    Patriot Scientific Corporation Announces Unprecedented Microcap Dividend

San Diego,  Calif.  -- February  14, 2006 -- In a move  virtually  unprecedented
among Microcap  stocks,  Patriot  Scientific  Corporation  (OTC Bulletin  Board:
PTSC),  a  high-tech   intellectual   properties  company  that  specializes  in
developing  and  licensing   high-performance   ultra-low  power  microprocessor
technology,  today  announced  that it will issue a cash  dividend  of $0.02 per
share of common stock for shareholders  and qualified  warrant holders of record
as of February 24, 2006. The dividend is payable March 22, 2006.

This  dramatic  announcement  follows  closely  on the  heels  of the  company's
announcement last week of a buy-back program for up to 20 million stock warrants
and  the  conversion  and  retirement  of  all  outstanding  debentures.   Final
information  as to the number of  shareholders  and  outstanding  shares will be
provided by the company's  transfer  agent as of the record date, but based upon
current   information  and  estimates  the  company  will  set  aside  funds  of
approximately  $7 million or more for payment of the dividend from its currently
available cash and cash equivalents that amount to approximately $17 million.

This announcement is especially  significant,  because until less than 12 months
ago  Patriot  had  never  shown  a  quarterly  profit  and  had  never  realized
significant  revenue  from its  10-patent  portfolio  of seminal  microprocessor
innovations.  Since  February of last year,  the company's  jointly owned patent
portfolio has been  successfully  licensed to Intel,  HP and AMD, in the process
generating  nearly $24 million in revenue for Patriot.  Based on these  licenses
and  other key  factors  covered  in  recent  SEC  filings,  Patriot  Scientific
currently has a market cap of approximately $64 million dollars.

With these successful license  negotiations as precedent,  the company,  through
its marketing alliance with The TPL Group's Alliacense division, is actively and
confidently negotiating for licenses with other U.S. and foreign companies whose
products include high speed microprocessors,  more than 150 of which were put on
notice of likely  infringement,  including  practically every high-tech consumer
electronics manufacturer and systems integrator in the global marketplace.

"We are pleased to be in the strong financial  position that enables us to offer
our loyal shareholders this significant  dividend," said David H. Pohl, Chairman
and  CEO of  Patriot  Scientific.  "The  company  strongly  believes  that  more
licensing  deals and related  revenues are likely,  although  none are assured,"
Pohl  continued.  "Patriot  Scientific's  board of directors  will  consider and
decide  whether to take such dividend  payment  actions in the future,  based on
future  revenues and the financial  condition of the company,  as well as market
conditions and other factors."

Pohl also  said  that,  "This  dividend  payment,  which is rare in the arena of
microcap  companies,   is  another  important  step  toward  evidencing  Patriot
Scientific's  current  financial  strength  and the  fact  that  the  board  and
management firmly believe in the company's future potential.  During the past 12
months,  the  company  has  undergone  significant  changes  in  management  and
operating  strategy.  As a result of those  changes and the  licensing  revenues
related to our jointly owned patent  portfolio,  we are now in a favorable  cash
position,  and we are using some of that cash to pay out our first-ever dividend
to shareholders."



The action by Patriot  Scientific to issue this  dividend,  and also last week's
decision  to  retire  the  debentures  and buy back what  could  amount to up to
approximately  20 percent of the company's total  outstanding  stock warrants at
this juncture,  were driven by the same impetus that has guided other  strategic
re-organizational  moves that began in 2005.  Last year the company changed both
its executive team and the company's strategic direction,  including the signing
of a significant  agreement  with The TPL Group  regarding  joint  ownership and
marketing of its patent portfolio.

Patriot  Scientific  received  licensing  revenues of $13  million in 2005.  The
company received distribution of an additional $10 million in January of 2006 as
a result  of a  license  transaction  with  systems  manufacturer  HP  regarding
Patriot's jointly owned patent portfolio.

"The  far-reaching  changes in 2005 helped pave the way for new  growth-oriented
initiatives  in 2006," Pohl said.  "These  changes are positive for Patriot.  We
continue to move forward with the paramount goal of enhancing  shareholder value
by prudently addressing company fundamentals and growing the business."

About the Patent Portfolio

The patent portfolio, also marketed as the MMP portfolio,  contains intellectual
property  that  became  jointly  owned  by  publicly  held  Patriot   Scientific
Corporation  and the  privately  held TPL Group in a settlement  between them in
June 2005.  Both TPL and Patriot  assert that their  jointly  owned patents have
long been  essential to the design of advanced  microprocessors,  digital signal
processors,  embedded processors and system-on-chip devices. Global sales of end
products  deploying  chips using  technologies  protected  by the jointly  owned
patents  are  estimated  to be  greater  than  $200  billion  annually.  The MMP
Portfolio is exclusively  managed by Alliacense,  a TPL Group enterprise.  While
major microprocessor  manufacturers such as Intel (NasdaqNM:  INTC) and Advanced
Micro Devices  (NYSE:  AMD) were early  portfolio  licensees,  Alliacense is now
focusing its licensing efforts on system manufacturers.
