SAN FRANCISCO—EDA vendor Mentor Graphics Corp. said Friday (Aug. 17) it filed another patent infringement suit against French emulation tool vendor EVE SA, the latest in an escalating legal battle between the two companies that has simmered for years.
Mentor (Wilsonville, Ore.) said its latest suit, filed in U.S. District Court in Oregon, alleges that EVE products violate Mentor's U.S. patent No. 6,947,882. The patent, entitled "Regionally Time Multiplexed System" was issued in September 20 2005, Mentor said.
The latest suit seeks to recover damages and to bar the manufacture and sale of the allegedly infringing products, Mentor said.
"As we continue to learn more about EVE’s products, and discover infringement of our intellectual property, we will continue to aggressively protect that intellectual property," said Tom Evans, Mentor's corporate intellectual property counsel, in a statement.
Representatives of EVE were not immediately available for comment.
Mentor has filed several intellectual property infringement suits against
EVE (Palaiseau, France) in the U.S. and Japan
over the past few years. A separate suit brought by Mentor in the U.S. in 2006 was
settled in 2007. Related stories:
