Amphastar Announces Jury Verdict in Patent Litigation against Momenta Pharmaceuticals, Inc. and Sandoz Inc.

July 24, 2017

RANCHO CUCAMONGA, Calif., July 24, 2017 (GLOBE NEWSWIRE) -- Amphastar Pharmaceuticals, Inc. (NASDAQ:AMPH) announced today that a federal jury delivered a unanimous verdict in favor of Amphastar in a lawsuit brought by Momenta Pharmaceuticals, Inc. and Sandoz Inc. (the “Plaintiffs”) in the U.S. Court for the District of Massachusetts. The jury found the claims of Momenta’s U.S. Patent No. 7,575,886 (the “Patent”) to be invalid for lack of enablement and lack of adequate written description.  The jury further found that the Plaintiffs had waived their ability to enforce the Patent because of Plaintiffs’ conduct before the U.S. Pharmacopeia (“USP”), and that the Plaintiffs were estopped from enforcing the Patent because of this conduct.

Amphastar's CEO, Dr. Jack Zhang, stated: "We have always believed that the facts and the law do not support the Plaintiffs’ baseless allegations and we are very pleased that justice has prevailed.  We remain proud of our technology for product development and will continue to execute on our mission of developing and manufacturing life-saving drugs for the benefit of patients.”
