CARLSBAD, Calif., March 9 /PRNewswire-FirstCall/ -- Patriot Scientific
Corporation (OTC Bulletin Board: PTSC) confirmed today that SanDisk, the
world's largest supplier of flash storage card products, 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.
    SanDisk is the 15th 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 SanDisk
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 and Funai Electric have purchased MMP Portfolio licenses in the
past 13 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 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.
