Letter to Shareholders from Patriot Scientific President and CEO Rick Goerner

CARLSBAD, Calif.--(Business Wire)--
Patriot Scientific Corp. (OTCBB:PTSC) today issued the following
letter to all shareholders.

To all shareholders and supporters of Patriot Scientific, this is
my second letter to the shareholders, a communication vehicle that I
hope will become a valuable means to provide insight to you on topical
issues and provide a uniform status report on activities at the
company. Toward that end, I'd like to focus on three issues: Our Q3
earnings report, Patriot's "blueprint" for future activities and
shareholders' feedback and concerns.

Q3 results

I will not, in the limited context of this letter, recount all the
information contained in our April 9, 2008 earnings release, which
fully reflects the financial results of all transactions announced
prior to the end of January 2008. PDS-related licensing activities and
results were generally improved from the year earlier quarter, with a
strong cash position and PTSC's public listing and share value, I am
moving forward on our plan to use these resources to assess new
opportunities for investment that should provide additional growth
prospects for Patriot in the future.

Under the terms of our licensing agreements, all of our MMP(TM)
portfolio license agreements are confidential and the individual terms
of any agreement cannot be publicly disclosed. Each MMP(TM) portfolio
licensing negotiation is unique with respect to the customer's use of
the MMP(TM) portfolio technology, as assessed by TPL (in explicit
technical detail), the costs associated with pursuing the customer
licenses and other considerations.

We continue to license new customers, as evidenced by new licenses
closed in recent months.

Positioning Patriot for future growth

I trust you have seen the announcement that Paul Bibeau has joined
the company in the role of Vice President, Business Development
reporting to me. Paul has extensive electronic industry experience and
joins us from a public company as well. Paul has hit the ground
running in providing additional bandwidth to the company to help
develop a template for assessing new investment and M&A activities for
Patriot. We have begun exploratory dialogues with several technology
companies.

The blueprint for Patriot's pursuit of these opportunities can be
summarized as follows:

-- Selective expansion of our IP portfolio, acquiring new IP that
builds on our existing IP portfolio.

-- Minority investments, undertaken as a strategic investor, in
certain early-revenue or technology ventures that, currently
do not support a full acquisition decision, but that represent
a technology or capability of interest to us. Patriot would
gain market and technology insights from our participation in
a potential "pre-M&A" investment scenario.

-- Aggressively pursue full M&A activities. We will steer the
company toward the acquisition of operating businesses in the
electronics sector focused on software, networking and/or
wireless technologies. Patriot has public market access to
attract certain private or foreign entities. We are not ruling
out the consideration of an acquisition of another public
entity either. Patriot's strong cash position, public company
posture and significant market capitalization value give us a
very solid negotiating position, especially considering
current market conditions and other companies' limited access
to cash.

While it is the last category that will consume the majority of
our energies, Paul, Cliff and I have begun initial assessments of
several different companies and IP portfolios representing
opportunities to expand PTSC's revenues in each of the above. We will
keep you updated of progress as it occurs. When appropriate, Patriot
will enlist the services of an investment banker.

Shareholders' feedback and concerns

During the past month I have collected feedback from shareholders,
received input from our investor relations and public relations groups
and have had direct conversations with several shareholders to better
understand the issues and concerns facing the company through your
eyes. The vast majority of these issues seem to fall into four primary
areas:

1. Shareholder communications and visibility of Patriot's activities
2. Requests for details regarding specific MMP(TM) portfolio licenses
3. The proposed Patent Reform legislation
4. How to increase the shareholder value of PTSC shares

Shareholder communications and visibility of Patriot's activities

It is my intention, starting with these letters, to provide
regular, concise and valuable information to our shareholders. The
extent of the information will be, of course, subject to the
disclosures that can be made by a public company under governing laws
and corporate compliance oversight. I am working closely with our
investor relations firm, Hawk Associates, to better understand their
needs with respect to daily communications that come to them via
letters and emails from shareholders. In the longer term, I will
strive to create a quarterly mechanism to provide more direct access
to management (possibly a quarterly conference call) before the next
shareholders meeting in October of this year.

Requests for details regarding specific MMP(TM) portfolio licenses

Patriot cannot, and will not, disclose the details of individual
license agreements on the MMP(TM) portfolio.

I understand that this remains a clear source of frustration with
our shareholders.

The proposed Patent Reform legislation

We have fielded many questions regarding the pending Patent Reform
Act (PRA) legislation. Patriot Scientific does not feel it is in the
best interest of the industry to pass the proposed Patent Reform Act
(PRA) legislation, and we continue to ask our shareholders to write to
their lawmakers opposing this legislation. We believe that the impact
of this legislation will hinder innovation in smaller companies and
limit their competitiveness. As Patriot moves into the M&A arena,
acquiring operating entities, this concern for IP protection will
become a more prevalent concern. In summary, the currently proposed
bills are on balance not favorable to Patriot. While it is my
understanding that the current bills have not yet been scheduled for
vote, and they could change in content before a final vote, we stand
against their passing into law. I will keep you updated from time to
time on the acts and their implication for our business and answer
more of your questions regarding this legislation in my next letter.

How to increase the shareholder value of PTSC shares

It is my opinion, and the opinion of Patriot's Board of Directors,
that the mechanism to build long term and sustainable shareholder
value for Patriot shareholders is through the deployment of our
current, and future, cash flow into investments as discussed above. It
is our objective to build a company with operating profitability and
revenue growth in expanding markets to drive Patriot's future market
value. The criteria we have outlined for M&A will target
revenue-producing companies at, or near, operating profitability in
niche, growth markets. I expect that we will use a combination of
cash, equity, and less likely debt to accomplish these objectives.

My objective is to close our first M&A transaction before calendar
year-end. As a result, Patriot will continue to hold further dividend
distributions, for the near term, and evaluate their applicability in
future quarters. It is also our plan, at the time of a significant M&A
transaction, to evaluate our ability to transfer our listing to a
broader-followed, national exchange, compliant with their listing
requirements.

I hope this letter has provided you with some additional insight
into our future plans for Patriot Scientific and that I have answered
some of your questions. I look forward to your comments and questions
to help improve the quality of subsequent letters.

I am very excited about the opportunity to build on Patriot's past
successes and hope, that in the coming months, you will come to share
that excitement with me as well.
