Nintendo invented the directional pad. That small plastic cross first appeared on the Game & Watch Donkey Kong in 1982, designed by Gunpei Yokoi. US patent: US4,687,200 (Google Patents).
Forcing Alternatives
During the patent period, competitors could not use the same D-pad construction without a license. This drove hardware differentiation: Sega, Sony, and others developed alternative directional input solutions. The patent constrained imitation while diversifying the industry.
The Microsoft Dispute
In 2008, Microsoft obtained a patent on a revised D-pad design for Xbox 360. Nintendo filed a complaint with the US International Trade Commission. The companies reached a cross-licensing agreement in 2012 — a common resolution when both parties hold overlapping portfolios.
Scale of a Small Invention
A small plastic cross generated licensing negotiations and competitive responses across the entire game hardware industry for twenty years. Patent impact is determined not by physical size, but by universality and difficulty of substitution.
