PENTAX Joins Growing Roster of Global Manufacturers Licensed to Use the Moore Microprocessor Patent™ Portfolio; PENTAX Becomes Seventh Major System Manufacturer During 2006 to Purchase Rights to Use Fundamental MMP Portfolio Technologies

Business Wire, June 28, 2006

CUPERTINO, Calif. -- Alliacense today announced that PENTAX Corporation has agreed to purchase, pending approval by its Board, a license to use the Moore Microprocessor Patent(TM) (MMP) Portfolio. Six other major system manufacturers have purchased MMP licenses from The TPL Group this year. Prior licensees include HP, Casio, Fujitsu, Sony and Nikon as well as Seiko Epson, whose Board approved this week its earlier-announced agreement to purchase an MMP license.

"Our roster of MMP Portfolio licensees is beginning to look like the 'Who's Who' in the world of Intellectual Property," said Mac Leckrone, Alliacense president. "PENTAX along with prior licensees are each in their own right leading developers of intellectual property; and it is therefore gratifying to have them quickly recognize the import of the fundamental technologies protected by the MMP Portfolio."

With PENTAX becoming the seventh system manufacturer to purchase an MMP license in as many months, Leckrone added, "As the First Round MMP Portfolio licensing berths in many industry sectors are being captured, royalty rates are increasing according to plan. At this stage of our licensing program, we are continuing to focus on industry leaders whose management is empowered to make quick strategic business decisions."

The MMP Portfolio patents, filed by The TPL Group in the 1980s, cover techniques that enable higher performance and lower cost designs, and are fundamental to consumer and commercial digital systems ranging from DVD players, cell phones and portable music players, to communications infrastructure, medical equipment, and automobiles.
