closure of the patent is not sufficiently complete with reference to the composition of the water soluble filler, but it does not seem to me that the patentee was bound to give a formula specifically describing the relative quantities of glue and dextrine, because it appears from the testimony that in very damp places it may be better to use dextrine alone, and by the same process of reasoning it would appear that it might be better to vary the proportions of glue and dextrine in other places, and these are matters which one skilled in the art could well determine, and it is not necessary in the patent to describe all the possible modes of application in order to obtain the best results. Minerals Separation, Ltd., v. Hyde, 37 S. Ct. 82, 242 U. S. 261, 61 L. Ed. 286. It makes no difference that the plaintiff may have found a paste suitable for his purposes which he uses, containing glue and dextrine with other elements, manufactured by a maker of glues and pastes, more suitable for large commercial production and cheaper than he could manufacture it, because the only question is whether the paste described in the patent will make a horn answering the definition of the claims. The testimony has answered that question in the affirmative, because I am convinced that Exhibit 14 was made in 1922, of the materials described in the patent, and is still rigid, and this patent should not be declared invalid for indefiniteness, or for insufficiency of disclosure.

[5] The defendant contends that there was an abandonmet by the plaintiff and the duty rests upon the defendant to prove such abandonment beyond a reasonable doubt. Kellogg Switchboard & S. Co. v. International T. Mfg. Co. (C. C.) 158 F. 104. This the defendant has utterly failed to prove, because the evidence shows that the plaintiff, through Mr. Foote, was trying to dispose of the crystal radio sets during 1923, and started to manufacture horns in quantities as soon as he received a large order. The defendant also failed to allege abandonment as a defense, as required by statute. Under section 4920 of the Revised Statutes (Comp. St. § 9466), the defendant had the right to plead the general issue, and, having given notice in writing to the plaintiff or his attorney 30 days before, may prove on the trial five enumerated defenses, the fifth of which is as follows: "That it had been in public use or on sale in this country for more than two years before his application for a patent, or had been abandoned to the public." [6] The notice required by the statute must be given by the defendant. Western Electric Co. v. Sperry Electric Co., 58 F. 186, 192, 7 C. C. A. 164; Warren Featherbone Co. v. Warner Bros. Co. (C. C.) 92 F. 990, 991. No such notice was given by the defendant. The defendant has not rebutted the presumption of validity of the patent in suit, and the weight of the presumption of priority and novelty which arises from the granting of the patent has been greatly increased by the concession of priority by Pollock & Horn to Abrahams in their settlement of the partially litigated interference declared by the Patent Office. Inasmuch as I am not laboring under any doubt, it seems unnecessary to enter into any extended consideration of the question of the commercial success of the patent. [7] The patent is valid, and there remains for further consideration only the question of infringement. Claim 1 of the patent in suit reads upon the defendant's structure, Plaintiff's Exhibit 2. The horn is made of fleece-lined material impregnated with a water soluble paste and baked. This claim is clearly infringed. The infringement of claim 2 depends upon whether the defendant's structure was impregnated with a hardened filler of glue and dextrine and having a surface finishing coating of a water paste. The paste used by the defendant, which was sold to it by Mr. Nach, contains glue and dextrine together with other ingredients. Mr. Wilson testified that he had sold quite a few horns on which additional paste was rubbed after the horns were baked. "Paint" is defined in Funk & Wagnall's New Standard Dictionary, as follows: "A solid color or pigment either dry or mixed with a vehicle, as oil or water, intended to form a surface coating as distinguished from a dye or stain." This definition is satisfied by a paste dissolved in water. Claim 2 of the patent provides, in part, "and having a surface finishing coating of a water paint." The purpose is to fill in the ribs and make a smooth exterior surface, 10 F.(2d) 843 2. Patents 91(3)-Patentee must establish claim to use antedating a prior use, by evidence of at least equal quality to that establishing prior use. and Mr. Wilson testified under cross-exami- invalid for lack of invention and anticipation, nation that he used this "as a filler" and "to but. if valid, not infringed. fill up grooves and holes in the horn." According to his testimony, he did sell quite a few horns on which such filler had been used. The infringement of claim 2 is clear, because plaintiff is entitled to be protected against further infringement even though the defendant claims to have discontinued that process, or that he found the addition of the water paint coating to be unsatisfactory. Defendant contends that on the authority of Brookfield v. Novelty Glass Mfg. Co., 170 F. 960, 96 C. C. A. 127, plaintiff is not entitled to an accounting. I do not think the decision in that case goes that far, but it seems to me that the plaintiff is entitled to an accounting, in addition to the profits which the defendant has realized, to determine the damages which the plaintiff himself has suffered by reason of the appropriation by the defendant of the plaintiff's rights under said patent. The allegations of the plaintiff's bill of complaint are not sufficient to warrant any recovery by the plaintiff of any damages suffered by his licensees, and further plaintiff does not pray for the recovery of any damages suffered by the licensees, but only the gains and profits of the defendant, and damages suffered by the plaintiff. [8] This, however, does not prevent the plaintiff from recovering the gains and profits of the defendant and damages suffered by the plaintiff, because it does not appear that any one has any interest, legal or equitable, by assignment or otherwise, in the patent sued on, or that the licensees mentioned are other than licensees at sufferahce.

ALFRED HALE RUBBER CO. v. MORSE & [1] The patent in suit is for the process of BURT CO. et al. attaching rubber soles to boots and shoes. (District Court, E. D. New York. February 5, The invention is said by the patentee in his 1926.) 1. Patents 328-1,479,497, for method of applying rubber soles and heels to shoes, held invalid for lack of invention and anticipation, but, if valid, not infringed. Cutler patent, No. 1,479,497, for method of applying rubber soles and heels to shoes, held specification to primarily consist in his "method of applying and securing the outer rubber or yielding sole or combined sole and heel to the shoe, independently of stitching the same, and in a manner to conceal, protect, and cover the stitching, if any, utilized in the construction of the shoe to which the ber unified into a single outsole, which conelastic outsole is applied." In carrying out his invention, the patentee says in his specification that he makes the shoe-either welt or McKay-in the usual manner, but that he secures, during the process of manufacture, "a thin rubber layer or intermediate sole to the shoe insole or to the attached welt. This may be by the usual welt stitching or McKay stitching. Preferably also I form this thin rubber sole of unvulcanized rubber, or a suitable rubber compound. I then prepare the main outer sole, also of yielding material, such as unvulcanized rubber or vulcanizable rubber compound of suitable size, thickness, and shape to complete the outsole of the shoe. I then coat the contacting surfaces or one of the surfaces and apply the outer sole to the previously attached rubber sole, preferably a thin strip or intermediate sole. These contacting surfaces are coated with a suitable solvent, which will act on the rubber itself to partially dissolve the same and permit the two soles by slight pressure and in a short space of time to become thoroughly and substantially integrally united." The patentee also says, in his specification, "that, where unvulcanized rubber is employed as at the outer sole and preferably also as the intermediate sole, a coating of benzol or the like will sufficiently dissolve the contacting and coacting faces of the two soles as to practically and solidly unify the rubber in both. The patent in suit is not limited to crepe rubber, but the midsole is described as "preferably" made of "unvulcanized rubber" or a suitable rubber compound, and the main or outer sole the patentee says may be "unvulcanized rubber" or "vulcanizable rubber compound." A rubber compound is a mechanical mixture of crude rubber, with other materials such as sulphur or pigments. This is quite different from crepe rubber, and a vulcanizable rubber compound is a compounded rubber in condition to be vulcanized, and this surely does not describe crepe rubber. Crepe rubber is mentioned but once in the patent, and that is in the specification where it is said, "The outsole, also of suitable rubber, preferably Colombo or other raw, unvulcanized rubber such as crepe, or latex. sists in providing two solelike layers, each of less thickness than that of the combined outsole, first applying one layer to the footwear and securing the same thereto by mechanical fastenings, then partially dissolving either or both of the contacting surfaces of the layers to be united, and then applying and holding the outer layer to the surface of the mechanically attached layer, until the partially dissolved surfaces become unified, whereby a complete solidified outersole of unvulcanized rubber is produced, having the mechanical attachments concealed therein." The shoe made and sold by the defendant Morse & Burt Company (Plaintiff's Exhibit 1) is stipulated to have been made as follows: "By first mechanically fastening a layer of 'crepe' rubber to the shoe, then coating the outer surface of said layer with benzol and the surface of another layer with benzol, then placing the two coated surfaces together, and holding them in position until the two layers adhered to each other." The rubber used by the defendant in its shoe in evidence is unvulcanized rubber, and benzol is a solvent, therefore, if the patent in suit is valid, no further consideration will be required of the question of infringement. The defendant in its brief relies on the defense of invalidity. The defendant offered in evidence the following patents of the prior art: British patent No. 1987, A. D. 1858, issued to Warne, for improvements in the construction of elastic pavements, etc., discloses that the use of a solvent to make two pieces of unvulcanized rubber adhere together is old. United States patent No. 34,682, issued to Godfrey, for improvement in india rubber boots and shoes, dated March 18, 1862, discloses double india rubber soles, each vulcanized, which are so formed that they will adhere to each other when cement is applied without being held pressed together. United States patent No. 616,470, issued to Kennedy, for rubber soled leather shoe, dated December 27, 1898, discloses a leather upper provided with the usual insole. Secured to the upper by mechanical means is a layer formed of leather, which extends out beyond the edge of the upper, a middle sole formed of textile material impregnated with rubber, which is of the same size and The patent has but one claim, which reads shape as the said layer of leather, and secured as follows: "The improved process of attaching to footwear two layers of unvulcanized rub thereto by mechanical means, and may also be secured to the upper by mechanical means, but such fastenings are independent of the 10 F.(2d) 843 tions. fastenings to said layer and an outer sole and ordinarily determined by the working condiheel which are vulcanized to the outer surface of the middle sole without any mechanical fastenings. United States patent No. 790,558, issued to Butterfield, for composite boot or shoe, dated May 23, 1905, discloses a layer of leather called the middle sole, and a layer of vulcanized rubber called the tread sole. Butterfield is doing in a slightly different way just what Kennedy was doing. United States patent No. 1,306,996, issued to Brown, for shoe, dated June 17, 1919, discloses a shoe bottom made of more than one layer of material, the insole being mechanically secured, the middle sole being in part mechanically secured, the outside sole and heel put in place, and the shoe is vulcanized, thus having an outer sole which is not secured by any mechanical fastenings. The patentee says: "My invention relates to a new and improved shoe of a character which can be manufactured by the methods commonly employed in a rubber shoe factory, as distinguished from methods commonly employed in a leather boot and shoe factory." The defendant also offered British patent No. 200,383, issued to Greengate and Irwell Rubber Company, Limited, and Walter Hubbard, effective date July 12, 1923. This patent is not prior art, and was offered by defendant "to show people all over the world were doing the same thing at the same time;" the application date being July 22, 1922. From these patents and the evidence of the experts we find that vulcanization was invented by Goodyear in 1844, and has been almost universally adopted because it increases the strength and elasticity of the rubber and also increases its resistance to heat over a wide range of temperatures; that from the beginning of the use of rubber it has been known that rubber which is clean and has a "tacky" surface can be joined to another piece of rubber in the same condition by simply pressing them together; that it was old in the art and standard practice, if the surface of two pieces have become dry, to coat the two surfaces with benzol or some other solvent, and then, after a pause to permit the surfaces to become tacky, to press the two surfaces together. It was also well-known and standard practice, where rubber has lost its original tacky surface condition and such tackiness cannot be restored by cleaning with a solvent, to resort to a rubber cement, and cement was also used with vulcanized rubber. Rubber cement is a rubber solvent and raw rubber, and the amount of solvent is The patentee in the patent in suit succeeded, in the Patent Office, in distinguishing his invention over the references there cited, and now contends that it is distinguished over the said references because they apply to vulcanized rubber, while the process of the patent in suit is limited to unvulcanized rubber. Without discussing that question at the moment, we are met on this trial with evidence, which was never before the Patent Office, of several alleged prior uses. The first alleged prior use is the Hoskins shoes. These shoes were made in 1917, long prior to Cutler's invention, in imitation of English rubber soled shoes, and, as appears by one of the shoes in evidence (Defendant's Exhibit 1), no stitches nor mechanical fastenings of the sole were visible, but the sole was vulcanized. Then came the so-called Addison Hanan shoes. None of the shoes alleged to have been made for Mr. Addison Hanan, about the same time as the Hoskins shoes, were produced, and, while I do not question the veracity of any of the witnesses, I am clearly of the opinion that the evidence of such alleged prior use, both in the case of the Hoskins shoes and the Addison Hanan shoes, is not sufficiently strong to comply with the requirements which have been laid down by the courts in like cases. The Barbed Wire Patent, 143 U. S. 275, 12 S. Ct. 443, 450, 36 L. Ed. 154; Deering v. Winona Harvester Works, 155 U. S. 286, 15 S. Ct. 118, 39 L. Ed. 153. In 1921 the English introduced the use of crepe rubber for soles for sport shoes; the idea having originated with the young men on the rubber plantations at Colombo, and been communicated by them to their firms, who began to introduce them on the English market. Mr. Wilson, importer of crude rubber, saw crepe rubber soled shoes in London in September, 1921, and received a number of pairs as samples from London in the fall of 1921, which he in turn distributed among his friends whom he thought might be interested. Mr. Cutler, the patentee of the patent in suit, was shown an English shoe with a crepe rubber sole, on May 1, 1922. The English, in making the crepe rubber soled shoes, followed common English practice, and cemented the soles, which proved satisfactory because of the careful way in which the English cement rubber to leather. This appears to be true, notwithstanding the statement in British patent No. 200,383, supra, which speaks of these rubber soles cemented directly to the leather as "inclined" to separate from the leather. This brings us to the crepe rubber soled shoes made by Hanan & Son. About the same time in the spring of 1922 that Mr. Cutler saw the crepe soled English shoe, Mr. H. W. Hanan, of the firm of Hanan & Son, was in London, and evidently saw crepe rubber soled shoes and purchased and sent to Brooklyn some crepe rubber in sheets, which was received in Brooklyn about the middle of May, 1922; the invoice being dated May 3, 1922. Apparently he must have sent some cable or letter of instructions, but the same cannot be found. Orders were then given (of which Exhibits A and C are samples), and under direction of Mr. Brunell, the superintendent of the Hanan factory, manufacture began. He first made a sample with a single layer of rubber at the fore part and two layers at the heel, one of which was a wedge to form a spring heel, and tried to sew the sole thus made up entirely around its edges. In doing this, he met with difficulty because, if the sewing machine was properly set to sew the single thickness, the thread would draw down into and cut the rubber at the double thickness. He then made the shoes with the heel wedge sewed to the equivalent of a welt at the heel and a single full sole layer "sewed aloft" to the welt at the fore part of the shoe, and such single layer brought down over the heel wedge and cemented to it, no stitches passing through the outer sole at the heel portion, as illustrated in the shoes, Exhibits T, B, and E. The records of Hanan & Son are well kept, except that the particular method of construction is not fully shown on the order, but the lots of shoes manufactured are given a lot number, and the progress of each lot through the factory is fully shown. To show the exact construction, however, it is necessary to obtain one of the shoes, and then by its lot number its date of manufacture can be readily ascertained, and that is what was done in this instance, as there were obtained from one of the retail stores Exhibits B and T, which are of the same lot number, 87926 L, and there came back to them because of a loose lining, Exhibit E, which was of lot No. 87911 L. On May 17, 1922, the assistant general manager of Hanan & Son's retail stores wrote out orders to make a quantity of shoes for each of a number of stores; Exhibit A being for two lots, No. 87925 L and No. 87926 L, seven pairs each, and Exhibit C for two lots, No. 87909 L and No. 87911 L, for seven pairs each, soles made of "new H. W. Hanan rubber." The making of these shoes was shown, not only by oral testimony, but by the written records of Hanan & Son and the shoes, Exhibits B and T. These shoes were cut June 1, 1922, leveled June 29, 1922, at which time the sole was completed, certain finishing was done, and the shoes completed July 12, 1922, and shipped July 18, 1922. The sole of the shoe, Exhibit E, was leveled July 20, 1922. The soles of these shoes were made of unvulcanized rubber of the kind known as crepe rubber, there was the wedge at the heel portion, which was sewed to the equivalent of a welt, and an outer sole which was sewed to the fore part of the shoe and cemented to the wedge at the heel portion, whereby these portions became unified. Although the two layers of rubber in Exhibits B, E, and T appear only at the heel, the inventor's thought, if there was any invention, is fully exemplified, and no limit can be set to the carrying forward of the wedge, because, if desired, it can be carried to the toe. These shoes evidently gave satisfaction, as about 1,000 pairs were made. In the face of these shoes, made as they were before the application of the patentee in the patent in suit was filed, Exhibits B and T having been some time even before the date to which the patentee has attempted to carry back his invention, the shoes even having been shipped on that day, if it be held that there is any invention by the patentee in the patent in suit, it must consist simply in carrying forward the inner layer shown at the heel portion of said Exhibits B and T, and this at most would seem to me to be only the act of a skilled workman, desirous of improving the looks of the shoe. Smith v. Nichols, 21 Wall. (88 U. S.) 112, 22 L. Ed. 566. Some time after Hanan & Son began to make shoes like Defendant's Exhibits B and E, the construction was somewhat changed by their superintendent, as he said, to "make a better looking shoe." This construction was described as having one layer of crepe rubber sewed to the welt entirely around the shoe, then two wedges of crepe rubber cemented to this first or midsole, at the heel, and then the outer sole cemented to this midsole and to the heel wedges, the outer sole |
