Opinion

HINCKS, District Judge.

This is a bill brought to restrain the alleged infringement of patents for electric switches, as follows: No. 1,240,459, issued to Klein, September 18, 1917; No. 1,651,035, issued to Meuer, November 29, 1927 (hereinafter called “first Meuer patent”); and No. 1,783,665, issued to Meuer, December 2, 1930 (hereinafter called “second Meuer patent”). To the complaint the usual defenses of invalidity and noninfringement have been imposed. And, in addition, the defendant, to the claim of infringement of the Klein patent, pleads the defense of laches.

The plaintiff bases its claim of infringement upon three switches of the defendant’s manufacture in evidence as Exhibits A, B, and 22.

For its charge of infringement in respect of switch A, plaintiff relies upon claims 1, 2, 4, 5, and 6 of the Klein patent, and upon claim 1 of the first Meuer patent. Its charge of infringement in respect of switches B and 22, the plaintiff bases upon claims 1, 5; and 6 of the Klein patent, and claims 2, 3, and 22 of the second Meuer patent.

Klein Patent.

All of the claims of the Klein patent are for combinations. Claim 1 reads as follows : “1. A switch for concealed mounting, comprising, in combination, an insulating easing, a snap switch meehanisni inclosed therein and having an operating member extending therebeyond, a bushing having an opening to receive said operating member, means for securing said bushing to said easing, and adjustable means carried by said bushing for clamping said easing to a suitable support.”

The object of this patent is stated to be (inter alia) to provide improved means for attaching the switch to a support. Indeed, the plaintiff throughout trial and argument has emphasized the fact that the great value and distinguishing characteristic of this patent is its adaptability for “one-hole mounting.”

This feature of the switch is obtained by uniting with the switch a means for mounting consisting of a hollow metal bushing built into the top of the casing of the switch. Through the hollow core of the bushing extends the operating member of the switch. The exterior of the bushing is threaded and equipped with a nut. Thus the switch is peculiarly adapted for use in canopies; for notwithstanding any irregularity in the surface of the canopy, the means disclosed permit the switch to be snugly and conveniently mounted without other adaptation of the canopy than the single aperture for both the mounting and operating means. The result is that the switch behind, or inclosed within, a panel or canopy can readily be mounted by one person simply by inserting the bushing through an aperture of the panel or canopy, and by screwing the nut upon the bushing [151]*151from the outside, leaving the operating member also accessible from the outside.

The evidence discloses that the device of the patent for a time enjoyed considerable commercial success. In the validity of the patent also the trade to some extent acquiesced, and several manufacturers were licensed by the plaintiff. Such acquiescence,’ however, was by no means general.

.The claims relied upon all state combinations, the elements of which it must be conceded are without novelty. The defendant contends that the combination itself is wholly lacking in novelty and patentable invention.

It may well be doubted whether any one of the references upon which the defendant relies shows a complete anticipation of all of the elements of the combination. Thus Nevins, No. 553,014, lacks the bushing for mounting; also the insulated casing. Hepburn, No. 743,281, lacks the insulating easing ; also the snap-switch mechanism and the bushing for mounting. Hewlett, No. 833,-208, discloses a switch not completely encased and apparently lacking in a snap-switch mechanism. And Schaefer, No. 959,-886, seems to lack the snap-switch mechanism, and its easing also is only partly insulated. Greengard, with his filing date of October, 1910, was preceded by Klein, whose combination I find to have existed as early as January, 1910. But it is not necessary to pass upon the novelty of the combination in view of my conclusion that it lacks invention.

Clearly so much of the combination as comprises the switch mechanism, with its operating member and the easing, involves nothing more than a matter of design. Cutler-Hammer v. Beaver (C. C. A.) 5 F.(2d) 457. But the plaintiff strenuously insists that patentable invention was required to add to this combination the means for mounting described above. This contention I cannot sustain.

The .patentee having before him an inclosed switch in compact form was confronted with the problem of mounting. With ordinary mechanical experience, his first thought would lead him to consider the suitability of such conventional devices as bolts or screws. Having in mind a mounting device suitable for metal canopies now coming into vogue, he discards the screw as unsuitable for use with metal. A plurality of bolts has obvious disadvantages. So he prefers a single bolt. For added convenience and simplicity, instead of a loose bolt which of itself would require means of connection with the switch unit, he builds a bushing exteriorly threaded into the switch inclosure. This, clamped with the nut from the exterior, furnishes the mounting. Surely, thus far no inventive genius has been required.

But the problem is only partly solved. The operating member from the switch must also be accessible from the exterior. It must penetrate the canopy either by the aperture for the mounting bushing, or through another aperture. It being of obvious advantage to avoid additional perforations of the canopy, the sole remaining problem of the patentee is to bring the operating member through the aperture already occupied by the mounting bushing.

It is not necessary to decide whether true invention would have been disclosed by the successful solution of this problem without any aid from the prior art; for in fact the prior art did disclose the solution. Thus Shaefer, Hewlett, and Hepburn, all referred to above, each discloses the device of an operating member, housed in a hollow bushing penetrating the panel of the mounting so that the mechanism inside the panel is operable from without. To correlate a device thus borrowed from the art with his other elements, though accomplished with conspicuous success, was a matter of skillful design rather than invention. Vanderburgh v. Truscon Co., 261 U. S. 6, 43 S. Ct. 331, 67 L. Ed. 507; Bryant Electric Co. v. Reno Sales Co. (C. C. A.) 16 F.(2d) 797; McGill Mfg. Co. v. Leviton (D. C.) 36 F.(2d) 228.

The situation therefore seems to be one for the application of the familiar rule that it is not invention to combine old devices without producing any new mode of operation. Stimpson v. Woodman, 10 Wall. 117, 19 L. Ed. 866; Victor Cooler Door Co. v. Jamison Cold Storage Door Co. (C. C. A.) 44 F.(2d) 288; Concrete Appliances Co. v. Gomery, 269 U. S. 185, 46 S. Ct. 42, 70 L. Ed. 222; Atlantic Works v. Brady, 107 U. S. 192, 2 S. Ct. 225, 27 L. Ed. 438.

The plaintiff contends that its combination is patentable, in that it produces a new function and better results within the rule of Webster Loom Co. v. Higgins, 105 U. S. 580, 26 L. Ed. 1177.
