Opinion

OPINION

SLEET, District Judge.

I. INTRODUCTION

The plaintiff Merck & Co., Inc. (“Merck”) filed suit against the defendant Apotex, Inc. (“Apotex”) in the above-captioned matter, alleging that Apotex committed an act of patent infringement under 35 U.S.C. § 271(e)(2)(A). Merck moves to dismiss its complaint for lack of subject matter jurisdiction because, since filing suit, it has given Apotex a comprehensive covenant not to sue, which removed the controversy between the parties. For the reasons that follow, Merck’s motion is granted.

II. SUMMARY OF STATUTORY FRAMEWORK

The provisions of the Drug Price Competition and Patent Term Restoration Act of 1984 (the “Hatch-Waxman Amendments”) govern the generic drug approval process. 1 The Food and Drug Administration (“FDA” or “Agency”), provides the following summary explanation of the Act’s statutory provisions, at http://www.fda.gov/ cder/about/smallbiz/generic — exclusivity, htm, which the court incorporates in pertinent part:

The Hatch-Waxman Amendments are intended to balance two important public policy goals. First, drug manufacturers need meaningful market protection incentives to encourage the development of valuable new drugs. Second, once the statutory patent protection and marketing exclusivity for these new drugs has expired, the public benefits from the rapid availability of lower priced generic versions of the innovator drug.

The Hatch-Waxman Amendments amended the Federal Food, Drug, and Cosmetic (“FD & C”) Act and created *421 section 505(j). Section 505(j) established the abbreviated new drug application (“ANDA”) approval process, which permits generic versions of previously approved innovator drugs to be approved without submission of a full new drug application (“NDA”). An ANDA refers to a previously approved new drug application (the “listed drug”) and rehes upon the Agency’s finding of safety and effectiveness for that drug product. The timing of an ANDA approval depends in part on patent protections for the innovator drug. Innovator drug applicants must include in an NDA information about patents for the drug product that is the subject of the NDA. The FDA publishes patent information on approved drug products in the Agency’s publication “Approved Drug Products with Therapeutic Equivalence Evaluations,” otherwise known as the “Orange Book.” The FD & C Act requires that an ANDA contain a certification for each patent listed in the Orange Book for the innovator drug. This certification must state one of the following: (i) that the required patent information relating to such patent has not been filed; (ii) that such patent has expired; (iii) that the patent will expire on a particular date; or (iv) that such patent is invalid or will not be infringed by the drug, for which approval is being sought.

A certification under paragraph I or II permits the ANDA to be approved immediately, if it is otherwise eligible. A certification under paragraph III indicates that the ANDA may be approved on the patent expiration date. A paragraph IV certification begins a process in which the question of whether the listed patent is valid or will be infringed by the proposed generic product may be answered by the courts prior to the expiration of the patent. The ANDA applicant who files a paragraph IV certification to a listed patent must notify the patent owner and the NDA holder for the listed drug that it has filed an ANDA containing a patent challenge. The notice must include a detailed statement of the factual and legal basis for the ANDA applicant’s opinion that the patent is not valid or will not be infringed. The submission of an ANDA for a drug product claimed in a patent is an infringing act if the generic product is intended to be marketed before expiration of the patent, and therefore, the ANDA applicant who submits an application containing a paragraph IV certification may be sued for patent infringement. If the NDA sponsor or patent owner files a patent infringement suit against the ANDA applicant within 45 days of the receipt of notice, the FDA may not give final approval to the ANDA for at least 30 months from the date of the notice. This 30-month stay will apply unless the court reaches a decision earlier in the patent infringement case, or otherwise orders a longer or shorter period for the stay.

The statute provides an incentive of 180 days of market exclusivity to the “first” generic applicant who challenges a listed patent by filing a paragraph IV certification and running the risk of having to defend a patent infringement suit. The statute provides that the first applicant to file a substantially complete ANDA containing a paragraph IV certification to a listed patent will be eligible for a 180-day period of exclusivity beginning either from the date it begins commercial marketing of the generic drug product, or from the date of a court decision finding the patent invalid, unenforceable or not infringed, whichever is first. These two events — first commercial marketing and a court decision favorable to the generic — are often called “triggering” events, because under the statute they can trigger the beginning of the 180-day exclusivity period.

In some circumstances, an applicant who obtains 180-day exclusivity may be the *422 sole marketer of a generic competitor to the innovator product for 180 days. But 180-day exclusivity can begin to run, with a court decision, even before an applicant has received approval for its ANDA. In that case, some, or all, of the 180-day period could expire without the ANDA applicant marketing its generic drug. Conversely, if there is no court decision and the first applicant does not begin commercial marketing of the generic drug, there may be prolonged or indefinite delays in the beginning of the first applicant’s 180-day exclusivity period. Approval of an ANDA has no effect on exclusivity, except if the sponsor begins to market the approved generic drug. Until an eligible ANDA applicant’s 180-day exclusivity period has expired, the FDA cannot approve subsequently submitted ANDAs for the same drug, even if the later ANDAs are otherwise ready for approval and the sponsors are willing to immediately begin marketing. Therefore, an ANDA applicant who is eligible for exclusivity is often in the position to delay all generic competition for the innovator product.

III. BACKGROUND

Merck is the owner of nine patents listed in the Orange Book for the drug alen-dronate sodium, which Merck markets and sells under the trademark Fosamax. 2 On February 24, 2006, Apotex sent Merck a letter informing Merck that Apotex filed ANDA No. 077-982, seeking approval from the FDA to market a generic version of Merck’s Fosomax tablets. Apotex certified in its ANDA submission that certain Merck patents were invalid, unenforceable and/or will not be infringed by the commercial manufacture, use, or sale of Apo-tex’s generic version. Apotex was not the first generic filer to challenge Merck’s patents on the Fosamax drug.
