Patriot Scientific and TPL Announce New MMP Licenses and Support for Licensing and Litigation Efforts

Carlsbad, CA and Cupertino, CA - February 3, 2011 - Patriot Scientific Corporation (OTC Bulletin Board: PTSC News), The TPL Group, and Alliacense announced today that during December 2010 and January 2011, MMP Patent Portfolio licenses were entered into with several companies in the telecommunications and industrial equipment industry segments.

Earlier this month Patriot and TPL resolved a number of issues that arose over the past year related to the licensing and litigation activities of the MMP Patent Portfolio. The resolution included an agreement to provide a substantial increase in working capital for the MMP licensing program and patent infringement litigation from MMP licensing proceeds. The increased commitment reflects the companies' recognition of the strength and growing confidence in the MMP Portfolio based on the long string of successes in defeating multiple re-examination attacks in both the USPTO and Europe, as well as the continued pace of the MMP Licensing Program which totals over 80 world-class Licensees to date.

On January 24, 2011, Patriot dismissed the action it had filed on April 12, 2010, against TPL in San Diego Superior Court in conjunction with TPL's cash settlement of the outstanding obligation. TPL has also agreed to increased involvement of Patriot in the oversight of the MMP Portfolio activities. Talks between Patriot and TPL continue as the parties work to resolve the remaining lawsuit in Santa Clara County.
