The Supreme Court has issued its opinion in Bilski v. Kappos. In the decision, the Supreme Court affirmed that Bilski’s risk-management method was not the type of innovation that may be patented. However, rather than using the Federal Circuit's "machine-or-transformation test", the court simply relied on prior precedent to find the claimed method unpatentably abstract. Justice Kennedy authored the majority opinion. Justices Breyer and Stevens both wrote concurring opinions.
