in 1963, the first modern intermittent wipers were invented by Robert Kearns, an engineering professor at Wayne State University in Detroit, Michigan.
The road to intermittent wipers began earlier, on his wedding night in 1953, when an errant champagne cork shot into Kearn's left eye, which eventually went almost completely blind.
Nearly a decade later, Kearns was driving his Ford Galaxie through a light rain, and the constant movement of the wiper blades irritated his already troubled vision. He got to thinking about the human eye, which has its own kind of wiper, the eyelid, that automatically closes and opens every few seconds.
Finally in 1963, Kearns put his idea into action, building the first intermittent wiper system using off-the-shelf electronic components. Kearns showed it to the Ford Motor Company, and proposed manufacturing the design.

Patent infringement is the commission of a prohibited act with respect to a patented invention without permission from the patent holder. Permission may typically be granted in the form of a license. The definition of patent infringement may vary by jurisdiction, but it typically includes using or selling the patented invention.
