Oracle's intellectual property battle against Google has attracted intense interest from software developers, many of whom believe the structure of a programming language should not be subject to copyright protection.
In an appeals brief filed on Monday at the Federal U.S. Circuit Court of Appeals, Oracle said Google's use of Java structure was "decidedly unfair."
"Copyright protects a short poem or even a Chinese menu or jingle," Oracle wrote. "But the copied works here were vastly more original, creative, and labor-intensive."
