Medtronic Inc. (MDT) must try again to prove that it didn’t infringe two patents controlled by Boston Scientific Corp. over implantable defibrillators, a U.S. appeals court said today. U.S. District Judge Sue Robinson in Wilmington, Delaware, erred in her analysis of the patents owned by Mirowski Family Ventures and licensed to Boston Scientific, the U.S. Court of Appeals for the Federal Circuit said in an opinion posted on its website. The judge also improperly placed the burden on Mirowski to prove infringement when it was Medtronic that filed the suit, the appeals court said.
