Pfizer wins lawsuit over Viagra patent

NEW YORK The Canadian Federal Court has decided that Apotex’s proposed generic version of the erectile dysfunction drug Viagra will infringe on one of Pfizer’s patents on the brand name drug.

The court has granted Pfizer’s request for an order to prevent Apotex from launching the generic version until the patent expires in 2014.

Apotex plans on appealing the ruling, which could take up to a year.
