On May 10, 2013, the Federal Circuit, sitting en banc, handed down its opinion in CLS Bank Int’l v. Alice Corp., No. 2011-1301, slip op. (Fed. Cir. May 10, 2013). The majority of the Federal Circuit judges agreed on little other than that the method and computer-readable medium claims involved in the dispute were patent ineligible. Essentially, Alice Corporation owned patents that the Federal Circuit found to be nothing more than abstract ideas based on use of escrow accounts and record keeping associated with the settling of transactions. However, the Court failed to agree on the reasoning as to why such claims were ineligible subject matter with the judges evenly split regarding the eligibility of comparable computer systems claims.
