Overview

The Supreme Court held in 2021 that Google's particular copying of Java API declaring code was fair use. Justice Stephen Breyer emphasized programmers' skills and a new computing environment. Justice Clarence Thomas argued that the copying displaced Oracle's licensing market.

Read the full background

The April 5, 2021 opinion (opens in a new tab) holds that the copying at issue was fair use, assuming copyrightability for purposes of the analysis. The Court ruled 6-2; Justice Barrett did not participate.

Breyer's majority emphasizes the function of the declaring code, programmers' acquired skills and use in a new computing environment. Thomas, joined by Alito, argues that the copying harmed Oracle's licensing opportunities and that the majority weakened protection for computer code.

Oracle's statement (opens in a new tab) criticizes the competition effects. The ruling does not decide that all APIs lack copyright protection or resolve whether copying creative works to train AI is fair use.
