JPEG PATENT CLAIM SURRENDERED: Forgent Networks Ends Assertion of Patent Challenged by PUBPAT
Forgent Networks acquired U.S. Patent No. 4,698,672 (the '672 Patent) through the purchase of Compression Labs, Inc. in 1997 and began aggressively asserting it against the JPEG standard through lawsuits and the media in 2004. PUBPAT filed its challenge to the patent in November 2005 and the Patent Office rejected the patent's broadest claims in May of this year.
"By completely ending its assertion of the '672 patent, Forgent has now finally admitted that the patent has no valid claim over the JPEG standard," said Dan Ravicher, PUBPAT's Executive Director. "This utter capitulation by Forgent is long overdue, but a cause for public relief nonetheless."
