  Greatbatch Files Patent Infringement Complaint Against AVX in Federal Court

Business Wire

FRISCO, Texas -- April 26, 2013

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.”
