NEW YORK--(BUSINESS WIRE)--Pfizer Inc said today that the Federal Court of Appeal of Canada has reversed a lower court ruling that held that Pfizer’s enantiomer patent could not block generic manufacturer Ranbaxy Laboratories Limited from obtaining approval for a competitor product to Lipitor. The appellate court issued an order prohibiting regulatory approval of Ranbaxy’s product in Canada until Pfizer’s enantiomer (calcium salt) patent—Canadian Patent No. 2,021,546—expires in July 2010.
