Opinion

HAZED, District Judge.

We are here concerned with the alleged infringement by the defendant company of various letters patent relating to eyeglass 'mountings, issued to Deo F. Adt, as follows: Reissue letters patent No. 13,466, dated. September 17, 1912 (originally No. 1,019,115, dated March 5, 1912), patents Nos. 1,040,094 and 1,-040,096, both dated October 1, 1912, and patent No. 1,173,912, dated February 29, 1916. Infringement is asserted since the cancellation, February 26, 1916, by mutual consent of a license to manufacture and sell the eyeglasses in question; the defendant continuing to market eyeglasses with nose bearing pads pivoted and actuated towards each other and separated by a spring, and having means for spreading the glasses apart. Such eyeglasses are illustrated in defendant’s structures, Model G mounting and Model G Modified or Model G Intermediate mounting in evidence, which plaintiff claims are infringements of his patents in evidence, viz.: Model G of claims 2 and 28 of the reissue patent, claim 5 of patent No. 1,040,096, and claims 1 and 2 of patent No. 1,173,912, and Intermediate Model G, of claims 2, 28, 43, and 50 of the reissue patent, claims 5 and 18 of patent No. 1,040,096, and claim 12 of 1,040,094, in suit.

[1,2] The defense is want of novelty and invention in view of the prior state of the art. The patentee concededly was not the first to pro[278]*278vide eyeglasses with nose guards and finger pieces pivotally mounted on a table or support between the arch of the bridge and the abutting lenses; nor did he first interpose a wire spring and lever on the table or support between the bridge and connecting lenses for use in spreading apart the nose pads for gripping the nose. Such a device and arrangement of parts were first used by Jules Cottet (patent No. 560,895, dated May 26, 1896), and their practicability and usefulness are beyond question. Adt, however, claims that there were various objections to the Cottet mounting: First, the spring was exposed, and therefore dirt and dust were likely to collect on the coil surfaces; second, the parts were faultily arranged, causing the finger piece lever to wobble; and, third, to replace a broken spring the nose gripping unit had to be dismantled. To overcome such objection he claims to have made by stages patentable improvements eventuating in the fourth patent in suit as embodied in defendant’s Model G mounting, wherein the flat spring is readily detachable. Importance is attached in each patent to the specific details of construction, the character of the lever, screw head, spring, and assembling of parts, which finally, it is contended, overcame the objections tó prior mountings of the finger piece type.

It is necessary to familiarize oneself with the various modifications that were made, for at the outset it is questionable whether any involved invention. Two of such patents — the reissue (15 claims) including claims 2, 28, and'43, here in controversy, and No. 1,040,096 — were held invalid by the Circuit Court of Appeals for the First Circuit (Adt v. Bay State Optical Co., 226 Fed. 925, 141 C. C. A. 529), leaving for this court to pass upon claim 50 of the reissue, claims 5 and 18 of No. 1,040,096 (substantially similar to claims 26, 27, and 29, involved in the Bay State Case), and claim 12 of No. 1,040,094, said to cover defendant’s Model G Modified mounting, and the two claims of patent No. 1,173,912, bearing on the spring arrangement, as shown in Model Exhibit 9. The District Court and the Circuit Court of Appeals for the First Circuit decided substantially that the structural differences in the various patented mountings considered by them were simply modifications of a single species and substitutions of one for another, and did not involve invention. This decision practically determines the status of the subject-matter, and, unless the evidence now presented is essentially different and persuasive of an opposite conclusion, it should in the interest of uniformity of federal decisions be accepted and followed by this court. As letters patent and claims are in issue here that were not expressly passed upon in the former suit, they will be briefly taken up in connection with the prior art.

All, or nearly all, of the involved claims relate to exceedingly small differentiations in structural parts and the manner of assembling them. In dealing with the reissue patent it will suffice to set out claim 28 only, which is descriptive of the improvement:

“28. In an eyeglass mounting, the combination with a support having a seat on one side thereof, of a headed pivot projecting from the seat, a projection on the opposite side of the support aligned with the pivot, a nose guard turning on the pivot in engagement with the seat and head, and a coil spring for positioning the guard surrounding the projection on the opposite side of the support.”

[279]*279Claim 2 also describes a guard pivoted on one side of the support with a flat spiral spring below it. Claim 43 positions the spring beneath the support or bridge, and refers to a guard lever held in rigid bearings, while claim 50 broadly recites the combination with a support and pivoted guard lever of a coil spring in a flat spiral, its outer end acting against one of said parts, and its inner end extending beyond the circumference permitting it “to act against the other part.”

On comparing the structure of the reissue patent with the Cottet disclosure, it will be observed that the modifications are slight. The patentee appears to have worked assiduously in this art to evolve changes and modifications in prior mountings, as quite a number of patents, granted to him previously, but not in suit, especially Nos. 862,-368 and 872,211, would seem to prove. He seems to have believed that the coil spring in the Cottet structure mounted on top of the support would easily break and that the guard lever held down by- it would wobble, and therefore he designed to locate under the support another kind of spring to insure firmness. He extended the spring used by him outwardly from the center, looping it to contact with the upper part of the support under the screw head and then forming a convolution for the finger and nose piece — all in one, the other end of the spring being screwed down on the lens frame. In Cottet the spring was held down on the guard lever by the screw head, the upper end being anchored on the lens. Adt’s convolution of the spring, though unique to the uninformed, nevertheless comprised a mounting not essentially different from prior mountings in evidence, either as to form, location, or anchorage at their ends. He does not appear to have secured ready removability of the spring in the reissue patent as it was apparently necessary to remove the guard lever in removing the spring; while in the Cottet mounting, as witnesses testified, the coil spring, when broken, was easily removed with pinchers.

It was not a new expedient to anchor to the lens screw a spring used to position the guard. The Wells patent, No. 813,030, shows such an arrangement. The feature of screwing the lever down to the support with the head of its pivot on top to prevent wobbling was also used before in this art. See Bertolini model in evidence and patents to Pritchard, to Wells (Fig. 11) and to Terstegen, which also shows lever held between the support and the pivot head. Nor is it believed to have involved invention to reverse the screw, for example, of the Wells patent and cause it to project into the support from the lower side so as to establish a bearing between the support and pivot head. See Wells patent, No. 813,030. In the Finch patent, No.
