These are bills in equity for the alleged infringement of letters patent No. 345,965, issued to complainant July 20, 1886, for improvements in hats and caps. The defendants demur to both bills. The demurrers are the same in each case, with a single exception, which will be separately considered.
The first four grounds of demurrer assigned are that the patent is void on its face for want of patentable novelty, and because the claim does not comprise a combination. That this objection may properly be raised by demurrer is well settled. Brown v. Piper, 91 U. S. 43; Blessing v. Copper Works, 34 Fed. Rep. 753; Fougeres v. Murbarger, 44 Fed. Rep. 292; Bottle Seal Co. v. De La Vergne Bottle & Seal Co., 47 Fed. Rep. 61.
The claim of the patent in suit is as follows:
“In a cap or hat having a flexible tip, the body or skeleton of the side crown formed of wire cloth, the ends of which axe connected by angular seams, as set forth.”
The defendants urge that the specification and claim show the patent to be for a mere substitution of one well-known material for another, and a connection such as would be made by any skilled operator. The question of patentable novelty, when raised by demurrer, must be determined in favor of the patent, unless the court can see from an examination of the patent itself, and a consideration of those facts alone of which the court will take judicial notice, that the patent does not describe such an advance in the art to which it relates as to constitute invention. Bottle Seal Co. v. De La Vergne Bottle &. Seal Co., supra; Engraving Co. v. Hoke, 30 *827Fed. Rep. 444; Dick v. Supply Co., 25 Fed. Rep. 105. In the present ease, the patentee does not claim merely the substitution of one material for another. He admits that hair cloth has been used for the crown lining in hats and caps. But he says, further:
“The essential feature of my device, therefore, fa not only the ns© of wire cloth, but also the ©©cellar cutting of the wire cloth, to have its -wires on a diagonal line to the edges of tli© cloth, as else the desired elastic ©span sion and contraction of the side crown for stretching the tip will not be obtained, and that otherwise the shape of such wire-cloth body cannot be made conical.”
The patentee daimfí tía at by the substitution of the new material, so cut that the woven wires are on diagonal lines relative to the band and tip, and are connected by angular seams, certain new and useful results are produced He further claims that these results are produced, by the combination of coactitig and co-operating dements.
An examination of the patent, and 0, consideration of the alleged invention, seem to show that the presumption of patentable novelty arising from the grant of the patent has not been rebutted, The patentee Is entitled to the benefit of any doubt which, may exist in the mind of the court, Whether, in view of the state of the art, there was any invention, whether the alleged invention consists merely in. the substitution of one material for another, and whether, as is strenuously maintained by complainant, its practical utility can be shown by the fact that it has displaced other inodes of manufacture, are questions of fact which cannot be disposed of upon, this healing. The first, second, third, fourth, and sixth grounds of demurrer are overruled.
The fifth ground of demurrer assigned is that the complaint does not aver that the invention had not been patented or described in any printed publication before the date of said invention. The ©mission of this averment is a defect in form which is demurrable. Coop v. Institute, 47 Fed. Rep. 899; Overman Wheel Co. v. Elliott Hickory Cycle Co., 49 Fed. Rep. 859.
The seventh ground, of demurrer assigned in the ease of Goebel v. American 'Railway ¡Supply Co. et ai is that the prayer for process of subpoena does nor contain the names of all the defendants named in the introductory part of the bill. This omission is in violation of role 28, U. S. Eq. Prac., and is a fatal defect. City of Carisbad v. Tibbetts, 51 Fed. Rep. 852.
The fifth ground of demurrer in each case, and the seventh ground ©f demurrer in Goebel v. American Railway Supply Co., are sustained, with leave to amend in 35 days in both cases, upon payment of costs in Goebel v. American Railway Supply Co.
