Pfizer Inc. said Monday a federal court has backed its patent protecting the erectile dysfunction drug Viagra, which prevents generic drugmaker Teva Pharmaceuticals USA Inc. from receiving approval for its version of the drug until October 2019.
Pfizer, the world's largest drugmaker, said the decision by the U.S. District Court for the Eastern District of Virginia is subject to appeal.
The company also said litigation on the same patent is still pending against other companies.
The New York-based Pfizer is one of southeastern Connecticut's largest employers, with campuses in Groton and New London.
