Friday, April 9, 2021 In a narrowly drawn, yet significant decision, the Supreme Court reversed the Federal Circuit and ruled that Google LLC’s (“Google”) copying of some of the Sun Java Application Programming Interface (API) declaring code was a fair use as a matter of law, ending Oracle America Inc.’s (“Oracle”) infringement claims over Google’s use of portions of the Java API code in the Android mobile platform. ( Google LLC v. Oracle America, Inc., No. 18-956, 593 U.S. ___ (Apr. 5, 2021)). In reversing the 2018 Federal Circuit decision that found Google’s use of the Java API packages was not fair use, the Supreme Court, in a 6-2 decision (Justice Barrett did not take part in the case) found where Google reimplemented the Java user interface, taking only what was needed to allow outside developers to work in a new and transformative mobile smartphone program, Google’s copying of the Sun Java API was a fair use as a matter of law. This decade-long dispute had been previously dubbed “The World Series of IP cases” by the trial court judge, and like many classic series, this one culminated in a winner-take-all Game 7 at the highest court.
