Since the Supreme Court decided Alice v. CLS Bank in June 2014, the USPTO regularly issued new memoranda explaining its implementation of the § 101 framework. This includes some of the more notable memos for prosecutors: the memo on Enfish v. Microsoft from May 2016, the memo on McRO and BASCOM from November 2016, and dozens of eligibility examples. Much of that guidance is incorporated into the MPEP. While the guidance does not have the force of law, patent examiners are expected to follow it.
