Attorney E. Joshua Rosenkranz represented Oracle at Supreme Court oral arguments last year. WASHINGTON (CN) — Fair-use doctrine supports Google engineers who copied at least ten of thousands of lines of code when they created the Android mobile operating system, the U.S. Supreme Court ruled Monday. In a case at once about open-source software and market domination, the 6-2 decision marks an $8.8 billion defeat for Oracle America. The software giant sought the massive damages award after Google used the ubiquitous computer programming language Java without a license to create what is now the biggest mobile operating system in the world.
