PUBPAT Makes Progress Against JPEG Patent
The Data Compression News Blog writes "The US Patent Office has granted the Public Patent Foundation's request for a reexamination of the patent
which Forgent Networks is reportedly using to harass anyone that implements the
widely used JPEG format. They have already been challenged by many, but PUBPAT
had the first concrete case with 'prior art'.
In its Order granting PUBPAT's request, the Patent Office found that PUBPAT
raised 'a substantial new question of patentability' regarding every claim of
the the '672 Patent."
Question: If a corporation like this recieves licence fees for an invalid patent, What is preventing the licensees suing them for the money that they have extorted?

I'd just like everyone to know, I've filed a claim of prior art in the name of a long deceased relative on ASCII, and every poster here may be in violation of my patent. Please remove your posts at once or I will be disposed to take legal action. Your IP has been logged.
Neither of the commenters to date take your question seriously, so I'll make a guess: at the time software was developed to encode and decode JPEG, it was not common knowledge that JPEGs were ostensibly patent-encumbered. As far as I know, no unencumbered alternative to JPEG was developed. But it is widely understood among those who deal with these matters that MP3 is patent-encumbered and that we should use and encourage others to use the apparently unencumbered (and higher quality, besides) Ogg Vorbis instead.
