Portion of Future Revenues Allocated for Stock Buyback

Carlsbad, CA - April 24, 2006: Patriot Scientific Corporation (OTC Bulletin Board: PTSC.OB) today announced a plan under which it would utilize 10 percent or more of future licensing revenues to buy back corporate stock. The Company also announced significant earnings results for its third fiscal quarter, as contained in its Form 10Q filed last Thursday, and confirmed that the previously announced cash dividend of $.04 per share is being issued today.

"The stock buyback plan adopted by the Board of Directors calls for management to use not less than 10 percent of future licensing revenue distributions received by the Company to purchase shares of our stock on the open market in a manner consistent with applicable securities laws and regulations," said David H. Pohl, Chairman and CEO of Patriot Scientific. "These buybacks are, of course, subject to the Company determining at the time licensing revenue distributions are received that such action is prudent based upon market conditions and sound financial management considerations. Repurchased shares will be placed in our treasury as a resource available for possible future use," Pohl explained.

"This stock buyback program reflects our confidence in both the near- and long-term prospects for Patriot Scientific," Pohl stated. "We are committed to returning value to stockholders in various ways, including through our growth strategy as well as our focus on operational excellence and ability to generate and manage strong cash flow. As we receive and accumulate cash in the future from anticipated licensing revenues, our Board will be continuing to review and update our business and strategic plans," he continued. "These considerations currently include payment of dividends, buying back some of our outstanding shares and warrants, and contemplation of other prudent and feasible ways in which we might put future cash to work to create additional streams of revenue for the benefit of the Company and our shareholders."
