Gennum prevails after long dispute over infringement claims concerning two patents related to video synchronization separators

Client(s) Gennum Corporation

Jones Day successfully represented Gennum Corporation in a patent infringement action relating to processing video signals for improved television reception. Pretrial motions reduced monetary exposure from over $70 million to under half of a million dollars. The patentee then withdrew damages from trial, after which the District Court ruled no right to a jury trial. The District Court entered judgment in favor of Gennum on all issues except for the declaratory claims of unenforceability of one of the patents-in-suit and invalidity of a claim of the other patent-in-suit. The Federal Circuit affirmed the lower court's decision on appeal. Jones Day thereafter successfully opposed certiorari after Technology Licensing Corporation (TLC) sought Supreme Court review of the Federal Circuit's decision denying mandamus request for trial by jury.
