PLANO, TEXAS – October 8, 2014 – ContentGuard, a subsidiary of Pendrell Corporation (NASDAQ:PCO) and a pioneer of content protection technologies, today introduced Yovo, a new ephemeral messaging app that does much more than simply make the photos and messages that we share disappear. Yovo is the first app that allows users to protect pictures and messages, both old and new, and from undesired screen captures via a patent-pending scrambling technology. Users can also blur photos and selectively choose who can discover what is behind the blur, and set self-destruct timers for photos and messages from one second to 24 hours. What’s more, Yovo allows users to share time-based and protected content with friends across social media, including Facebook and Twitter. (Read More)

By | Press Release | 236 Comments

PLANO, Texas  (PR Newswire) – July 2, 2014 – ContentGuard Holdings, Inc. (“ContentGuard”), a subsidiary of Pendrell Corporation (NASDAQ: PCO), announced today that the Patent Trial and Appeal Board (PTAB) of the United States Patent and Trademark Office (USPTO) issued final written decisions on June 26, 2014 and July 1, 2014 finding valid all claims of the ContentGuard digital rights management (DRM) patents at issue. These decisions follow patent trials conducted before the PTAB in February 2014.

The inter partes review (IPR) proceedings at the USPTO, through which these trials were conducted, were initiated in February 2013 by one of a handful of handset manufacturers who have not yet licensed ContentGuard’s DRM technologies.  These unlicensed companies have put themselves at an unfair competitive advantage over the many companies who have licensed these technologies.
