An anonymous reader quotes a report from Techdirt: A lawsuit brought by the world's largest patent troll, Intellectual Ventures, and handled on appeal (as are all patent cases), by the notoriously awful Court of Appeals for the Federal Circuit (CAFC) may have actually killed off software patents. The ruling came from a judge that has ruled over patent cases since the 1980s, and it appears he's been born again into the anti-software patent world. Judge Mayer pointed out that the First Amendment says that "some" patents should not be allowed. The whole concurrence is worth reading, starting with the First Amendment argument -- which is kind of fascinating in that it goes well beyond what most people had talked about in the past concerning software patents. Judge Mayer makes the point that basically all software is unpatentable because software is "a form of language," which we don't patent: "All software implemented on a standard computer should be deemed categorically outside the bounds of Section 101. ("Section 101" is 35 U.S. Code; 101 is the part that governs patents.) The central problem with affording patent protection to generically-implemented software is that standard computers have long been ceded to the public domain .... Because generic computers are ubiquitous and indispensable, in effect the 'basic tool ' of modern life, they are not subject to the patent monopoly. In the section 101 calculus, adding software (which is as abstract as language) to a conventional computer (which rightfully resides in the public domain) results in a patent eligibility score of zero .... Software lies in the antechamber of patentable invention. Because generically-implemented software is an 'idea' insufficiently linked to any defining physical structure other than a standard computer, it is a precursor to technology rather than technology itself."
