-----BEGIN PGP SIGNED MESSAGE----- The exemption is a part of the sections of the US code pertaining to patents. As I understand it, the exemption allows you to build _one_ instance of a patented item for your _own_ _personal_ research. If you as an individual want to keep a patented bunny as a pet, you're probably OK. If you want to use PGP, as an ividual, you're probably OK. If you want to use those patented items for anything else, you're probably not OK, thus the recent interest in a commercial-and-infringement-proof PGP. Witness the just-decided Litton-Honeywell patent infringement case. Litton obtained a $1.2G judgement against Honeywell, which used a method patented by Litton to manufacture its very successful ring laser gyros. Since damages in patent infringement cases are based on actual damages (with a 3x increase possible if the jury decides that the infringement was deliberate), the Litton-Honeywell case might give a manufacturer pause. I bet that PKP would be unable to show that my use of PGP has caused them _any_ actual (or even potential) damages. However, Apple (or Lotus, or any of the other RSA licensees) have obviously decided that they'd rather play {safe,fair} and license the patents directly. - -Paul - -- Paul Robichaux, KD4JZG | "Change the world for a better tomorrow.
