Minnesota’s AGA Medical says W.L. Gore infringes patent

AGA Medical Holdings Inc. (NASDAQ: AGAM) filed a lawsuit against W.L. Gore & Associates alleging that the Newark, Del.-based company is infringing on a patent for its transcatheter occlusion device for heart defect treatment.

AGA Medical Holdings Inc. (NASDAQ: AGAM) filed a lawsuit against W.L. Gore & Associates alleging that the Newark, Del.-based company is infringing on a patent for its transcatheter occlusion device for heart defect treatment.

In a lawsuit filed in the U.S. District Court for Minnesota, AGA Medical alleges that Gore’s Helex Septal Occluder device employs technology covered by five claims in its patent for “Percutaneous Catheter Directed Constructing Occlusion Device.”

The Plymouth, Minnesota-based cardiac and vascular device maker said it wants a jury to decide whether Gore‘s device infringes the patent, a permanent injunction barring further infringement and damages.

In June, a German court awarded AGA Medical €2.1 million, or roughly $2.6 million, in a patent infringement spat with Occlutech GmbH over intravascular occlusion devices and the method of manufacturing those devices.
