as you point out, the claims are the important part, with the most legal
significance. you might see a patent with a description of a perpetual
motion machine, but read on to find that the only claim is a workable
device to measure its net power output, if any.

sounds like anti-gravity to me :-) dean kamen might claim the same for the
segway. the patent office allows people lots of latitude in naming their
inventions and choosing words to describe their functions ("an antigravity
device, comprising a vibration generator that climbs a tape..."), as long
as people precisely and clearly describe what the invention does.
