Earlier this week, the US Supreme Court released its opinion in the BILSKI ET AL. v. KAPPOS case. The Court affirmed the decision of the Federal Circuit Court of Appeals that the invention in issue, a method of hedging risk, was not-patentable. However, there appears to be some significant disagreement in deciding exactly what the Court decided, as relates to the question of the patentability of business methods. On my reading of judgment, by a majority of 5 to 4, the Court was of the view that pure business methods are not patentable subject matter in the US.
