23 F.2d 384 | 1st Cir. | 1928
In tbis suit infringement of letters patent of tbe United States No. 1,071,027, issued August 26, 1913, to Eredriek A. Bruckman, for an automatic pastry-making machine, is alleged. In American Cone & Wafer Company v. Denaro, 297 F. 913, tbis court adjudged the patent valid and infringed. Denaro has since made certain changes in the machine there held to infringe. Tbe validity of tbe Bruckman patent having been determined by this court, tbe only question to be decided by tbe District Court was whether bis alleged changed machine infringes. It has held that it does, and from this decree an appeal has been taken.
Tbe appellant has filed a petition for leave to file a supplemental bill in tbe nature of a bill of review and a memorandum in support of tbe petition. Tbis petition is
In the present ease it is claimed that applications for patents to Lanier, No. 1,257,-497, to Bohlig, No. 1,047,122, and to Wessel, No. 1,148,642, were filed in the Patent Office prior to Bruekman’s application, but that patents were not issued, except to Bohlig, until after the patent to Bruckman was issued, and that, under the law as it was understood in this circuit when the decision was rendered in American Cone & Wafer Co. v. Denaro, supra, and in the Eighth Circuit (Roberts Cone Mfg. Co. v. Bruckman, 266 F. 986), where the Bruckman patent had been under consideration, only patents which had been issued at a date prior to that of the patent in suit could be considered in determining whether the inventor of the patent claimed to be infringed was the first inventor or not.
The McLaren Consolidated Cone Corporation, Ine., has succeeded to all the rights of the original plaintiffs in the suit of American Cone & Wafer Co. v. Denaro, supra, and has been substituted as plaintiff.
The bill alleges that the defendant still continues to manufacture and use machines which come within the scope of and infringe the Bruckman patent; that, while some parts are substantially identical with Bruckman, others differ only in details of construction and operation.
Bruekman’s patent relates to the manufacture of ice cream cones. In the opinion of this court in American Cone & Wafer Co. v. Denaro, supra, it was said: “While Bruckman had made use of well-known elements, all of them old, yet by a new combination and sequence of operations, which he introduced in his step by step method, and the ingenious and novel method which he contributed for extracting the cone from the molds automatically, thus doing away with the unsanitary conditions caused by extracting the cones by hand, he produced a new and beneficial result never attained before and largely cheapened the cost of production.”
Accord was expressed by it with the following language in the opinion of the Circuit Court of Appeals in the Eighth Circuit in Roberts Cone Mfg. Co. v. Bruckman, 266 P. 986: “Bruckman has created a machine which automatically takes a semi-fluid, adhesive batter from a tank, carries it through all intermediate stages of formation, baking, trimming, and conveyance, and finally deposits it as a finished, fragile, commercially perfect crust cone on a table ready for packing into cartons. No such result hp,d ever been accomplished before; it was a useful result, and accomplished in a highly satisfactory and sanitary manner. This entitles his machine to be considered a pioneer in the field of automatic production of sanitary batter cones.” It was held by this court that the method of extracting the cone from the mold was Bruekman’s valuable contribution to the art, and produced a result never before accomplished, and that the claims which covered it, read in the light east upon them by the drawings and specifications, should be given a liberal construction.
If the patents which had been applied for prior to Bruekman’s application had been considered, the result reached would not have been different from that arrived at. Bohlig was prior to Bruckman, both in his application and his patent. Its molds are of solid type, and after the cones are cooked they are ejected by push-pin devices. This patent was clearly distinguishable from Bruckman. Lanier, 1,063,981, was placed in interference with Bruckman, but not upon the extraction claims. In this the cones axe removed by hand. There was nothing in the application to apprize one of the advantage of holding the core within the mold to assist in stripping the cone from the mold. Lanier, 1,257,407, was applied for in December, 1908. The patent in suit was applied for May 11, 1910. They were therefore copending in the Patent Office more than three years. Lanier in this operates on an entirely different principle from Bruckman in the extraction of the cones. In it the cores are removed from the sockets or molds, with the baked cones adhering to them by reason of slight notches upon the surface of the cores, and then the cores are caused to rotate to detach them from the baked cones. The fact that it was copending so long with Bruekman in the Patent Office, and no interference declared upon the extracting process, creates a strong presumption that Bruckman in this process had patentable novelty. See Farmers’, etc., v. Beaver, etc. (C. C. A.) 236 F. 731. In Wessel, 1,148,642, the applica
If, in the light of Alexander Millburn Co. v. Davis-Bournonville Co., supra, these applications had been considered, they would not have affected the claim of Bruekman to be the first inventor of the extraction method, which he showed and which the court found entitled him to be classed as a pioneer. The petition to file a supplemental bill in the nature of a bill' of review is therefore denied.
The alleged infringing machine of Denaro was in operation in the city of Cambridge; and the learned District Judge, in order to avail himself of a close inspection of this machine - in operation, adjourned the hearing to the factory where it was being operated, and some of the testimony was taken there.
Although counsel have in great detail pointed out other important particulars in which it is claimed infringement was proven, we content ourselves with considering again the invention which Bruekman made in the extraction of the baked cone from the molds without being touched hy the hand. .The infringing machine, as did the first machine of Denaro held by this court to infringe, retains the core within the molds while they are being separated. Although in the second machine it is claimed that the slight raising of the core within the mold is simultaneous with the cracking open of the mold, yet during the whole of the remainder of the opening of the mold, until the baked cone drops from it, the core remains suspended within it, and assists, as does the core in Bruekman, in stripping the cone from the mold. It is entirely immaterial whether the core is raised simultaneously with the partial opening of the mold, or whether this raising precedes that opening as in Bruekman. The purpose for which this is done is the same in both, namely, to free the core from the cone which adheres to it, and then the core is left suspended within the mold, to assist in stripping the cone from its sides as it is opened. Not only is the same result accomplished in both, but the means used are practically identical.
Error is assigned because the District Couxt declined to receive in evidence- certain depositions bearing upon the price of ice cream cones, both before and after Bxnxekman’s machine was put upon the max’ket. As the patent had been held by this court to be valid, these depositions were correctly excluded.
The decree of the District Court is affirmed, with costs to the appellee.
