Europe Spikes Edwards Lifesciences Corporation' TAVI Patent In War With Medtronic, Inc.

The European Patent Office revokes an Edwards Lifesciences transcatheter aortic valve patent that has been the center of a long-running feud with Medtronic. Medtech titan Medtronic (NYSE:MDT) landed a major win against arch-rival Edwards Lifesciences (NYSE:EW) when the European Patent Office revoked an Edwards patent at the heart of a contentious infringement lawsuit. The EPO decision stymies Edwards' efforts to keep Medtronic's CoreValve transcatheter aortic valve implantation system off the market, but doesn't affect Edwards' own sales.
