Patently-O has a great round-up of the amicus briefs filed in the Bilski v. Doll case. The Supreme Court should certainly hear this case and clarify the rule in this matter. This is a decision that will have a huge impact on business. The ability to patent software is considered very important by those in the business, which is evidenced by the fact that software patent applications still take quite a while to get through the PTO. I look forward to the Supreme Court's decision.
