Medtronic Wins Longstanding Patent Suit

U.S. District Judge Sue Robinson ruled Wednesday that two of Medtronic's implantable defibrillators do not infringe on patents licensed to Boston Scientific.

Fridley-based Medtronic, Inc., on Wednesday won a longstanding patent dispute involving two of its implantable defibrillators.

In the suit, filed in 2007 in U.S. District Court in Delaware, Medtronic claimed that its devices did not infringe on two patents that were licensed to Natick, Massachusetts-based Boston Scientific Corporation by Mirowski Family Ventures, LLC. Those patents expired in 2009.

U.S. District Judge Sue Robinson ruled in Medtronic's favor on Wednesday, saying that the company's implantable defibrillators did not infringe on the patents licensed to Boston Scientific and subsidiary Guidant Corporation.

In addition to claiming that its devices did not infringe on the two patents, Medtronic also requested that the court find the Boston Scientific patents invalid. Judge Robinson denied that request.

Medtronic is the state's seventh-largest public company and second-largest publicly traded medical device manufacturer based on revenue, which totaled $15.8 billion in its most recently completed fiscal year.
