In re Bilski, as the case is known, is "a very big deal", says Dennis D. Crouch of the University of Missouri School of Law. It "has the potential to eliminate an entire class of patents".

Fifty years ago nature study was not part of the school work; scientific forestry was a

Most people hate rock music.
