Pronova Prevails in U.S. Lovaza® Patent Litigation


WASHINGTON, DC - The U.S. District Court for the District of Delaware ruled on May 29, 2012, in favor of Finnegan client Pronova BioPharma Norge AS in its patent litigations against Teva Pharmaceuticals USA, Inc., Par Pharmaceutical, Inc. and Par Pharmaceutical Companies, Inc. regarding their efforts to obtain FDA approval to market generic copies of Lovaza®. The District Court held that the asserted claims of U.S. Patent No. 5,656,667 and U.S. Patent No. 5,502,077 are valid and enforceable, thus maintaining patent protection for Lovaza® in the United States until at least April of 2017. The District Court also held that the proposed generic products infringe these patent claims. Lovaza® is prescribed as an adjunct to diet to reduce triglyceride levels in adult patients with severe hypertriglyceridemia, with over $900 million in U.S. sales in 2011. Pronova markets this product in the U.S. with GlaxoSmithKline, which was not a party to these litigations.

Pronova previously filed a similar action against Apotex Corp. and Apotex Inc., which the parties settled in March of 2011.
