Apple fails to fully reboot iOS simulator copyright case

Apple Inc. failed to fully revive a long-running copyright lawsuit against cybersecurity firm Corellium Inc. over its software that simulates the iPhone's iOS operating systems, letting security researchers identify flaws in the software.

The US Court of Appeals for the Eleventh Circuit on Monday ruled that Corellium's CORSEC simulator is protected by copyright law's fair use doctrine, which allows the duplication of copyrighted work under certain circumstances.

CORSEC furthers scientific progress by allowing security research into important operating systems," a three-judge panel for the appeals court said, adding that iOS is functional operating software that falls outside copyright's core."

Good.
