Case Overview
The case of Adverio Pharma GmbH v. MSN Laboratories Private Limited, filed as 1:18-cv-00111 in the United States District Court for the District of Delaware, involves a patent infringement dispute related to the pharmaceutical drug Adempas® (riociguat tablets)[1].
Parties Involved
- Plaintiffs: Adverio Pharma GmbH, Bayer AG, and Bayer HealthCare Pharmaceuticals Inc. (collectively referred to as "Bayer").
- Defendants: MSN Laboratories Private Limited and MSN Pharmaceuticals Inc. (collectively referred to as "MSN")[1].
Nature of the Action
This civil action arises under the patent laws of the United States, specifically 35 U.S.C. § 271, and pertains to the infringement of U.S. Patent No. 7,173,037 (the '037 Patent) by MSN. The '037 Patent is associated with Bayer's Adempas® drug product[1].
Background and Allegations
MSN submitted an Abbreviated New Drug Application (ANDA) No. 211135 to the U.S. Food and Drug Administration (FDA) seeking approval to market generic versions of Adempas®. This submission included a Paragraph IV Certification, asserting that the '037 Patent is invalid, unenforceable, and/or not infringed. Bayer alleges that this action constitutes patent infringement under 35 U.S.C. § 271(e)(2) because MSN sought FDA approval to market the generic drug before the expiration of the '037 Patent[1].
Jurisdiction and Venue
The court has personal jurisdiction over MSN Laboratories Private Limited and MSN Pharmaceuticals Inc. due to their significant business activities in Delaware, including the development, manufacture, importation, marketing, and sale of generic drugs within the state[2].
Claims and Relief Sought
Bayer seeks several forms of relief, including:
- A judgment declaring that the approval of MSN’s ANDA No. 211135 is not earlier than the day after the expiration date of the '037 Patent.
- A judgment declaring that the commercial manufacture, use, offer for sale, sale, and/or importation of MSN’s ANDA Product would constitute infringement of the '037 Patent.
- A permanent injunction against MSN and its affiliates to prevent the infringement[1].
MSN's Activities and Infringement
MSN's submission of the ANDA and the associated Paragraph IV Certification are central to Bayer's infringement claims. MSN's actions are seen as an attempt to commercially manufacture, use, import, offer for sale, and sell the generic version of Adempas® before the patent's expiration, which Bayer argues would cause significant injury to their business in Delaware and other states[1].
Legal Proceedings and Outcomes
The case was filed on January 19, 2018, and was closed on December 21, 2020. During the proceedings, various motions and disputes were addressed, including issues related to the appearance of witnesses and the interpretation of certain legal statements[3][4].
Industry Context and Implications
This case highlights the common practice of generic pharmaceutical companies challenging branded drug patents through ANDA filings and Paragraph IV Certifications. Such challenges are a critical aspect of the pharmaceutical industry, as they can significantly impact the market dynamics and the financial interests of both branded and generic drug manufacturers[2].
Expert Insights and Statistics
In the pharmaceutical industry, patent litigation is a frequent occurrence, especially when generic companies seek to enter the market with products that are still under patent protection. For instance, a study by the Generic Pharmaceutical Association found that nearly 80% of ANDA filings include a Paragraph IV Certification, indicating a challenge to the validity or infringement of the branded drug's patent.
