Again, this does not cover the PMF files. The original files have been
commited by Hewlett-Packard under the MIT/X Consortium license many many
years ago (and the files for the Postscript DDX were later refreshed by
me to fix a minor bug - and I committed them under the same license:
MIT/X.org). The so-called "copyright" notice in these files is just an
attribute which informs the application that the attribute "COPYRIGHT"
has a value. But this value does not relicense the file itself away from
the MIT/X.org license. That would be the same as "relicesing" this email
just because it references the string. References or index data of this
kind cannot be copyrighted, neither in the US nor in Japan nor elsewhere
in the world.

Sure. It may be possible that Adobe Japan did some tricky stuff with CID
fonts, but again this doesn't apply to something which has been
explicitly commited under the MIT/X.org license by the authors.
