Software patents—and questions about whether software should actually be patentable at all—have always been a bone of contention among patent professionals. Now the Supreme Court has taken up the issue in Alice Corp. Pty. Ltd. v. CLS Bank International.

The Alice case is the latest in an encouraging trend by the Court to take a more active role in defining and sharpening interpretation of patent law. Overall, this is good news and has the potential to help evolve toward a more predictable patent system.
