The dust finally settled in the decade-long Oracle case against Google's Android system Java source code infringement case. The US Supreme Court ruled this Monday that Google did not infringe.

Earlier, Oracle sued Google for copying more than 11,000 lines of its Java API source code to develop the Android system, and filed a claim of 9 billion US dollars for this.However, Google refused to pay this compensation, believing that the use of the relevant code falls within the scope of fair use, so there is no copyright liability.

This time, the Supreme Court passed the ruling that Google was not infringed by a ratio of 6 votes in favor and 2 against.

For Google to use part of the Sun Java API to create a new platform that is easy for program developers to use,This is in line with the basic constitutional goal of copyright itself — the principle of “creative progress.”

Furthermore, Justice Breyer of the court said in his judgment that the amount of code copied by Google only accounted for 0.4% of the total 2.86 million lines of code in the Java API, which is equivalent to “the accelerator pedal that powers the car in a vehicle, or a QWERTY keyboard with words appearing on the keys on a standard typewriter.”
