Greatbatch Files Patent Infringement Complaint Against AVX in Federal Court

FRISCO, Texas--(BUSINESS WIRE)-- Greatbatch Ltd., a wholly owned subsidiary of Greatbatch Inc., has filed a complaint in the U.S. District Court for the District of Delaware against AVX Corporation and AVX Filter Corporation. The complaint alleges that AVX has infringed a Greatbatch patent by manufacturing and selling filtered feedthrough assemblies used in implantable pacemakers and cardioverter defibrillators that incorporate its patented technology.

US Patent 5,905,627 was issued to Richard Brendel and Robert Stevenson for an invention entitled Internally Grounded Feedthrough Filter Capacitor. The invention shields and decouples the terminal pins in implantable medical devices to prevent interference from externally generated electromagnetic fields from devices such as mobile phones. Greatbatch took ownership of key patents in this field when the company acquired Maxwell Electronics Group Inc. of Carson City, Nevada in 2001.

Greatbatch is seeking undisclosed damages for lost profits and legal costs and an injunction against AVX prohibiting the infringement of Greatbatch patents and the misuse of the company's intellectual property.

"Greatbatch takes seriously what it believes to be willful and deliberate patent infringement," said Timothy McEvoy, vice president and general counsel at Greatbatch, Inc. "We will take all steps necessary to ensure that our intellectual property is protected."
