Tokyo Electron Purchases Microprocessor Patent Portfolio License

CARLSBAD, Calif.--(BUSINESS WIRE)--Patriot Scientific Corporation (OTCBB:PTSC) announced today Tokyo Electron Limited (TEL) has purchased a Moore Microprocessor Patent™ (MMP) Portfolio license from The TPL Group, Patriot’s exclusive licensing partner. TEL manufactures and sells semiconductor and LCD production equipment, as well as computer systems.

“Tokyo Electron is the fourth MMP Portfolio licensee since we announced the settlement with all remaining defendants in the MMP patent infringement case in mid-December,” said Rick Schuette, vice president of intellectual property for Alliacense. “The momentum of our licensing program is definitely accelerating as companies weigh those benefits versus the possibility of supply-chain disruptions.”

“I’m pleased to see Tokyo Electron join the ranks of our patent licensees,” said Jim Turley, CEO of Patriot Scientific. “It’s gratifying to know that this microprocessor technology is so useful and so widespread.”

The sweeping scope of applications using MMP Portfolio design techniques continues to encourage the world’s leading manufacturers of end-user products from around the globe to become MMP Portfolio licensees. Since January 2006 more than 30 global companies from the U.S., Europe, Japan, Korea and Taiwan have purchased MMP Portfolio licenses.
