Patriot Scientific Welcomes Philips to List of Microprocessor Patent Licensees; Announcement Signals Increased Activity as the Patent-Infringement Trial Date Approaches

CARLSBAD, Calif.--Patriot Scientific (OTCBB:PTSC) announced today that Royal Philips Electronics has purchased a Moore Microprocessor Patent(TM) (MMP) Portfolio license. Philips becomes the 23rd MMP licensee in as many months and the third major European company to purchase a license following Schneider Electric and Nokia Corporation.

"We welcome the expansion of our program with Philips, a proven worldwide leader in medical equipment and consumer electronics. This agreement further validates the strength and broad scope of the MMP Portfolio," said Andre-Pascal Chauvin, vice president of licensing for Alliacense, Patriot Scientific Corporation's licensing partner.

"It's pretty common to see the pace of deals pick up as a trial approaches," said Mike Davis, senior vice president, licensing. "A number of major businesses that have been following the case closely needed a little time to evaluate the recent Markman ruling, and are now moving to capture licenses at current prices and avoid significantly higher royalty rates following trial."

"Other developments we're watching with interest include mounting pressure from retailers on product manufacturers to resolve patent-infringement issues expeditiously and avoid major market disruptions that could result from injunction or ban on imports," continued Davis. "This issue was highlighted recently in Broadcom v. Qualcomm ITC case, which placed a ban on the import of new mobile handsets and led Verizon Wireless to step in and resolve the matter on its own."

The sweeping scope of applications using MMP design techniques continues to encourage manufacturers of end-user products from around the globe to become MMP licensees. Since January 2006 more than twenty companies including Hewlett Packard, Sony, Casio, Fujitsu, Nikon, Seiko Epson, Pentax, Olympus, Kenwood, Agilent, Lexmark, Schneider Electric, NEC Corporation, Funai Electric, SanDisk, Sharp Corporation, Nokia, Bull, LEGO and Denso Wave have all purchased MMP Portfolio licenses.
