Allergan plc a leading global pharmaceutical company, announced that the United States Court of Appeals for the Federal Circuit affirmed the United States District Court for the Eastern District of Texas' earlier decision that that each of three Allergan patents (U.S. Patent Nos. 7,030,149, 7,320,976 and 8,748,425) that are listed in the Orange Book for COMBIGAN® is valid. The Federal Circuit also affirmed the district court's finding that Sandoz' proposed generic version of COMBIGAN® does not infringe the '149 and '976 patents, and reversed the district court's decision that Sandoz' proposed generic product infringes the '425 patent.
