Typically, consumers and developers have been required to purchase expensive Apple hardware to access iOS. Corellium’s virtual machines raise concerns that developers could test apps without acquiring the necessary hardware.
The US Court of Appeals for the Eleventh Circuit ruled that Corellium’s CORSEC simulator is protected under the fair use doctrine of copyright law. This ruling is based on the “duplication of copyrighted work under certain circumstances.” Corellium argues that its simulator primarily serves researchers, federal agencies, and defense contractors, highlighting the distinctions between its product and the regular distribution of iOS.
