I don't know if the JPEG patent under discussion here also covers
JPEG-2000.  From what I saw in the JasPer discussion (in which the
license progressed from extremely non-free to clearly DFSG-free and
BSD-like), there are already several patents over the JPEG-2000 format,
but the patent holders have stated that any "conformant implementation"
(that implements the standard exactly) is always allowed.  The patent
holders also stated that they might choose to go after those who don't
implement the standard, but so far they have not actually done so.  For
that reason, I would put JPEG-2000 in the category of all the other
software in Debian that is probably covered by many different patents
(progress bar, etc): leave it unless someone actually starts enforcing
the patent, and decide what to do then, and in the meantime don't go
looking for patents that affect the software.
