A patent is no assurance of anything, least of all the technical 
validity of the idea, except for possibly the opportunity to argue the 
merits of it in front of a judge and/or jury comprised of people even 
more technically ignorant than the folks at the patent office who 
granted it.  For the most part, the only requirement for a patent is 
that the idea be unique, not that it have any relationship to the laws 
of science, and even that criteria fails absurdly often in actual practice.
