CARLSBAD, Calif., April 11 /PRNewswire-FirstCall/ -- Patriot Scientific
Corporation (OTC Bulletin Board: PTSC) confirmed today that Sharp
Corporation has purchased a Moore Microprocessor Patent(TM) (MMP) Portfolio
license. Patriot Scientific and The TPL Group are co-owners of the MMP
Portfolio, which Alliacense, a TPL Group enterprise, exclusively manages.
    Sharp is the 16th company to join the distinguished roster of global
manufacturers that have captured early-mover MMP licensing berths in
specific industry segments since January 2006. Alliacense again confirmed
that subsequent licensees in segments where early tiers have been secured
are subject to progressively higher royalty rates on relevant products.
    The intellectual property assets protected by the MMP Portfolio
encompass fundamental design techniques that enable higher performance and
lower cost digital electronic systems ranging from cell phones and portable
music players to communications infrastructure and medical equipment as
well as automobiles, which today utilize dozens of microprocessors.
    "As a co-owner of the MMP Portfolio we are pleased to welcome Sharp to
the growing family of companies participating in the MMP Portfolio
Licensing Program," said David Pohl, chairman and CEO of Patriot Scientific
Corporation. He noted that HP, Casio, Fujitsu, Sony, Nikon, Seiko Epson,
Pentax, Olympus, Kenwood, Agilent, Lexmark, Schneider Electric, NEC
Corporation, Funai Electric and SanDisk have purchased MMP Portfolio
licenses in the past 14 months. Intel and AMD are also licensees.
    Pohl noted that the strong momentum of the licensing program validates
the decision by Patriot's board of directors in June 2005 to shift the
company's primary business model from manufacturing and marketing products
to a model currently focused primarily but not exclusively on licensing
their joint venture MMP patent portfolio. He emphasized that Patriot
Scientific invested millions of dollars and hundreds of thousands of
man-hours over 12 years or more developing and bringing to market products
based upon the company's intellectual property, including IP contained in
the MMP Portfolio.
    "We will continue to seek and evaluate opportunities to diversify our
revenue stream by developing and marketing new technologies, entering into
joint ventures or by acquiring other companies and technologies," Pohl
stated, "always pointed toward the goal of increasing the financial
position and strength of the company and providing value to our
shareholders."
