The patent world was tossed into confusion at the Bilski decision. In its aftermath, there was a lot of debating about the implications. What became clear from those discussions is that nobody was satisfied with the outcome and wanted more clarity.
Yesterday the case went to the Supreme Court. It seems to be a high-energy event. The judges have obviously prepared themselves and immediately fired probing questions at both sides of the case.
The world awaits wisdom.
