Verigy Purchases Moore Microprocessor Patent Portfolio License

CUPERTINO, Calif.-- December 21, 2007 --Alliacense today announced that Verigy Ltd. has purchased a Moore Microprocessor Patent™ (MMP) Portfolio license from The TPL Group. Verigy is a premier automated test equipment company with two decades of heritage in semiconductor test.

“This agreement is in the best interests of Verigy, its shareholders and customers because it removes the possibility of supply chain disruptions,” said Mike Davis, Senior Vice President, Licensing for Alliacense. “A strong wave of interest from companies selling microprocessor-based products has propelled the MMP Portfolio Licensing Program to the next level, as over 45% of license signings have followed the favorable Markman ruling issued earlier this summer.”

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. Since January 2006 over 30 global companies from the US, Europe, Japan, Korea and Taiwan have purchased MMP Portfolio licenses.

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 which today have dozens of microprocessor-based key features and benefits.
