Parent article: Public Patent Foundation challenges JPEG patent
It is clear from reading the PDF that the Public Patent Foundation
thinks the claims of patent in question are made obvious by another
patent that was filed a year earlier.
However that other patent is also owned by the same company (CLI).
So it seems that if the JPEG patent is invalidated, then CLI can
use that earlier patent to claim infringement against all creators
of JPEG software.
