Blix amends its lawsuit over the ‘Sign in With Apple’ feature

In October, Blix, the company behind BlueMail — a free email app (pictured)  for iOS, Windows, Linux, and Android — and Followup —a patient communication service — sued Apple over its “Sign in with Apple” feature. Now it’s amended the complaint, according to AppleInsider.

“Sign in with Apple” is, or will be, available on iOS, iPadOS, macOS, and the web. It’s designed to make it easy for users to sign in to their apps and websites using their Apple ID. Instead of filling out forms, verifying email addresses, and choosing new passwords, they can use Sign in with Apple to set up an account and start using your app right away. Apple says that all accounts are protected with two-factor authentication for superior security.

In the October filing with the U.S. District Court for the District of Delaware, Ben Volach, co-founder of Blix, claimed Apple stole BlueMail’s “Share Email” feature for integration in “Sign in with Apple.” 

According to the October suit, Share Email enables users to communicate “using manageable public interaction addresses, without revealing their private interaction addresses.” Volach is suing Apple for patent infringement and illegal monopolization of the App Store, and seeks an injunction, damages and legal fees. In the recent amendment, Blix alleges Apple exerts a monopoly over its various App Stores to artificially suppress the reach of apps competing with apps like Mail.
