ERROR TO THE CIRCUIT COURT OF THE UNITED STATES FOR THE WESTERN DISTRICT OF WISCONSIN.delivered the opinion of the court.
This is an action at law, brought in the Circuit Court of. the United States for the Western District of Wisconsin, by Sarah
The plaintiff put in her title, being the same papers as in No. 61, and then Luther V. Moulton, the same witness as in No. 61, testified as follows: “ I live at Grand Bapids, Michigan; am a partner in a foundry there. I have had experience in mechanics and patents ; have photographed models; have been consulted about the patentability of mechanical devices; have been an expert witness in patent causes; have done patent soliciting; have examined and am acquainted with the May patent in suit; know its specifications and claims, and am acquainted with its practical operation and effect. I have examined the jail of the defendant county and the cells therein and the device there in use for fastening the doors of the cells, its arrangement and method of operation. Such device contains, in my opinion, the mechanical equivalent of the so-called May patent. It is substantially the Same thing as the device described in the specification and claims of the patent in question, except the second and third claims. The results produced by the combinations claimed in the patent, so far as they relate
The plaintiff then gave evidence tehding to show that the patented device was useful and economical, and had been in use in many jails and prisons since it was patented. It was admitted that the device was put into the jail of the defendant in 1878, and had been in use there ever since. Other evidence was put in on the part of the defendant, including a stipulation signed by the attorneys for the- respective parties, setting forth that, prior to October 5, 1859, a device or contrivance
At the close of the testimony on both sides, the defendant moved the court to direct a verdict for the defendant on the grounds (1) that the defendant was merely a territorial division of the State, existing only as a political subdivision thereof, and could not be sued for the infringement of a patent; .(2) that the right of action in the suit had never been assigned to the plaintiff. The court sustained the motion on'both grounds, ( 30 Fed. Rep. 241 ,) and directed the jury to return, a verdict for the defendant, which was done. The plaintiff excepted to the'ruling and to the direction.
On the grounds set forth in the opinion in No. 61 Fond du Lac County v. May, ante, 395, the patent was invalid, and the judgment must be affirmed. This defence .was set up- in • the answer, and the motion to direct a verdict for the defendant was broad enough to cover the question of the invalidity of the patent, although that ground was not then distinctly urged. Want of patentability is a defence, though not set up in an answer or plea. Brown v. Piper, 91 U. S. 37 , 44; Dunbar v. Myers, 94 U. S. 187 ; Slawson v. Grand Street Railroad Co., 107 U.
