I've heard the claim that it's patent-free hundreds of times. The
FAQ at vorbis.com says:

But last time I checked breathing was patented, so I've always been
dubious of the claims. I don't know that it's possible to do an
exhaustive patent search to make this claim with a very high
confidence level.
So far nobody's sued, though, which is a good sign compared with
other formats.
Also, remember, Ogg is the container, vorbis is the codec. You can
have a FLAC Ogg, for instance.
