Patriot Scientific Announces Licensing Agreement with the LEGO Group

Patent Portfolio Isn't Just for Computers

CARLSBAD, Calif. – August 29, 2007 – Patriot Scientific announced today that the LEGO Group has purchased a license to the Moore Microprocessor Patent (MMP) portfolio. Marking its 75th year in business this month, LEGO has emerged as the world's sixth largest manufacturer of toys, including the MindStorms programmable robots.

"We're delighted with the idea that our technology has enabled LEGO to develop such wonderful educational toys," said Patriot Scientific CEO Jim Turley. "It highlights just how far computer technology has come, that it now appears in everything from playthings to personal computers. Our patented technology is truly ubiquitous. Coincidentally, our company's headquarters is across the street from LEGOLAND California, so LEGO is near to us in the literal sense as well."

LEGO becomes the 21st licensee of the company's fundamental patent portfolio and the fourth in Europe, after Nokia (Finland), Bull (France), and Schneider Electric (Germany). Previously announced licensees include such global corporations as Intel, AMD, Hewlett Packard, Casio, Fujitsu, Sony, Nikon, Seiko Epson, Pentax, Olympus, Kenwood, Agilent, Lexmark, NEC Corporation, Funai Electric, SanDisk and the Sharp Corporation.
