Opinion

DODGE, Circuit Judge.

The plaintiff in this bill, filed July 20, 1916, owns United States patent No. 1,177,833, issued April 4, 1916, to John G. Tufford, assignor to the plaintiff company, for mold for making rubber heels. As the case was presented at the hearing, the plaintiff contended that only one of the twelve claims of the patent had been infringed by the defendant, viz. claim 11, which is as follows:

“11. A mold for forming heel lifts, including assembled parts, one of which is provided with a molding chamber having the general outlines of a heel lift, one wall of the molding chamber being concave, and the opposed wall of said chamber having a convex surface coacting with said concave wall, one of said walls being- provided with washer supporting devices.”

September 18, 1916, in compliance with an order of court, the plaintiff specified, as the structure which it would “contend at the hearing constitutes an infringement,” the mold structure illustrated in certain annexed drawings, marked “Plaintiff’s Exhibit 1, Sheets 1 and 2.”

December 4, 1916, in answer to interrogatories filed by the plaintiff, the defendant produced a three-part rubber heel mold, marked for identification “Defendant’s Mold,” and admitted that said mold, or others identical therewith, were used by it since April 4, 1916, and prior to the filing of the bill.

Assuming the validity of the above-quoted claim in suit, according to its broad terms, there seems to me no doubt that molds like the one marked “Defendant’s Mold” which are, for all essential purposes, such molds as the above drawings marked “Plaintiffs Exhibit 1” show are within the terms of the claim, so that their use by the defendant would have to be regarded as an infringing use.

A question of more difficulty, however, arises as to the validity of the claim in issue, which is denied by the defendant.

[64]*64In the plaintiff’s patent a mold said to embody the patented invention is described, with references to drawings which show both a “mold unit” and an “assembled multiple or gang mold.” The mold so shown and described has certain features to which no reference is made in the above claim in suit, although they appear as elements of other claims of the patent not here in suit. - The mold shown and described is, a three-part mold, consisting of a base plate, an intermediate plate, and a top plate. Claim 11 purports to cover any mold for forming heel lifts, without regard to the number of parts composing it, in one part whereof there is a molding chamber having the general outline of a heel lift, one wall of which chamber is concave, the opposed wall convex and coacting with the concave wall, and one of the two walls provided with washer supporting devices.

The first inquiry is as to the substantial difference between a mold having the aboverdaimed features ■ and heel lift molds previously known and used.

Heel lift molds, for forming rubber heels, whose molding chamber had the general outline of a heel lift, were and long had been familiar. In most of them, one or both the opposed walls of the molding chamber were flat. In some, one of the walls, being that intended to form the top of the heel lift, had a projection or convexity, while the opposed wall, intended to form the bottom of the heel lift, was flat. From such molds, molds satisfying the requirements of the claim in suit differ only in having the opposed wall of the molding chamber and intended to form the bottom of the heel lift concave, instead of flat, and thus coact, if so shaped, with the convexity opposed to it. As to the washer-supporting devices wherewith one wall of the chamber is to be provided, according to the claim in suit, they were familiar in the prior molds referred to and can be regarded as a novelty, if at all, -only in combination with the other features of the claim.

In molds for forming articles of molded rubber other than heel lifts, the idea of ■ having one wall of the molding chamber convex, so as to coact with a concave opposing wall, was old; as is shown by Defendant’s Exhibits I, K, M, and O, and by the evidence relating to those exhibits. There would be difficulty, in any event, in discovering anything amounting to invention in merely making one wall of a heel lift molding chamber, having a convex wall opposed to it, concave instead of flat, as in the prior heel lift molds above referred to; but whether or not to do this could be regarded as patentably new, if Tufford had been the first to do it, need not be. determined, because the evidence satisfies me that it had been done long before the patent in suit issued, in molds like “Defendant’s Exhibit Nerger Mold,” made and used by Morgan & Wright Company, at their factory in Chicago, between 1897 and 1902.

The evidence regarding such molds and their prior use was taken under an order made herein on July 24, 1917, upon a motion by the defendant to reopen the case for the introduction of newly discovered evidence, filed July 3, 1917, after completion of the original hearing on June 14, 1917. By stipulation between the parties, the [65]*65evidence consists of the defendant’s affidavits in support of said motion, the plaintiff’s answering affidavits, and defendant’s reply affidavits. The Nerger mold, produced as an exhibit, answers, so far as I can see, each and every requirement of the plaintiff’s claim 11 here in suit. It is a single cavity mold, or mold unit. With it, or molds like it, were made over 2,000 heels, upon Nergef’s order, of merchantable quality so far as appears. There was no concealment regarding their manufacture, and it was known to Nerger himself and to a number of employes of the Morgan & Wright Company, who have testified about it. Specimens of them are exhibits in the case. The heels produced were made under United States patent to Nerger, No. 661,129, issued November 6, 1500, for an improvement in rubber heel lifts. There is evidence that the mold produced many imperfect heels, and that the cost of the heels produced was too great for profit. But this was partly because of the fact that it is more economical to use multiple molds than single unit molds — a fact which seems to me immaterial upon the question here involved, because there can be no invention in combining single into multiple molds. I see no reason to doubt that the Nerger mold, properly adjusted and handled, is entirely capable of producing satisfactory heels. In 1916 Nerger sold his patent to the plaintiff in this case, together with six of the molds which had been used by Morgan & Wright in the manufacture above described. Although Nerger does not appear to have further continued the use of his mold in making heels, I am unable to hold that, as the plaintiff contends, it was merely an unsuccessful and abandoned experiment. Upon the evidence regarding it, I must regard his mold as an anticipation of the structure covered by the plaintiff’s claim in suit sufficient to prevent any conclusion that the claim covers anything involving invention or patentably new. '¡'lie mold described in the patent has various features to which the claim in suit makes no reference, as further staled below; but these, as will also appear, are not found in the defendant’s mold.

The plaintiff's evidence sufficiently shows that concavo-convex,' heel lifts, such as may be made by using the mold described in the patent in the manner therein set forth, have had great commercial success and possess qualities rendering them superior to heel lifts not shaped as the patented mold shapes them, and made according to the method which the patent describes.
