly different" from the natural product. In this case, Plaintiffs conclude that because isolated DNAs retain the same nucleotide sequence as native DNAs, they do not have any "markedly different" characteristics. Furthermore, according to Plaintiffs, the isolated DNA claims also have a preemptive effect, excluding anyone from working with the BRCA genes.
The government as amicus curiae does not defend the PTO's longstanding position that isolated DNA molecules are patent eligible, arguing instead for a middle ground. Specifically, the government argues that DNA molecules engineered by man, including cDNAs,
At oral argument, the government illustrated its argument by way of a "magic microscope" test. Oral Arg. at 46:50-47:50. According to the government's test, if an imaginary microscope could focus in on the claimed DNA molecule as it exists in the human body, the claim covers unpatentable subject matter. The government thus argues that because such a microscope could focus in on the claimed isolated BRCA1 or BRCA2 sequences as they exist in the human body, the claims covering those sequences are not patent eligible. In contrast, the government contends, because an imaginary microscope could not focus in vivo on a cDNA sequence, which is engineered by man to splice together non-contiguous coding sequences (i.e., exons), claims covering cDNAs are patent eligible.
In sum, although the parties and the government appear to agree that isolated DNAs are compositions of matter, they disagree on whether and to what degree such molecules fall within the exception for products of nature. As set forth below, we conclude that the challenged claims to isolated DNAs, whether limited to cDNAs or not, are directed to patent-eligible subject matter under § 101.
The Supreme Court's decisions in Chakrabarty and Funk Brothers set out the framework for deciding the patent eligibility of isolated DNA molecules.
In Chakrabarty, the Court addressed the question whether a man-made, living microorganism is a patentable manufacture or composition of matter within the meaning of § 101. 447 U.S. at 305, 307, 100 S.Ct. 2204. The microorganisms were bacteria genetically engineered with four naturally occurring DNA plasmids, each of which enabled the breakdown of a different component of crude oil. Id. at 305, 305 n. 1, 100 S.Ct. 2204. The bacteria, as a result, could break down multiple components of crude oil, a trait possessed by no single naturally occurring bacterium and of significant use in more efficiently treating oil spills. Id. at 305, 305 n. 2, 100 S.Ct. 2204. The Court held that the bacteria qualified as patentable subject matter because the "claim is not to a hitherto unknown natural phenomenon, but to a nonnaturally occurring manufacture or composition
To underscore the point, the Court compared Chakrabarty's engineered bacteria with bacteria inoculants found unpatentable in Funk Brothers, again casting this case decided on obviousness in terms of § 101. See Parker v. Flook,
The distinction, therefore, between a product of nature and a human-made invention for purposes of § 101 turns on a change in the claimed composition's identity compared with what exists in nature. Specifically, the Supreme Court has drawn a line between compositions that, even if combined or altered in a manner not found in nature, have similar characteristics as in nature, and compositions that human intervention has given "markedly different," or "distinctive," characteristics. Id. Hartranft, 121 U.S. at 615, 7 S.Ct. 1240; see also Am. Fruit Growers v. Brogdex Co.,
It is undisputed that Myriad's claimed isolated DNAs exist in a distinctive chemical form — as distinctive chemical molecules — from DNAs in the human body, i.e., native DNA. Native DNA exists in the body as one of forty-six large, contiguous DNA molecules. Each DNA molecule is itself an integral part of a larger structural complex, a chromosome. In each chromosome, the DNA molecule is packaged around histone proteins into a structure called chromatin, which in turn is packaged into the chromosomal structure. See supra, Figure 3.
Isolated DNA, in contrast, is a free-standing portion of a native DNA molecule, frequently a single gene. Isolated DNA has been cleaved (i.e., had covalent bonds in its backbone chemically severed) or synthesized to consist of just a fraction of a naturally occurring DNA molecule. For example, the BRCA1 gene in its native state resides on chromosome 17, a DNA molecule of around eighty million nucleotides. Similarly, BRCA2 in its native state is located on chromosome 13, a DNA of
As the above description indicates, isolated DNA is not purified DNA. Purification makes pure what was the same material, but was previously impure. Although isolated DNA must be removed from its native cellular and chromosomal environment, it has also been manipulated chemically so as to produce a molecule that is markedly different from that which exists in the body. It has not been purified by being isolated. Accordingly, this is not a situation, as in Parke-Davis & Co. v. H.K. Mulford Co., in which purification of adrenaline resulted in the identical molecule being "for every practical purpose a new thing commercially and therapeutically." 189 F. 95, 103 (C.C.S.D.N.Y.1911). Although, we note, Judge Learned Hand held the claimed purified "Adrenalin" to be patentable subject matter. Id. The In re Marden cases are similarly inapposite,
The dissent disparages the significance of a "chemical bond," presumably meaning a covalent bond, in distinguishing structurally between one molecular species and another. But a covalent bond is the defining boundary between one molecule and another. The dissent's citation of Linus Pauling's comment that covalent bonds
Plaintiffs argue that because the claimed isolated DNAs retain the same nucleotide sequence as native DNAs, they do not have any "markedly different" characteristics. This approach, however, looks not at whether isolated DNAs are markedly different — have a distinctive characteristic — from naturally occurring DNAs, as the Supreme Court has directed, but at one similarity: the information content contained in isolated and native DNAs' nucleotide sequence. Adopting this approach, the district court disparaged the patent eligibility of isolated DNA molecules because their genetic function is to transmit information. We disagree, as it is the distinctive nature of DNA molecules as isolated compositions of matter that determines their patent eligibility rather than their physiological use or benefit. Uses of chemical substances may be relevant to the non-obviousness of these substances or to method claims embodying those uses, but the patent eligibility of an isolated DNA is not negated because it has similar informational properties to a different, more complex natural material that embodies it. The claimed isolated DNA molecules are distinct from their natural existence as portions of larger entities, and their informational content is irrelevant to that fact. We recognize that biologists may think of molecules in terms of their uses, but genes are in fact materials having a chemical nature and, as such, are best described in patents by their structures rather than their functions.
The district court in effect created a categorical rule excluding isolated genes from patent eligibility. See SJ Op., at 228-29. But the Supreme Court has "more than once cautioned that courts `should not read into the patent laws limitations and conditions which the legislature has not expressed,'" Bilski, 130 S.Ct. at 3226 (quoting Diamond v. Diehr,
Because isolated DNAs, not just cDNAs, have a markedly different chemical structure compared to native DNAs, we reject the government's proposed "magic microscope" test, as it misunderstands the difference between science and invention and fails to take into account the existence of molecules as separate chemical entities. The ability to visualize a DNA molecule through a microscope, or by any other means, when it is bonded to other genetic material, is worlds apart from possessing an isolated DNA molecule that is in hand and usable. It is the difference between knowledge of nature and reducing a portion of nature to concrete form, the latter activity being what the patent laws seek to encourage and protect. The government's microscope could focus in on a claimed portion of any complex molecule, rendering that claimed portion patent ineligible, even though that portion never exists as a separate molecule in the body or anywhere else in nature, and may have an entirely different utility. That would discourage innovation. One cannot visualize a portion of a complex molecule, including a DNA containing a particular gene, and will it into isolation as a unique entity. Visualization does not cleave and isolate the particular DNA; that is the act of human invention.
The dissent indicates that we "acknowledge that elemental lithium (like other elements) would not be patentable subject matter because it `is the same element whether it is in earth or isolated.'" Again, these facts are not before us, so we do not attempt to evaluate the patentability of one form of lithium over another. Suffice it to say, however, that if lithium is found in the earth as other than elemental lithium, such as "in molecular form" "because it reacts with air and water," it is not the same material as elemental lithium.
It is also important to dispute the dissent's analogy to snapping a leaf from a tree. With respect, no one could contemplate that snapping a leaf from a tree would be worthy of a patent, whereas isolating genes to provide useful diagnostic tools and medicines is surely what the patent laws are intended to encourage and protect. Snapping a leaf from a tree is a physical separation, not one creating a new chemical entity.
The dissent also mentions several times in its opinion the breadth of certain claims as grounds for objecting to their patentability. However, we do not have here any rejection or invalidation on the various grounds relating to breadth, such as in 35 U.S.C. § 112. The issue before us is patent eligibility, not the adequacy of the patents' disclosure to support particular claims.
Finally, our decision that isolated DNA molecules are patent eligible comports with the longstanding practice of the PTO. The Supreme Court has repeatedly stated that changes to longstanding practice should come from Congress, not the courts. In J.E.M. Ag Supply, Inc. v. Pioneer Hi-Bred International, Inc., the Court rejected the argument that plants did not fall within the scope of § 101, relying in part on the fact that "the PTO has assigned utility patents for plants for at least 16 years and there has been no indication from either Congress or agencies with expertise that such coverage is inconsistent with [federal law]."
In this case, the PTO has issued patents directed to DNA molecules for almost thirty years. In the early 1980s, the Office granted the first human gene patents. See Eric J. Rogers, Can You Patent Genes? Yes and No, 93 J. Pat. & Trademark Off. Soc'y 19 (2010). It is estimated that the PTO has issued 2,645 patents claiming "isolated DNA" over the past twenty-nine years, J.A. 3710, and that by 2005, had granted 40,000 DNA-related patents covering, in non-native form, twenty percent of the genes in the human genome, Rogers, supra at 40. In 2001, the PTO issued Utility Examination Guidelines, which reaffirmed the agency's position that isolated DNA molecules are patent eligible, 66 Fed. Reg. 1092-94 (Jan. 5, 2001), and Congress has not indicated that the PTO's position is inconsistent with § 101. If the law is to be changed, and DNA inventions excluded from the broad scope of § 101 contrary to the settled expectation of the inventing community, the decision must come not from the courts, but from Congress.
II. Method Claims
We turn next to Myriad's challenged method claims. The district court's decision predated the Supreme Court's decision in Bilski, which rejected this court's machine-or-transformation test as the exclusive test for determining whether an invention is a patent-eligible process under § 101, although the test remains "a useful and important clue." 130 S.Ct. at 3227. Both parties, however, had the opportunity to address the Court's decision in briefing and at oral arguments. Accordingly, we proceed to the merits, and we conclude that all but one of Myriad's method claims are directed to patent-ineligible, abstract mental processes, and fail the machine-or-transformation test.
A. Methods of "Comparing" or "Analyzing" Sequences
Myriad argues that its claims to methods of "comparing" or "analyzing" BRCA sequences satisfy the machine-or-transformation test as applied by this court in Prometheus because each requires a transformation — extracting and sequencing DNA molecules from a human sample — before the sequences can be compared or analyzed. According to Myriad, the district court failed to recognize the transformative nature of the claims by (1) misconstruing the claim term "sequence" as just information, rather than a physical molecule; and (2) erroneously concluding, in the alternative, that Myriad's proposed transformations were mere data-gathering steps, rather than central to the purpose of the claims.
Plaintiffs respond that these method claims are drawn to the abstract idea of comparing one sequence to a reference sequence and preempt a phenomenon of nature — the correlation of genetic mutations with a predisposition to cancer. And, according to the Plaintiffs, limiting the claims' application to a specific technological field, i.e., BRCA gene sequences, is insufficient to render the claims patent eligible. Plaintiffs also assert that the claims do not meet the machine-or-transformation test because the claims' plain language includes just the one step of "comparing" or "analyzing" two gene sequences.
We conclude that Myriad's claims to "comparing" or "analyzing" two gene sequences fall outside the scope of § 101 because they claim only abstract mental processes. See Benson, 409 U.S. at 67, 93 S.Ct. 253 ("Phenomena of nature, ... mental processes, and abstract intellectual concepts
Limiting the comparison to just the BRCA genes or, as in the case of claim 1 of the '999 patent, to just the identification of particular alterations, fails to render the claimed process patent eligible. As the Supreme Court has held, "the prohibition against patenting abstract ideas `cannot be circumvented by attempting to limit the use of the formula to a particular technological environment.'" Bilski, 130 S.Ct. at 3230 (quoting Diehr, 450 U.S. at 191-92, 101 S.Ct. 1048); see also id. at 3231 ("Flook established that limiting an abstract idea to one field of use ... did not make the concept patentable."). Although the application of a formula or abstract idea in a process may describe patentable subject matter, id. at 3230, Myriad's claims do not apply the step of comparing two nucleotide sequences in a process. Rather, the step of comparing two DNA sequences is the entire process claimed.
To escape this result, Myriad attempts to read into its method claims additional, transformative steps. As described above, Myriad reads into its claims the steps of (1) extracting DNA from a human sample, and (2) sequencing the BRCA DNA molecule, arguing that both steps necessarily precede the step of comparing nucleotide sequences. The claims themselves, however, do not include either of these steps. The claims do not specify any action prior to the step of "comparing" or "analyzing" two sequences; the claims recite just the one step of "comparing" or "analyzing." Moreover, those terms' plain meaning does not include Myriad's proposed sample-processing steps; neither comparing nor analyzing means or implies "extracting" or "sequencing" DNA or otherwise "processing" a human sample.
Myriad claims that "comparing" and "analyzing" take on this meaning when read in light of the patent specifications. Specifically, Myriad argues that the specifications show that the claim term "sequence" refers not to information, but rather to a physical DNA molecule, whose sequence must be determined before it can be compared. We disagree. The patent specifications make clear that "sequence" does not exclusively specify a DNA molecule, but refers more broadly to the linear sequence of nucleotide bases of a DNA molecule. For example, Figure 10A-10H is described as showing the "genomic sequence of BRCA1." '473 patent col.5 l.66. Figure 10 does not show a physical DNA molecule; the figure lists a series of letters (Gs, As, Ts, and Cs) corresponding to the nucleotides guanine, adenine, thymine, and cytosine of a DNA molecule. Similarly, the patent specifications state that "[t]he nucleotide sequence for BRCA1 exon 4 is shown in SEQ ID NO: 11." Id. col.53 ll.50-53. SEQ ID NO: 11 again lists a series of Gs, As, Ts, and Cs corresponding to the nucleotide sequence of BRCA1 exon 4.
Myriad's claims, in contrast, do not include the step of "determining" the sequence of BRCA genes by, e.g., isolating the genes from a blood sample and sequencing them, or any other necessarily transformative step. Rather, the comparison between the two sequences can be accomplished by mere inspection alone. Accordingly, Myriad's claimed methods of comparing or analyzing nucleotide sequences fail to satisfy the machine-or-transformation test, and are instead directed to the abstract mental process of comparing two nucleotide sequences. The claims thus fail to claim a patent-eligible process under § 101.
B. Method of Screening Potential Cancer Therapeutics
Lastly, we turn to Myriad's method claim directed to a method for screening potential cancer therapeutics via changes in cell growth rates. '282 patent claim 20. Plaintiffs challenge this claim as directed to the abstract idea of comparing the growth rates of two cell populations and as preempting a basic scientific principle — that a slower growth rate in the presence of a potential therapeutic compound suggests that the compound is a cancer therapeutic. We disagree.
Starting with the machine-or-transformation test, we conclude that the claim includes transformative steps, an "important clue" that it is drawn to a patent-eligible process. Bilski, 130 S.Ct. at 3227. Specifically, the claim recites a method that comprises the steps of (1) "growing" host cells transformed with an altered BRCA1 gene in the presence or absence of a potential cancer therapeutic, (2) "determining" the growth rate of the host cells with or without the potential therapeutic, and (3) "comparing" the growth rate of the host cells. The claim thus includes more than the abstract mental step of looking at two numbers and "comparing" two host cells' growth rates. The claim includes the steps of "growing" transformed cells in the presence or absence of a potential cancer therapeutic, an inherently transformative step involving the manipulation of the cells and their growth medium. The claim also includes the step of "determining" the cells' growth rates, a step that also necessarily involves physical manipulation of the cells. Furthermore, these steps are central to the purpose of the claimed process. See Prometheus, 628 F.3d at 1356-57, 1358 (quoting In re Bilski, 545 F.3d at 962).
Furthermore, the claim is not so "manifestly abstract" as to claim only a scientific principle, and not a patent-eligible process. See Research Corp. Techs., Inc. v. Microsoft Corp.,
For the foregoing reasons, we affirm the district court's decision to exercise declaratory judgment jurisdiction over this case, we reverse the district court's grant of summary judgment with regard to Myriad's composition claims to isolated DNAs, we affirm the district court's grant of summary judgment with regard to Myriad's method claims to comparing or analyzing gene sequences, and we reverse the district court's grant of summary judgment with regard to Myriad's method claim to screening potential cancer therapeutics via changes in cell growth rates.
MOORE, Circuit Judge, concurring-in-part.
I join the majority opinion with respect to standing and the patentability of the method claims at issue. I believe, however, that claims directed to isolated DNA sequences present a different set of issues. I join the majority with respect to claims to isolated cDNA sequences, and concur in the judgment with respect to the remaining sequences. I write separately to explain my reasoning.
The Patent Act, 35 U.S.C. § 101, allows "[w]hoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof" to obtain a patent. The plain language of this statute only requires that an invention be "new and useful," and fall into one of four categories: a "process, machine, manufacture, or composition of matter." Congress did not impose any additional constraints on the scope of patentable subject matter. In fact, "Congress intended statutory subject matter to `include anything under the sun that is made by man.'" Diamond v. Chakrabarty,
While the plain language used by Congress did not limit the scope of patentable subject matter in the statute, the "Court's precedents provide three specific exceptions to § 101's broad patent-eligibility principles: `laws of nature, physical phenomena, and abstract ideas.'" Bilski v. Kappos, ___ U.S. ____,
Applying the judicially created exception to the otherwise broad demarcation of statutory subject matter in section 101 can be difficult. See Funk Bros. Seed Co. v. Kalo Inoculant Co.,
Even though an invention did not previously exist in nature in exactly the claimed state, however, does not automatically mean it is patentable subject matter. For example, in Funk Brothers, the Supreme Court held a patent to a combination of multiple naturally occurring bacterial strains was not patentable. Although there was "an advantage in the combination," which was apparently "new and useful," none of the bacterial strains "acquire[ed] a different use" in combination. Id. at 131-32, 68 S.Ct. 440. The aggregation of the bacterial strains into a single product produced "no new bacteria, no change in the six species of bacteria, and no enlargement of the range of their utility. Each species has the same effect it always had. The bacteria perform in their natural way.... They serve the ends nature originally provided and act quite independently of any effort of the patentee." Id.
In contrast, the Supreme Court held bacteria that included extra genetic material introduced by the inventor were "a nonnaturally occurring manufacture or composition of matter — a product of human ingenuity `having a distinctive name, character [and] use'" and therefore patentable. Chakrabarty, 447 U.S. at 309-310, 100 S.Ct. 2204 (quoting Hartranft v. Wiegmann,
Funk Brothers and Chakrabarty do not stake out the exact bounds of patentable subject matter. Instead, each applies a flexible test to the specific question presented in order to determine whether the claimed invention falls within one of the judicial exceptions to patentability. Funk Brothers indicates that an invention which "serve[s] the ends nature originally provided" is likely unpatentable subject matter, but an invention that is an "enlargement of
Courts applied an analogous patentability inquiry long before Funk Brothers or Chakrabarty. In one notable case, Judge Learned Hand held that purified adrenaline, a natural product, was patentable subject matter. Judge Hand explained that even if the claimed purified adrenaline were "merely an extracted product without change, there is no rule that such products are not patentable." Parke-Davis & Co. v. H.K. Mulford Co., 189 F. 95, 103 (S.D.N.Y.1911). This is because "while it is of course possible logically to call this a purification of the principle" the resulting purified adrenaline was "for every practical purpose a new thing commercially and therapeutically." Id. Similarly, in a case applying the Patent Act of 1952,
In contrast, mere purification of a naturally occurring element is typically insufficient to make it patentable subject matter. For example, our predecessor court held that claims to purified vanadium and purified uranium were not patentable subject matter since these were naturally occurring elements with inherent physical properties unchanged upon purification. See In re Marden, 18 CCPA 1057,
As illustrated by these examples, courts have long applied the principles articulated
The majority conducts a thoughtful analysis of the scientific principles associated with the claims at issue in this case. I write separately here to emphasize certain chemical considerations which I believe are particularly important in this case.
DNA is a chemical polymer. In principle, a polymeric DNA sequence is no different than any other well known polymer, for example, nylon. Like any polymer, DNA is made up of repeating monomer units, connected by chemical bonds to form one larger molecule. In a DNA sequence, the letters A, C, T, and G each represent a different monomer unit; each monomer has a distinct structure, with distinct properties. When they are assembled into a DNA sequence, these monomers are chemically bonded to each other. The process of polymerization of the monomer units — whether carried out by chemical or biological means — results in a new molecule. For example, the sequence A-T-C-G-T represents a single molecule created by polymerizing five monomer units: A, T, C, G, and T again. As illustrated by the figure below, polymerization changes the monomers and results in a molecule with a different ionic charge, different chemical bonds, and a different chemical composition, as compared to the monomers in aggregate.
A-T-C-G-T polymer (left) versus the A, T, C, G, T aggregated monomers (right)
Deconstructing an existing DNA sequence leads to similar results: a fragment of a DNA sequence has different properties than the parent molecule from which it is derived. For example, as shown below, a two nucleotide sequence (T-C), has a different chemical structure, and different chemical connections than the same subunit found within the larger A-T-C-G-T structure. Despite many similarities, it is impossible to find the isolated T-C structure in the A-T-C-G-T molecule. This is because, instead of being connected to a phosphate, the C subunit terminates in a different functional group, a hydroxyl. Likewise, instead of being connected to another sugar via a phosphodiester bond, the T subunit instead terminates in a phosphate. The isolated T-C sequence is a different molecule than the "T-C" sequence appearing as part of the larger A-T-C-G-T polymer. These changes are indicated with arrows below.
A-T-C-G-T polymer (left, with T-C highlighted) versus "isolated" T-C molecule (right)
The isolated DNA sequences at issue in this case have the same type of chemical changes, but on a much bigger scale. Instead of a string of five nucleotides, the chromosome is millions of base pairs; instead of a two-monomer molecule, the isolated molecules claimed in this case range from 15 nucleotides to thousands (or tens of thousands) of nucleotides. Nevertheless, like the simple sequences discussed above, just because the same series of letters appears in both the chromosome and an isolated DNA sequence does not mean they are the same molecule. While the isolated DNA molecules claimed in this case are undoubtedly inspired by the corresponding naturally occurring sequence present on the chromosome, man must create these isolated DNA molecules.
Isolation of a DNA sequence is more than separating out impurities: the isolated DNA is a distinct molecule with different physical characteristics than the naturally occurring polymer containing the corresponding sequence in nature. These differences, of course, are directly related to the change in chemical bonds in the isolated DNA. Instead of being connected to many thousands of additional nucleotides at the 3' and 5' ends of the sequence in question, as is the case in the chromosome, the isolated DNA molecules terminate in, for example, a hydroxyl and a phosphate group, respectively.
There are other differences between an isolated DNA sequence and that same DNA sequence as part of the chromosome. The DNA sequence of a gene, as it occurs in nature, is part of a much larger structure, the chromosome. The claims in suit include DNA sequences as short as fifteen nucleotides, and the isolated BRCA1 cDNA sequence has approximately six thousand nucleotides (see, e.g., '282 col.67-80 (SEQ ID NO: 1)). Both of these are much smaller than the isolated full length BRCA1 gene sequence, which, as discussed below, includes both exon and intron sequences. Even the isolated BRCA1 gene, however, is substantially smaller than chromosome 17, which includes the unisolated BRCA1 gene as well as many other genes. J.A. 4321. Isolation of a DNA sequence thus results in a substantially smaller molecule compared to the naturally occurring sequence as part of the chromosome.
cDNA, unlike isolated or unisolated DNA, has a unique sequence of DNA bases (A, C, G, T) which is not actually present in nature. While cDNA is derived from RNA, it has a distinctly different sequence of nucleotides, substituting in the complementary nucleotide (swapping G and C, and A and T/U) to form a DNA sequence that is completely different than the corresponding RNA. There is no contiguous sequence on the chromosome that duplicates the cDNA sequence. Moreover, the naturally occurring gene sequence includes both introns (which are removed) and exons (which are included in the mature RNA). The cDNA sequences, which are complementary to the mature RNA, do not include the introns.
Schematic illustrating RNA splicing (J.A. 4331)
Creating isolated DNA allows a scientist, among other things, to remove potentially confounding sequences that are naturally present in the larger chromosomal polymer, and instead focus on just the sequence of interest. This aspect of isolated DNA has important practical consequences and leads to additional utility, particularly for the smaller isolated fragments. For example, a small fragment of isolated DNA can be used as a primer in order to selectively detect the presence of the BRCA1 gene or BRCA1 gene mutation in a patient. Armed with this scientific background, we can now apply the
The isolated DNA claims of the patents in suit fall into two categories. The first category of claims is directed to isolated sequences that are identical to naturally occurring gene sequences. These include claims encompassing both the isolated full length gene sequence (e.g. claim 1 of '282 patent), which are thousands of nucleotides, and claims to shorter isolated DNA strands, with as few as fifteen nucleotides, whose nucleotide sequence is found on the chromosome (e.g. claim 5 of '282 patent). The second category of claims is directed to isolated DNA sequences that are different from the naturally occurring gene sequences. These include claims to isolated cDNA molecules (e.g. claim 2 of the '282 patent), which differ from the natural gene sequence in that the introns are removed, and are the opposite (complementary) sequence of the naturally occurring RNA.
The cDNA claims present the easiest analysis. Although the plaintiffs (now plaintiff) in the suit argue, and the district court held, that cDNA falls within the "laws of nature" exception to section 101 patentability, I cannot reconcile this argument with the fact that the claimed cDNA sequences do not exist in nature. Moreover, since cDNA has all of the introns removed, and only contains the coding nucleotides, it can be used to express a protein in a cell which does not normally produce it. Of course, the claimed isolated cDNA is inspired by nature — after all, naturally occurring RNA is the template upon which cDNA is constructed. Because it is used as a template, however, cDNA has a complementary sequence of nucleotides, and therefore has a completely different nucleotide sequence than the RNA. Moreover, DNA has a different chemical structure than RNA, including a different base (T instead of U, respectively) and sugar units (deoxyribose instead of ribose, respectively). This results in, among other things, greater stability for the DNA sequence as compared to the RNA sequence.
cDNA sequences thus have a distinctive name, character, and use, with markedly different chemical characteristics from either the naturally occurring RNA or any continuous DNA sequence found on the chromosome. The claimed isolated cDNA sequences are the creation of man, made using biological tools and the naturally occurring mRNA as a template. cDNA is therefore not one of the "`manifestations of ... nature, free to all men and reserved exclusively to none'" that falls outside of the patent system. Chakrabarty, 447 U.S. at 309, 100 S.Ct. 2204 (quoting Funk Bros., 333 U.S. at 130, 68 S.Ct. 440). I decline to extend the laws of nature exception to reach entirely manmade sequences of isolated DNA, even if those sequences are inspired by a natural template. I therefore join the majority opinion with respect to the claims to cDNA sequences.
DNA sequences that have the same pattern of DNA bases as a natural gene, in whole or in part, present a more difficult issue. Unlike the isolated cDNA molecules, whose sequence is not present in nature, these kinds of isolated DNA claims include nucleotide sequences which are found in the human body, albeit as part of a much larger molecule, the chromosome. The majority analysis focuses on the "markedly different chemical structure" of isolated DNAs, as compared to the corresponding native DNA. Majority at 1353. Although the different chemical structure
Given the chemical differences highlighted by Judge Lourie's opinion and discussed supra, the mere fact that the larger chromosomal polymer includes the same sequence of nucleotides as the smaller isolated DNA is not enough to make it per se a law of nature and remove it from the scope of patentable subject matter. The actual molecules claimed in this case are therefore not squarely analogous to unpatentable minerals, created by nature without the assistance of man. Instead, the claimed isolated DNA molecules, which are truncations (with different ends) of the naturally occurring DNA found as part of the chromosome in nature, are not naturally produced without the intervention of man. Cf. Chakrabarty, 447 U.S. at 312-13, 100 S.Ct. 2204.
Given the differences, we should, as precedent instructs, consider whether these differences impart a new utility which makes the molecules markedly different from nature. I begin with the short isolated sequences such as those covered by claim 5 which is directed to "an isolated DNA having at least 15 nucleotides of the DNA of claim 1." This claim covers a sequence as short as 15 nucleotides and arguably as long as the entire gene. For this claim to be patent eligible, all of the sequences ranging from the 15 nucleotide sequence to the full gene must be patentable subject matter. The shorter isolated DNA sequences have a variety of applications and uses in isolation that are new and distinct as compared to the sequence as it occurs in nature. For example, these sequences can be used as primers in a diagnostic screening process to detect gene mutations. These smaller isolated DNA sequences — including isolated radiolabeled sequences mirroring those on the chromosome — can also be used as the basis for probes. Naturally occurring DNA cannot be used to accomplish these same goals. Unlike the isolated DNA, naturally occurring DNA simply does not have the requisite chemical and physical properties needed to perform these functions.
The ability to use isolated DNA molecules as the basis for diagnostic genetic testing is clearly an "enlargement of the range of ... utility" as compared to nature. Funk Bros., 333 U.S. at 131, 68 S.Ct. 440. Indeed, many of the plaintiffs in this case submitted declarations indicating that they wanted to either offer such testing or receive such testing. These new applications, of course, rely on physical properties devised by nature, namely the ability of a strand of DNA to specifically interact with a complementary strand. Diagnostic testing, however, is not a natural utility — the body does not naturally engage in this type of testing, and certainly does not do so with the shorter (non-naturally occurring) isolated DNA used by man. As such, the claimed DNA does not "serve the ends nature originally provided." Id. Instead, the isolated DNA sequences have markedly different properties which are directly responsible for their new and significant utility. Chakrabarty, 447 U.S. at 309-10, 100 S.Ct. 2204. The same sequence, as it appears in nature as part of the chromosome, simply cannot be used in the same way. Because the different chemical structure of the isolated DNA, which is a product of the intervention of man, leads to a different and beneficial utility, I believe small, isolated DNA fragments are patentable subject matter.
Longer strands of isolated DNA, in particular isolated strands which include most or all of the entire gene, are a much closer case. Some of the claims at issue, for example '282 patent claim 5, are genus claims, drafted broadly enough to include both short fragments as well as the entire isolated gene sequence. As discussed above, I believe many species within this genus — the shorter isolated DNA fragments — are clearly patentable subject matter based on their new structure and corresponding enlarged range of utility. Yet that still leaves species that include most or all of the isolated gene sequence. While I ultimately conclude that these longer isolated sequences, including the isolated gene sequence as a whole, are also patentable subject matter, I do so for a reason different than for the shorter sequences.
All of the same structural arguments apply to any length of isolated DNA so, like the shorter strands, an isolated DNA coding for a gene does have a literal chemical difference from the gene as it appears on the chromosome. Different ends in a 15 nucleotide sequence have greater significance than different ends in a 6000 nucleotide sequence. Unlike the shorter strands of isolated DNA, the chemical and structural differences in the isolated gene do not clearly lead to an "enlargement of the range of ... utility" as compared to nature. Funk Bros., 333 U.S. at 131, 68 S.Ct. 440. For example, the full length gene is too large to be used as a probe. See J.A. 4322 (a probe is a DNA molecule usually 100-1,000 bases long). Likewise, an entire isolated gene appears unsuitable for use as a primer in genetic screening for mutations in that same gene. See J.A. 4323 (Primers "are complementary to an exact location of a much larger target DNA molecule." (emphasis added)). As such, the chemical and structural differences in an isolated DNA sequence which includes most or all of a gene do not clearly lead to significant new utility as compared to nature. Whether an isolated gene is patentable subject matter depends on how much weight is allocated to the different structure as compared to the similarity of the function to nature.
If I were deciding this case on a blank canvas, I might conclude that an isolated DNA sequence that includes most or all of a gene is not patentable subject matter.
For more than a decade the Patent Office's policy has been that "[a]n isolated and purified DNA molecule that has the same sequence as a naturally occurring gene is eligible for a patent because ... that DNA molecule does not occur in that isolated form in nature...." 66 Fed.Reg. 1092, 1093 (Jan. 5, 2001). The explicit statement of the Patent Office's position on isolated DNA, however, is simply a continuation of a longstanding and consistent policy of allowing patents for isolated natural products. See id. (noting U.S. Patent 141,072, claiming "[y]east, free from organic germs of disease," issued to Louis Pasteur in 1873); cf. In re Bergstrom, 57 CCPA 1240,
Even before the current guidelines formalized the Patent Office's position, however, it granted patents to human genes in the early 1980s, and subsequently issued thousands of patents on "isolated DNA." Majority at 1354-55. In fact, claims similar to the ones at issue in this case have been the focal point of important litigation. For example, Amgen, Inc. v. Chugai Pharmaceutical Co.,
The settled expectations of the biotechnology industry — not to mention the thousands of issued patents — cannot be taken lightly and deserve deference. This outpouring of scientific creativity, spurred by the patent system, reflects a substantial investment of time and money by the biotechnology industry to obtain property rights related to DNA sequences. The type of fundamental alteration in the scope of patentable subject matter argued in this case "risk[s] destroying the legitimate expectations of inventors in their property." Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co.,
The Supreme Court has warned that "courts must be cautious before adopting changes that disrupt the settled expectations of the inventing community." Festo, 535 U.S. at 739, 122 S.Ct. 1831. The settled expectations of the inventing community with respect to isolated DNA claims are built upon the broad language of the statute, judicial precedent, such as Parke-Davis and Merck, and the Patent Office's longstanding policy and practice. Neither Funk Brothers nor Chakrabarty purported to overrule either the early cases or the Patent Office's practice; indeed, as discussed supra, these cases weigh the same considerations as Parke-Davis and Merck. "`To change so substantially the rules of the game now,'" after more than a century of practice, "`could very well subvert the various balances the PTO sought to strike when issuing the numerous patents which have not yet expired and which would be affected by our decision.'" Festo, 535 U.S. at 739, 122 S.Ct. 1831 (quoting Warner-Jenkinson Co. v. Hilton Davis Chem. Co.,
Although the Patent Office has consistently followed the same policy for a decade (and arguably a century or more), the United States, as an amicus represented at argument by the Solicitor General, now argues that the Patent Office's published guidelines are incorrect and a misstatement of the law. In place of these guidelines, the Solicitor General suggested that we should use a "magic microscope" as part of our section 101 analysis. If we could observe the claimed substance in nature using this microscope, the Solicitor General argues, it is not patentable. The magic microscope test applies equally to portions of a larger, naturally occurring molecule. For example, the optical field of view could be zoomed to see just a sequence of fifteen nucleotides within the chromosome. As long as you could "see" the claimed molecule in nature using the magic microscope, it would fall into the "laws of nature" exception and be unpatentable subject matter.
Certainly the magic microscope has curb appeal — its child-like simplicity an apparent virtue. The magic microscope, however, would not see the claimed DNA molecules at issue in this case. An isolated DNA molecule has different chemical bonds as compared to the "unisolated" sequence in the chromosome (the ends are different). In short, the claimed molecules cannot be seen in nature through the magic microscope. While you may be able to see the order of DNA nucleotides in the chromosome, the isolated fragment of
While the magic microscope creates a bright line rule, it presents a poorly defined question: can we "see" the claimed molecule, or something fairly similar, in nature? Even if the scientific imprecision of the test were excusable, the government also asks us to do away with Chakrabarty's flexible inquiry as to whether the invention, as claimed, has "markedly different characteristics from any found in nature" which result in "the potential for significant utility." Id. at 310, 100 S.Ct. 2204. Indeed, the bright line magic microscope test actually appears to be contrary to Funk Brothers, since the combination of bacteria in that case was a "new and different composition of non-inhibitive strains," 333 U.S. at 130-31, 68 S.Ct. 440, and therefore not actually present in nature. There may be additional nuance in the government's argument that accounts for this inconsistency, but under my understanding of the magic microscope test, the combination in Funk Brothers would be patentable subject matter.
Indeed, the government does not apply its own understanding of section 101 consistently. In its brief, the United States explains that "[a] chemical alteration of a bioactive molecule to improve absorption by the body ... would likely satisfy section 101." United States Amicus Br. 31 n. 8. As discussed supra, the isolated DNA molecules at issue in this case are the result of a "chemical alteration of a bioactive molecule" that leads to different properties, including a dramatic reduction in size. Just as the government's theoretical "chemical alteration" leads to a molecule with improved absorption properties, the isolation of discrete DNA sequences changes the properties of the sequence as compared to the chromosomal DNA. This is not "[m]erely sorting the proverbial wheat from the chaff," id., but the creation of new DNA molecules with distinct properties and additional utility, including the ability to be used as a primer in genetic testing.
The government's new test fundamentally changes more than a century of precedent and Patent Office practice in the pharmaceutical and biotechnology arena. The proposed test is a purely mechanical inquiry that fails to account for the possibility that chemical changes to the isolated DNA sequences at issue, as compared to their natural state, could result in markedly different uses. As such, the government's position in this case calls into question the validity of an unknown number of patents and claims and upsets the settled expectations of some of our most innovative industries. This is not a "very limited position."
The dissent claims that the Patent Office's past views are "substantially undermined by the position the government has taken in this case." Dissent at 1380. The Patent Office's prior practice, however, is particularly important since it resulted in a large number of property rights over the past decades. If the Executive decided to change course in the Patent Office, and decline to issue new patents to isolated genes, it would not impact these existing property rights. This, however, is not what the Executive argues in this case. Instead the Solicitor General argues for an entirely different interpretation of the law that would destroy existing property rights. Although the dissent points out that Chakrabarty overturned the Patent Office's practice of denying patents to microorganisms, there is a clear difference between allowing additional patent protection where none previously existed, and denying patent protection decades (or centuries) after the fact, thereby eliminating a large number of property rights. Moreover, Chakrabarty, consistent with the broad language of the statute, allowed additional patents where none previously existed. Here, the Solicitor General proposes to destroy existing property rights based on a judge made exception to that same broad language. This is a dramatic step that I believe is best left to the legislature.
Nevertheless, the Solicitor General claims that "this is a pure question of law" and that we can therefore feel free to ignore the years of Patent Office practice and the accompanying expectations that practice created within the industry. The Solicitor General argues that we should not defer to the broad language (all but unchanged since 1793) provided by Congress in the patent statute, or allow Congress
The Solicitor General's invitation is tempting, but I must decline the opportunity to act where Congress remains silent. "[O]ur obligation is to take statutes as we find them...." Chakrabarty, 447 U.S. at 315, 100 S.Ct. 2204. With respect to section 101, "[t]he subject-matter provisions of the patent law have been cast in broad terms to fulfill the constitutional and statutory goal of promoting `the Progress of Science and the useful Arts'...." Id. Any judicial exception to the statute's broad language must be applied with care lest the courts usurp Congress's constitutionally mandated authority to promote science and useful arts. Judicial restraint is particularly important here because an entire industry developed in the decades since the Patent Office first granted patents to isolated DNA. Disturbing the biotechnology industry's settled expectations now risks impeding, not promoting, innovation.
Regardless, the judiciary is ill-suited to determine whether the claims at issue promote or inhibit science and useful arts in all but the clearest cases, for example a new mineral discovered in the earth, or a new plant found in the wild, or E=mc
The dissent suggests that "this may well be one of those instances in which `too much patent protection can impede rather than "promote the Progress of Science and useful Arts."'" Dissent at 1380 (quoting Lab. Corp. of Am. Holdings v. Metabolite Labs., Inc.,
In fact, Congress has at least implicitly approved of the Patent Office's policy of awarding patents on genes and DNA sequences. For example, Congress included, as part of the Patent Office's appropriations, language affirming the Patent Office's interpretation of section 101 to prohibit patents on human organisms. Consolidated Appropriations Act, 2004, Pub.L. No. 108-199, § 634, 118 Stat. 3, 101. Although Congress was aware "that there are many institutions ... that have extensive patents on human genes," 149 Cong. Rec. H7248, H7274, it explicitly declined to implement legislation to "affect any of those current existing patents." Id. (statement of Mr. Weldon introducing amendment). To the contrary, it made clear that the language related to "human organisms" was not intended to change the Patent Office's policy with respect to claims to genes, stem cells, or other similar inventions. Id.
This case typifies an observation by the late Chief Judge Markey, our first Chief Judge, that "[o]nly God works from nothing. Men must work with old elements." Fromson v. Advance Offset Plate, Inc.,
BRYSON, Circuit Judge, concurring in part and dissenting in part:
I concur with the portions of this court's judgment that are directed to standing, the patentability of the cDNA claims, and the patentability of the method claims. I respectfully dissent, however, from the court's holding that Myriad's BRCA gene claims and its claims to gene fragments are patent-eligible. In my view, those claims are not directed to patentable subject matter, and if sustained the court's decision will likely have broad consequences, such as preempting methods for whole-genome sequencing, even though Myriad's contribution to the field is not remotely consonant with such effects.
In its simplest form, the question in this case is whether an individual can obtain patent rights to a human gene. From a common-sense point of view, most observers would answer, "Of course not. Patents are for inventions. A human gene is not an invention." The essence of Myriad's argument in this case is to say that it has not patented a human gene, but something quite different — an isolated human gene, which differs from a native gene because the process of extracting it results in changes in its molecular structure (although not in its genetic code). We are therefore required to decide whether the process of isolating genetic material from a human DNA molecule makes the isolated genetic material a patentable invention. The court concludes that it does; I conclude that it does not.
At the outset, it is important to identify the inventive contribution underlying Myriad's patents. Myriad was not the first to map a BRCA gene to its chromosomal location. That discovery was made by a team of researchers led by Dr. Mary-Claire King. See Jeff M. Hall et al., Linkage of Early-Onset Familial Breast Cancer to Chromosome 17q21, 250 Science 1684 (1990). And Myriad did not invent a new method of nucleotide sequencing. Instead, it applied known sequencing techniques to identify the nucleotide order of the BRCA genes.
Of course, Myriad is free to patent applications of its discovery. As the first party with knowledge of the sequences, Myriad
As the majority and concurring opinions explain, the claims at issue in this case fall into three categories: claims that cover the isolated BRCA genes (claim 1 of the '282 patent, claim 1 of the '473 patent, and claims 1 and 6 of the '492 patent); claims that cover only the BRCA cDNA (claims 2 and 7 of the '282 patent and claim 7 of the '492 patent); and claims that cover portions of the BRCA genes and cDNA as small as 15 nucleotides long (claims 5 and 6 of the '282 patent). I first address the claims to the BRCA genes.
In the seminal case of Diamond v. Chakrabarty,
The Court in Chakrabarty held the artificial life form at issue in that case to be patentable because the claim was "not to a hitherto unknown natural phenomenon, but to a nonnaturally occurring manufacture or composition of matter — a product of human ingenuity `having a distinctive name, character [and] use.'" Id. at 309-10, 100 S.Ct. 2204, quoting Hartranft v. Wiegmann,
Myriad's claims to the isolated BRCA genes seem to me to fall clearly on the "unpatentable" side of the line the Court drew in Chakrabarty. Myriad is claiming the genes themselves, which appear in nature on the chromosomes of living human beings. The only material change made to those genes from their natural state is the change that is necessarily incidental to the extraction of the genes from the environment in which they are found in nature. While the process of extraction is no doubt difficult, and may itself be patentable, the isolated genes are not materially different from the native genes. In this respect, the genes are analogous to the "new mineral discovered in the earth," or the "new plant found in the wild" that the Supreme Court referred to in Chakrabarty. It may be very difficult to extract the newly found mineral or to find, extract, and propagate the newly discovered plant. But that does not make those naturally occurring items the products of invention.
The same is true for human genes. Like some minerals, they are hard to extract from their natural setting. Also like minerals, they can be used for purposes that would be infeasible if they remained in their natural setting. And the process of extracting minerals, or taking cuttings from wild plants, like the process of isolating genetic material, can result in some physical or chemical changes to the natural substance. But such changes do not make extracted minerals or plant cuttings patentable, and they should not have that effect for isolated genes. In each case, merely isolating the products of nature by extracting them from their natural location and making those alterations attendant to their extraction does not give the extractor the right to patent the products themselves.
The majority characterizes the isolated genes as "new molecules" and considers them different substances from the corresponding native DNA.
Although the majority insists that the changes in the DNA molecule that occur as part of the process of isolation render the gene claims patentable, the majority does not appear to take a similar position with respect to chemical elements. The government as amicus curiae argues that patenting the BRCA genes would be like patenting the element lithium. Isolated lithium does not occur naturally because it reacts with air and water and thus is found in nature only as part of a chemical compound, ionically bound to other elements. Robert E. Krebs, The History and Use of Our Earth's Chemical Elements 48 (2d ed.2006). Once isolated, lithium has many industrial applications, and in order to isolate lithium, it is necessary to break ionic bonds in the lithium compounds that are found in nature. But the majority acknowledges that elemental lithium (like other elements) would not be patentable subject matter because it "is the same element whether it is in the earth or isolated."
The principles underlying that analysis apply to genetic material as well. In order to isolate the BRCA gene, it is necessary to break chemical bonds that hold the gene in its place in the body, but the genetic coding sequence that is the subject of each of the BRCA gene claims remains the same whether the gene is in the body or isolated. The majority, however, does not agree that the cases are analogous, and indeed appears to have adopted the following rule: Isolated atoms are not patent eligible, but isolated molecules are.
Apart from the arbitrariness of such a rule, if we are to apply the conventional nomenclature of any field to determine whether Myriad's isolated DNA claims are "new," it would seem to make more sense to look to genetics, which provides the language of the claims, than to chemistry. Aside from Myriad's cDNA claims, its composition claims are not defined by any particular chemical formula. For example, claim 1 of the '282 patent covers all isolated DNAs coding for the BRCA1 protein, with the protein being defined by the amino acid sequence encoded by the naturally occurring BRCA1 gene. From a molecular perspective, that claim covers a truly immense range of substances from the cDNA that is 5,914 nucleotides long to the isolated gene that contains more than 120,000 nucleotides. And the patent does not define the upper end of that range because the patent does not identify a unique nucleotide sequence for the 120,000-nucleotide-long isolated BRCA1 gene. Instead, the patent contains a sequence that is just 24,000 nucleotides long with numerous gaps denoted "vvvvvvvvvvvvv." '282 patent, fig. 10. An almost incalculably large number of new molecules could be created by filling in those gaps with almost any nucleotide sequence, and all of those molecules would fall within the scope of claim 1. Included in that set are many important molecular variations to the BRCA1 gene that Myriad had not yet discovered and could not have chemically described. Yet those molecules would share only one unifying characteristic: each codes for the same protein as the naturally occurring BRCA1 gene.
From a genetic perspective, that claim covers one "composition of matter" — the BRCA1 gene. The isolated BRCA genes are identical to the BRCA genes found on chromosomes 13 and 17. They have the same sequence, they code for the same proteins, and they represent the same units of heredity. During the transcription phase of protein synthesis, the BRCA
In that respect, extracting a gene is akin to snapping a leaf from a tree. Like a gene, a leaf has a natural starting and stopping point. It buds during spring from the same place that it breaks off and falls during autumn. Yet prematurely plucking the leaf would not turn it into a human-made invention. See Intervet Inc. v. Merial Ltd.,
Both the majority and the concurring opinions attach significant weight to the fact that the claimed coding portions of the native BRCA genes are part of a much larger molecule and that the isolated BRCA genes, being smaller molecules extracted from the larger one, are therefore man-made inventions. But to argue that the isolated BRCA gene is patentable because in its native environment it is part of a much larger structure is no more persuasive than arguing that although an atom may not be patentable, a subatomic particle is patentable because it was previously part of a larger structure, or that while a tree is not patentable, a limb of the tree becomes a patentable invention when it is removed from the tree.
Of course, it is an over-simplification to say that something that can be characterized as "isolated" or "extracted" from its natural setting always remains a natural product and is not patentable. One could say, for example, that a baseball bat is "extracted" or "isolated" from an ash tree, but in that case the process of "extracting" the baseball bat necessarily changes the nature, form, and use of the ash tree and thus results in a manmade manufacture, not a naturally occurring product. In that setting, man has defined the parts that are to be retained and the parts that are to be discarded. The result of the process of selection is a product with a function that is entirely different from that of the raw material from which it was obtained. In the case of the BRCA genes, by contrast, nature has defined the genes as independent entities by virtue of their capacity for protein synthesis and, ultimately, trait inheritance. Biochemists extract the target genes along lines defined by nature so as to preserve the structure and function that the gene possessed in its natural environment. In such a case, the extraction of a product in a manner that retains the character and function of the product as found in nature does not result in the creation of a human invention.
Cases involving the "purification" of a natural substance employ similar analysis. Our predecessor court recognized that merely purifying a naturally occurring substance does not render the substance patentable unless it results in a marked change in functionality. In re Merz, 25 CCPA 1314,
In sum, the test employed by the Supreme Court in Chakrabarty requires us to focus on two things: (1) the similarity in structure between what is claimed and what is found in nature and (2) the similarity in utility between what is claimed and what is found in nature. What is claimed in the BRCA genes is the genetic coding material, and that material is the same, structurally and functionally, in both the native gene and the isolated form of the gene.
The structural differences between the claimed "isolated" genes and the corresponding portion of the native genes are irrelevant to the claim limitations, to the functioning of the genes, and to their utility in their isolated form. The use to which the genetic material can be put, i.e., determining its sequence in a clinical setting, is not a new use; it is only a consequence of possession. In order to sequence an isolated gene, each gene must function in the same manner in the laboratory as it does in the human body. Indeed, that identity of function in the isolated gene is the key to its value. Moreover, as Judge Moore's concurring opinion explains, Myriad has failed to credibly identify new uses for the isolated BRCA genes as probes or primers. The naturally occurring genetic material thus has not been altered in a way that would matter under the standard set forth in Chakrabarty. For that reason, the isolation of the naturally occurring genetic material does not make the claims to the isolated BRCA genes patent-eligible.
As noted, in addition to the BRCA gene claims discussed above, the claims at issue in this appeal include four claims to BRCA cDNA and two claims to portions of the BRCA genes and cDNA as small as 15 nucleotides long.
I agree with the court that the claims to BRCA cDNA are eligible for patenting. The cDNA cannot be isolated from nature, but instead must be created in the laboratory.
However, I disagree with the court as to the two claims to short segments of DNA having at least 15 nucleotides. Claim 6 of the '282 patent covers any sequence of the BRCA1 cDNA that is at least 15 nucleotides long. That claim encompasses each BRCA1 exon, even though each exon is naturally defined by transcription. Moreover, because small sequences of DNA are repeated throughout the three billion nucleotides of the human genome, the claim covers portions of the cDNA of more than 4% of human genes. It also covers portions of the DNA of nearly all human genes. Accordingly, efforts to sequence almost any gene could infringe claim 6 even though Myriad's specification has contributed nothing to human understanding of other genes.
Myriad could easily have claimed more narrowly to achieve the utility it attaches to segments of cDNA. It contends that those segments can be used as probes and primers. DNA probes must be chemically altered or "tagged" before they can be so used, and Myriad could have claimed the tagged segments to achieve probe functionality. A claim to tagged segments would not encompass the BRCA1 exons. As to primer functionality, many of the cDNA segments will not work. Some will be too long. Some will be too short. Some will be palindromic and fold in on themselves. Myriad could have identified a subset of the segments that work as primers, and such a claim could be patentable if it were limited to species with "markedly different characteristics from any found in nature and ... having the potential for significant utility." Chakrabarty, 447 U.S. at 310, 100 S.Ct. 2204. The problem with claim 6 is that it is so broad that it includes products of nature (the BRCA1 exons) and portions of other genes; its validity is not salvaged because it includes some species that are not natural. Accordingly, I would hold claim 6 unpatentable.
Myriad's last claim, claim 5 of the '282 patent, is breathtakingly broad. That claim covers any segment of the DNA defined by claim 1, provided that the segment is at least 15 nucleotides long. Claim 1, in turn, covers any isolated DNA that codes for the BRCA1 polypeptide. Thus, claim 5 would cover not only the isolated BRCA1 gene in each of its untold molecular variations, but also any sub-sequence of those molecules, including portions that fall in the undefined range of those molecules denoted "vvvvvvvvvvvvv." Claim 5 would therefore be unpatentable for the same reasons as claim 1 and claim 6.
Of course, in light of its breadth, claim 5 of the '282 patent is likely to be invalid on other grounds, and thus a ruling as to patent-eligibility with respect to that claim may be superfluous. Nonetheless, it is important to consider the effects of such broad patent claims on the biotechnology industry. While Myriad has emphasized the biotechnology industry's need of patent protection to encourage and reward research in this difficult and important field, there is another side to the coin. Broad claims to genetic material present a significant
My colleagues assign significant weight to the fact that since 2001 the PTO has had guidelines in place that have allowed patents on entire human genes. They conclude that those guidelines, and the PTO's earlier practice, are entitled to deference from this court as to the question whether patents to isolated human genes constitute patent-eligible subject matter. I think the PTO's practice and guidelines are not entitled to significant weight, for several reasons.
First, as we have recognized, the PTO lacks substantive rulemaking authority as to issues such as patentability. Animal Legal Def. Fund v. Quigg,
Second, whatever force the PTO's views on the issue of patent eligibility may have had in the past has, at the very least, been substantially undermined by the position the government has taken in this case. The Department of Justice filed a brief on behalf of the United States in this court taking the position that Myriad's gene claims (other than the cDNA claims) are not patent-eligible. Although the PTO did not "sign" the brief and we are left to guess about the status of any possible continuing interagency disagreements about the issue, the Department of Justice speaks for the Executive Branch, and the PTO is part of the Executive Branch, so it is fair to assume that the Executive Branch has modified its position from the
Finally, prior to the Supreme Court's decision in Chakrabarty, the PTO had determined that microorganisms were not subject to patenting, but the Supreme Court gave no indication that it regarded that view as entitled to deference. Moreover, the Court gave short shrift to the Commissioner's contention (which was made the lead argument in its brief) that the patentability of life-forms was an issue that should be left to Congress. Citing Marbury v. Madison, 5 U.S. (1 Cranch) 137, 2 L.Ed. 60 (1803), the Court explained that "Congress has performed its constitutional role in defining patentable subject matter in § 101; we perform ours in construing the language Congress has employed." Chakrabarty, 447 U.S. at 315, 100 S.Ct. 2204. We have the same responsibility and should not shy away from deciding the issues of law that the parties have brought to us. Although my colleagues believe our analysis of the legal question in this case should be influenced by purported expectations of the inventing community based on the PTO's past practice of issuing patents on human genes, that is in effect to give the PTO lawmaking authority that Congress has not accorded it.
