Pfizer wins Viagra patent battle against Teva (Reuters)

BOSTON (Reuters) ? Pfizer Inc said on Monday it won a patent infringement case against the U.S. unit of Teva Pharmaceuticals Industries Ltd, preventing Teva from launching a generic version of Pfizer's erectile dysfunction drug Viagra until October 2019.

Pfizer, the world's biggest drugmaker, said litigation on the same patent remains pending against other generic companies, but no trials are scheduled in those cases.
