Jesus is right on the issue. Is the dissemination of a program a
patent infringement. Currently, it is unclear, though I do suspect
that, at least in the state, you would be prosecuted for distributing
a program with a patented algorithm, for eample RSA or LZW.
And the current attempt in Europe is to patents "programs as such", i.e.
information on a physical medium (floppy, CD, paper ???).
But as Jesus is saying, that is only the description of a process:
- identical to a mathematical description
(programs are mathematical proofs)
- identical to a precise enough patent (as required by law)
So writing books or disseminating the patent becomes an infringement.
Absurd ... sure. Where is the line.
The point is:
1- a program is information, and information should not be
patentable.
2- information should not even be contributory infringement, since
the purpose of patents is to disseminate information.
Hence patenting should only concern programs embedded in a physical
device or process that makes use of them. As has always been the case
with math formaulae.
