Warner Chilcott, PLC Sues Watson Pharmaceuticals, Inc. Over Generic Contraceptive

Warner Chilcott Plc (WCRX), the maker of dermatology and women’s health drugs, sued Watson Pharmaceuticals Inc. (WPI) to prevent it from selling a generic version of its oral contraceptive Lo Loestrin Fe. Watson is seeking U.S. Food and Drug Administration approval to sell a copy of the low-dose contraceptive, according to a complaint filed yesterday in federal court in Trenton, New Jersey. Dublin-based Warner Chilcott said the Watson version would infringe two patents and seeks a court order to prevent sales until patents expire in July 2014 and February 2029.
