et aI. v. HYATT. (Circuit Court of Appeals. Ninth Circuit. June 27, 1895.) No. 201.
PATENTS-AcTION AT LAW FOR INFRINGEMENT ANT'S PATEN1'. PRESUMPTION FROM DEFEND-
In an action at law, where the alleged infringing machine is made under a subsequent patent, defendant is entitled to an instruction that the issuance of such patent creates a prima facie presumption of a patentable difference from the machine of complainant's patent. Miller v. Manufacturing Co., 14 Sup. Ct. 310, 151 U. S. 208, and Boyd v. Tool Co., 15 Sup. Ct. 837, followed and applied.
In Error to the Circuit Court of the United States for the Northern District of California. This was an action at law by Thaddeus Hyatt against Ernest L. Ransome and others for infringempnt of a patent for improvements in compositions for floors, roofs, pavements, etc. In the circuit court there was a verdict and judgment for plaintiff in a nominal sum, and defendants bring error. Wheaton, Kalloch & Kierce, for plaintiffs in error. John L. Boone, for defendant in error. Before GILBERT, Circuit Judge, and KNOWLES and BELLIKGER, District Judges. GILBERT, Circuit Judge. The defendant in error was the plaintiff in an action at law brought to recover damages for the infringement of the Hyatt letters patent, No. 206,112, of date July 16, 187S, for an improvement in composition floors, roofs, pavements, etc. The specification of the patent refers to what are claimed to be "new and useful improvements in the use and application of hydraulic cements and concretes in combination with metal as a building material," etc., and describes the building material so referred to as hydraulic cement, "concrete," etc., and describes the combination therewith of metal bars or ties embedded therein, and having their surfaces roughened in some manner to prevent them from slipping horizontally in the material, and proceeds thus:
"To prevent slipping, these ties require also a roughened surface. This roughened or nonslipping surface may be made in many ways. For some purposes a mere sanded, tarred surface may possibly suffice, but I prefer to use metal specially rolled for the purpose, with bosses or raised portions formed upon the flat faces of the metaI."
The defendants manufactured building material in a manner similar to that described in the Hyatt patent, the only difference being that, instead of using metal with projections or bosses produced in the casting, they used a square rod, so twisted as to present the appearance of a screw. For the use of the twisted rod in such combination, the defendants had secured a patent of date September 16, 1884, which was read in evidence. The only assignment of error necessary to be considered is the refusal of the court to instruct the jury concerning the effect to be given to the fact that a patent had 150 issued to thp defendants.

In Corning v. Burden, 15 How. 265, the supreme court, after refer· ring to the presumption which attends the fact that, after an examination of the records of the patent office, a patent has been issued for the plaintiff's invention, said:
"It is not easy to perceive why the defendant who uses a patented machine should not have the benefit of a like presumption In his favor, arising from a like Investigation of the originality of his Invention, and the judgment ot the public officers that his machine is new, and not an infringement ot the patent previously granted to the plaintiff."
The case of Blanchard v. Putnam, 8 Wan. 420, overruled this hold· ing the court, and decided that evidence of the defendant's patent is not admissible. 'l'he decision in Blanchard v. Putnam was followed in the trial of this case, as also in that of Norton v. Can Co., 59 Fed. 137, where it was said:
"Abstractly, It would seem that, It the plaintiff's patent was prima tacle evidence of novelty (difference from things before it); a subsequent patent to the defendant, or for a device used by defendant, would be prima facie evidence of novelty (difference from all things before It, and hence from the plaintiff's device), and hence would be admissible in evidence on the Issue of infringement, and Its use would be innocent; and it was so held in Corning v. Burden, 15 How. 271. But this case was overruled In Blanchard v. Putnam, S Wall. 420.'"
The recent cases, however, of Miller v. Manufacturing Co., 151 U. S. 208, 14 Sup. Ct. 310, and Boyd v. Tool Co., 15 Sup. Ct. 837, cit· ing Pavement Co. v. Elizabeth, 4 Fish. Pat. Cas. 189, Fed. Cas. No. 312, expressly affirm the doctrine of Corning v. Burden, and hold that the issuance of the defendant's patent creates a prima facie presump· tion of a patentable difference from the prior patent of the plaintiff. The plaintiff in error was entitled, therefore, to an instruction which would permit the jury to consider the presumption that the law creates from the fact that a patent has issued in any case. The judgment will be reversed at the cost of the defendant in error, and remanded for a new trial.

PA.TENTS-DECISIONS BY OTHER COURTS.
Where a patent was. adjudged void by one circuit court after final hearing on the merits, and afterwards a demurrer to a bill for infringement was overruled by another circuit court, without an opinion, held, that the latter decision was not entitled to the same weight as the former, because the grounds of it were not apparent, and because a decision sustaining 11 patent Is not entitled to the same consideration as one declaring the patent Invalid. There is no Invention In attaching to each end of a hay rake (of the class usually drawn by two horses hitched to the ends respectively) a pole ex· tending forward, upward, and outward, to which the horse may be attached by a breast strap for the purpose of backing the rake from under Its load.
SAME-WHAT CONSTITUTES INVENTION.
