Walmart Inc. is a publicly traded multinational retail corporation headquartered in Bentonville, Arkansas. Founded by Sam Walton in 1962, the company is listed on the New York Stock Exchange under the ticker WMT. It is one of the world's largest companies by revenue, reporting $681 billion for the 2025 fiscal year, and is the largest private employer globally with approximately 2.1 million employees. While a public company, the Walton family retains a controlling interest of about 45% through their holding companies and trusts.
Walmart operates a vast chain of hypermarkets, discount department stores, and grocery stores. Its primary retail brands are Walmart and Sam's Club, a chain of membership-only retail warehouses. The company's offerings span a wide array of product categories, including groceries, apparel, home goods, electronics, and pharmacy products. In addition to retail sales, Walmart provides services such as in-store Auto Care Centers, financial services like money transfers and credit cards, pharmacy and health services, and photo printing.
The company's patent litigation history shows it as a defendant in all three tracked cases and a plaintiff in none. This posture is typical of a large operating company defending its products and services against patent assertions. The cases have been filed in the U.S. District Courts for the Eastern and Southern Districts of Texas, venues frequently used by patent plaintiffs.
The tracked lawsuits against Walmart were filed by non-practicing entities (NPEs) or companies focused on patent monetization.
