Litigation row grows at Mentor
Richard Ball A war of words is brewing in the design automation world over Quickturn’s patent litigation against Mentor Graphics. Mentor executives believe Quickturn’s new owner, Cadence Design Systems, will settle the lawsuits out of court rather than waste more money. Cadence disagrees, and avows to continue the court battles to the bloody end. “We’ve been in litigation with Quickturn for two and a half years, and between us we’re spending over a million dollars a month on lawyers,” Wally Rhines, president and CEO of Mentor, told Electronics Weekly. “Jack Harding [Cadence’s CEO] is a reasonable man. I think Jack will want to get rid of the litigation and get back to making money. Ultimately we will settle this. Cadence will want to resolve this quickly,” he said. However, Cadence told Electronics Weekly a different story. “As far as we know, this case will proceed to trial,” said Smith McKeithen, Cadence’s chief lawyer. “We haven’t seen anything that indicates a settlement.” Quickturn, and hence Cadence, are aiming to have Mentor banned from selling emulation tools. “Cadence will push to stop Mentor selling emulation products anywhere in the world,” said McKeithen. Quickturn and Mentor have been suing each other for alleged patent infringement for over two years. As a result of previous court encounters, Mentor is barred from selling its emulator products in the US.
