Second Bank Sued in Multi-Factor Authentication Campaign

October 27, 2021

Texas Secure Authentication, LLC has sued a second bank in the Western District of Texas. Last November the inventor-controlled plaintiff hit FCT Bancshares (First National Bank of Central Texas) with a single patent generally related to determining identification through multiple information containers and registers. Little happened through dismissal of that case, without prejudice, in early June 2021; now, Texas Secure has sued Cullen/Frost Bankers (Frost Bank) (6:21-cv-01069) over the same patent, with infringement allegations again targeting the use of multi-factor authentication methods in online banking and Internet services.
