Two-Factor Authentication Campaign Spreads Beyond Banks

February 22, 2023

The second round of cases filed in the two-factor authentication campaign of Dynapass IP Holdings LLC indicates that the plaintiff has moved beyond accusations against just financial institutions. Last June, Dynapass sued nine such defendants, adding five more last week—one filed against each of Charles Schwab (2:23-cv-00064), East West Bancorp (East West Bank) (2:23-cv-00065), Experian (Experian Marketing Solutions) (2:23-cv-00066), First Citizens Bancshares (First Citizens Bank and Trust) (2:23-cv-00067), and Simmons First National (Simmons Bank) (2:23-cv-00068)—but also targeting Amazon (2:23-cv-00063) with the same expired patent. Three of the nine prior cases, all consolidated before Eastern District of Texas Judge Rodney Gilstrap, have ended, each after a noticed settlement.
