In denying cert to Abbvie Inc. v. FTC June 21, the U.S. Supreme Court may have strengthened an FTC tool for going after biopharma companies that try to protect their patents. The high court’s refusal to hear the case reinforces a September decision by the U.S. Court of Appeals for the Third Circuit that the biopharma industry has said will make it more difficult for drug companies to pursue patent infringement cases in keeping with Hatch-Waxman.
