PubPat files re-exam request on Forgent's US 4,698,672

PubPat has filed a request for reexamination at the USPTO on Forgent's US 4,698,672, which patent has been asserted against entities that implement the Joint Photographic Experts Group ("JPEG") format

Dan Ravicher: "Forgent Networks is a classic example of the new and rapidly growing trend of patent holders that do nothing more than sue people who make products or services available to the public. Unfortunately, the patent system allows for such perverse behavior because it cares more about patent holders than it does the public."

The request cites US 4,541,012, a patent owned by Compression Labs during the prosecution of the '672 patent.
