This is a bill in equity. It was filed August 1, 1890. Complainant is. by assignment tlie owner of two patents for certain improvements in windmills, which it alleges have been, and are being continuously, infringed by the defendants. The prayer of the bill 'is for an injunction, and for an accounting as to damages and рrofits. No preliminary injunction, was asked or allowed, and upon final hearing the bill was dismissed upon grounds stated in an opinion by District Judges Wage and Severens.
In the view we have taken of the evidence, it is only necessary for us to determine whether the laches of the complainant and it's assignors has beеn such as will prevent a court of equity from entertaining this bill. One of the patents owned by complainant is for an improvement in windmills, issued December 19, 1876, on an application filed August 14, 1876, and was issued to L. D. Anderson,
“What I claim as now, and desire to secure by letters-patent, is as follows: In a windmill, the shoe or brake, d, in combination with the yane, B, and shaft, A, of the windmill, substantially as and for the purposes specified.”
The other patеnt involved is patent: No. 220,514, dated October 14, 1879, and was issued to Harrison Woodmanse, assignor of the Anderson patent, and Samuel Lebkieker, for an improvement in windmills by providing a lever in connection with a brake wheel so arranged as to be operated by a projection upon the inner end of the vane, for the purpose of rendering the brake more effective. Complainant's suit must: turn niton the alleged infringement of the claims of the Anderson patent. The claim of the Woodmanse & Lebkieker pаtent involved is the first, which reads as follows:.
“The brake shoe, b: the lever, c, in combination with the wheel, a, and vane, c, substantially as and for the purposes specified.”
This slightly different arrangement of the leverage, in the application of the brake to the shaft, from that claimed in the Anderson patent, is noi satisfactorily shown to have been infringed by the brake used by defendants.
In 1873, Bradley S. Williams, W. H. Pendleton, Kirk A. Smith, and C. M. Hobbs, under the style of Pendleton, Williams & Co., he: gan' the business of making and selling windmills at Kalamazoo, Mich. That business has been steadily pursued, and the Williams Manufacturing Company are but the successors of the original firm of Pendleton, Williams & Co. Hobbs and Smith, of the original firm, sold out: in 1879. The defendant Homer Manvel bought in in 1874, and the other individual defendants bought an interest in 1880. From 1880 the firm was composed of B. S. Williams, Homer Manvel, and M. B. Williams, and did business as B. S. Williams & Co. until 1889, when the present corporation was: organized, the same рersons being stockholders and officers. The evidence clearly establishes that, as early as 1874 or 1875, the defendants, or tliclr predecessors in business, began making a brake, and applying it to their windmills, which is substantially l.be same brake which the present corporation is making, and this brake, with occasional slight improvements, has been continuously made and used on the windmills sold by defendants, or those to whom it has succeeded, for a period of about 15 years before this suit was brought. Now, if it he conceded that the patents owned by complainant were not anticipated by either the Bignell patent or any of the others claimed as anticipations, a point by no means clear, and that the brake made and sold with the defendants’ mills does infringe both or either оf the complainant’s patents, we then have a, case where suit has been delayed against an infringer openly arid publicly engaged in selling a rival and competitive mill to that made and sold by complainant and its assignors for a period of 14 yeаrs after issuance of the Anderson patent, and of about 11 years after the .Woodmanse and Lebkieker improvement. No excuse for this long delay is shown. Mr. W'oodmanse, who is the manager of
The ground uрon which a court of equity will take cognizance of a suit for an infringement of a patent is the relief through an injunction. There is nothing so peculiar to a suit for damages and profits for infringement of a patent as will, independently of some recognized ground of equitable jurisdiction, justify a court of chancery in assuming jurisdiction. It must appear that the legal remedy at law is inadequate, and if the case is one in which equitable relief by injunction is inappropriate, as where the patent has expired, оr where the circumstances are such as to justify a court
Aside from the fact that no preliminary injunction was applied for or allowed, and that when the final hearing was had plaintiff Anderson’s patent had expired, we think that the conduct of complainant, and those to whose rights it has succeeded, has been such as to require a court of equity to refuse it any relief whatever. Reasonable diligence as well as good faith are necessary to call into operation the powers of a court of equity. Maxwell v. Kennedy,
“Courts of equity, it lias often been said, will not assist one wbo bas slept on bis rights, and shows no excuse for his laches in asserting them.”
In the very late case of Keyes v. Mining Co., 15 Sup. Ct. 772, the doctrine of McLaughlin v. Railway Co., and Lane & Bodley Co. v. Locke, was followed, and a complainant who had delayed for nearly 17 years was repelled from court as guilty of inexcusable laches. Neither is it important that the defense of laches was not formally set up in the answer. Laches is a defense Avhich may be made by demurrer, or by plea, or by answer, or presented by argument, either upon a preliminary or final hearing. Maxwell v. Kennedy,
The decree of the circuit court dismissing complainant’s suit will be affirmed.
