Otsuka Prevails in U.S. Abilify® Patent Appeal

 

WASHINGTON, DC - The U.S. Court of Appeals for the Federal Circuit ruled today (May 7, 2012) in favor of Otsuka Pharmaceutical Co., Ltd. in its patent litigation against several companies seeking FDA approval to market generic copies of Abilify®. The Federal Circuit affirmed a decision of the U.S. District Court for the District of New Jersey holding that the asserted claims of U.S. Patent No. 5,006,528 covering aripiprazole, the active ingredient in Abilify®, are valid, thus maintaining patent and regulatory protection for Abilify® in the U.S. until at least April 20, 2015. The District Court also had held that the patent was enforceable and infringed by the proposed generic products, which issues were not appealed to the Federal Circuit. As a result of these holdings, the FDA is precluded from approving, and the respective companies are enjoined from marketing, these products in the U.S. until at least April 20, 2015. Abilify® is prescribed for schizophrenia and other mental disorders and is one of the largest selling pharmaceutical in the U.S., with over $5.2 billion in sales in 2011. Otsuka co-markets this product in the U.S. with BMS. BMS was not a party to these litigations.

The Defendants included Teva Pharmaceuticals, Barr Pharmaceuticals (now part of Teva), Sandoz, Synthon Laboratories, Sun Pharmaceuticals, Zydus Pharmaceuticals and Apotex. Finnegan's co-counsel on the case was Fitzpatrick, Cella, Harper & Scinto.
