In <i>CLS Bank,</i> the Federal Circuit Agrees to Disagree

By Scott F. Llewellyn and Jason D. Hall
July 02, 2013

The intellectual property community hoped and expected that the Federal Circuit's en banc decision in CLS Bank Int'l v. Alice Corp. would provide guidance regarding the scope of patentable subject matter under 35 U.S.C. ' 101. Instead, the Federal Circuit's decision created confusion, identifying three competing tests for assessing patentable subject matter under ' 101.

The Federal Circuit's decision included seven separate opinions spanning 135 pages, but the only precedential portion appears to be the one-page per curiam opinion affirming the district court's holding that the asserted method, computer-readable medium, and system claims are not directed to patent-eligible subject matter. Many of the judges agreed on the ultimate result, with seven out of 10 concluding that the asserted method and computer-readable medium claims were patent-ineligible, and five of those seven judges concluding that the system claims were patent-ineligible. But the Federal Circuit was unable to resolve some of the most important issues the case presented.

For example, the decision failed to provide a framework for determining what is an “abstract idea,” including whether a computer-implemented invention is a patent-ineligible “abstract idea.” The decision also failed to provide guidance regarding whether the type of claim affects patent eligibility under ' 101, including the related question of whether the presence of a computer is sufficient to provide patent eligibility. And the Federal Circuit's identification of three different tests for patentable subject matter raises a new issue for courts to consider: whether the analysis of patent eligibility turns on the entire claim, or only the portion of the claim that goes beyond a mere “abstract idea.”

The Stranger to the Deed Rule Image

In 1987, a unanimous Court of Appeals reaffirmed the vitality of the "stranger to the deed" rule, which holds that if a grantor executes a deed to a grantee purporting to create an easement in a third party, the easement is invalid. Daniello v. Wagner, decided by the Second Department on November 29th, makes it clear that not all grantors (or their lawyers) have received the Court of Appeals' message, suggesting that the rule needs re-examination.
