"Samsung appears to be no less determined to fight. Apple's supplemental infringement contentions targeting the Android 4.0 lead device are an unequivocal signal to Google that Apple doesn't shy away from a frontal assault."
Meanwhile, on Friday, a German court also threw out Samsung's assertions that the iPhone infringes upon one of its 3G patents.
