CUPERTINO, Calif.--(BUSINESS WIRE)--Alliacense announced today that the USPTO has affirmed the validity of US’336, the most widely recognized patent in the MMP Portfolio™.

The TPL Group has extended its remarkable string of successes against multiple validity attacks on the MMP Portfolio perpetrated by numerous electronics industry giants from around the world. These victories significantly strengthen the MMP Portfolio patents – and accordingly, magnify the risk for those companies without a license to the technology. Recent key victories include:

• August - September 2009. The USPTO indicates it will issue a Reexamination Certificate for the US’336 “Dual Asynchronous Clock” patent, ending reexaminations filed by NEC, Toshiba, and the Public Patent Foundation; and resoundingly rejects another attempted attack by litigant HTC.
• July 2009. The USPTO issues a Reexam Certificate for the US’584 “Multiple Instruction Fetch” patent over the reexaminations filed by litigants NEC and Toshiba.
• January 2009. The German Patent Court confirms the validity of MMP Portfolio™ patent EP’730 rejecting a “nullity action” brought by Deutsch Telecom.

“This remarkable story demonstrates,” said Mac Leckrone, President of Alliacense, “that the reexam delay tactic routinely encouraged by lawyers defies business sense, since it usually backfires by strengthening the very patents under attack.”

Combined with favorable “Markman” Rulings in the Eastern District of Texas in 2007, and the steady addition of over 60 licensees since the launch of the Licensing Program in 2005, the MMP Portfolio™ continues its phenomenal ascendance as one of the most important patent portfolios in the history of electronics.

Mike Davis, Senior Vice President of Licensing, added, “These developments obviously diminish any uncertainties associated with purchasing the required MMP Portfolio license, and will thus have a direct impact on the market price going forward.” Davis also confirmed that progressively higher royalty rates remain a basic principle of the MMP Portfolio Licensing Program.
