Opinion

HAZEL, District Judge.

The complainant acquired ownership, by assignment, of letters patent No. 4(53,599, granted November 17, 1891, to Charles Emons “for a wagon jack.” The application was filed August 19, 1890. The defendant is owner of letters patent No. 432,230, dated July 15, 1890, No. 457,183, dated August 4, 1891, and No. 558,589, dated April 21, 1896. The patent of July 15, 1890, was involved in interference before the application for the complainant’s patent. The interference was determined in favor of Charles Emons, complainant’s assignor, a priority of invention was awarded to the interferant, and the patent in suit was thereafter issued to said Emons. The defendant’s first application was filed May 23, 1890. The defendant by his answer denies infringement, and alleges anticipation, prior use, and abandonment. JBoth patents are for a wagon jack, comprising a base plate and hollow standard, the vertical moving bar therein carrying the stepped head, the lever of the fulcrum bar pivotally bearing on the base plate. The only difference, so far as the wagon jack in question is concerned, is that in defendant’s constructions, instead of having a solid base plate, they have base plates formed with arched ribs, and their standard does not project centrally from the base plate; the fulcrum rod is not pivoted on the lug projecting from the base plate; but in one of the patents one of the ribs of the base, and in the other the rod, is not pivoted at all, but hooked to the base, and has an additional L-shaped step to its head. In defendant’s first patent the fulcrum bar is supported at its center. The slight structural differences in these patents, readily observable from an inspection of the jacks, would not avoid infringement, were the patent allowed to stand unimpeached for any other cause.

The second question presented is whether the Emons patent is anticipated by many prior inventions shown by patents in evidence. An examination of the anticipatory patents shows nothing sufficient to overcome the presumption which arises in favor of the inventor by the issuance to him of the patent by the patent office and the decision in the interference proceedings. The principal controversy relates, therefore, to the third defense of prior use and abandonment. In his proofs the defendant relies mainly on the latter defense. It is claimed that the wagon jack for which the patent in suit was granted had been on sale and in use for more than two years before the filing of the application for the patent therefor, and that his alleged invention had been abandoned by him to the use of the public before his application for letters patent was made. It is settled that prior public use or sale is a question of fact which may be established by a single witness, and if by his testimony a single sale is satisfactorily proven, or the article patented was in public use earlier than two years before the application for that patent, judgment must be rendered for the defendant. The reason for this rule is obvious. Whenever an inventor by his efforts, with the expenditure of his time [185]*185and moans, by Ms application to introduce an invention to the public, not having been known or used previous to such invention, does devise and create something new and useful, the law jealously guards the rights ,and interests of the inventor, and protects him and his patent, in his legal rights, from the attacks, jealousies, and suspicions of rival inventors and manufacturers. Defenses interposed in an action for infringement of the rights guarantied by the issuance óf a patent by the government ought to be carefully scrutinized and considered. The defense of prior use and abandonment of a patent, although easily pleaded in answer to complaint for infringement, must yet be established by preponderating proof, clear, satisfactory, and beyond reasonable doubt. Cluett v. Claflin (C. C.) 30 Fed. 922; Mack v. Manufacturing Co. (C. C.) 52 Fed. 821; Washburn v. Gould, 3 Story, 122, Fed. Cas. No. 17,214; Waterman v. Thompson, 2 Fish. Pat. Cas. 461, Fed. Gas. No. 17,260; Barbed-Wire Patent Case, 143 U. S. 284, 12 Sup. Ct. 443, 36 L. Ed. 154; Coffin v. Ogden, 8 Wall. 120, 21 L. Ed. 821; Cantrell v. Wallick, 117 U. S. 689, 6 Sup. Ct. 970, 29 L. Ed. 1017. If, however, the testimony in the case is satisfactory, — that is to say, if it clearly establishes beyond a reasonable doubt that the inventor is unmindful or regardless of the protection which the laws accord him in recognition of his inventive genius, his public services, — and if, therefore, before the invention ripens into a patent, he, of his own volition, relinquishes his exclusive right to the protection which the law affords him, he thereby waives control over his invention or discovery. The public by right takes to itself the beueiit which the neglectful inventor has the right to restrict to such use only as would remunerate him for the time and service which lie gave — the endeavor and energy which he displayed — “in the finding out or creating some thing new and useful which did not exist before by the operation of the intellect.” Whether the inventor intended to abandon his invention by public use must be ascertained from the particular facts and circumstances of each case. The inventor’s own direct act is most significant of his intention. The esteem in which he holds his invention or discovery is ascertained by his conduct ¡owards the thing invented. If he regards his invention as useful, and one for which remuneration by right ought to inure to him, he promptly applies for protection for his invention by complying with the requirements of law. It is demanded of Mm that, in consideration of the right to patent extended to him by the government, he comply with the prevailing laws enacted, not only for his safety, but for the benefit of the public. It is well said in Wright v. Postel (C. C.) 14 Fed. 352, that “one who desires a patent must be vigilant in reducing his invention to practical form and applying for letters. The patent laws are intended for the benefit of the public as well as of patentees. They are designed to stimulate invention, for the common advantage. It is therefore the duty of inventors to use reasonable diligence in reducing their conceptions to practice, and applying for patents, when desired. They cannot neglect it without danger to their rights.” The burden of proof in this case rests upon the defendant to establish prior sale, public use, and abandonment. It is necessary for him to show that complainant’s invention was unmistakably [186]*186- dedicated to the use of tbe public by the inventor, or with Ms consent or acquiescence, prior to August 19, 1888.

What are the salient facts of this case with reference to public use and sale for more than two years before application was made for the letters patent in suit? The inventor testified that he conceived his invention on or about August 1, 1888, and that on August 25th thereafter be completed the wagon jack described in the patent issued to him on his application for a patent dated August 19, 1890. At the time the jack was completed he was in the employ of Reynolds & Lang. He showed the completed jack to three fellow employés, none of whom gave testimony, although two of them were alive at time of trial. On the following day, Emons, the inventor, exhibited the completed jack to one Porter, who afterwards became his father-in-law. Acting on his suggestion, he made a brief memorandum on the last ruled page of a memorandum book, declaring that on August 25, 1888, his three fellow workmen saw an iron wagon jack invented by Charles Emons.
