eBay

eBay Inc., commonly known as eBay, is an American multinational e-commerce company headquartered in San Jose, California, USA. Founded by Pierre Omidyar in September 1995, the company became publicly traded on NASDAQ under the ticker symbol EBAY. As of 2025, eBay had approximately 12,300 employees and reported approximately $11.1 billion in annual revenue. Its market capitalization was approximately $49 billion as of May 2026.

eBay operates global online marketplace platforms that connect millions of buyers and sellers in over 190 markets worldwide. The platform facilitates the buying and selling of new and used items through both online auctions and "Buy It Now" fixed-price listings. Its extensive product categories span electronics, vehicles, fashion, collectibles, sports trading cards, home and garden items, and more. The company generates revenue primarily through commissions charged to sellers on successful sales.

In terms of patent litigation, eBay appears to primarily maintain a defensive posture. The provided case data indicates no instances where eBay has acted as a plaintiff. Instead, it has been named as a defendant in one tracked case. This suggests that eBay is an operating company defending against patent assertion entity (NPE) suits rather than actively asserting its own patent portfolio.

The notable tracked case involving eBay is Sampo IP, LLC v. eBay, where eBay was the defendant. This case was filed on February 10, 2014, in the United States District Court of Delaware.
