Inventor Mary Anderson received a patent for her car-window cleaning device in 1903. Anderson's invention came about during a trip to New York City when the Alabama-born inventor noticed that streetcar drivers had to open the windows of their cars when it rained in order to see.
But carmakers eventually began offering intermittent wipers. Mr. Kearns sued the Ford Motor Company in 1978 and Chrysler in 1982, accusing them of patent infringement. In 1990, a jury decided that Ford had infringed on Mr. Kearns's patent, though it concluded that the infringement had not been deliberate.
