Amazon.com, Inc.
Amazon.com, Inc. is a publicly traded multinational technology company founded by Jeff Bezos in 1994. Headquartered in Seattle, Washington, with a second major office in Arlington, Virginia, the company trades on the NASDAQ stock exchange under the ticker symbol AMZN. As one of the world's largest companies, Amazon reported annual revenue of approximately $717 billion for 2025 and employs over 1.5 million people globally. Its market capitalization was approximately $2.9 trillion as of May 2026.
Amazon operates a diverse and extensive portfolio of businesses. It is best known as the world's largest online retailer and marketplace, offering a vast range of products from books and electronics to groceries and apparel. A major division is Amazon Web Services (AWS), the world's leading provider of cloud computing services. The company also manufactures and sells consumer electronics, including Kindle e-readers, Fire tablets, and Echo smart speakers powered by its Alexa artificial intelligence assistant. Furthermore, Amazon has a significant presence in digital streaming through services like Prime Video and Twitch, and operates physical retail stores, most notably Whole Foods Market.
The company’s patent litigation history shows it is primarily a defendant. The provided data indicates Amazon has been a defendant in 13 of its 15 tracked cases, positioning it as a frequent target of patent infringement lawsuits, a common posture for a large operating company. These suits have been filed in various U.S. District Courts, including frequent patent litigation venues like the Western and Eastern Districts of Texas and the District of Delaware. Amazon has only been a plaintiff in two tracked cases, which were actions before the U.S. Patent and Trademark Office's Patent Trial and Appeal Board, suggesting a defensive use of the patent system to challenge the validity of asserted patents.
The case list shows Amazon defending against suits from various patent assertion entities. For example, it has faced multiple lawsuits from entities associated with AlmondNet, Inc. concerning online advertising technology. Other plaintiffs include IOT Innovations LLC, Atlas Global Technologies LLC, and VB Assets, LLC. The lawsuit initiated by Twitch Interactive, Inc., an Amazon subsidiary, against NL Giken Inc. is an example of the company proactively challenging patents that may affect its streaming services.
