Item 1. Legal Proceedings
From time to time, we may be a party or subject to legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business. Some of these proceedings that we may be involved in the future, are claims that are subject to substantial uncertainties and unascertainable damages or other remedies.
Our threshold for disclosing material environmental legal proceedings involving a government authority where potential monetary sanctions are involved is $1.0 million.
In June 2022, we received a notice letter regarding an ANDA submitted to the FDA by Annora, requesting approval to market a generic version of TAVALISSE. The notice letter included a Paragraph IV certification with respect to our US Patent Nos. 7,449,458; 8,263,122; 8,652,492; 8,771,648 and 8,951,504, which are listed in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations (referred to as the “Orange Book”). The notice letter asserts that these patents will not be infringed by Annora’s proposed product, are invalid and/or are unenforceable. Annora’s notice letter does not provide a Paragraph IV certification against our other patents listed in the Orange Book. On July 25, 2022, we filed a lawsuit in the US District Court for the District of New Jersey against Annora and its affiliates, Hetero Labs Ltd., and Hetero USA, Inc., for infringement of our US patents identified in Annora’s Paragraph IV certification. On September 21, 2022, Annora and its affiliates answered and counterclaimed for declaratory judgment of non-infringement and invalidity of the ’458, ’122, ’492, ’648, and ’504 patents. We served an answer to Annora’s counterclaims in October 2022. Annora served invalidity and non-infringement contentions in December 2022. We served an answer to Annora’s invalidity and non-infringement contentions in March 2023.
As reported in our Form 10-Q for the first quarter of 2025, in March 2025, we entered into a settlement agreement with Annora resolving patent litigation related to our product TAVALISSE. Under the terms of the settlement agreement, Annora will have a license to sell its generic product in the second quarter of 2032 or earlier under certain circumstances. In accordance with the settlement agreement, the parties terminated all ongoing litigation between us and Annora regarding TAVALISSE patents pending in New Jersey as of March 26, 2025.
