Valve Corporation

Valve Corporation is a privately held American video game developer, publisher, and digital distribution company headquartered in Bellevue, Washington. Founded in 1996 by former Microsoft employees Gabe Newell and Mike Harrington, the company is also known as Valve Software. As a private entity, its financial details are not fully public, but reports from 2025 suggested annual revenues in the billions of dollars, with an employee count estimated to be between 330 and 360. Gabe Newell is the majority owner.

Valve is a major operating company in the video game industry. Its most significant operation is the Steam digital distribution platform, which is the largest for PC gaming, launched in 2003. The company develops and publishes several of the most popular and critically acclaimed video game franchises, including Half-Life, Counter-Strike, Portal, Team Fortress, and Dota 2. In addition to software, Valve develops its own hardware, including the Valve Index virtual reality headset and the Steam Deck, a portable handheld gaming computer.

As an operating company, Valve's patent litigation history primarily shows it defending its technology. The provided data indicates Valve has been a defendant in two lawsuits and a plaintiff in one administrative patent challenge at the Patent Trial and Appeal Board (PTAB). This posture, with more cases as a defendant than as a plaintiff, is typical for a technology company that develops and sells its own products and services. The cases are filed in various federal courts, not concentrated in any single district known for patent litigation.

The tracked cases highlight disputes over hardware technology. The suit brought by Ironburg Inventions Ltd. concerned patents related to game controllers, which Valve challenged in a corresponding PTAB proceeding. The more recent case, Atlas Global Technologies LLC v. Valve Corporation, is an example of Valve being targeted by a patent assertion entity in the U.S. District Court for the Western District of Texas.
