Defendant
2 cases as defendant.
I'll verify the company's profile details.
Citibank, N.A. (Citibank, National Association; commonly "Citibank" or consumer-facing "Citi") is a U.S. national bank headquartered at 388 Greenwich Street, New York, NY. Its institutional lineage traces to the City Bank of New York, founded in 1812; it took the name Citibank, N.A. in 1976. It is an indirect wholly owned subsidiary of Citigroup Inc. (NYSE: C) and is fully consolidated in Citigroup's financial statements; CBNA does not file or publish separate financial statements. It is regulated by the OCC and is a Federal Reserve System member (FDIC certificate #7213).
Products / services. Citibank, N.A. is the principal U.S. bank charter through which Citigroup conducts much of its business, spanning U.S. personal banking (checking and savings accounts, credit cards, mortgages, personal loans), wealth management and private banking, and corporate/institutional services such as Treasury and Trade Solutions, Securities Services, investment banking, and markets trading. For scale, parent Citigroup reported total revenues of $81.1 billion and net income of $12.7 billion for full-year 2024, with approximately 229,000 full-time employees at December 31, 2024 (Citigroup 2024 Form 10-K). CBNA-specific headcount and revenue are not separately disclosed.
Patent-litigation posture. The tracked data show Citibank, N.A. as a defendant in one case and as plaintiff in zero — the profile of an operating company being attacked rather than an active two-way litigant or an assertion entity. The sole tracked suit was filed in the company's home district, the S.D.N.Y., not a plaintiff-friendly venue such as the Eastern District of Texas.
Notable case. Intellectual Ventures I LLC and Intellectual Ventures II LLC v. Citigroup, Inc., Citicorp, and Citibank, N.A., No. 1:14-cv-04638 (S.D.N.Y., filed June 25, 2014, Judge Alvin K. Hellerstein). Plaintiff Intellectual Ventures — a patent aggregation/assertion entity holding acquired patents — asserted five patents directed to cybersecurity and protection of customer payment information. Citigroup's motion to stay pending parallel IV suits against J.P. Morgan Chase and Capital One was denied in December 2014; the case closed in October 2017. The tracked records do not include outcomes on the merits.
Listed in the Stanford NPE Litigation Database as a case involving the '666 patent, with Intellectual Ventures II LLC identified as the patent asserter. The outcome was not confirmed in the narrative.
Cedar Lane Technologies Inc. sued Citibank, N.A. in W.D. Tex. asserting US 8,577,782. The action was voluntarily dismissed with prejudice on 2025-11-20 under Rule 41(a)(1)(A)(i).
