Background of the Litigation
The litigation between Supernus Pharmaceuticals, Inc. and Zydus Pharmaceuticals (USA) Inc. revolves around the patent rights for Trokendi XR®, an antiepileptic drug developed by Supernus. The dispute began when Zydus filed an Abbreviated New Drug Application (ANDA) with the FDA to market a generic version of Trokendi XR®[2][5].
Initial Lawsuit and Patent Infringement Claims
In 2014, Supernus Pharmaceuticals filed a lawsuit against Zydus Pharmaceuticals in the U.S. District Court for the District of New Jersey, alleging patent infringement. The lawsuit claimed that Zydus's ANDA filing infringed on Supernus's patents covering Trokendi XR®[3][5].
Settlement Agreement of 2017
Before the trial, the parties reached a settlement agreement on March 6, 2017. This agreement allowed Zydus to begin selling a generic version of Trokendi XR® on January 1, 2023, or earlier under certain circumstances. Despite this settlement, Supernus continued to enforce its patent rights vigorously[1].
Pending Litigation and 30-Month Stay
The settlement did not resolve all issues, and the litigation continued. Zydus's ANDA No. 216167 was subject to a 30-month stay of FDA approval, which was set to expire on February 6, 2024. The trial for the pending litigation was scheduled to begin on November 7, 2023[2].
2022 Settlement Agreement
On December 31, 2022, Supernus and Zydus entered into another settlement agreement to resolve the pending litigation. This agreement included several key terms:
- Zydus admitted the validity and enforceability of Supernus's patents related to Trokendi XR®.
- Zydus acknowledged that its ANDA filing and the manufacture, use, sale, or importation of the generic product would infringe Supernus's patents without a license.
- The parties agreed to release and discharge each other from any claims related to the litigated patents[2].
Terms and Conditions of the 2022 Settlement
The 2022 settlement included a license agreement for the Zydus 200 mg product. Key terms included:
- Zydus's admission of patent infringement.
- The parties' consent to the jurisdiction of the court.
- A mutual release of claims related to the litigated patents.
- The agreement did not preclude Zydus from asserting counterclaims or defenses of invalidity or non-infringement in future proceedings[2].
