X One, Inc. is a private company founded in 2004 by Richard D. Haney and Jose J. Picazo. The company's business centers on developing and licensing intellectual property related to mobile communications. Publicly available information on its specific headquarters location and exact size is limited, though some data services estimate its employee count to be between 10 and 50 people.
X One, Inc. is a non-practicing entity (NPE) that generates revenue by asserting its patent portfolio. It does not manufacture products or offer commercial services. The company's patent portfolio is focused on technology for sharing location data, communications, and mappings between mobile devices, which it describes as "Foundational to the Sharing Economy." The patents asserted in its litigation campaign describe concepts such as a "Buddy Watch application" that allows a mobile device user to add other users to a list to temporarily share their respective locations on a map.
The company's patent-litigation posture is exclusively that of a plaintiff. As of early May 2026, it has been a plaintiff in all eight of its tracked patent infringement lawsuits and has not been named as a defendant. This 8-0 plaintiff-to-defendant record is characteristic of an NPE. The company has frequently filed its cases in jurisdictions considered favorable to patent holders, such as the Eastern District of Texas, where it initiated a new series of lawsuits in April 2026.
X One's most notable litigation was its multi-year campaign against Uber Technologies, Inc., which began in 2016 over patents related to location-detecting technology. The dispute involved proceedings at the district court level, the U.S. Patent and Trademark Office's Patent Trial and Appeal Board, and the Court of Appeals for the Federal Circuit. In April 2026, X One launched a new litigation campaign targeting companies in the food delivery and service industries, filing suits against DoorDash, Domino's Pizza, Pizza Hut, and Neighborfavor, among others.
