Google today formally responded to Oracle's anti-Android lawsuit by motioning to dismiss the case. The search firm accused Oracle of violating the "doctrine of unclean hands" by willingly changing its approach after buying Sun. Oracle as late as 2009 had been calling for Sun to open-source the Java code at the heart of the suit but, having acquired Sun, is now refusing to do the same and suing now that it has a vested interest in profiting from patent disputes.
