that the patent was too abstract. The Court of Appeals for the Federal Circuit upheld Ultramercial's patent, stating that it "does not simply claim the age-old idea that advertising can serve as currency. Instead [it] discloses a practical application of this idea." The court also asserted that the technical elements required to implement the system described were intricate enough to not be abstract. On June 21, 2013, after being ordered by the Supreme Court to re-examine the case, the Federal Circuit upheld its decision and ruled that Ultramercial's patents were valid. However, the 2014 Supreme Court ruling in Alice Corp. v. CLS Bank Int'l narrowed patent eligibility for software, and the Supreme Court subsequently sent Ultramercial's case back to the Federal Circuit. In November 2014, the Federal Circuit invalidated Ultramercial's patent in light of the ruling in Alice, undoing two of its own previous rulings and freeing WildTangent from liability.
