DYK, Circuit Judge.
This case presents a question under the Hatch-Waxman Amendments to the Federal
The overall scheme of the Hatch-Waxman Amendments is described in detail in our decisions in Mylan and Andrx and need not be repeated here. The facts of this case are relatively simple considering the complexity of the statutory scheme.
3M is the assignee of U.S. Patent No. 4,642,384 (the "'384 patent"). The '384 patent claims intermediate compounds that result from a process for producing a drug product containing the active ingredient flecainide acetate.
Barr also sought to piggyback on the approval of 3M's NDA and filed an ANDA on May 22, 2000. Barr provided its paragraph IV certification that it did not infringe the '384 patent to 3M by letter dated July 12, 2000. As the second ANDA filer, Barr was not only potentially subject to the thirty-month stay under 21 U.S.C. § 355(j)(5)(B)(iii) (if 3M filed an infringement suit) but also to a 180-day stay pursuant to § 355(j)(5)(B)(iv) of the statute, which provides:
This provision is designed to provide an incentive, in the form of a 180-day period of marketing exclusivity, to an ANDA filer that is the first to challenge a patent listed in the Orange Book. The running of the 180-day period is triggered by "the Secretary['s] receiv[ing] notice from the [first ANDA applicant] of [its] first commercial marketing of the drug" or by "a decision of a court in an action described in [21 U.S.C. § 355(j)(5)(B)(iii)] holding the patent which is the subject of the certification to be invalid or not infringed." 21 U.S.C. § 355(j)(5)(B)(iv). Since Alphapharm has apparently not commenced marketing, we are concerned here with the second triggering condition a "decision of a court in an action described in [21 U.S.C. § 355(j)(5)(B)(iii)] holding the patent which is the subject of the certification to be invalid or not infringed." 21 U.S.C. § 355(j)(5)(B)(iv)(II). This provision has been construed by the District of Columbia Circuit to include not only a successful judgment of noninfringement or invalidity in a suit against the first ANDA filer but also a successful judgment of noninfringement or invalidity in a suit brought against a later ANDA filer. Teva Pharms., USA, Inc. v. United States FDA, 182 F.3d 1003, 1010, 51 USPQ2d 1432, 1437 (D.C.Cir.1999).
Following Barr's initial notice to 3M of its paragraph IV certification, 3M sought additional information from Barr regarding its noninfringement position and on August 10, 2000, Barr elaborated, stating that "[a]s detailed in our letter dated July 12, 2000, Barr's proposed product does not
Unsatisfied by Barr's claim of noninfringement, 3M filed an infringement suit against Barr in the district of Minnesota on August 25, 2000. Alphapharm intervened because of its interest in delaying approval of Barr's ANDA application. Because 3M filed this suit within 45 days of receiving notice of Barr's paragraph IV certification, the thirty-month or litigation termination stay period under 21 U.S.C. § 355(j)(5)(B)(iii) was triggered with respect to Barr. Barr brought counterclaims seeking, among other things, a declaration of noninfringement. Barr also moved for summary judgment of noninfringement.
In the course of discovery, information was disclosed by Barr that convinced 3M that Barr did not infringe the '384 patent. 3M sought to dismiss its suit without prejudice, because, it urged, a dismissal without prejudice would prevent the triggering of Alphapharm's 180-day period of exclusivity. In effect, 3M sought to prevent approval of Barr's ANDA until 180 days after Alphapharm began marketing its approved product. 3M urged that Barr had "hoodwinked" 3M into filing a suit by refusing to provide a more detailed statement as to why it did not infringe the '384 patent.
The district court declined to dismiss 3M's action without prejudice. The district court recognized that the decision whether to allow a party to voluntarily dismiss an action after filing, pursuant to Rule 41(a)(2), is generally within the discretion of the district court, and that under governing Eighth Circuit law factors to consider in exercising this discretion include: whether the party has presented a proper explanation for its desire to dismiss; whether a dismissal would result in a waste of judicial time and effort; whether a dismissal would prejudice the defendant; and whether the dismissal was designed to avoid an adverse judgment. Minn. Mining & Mfg. Co. v. Barr Labs., Inc., 139 F.Supp.2d 1109, 1115 (D.Minn. 2001). The district court found no impropriety in Barr's declining to provide further information before 3M brought suit, finding specifically that "Barr's assurances [that it did not infringe the '384 patent], together with 3M's knowledge that other methods existed for producing flecainide acetate [that did not involve producing the claimed intermediate compounds], were sufficient to satisfy the notice requirements of the ANDA process." Id. at 1115. The district court further found that 3M was merely attempting to avoid an adverse judgment in the district court proceeding and was therefore not entitled to a voluntary dismissal. Id. at 1116. Finally, the district court granted Barr's motion for summary judgment of noninfringement because 3M did not object to Barr's motion on the merits. Id. 3M and Alphapharm filed this timely appeal. We heard argument on March 7, 2002.
While we review the district court's decision not to allow 3M to voluntarily dismiss its action for abuse of discretion, L.E.A. Dynatech, Inc. v. Allina, 49 F.3d 1527, 1530, 33 USPQ2d 1839, 1841 (Fed.Cir.1995), the issue here is primarily a legal one — whether the district court was required to dismiss without prejudice or whether it grounded its dismissal on an erroneous proposition of law — namely Barr's compliance with the requirement of
A predicate to appellants' arguments is that a dismissal with prejudice would trigger the running of the 180-day period. The District of Columbia Circuit has explicitly held that § 355(j)(5)(B)(iv)(II) is triggered by the termination of an action commenced by the second ANDA filer, and we agree. Teva, 182 F.3d at 1010, 51 USPQ2d at 1438. As the district court here noted "it would be contrary to the very purpose of the Act to allow the first filer to block market entry of other generic manufacturers because the first filer is involved in protracted litigation." Minn. Mining, 139 F.Supp.2d at 1115.
3M argues that the district court lacked subject matter jurisdiction and therefore should have dismissed the action without prejudice because, after filing the infringement action, 3M agreed that no infringement had occurred. The suggestion that the district court originally lacked subject matter jurisdiction is unfounded and incorrect. There was a clear controversy between 3M and Barr as to whether the '384 patent was infringed. The mere fact that 3M may have been operating under a misapprehension of the facts cannot affect the original subject matter jurisdiction of the district court.
However, if this case did not involve the Hatch-Waxman Amendments, appellants might well be correct that a case or controversy ceased to exist in the course of the litigation when 3M represented that it no longer claimed infringement by Barr. See Fina Research, S.A. v. Baroid Ltd., 141 F.3d 1479, 1483-84, 46 USPQ2d 1461, 1465 (Fed.Cir.1998). But the case does involve the Hatch-Waxman Amendments, and the parties strenuously disagree about whether the action should be dismissed with or without prejudice. 3M urges that the form of dismissal could have significant consequences in the FDA proceedings. Whether or not 3M is correct that the form of dismissal will have consequences in the FDA proceedings,
Appellants urge that the district court was obligated to use its inherent power to sanction misconduct by Barr by dismissing the action without prejudice. Initially in their briefs to this court appellants complained that Barr had "hoodwinked" 3M into filing suit, and had violated a duty under the Federal Rules of Civil Procedure to disclose facts to 3M that would have resulted in a decision to forgo suit. Appellants argued, as well, that Barr could not properly cause the initiation of baseless litigation by 3M to secure an advantage under the Hatch-Waxman Amendments. We are aware of no such pre-filing disclosure obligation. Nor did Barr have any obligation to avoid triggering litigation that would advantage Barr by starting the 180-day exclusivity period.
3M's claim concerning compliance with the paragraph IV certification requirement is not insubstantial. The statute requires that:
21 U.S.C. § 355(j)(2)(B) (emphasis added). The FDA has interpreted this statute to require, inter alia, "(i) [f]or each claim of a patent alleged not to be infringed, a full and detailed explanation of why the claim is not infringed[; and] (ii)[f]or each claim of a patent alleged to be invalid or unenforceable, a full and detailed explanation of the grounds supporting the allegation." 21 C.F.R. § 314.52(c)(6).
In Barr's initial July 12, 2000, notification to 3M, it stated that its proposed drug product would not infringe any claim of the '384 patent because "the active ingredient [in the proposed product] is ... not the
The appellants argue that this notice was legally deficient under the statute because Barr's statement that its "proposed product does not contain any of the compounds claimed in the '384 patent" was at best ambiguous. Appellants urge that Barr, by referring to its statements in the July 12, 2000, letter, indicated that its noninfringement position had not changed, and that Barr still based its opinion of noninfringement on a comparison between the active ingredient in its proposed product and the claimed compounds, rather than on a comparison between any compounds in the proposed product and the compounds claimed in the '384 patent.
However, we hold that we need not, indeed cannot, decide this question of compliance with the paragraph IV certification requirements. Under the Hatch-Waxman Amendments we cannot enforce the requirements of paragraph IV certifications in an infringement suit.
In our decision in Mylan we confronted a claim that a particular patent listing in the Orange Book was improper because the listed patent did not claim a drug for which an NDA had been submitted, as required by 21 U.S.C. § 355(b)(1). Mylan, 268 F.3d at 1332, 60 USPQ2d at 1588. In Mylan, the ANDA applicant sued the FDA and the NDA holder, alleging that the pertinent patent had been improperly listed in the Orange Book, and moved for declaratory and injunctive relief requiring the NDA holder to take measures to delist the patent from the Orange Book and requiring the FDA to immediately approve the ANDA. Id. at 1328, 268 F.3d 1323, 60 USPQ2d at 1580. The district court issued injunctions requiring the private defendant to withdraw the Orange Book listing and requiring the FDA to approve the ANDA. Mylan Pharms., Inc. v. Thompson, 139 F.Supp.2d 1, 29-30 (D.D.C.2001). The private defendant appealed, arguing that the FFDCA did not grant a private right of action, but the FDA did not appeal.
On appeal, the appellee-ANDA applicant (the declaratory judgment plaintiff) urged that its action was proper because it arose under the patent laws (Title 35 of the United States Code). The ANDA applicant claimed that its declaratory judgment action asserted a defense to patent infringement, because listing in the Orange Book was an element of any patent infringement cause of action which the NDA holder might have asserted. Mylan, 268 F.3d at 1330-31, 60 USPQ2d at 1581-82. We rejected the ANDA applicant's attempt to bring its action under the patent laws because we concluded that its cause of action was not tied to any recognized patent infringement defense but rather was "an attempt to assert a private right of action for `delisting' under the FFDCA." Id. at 1332, 268 F.3d 1323, 60 USPQ2d at 1583. We also made clear that there was
We reaffirmed this holding in Andrx. In Andrx, in an infringement action between a patentee and an ANDA filer, the district court shortened the thirty-month stay period, citing 21 U.S.C. § 355(j)(5)(B)(iii), because it found that the patentee's listing of the second patent in the Orange Book was done improperly to delay the resolution of the patent actions between the parties. We reversed, holding that "the district court ha[d] no authority in the infringement action, as opposed to an action under the Administrative Procedure Act, to shorten the thirty-month stay because of allegedly improper conduct before the FDA." Andrx at 1376, 276 F.3d 1368, 61 USPQ2d at 1419. We held that a claim of improper conduct in the FDA proceeding was required to be raised initially before the FDA itself and thereafter in a judicial review proceeding brought under the APA. Id. at 1379, 276 F.3d 1368, 61 USPQ2d at 1421.
We conclude that this case is governed by Mylan and Andrx. Like Mylan, 3M here attempts to assert a private right of action under the FFDCA because of another party's alleged failure to comply with the statute. As we held in Mylan,
Mylan at 1332. Accordingly, we hold that appellants cannot seek a judicial determination of whether a private party's paragraph IV certification complies with 21 U.S.C. § 355(j)(2)(B). Thus, the district court should not have decided the issue of compliance.
We also hold that the district court did not abuse its discretion in ordering a dismissal with prejudice. Under Federal Rule of Civil Procedure 41(a)(2), once an answer or a motion for summary judgment has been filed, an action may be dismissed at the plaintiff's request only upon order of the court and upon such terms and conditions as the court deems proper. Here, because the district court's dismissal with prejudice was not contrary to law, we review that decision for an abuse of discretion, applying the law of the Eighth Circuit. Hamm v. Rhone-Pôulenc Rorer Pharms., Inc., 187 F.3d 941, 948 (8th Cir.1999), cert. denied, 528 U.S. 1117, 120 S.Ct. 937, 145 L.Ed.2d 815 (2000). The district court here considered appellant's claimed entitlement to a dismissal without prejudice under Rule 41(a)(2), but found no legitimate justification for the appellants to dismiss the action without prejudice. The district court concluded that the appellants were seeking to avoid a judgment that would be adverse to their interest in delaying Barr's entrance in the market and that this was not a legitimate justification for their desire to dismiss without prejudice. Minn. Mining, 139 F.Supp.2d at 1116.
Finally, in affirming the judgment of the district court, we think it appropriate to make clear what we are not deciding. First, we do not decide whether parties such as 3M and Alphapharm have standing to complain to the FDA, and to maintain a suit under the APA, concerning Barr's satisfaction of the paragraph IV certification requirement, nor do we decide when and whether the FDA must address such claims.
For the foregoing reasons, we affirm.
GAJARSA, Circuit Judge, concurring in judgment.
I agree with the majority that the judgment of the district court should be affirmed; however, I disagree with their attempt to impose an administrative requirement by an expansive interpretation
On the one hand, the majority affirms the lower court because it did not abuse its discretion in dismissing the action with prejudice after determining that the notice sent to 3M by Barr was in compliance with 21 U.S.C. § 355(j)(2)(B)(ii). Maj. Op. at 783. On the other hand, the majority holds that section 355(j)(2)(B)(ii) cannot be enforced by a private party in a patent infringement action but must be enforced in the context of the Administrative Procedure Act ("APA"). Maj. Op. at 782-83. It is inconsistent to say that the trial court did not abuse its discretion in finding the notice sufficient in a non-APA action and thereby dismissing the action with prejudice, and then to conclude that the sufficiency of notice cannot be considered outside the context of the APA. If it is the case that the sufficiency of the notice cannot be considered, then the appropriate remedy is not to affirm the dismissal with prejudice but to remand to the district court to either stay the action pending administrative review of the sufficiency, or dismiss the action without prejudice so that it can be brought after the FDA has reviewed the sufficiency of the notice. Either way, affirming the district court implicitly condones its authority to assess the sufficiency of the notice. Moreover, the determination of who has authority to consider the sufficiency of notice is not necessary to resolve the issue before us. Once this court decides that there has been no abuse of discretion, the case is resolved. Furthermore, the issue of who can properly determine the sufficiency of notice was not raised below and was not briefed before us. Therefore, the holding with respect to the determination of section 355(j)(2)(B) is unadulterated sophistry.
The majority opinion fails to recognize the requirements of the specific policies expressed by the Congress when it enacted the Abbreviated New Drug Application ("ANDA") statutory scheme, 21 U.S.C. § 355(j). The statute was an attempt by the Congress to balance the competing interests between the patented drug and the generic drug manufacturers. In order to create an incentive for generic manufacturers, Congress provided the first manufacturer to successfully challenge a drug patent with a 180-day exclusivity period.
I. The Definition of "Court Decision"
The relevant statutory provision 21 U.S.C. § 355(j)(5)(B)(iv)(II)
II. The Availability of a "Court Decision"
The Congressional policy with respect to generic drugs is clear: generic manufacturing of a drug should be allowed as soon as it is determined that it does not violate patent rights. Given this policy, the statute's provisions on the exclusivity period should not be read to reach nonsensical results. It should not be the case that a second ANDA filer whose method may infringe a patent can bring a suit that can trigger the exclusivity period, while a second ANDA filer whose method clearly does not infringe a patent cannot. In an effort to avoid this potential problem that has not yet been addressed by this court, Barr Labs, in this case, availed itself of the opportunities provided by the statutory scheme, by giving notice (albeit ambiguous) and inducing 3M to bring an action against them. The majority today, instead of addressing the correct interpretation of the statutory scheme and quelling the need for anyone to exploit the system, places another hurdle before the ANDA filers who clearly do not infringe: they must now survive administrative challenge to their paragraph IV certification notice before they can obtain a favorable judgment. There is no doubt that this process will increase the time period required to resolve these time-sensitive cases because district court infringement suits will need to be stayed pending administrative proceedings or may not be brought if the NDA patentee avails himself of the APA procedures proposed by the majority.
III. The Creation of an Unnecessary Administrative Quagmire
Today the majority extends the requirement of Mylan Pharmaceuticals, Inc. v. Thompson and Andrx Pharmaceuticals, Inc. v. Biovail Corp. beyond the necessary demands of the statute. Mylan, 268 F.3d 1323, 60 USPQ2d 1576 (Fed.Cir.2001); Andrx, 276 F.3d 1368, 61 USPQ2d 1414 (Fed.Cir.2002). In both of those cases the issue was whether or not the FDA had taken proper action in listing patents in the Orange Book. In Mylan, the ANDA applicant sued the FDA and the New Drug Application ("NDA") holder alleging that the pertinent patent had been improperly listed in the Orange Book. Mylan, 268 F.3d at 1328, 60 USPQ2d at 1580. This court held that there was no private cause of action for de-listing a patent. Id. at 1332, 268 F.3d 1323, 60 USPQ2d at 1583. In Andrx, the ANDA applicant had complained before the district court that the FDA and the NDA patentee had improperly listed a patent in the Orange Book in violation of the APA and that they improperly stayed approval of Andrx's ANDA based on the patentee's filing of a new patent, which the FDA said triggered a new 30-month stay period. Andrx, 276 F.3d at 1373-74, 61 USPQ2d at 1415-16.
Moreover, the proposed shift of the burden to the FDA is not required. The majority now metamorphosizes into an APA action the sufficiency of the statutory notice requirement, failing to perceive that under subparagraph 355(j)(2)(B)(i) an applicant who makes a paragraph IV certification "shall include in the application a statement that the applicant will give notice required by clause (ii) to —
The statute does not require the notice to be filed with the FDA, the body now given the task of adjudicating its sufficiency. Moreover, the FDA regulations, which are in compliance with the statute, state that "[a] copy of the notice itself need not be submitted to the agency." 21 C.F.R. § 314.95 (2001). This court is imposing its own independent requirement that the notice be subject to an APA proceeding. We are substituting our interpretation of the statute over the FDA's regulatory requirement by such an imposition.
Indeed the FDA has stated that the sufficiency of the notice is an issue to be resolved by the applicant and the patent owner without involvement of the FDA. The FDA published responses to comments about the proposed notice rules in the Federal Register. With respect to 21 C.F.R. § 314.52, which is almost identical to 21 C.F.R. § 314.95 but relates to the filing of subsequent NDAs which may infringe listed patents instead of ANDAs which may infringe listed patents, the FDA stated:
Abbreviated New Drug Application Regulations; Patent Exclusivity Provisions, 59 Fed.Reg. 50338, 50342 (October 3, 1994) (emphasis added).
With respect to § 314.95, which relates to ANDAs, the FDA stated:
Id. at 50349-50 (emphasis added).
Thus, there is no doubt that FDA has no intention of entering into disputes over the sufficiency of the notice, and indeed is unqualified to do so. The statute is silent on the question of who determines the sufficiency of notice. Given such a statutory ambiguity, this court must defer to the agency's reasonable interpretation of the statute. Chevron, U.S.A., Inc. v. Natural Res. Def. Council, Inc., 467 U.S. 837, 843-44, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984). The FDA has reasonably interpreted the statute to mean that the FDA should not review the sufficiency of the notice. This court must defer to that interpretation.
IV. The Declaratory Judgment as the "Court Decision"
The majority's addition of new administrative obstacles certainly deters Barr-like behavior, but it does so by creating a disincentive to challenging drug patents. Yet the problem with Barr's type of "hoodwinking" is not that we do not want companies to challenge drug patents. The problem is that there is no sense in making second ANDA filers go through this labyrinth to trigger the exclusivity period that they have every right to trigger. Congress wanted second ANDA filers to be able to manufacture their drugs quickly if they could prove noninfringement. In a case where proving noninfringement is effortless, it should be a simple process.
Appellants argue that it would be frivolous for someone in Barr's position to seek a declaratory judgment of noninfringement. Therefore, appellants assert, Barr would have no standing to bring a declaratory judgment action.
Congress contemplated the availability of a declaratory judgment action in this context. Subsection (j)(5)(B)(iii) states:
21 U.S.C. § 355(j)(5)(B)(iii) (Supp. V 1999) (emphasis added). This language indicates that while a declaratory judgment action is not available for ANDA filers during the forty-five day period, it is available after that period.
This court has repeatedly articulated the requirements for a declaratory judgment action in patent suits.
Cordis Corp. v. Medtronic, Inc., 835 F.2d 859, 862, 5 USPQ2d 1118, 1120 (Fed.Cir.1987) (citing, inter alia, Jervis B. Webb Co. v. Southern Sys., Inc., 742 F.2d 1388, 1398-99, 222 USPQ 943, 949 (Fed.Cir.1984)); see also Sandt Tech., Ltd. v. Resco Metal and Plastics Corp., 264 F.3d 1344, 1356 n. 4, 60 USPQ2d 1091, 1098 n. 4, (Fed.Cir.2001). The second prong of the test has been characterized as requiring "present activity which could constitute infringement or concrete steps taken with the intent to conduct such activity." BP Chems. Ltd. v. Union Carbide Corp.,
Given that Congress contemplated the availability of declaratory judgment actions for ANDA filers, as seen in subsection (j)(5)(B)(iii), the language of 21 U.S.C. § 355(b)(1) setting forth the requirements for filing a NDA is not coincidental. That section states, in pertinent part that:
21 U.S.C. § 355(b)(1) (emphasis added). Thus, by the terms of the statute, filing an NDA application meets prong one of the declaratory judgment case or controversy requirement, because filing the application requires the patentee to maintain that an infringement suit could "reasonably be asserted" against one who "engages in the manufacture, use or sale of the drug." This is "conduct giving rise to a reasonable apprehension on the plaintiff's part that it will face an infringement suit or the threat of one." Cordis, 835 F.2d at 862, 5 USPQ2d at 1120.
Prong two is also met by statutory terms under 35 U.S.C. § 271 which defines submitting an ANDA application under § 355(j) for a drug claimed in a patent or the use of which is claimed in a patent to be an act of infringement. Eli Lilly and Co. v. Medtronic, Inc., 496 U.S. 661, 678, 110 S.Ct. 2683, 110 L.Ed.2d 605 (1990). This clearly meets the test as a "present activity which could constitute infringement."
Therefore, the logical conclusion, which also solves the dilemma in this case, is to make it clear that a declaratory judgment suit is available for ANDA filers who are not sued by the NDA patentee within the 45-day period. The two acts of (1) a patentee listing a patent in the Orange Book through the filing of a NDA, and (2) a generic manufacturer filing an ANDA, together meet the case or controversy requirement so as to allow a declaratory judgment action of noninfringement.
It is noteworthy that the District of Columbia Circuit, which also handles a large number of ANDA cases, has suggested an alternative method of explaining the availability of declaratory judgment actions in this context. In Mova Pharmaceutical Corp. v. Shalala, the court stated,
140 F.3d 1060, 1073 n. 18, 46 USPQ2d 1385, 1396 n. 18 (D.C.Cir.1998) (citations omitted). Therefore, the inability to market a product without a court decision may create sufficient case or controversy for purposes of a declaratory judgment action. Certainly, in cases such as this, there is a controversy over whether a triggering decision is permissible, and the parties have much at stake in that determination.
Whether the basis for a case or controversy for declaratory judgment purposes is
V. The Majority's Loose Ends
In addition, Part VII of the majority opinion continues its illogical pursuit by positing numerous issues that it does not decide, including the standing of parties to bring an APA administrative proceeding before the FDA. If we do not decide them, then all of these observations and conclusions are advisory and dicta. It is unnecessary to delineate them in order to decide this appeal.
Because I find the majority's holding to be inconsistent with the goals established by Congress and inconsistent with the internal logic of the statute, I concur in judgment only.
21 U.S.C. § 355(j)(5)(B)(iv) (Supp. V 1999).
