| Printer friendly version
(March 6, 2014) Medtronic, Inc. announced in a press release that the European Patent Office (EPO) has invalidated European Patent Number EP2055266B1 (“the ’266 Patent”) assigned to Edwards Lifesciences PVT, Inc. The ’266 Patent, entitled “Implantable Prosthetic Valve,” states that the invention “relates to a valve prosthesis for cardiac implantation or for implantation in other body ducts.” Figure 1 of the ’266 patent is illustrated below:
According to the press release, the ’266 Patent was the basis for an August 26, 2013 injunction prohibiting sales of Medtronic’s CoreValve® System in Germany. The EPO stated that the oral proceedings resulted in “[t]he European patent [being] revoked because at least one ground for opposition prejudices the maintenance of the European patent.” The EPO file is available here.
