Capital One

Capital One Financial Corporation, commonly known as Capital One, is an American bank holding company headquartered in McLean, Virginia. Founded in 1994 as a spin-off from Signet Financial Corp., it became a publicly traded entity on the New York Stock Exchange (NYSE: COF). As of December 31, 2025, Capital One had 76,300 employees and reported annual revenue of $69.252 billion for 2025, increasing to $75.164 billion for the twelve months ending March 31, 2026. The company's ownership is predominantly held by institutional investors, with Vanguard Group Inc. and BlackRock, Inc. being major shareholders.

Capital One provides a broad array of financial products and services to consumers, small businesses, and commercial clients in the United States, Canada, and the United Kingdom. Its major offerings include credit cards (for which it is the largest issuer in the U.S.), checking and savings accounts, auto loans, and commercial banking services. The company has approximately 750 bank branches, including over 60 café-style locations, and 7,000 ATMs in the United States. Capital One also owns the Discover Card, Diners Club, and Pulse payment networks.

In terms of patent litigation, Capital One primarily operates as a defending company, often facing assertions from Non-Practicing Entities (NPEs). The provided case data shows Capital One as a plaintiff in one case before the Patent Trial and Appeal Board (PTAB), Capital One v. Wapp Tech Corp. This posture suggests that Capital One utilizes PTAB inter partes reviews (IPRs) to challenge the validity of patents, a common strategy for operating companies to proactively address patent threats.

Historically, Capital One has been a target of patent infringement suits. For example, Intellectual Ventures, often characterized as a patent assertion entity, brought multiple suits against Capital One concerning patents related to retail banking technologies, mobile banking, and back-end database systems. Capital One successfully defended against some of these claims, with some patents being dismissed or found ineligible. Capital One also brought antitrust counterclaims against Intellectual Ventures in some of these cases, alleging monopolization. In another recent instance, MCOM IP, LLC filed a patent infringement action against Capital One in the Western District of Texas in 2023 concerning e-banking touch points, which was voluntarily dismissed without prejudice by MCOM IP in 2024.
