Oracle America, Inc. owns the copyright to the Java computer language. In 2005, Google LLC acquired Android and wanted to build a new software platform for mobile devices. To allow the programmers familiar with Java to help build the platform, Google copied about 11,500 lines of code from the Java program. These lines of code are part of a programming tool called that’s called an “Application Programming Interface (API)”. 

Oracle sued for copyright infringement.

You don’t need an Oracle to predict the outcome of working outside the scope of a license. %CUT% Rimini Street, Inc. was hired by one of Oracle USA, Inc.’s licensees to develop and test updates for the licensee’s customers. But Rimini started using Oracle’s software to develop products for its other clients who didn’t have a license from Oracle. Oracle sued and won a copyright infringement judgment. Rimini appealed and lost at the 9th Circuit Court of Appeals. Rimini had two interesting affirmative defenses that were rejected by the court. First, Rimini said it had an express license. While it had an express license with respect to a single licensee, it didn’t have a blanket express license to use the software for anyone else. Second, Rimini argued that Oracle was misusing the copyright. Copyright misuse is an equitable defense against copyright infringement allowing copyright infringers to avoid infringement liability if the copyright holder has engaged in abusive or improper conduct in exploiting or enforcing the copyright. In other words, Rimini was accusing Oracle of being a copyright bully because Oracle wasn’t allowing Rimini to get a head start with Oracle’s future software licensees. The court rejected this argument. As the owner of the software, Oracle had every right to control the use of its software by potential future licensees.
