               Patriot Scientific Announces Major Patent Licensing
                         Agreement with Hewlett-Packard

HP joins Intel and AMD as early licensees of MMP Portfolio, validating need for
   system manufacturers to license fundamental microprocessor design patents

San Diego, Calif. - January 24, 2006 - Patriot Scientific Corporation (OTCBB:
PTSC.OB) today announced that Hewlett-Packard (HP) has become the first system
manufacturer to purchase a license to use intellectual property protected by the
Moore Microprocessor Patent(TM) (MMP) Portfolio. Patriot is a co-owner of the
MMP Portfolio as a result of an agreement reached between Patriot and The TPL
Group in June 2005. The portfolio is being exclusively managed by Alliacense, a
TPL Group enterprise.

Following the previous purchases of MMP Portfolio licenses by marquee chip
makers Intel and AMD in 2005, the MMP Portfolio Licensing Program has been tuned
to also serve leading manufacturers of computer, communications and
entertainment systems. Specific terms of the license purchased by HP were not
disclosed.

"This is a highly significant milestone for Patriot Scientific," said Patriot
Chairman and CEO David Pohl. "This new license agreement with HP helps to
confirm the significance of the patents in our valuable jointly owned portfolio.
It is a major step in demonstrating to our shareholders that the decision of
Patriot's Board of Directors and new management to proceed with the PTSC/TPL
alliance was a prudent business decision," Pohl added. "We are pleased that our
faith in the professionalism and abilities of the Alliacense licensing team was
well placed, and we know that discussions are well under way with dozens of
other major system manufacturers around the world."

"Today's consumer electronics and computer systems each incorporate an
increasing number of microprocessors that exploit the techniques protected by
the MMP Portfolio," stated Mac Leckrone, Alliacense president. "We are very
pleased to witness a globally respected system manufacturer confirm our MMP
Portfolio Licensing Program strategy. We have believed from the outset that the
most attractive path for equipment makers was to purchase a single MMP System
License that covers an entire system or end-user product."

Last October, The TPL Group, in the process of managing and prosecuting the
patent portfolio jointly owned with Patriot Scientific, filed a broad-based
intellectual property claim against four major Japanese electronics system
manufacturers in the US District Court, Eastern District of Texas. The
broad-based claim cited Fujitsu, Matsushita, NEC and Toshiba for direct
infringement, contributory infringement, and inducing the infringement of at
least three of the ten patents in the Moore Microprocessor Patent(TM) (MMP)
Portfolio, specifically:

      o     U.S. 5,784,584: Multiple Instruction Fetch
      o     U.S. 5,809,336: Clocking CPU and I/O Separately
      o     U.S. 6,598,148: Use of Multiple Cores and Embedded Memory

The cited infringement pertains to a wide variety of end-user products including
personal computers, servers, workstations, printers, routers, home theater
systems, digital TVs, video game players, DVD Recorders/Players, mobile
handsets, portable media players, automotive and aircraft/aerospace electronics,
and most other modern microprocessor-based products. The MMP Portfolio, which
encompasses US, European and Japanese patents, is protected through the year
2015. Global sales of end products deploying chips using technologies protected
by these jointly held patents are estimated to be greater than $200 billion
annually.
