Incorrect.  CBR is not patented and Vorbis has no CBR option because
it is not natively CBR.  MP3 is based on fixed sized frames, Vorbis
is not. (MP3 actually implements a limited ABR on top of the fixed
size frame option, so CBR is a misnomer for MP3 as well).

By 'CBR' I mean 'simulated fixed bitrate within a small window of frames', the
same thing it means in MP3 (where the window is nine frames).
