Onkyo Purchases Moore Microprocessor Patent Portfolio License

CUPERTINO, Calif.-- April 28, 2008 --Alliacense today announced that Onkyo Corporation has purchased a Moore Microprocessor Patent™ (MMP) Portfolio license from The TPL Group. Onkyo manufactures and sells a range of audio, video and home theater products.

“Onkyo is our eleventh MMP Portfolio licensee this year, and the second of the past week,” said Roy Maharaj, Vice President, Licensing for Alliacense. “As the number of our MMP licensees continues to grow, so has the business appeal of our licensing program. Obviously we are delighted by the momentum.”

The sweeping scope of applications using MMP Portfolio design techniques continues to encourage the world’s leading manufacturers of end user products from around the globe to become MMP Portfolio licensees. Over 40 global companies from the US, Europe, Japan, Korea and Taiwan have purchased MMP Portfolio licenses, including many industry leaders such as Fujitsu, Hewlett Packard, Kenwood, Mattel, Nokia, Philips, and Sony.

The MMP Portfolio patents, filed by The TPL Group in the 1980s, cover techniques that enable higher performance and lower cost designs. These patents are fundamental to dozens of microprocessor-based key features and benefits in contemporary consumer and commercial products ranging from DVD players, mobile phones and portable music players to automobile systems, communications infrastructure and medical equipment.
