ROCKAWAY, N.J. Pharmaceutical company Warner Chilcott has filed a lawsuit against Barr Pharmaceuticals Inc. for patent infringement, according to the Associated Press.

The company, which produces pharmaceuticals mainly for women’s health and dermatology, said the lawsuit is in response to Barr's application with the Food and Drug Administration for a generic version of the contraceptive Femcon FE. Warner Chilcott's patent doesn't expire until 2019.

Barr's application for FDA approval will be on hold for 30 months because of the lawsuit filing.
