Oracle sued Google over Java APIs for $9B — spent a decade in court and got $0

In January 2010, Oracle completed its $7.4 billion acquisition of Sun Microsystems, gaining ownership of the Java programming language. Seven months later, on 13 August 2010, Oracle sued Google, claiming that Android — Google's mobile operating system — infringed Oracle's copyrights by using 37 Java API packages without a licence. Oracle sought $9 billion in damages, arguing that Google had taken the 'structure, sequence and organization' of the Java APIs.

The case wound through the courts for over a decade. In 2012, district judge William Alsup ruled that APIs were not copyrightable — a landmark decision that sent shockwaves through the software industry. The Federal Circuit reversed in 2014, saying APIs could be copyrighted. A jury then found Google's use was fair use in 2016. The Federal Circuit reversed that too in 2018. Each reversal sent the case back for another round, and Oracle kept pressing its $9 billion claim.

On 5 April 2021, the Supreme Court ruled 6-2 in Google's favour, holding that Google's copying of the Java APIs was a fair use as a matter of law. Justice Stephen Breyer wrote the majority opinion, noting that Google had copied only what was needed to allow programmers to work in a familiar environment. Oracle received zero dollars in damages after eleven years of litigation. The case is now the definitive legal precedent on API copyright and fair use in software.
