CARLSBAD, Calif., April 26 /PRNewswire-FirstCall/ -- Patriot Scientific
Corporation (OTC Bulletin Board: PTSC) 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
