On June 9, 2014, a federal appeals court upheld a win for W. L. Gore & Associates, Inc. (Gore) in a patent infringement case over a heart defect treatment device. The Federal Circuit affirmed an earlier district court decision that ruled in favor of Gore, maintaining that Gore did not infringe on a patent for a heart defect implant held by AGA Medical Corp., which has since been acquired by St. Jude Medical. AGA Medical sued Gore in 2010, accusing Gore of violating a patent with its Helex septal occluder.
In July 2013 the U.S. District Court for Minnesota dismissed the lawsuit, ruling that AGA failed to prove that the Helex device infringes the patent by using the court's claim construction that the patent covers the "means for securing said device to a delivery system"—specifically, that an infringing device must include a clamp with a threaded bore, according to court documents.
Gore was represented by Faegre Baker Daniels attorneys James Poradek, Jared Briant, Kevin Wagner, Nina Wang, Leslie Prill and Katherine Razavi.
