Forgent Settles JPEG Patent Cases 167
eldavojohn writes "As many of you know, the JPEG image compression is actually proprietary. This has resulted in many lawsuits between its owner, Forgent Networks, and other companies that have used it. Yesterday Microsoft and about 60 other defendants settled with Forgent to the tune of $8 million. For a company with annual revenues of $15 million, that's nothing to sneeze at. You haven't heard the last of Forgent yet, as the article states, 'It is currently pursuing claims against cable companies over a patent that it says covers technology inside digital video recorders.' Sounds like that one could be worth a little bit of cash, wouldn't you think?"

Nontrivial yes, but it's arguable if the novelty rises to the level of something patentable.

JPEG compression is trivial. Split the file into 8x8 blocks, line the pixels up diagonally and take the DCT. Divide each value of the DCT by a value from the quantization matrix (which forces high frequency information into small ranges), and then compress with a huffman tree. It's definitely more trivial than, say, vorbis or theora. It's not even the state of the art in image compression a

What happened here is that Forgent sat on a patent while the JPEG format was drafted with the purpose of being open and patent-free. Compression Labs (which Forgent now owns) was a part of the JPEG committee and thus was required to disclose any patents that might deal with the format that the committee was developing. Compression Labs was silent on the matter and Forgent only decided to litigate their patent after many years of silence and after JPEG had become a standard. The patent is likely invalidated by priori art and Forgent is probably also barred by laches due to their delay in enforcing the patent.
I'd rather that no one settle with them, but the reality is that settling is probably cheaper than litigating.

JPEG PATENT CLAIM SURRENDERED:
Forgent Networks Ends Assertion of Patent Challenged by PUBPAT
NEW YORK -- November 2, 2006 -- The Public Patent Foundation ("PUBPAT") announced today that Forgent Networks (Nasdaq: FORG) has stopped asserting its patent against the Joint Photographic Experts Group (JPEG) international standard for the electronic sharing of photo-quality images. PUBPAT successfully initiated a challenge to the patent last year and this week Forgent dropped all of its pending cases asserting the patent and stated that it would not file any other infringement claims based on the patent.
Forgent Networks acquired 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."
More information about the Forgent Networks patent formerly asserted against the JPEG standard, including a copy of the Patent Office's Office Action rejecting its broadest claims, can be found at http://www.pubpat.org/forgentjpeg.htm [pubpat.org].
