U.S. Patent and Trademark Office confirms validity of patent for UCB's Vimpat®

  •  IPR proceedings in favor of UCB

Brussels (Belgium), 22 March 2017 – UCB announces today that the U.S. Patent and Trademark Office (USPTO) confirmed the validity of U.S. patent RE38,551 related to Vimpat® (lacosamide), UCB’s anti-epileptic drug, in the Inter Partes Review (IPR) proceedings.

In May 2016, the U.S. Patent and Trademark Office had agreed to initiate IPR proceedings, following Argentum Pharmaceuticals LLC’s Petition, to review whether the U.S. patent RE38,551 patent is invalid due to obviousness.

"We are pleased with the outcome of the IPR review," said Anna S. Richo, Executive Vice President & General Counsel at UCB. "In finding that the Petitioner failed to establish that any of the claims of the patent are unpatentable for obviousness, the USPTO’s decision further confirms, as did the Delaware District Court decision in August 2016, the strength of our intellectual property for Vimpat®."

This decision supports UCB’s commitment to epilepsy patients.

In August 2016, the U.S. Delaware District Court confirmed the validity of U.S. patent RE38,551 related to Vimpat® (lacosamide).
