Hi, I've just read this on Vorbis Xtreme site: "11. YOU SAY THAT OGG VORBIS IS PATENT-FREE, BUT I SAW A PATENT NAMED 'JOINT-STEREO' ON FRAUNHOFER'S PATENT LIST? SO OGG VORBIS ACTUALLY ISN'T PATENT-FREE SINCE IT ALSO USES JOINT-STEREO? No. You can't judge on a patent just by looking at its name - what's 'inside' is what matters. So if the name of the patent says 'joint-stereo', that doesn't mean that all kind of joint-stereo coding is patented (besides, this isn't possible because joint-stereo as a concept is prior-art - it was used long before MP3 came to life)." By reading that, readers can assume that Vorbis does use joint-stereo. Does it?

Implementation work is currently under way, and as with everything in vorbis, it will be a method unencumbered by patent.
