Tokyo Electron Purchases Moore Microprocessor Patent™ Portfolio License

Business Wire, Feb 5, 2008

CUPERTINO, Calif. -- Alliacense today announced that Tokyo Electron Limited (TEL) has purchased a Moore Microprocessor Patent[TM] (MMP) Portfolio license from The TPL Group. TEL manufactures and sells semiconductor and LCD production equipment, as well as computer systems.

"Tokyo Electron is the fourth MMP Portfolio licensee since TPL announced the settlement with all remaining defendants in the MMP patent infringement case in mid-December," said Rick Schuette, Vice President, 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."

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 over 30 global companies from the US, Europe, Japan, Korea and Taiwan have purchased MMP Portfolio licenses.

The MMP Portfolio patents, filed by The TPL Group in the 1980s, cover techniques that enable higher performance and lower cost designs, and are fundamental to consumer and commercial digital systems ranging from DVD players, cell phones and portable music players to communications infrastructure, medical equipment -- and automobiles which today have dozens of microprocessor-based key features and benefits.

About the MMP Portfolio

The Moore Microprocessor Patent Portfolio contains intellectual property that is jointly owned by the privately-held TPL Group and publicly-held Patriot Scientific Corporation (OTCBB: PTSC). The MMP Portfolio includes seven U.S. patents as well as their European and Japanese counterparts. It is widely recognized that the MMP Portfolio protects fundamental technology used in microprocessors, microcontrollers, digital signal processors (DSPs), embedded processors and system-on-chip (SoC) devices.
