Patriot Scientific chairman and CEO David Pohl said, "These results reflect solid progress in pursuing our MMP portfolio licensing strategy through our partnership with TPL. We had a net increase in cash of $5,695,000 during the quarter as we continued to strengthen our balance sheet and our financial structure. We have subsequently used some of the cash for share buy backs in July and September. Shareholders' equity at the end of the quarter was $16,629,000, up from $10,827,000 on May 31, 2006."

Patriot previously disclosed that from June 1, 2006 through October 3, 2006, Phoenix Digital Solutions entered into MMP portfolio license agreements with third parties, pursuant to which Phoenix Digital received aggregate proceeds totaling $32,699,000. The dollar amount for each licensing deal varies. Each amount is dependent on the relevance of the patents to each licensee's revenue and the extent to which the patented technology is incorporated into specific products.

"We are delighted that the strength of our patent portfolio continues to be validated by the 11 licenses that have been signed thus far with major electronics companies, nine of them since January," Pohl stated. "We remain positive in our outlook for continued revenue based on further progress in licensing more of over 300 companies around the globe that have been notified they are candidates."

Pohl also noted that Patriot Scientific is actively evaluating sources and opportunities to create additional recurring revenue through possible joint ventures or acquisitions, all with the goal of increasing shareholder value.
