(Reuters) - Apple Inc on Tuesday appealed a copyright case it lost against security startup Corellium, which helps researchers examine programs like Apple's planned new method for detecting child sex abuse images.

A federal judge last year rejected Apple's copyright claims against Corellium, which makes a simulated iPhone that researchers use to examine how the tightly restricted devices function.
