Samuel Blatchford, Gosling v. Roberts — Opinion of the Court
“ There is no suggestion in the specification of the original patent that the plate, E, is to be used, disconnected as its lower end from the step, or to be any other than a yielding plate, so arranged as to keep the door open and shut, in addition to acting as a step-cover and wheel-fender. The first claim of the reissue, if construed so as to cover the defendant's structure, is void for want of novelty, being anticipated by the old structures referred to. Moreover, if so construed, it is invalid as being for a different invention from any invention found in the original patent. ”
