Author Could someone clarify this...

Hi,
I was just reading an interview[0] of someone from the 'Freetype' project
and he said:
....
Also, I still don't understand why Debian and Ubuntu keep distributing
patent-infringing code in FreeType, while they keep MP3 and DVD playback
out of their normal installs. I'm not even sure it's DFSG compliant...
....
Cheers,
K

Almost any interesting program, free software or otherwise, infringes
some unknown, non-zero number of registered software idea patents. If
that were the only criterion for a software work to fail the DFSG,
Debian would be pretty much empty.

My understanding is that Debian declares a work non-free if a holder
of a software idea patent is *actively enforcing* a patent that covers
the work, such that Debian cannot distrigute the work as free
software.

Fraunhofer has a track record of actively enforcing software idea
patents against the algorithms in MP3 encoding software. Thus, such
works cannot be redistributed as DFSG-free software by Debian.

Ditto the DVD-CCA actively enforcing against DeCSS.

I don't know whether that is true for any of the software idea patents
that cover FreeType.

Is there a known case where a holder actively enforces a patent that covers MPEG-4 video encoding?
I am asking, because x264 has been removed out of the Debian archive and there are video codecs disabled in Debian's FFMPEG...

Cheers,
Fabian

Search for "MPEG LA patent litigation", for starters.
