Apple Inc. has beaten back class certification in a long-running lawsuit accusing the company of misleading consumers about the security of the personal information stored on the company’s mobile devices.

On Tuesday, U.S. District Judge Jon Tigar of the Northern District of California found consumers “failed to demonstrate that Apple’s privacy-related marketing was sufficiently extensive to support an inference of class-wide exposure” on their false advertising-related claims. The judge also found the plaintiffs hadn’t demonstrated a feasible way to calculate damages based on their theory of liability.
