DYK, Circuit Judge.
Biovail Corporation ("Biovail") appeals an order of the United States District Court for the Southern District of Florida. Pursuant to 21 U.S.C. § 355(j)(5)(B)(iii), the district court (1) shortened the statutory thirty-month delay of approval of Andrx Pharmaceuticals, Inc.'s ("Andrx") pending Abbreviated New Drug Application ("ANDA") by the Food and Drug Administration ("FDA") and (2) ordered that the ANDA be approved by the FDA. Andrx Pharms., Inc. v. Biovail Corp., 175 F.Supp.2d 1362 (S.D.Fla. 2001). We hold that the district court exceeded its authority under 21 U.S.C. § 355(j)(5)(B)(iii). Accordingly, we vacate the district court's order and remand for further proceedings.
I
This case requires an interpretation of the statute which governs new and generic drug approvals and the enforcement of patents related to such drugs. This court has recently described the background and operation of this statute in Mylan Pharmaceuticals, Inc. v. Thompson, 268 F.3d 1323, 1325-27, 60 USPQ2d 1576, 1577-79 (Fed.Cir.2001). We briefly review it again here.
Under the Drug Price Competition and Patent Term Restoration Act of 1984, Pub.L. No. 98-417, 98 Stat. 1585 (1984), codified at 21 U.S.C. §§ 355, 360cc, and 35 U.S.C. §§ 156, 271, (the "Hatch Waxman Amendments" to the Federal Food, Drug
Also under the Hatch-Waxman Amendments, a pioneer drug manufacturer that holds an approved NDA is required to notify the FDA of all patents that "claim[ ] the drug for which the [NDA] applicant submitted the application...." 21 U.S.C. § 355(b)(1), (c)(2). The FDA lists such patents in its Approved Drug Products With Therapeutic Equivalence Evaluations (otherwise known as the "Orange Book"). Under 35 U.S.C. section 71(e)(1), it is not patent infringement to conduct otherwise infringing acts necessary to prepare an ANDA. Under section 271(e)(2), however, a generic drug manufacturer infringes a patent by filing an ANDA to obtain approval for a generic drug product claimed by a valid and unexpired patent.
As part of the approval process, an ANDA applicant must make a certification addressing each patent listed in the Orange Book that claims the drug. 21 U.S.C. § 355(j)(2)(A)(vii). An applicant whose ANDA is pending when a pioneer drug manufacturer lists additional patents in the Orange Book must make amended certifications addressing the newly listed patents claiming the drug, unless the patents are listed more than thirty days after they were issued. 21 C.F.R. § 314.94(a)(12)(vi). In either case, the ANDA applicant must certify that (I) no such patent information has been submitted to the FDA; (II) the patent has expired; (III) the patent is set to expire on a certain date; or (IV) the patent is invalid or will not be infringed by the manufacture, use, or sale of the new generic drug for which the ANDA is submitted. 21 U.S.C. § 355(j)(2)(A)(vii)(I-IV). These are commonly referred to as paragraph I, II, III, and IV certifications.
When an ANDA contains a paragraph IV certification, the ANDA applicant must give notice to the patentee and the NDA holder and provide a detailed basis for its belief that the patent is not infringed, invalid, or unenforceable. 21 U.S.C. § 355(j)(2)(B)(i); 21 C.F.R. § 314.95(c)(6). The patentee then has forty-five days to sue the ANDA applicant for patent infringement, and the ANDA applicant may not file a declaratory judgment during this time (based on the filing of the ANDA application). 21 U.S.C. § 355(j)(5)(B)(iii). If the patentee does not sue, the ANDA will be approved. If the patentee does file suit, the FDA may not approve the ANDA until expiration of the patent, resolution of the suit, or thirty months after the patentee's receipt of notice, whichever is earlier. Id. The court in which the suit is pending may order a shorter or longer stay if "either party to the action fail[s] to reasonably cooperate in expediting the action...." Id.

The present controversy arose against this statutory background. Biovail's affiliate,
The parties have been litigating patent infringement issues related to Andrx's ANDA for some time now. Biovail received approval for its NDA on September 11, 1995. Subsequent to FDA approval of the NDA, Biovail certified to the FDA that U.S. Patent No. 5,529,791 (the "'791 patent"), which issued on June 25, 1996, claimed the drug for which Biovail submitted the NDA. The FDA listed the '791 patent in the Orange Book as claiming Tiazac.
On June 22, 1998, Andrx filed its ANDA application, which included a paragraph IV certification addressing the '791 patent. The certification stated that Andrx did not infringe the patent and that the patent was invalid. Andrx notified Biovail of its paragraph IV certification and, on October 7, 1998, Biovail sued Andrx in district court for infringement of the '791 patent. Pursuant to 21 U.S.C. § 355(j)(5)(B)(iii), the filing of the patent infringement action triggered an automatic stay of the approval of Andrx's ANDA for thirty months after Biovail received notice of Andrx's paragraph IV certification (i.e., until February 25, 2001) or until the patent litigation was resolved. After a bench trial, the district court entered a judgment of noninfringement in favor of Andrx, and this court affirmed on February 13, 2001. Biovail Corp. Int'l v. Andrx Pharms., Inc., 239 F.3d 1297, 57 USPQ2d 1813 (Fed.Cir.2001). Thus, but for the present dispute, the FDA would have approved Andrx's ANDA on or shortly after February 13, 2001.
On May 1, 1997, non-party Arnold Lippa filed a provisional application in the United States Patent and Trademark Office. On April 28, 1998, within the one-year window available to claim priority to the provisional application, Mr. Lippa filed a utility patent application. That application resulted in the issuance on December 19, 2000, of U.S. Patent No. 6,162,463 (the " '463 patent"), which claims an extended release formulation of diltiazem, the active ingredient in Tiazac. The parties apparently agree that Biovail did not participate in the prosecution of applications leading to the '463 patent, but in January 2001 Biovail acquired an exclusive license for the patent.
On January 8, 2001, Biovail filed a certification with the FDA supporting the listing of the '463 patent in the Orange Book. In a February 2, 2001, letter to Andrx the FDA stated that because of the listing of the '463 patent, it no longer intended to approve Andrx's ANDA upon the expiration of the thirty-month stay triggered by the infringement dispute concerning the '791 patent. In a letter to the FDA dated February 1, 2001, Andrx protested the listing of the '463 patent, claiming that the patent did not claim Tiazac, and requested that the FDA delist the patent from the Orange Book. The FDA twice sought a response from Biovail concerning Andrx's
Apparently, after issuance of the '463 patent, Biovail changed its process for manufacturing Tiazac and sought approval to market this new formulation of Tiazac. Biovail, in its statement of disputed material facts in the district court, stated, somewhat confusingly, that it "recently changed its manufacturing process for Tiazac" and that "[t]his change ... brings Tiazac within the scope of at least claim one of the ['463] patent." In seeking approval for the new formulation, Biovail argued to the FDA that the manufacturing change did not affect the safety and efficacy of Tiazac, and therefore that Biovail was not required to supplement its Tiazac NDA. The FDA's Director of Cardio Renal Drug Products in the Office of Drug Evaluation (the "Director"), however, disagreed in a March 23, 2001, letter to Biovail, and stated that the "FDA has concluded that the approved drug application does not provide for those manufacturing changes...." The Director required Biovail to submit a supplement to its NDA, which would have to be approved before Biovail would be permitted to market the drug product prepared according to the new manufacturing changes. Biovail, however, continued to protest that it did not need to supplement its NDA for the new formulation to be approved. According to Biovail and the FDA, proceedings in the matter are still ongoing at the FDA.
While these administrative proceedings were pending, Andrx filed the present suit in the Southern District of Florida on February 9, 2001, naming as defendants Biovail, the Secretary of Health and Human Services, the Acting Principal Deputy Commissioner of the FDA, and the FDA. Andrx sought a declaratory judgment that it did not infringe the '463 patent, and that the '463 patent was invalid, and alleged antitrust and various violations of state law. Additionally, Andrx sought the relief of "delisting" the '463 patent from the Orange Book and of shortening the thirty-month statutory period.
Andrx also filed a paragraph IV certification with the FDA, dated February 16, 2001, stating that it did not infringe the '463 patent and that the '463 patent was invalid. Biovail received notice of the certification on February 20, 2001. Forty-four days later, on April 5, 2001, Biovail filed suit in the Southern District of Florida, alleging that Andrx's paragraph IV certification constituted infringement of the '463 patent under 35 U.S.C. § 271(e)(2). Biovail urged that this triggered a thirty-month statutory stay period under 21 U.S.C. § 355(j)(5)(B)(iii).
The district court consolidated the two actions. The district court dismissed the counts of Andrx's complaint asserting a private cause of action under the FFDCA to delist the '463 patent from the Orange Book. Andrx Pharms., Inc. v. Biovail Corp., 175 F.Supp.2d 1362 (S.D.Fla.2001). In dismissing this part of the cause of action, the district court thus correctly anticipated this court's recent holding in Mylan, 268 F.3d at 1332-33, that a generic
Andrx, at 1368.
Andrx moved the district court to shorten the thirty-month statutory period, pursuant to 21 U.S.C. § 355(j)(5)(B)(iii), thus triggering the particular dispute that is now before us. That statute provides:
21 U.S.C. § 355(j)(5)(B)(iii) (emphasis added). Andrx urged that Biovail had already been granted one thirty-month stay (involving the '791 patent) and was not entitled to a second one (involving the '463 patent). Andrx also argued that after Biovail licensed the '463 patent it deliberately changed its formulation of its Tiazac drug product to fall within the claims of the '463 patent so that it could claim an additional stay period. On September 19, 2001, the district court granted Andrx's motion for summary judgment on the thirty-month stay issue.
The district court explained:
Andrx, at 1374 (emphasis added). The district court also rejected Biovail's argument "that it limit its analysis [of its authority to shorten the stay] to only the specific filings in ... the actual infringement action. Such a myopic approach to each listed patent would lead to a potentially endless listing of patents to prolong FDA approval of a generic competitor." Id. at 1375.
The second thirty-month stay (based on the '463 patent) would have ended on August 8, 2003. The district court ordered that "under 21 U.S.C. § 355(j)(5)(B)(iii) the statutory stay should end on September 27, 2001, and the FDA ... should approve Andrx's ANDA." Id. at 1375. The district court then granted Biovail's emergency motion to stay its order until October 1, 2001, to allow Biovail to seek a stay of the district court's order from this court. This court granted a stay in order to "preserve the status quo while the court is considering the parties' papers." Biovail appealed the district court's order to this court, and moved for a further stay of the district court's order, pending disposition of its appeal. Andrx opposed Biovail's motion. Biovail replied. Andrx moved for leave to file a surreply, with the surreply attached, which we have granted. The Biovail stay motion was referred to a motions panel. We reconstituted the motions panel as a merits panel and ordered oral argument, directing the parties to prepare to argue the merits of the case. We also allowed the FDA to appear and present oral argument. We heard oral argument from the parties on December 14, 2001, and we now decide the merits. We vacate the order of the district court and dismiss Biovail's motion for a stay of the district court's order as moot.

We review a district court's grant of summary judgment without deference. Rodime PLC v. Seagate Tech., Inc., 174 F.3d 1294, 1302, 50 USPQ2d 1429, 1434 (Fed.Cir.1999), cert. denied 528 U.S. 1115, 120 S.Ct. 933, 145 L.Ed.2d 812 (2000). We draw all reasonable inferences in favor of the non-movant. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 255, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). Interpretation of statutes governing the grant of summary judgment presents threshold questions of law that are reviewed without deference. Barton v. Adang, 162 F.3d 1140, 1144, 49 USPQ2d 1128, 1132 (Fed. Cir.1998); Madison Galleries, Ltd. v. United States, 870 F.2d 627, 629 (Fed.Cir.1989).
IV
Biovail makes two primary arguments as to why the district court erred in shortening the stay period under section 355(j)(5)(B)(iii). First, Biovail argues that the district court erred in its interpretation of that statute because the statute allows the thirty-month stay to be shortened only if the parties fail to expedite the infringement action once filed. In fact, the statute may be susceptible to another interpretation
Biovail's second argument is that the district court shortened the period based on Biovail's conduct in the FDA proceedings. Here, we agree that the district court erred. The district court shortened the stay period because it found that Biovail's "actions with regard to obtaining the '463 patent after tentative approval of Andrx's generic drug and changing the formulation of its own approved drug, Tiazac, to come within the newly obtained patent [was] done to impede or delay the expeditious resolution of the patent actions between Biovail and Andrx...." Andrx, at 1374. The court's ruling was based on what we believe was an overly broad reading of the statute. First, whether the patent claims the drug product that is being actually marketed has nothing to do with the propriety of the listing of the patent in the Orange Book. Rather, the critical question is the relationship of the patent to the drug products and drug substances covered by the NDA. See post n. 5. Thus, Biovail's changing of its manufacturing process could not have been designed to justify the listing of the '463 patent in the Orange Book.
V
Andrx argues that the district court's decision may be affirmed on the alternative ground that Andrx properly stated a claim under the Administrative Procedure Act and that the FDA's refusal
The FDA apparently declines to consider such issues. 21 C.F.R. § 314.53 provides a person may protest the listing of a patent submitted by the NDA holder if the person disputes the accuracy or relevance of the patent information submitted to the FDA. If such a protest is filed, the FDA will request the NDA holder to confirm the correctness of the information submitted. According to the regulation, however, "[u]nless the application holder withdraws
Apparently the FDA also disagrees with Andrx's second statutory argument, since it has treated the listing in the Orange Book of the '463 patent as requiring a new thirty-month stay of its approval of Andrx's ANDA.
Biovail argues that this court in Mylan held that a private party could not assert an APA claim for delisting against the FDA. We disagree. 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 including an injunction against the NDA holder to take measures to delist the patent from the Orange Book and an injunction against the FDA to immediately approve the ANDA. The district court issued the injunctions against both the private defendant and the FDA requiring the private defendant to withdraw the Orange Book listing and the FDA to approve the ANDA. Mylan Pharms., Inc. v. Thompson, 139 F.Supp.2d 1, 29 (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 holder urged that its cause of action arose under the patent laws (Title 35 of the United States Code) as 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. We rejected the ANDA holder'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. We also made clear that there was no private cause of action for delisting under the FFDCA. Id. However, we did not hold or suggest that an ANDA applicant may not sue the FDA directly under the APA to compel the FDA to approve the ANDA if the FDA's action in denying the ANDA is arbitrary, capricious, or not in accordance with law. Because the FDA did not appeal the injunction against it in Mylan, we stated that "[w]e therefore do
Under the APA, a person "adversely affected or aggrieved by agency action," including a "fail[ure] to act," is entitled to "judicial review thereof." 5 U.S.C. § 702. Agency action, or failure to act, is reviewable only if the action is a "final agency action for which there is no other adequate remedy in a court...." 5 U.S.C. § 704. If a party has standing and prevails under its APA claim, it is entitled to a remedy under the statute, which normally will be a vacatur of the agency's order. Am. Bioscience, Inc. v. Thompson, 269 F.3d 1077, 1084 (D.C.Cir.2001). The Supreme Court has long recognized that decisions of the FDA are subject to review under the APA. See Abbott Labs., Inc. v. Gardner, 387 U.S. 136, 140-41, 87 S.Ct. 1507, 18 L.Ed.2d 681 (1967) (FDA decisions and regulations under the FFDCA are reviewable under the APA); Weinberger v. Hynson, Westcott & Dunning, Inc., 412 U.S. 609, 627, 93 S.Ct. 2469, 37 L.Ed.2d 207 (1973) (holding that an FDA order that a drug is a "new drug" within the meaning of FFDCA and therefore requires the filing and approval of an NDA "is reviewable by the district court under the Administrative Procedure Act"). The District of Columbia Circuit has recognized that claims may be brought under the APA to compel the FDA to act in accordance with the Hatch Waxman Amendments on several occasions. For example, in American Bioscience, a patentee sued the FDA, alleging that the FDA had acted contrary to law when it approved an ANDA despite the listing of a pertinent patent in the Orange Book. The FDA had concluded that the patent had been listed more than thirty days after its date of issuance and that under 21 C.F.R. § 314.94(a)(12)(vi) it had therefore been improperly listed and that the ANDA applicant was not required to file a certification. The patent holder sought a declaratory judgment under the APA that the FDA erred in concluding that the patent had been listed more than thirty days after it issued, and in approving the ANDA. The court agreed that the FDA's approval of the ANDA was arbitrary and capricious and ordered that it be vacated. Id. at 1086. See also Mova Pharm. Corp. v. Shalala, 140 F.3d 1060, 1069, 46 USPQ2d 1385, 1391-92 (D.C.Cir.1998) (affirming a successful APA challenge to the FDA requirement that the first applicant to file an ANDA must first successfully defend a patent infringement suit before it can be granted 180 day period of marketing exclusivity with respect to other ANDA applicants).
Although we agree that claims might properly be brought under the APA in this case to challenge the FDA's failure to issue the ANDA,
VI
For the foregoing reasons, we vacate the decision of the district court and remand for further proceedings. This action is without prejudice to (1) any future order of the district court, not inconsistent with this opinion, shortening the thirty-month period pursuant to 21 U.S.C. § 355(j)(5)(B)(iii) on the ground that the parties are not complying with the statutory requirement to "reasonably cooperate in expediting the action"; (2) any effort by Andrx to amend its complaint to state a proper claim against the FDA under the Administrative Procedure Act for the FDA's refusal to issue the ANDA. We dismiss as moot Biovail's request for a stay of the district court's order.
