Patriot Scientific was founded in 1987 with technologies applicable for U.S. Department of Defence applications. In 1994, the company developed a 32-bit microprocessor architecture and in 2001 it began licensing its microprocessor chip as an IP core.

Patriot Scientific evolved in 2005 into a IPR holding company, unifying its patent portfolio with the TPL group, which focuses on IPR management services, including the maximization of cash return of IPR portfolios. The Patriot Scientific patents are commercialized by Alliacence, a TPL Group enterprise,which according to its own description employs a cadre of IP-licensing strategists. TPL and Patriot assert that their jointly owned patents protect techniques used in almost all microprocessors,microcontrollers, digital signal processors, embedded processors, and SoC implementations. Patriot and TPL believe that at least three of their patents are elemental to virtually every microprocessordesign. These include:

• U.S. 5,809,336: Clocking CPU and I/O Separately

• U.S. 6,598,148: Use of Multiple Cores and Embedded Memory

• U.S. 5,784,584: Multiple Instruction Fetch.

The patents were granted in 1998 and they are valid through 2015. The Patriot patent portfolio is licensed by Intel, AMD, HP, Casio, Fujitsu, Sony, Nikon, Olympus, Kenwood, and Nokia, among others.
