That's an interesting point that I never thought about.  I suppose they
COULD go after an open source implementation, but what would they have to
gain?  On the other hand, a TV manufacturer puts it in their set and the
patent holders can sue for millions.

I'm still not totally convinced that h265 will take over h264, but who
knows.  And even looking up h.264 licensing, it sounds like you still might
have to pay some usage fees to somebody if you're a big business and not an
end user.
