Forgent JPEG Related Patent
PUBPAT filed a formal request with the United States Patent and Trademark Office in November 2005 to revoke the patent Forgent Networks Inc. (Nasdaq: FORG) is widely asserting against the Joint Photographic Experts Group (JPEG) international standard for the electronic sharing of photo-quality images. In its filing, PUBPAT submitted previously unseen prior art showing that the patent, which was issued in 1987 to Forgent's subsidiary Compression Labs Inc., was not new and, as such, should be revoked. The PTO granted PUBPAT's request in February 2006 and rejected the broadest claims of the patent in May 2006. In November 2006, Forgent abandoned all assertion of the patent.
