Google's Android operating system is the world's best-selling smartphone platform. Oracle sued Google in 2010, claiming that Google had improperly incorporated parts of Java into Android. Oracle is seeking roughly $1 billion on its copyright claims.A jury ultimately cleared Google on the patent-infringement charges but found that the Android source code did infringe on Oracle's copyrighted code.
On June 20, 2012, district court entered final judgment in favor of Google and against Oracle on its claim for copyright infringement. In Its final judgment the US Appeals court has observed that "It is undisputed that the Java programming language is open and free for anyone to use. Except to the limited extent noted below regarding three of the API packages, it is also undisputed that Google could have written its own API packages using the Java language. Google chose not to do that. Instead, it is undisputed that Google copied 7,000 lines of declaring code and generally replicated the overall structure, sequence, and organization of Oracle’s 37 Java API packages."
