Labor Saving Device
To be patented, an invention must be novel, non-obvious, and useful. Contrary to popular belief, this does not mean that someone must be capable (or willing) to use it. In 1965, George and Charlotte Blonsky patented their "Apparatus for facilitating the birth of a child by centrifugal force" — U.S. Patent No. 3,216,423.
