    The US Court of Appeals for the Federal Circuit affirmed without comment a Delaware federal court’s decision to dismiss the case last year.

    Blix’s 2019 lawsuit said Apple had copied patented features of its BlueMail app in “Sign In With Apple,” which allows users to sign in to third-party applications and websites with Apple IDs.

    Blix also accused Apple of violating antitrust law by forcing app developers that offer a third-party SSO to also offer “Sign In With Apple” and using monopoly power to build a “moat” around its user base by making it difficult and expensive to leave its iOS operating system.

    US District Judge Leonard Stark dismissed Blix’s allegations last year, invalidating Blix’s patent and finding the company did not explain how Apple was “eliminating competition in any market.”

    Blix had argued on appeal that Stark disregarded an “entire pattern of anticompetitive conduct” from Apple, including what Blix called Apple’s “hostile” actions toward it and its alleged practice of “Sherlocking,” using its third-party app review process to steal developers’ ideas.
