Yahoo Inc. is the latest big-name corporation to be hit with a patent infringement suit in New Jersey federal court by Nevada-based Verify Smart Corp. over online identity verification technology.

Yahoo’s system for allowing online account holders to verify their identities by having a four-digit passcode sent to their cellphones infringes Verify Smart’s ’648 patent, which “is directed to novel systems and methods of verifying the identity of consumers initiating electronic transactions to provide enhanced security for such transactions,” according to the complaint filed Nov. 7.
