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.
EVE issued a statement Monday denying any wrongdoing. The company said it believes the Mentor litigations are unfounded and would defend itself in court.
"Mentor Graphics’ behavior is predictable," said Luc Burgun, EVE president and CEO. "In 2006, Mentor Graphics tried to use the legal system to stifle competition when it was struggling to deliver Veloce and had concerns about EVE accelerating deployment through a line of successful products. This is yet another groundless litigation and we will vigorously defend ourselves."
