13 Companies Cited for Infringement of MMP Portfolio™ in ITC Complaint

The MMP Portfolio™ Licensing Program is Dramatically Strengthened Via Markman Victory and Filing of ITC and District Court Complaints

CARLSBAD, California – July 24, 2012 – (PR Newswire)-Patriot Scientific Corporation (OTCBB: PTSC - News) announced today that the MMP Portfolio Licensing Program – already among the most successful of all-time – is being further enhanced with a first wave of aggressive ITC enforcement activities. Technology Properties Limited (TPL) and Patriot Scientific Corporation (PTSC), have filed a complaint with the US International Trade Commission (ITC) and corresponding complaints in the US District Court for the Northern District of California against 13 companies believed to be infringing the MMP Portfolio patents. The move defends the investments of the enormous MMP Portfolio licensee community of nearly 100 global industry leaders (with combined annual revenue of approximately $1.4 trillion), the investments of PTSC and TPL in the MMP Portfolio Licensing Program, and the investments of TPL in its own semiconductor product lines.

The 13 ITC respondents are: Acer Inc., Amazon.com Inc., Barnes & Noble Inc., Garmin Ltd., HTC Corporation, Huawei Technologies Co. Ltd., Kyocera Corporation, LG Electronics, Nintendo Co. Ltd., Novatel Wireless Inc., Samsung Electronics Co. Ltd., Sierra Wireless Inc., and ZTE Corporation.

The three-pronged strategy includes: (1) a Complaint filed with the US International Trade Commission seeking an Exclusion Order prohibiting the importation of unlicensed products; (2) parallel actions in US District Court seeking damages for past infringement that includes past un-paid royalties -- plus the interest which has accrued on those royalties -- both tripled for willful infringement, plus attorney’s fees; and, (3) the pursuit of injunctions in both the US District Court and the ITC barring the sale of infringing products in the United States in the future.

These latest lawsuits come close on the heels of Alliacense’s unprecedented series of 17 consecutive re- examination victories spanning six years of spurious attacks from a powerful group of serial infringers.

And on June 12, 2012, the US District Court for the Northern District of California issued a “Markman” ruling, remarkable for its resounding defeat of the last-remaining ground being clung to by a recalcitrant group of unlicensed, serial infringers. In so doing, the Court aligns with the MMP Portfolio’s 2006 Markman victory, handed down by Judge Ward in the US District Court for the Eastern District of Texas, and decisively confirms the claim construction arguments of the Alliacense Team.
