Supreme Court of the United States February 18, 1875 (Littlefield v. Perry)

The CHIEF JUSTICE

delivered the opinion of the court.

We are met at the outset of this case with a question of jurisdiction. All the parties, plaintiff as well as defendant, are citizens of the State of New York. The power of the Circuit Court, therefore, to entertain the cause, if it exists at all, must be found in the jurisdiction conferred by the patent laws.
