A U.S. District Court judge Thursday (May 12) issued an order preventing Renesas Technology Inc. from selling in the U.S. microprocessors that have been found to infringe on a patent held by Translogic Technology Inc.
The order, issued by U.S. District Court Judge Owen Panner, prohibits Hitachi Ltd. and Renesas from selling or importing into the U.S. 18 different microprocessors found in Renesas' SH-3 and SH-4 product families.
SH-3 and SH-4 microprocessors were originally marketed by Hitachi before the spin-off of its semiconductor business, which became Renesas. While the order pertains to both companies, only Renesas currently markets the devices in the U.S.
On May 6, a jury in a U.S. court awarded Translogic $85.6 million in damages after a prior ruling that the microprocessors infringe on Translogic's transmission gate series multiplexer patent. Hitachi denied violating the patent and vowed to fight the award.
In Thursday's order, Panner said he was satisfied that Hitachi and Renesas have been infringing Translogic's patent since at least 1996.
At the request of Hitachi, the U.S. Patent and Trademark Office has been reexamining the transmission gate series multiplexer patent since June 1999.
