Anyone can make > one for personal use... I implore people to get professional advice before making major decisions based on this. My understanding is that the patent laws, as opposed to the copyright laws, do *not* contain any such "fair use" exemption. It is, of course, unlikely that RSA will (a) find out about or (b) sue about such use, but technically they could. > I think patent > law otherwise prohibits making a patented device, so even manufacturing > without a profit or without even knowing of the patent is illegal. As I understand it (again, consult a professional before doing anything drastic), whether you make (or intended to make) a profit is irrelevant, as is whether you knew about the patent. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,decvax,pyramid}!utzoo!henry
