"Groklaw's take: Bilski: "It's Affirmed, But …No Decision on Software Patentability. The lower court's decision is affirmed, and so no patent for Bilski. However, business methods are not found totally ineligible for patents, just this one. But the door is not swung wide open." Florian Mueller sees it differently: "Unfortunately, the Supreme Court delivered an opinion that doesn't help the cause of partial or complete abolition of software patents at all. Within the range of possible ways in which the Supreme Court could justify its decision to affirm the rejection of the relevant patent application, the court's majority position is about the most liberal reasoning that it could have been. Only a decision to grant a patent on the Bilski application could have been any less restrictive. Simply put, the Supreme Court's decision does not do away with even one software patent that already exists, nor does it raise the bar for the future."
