    Business Methods Patents Survive, But Not Bilski’s Patent
    By a 5-4 vote, the United States Supreme Court has rejected the notion that business methods are categorically unpatentable. By a unanimous vote, however, the Court has affirmed the PTO and Federal Circuit’s rulings rejecting Bilski’s patent claims on methods of hedging commodity risks. The Court also unanimously agreed that while the "machine or transformation" test adopted by the Federal Circuit is a useful indicator of patentability, it is not the sole test for patentability under Section 101 of the Patent Act. Although many had feared--and some had hoped--that all software patents were in jeopardy, the Court’s relatively narrow decision should allay those fears and dash those hopes.
