Message-ID: <479@ellie.UUCP> Date: Sun, 21-Jul-85 14:31:07 EDT Article-I.D.: ellie.479 Posted: Sun Jul 21 14:31:07 1985 Date-Received: Wed, 24-Jul-85 05:42:03 EDT References: <9028@ucbvax.ARPA> <490@calmasd.UUCP> Organization: SUNY/Buffalo Computer Science Lines: 22 I just read an article complaining that it seemed ironic that after fighting NSA to keep the RSA algorithm unclassified, RSA were trying to prevent its use through the patent system. This comment reflects an unfortunate misconception about the patent system. The purpose of the patent system is to PROMOTE, not inhibit, the widespread use of inventions. A principal requirement of the patent system is that a complete description of the invention be published in a publically available form (the patent gazette). In order to encourage inventors to patent their inventions, they are allowed up to 34 years (soon to be longer for medical inventions) of royalties. The alternative to the patent system is the widespread use of trade secrets, which would permanently prevent anyone from using a protected invention at any cost. If neither form of protection were available, industrial innovation would grind to a fairly rapid halt. The patent system might allow an inventor to charge prohibitively high fees for a license; however, I believe that such fees have previously been successfully challenged in anti-trust suits; any lawyers that know specifics please inform us. Note that in any case the invention is in the public domain after 34 years.
