Last Friday, the Federal Circuit affirmed a district court decision that found for the CBS Corporation in its defense against infringement and invalidity as to three claims of U.S. Patent No. 8,112,504 owned by Personal Audio, LLC. While the jury initially found for Personal Audio, the Patent Trial and Appeal Board (PTAB) later invalidated the ‘504 patent and the district court ultimately entered final judgment for CBS. The ‘504 patent describes a system for organizing audio files, “by subject matter, into ‘program segments.’ The patent utilizes a “session schedule,” which allows a user to navigate through the schedule by skipping the remainder of a segment, restarting a segment, listening to bookmarked “highlight passages,” or switching over to a “cross-referenced position” in another segment.
