On September 2, 2014, Federal Circuit Judge William Bryson, sitting by designation in the Eastern District of Texas, ruled that two patents on a computer-based method for converting airline customers’ loyalty reward credits are invalid for claiming only an abstract idea under the U.S. Supreme Court’s rulings in Alice Corp. Pty. Ltd. v. CLS Bank Int’l and Bilski v. Kappos. Plaintiff Loyalty Conversion Services sued ten major airlines claiming their frequent flyer programs infringed U.S. Patent numbers 8,313,023 and 8,511,550 which cover a method in which a company accepts transfers of credits to “independent funds.” The suits targeted the airlines’ various hotel-to-mile partnerships, which allow customers to convert hotel points to airline miles. Judge Bryson ruled that the patents were invalid under Alice and Bilski because the role of a computer in the claims of the patents was limited to the basic functions of a generic computer that were so simple that they could be performed by a human being without the aid of a computer of any kind. The court characterized the patents to claim “the unpatentable concept of currency exchange, as applied to the exchange of currencies in the form of loyalty award credits of different vendors.” Therefore, the patents were invalid because they “do not contain an ‘inventive concept’ that solves practical problems and ensures that the patent is directed at something ‘significantly more than’ the ineligible abstract idea itself.”
