What was the title of the Wright brothers’ U.S. patent issued in 1906?

The title of the Wright brothers’ U.S. patent issued in 1906 was “Flying-Machine.”

The patent, numbered 821,393, was issued on May 22, 1906, after an application filed in 1903. It described a system for controlling an aircraft in three dimensions rather than claiming only a particular engine or airframe design.

The brothers’ key contribution was coordinated control of roll, pitch, and yaw. Their wing-warping system controlled roll, while a movable rudder helped manage yaw and an elevator controlled pitch. Together, these features allowed a pilot to balance and steer an airplane.

The patent is sometimes incorrectly described as covering the 1903 Flyer alone. Its central legal claim concerned the control method, which could be applied to different aircraft. The patent later became important in disputes involving other American aviation companies and inventors.
