Innoviva, Inc. 10-Q

Item 1. Legal Proceedings As previously disclosed in the Quarterly Report on Form 10-Q filed by La Jolla on August 15, 2022, on February 15, 2022, La Jolla received a paragraph IV notice of certification (the “First Notice Letter”) from Gland Pharma Limited (“Gland”) advising that Gland had submitted an Abbreviated New Drug Application (“ANDA”) to the FDA seeking approval to manufacture, use or sell a generic version of GIAPREZA ® in the U.S. prior to the expiration of U.S. Patent Nos.: 9,220,745; 9,572,856; 9,867,863; 10,028,995; 10,335,451; 10,493,124; 10,500,247; 10,548,943; 11,096,983; and 11,219,662 (the “GIAPREZA ® Patents”), which are listed in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations (the “Orange Book”). The First Notice Letter alleges that the GIAPREZA ® Patents are invalid, unenforceable and/or will not be infringed by the commercial manufacture, use or sale of the generic product described in Gland’s ANDA. On March 29, 2022, La Jolla filed a complaint for patent infringement of the GIAPREZA ® Patents against Gland and certain related entities in the United States District Court for the District of New Jersey in response to Gland’s ANDA filing. In accordance with the Hatch-Waxman Act, because GIAPREZA ® is a new chemical entity and La Jolla filed a complaint for patent infringement within 45 days of receipt of the First Notice Letter, the FDA cannot approve Gland’s ANDA any earlier than 7.5 years from the approval of the GIAPREZA ® NDA unless the District Court finds that all of the asserted claims of the patents-in-suit are invalid, unenforceable and/or not infringed. 48 On February 22, 2023, La Jolla received a paragraph IV notice of certification (the “Second Notice Letter”) from Gland advising that Gland had amended its ANDA filing to include a paragraph IV certification alleging that all claims of the newly-issued and Orange Book-listed U.S. Patent No. 11,559,559 (“the ’559 Patent”), which covers GIAPREZA ® , are invalid, unenforceable and/or not infringed. On March 22, 2023, La Jolla filed a First Amended Complaint in this litigation adding Gland’s marketing and distribution partners for its ANDA angiotensin II product, Fresenius Kabi USA LLC and Fresenius Kabi SwissBiosim GmbH, as co-defendants. On April 7, 2023, La Jolla filed a Second Amended Complaint in response to the Second Notice Letter, adding claims that the manufacture, use, sale, offer for sale, or import of Gland’s ANDA angiotensin II product will infringe the ’559 Patent. We intend to vigorously enforce our intellectual property rights relating to GIAPREZA ® .
