Apple's iOS Simulator Copyright Case Remains Unresolved.

The US Court of Appeals for the Eleventh Circuit ruled that Corellium's CORSEC simulator, which allows security researchers to identify flaws in the iPhone's iOS operating system, is protected by copyright law's fair use doctrine. Apple had sued Corellium in 2019, arguing that its software was a "wholesale copying and reproduction" of iOS and served as a market substitute for its own security research products. The appeals court largely sided with Corellium, stating that its copying of iOS code was transformative and furthered scientific progress. The case has been closely watched by security researchers and digital rights groups.
