Nucleonics, Inc. ("Nucleonics") appeals from the judgment of dismissal for lack of subject matter jurisdiction entered by the United States District Court for the District
On March 22, 2004, Benitec sued Nucleonics for infringing U.S. Patent No. 6,573,099 ("'099 patent"), which relates to RNA-based disease therapy. Both parties are biotechnology companies that are engaged in gene silencing, which involves silencing the expression of disease-causing genes. A cell is exposed to a piece of foreign DNA that is specifically engineered to contain certain portions or copies of the target gene to be silenced. The foreign DNA then produces other molecules (double-stranded RNA) that shut down the expression of the target gene. This technology is known as RNA interference ("RNAi") gene silencing.
Nucleonics filed a timely answer to the complaint on March 24, 2004. On July 13, 2004, Nucleonics moved to dismiss Benitec's complaint and argued:
Further, Nucleonics contended that:
The court denied the motion, but without prejudice to reconsideration depending upon the outcome of the Supreme Court's review of Integra Lifesciences I, Ltd. v. Merck KGaA, 331 F.3d 860 (Fed.Cir.2003).
On October 4, 2004, Nucleonics filed a request with the U.S. Patent and Trademark Office ("PTO") for reexamination of the '099 patent.
In 2005, Benitec encountered a pair of obstacles. First, Nucleonics received evidence indicating that the inventor named in the '099 patent may have misappropriated the idea for the invention from others, or at least should have named others as co-inventors on the patent application. On February 16, 2005, Nucleonics sought leave of court to amend its answer and add declaratory relief counterclaims of invalidity and unenforceability based upon alleged inventorship fraud. After some discovery skirmishes, Nucleonics obtained testimony in June 2005 from Australian scientists Peter Waterhouse and Ming-Bo Wang that they had contributed to the subject matter of the '099 patent. Neither, however, is named as an inventor in the '099 patent.
Second, and in the same month, the Supreme Court decided Merck KGaA v. Integra Lifesciences I, Ltd., reading expansively the pharmaceutical research exception of § 271(e)(1). 545 U.S. 193, 125 S.Ct. 2372, 162 L.Ed.2d 160 (2005).
The district court granted Nucleonics's motion to amend its answer on September 14, 2005. Two weeks later, however, the court granted Benitec's motion to dismiss its complaint without prejudice and dismissed Nucleonics's counterclaims for lack of jurisdiction under the Declaratory Judgment Act, 28 U.S.C. §§ 2201-02.
During the time between the filing of Nucleonics's motion to amend to assert its counterclaims and the court's dismissal of those counterclaims, Nucleonics allegedly began discussing expanding its efforts beyond human health to animal husbandry and veterinary products.
Nucleonics appeals the dismissal of its declaratory judgment counterclaims. In its appellee's brief, Benitec "covenants and promises not to sue Nucleonics for patent infringement arising from activities and/or products occurring on or before the date dismissal was entered in this action — September 29, 2005."
The critical question on appeal is whether, in light of the circumstances, the court at this time has declaratory judgment jurisdiction over Nucleonics's counterclaims seeking declarations of invalidity and unenforceability of Benitec's '099 patent.
Subsequent to the oral argument in this case, the Supreme Court decided MedImmune, Inc. v. Genentech, Inc., ___ U.S. ___, 127 S.Ct. 764, 166 L.Ed.2d 604 (2007). In view of that decision, particularly footnote 11 expressing disapproval of our previously used "reasonable apprehension of imminent suit" test for determining declaratory judgment jurisdiction,
A party seeking to base jurisdiction on the Declaratory Judgment Act bears the burden of proving that the facts alleged, "`under all the circumstances, show that there is a substantial controversy, between the parties having adverse legal interests, of sufficient immediacy and reality to warrant the issuance of a declaratory judgment.'" MedImmune, 127 S.Ct. at 771 (quoting Md. Cas. Co. v. Pac. Coal & Oil Co., 312 U.S. 270, 273, 61 S.Ct. 510, 85 L.Ed. 826 (1941)). Prior to MedImmune, our case law required that there be "both (1) an explicit threat or other action by the patentee, which creates a reasonable apprehension on the part of the declaratory plaintiff that it will face an infringement
127 S.Ct. at 771 (internal citation and quotations omitted).
In SanDisk, we further explain:
SanDisk, 480 F.3d at 1381. A useful question to ask in determining whether an actual controversy exists is what, if any, cause of action the declaratory judgment defendant may have against the declaratory judgment plaintiff:
Microchip Tech. Inc. v. Chamberlain Group, Inc., 441 F.3d 936, 943 (Fed.Cir. 2006).
The burden is on the party claiming declaratory judgment jurisdiction to establish that such jurisdiction existed at the time the claim for declaratory relief was filed and that it has continued since. See Steffel v. Thompson, 415 U.S. 452, 459 n. 10, 94 S.Ct. 1209, 39 L.Ed.2d 505 (1974); Super Sack Mfg. Corp. v. Chase Packaging Corp., 57 F.3d 1054, 1058 (Fed.Cir.1995); Int'l Med. Prosthetics Research Assocs., Inc. v. Gore Enter. Holdings, Inc., 787 F.2d 572, 575 (Fed.Cir.1986). "If . . . a party has actually been charged with infringement of the patent, there is, necessarily, a case or controversy adequate to support jurisdiction" at that time. Cardinal Chem. Co. v. Morton Int'l, Inc., 508 U.S. 83, 96, 113 S.Ct. 1967, 124 L.Ed.2d 1 (1993). Further, once that burden has been met, absent further information, that
The dissent's view that Cardinal Chemical holds that "the burden shifts to the party seeking to divest the court of jurisdiction to prove there is no longer a current case or controversy" reads more into the language of Cardinal Chemical than is justified. First, the Supreme Court makes clear at the outset of its opinion that "[the] practice [the Federal Circuit's uniform practice of declaring the issue of validity moot if it affirms the district court's finding of noninfringement], and the issue before us, therefore concern the jurisdiction of an intermediate appellate court — not the jurisdiction of either a trial court or this Court. In the trial court, of course, a party seeking a declaratory judgment has the burden of establishing the existence of an actual case or controversy." 508 U.S. at 95, 113 S.Ct. 1967. Further, the Court only said that "[i]f a party to an appeal suggests that the controversy has, since the rendering of the judgment below, become moot, that party bears the burden of coming forward with subsequent events that have produced that alleged result." Id. at 98, 113 S.Ct. 1967 (emphasis added). The Court did not hold that the ultimate burden of proof in the trial court was on other than the party seeking to invoke declaratory judgment jurisdiction.
With the basic principles for determining declaratory judgment jurisdiction in mind, we analyze the question of whether the court currently has declaratory judgment jurisdiction over Nucleonics's counterclaims.
1. Declaratory Judgment Jurisdiction Existed at the Time Nucleonics Filed it Counterclaims
At the time Nucleonics filed its counterclaims for declarations of invalidity and unenforceability, Benitec's patent infringement claims were pending. Because Nucleonics had been charged with infringement of the '099 patent, there was, as dictated by Cardinal Chemical, necessarily a case or controversy adequate to support jurisdiction at that time. See id.
2. Declaratory Judgment Jurisdiction at the Present Time
a. Human Application of RNAi
Cardinal Chemical, however, does not address whether subsequent events can divest the district court of jurisdiction, specifically here, over Nucleonics's counterclaims. This court has rejected the argument that subsequent events cannot divest the trial court of jurisdiction, noting that Cardinal Chemical dealt primarily with this court's previous practice of vacating findings of patent invalidity as moot in light of non-infringement. Super Sack, 57 F.3d at 1060; see also Amana Refrigeration, Inc. v. Quadlux, Inc., 172 F.3d 852, 855 (Fed.Cir.1999).
In Super Sack, we found that Super Sack's unconditional agreement "not to sue Chase for infringement as to any claim of the patents-in-suit based upon the products currently manufactured and sold by Chase" was sufficient to divest the court of jurisdiction over Chase's counterclaims for non-infringement, invalidity and unenforceability
In Amana Refrigeration, Amana sued Quadlux for "declaratory judgments of patent invalidity and noninfringement." 172 F.3d at 855. Quadlux responded with a promise not to sue Amana for patent infringement based on the patent-in-suit "as it presently reads, with respect to any product currently advertised, manufactured, marketed or sold by Amana, or any product which was advertised, manufactured, marketed or sold by Amana prior to the date of" the promise. Id. We held that this promise divested the district court of jurisdiction, notwithstanding that at some indefinite point in the future, Amana might develop new products or the PTO might reissue the patent-in-suit with altered claims. Id. at 855-56.
Although neither Super Sack nor Amana has been expressly overruled, both applied the disapproved "reasonable apprehension of imminent suit" test. Therefore, although the holdings in both cases are not necessarily dependent on the "reasonable apprehension of imminent suit" requirement, we nevertheless base our analysis of whether jurisdiction currently exists over Nucleonics's declaratory judgment counterclaims strictly on the framework of MedImmune.
Nucleonics is currently researching applications of RNAi with an eye to treating human diseases, such as hepatitis B. Section 271(e)(1) of Title 35 of the United States Code provides:
The parties have now both taken the position that Nucleonics's present activities related to the human medical application of RNAi are, in light of § 271 and the Supreme Court's decision in Merck, not infringing and cannot become infringing until after Nucleonics files a new drug application ("NDA") with the U.S. Food and Drug Administration ("FDA"). Nucleonics took this position, which the dissent does not mention, even before the decision in Merck. Benitec acknowledged lack of infringement later when it moved to dismiss its infringement claims. Nucleonics does not even anticipate filing an NDA before "at least 2010-2012, if ever." Therefore, Nucleonics's activities of developing and submitting information to the FDA related to human application of RNAi does not present a case or controversy of sufficient immediacy and reality to warrant declaratory judgment jurisdiction over the enforceability of the '099 patent. The fact that Nucleonics may file an NDA in a few years does not provide the immediacy and reality required for a declaratory judgment. The situation is analogous to that in Telectronics Pacing Systems, Inc. v. Ventritex, Inc., 982 F.2d 1520,
Nucleonics argues that Fort James Corp. v. Solo Cup Co., 412 F.3d 1340, 1342 (Fed.Cir.2005), supports its position that the court has jurisdiction. In Fort James, the plaintiff sued Solo Cup for infringement of three patents. Solo Cup "counterclaimed for declarations that the patents were invalid, unenforceable, and not infringed." Id. at 1343. The district court bifurcated the proceedings; all issues were to be tried to a jury first, except Solo Cup's unenforceability counterclaim, which was to be tried by the court following the jury trial. Id. at 1344. The jury found that one of the patents-in-suit was neither invalid nor infringed. Id. at 1345. Fort James then promised not to sue Solo Cup on any of the three patents for any product Solo Cup currently or previously manufactured and to "not seek to overturn the jury's verdict." Id. Solo Cup nonetheless wished to press forward with its declaratory claim for invalidity of one of the patents. Id. We held that there was still declaratory judgment jurisdiction over Solo Cup's counterclaim. Id. at 1349. The majority stated that Fort James's promise not to sue "had no effect on Fort James's claim for infringement, because that controversy had already been resolved by the jury's verdict." Id. at 1348. The majority concluded that "the jury verdict holding that Solo Cup did not infringe Fort James's patents did not moot Solo Cup's counterclaim for unenforceability nor did it act to divest the district court of jurisdiction to hear that unlitigated counterclaim." Id.
Contrary to Nucleonic's assertions, Fort James does not compel jurisdiction here. The instant setting is different because no trial of the infringement issue has taken place. Benitec instead had its claims dismissed at its request before a trial and the considerable effort connected therewith had taken place. The court in Fort James distinguished Super Sack on this "unique procedural posture":
Id. at 1348.
In SanDisk, we did hold that the statement of STMicroelectronics NV's ("ST") vice president of intellectual property and licensing that "ST has absolutely no plan whatsoever to sue SanDisk" did not eliminate the justiciable controversy created by ST's actions. 480 F.3d at 1382. However, ST's statement was made when ST had engaged in a course of conduct that showed a willingness to enforce its patent rights despite its vice-president's statement. ST had approached SanDisk having made a studied and considered determination of infringement by SanDisk and having communicated that determination to SanDisk. It then only stated that it did not intend to sue SanDisk; it did not say it would not sue SanDisk in the future for its alleged infringement. Id. at 1382-83. In the instant case, Benitec made its covenant and sought dismissal of its infringement claim after it concluded that the Merck
b. Animal Application of RNAi
Nucleonics now states, however, that it wishes to expand into animal RNAi products. Such products presumably would not be protected from infringement by § 271(e)(1) because they would appear to fall within its parenthetical exception to the safe harbor that excepts from infringement protection any "new animal drug or veterinary biological product . . . which is primarily manufactured using recombinant DNA, recombinant RNA, hybridoma technology, or other processes involving site specific genetic manipulation techniques."
Nucleonics submitted to the district court the declaration of its president
Nucleonics argues that the evidence offered by its president shows a justiciable case or controversy that supports declaratory judgment jurisdiction over its potential expansion to animal husbandry and veterinary products. To be liable as an infringer, Nucleonics must be one who "without authority makes, uses, offers to sell, or sells" a product that infringes the '099 patent. See 35 U.S.C. § 271(a). There was no evidence before the district court that Nucleonics had made or sold any infringing product.
The meaning of "offer to sell" in § 271(a) is the offer of common law contracts. Rotec Indus. v. Mitsubishi Corp., 215 F.3d 1246, 1254-55 (Fed.Cir.2000). The declaration of Nucleonics's president does not indicate that Nucleonics's desire to expand into animal markets has yet produced any definite offer which the unnamed "supplier of breeding stock" could accept. Nucleonics has not shown that it is engaged in any "use" of the patented invention that could subject it to an infringement suit by Benitec. Nucleonics has therefore not met its burden of showing that it is engaged in any present activity that could subject it to a claim of infringement by Benitec. See Microchip Tech., 441 F.3d at 943. In other words, Nucleonics has not shown that its discussions regarding expansion into animal husbandry and veterinary products meet the immediacy and reality requirement of MedImmune. See MedImmune, 127 S.Ct. at 771.
Nucleonics has also failed to show that its future plans meet the immediacy and
First, Nucleonics's only steps toward potentially-infringing animal research are discussions with an unnamed potential customer and execution of an undescribed confidentiality agreement. Nucleonics merely "expects" to begin work "shortly." We do not doubt the veracity of Nucleonics's president's statements — indeed, there is no evidence to the contrary. However, to allow such a scant showing to provoke a declaratory judgment suit would be to allow nearly anyone who so desired to challenge a patent.
Second, and particularly given the uncertain contours of § 271(e)(1), see Merck, 545 U.S. at 202, 125 S.Ct. 2372, Nucleonics has provided insufficient information for a court to assess whether Nucleonics's possible future animal work would be infringing or not. The Supreme Court in Merck held that § 271(e)(1) "exempted from infringement all uses of patented compounds `reasonably related' to the process of developing information for submission under any federal law regulating the manufacture, use, or distribution of drugs." 545 U.S. at 206, 125 S.Ct. 2372 (emphases in original). Although the allegedly infringing activity at issue in Merck did not implicate § 271(e)(1)'s parenthetical exception for animal drugs, here, based on the evidence Nucleonics has presented, one cannot tell if Nucleonics intends to undertake activity that would fall within § 271(e)(1)'s parenthetical exception or would otherwise be infringing.
Third, although Benitec originally argued that animal testing for human use was infringing activity, it has now concluded that such testing falls within § 271(e)(1)'s protection. Benitec has never challenged use of the technology in testing in animals for animal use and claims another company owns any right to do so. In any event, there is no evidence of a justiciable controversy between Benitec and Nucleonics over Nucleonics's vaguely defined potential expansion to animal husbandry and veterinary products.
We recognize that Nucleonics would like to remove any concerns it or its potential investors might have over possible infringement of the Benitec patent. We do not express an opinion on whether Nucleonics's animal work could ever be the subject of an infringement suit. We merely hold that Nucleonics did not carry its burden of showing an existing justiciable controversy. As we observed in Teva:
482 F.3d at 1338-39 (internal quotations and citation omitted). We also recognize that Nucleonics wishes to receive the benefit of a ruling on the validity and scope of Benitec's patent now, while Nucleonics undertakes any nascent animal work. There is currently, however, no "substantial controversy, between [Benitec and Nucleonics], of sufficient immediacy and reality to warrant the issusance of a declaratory judgment." MedImmune, 127 S.Ct. at 771. And there may never be.
Nucleonics has not made a showing of "sufficient immediacy and reality" to support declaratory judgment jurisdiction. The district court's judgment of dismissal for lack of jurisdiction is affirmed.
If this declaratory judgment action were filed today, I would agree with the majority that the required case or controversy had not been established. I also agree that there must be a case or controversy at all stages of the litigation. See Steffel v. Thompson, 415 U.S. 452, 459 n. 10, 94 S.Ct. 1209, 39 L.Ed.2d 505 (1974). However, in my view, a different test for determining whether there is a case or controversy applies when the allegation of infringement is withdrawn during the course of litigation. Supreme Court precedent requires that, if a patentee files an infringement lawsuit and the particular claim of infringement is mooted, a counterclaim for invalidity should not be dismissed unless the patentee demonstrates that there is no possibility of a future controversy with respect to invalidity. See Cardinal Chem. Co. v. Morton Int'l, Inc., 508 U.S. 83, 98, 113 S.Ct. 1967, 124 L.Ed.2d 1 (1993). In my view, Benitec made no such showing.
There is a strong public interest in permitting accused infringers to challenge invalid or unenforceable patents. See Cardinal Chem., 508 U.S. at 100, 113 S.Ct. 1967; Blonder-Tongue Labs., Inc. v. Univ. of Ill. Found., 402 U.S. 313, 345-47, 91 S.Ct. 1434, 28 L.Ed.2d 788 (1971); Lear, Inc. v. Adkins, 395 U.S. 653, 663-64, 89 S.Ct. 1902, 23 L.Ed.2d 610 (1969); Altvater v. Freeman, 319 U.S. 359, 364-65, 63 S.Ct. 1115, 87 L.Ed. 1450 (1943). The Declaratory Judgment Act, 28 U.S.C. §§ 2201-02 (1934), plays an important role in facilitating such challenges, in particular by preventing patent holders from threatening enforcement while avoiding litigation that might render the patent invalid or unenforceable. See Arrowhead Indus. Water, Inc. v. Ecolochem, Inc., 846 F.2d 731, 734-35 (Fed.Cir.1988). The Supreme Court in MedImmune, Inc. v. Genentech, Inc., ___ U.S. ___, 127 S.Ct. 764, 166 L.Ed.2d 604 (2007), has recently emphasized the importance the Declaratory Judgment Act plays in protecting against the Hobson's choice of abandoning lawful endeavors or risking liability for infringement.
Here Benitec sued Nucleonics for infringement of Benitec's patent, broadly alleging that Nucleonics is "engaged in making, using, offering to sell, and selling gene silencing technologies that are the same or equivalent to the technologies claimed in the Benitec patent." J.A. at 71. Nucleonics timely answered the complaint, denying infringement and, nearly ten months later, moved to add declaratory judgment counterclaims asserting invalidity and unenforceability. At the time of Nucleonics's counterclaim filing, it was clear that there was declaratory jurisdiction because "[i]f . . . a party has actually been charged with infringement of the patent, there is, necessarily, a case or controversy adequate to support jurisdiction of a complaint, or a counterclaim, under the Act." Cardinal Chem., 508 U.S. at 96, 113 S.Ct. 1967 (emphasis in original); see also Arrowhead, 846 F.2d at 736.
Nonetheless, the majority holds that when the accused infringer has been sued
Here the patentee's manipulative efforts to defeat declaratory jurisdiction are clear enough. After Nucleonics moved to add the counterclaims, the Supreme Court decided Merck KGaA v. Integra Lifesciences I, Ltd., 545 U.S. 193, 125 S.Ct. 2372, 162 L.Ed.2d 160 (2005), which addressed the 35 U.S.C. § 271(e)(1) safe harbor for research.
Following the Merck decision, Benitec, suggesting that it was unlikely to prevail on infringement claims directed to research on medical compounds for humans, filed a motion to dismiss the case without prejudice under Federal Rule of Civil Procedure 41(a)(2), asserting that there was no longer a continuing case or controversy. As the majority appears to recognize, op. at 1342-43, the motion may well have been motivated by a desire to avoid a patent invalidity determination.
Benitec did not offer a formal covenant not to sue before the district court. Rather, it stated in its motion to dismiss that it "could only bring new claims if Nucleonics is ultimately successful in obtaining FDA approval for its infringing products or otherwise engages in infringing activities not otherwise permitted under the § 271(e) exemption." J.A. at 1379. Nucleonics opposed the motion to dismiss on several grounds, including that there was a continuing controversy because it had taken "concrete steps . . . with the intent to conduct" allegedly infringing activity, including research on drugs for animals. BP Chems. Ltd. v. Union Carbide Corp., 4 F.3d 975, 978 (Fed.Cir.1993).
Nucleonics filed this appeal, arguing that Benitec's statement was insufficient to eliminate declaratory jurisdiction. In an effort to defeat jurisdiction, Benitec expanded its representation, stating that its argument to the district court included—and was intended to include—a promise "not to sue Nucleonics for patent infringement arising from activities and/or products occurring on or before the date dismissal was entered in this action—September 29, 2005." Appellee's Br. 45. At oral argument, Benitec again purported to clarify its covenant. Benitec stated that it would not sue "for any research that was going on prior to the dismissal" or "for animal research that was done at the time of the dismissal." Notably, Benitec offered no covenant with respect to future human or animal products or animal research.
The majority holds that Nucleonics has the burden of demonstrating a continuing case or controversy as narrowed by Benitec's promises. Op. at 1344. It concludes that Nucleonics has not met this burden as to either its human application of RNAi or its animal application of RNAi. Op. at 1347, 1349. In my view, the majority applies an erroneous test.
The Supreme Court has clearly established that once declaratory jurisdiction has been established, the burden shifts to the party seeking to divest the court of jurisdiction to prove that there is no longer a current case or controversy. See Cardinal Chem., 508 U.S. at 98, 113 S.Ct. 1967. In Cardinal Chemical, we initially held that a finding of non-infringement moots a declaratory counterclaim for invalidity. Id. at 87, 113 S.Ct. 1967. The Supreme Court reversed finding that "it is perfectly clear that the District Court had jurisdiction to entertain Cardinal's counterclaim" because "if . . . a party has actually been charged with infringement of the patent, there is, necessarily, a case or controversy adequate to support jurisdiction of a complaint, or a counterclaim, under the Act." Id. at 96, 113 S.Ct. 1967 (emphasis in original). The Court explained that while the initial burden of establishing declaratory judgment jurisdiction rests on the party seeking a declaratory judgment, "once that burden has been met courts are entitled to presume, absent further information, that jurisdiction continues." Id. at 98, 113 S.Ct. 1967.
In explaining the policy reasons for shifting the burden, the Court stated that "[a] company once charged with infringement must remain concerned about the risk of similar charges if it develops and markets similar products in the future." Id. at 99-100, 113 S.Ct. 1967. Moreover, declining jurisdiction over invalidity counterclaims "creates [the] potential for relitigation and imposes ongoing burdens on competitors who are convinced that a patent [is] invalid." Id. at 101, 113 S.Ct. 1967; see also Textron Lycoming Reciprocating Engine Div., Avco Corp. v. United Auto., Aerospace and Agric. Implement Workers of Am., 523 U.S. 653, 660, 118 S.Ct. 1626, 140 L.Ed.2d 863 (1998) ("[T]he only question is whether the parties had any concrete dispute over the contract's voidability
The majority distinguishes Cardinal Chemical as resting on the fact that at the time of the alleged mootness the case was on appeal after a judgment of non-infringement, but there is nothing in the Supreme Court's decision that restricts its burden-shifting holding to that limited context. Op. at 1345. Contrary to the majority, Cardinal Chemical cannot be limited to mootness at the court of appeals level. If a case is not moot when the case is on appeal, it can hardly be moot in identical circumstances at the district court level. Our decisions holding that Cardinal Chemical does not compel a district court to decide an invalidity counterclaim after entering a judgment of non-infringement are best understood as recognizing district court discretion under the Declaratory Judgment Act.
In any event, this is not a case in which the patentee suffered an adverse judgment, but rather one in which it voluntarily abandoned its infringement suit in the light of unfavorable developments. It is particularly inappropriate to place the burden of establishing continuing jurisdiction on declaratory plaintiffs where, as here, the claim of mootness is the result of the opposing party's acts designed, at least in part, to defeat declaratory jurisdiction. "[T]here is an important public interest in protecting the legal system against manipulation by parties, especially those prone to involvement in repeat litigation, who might contrive to moot cases that otherwise would be likely to produce unfavorable precedents." Hart and Wechsler, The Federal Courts and the Federal System 204 (5th ed.2003); see also Phillips Plastics Corp. v. Kato Hatsujou Kabushiki Kaisha, 57 F.3d 1051, 1053 (Fed.Cir.1995) ("[O]ne who may become liable for infringement should not be subject to manipulation by a patentee who uses careful phrases in order to avoid explicit threats, thus denying recourse to the courts while damages accrue.").
In the closely related injunction context, the Supreme Court has repeatedly held that the defendant carries a heavy burden of demonstrating that a case is moot when it voluntarily ceases the accused conduct. As the Supreme Court noted in Iron Arrow Honor Society v. Heckler, 464 U.S. 67, 72, 104 S.Ct. 373, 78 L.Ed.2d 58 (1983), "[d]efendants face a heavy burden to establish mootness in such cases because otherwise they would simply be free to `return to [their] old ways' after the threat of a lawsuit had passed. . . . Thus they must establish that `there is no reasonable likelihood that the wrong will be repeated.'" (quoting United States v. W.T. Grant Co., 345 U.S. 629, 632, 73 S.Ct. 894, 97 L.Ed. 1303 (1953)); see also Public Serv. Co. of Colo. v. Shoshone-Bannock Tribes, 30 F.3d 1203, 1206 n. 3 (9th Cir. 1994). Similarly in Friends of the Earth,
In my view, the patentee here has not come close to meeting its burden to show that there will be no future controversy. Even if we were to assume that there is no longer any possible controversy concerning Nucleonics's research on human drugs, there is a possibility that Nucleonics may in the future make human drugs that Benitec would challenge as infringing. Nucleonics has also stated that it intends to pursue animal research. While I agree with the majority that the future controversy would not satisfy the sufficient immediacy and reality test for the filing of a new suit today, Benitec has made no effort to demonstrate that the controversy between the parties will not recur. In fact, when asked at oral argument whether Benitec was "promising not to sue [Nucleonics] for animal product research that they begin" the day after argument, Benitec's counsel responded, "We have not made that statement that we would forebear suing them." Here Benitec's success in defeating declaratory jurisdiction will have the effect of inhibiting Nucleonics's ability to raise funds and conduct research and development. Nucleonics has stated that the threat of litigation has "hampered its efforts to obtain funding and to continue its business activities." Appellant's Br. 45 n. 19. Benitec has not satisfied its burden to eliminate any future controversy concerning infringement of the '099 patent.
The majority's decision here is not only inconsistent with the Supreme Court precedent; it exposes an inconsistency in this court's own jurisprudence. We have twice previously addressed the question of continuing declaratory jurisdiction in suits for infringement where the patent holder has attempted to defeat continuing jurisdiction by a covenant not to sue. See Fort James Corp. v. Solo Cup Co., 412 F.3d 1340 (Fed. Cir.2005); Super Sack Mfg. Corp. v. Chase Packaging Corp., 57 F.3d 1054 (Fed.Cir. 1995). As the majority recognizes, op. at 1345-46, those cases rested on our now-rejected reasonable apprehension test, and may no longer be good law after MedImmune, 127 S.Ct. at 774 n. 11. But assuming that they are still good law, they in fact conflict with each other.
In Super Sack, 57 F.3d 1054, we held that a covenant not to sue defeated jurisdiction, though we noted that the accused infringer "never contended that it ha[d] taken meaningful preparatory steps toward an infringing activity by planning to make a new product that may later be said to infringe," and that "[t]he residual possibility of a future infringement suit based on [the accused infringer's] future acts is simply too speculative a basis for jurisdiction
The effect of today's decision is to limit the availability of declaratory jurisdiction to challenge invalid and unenforceable patents by allowing patentees to moot such controversies by dismissing the original infringement action and covenanting not to bring suit on existing products, without any showing that the controversy will not recur in the future. I respectfully dissent.
