I hate patents as much as the next guy, but to imply a patent is less valid because it was purchased is bunk. Part of the value of patents is that the inventor can sell them. If they aren't as compelling after being sold, then the inventor can not demand as high a price. That doesn't seem fair to the inventor. The fact that the patent has changed hands should not influence anyone's opinion on the matter.
