On February 8, 2013, the Federal Circuit, sitting en banc, heard oral arguments in CLS Bank International v. Alice Corporation Pty. Ltd., No. 2011-1301, which vacated a panel opinion from the Federal Circuit, CLS Bank Int’l v. Alice Corp., 685 F.3d 1341 (Fed. Cir. 2012), vacated, 484 Fed. Appx. 559. The current appeal arises from a grant of summary judgment from the U.S. District Court for the District of Columbia that the asserted claims of Alice Corporation’s (Alice) patents are invalid for failing to claim patent-eligible subject matter under 35 U.S.C. § 101, CLS Bank Int’l v. Alice Corp., 768 F. Supp. 2d 221 (D.D.C. 2011).
