"Today, after a wait of nearly 8 months the Supreme Court has seemingly got it right […]. In doing away with the machine or transformation test as the sole test for determining whether an invention is patentable subject matter the Supreme Court has kicked open the door and will not allow it to be closed on new technologies and innovations that we cannot today imagine. Processes have always been patentable and there is no justifiable reason to require a process to be tied to a machine in order to be patentable. Similarly, there is no justifiable reason to exclude business methods from being considered patentable subject matter. So once again, it seems an expansive vision of what suffices as patentable subject matter prevails."
"The Supreme Court held that the machine-or-transformation test is not the sole test for patent eligibility under §101, and that the Federal Circuit erred when it ruled that it was the singular test to determine whether an invention is patentable subject matter. […] The Court explained that under Benson, Flook, and Diehr, the Bilski claims are not direct to a patentable process but rather attempts to patent abstract ideas. The Bilski claims covered unpatentable abstract ideas, just like the algorithms at issue in Benson and Flook."
"There were no dissents, only concurring opinions, which is in and of itself a little surprising, at least at first glance until you realize that the Justices all agreed Bilski’s invention ought not to be patentable, but some, such as Justices Stevens and Breyer would have found all business methods unpatentable."
