Liberty Peak Ventures, LLC (LPV), an entity associated with Texas monetization firm Dominion Harbor Enterprises, LLC, has sued MasterCard (1:24-cv-20455) in the Southern District of Florida over products that “facilitate, maintain, transact, authenticate, validate, authorize, clear, settle, and/or process financial data, financial transactions, mobile payments, contactless payments, and/or online payments using Mastercard Transaction Instruments (e.g., Mastercard Cards) and related access to Mastercard’s payment products, methods, and/or services (e.g., solutions, systems, devices, networks, APIs, software development kits, and/or other product solutions)”. Since launching this litigation campaign in July 2021, the plaintiff has sued nine defendants—including Charles Schwab, Comerica, Fiserv, Regions Financial, Visa, and Zions Bancorporation (Amegy Bank National) and asserted 19 former American Express patents, ten in its latest complaint. At issue are features such as compliance with certain EMV standards, RFID technology, and tokenization.
