1 the Supreme Court, in a 6–2 decision 2 written by Justice Breyer, held that Google’s copying of Oracle’s Java application programming interface (API) naming convention was a fair use as a matter of law. The Court concluded that Google made a “transformative use” of the software and had only used a relatively small amount of it. Oracle’s Java APIs (created by Sun Microsystems, which was later purchased by Oracle) comprised set packages of Java software so programmers could easily access frequently used functions instead of rewriting them each time. Google copied 37 of the API packages. The Court concluded that Google thought Java application programmers would want to use the same 37 sets of functionalities in the new Android operating system using the same names as used in Java. Google then copied the declaring source code from the 37 Java API packages, including all the names of methods, classes, interfaces and packages covering the 37 API packages, with over 600 classes and 6,000 methods. Google inserted that source code into its Android software.
