Introduction
The litigation between Currax Pharmaceuticals LLC and MSN Laboratories Private Limited, along with its subsidiary MSN Pharmaceuticals Inc., is a significant case in the realm of pharmaceutical patent law. This dispute revolves around allegations of patent infringement related to generic drug products.
Nature of the Action
This lawsuit is an action for patent infringement under the patent laws of the United States, specifically Title 35 of the United States Code. Currax Pharmaceuticals LLC (Currax) alleges that MSN Laboratories Private Limited (MSN Laboratories) and MSN Pharmaceuticals Inc. (MSN Pharmaceuticals) have infringed upon its patents through the submission of Abbreviated New Drug Applications (ANDAs) to the FDA[1][2].
Parties Involved
- Currax Pharmaceuticals LLC: A corporation organized under the laws of the State of Delaware, with its principal place of business in Morristown, New Jersey.
- MSN Laboratories Private Limited: A private limited company organized under the laws of India, with its principal place of business in Hyderabad, India.
- MSN Pharmaceuticals Inc.: A wholly owned subsidiary of MSN Laboratories, incorporated under the laws of the State of Delaware[1][2].
Jurisdiction and Venue
The court has subject matter jurisdiction over this action pursuant to 28 U.S.C. §§ 1331, 1338(a), 2201, and 2202. Personal jurisdiction over MSN Laboratories and MSN Pharmaceuticals is established due to their systematic and continuous business contacts within the State of Delaware. MSN Laboratories and its subsidiary have purposefully availed themselves of the benefits and protections of Delaware’s laws, making it reasonable for them to anticipate being haled into court in Delaware[1][2].
Patent Infringement Claims
Currax alleges that MSN Laboratories and MSN Pharmaceuticals infringed upon two of its patents: the ’307 patent and the ’814 patent.
Infringement of the ’307 Patent
- MSN submitted an ANDA to the FDA to obtain approval for the manufacture, use, offer for sale, sale, and/or importation of its products in the United States, which Currax claims constitutes an act of infringement under 35 U.S.C. § 271(e)(2)(A)[1].
- Currax believes that MSN’s activities will infringe one or more claims of the ’307 patent upon FDA approval and subsequent market entry.
Infringement of the ’814 Patent
- Similar to the ’307 patent, Currax alleges that MSN’s submission of an ANDA for approval to manufacture, use, offer for sale, sell, and/or import its products in the United States will infringe the ’814 patent under 35 U.S.C. § 271(e)(2)(A) and § 271(b)[1].
MSN’s Activities and Intentions
MSN Laboratories and MSN Pharmaceuticals acted in concert to prepare and submit the ANDA to the FDA. Upon FDA approval, they intend to manufacture, market, sell, and distribute the generic products throughout the United States, including in Delaware[2].
Legal Arguments and Evidence
The case involves detailed legal arguments regarding the nature of the generic products and whether they infringe on Currax’s patents. For instance, in a related context, MSN has argued in other cases that their products do not contain amorphous forms of certain compounds, which are protected by the patents of other pharmaceutical companies. This is exemplified in the Novartis case, where MSN presented testing data to the FDA to demonstrate that their product was a crystalline compound rather than a physical mixture or amorphous form[3].
Consequences and Implications
If Currax prevails, MSN Laboratories and MSN Pharmaceuticals could face significant legal and financial consequences, including injunctions against the manufacture, sale, and distribution of the infringing products. This would protect Currax’s intellectual property rights and maintain its market position.

This litigation is part of a broader landscape of patent disputes in the pharmaceutical industry, particularly involving generic drug manufacturers. Companies like MSN Laboratories frequently engage in patent litigation as part of their business strategy to enter the market with generic versions of branded drugs. The outcome of such cases can have substantial implications for the industry, affecting market competition, drug prices, and patient access to medications[5].
