Carlsbad, Calif. -- March 9, 2007 -- 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™ (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.
