For the first time in decades, the Supreme Court will take up the dispute over the patentability of software, agreeing on Friday to hear CLS Bank Internationals challenge to a financial software patent held by Alice Corporation Pty Ltd. While the court could end up issuing a narrow decision that only applies to this one case, it opens up the possibility of a broad new precedent on a long-controversial issue. The Supreme Court has previously determined, for instance, that mathematical algorithms are not patentable under law.
