Patriot Scientific CEO David Pohl to Retire

CARLSBAD, Calif. -- April 26, 2007 -- Patriot Scientific Corporation today announced that Chairman and CEO David H. Pohl has notified them of his intent to retire from the position of chief executive officer as soon as a new CEO is appointed. He will continue to serve as chairman of the board.

"I decided that my 70th birthday in June would be a good time to step aside from daily business operations and let someone else take the wheel," Pohl stated. "With that in mind, I informed the board of directors of my intent last February. Since that time the board has been identifying and considering various candidates for the position."

The search for a new candidate is being spearheaded by Carlton M. Johnson Jr., chairman of the executive committee of the Patriot Scientific Board of Directors. "The board appreciates the fine job David has done while serving as our CEO," said Johnson. "We have asked him to continue to serve as our chairman and we are delighted that he has agreed."

Pohl was named chairman and CEO in June 2005. At that time the company replaced its former management team and embarked upon a new strategic alliance in a joint venture with The TPL Group to commercialize their jointly owned MMP Portfolio patent portfolio. The MMP Portfolio patents protect design techniques that have become essential to myriad consumer and commercial digital systems ranging from computers, DVD players, cell phones and portable music players, to communications infrastructure, medical equipment and automobiles. Sixteen major electronics manufacturers have signed licenses since January of 2006 to utilize technology covered by one or more patents in the portfolio.

"I am passionate about Patriot Scientific and its potential for the future, and nothing on the horizon dims my positive outlook," said Pohl. "I believe that a publicly held company like Patriot Scientific, with a wide base of shareholders, millions of dollars in the bank and no long-term debt is wonderfully poised to create and take advantage of some terrific business opportunities in its future, in addition to capitalizing on licensing its valuable patent portfolio."

"It has been an honor to serve in this important position while Patriot Scientific has progressed through this critical transition in its corporate history," he continued. "I am looking forward to continuing to help shape the future of this great company in my ongoing role as chairman while a new dynamic CEO steps into place to contribute his experience, energy and vision toward creating increased value for our shareholders," Pohl concluded.

Patriot Scientific will hold its annual meeting of shareholders Friday, April 27, 2007 at the La Costa Resort and Spa in Carlsbad, California. Proxy statements were mailed to shareholders April 9, 2007. Further information is available on the company's web site at http://www.ptsc.com.
