He got a patent for the development on this date in 1858. Lipman's early version was a pencil with a groove at the top, into which he glued an eraser. He sold his patent in 1862; the US Supreme Court later invalidated it, saying that since combining a pencil with an eraser did not change the function of either item, the pencil-with-eraser could not be patented.
