The Wright brothers patented the mechanism that let an airplane bank and turn, then spent nearly a decade suing everyone who built a flying machine that could do the same thing, including the war effort that needed them.

The Wright brothers patented a flight-control system in 1906 built around wing warping, twisting the wingtips to bank the aircraft. Glenn Curtiss developed a separate method using hinged surfaces, ailerons, to achieve the same lateral control, and publicly demonstrated it a couple of years later.
The Wright Company sued Curtiss and other manufacturers for patent infringement starting in 1909, arguing the patent covered the underlying principle of lateral control regardless of the specific mechanism. [VERIFIED] A federal appeals court ruled in the Wright Company's favor in January 1914, affirming that its patent extended to functionally similar aileron systems.
