In August 2020, Illinois NPE Authwallet LLC voluntarily dismissed a case against Visa, the first suit in its sole litigation campaign launched last June. Authwallet has now added cases against American Express (1:21-cv-03219) in the Southern District of New York and Citigroup (4:21-cv-01203) in the Southern District of Texas. The plaintiff asserts in each complaint a single patent generally related to processing financial transaction data with certain “processing rules”, with the defendants accused of infringement through the provision of their respective cardholder reward programs. At issue are features for notifying users of transactions where discounts and/or credits can be applied.
