In the most expansive interpretation of software copyright law since Whelan v. Jaslow, Judge O’Malley in Oracle v. Google endorsed dual protection for APIs from both copyright and patent law. This ignored an important statement from that court’s earlier ruling in Atari Games v. Nintendo that “patent and copyright laws protect distinct aspects of a computer program.”
