Microprocessor design technology is everywhere:

Patriot Scientific was founded in 1987 with technologies applicable for DoD (U.S. Department of Defense) applications. In 1994 Patriot Scientific Corp. (PTSC) developed a unique 32-bit microprocessor architecture that evolved into the IGNITE I™ and IGNITE II™. In 2001, Patriot Scientific began offering the "core" of its microprocessor chip in the form of licensable intellectual property (IP) so that other companies could develop their own Ignite-based products. As microprocessor designs matured, it became clear that Patriot Scientific's patented microprocessor technology was setting the standard for efficient low-cost and low-power computing. The company again evolved from design and manufacturing into a powerful holding company with global licensing opportunities in the $200+ billion microprocessor end-use market.

In 2005, Patriot Scientific unified its patent portfolio with The TPL Group, creating the Moore Microprocessor Patent (MMP) Portfolio™ that collectively strengthening the company’s intellectual property coverage that is elemental to nearly every microprocessor design. This unified portfolio is well positioned for significant global licensing opportunities. Intel, AMD, and Hewlett Packard were among the very first licensees of the MMP portfolio, a group that now includes more than 30 global corporations. The TPL Group is exclusively responsible for the ongoing commercialization and licensing of the unified patent portfolio.

In 2007 Patriot acquired 46% of Holocom Networks, a company making security enclosures for secure networking applications, primarily to military, government agency and defense contractors.

In 2008 Patriot increased its ownership to greater than 37% in Talis Data Systems, LLC, a San Diego company that produces multi-domain computer and network security products to government, military and enterprise customers.

Patriot closed its first software company acquisition on September 1, 2008. The Company acquired Crossflo Systems, Inc., a San Diego, California private software and services company noted for its innovative data-sharing solutions, for stock and cash totaling $10 million. Crossflo is building a base of clients in justice and public safety, homeland security and public healthcare that have a critical need for secure, selective, scalable and nondisruptive data-sharing.

On September 8, 2008 Patriot announced it had acquired nearly 20 percent of Avot Media, a Sunnyvale, CA, private software innovator in near real-time streaming and video delivery to mobile devices with a high-quality image.

On December 1, 2008 Patriot closed its acquisition of all the assets of Verras Medical dba Iameter. The Iameter portfolio of data analysis software and programs will be utilized to expand the current healthcare data sharing and analysis capabilities of the company. Iameter is now a Crossflo product line.

On March 31, 2009 Crossflo through Patriot closed its acquisition of the Vigilys assets from Kratos Defense and Security Solutions. The Vigilys product portfolio further leverages the Crossflo technology in the public safety sector and addresses the need for real-time resource visualization for first responders in justice and public safety arenas, including fusion center emergency operations.

In June 2009 Patriot Scientific announced the creation of Patriot Data Solutions Group (PDSG) replacing the Crossflo Systems name. The new company unites Patriot's acquired entities and software technologies into a portfolio encompassing best-of-breed data sharing technologies and services in healthcare, public safety, and justice.
