Exhibit 99.1

UNWIRED PLANET TERMINATES ITC LITIGATION; INTENDS TO PURSUE MATTER IN DISTRICT COURT OF DELAWARE

RENO, NV – October 15, 2012 – Unwired Planet, (Nasdaq: UPIP), today commented on its pending investigation against Apple and Research-in-Motion at the International Trade Commission (ITC). For more information, please see Unwired Planet’s blog at www.unwiredplanet.com/unwired-planet-blog/

On Thursday, October 11, 2012, Administrative Law Judge (“ALJ”) Gildea declined to stay the pending investigation despite a joint motion filed by all of the parties. The denial of the joint motion further postponed the ability to appeal what Unwired Planet considers an erroneous claim construction. Rather than proceed with the trial, Unwired Planet has determined that it is in the shareholders’ best interest for the Company to terminate the investigation.

Instead, the Company intends to continue to pursue the matter in its pending case in the Federal District Court of Delaware, which was initially filed in August 2011 in parallel with — and involving the same patents as — the ITC investigation, and provides the Company with an opportunity to seek a corrected claim construction in the federal court.

The Company has established a blog to provide more details on this and other matters at www.unwiredplanet.com/unwired-planet-blog/. Please visit that site for an expanded summary of events, the Company’s perspective and procedural status.
