You are right, my working with MP3 technology was in 1999 so my
"standards" are very old :-)
Anyway Fraunhofer Institute which holds most known patents about MPEG
Layer III does not say "Patents expired" so maybe they can have a later
patent over technology trying to enforce it in a future and keep control
of the royalties.
Releasing a mp3 codec now could be safe in Europe (and 2018 in EEUU) but
a hardware piece could be a problem if a later patent appears in the
game. In the other hand as all known patents has expired I think no
court will be against you, maybe a "cease and desists" at most.
Anyway mp3 technology is surpassed a lot by others.
