Last October, inventor-controlled Textile Computer Systems, Inc. (TCSI) returned to litigation, suing Broadway National Bank, Charles Schwab, Comerica Bank, Cullen/Frost Bankers (Frost Bank), Independent Bank, International Bank of Commerce, Southside Bank, Texas Capital Bank, Vantage Bank Texas, and WoodForest Financial, all in the Western District of Texas. Now, TCSI has fired off another round of complaints in the same district, hitting Amarillo National Bank, Jefferson Bank, Regions Financial, Truist Financial (Truist Bank), Trustee Cadence Bank, US Bancorp (WestStar Bank), and Zions Bancorporation. While five patents were asserted last year, only four appear in these new complaints; review of a claim construction order handed down by District Judge Alan D. Albright on September 6, 2022 might explain the drop.

As recently reported by RPX in its Q4 in Review, NPE litigation targeting the Financial Services sector rose in 2021, with double the number of defendants added to litigation compared to 2020. The plaintiffs active in this sector today include several inventor-controlled NPEs, a publicly traded patent assertion entity, two Texas-based monetization firms, and multiple prolific litigants.

Inventor-controlled Textile Computer Systems, Inc. has turned one case into a campaign by filing new suits against two more credit unions, Fort Worth City Credit Union (2:16-cv-01048) and Sabine Federal Credit Union (2:16-cv-01047). Textile Computer Systems hit East Texas Professional Credit Union (2:16-cv-00702) this past July, with all three complaints asserting two patents (8,505,079; 8,533,802) generally related to authentication in online communications. The accused products are authentication systems used in connection with credit and debit cards.
