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.

Google avoided the ignominious fate of losing its trademark due to genericide. %CUT% Trademark protection extinguishes when the trademark becomes interchangeable with the name of the product or service. This process is called “genericide”. Some famous examples of genericide are aspirin for pain reliever, cellophane for plastic wrap and thermos for a vacuum flask. Two people filed a proceeding with the Trademark Trial and Appeal Board (TTAB) to cancel the Google trademark due to it having become a generic word for searching on the Internet. The TTAB denied the cancellation and the plaintiffs appealed to the Ninth Circuit Court of Appeals. The Court affirmed the TTAB. The Court’s opinion stated that even though the public might use the term as a verb, the Google mark could still serve as a source identifier.
