Barr Pharmaceuticals Inc. said that its subsidiary, Duramed Pharmaceuticals Inc. has filed lawsuits against Watson Pharmaceuticals and Sandoz, a subsidiary of Novartis, for alleged infringement of the patent covering Duramed’s Seasonale birth control pills. The suits were filed in the U.S. District Court for the District of New Jersey.
In September, the U.S. Patent and Trademark Office reissued Duramed’s patent for Seasonale. Barr, based in Montvale, N.J., has major operations in Rockland County.
“We will pursue all means to enforce the patent covering our Seasonale extended-cycle oral contraceptive, which was reissued by the (patent office) in September,” Bruce L. Downey, Barr’s Chairman and chief executive officer said in a written statement.
