161 F. 343 | 7th Cir. | 1908
(after stating the facts as above). The patent in suit, No. 740,982, involves no question of advance in method or means of lighting trains of cars by electricity, with the revolution of the car wheels utilized for generating the current, beyond improvement in the means for suspension and operation of the dynamo outside of the truck-frame of the car Both utility and commercial value of the device are facts in this record, but the narrow scope of the claims alleged to be infringed is likewise well established, if their patentability can be upheld under the evidence. The prior state of the art appears from uncontroverted testimony and exhibits, and no review in detail is needful for present consideration. We deem it sufficient to mention these facts as thus established in this record: The lighting of cars by electricity was well known, and various methods were in general use on railroad trains. An early means was storage batteries, carried on the car and charged for each trip; and later a dynamo and engine were employed for the purpose, carried on the car or train, as exemplified .in Arnold’s patent of 1887, No. 866,292. Then came the system of using dynamos “driven from the car-axles,” as referred to in the patent
The decree upholds the validity of claims 1 and 2 of the patent, with limited scope, so that all the devices made by the defendant, except one of earlier construction, “applied by it to café car No. 7,594 of the Pennsylvania Company,” for which relief was granted, were pronounced free from infringement; while claim 3 was limited thereby “to the specific form of cradle irons shown in the drawings,” and the bill dismissed as to that claim for noninfringement. In the appeal by the complainant broader construction is sought of all these claims, and extension of relief thereupon against all of the defendant’s strüctures in evidence, with the limitations placed upon the alleged invention as the sole question for review. The cross-appeal of the defendant, however, raises the questions of validity, as well as scope of these claims; and the patentability of the device is challenged, under the answer and evidence, as neither an original conception by the patentee, nor otherwise involving invention.
Careful examination of the record and briefs has confirmed the impressions we brought from the oral argument that the complainant’s contentions as to the scope of invention, for more liberal interpretation of the claims, to reach other devices made by the defendant than the one originally used and adjudged to be an infringement, are untenable, that error is not well assigned, for the interpretation applied by the trial court, in so far as the relief granted by the decree, was thereby limited, and that the complainant raises no well-founded objection to the decree under its appeal. In view of our conclusions upon the defense arising under the cross-appeal, the foregoing propositions'do not require specification, either of the rules of limitation thus applied to the claims, or the facts in evidence for their application.
The defendant seeks reversal of the decree, notwithstanding the seeming unsubstantial measure of relief granted in favor of the patentee, and the twofold defenses set up against the patent and claims in suit are pressed for consideration to that end on the cross-appeal. Both are issues of fact, fairly raised by the evidence, and neither is
The patent (No. 740,982) wras issued October 6, 1903, on Kennedy’s application, verified April 21, 1903, and filed June 5, 1903. Thus the prima facie case is thereby established of complete conception by the patentee as of the date of his application (Robinson on Patents, §§ 132, 372, 380, 1024; Walker on Patents, §§■ 69, 70, 510); and the right of the patentee is well recognized to carry the date hack to the actual inventive act, as against rival claimants. (1 Robinson on Patents, § 132.) When the defense of anticipation is set up, it is unquestionable that the defendant is charged, not only with the burden of proof upon that issue, but priority of conception and reduction to practice must be clearly made out, by well-authenticated evidence, to defeat the patent. That burden, howrever, has been completely satisfied by the proof introduced for prima facie support of the present defense, in so far as evidence of priority in reduction to practice can meet these requirements; and the question thus arises: Is not the burden of anticipating this undisputed fact of priority in making and using the device, thereupon transferred to the claimant under the patent ?
The established facts, at the stage of the case referred to, are substantially these: The patentee, Kennedy, and the witness Sherbondy (introduced for the defense) are rival claimants for priority in conception of the substantial features of the patent device. Both are engineers of recognized skill in electric equipment — Kennedy, as chief engineer of the complainant company, and Sherbondy, as chief electrician of the Pennsylvania Railroad — and each was engaged, in tluj course of duties, in devising improvements for the system of lighting cars by electricity. They were acquaintances, and in business relation for equipments in such line. Prior to 1903 Kennedy had obtained patents for several suspension devices — including one for so-called “outside suspension,” in No. 699,187, issued May 6, 1902, on application filed August -17, 1901 — and was soliciting, for his company, equipment of various railroads, including the Pennsylvania, with the outside suspension, which he hoped to improve, as none of his earlier devices were entirely satisfactory. Sherbondy (as we assume) was acquainted with these various patents, and with Kennedy’s quest, both
With the above-mentioned facts of complete anticipation in construction, and use — known to the patentee several months prior to his application for a patent — -settled by the evidence, we are of opinion that the presumption of invention by the patentee, which arises from the patent, application, and grant, is overcome, prima facie, by such anticipation in Sherbondy’s prima facie conception reduced to practice, so that the burden of proof is transferred to the patentee to establish priority in fact. Westinghouse Electric & Mfg. Co. v. Catskill Illuminating & Power Co., 121 Fed. 831, 834, 58 C. C. A. 167. This view of shifting the burden of proof in such event is upheld in well-considered opinions at the circuit (Webster Loom Co. v. Higgins, 15 Blatchf. 446, Fed. Cas. No. 17, 342; Thayer v. Hart, Jr. [C. C.] 20 Fed. 693; Westinghouse Elec. & Mfg. Co. v. Saranac Lake Elec. L. Co. [C. C.] 108 Fed. 221, 222; Westinghouse, etc., v. Mutual Life Ins. Co. [C. C.] 129 Fed. 213, 216), and stated in Walker on Patents, ’§ 510. In Clark Thread Co. v. Willimantic Linen Co., 140 U. S. 481, 492, 11 Sup. Ct. 846, 851, 35 L. Ed. 521, however, the opinion by Mr. Justice Bradley states the rule in like case, in qualified form, as requiring “the plaintiffs, in rebuttal, to show, if not with equal certainty, yet to the satisfaction of the court, that the invention” claimed in the patent preceded the date thus shown with certainty, in respect of a device which anticipated the patent dates. For the purposes of the presentíase we deem it immaterial which of the rules thus stated is applied to the evidence for determination of the issue, as neither side furnishes satisfactory and convincing proof, consistent with other testimony, of a well-defined perfection of the alleged invention at any period prior to December, 1901, within the rule as stated in the last-mentioned opinion — bearing in mind, as there remarked (page 489), that “a conception of the mind is not an invention until represented in some physical form.”
While it is true that drawings are introduced on behalf of the patentee, exhibiting the suspension means, with testimony which tends to fix their date, as stated in complainant’s brief, “somewhere between July and the last of October, 1901,” each exhibit rests on the recollection and credibility of witnesses for the alleged date, at best stated indefinitely; and the drawing, which is relied upon for complete representation of the device, shows erasures and changes, which are not
Without attempting to detail the extended testimony in reference to the various efforts to provide for locating the dynamo outside the truck of the car, the following circumstances are pointed out as uncontroverted and anterior to the Kennedy application, filed June 5, 1903, namely: (a) When Sherbondy completed his equipment of cars, in December, 1901, the only device for like location of the dynamo, which had been made or applied by Kennedy, was that described in his patent of 1902 (No. 699,18?) which was applied to Grand Trunk cars about June, 1901, and later was placed on a Santa Fé car, and reported satisfactory. (b) Assuming that he was then contemplating and working out an improved device, Kennedy had neither applied nor made one which embodied the simple adaptation of the present patent, before his attention was called to the device operating on Pennsylvania car No. 7,-WO. (c) Nor does it satisfactorily appear from the testimony that any portions of equipment, specially adapted for the device of this patent, were actually made by Kennedy or his company prior to 1902 — as the shop orders in evidence are equally referable to the earlier devices — while it does appear that Kennedy’s directions (January I, 1902), for Santa Fé cars to be “equipped with the outside suspension” (theretofore ordered by that company), were written after his examination of the Pennsylvania car. (d) Kennedy’s application for the patent (No. 699,187) of 1902 was filed August 17, 1901, and he was absent in Europe after that date until about October 8th. Pie testifies that upon his return he “took up the question of improving the outside suspension generally, and working out the details particularly.” (e) While Kennedy'testifies that Sherbondy’s device was made under Kennedy’s conception, as communicated when they met at Ft. Wayne, November 28 or 29, 1901, his statement of what was said is insufficient for such communication, namely: “I told him what I was doing, in a general way, in the design of a new outside suspension, which would overcome” objections to the earlier device. This is expressly denied by Sherbondy; but. aside from the dispute of fact, no clear communication appears of the single feature on which patentability must rest, simple as that element is when disclosed, (f) In Kennedy’s version of the conversation with Sherbondy, November 28th or 29th, in which it was understood that each was working out a method of outside suspension for practical use, no claim or suggestion
Under the state of facts thus appearing, we are of opinion that the patentee fails to establish such priority in conception over the Sherbondy device as must be required to uphold patentability, within either of the above-mentioned definitions of the rule to be applied. No circumstance in the case authorizes acceptance of the patentee’s testimony as outweighing that of Sherbondy upon such issue, while the witness Sherbondy appears to be disinterested in so far as concerns the present controversy, and his testimony is consistent with the undisputed facts. In no view of the record are we impressed with the sufficiency of the evidence to carry Kennedy’s alleged invention back.of 1902, so that the undeniable anticipation of that date by Sherbondy leaves the decree without support.
The decree of the Circuit Court is reversed accordingly, with direction to dismiss the bill for want of equity.
