PTSC Streamlines Subsidiary Operations

Reduces Operating Expenses While Reaffirming Core Focus

CARLSBAD, Calif., Nov. 12 /PRNewswire-FirstCall/ -- Patriot Scientific
Corporation (OTC Bulletin Board: PTSC) announced it has taken measures to
reduce expenses at its wholly owned subsidiary Patriot Data Solutions Group,
Inc. ("PDSG"), while reaffirming its commitment to provide state of the art
data-sharing solutions which include the Company's flagship technology, the
Crossflo DataExchange® platform ("CDX").

"We have taken measures to restructure PDSG and to rationalize our level of
investment in an aggressive move to better position ourselves to service near
term opportunities," said Cliff Flowers, PTSC's Interim CEO. "While we are
refocusing our efforts to exploit opportunities for the CDX and Vigilys
platforms, we are also undertaking to divest ourselves of the Iameter
portfolio of data analysis software and programs. The planned Iameter
divestiture, in conjunction with already implemented reductions in staffing,
contractor engagements, and other expenditures, will reduce PDSG's cash burn
by approximately 40 percent," added Mr. Flowers. PTSC based its decision, in
part, on preliminary recommendations from its consulting partner, Eclat, and
the need to preserve cash resources. Additional considerations were given to
PTSC's expected improved traction in the justice and public safety markets,
and the excellent results of the recent CDX technology evaluation which
included the reassessment of CDX as a core driver for maximizing shareholder
value.

The Company also announced that its next shareholder meeting will be held on
January 28, 2010 at 2 p.m. (Central Standard Time) at the InterContinental
Chicago, 505 North Michigan Avenue, Chicago, Illinois 60611. The move to the
Chicago location was undertaken to better accommodate shareholder access from
various locations across the country. Further details pertaining to the
shareholder meeting will become available in PTSC's proxy statement expected
to be filed with the Securities and Exchange Commission on or about December
7, 2009.
