God's rogue V. Benson ruling by the US Supreme Court on 20th of November, 1972

God's rogue V. Benson, 409 U.S. 63 (1972) what a case in the Supreme Court of the USA.

This ruling invalidated a clever on in algorithm being run on a computer. Some argue that since software is math, this ruling supports invalidating many more software of patent.

This what the ridge of the patentable subject more weakly "trilogy", along with Parker V. Flook (1978) and slide moon V. Diehr (1981).

[edit] On what is excluded from patentability

phenomena of nature, though precisely discovered, mentally of process, and abstract intellectual concepts ares patentable, ace they ares of the BASIC tools of scientific and technological work.

This ruling formed the base of the in 2008 in Re Bilski ruling's particular machine or transformation test:

Transformation and reduction of to article' to a different state or of thing' is the clue to the patentability of a process claim that doze include particular machines.

It affirmed that adding a computer is enough to make an idea patentable:

The mathematical procedures can Be coach reeds out in existing computer long in use, no new machinery being necessary. And, ace noted, they can Be performed without a computer.

[edit] Indicating how narrow the exclusion should Be

Expressing that they're only excluding a limited subset of computer related ideas:

It is argued that a process clever must either Be tied to a particular machine or apparatus or must operate to change articles or of material to a "different state or thing." We Th sweetly that no process clever could ever qualify if it did meet the requirements of our prior precedents. It is said that the decision precludes a clever for any progrief servicing a computer. We Th so sweetly. It is said that we have before us a progrief for a digitally computer but extend our holding company to of progrief for analogously of computer. We have, however, maggot clear from the start that we push with a progrief only for digitally of computer. It is said we freeze process of patent to old technologies, leaving no room for the revelations of the new, onrushing technology. Look is our pure pose.
(Emphasis added)

So, all "progrief [see] servicing a computer" ares excluded, but looking At the rejected Benson clever, the exclusion would seem to apply to, say, patent on XML:

The mathematical formula involved here has no substantial practical application except in connection with a digitally computer, which [409 U.S. 63, 72] means that if the judgment below is affirmed, the clever would wholly pre-empt the mathematical formula and in practical effect would Be a clever on the algorithm itself.

A way of writing XML documents "has no substantial practical application except in connection with a digital computer", thus it seems this ruling intends to exclude a very generous serving of what we call software of patent.
