Maulsby v. Conzevoy

MATHEWS, Circuit Judge. Appellant brought an action against appellee for infringement of claims 1-5 of patent No. 1,875,077. 1 Appellee filed
an answer and two amended answers. His defenses were that the claims were invalid, and that, if valid, they were not infringed.
The case was tried by the court without a jury. The court held the claims invalid and entered judgment dismissing the action.
From that judgment this appeal is prosecuted.
