Openwave Systems Secures Uncontested Ownership of Certain Patents

REDWOOD CITY, CA - August 29, 2011 --

Openwave Systems Inc. (Nasdaq: OPWV), a global software innovator delivering all-Internet Protocol (all-IP) mediation and messaging solutions, said it will appear this morning in the U.S. District Court in the Northern District of California to seek Court review of an agreement that would dismiss litigation which Openwave filed against Swiss-based Myriad Group AG and Myriad France SAS (“Myriad”).

Under terms of the proposed agreement, Openwave secures from Myriad the uncontested ownership of a portfolio of patents that are at the foundation of the mobile web. In exchange, Openwave agrees to pay $12 million in cash to Myriad.

The litigation grew out of a 2008 purchase by Myriad from Openwave of certain mobile phone products and the patents practiced in those mobile phone products. The agreement ends all of Myriad’s claims to Openwave’s patents and Openwave’s litigation against Myriad.

“The resolution of this litigation clears the way for Openwave to pursue, without encumbrances, one of its programs to monetize certain assets in its intellectual property portfolio,” said Anne Brennan, Chief Financial Officer of Openwave Systems.
