The Supreme Court granted a petition for writ of certiorari on Dec. 6 in a case challenging software method and system patent eligibility under 35 U.S.C. §101, in Alice Corp. Pty. Ltd. v. CLS Bank Int'l ( U.S., No. 13-298, review granted, 12/6/13).The question presented by the patent owner in the case is:Whether claims to computer-implemented inventions--including claims to systems and machines, processes, and items of manufacture--are directed to patent-eligible subject matter within the meaning of 35 U.S.C. §101 as interpreted by this Court? 

The CLS Bank case is controversial because the U.S. Court of Appeals for the Federal Circuit, sitting en banc, failed to reach enough agreement on patent eligibility of computer-related claims to supply precedential jurisprudence. CLS Bank Int'l v. Alice Corp. Pty. Ltd., 717 F.3d 1269, 2013 BL 124940, 106 U.S.P.Q.2d 1696 (Fed. Cir. 2013) (en banc) (92 PTD, 5/13/13).Alice Corp. asserted four patents (U.S. Patent Nos. 5,970,479; 6,912,510; 7,149,720; and 7,725,375) directed to the formulation and trading of risk management contracts against alleged infringer CLS Bank International.The en banc court was 7-3 against patent eligibility of the method claims and 5-5 as to the system claims. Since the lower court had ruled that the system claims were ineligible, that judgment stands and all of Alice's claims are ineligible unless the Supreme Court overturns the decision. Eight members of the en banc court said that method and system or media claims should rise or fall together, but not for the same reasons.
