Unified Successfully Holds Unpatentable All Challenged Claims of Dragon IP Patent

On February 5, 2015, the Patent Trial and Appeal Board, in an inter partes review brought by Unified Patents, held all challenged claims unpatentable.

IPR2015-01254 was brought by Unified to protect, inter alia, content delivery technologies. The challenged patent, U.S. Patent 5,930,444, claimed to have invented audiovisual recording and playback devices (e.g., TiVo-style recorders) that provide substantially simultaneous recording and playback, allowing user-controlled programming delay. The Board found that challenged claims 1, 2, 7, 8, 10, 13, and 14 were unpatentable over the prior art combinations of record, which included a successful inherency argument.

The '444 patent has been asserted in at least 10 district court cases in the District of Delaware. There are Rule 11 motions for sanctions pending there.

A copy of the ruling is included below.
