IANAL, but as I understand it, a patent cannot cover "the entire
concept" of something as general as "audio compression using perceptual
encoding". Instead, you patent a specific method of doing something,
describing in detail exactly how your process works. Something that
accomplishes the same result by a different means isn't covered by the

This, of course, is a political judgment, not a legal statement, and is

IANAAEE (... not an Audio Encoding Expert), but IIRC, Monty was well
aware of wavelets when he created Vorbis, and intentionally chose not to
use them.
