Jpeg patent ‘rejected’ ?

After a few months long reexamination process, the US Patent and Trademark Office rejected few claims of patent for the Joint Photographic Experts Group (Jpeg).

The USPTO granted this patent on 1997. Reexamination process has been started by  the Public Patent Foundation (PubPat), in late 2005. The non profit organization managed to provide valid cases of ‘prior arts’ to the Office.

Forgent (actual ‘patent holder’) states that this is not a complete defeat, because they still hold the majority of claims on the patent, and they will keep defending those ones and trying to overturn Office decision.
