A unanimous Supreme Court decision in Alice Corporation Pty. Ltd. v. CLS Bank International ruled that the patent claims were not eligible under 35 U.S.C. § 101, as they were deemed abstract ideas without significant additional features. This memorandum provides preliminary instructions for the patent examining corps to evaluate claims involving abstract ideas, emphasizing a two-part analysis to determine eligibility. The analysis now applies uniformly to all judicial exceptions and categories of claims, replacing earlier differing guidelines.
