Introduction
In the complex and highly regulated pharmaceutical industry, patent disputes are commonplace. One such dispute is the litigation between Merz Pharmaceuticals, LLC and MSN Pharmaceuticals Inc., which revolves around the generic version of Merz's drug Cuvposa. Here is a detailed summary and analysis of this litigation.
Background of the Case
Merz Pharmaceuticals, LLC, the holder of the New Drug Application (NDA) for Cuvposa, a glycopyrrolate oral solution used to treat ulcers and prevent drooling in young patients and those with conditions that cause drooling, initiated this lawsuit. The dispute arose when MSN Pharmaceuticals Inc. submitted an Abbreviated New Drug Application (ANDA) to the Food and Drug Administration (FDA) to manufacture a generic version of Cuvposa[1].
The Hatch-Waxman Act and ANDA Filings
The Hatch-Waxman Act sets the procedural framework for the regulatory approval and commercial marketing of pharmaceuticals, including generic drugs. Under this act, each ANDA must include a certification or statement for each patent listed in the Orange Book. MSN Pharmaceuticals cited paragraph IV of 21 U.S.C. Sec. 355(j)(2)(a)(vii), asserting that the patent is not valid or will not be infringed by the new drug[1].
Merz Pharmaceuticals' Claims
Merz Pharmaceuticals alleged that MSN's ANDA filing was dishonest and made solely for the purpose of infringing Merz's patent. Merz argued that MSN's generic version directly infringes upon claims within its patent and that MSN had no reason to believe otherwise. Merz also claimed that MSN’s product has no non-infringing uses and that the intent to manufacture, offer for sale, sell, distribute, and/or import the generic version would cause substantial and irreparable harm to Merz[1].
Legal Actions and Requests
Merz Pharmaceuticals requested that the court affirm its accusation of infringement and issue an injunction to prevent MSN, and all persons acting in concert with MSN, from the commercial manufacture, use, sale, offer for sale, or importation into the United States of MSN’s ANDA products or any other drug product covered by the patent. Merz is represented by McCarter & English LLP[1].
Court Proceedings and Jurisdiction
The lawsuit was filed in the District of New Jersey on July 16, 2021, and is identified as case number 2:21-cv-13731. The court proceedings involve detailed legal arguments and evidence submissions to support the claims of patent infringement and the potential harm to Merz Pharmaceuticals[2].
Key Issues and Arguments
- Patent Validity and Infringement: The central issue is whether MSN's generic version of Cuvposa infringes Merz's patent. Merz argues that the generic version directly infringes its patent claims, while MSN asserts that the patent is either invalid or not infringed.
- Intent and Dishonesty: Merz claims that MSN's ANDA filing was made with the intent to infringe the patent, which MSN denies.
- Irreparable Harm: Merz argues that allowing MSN to proceed with the generic version would cause substantial and irreparable harm to its business.
