MEMORANDUM OPINION

Plaintiff Cephalon, Inc., a Delaware corporation with its principal place of business in

Pennsylvania, has sued Kathleen Sebelius, the Secretary of Health and Human Services, and

Margaret Hamburg, the Commissioner of the Food and Drug Administration, in their official

capacities. Plaintiff, the manufacturer of Fentora, a name brand or “pioneer” drug, brings this

suit under the Administrative Procedure Act, 5 U.S.C. § 701 et seq., claiming that the Food and

Drug Administration (“FDA”) erroneously approved a generic version of Fentora. Before the

Court is defendants’ motion to dismiss for lack of subject matter jurisdiction on the grounds that

plaintiff lacks standing and its claims are not ripe. For the reasons set forth below, the Court will

dismiss this case because it is not ripe.

BACKGROUND

I. REGULATORY FRAMEWORK

Under the Federal Food, Drug, and Cosmetic Act, 21 U.S.C. § 301 et seq., a pioneer drug

may not be marketed until the FDA has approved a new drug application (“NDA”) that includes

“full reports of investigations which have been made to show whether or not such drug is safe for use and whether such drug is effective in use” and “a full statement of the composition of such

drug.” 21 U.S.C. § 355(b)(1). In addition, the pioneer manufacturer must provide the patent

number and expiration date of any patent related to the drug. Id. If the FDA approves the

pioneer drug, it is published in the FDA’s Approved Drug Products with Therapeutic

Equivalence Evaluations (the “Orange Book”). See id. The pioneer’s listing in the Orange Book

includes patents claiming the drug or its method of use. Id.

After a pioneer drug is approved, a generic manufacturer may obtain FDA approval to

market a generic version by submitting an Abbreviated New Drug Application (“ANDA”). 21

U.S.C. § 355(j). Instead of relying on its own clinical studies to prove that the generic is

effective, the generic manufacturer can show, among other things, that its drug is the same as the

pioneer drug in terms of active ingredient(s), route of administration, dosage form, and strength,

and that the generic is bioequivalent to the pioneer drug. 21 U.S.C. § 355(j)(2)(A). If the

pioneer contains a single active ingredient, the ANDA must include “information to show that

the active ingredient of the new drug is the same as that of the listed drug.” 21 U.S.C. §

355(j)(2)(A)(ii)(I).

Submission of an ANDA constitutes a patent infringement of patents claiming the

pioneer drug. 35 U.S.C. § 271(e)(2). Thus, if the generic manufacturer wants to market its drug

before the requisite patent(s) in the Orange Book expires, the generic manufacturer must show

“that such patent is invalid or will not be infringed by the manufacture, use, or sale of the

[generic] drug for which the application is submitted.” 21 U.S.C. § 355(j)(2)(A)(vii)(IV).

II. FACTUAL HISTORY

Plaintiff manufactures the pioneer drug Fentora, which is a “potent opioid analgesic” that

is used to treat breakthrough pain in cancer patients who have become tolerant to other opioids.

(Complaint [“Compl.”] at ¶ 16.) Fentora contains a single active ingredient, fentanyl citrate,

2 which is a Schedule II narcotic. (Id. at ¶ 17.) Fentora comes in a tablet, which is placed inside

the patient’s mouth to allow the tablet to disintegrate and deliver the fentanyl citrate to the

patient’s body. (Id.) Clinical studies have shown that pain relief occurs in patients from fifteen

to thirty minutes after placing the tablet in the mouth. (Id.) Cephalon listed at least two patents

for Fentora in the Orange Book. A third patent, U.S. Patent No. 6,264,981 (“the ‘981 patent”),

was ineligible for listing in the Orange Book 1 but was filed with the United States Patent and

Trade Office on October 27, 1999, and the patent will expire in 2019. (Defendant’s Motion to

Dismiss [“Def.’s Mot.”] at 3-4 & nn.4-5.) The FDA approved Fentora on September 25, 2006.

(Compl. at ¶ 16.)

Watson Laboratories, Inc. (“Watson”) filed an ANDA for a generic version of Fentora

(“the Watson generic”) on July 10, 2007, which was ultimately approved by the FDA on January

7, 2011. (Id. at ¶¶ 18, 25; Def.’s Mot. at 3.) Between the filing of the ANDA and its approval

three and a half years later, plaintiff took a number of steps to delay or prevent approval.

Plaintiff first attempted to block Watson’s ANDA by filing a patent infringement claim based on

the two Orange Book patents on June 2, 2008, in federal court in Delaware. (Compl. at ¶ 18.)

Plaintiff filed a second patent infringement claim based on the ‘981 patent in the same court on

September 25, 2009. (Id.) The court consolidated both claims and held a bench trial. Cephalon,

Inc. v. Watson Pharms., Inc., No. 08-330, 2011 WL 845376, at *1 (D. Del. Mar. 11, 2011)

[hereinafter Cephalon I].

During the trial, plaintiff learned that the manufacturing process for the Watson generic

could potentially create a second active ingredient (in addition to fentanyl citrate) and that the

FDA had knowledge of that possibility. (Compl. at ¶¶ 18, 19.) Based on that information, 1 Because the ‘981 patent describes manufacturing methods, and the Orange Book lists approved drug products, it cannot be listed in the Orange Book. (See Def.’s Mot. at 3 n.4.)

3 plaintiff filed a citizen petition with the FDA on July 13, 2010, arguing that the second active

ingredient should have prevented the FDA from approving the Watson generic because the

FDA’s regulations require that the pioneer and the generic have the same active ingredient. (Id.

at ¶ 23.) Plaintiff filed a second citizen petition on July 23, 2010. (Id. at ¶ 24.) In that petition,

plaintiff asked the FDA “to revise its bioequivalence guidelines” to accommodate Fentora’s

rapid release of fentanyl citrate by requiring generic manufacturers to prove that the generic

could be absorbed into the body as quickly as Fentora. (Id.) On January 7, 2011 (the same day

that the FDA approved the Watson generic), the FDA denied both petitions. (Id. at ¶ 25.)

On March 11, 2011, the Delaware court ruled against plaintiff in the first patent suit.

Cephalon I, 2011 WL 845376, at *27. However, on March 25, 2011, the court ruled for plaintiff

on the second patent claim, finding that the Watson generic violated the ‘981 patent. Cephalon,

Inc. v. Watson Pharms., Inc., No. 09-724, 2011 WL 1088008, at *23 (D. Del. Mar. 24, 2011)

[hereinafter Cephalon II]. Following that decision, Cephalon and Watson entered a stipulated

agreement and the district court issued a permanent injunction barring Watson from infringing
