Any patented parts cannot be part of gnupdf, unless of course the
patent owner writes a letter promising to allow the feature to be used
and distributed under the GPL3 etc. for now and in the future,
including the continued protection of that status even if he sold or
transferred the patent through any other means.  Otherwise we have to
wait until the patent lapses.  This, for example, was the problem with
the LZW compression used in earlier PDF specifications; the patents on
LZW have now lapsed so it can now be included.

 It is a peculiar situation since there are conflicting interests
which prevent the entire specification from being implemented for at
least a few more years.
