Manhattan-based pharmaceutical companies Pfizer Inc. and Forest Laboratories Inc. both filed patent-infringement suits this week against manufacturers of rival drugs. Pfizer, which makes the erectile-dysfunction drug Viagra, filed suit in Delaware federal court against German firm Bayer AG and U.K. company GlaxoSmithKline Plc, which are co-marketing Levitra. The Pfizer spokesman says that this actually was a continuation of a suit filed in October; it was amended and refiled to reflect the fact that Levitra has now been approved for sale. Levitra has captured half the new prescriptions written for impotency since its launch earlier this month.
