TPL Clarifies Stipulation to Dismiss Six Toshiba ASIC Devices From Moore Microprocessor Patent‚Ñ¢ Infringement Suit to Sharpen Focus on Expansive Category of Infringing System Products

CUPERTINO, Calif. - June 28, 2007 - In light of the sweeping scope of infringement of the Moore Microprocessor Patent‚Ñ¢ (MMP) Portfolio by Toshiba system products, The TPL Group and Toshiba stipulated to sharpen the focus of the Texas infringement trial by eliminating certain Toshiba ASIC devices, which were thought to add little to the ultimate infringement findings other than complexity and possible confusion.

According to Dan Leckrone, Chairman of The TPL Group, "The April 17th stipulation to dismiss the Toshiba ASICs was purely procedural and should not be construed as having any substantive significance. This was simply an effort to streamline the infringement trial scheduled for November by sharpening the focus on the expansive category of infringing system products manufactured and sold by Toshiba and the other defendants."

The TPL Group has a 20-year history of investing its resources to commercialize home-grown Intellectual Property (IP) assets in the form of both proprietary technology and proprietary products based on that technology. "Unlike so-called patent trolls, TPL develops IP assets that are used to develop products that are taken to market together with valuable technology that is licensed to global system manufacturers to generate revenue that funds TPL's next round of innovation," added Leckrone. He cited IntellaSys, a TPL Group enterprise that has developed and is currently marketing distributed digital media semiconductor solutions via three major product brands: SEAforth™ multicore processors, Indigita® content secure connectivity devices and OnSpec™ secure storage controllers.

Texas Court Markman Ruling

Commenting on the recent Markman ruling (www.tplgroup.net/ruling) filed by the US District Court in the Eastern District of Texas, Leckrone stated, "This ruling reflects well the skill of the Texas Court in dissecting and dealing with a very complex case over the past 15 months." He noted that while the ruling overwhelmingly confirms MMP Portfolio claims against Matsushita, Panasonic, JVC, Toshiba, and NEC entities, there remains a specific, highly-technical phrase that will require further scrutiny. The court's decision clearly demonstrates why 19 prestigious global companies have already purchased MMP Licenses.

The extensive scope of products that use MMP technology continues to encourage system manufacturers from around the globe to become MMP Licensees. Since January 2006, HP, Casio, Fujitsu, Sony, Nikon, Seiko Epson, Pentax, Olympus, Kenwood, Agilent, Lexmark, Schneider Electric, NEC Corporation, Funai Electric, SanDisk Sharp Corporation and Nokia have all purchased MMP Portfolio Licenses. The two earliest MMP Licensees were marquee chip makers Intel and AMD. By design, the MMP Licensing Program rewards early movers in specific industry segments by subjecting dilatory, slow-moving licensees in those same segments to progressively higher royalty rates.

About the MMP Portfolio

The Moore Microprocessor Patent Portfolio contains intellectual property that is jointly owned by the privately-held TPL Group and publicly-held Patriot Scientific Corporation (OTCBB:PTSC). The portfolio includes seven U.S. patents as well as their European and Japanese counterparts. It is becoming widely recognized that the jointly -owned patents protect fundamental technology used in designing microprocessors, microcontrollers, digital signal processors (DSPs), embedded processors and system-on-chip (SoC) devices. The MMP Portfolio is exclusively managed by Alliacense, a TPL Group Enterprise.

About The TPL Group

Founded in 1988, Technology Properties Limited (The TPL Group) has emerged as a global coalition of high technology enterprises involved in the development, management and commercialization of Intellectual Property (IP) assets as well as the design, manufacture and sales of proprietary products based on these same IP assets. Among the advanced products that The TPL Group enterprises continue to bring to market are system-on-chip solutions for distributed digital media processing applications.

IntellaSys is the division of TPL that managed the SEAForth project. The S40 chip was the ultimate product of that effort. I was chief designer and contributed 55% of the $40M, or so, that it cost.

TPL laid off SEAForth employees in January 2009 and thus terminated the project. The status and future of S40 chips is unclear.
