71 F. 701 | U.S. Circuit Court for the District of Nebraska | 1896
The bill in this case is based upon letters patent Tío. 433,531, applied for by Samuel W. Martin, and issued to the complainant corporation, as the assignee of the inventor, and covers an improvement in the machinery of windmills, it being-charged that the defendant company is engaged in the manufacture and sale of windmills which embody the improvement covered by the above-named letters patent, and is therefore an infringer upon the rights of complainant. To this bill the defendant company answers, denying infringement, and averring that the combination described in the first claim of the Martin patent, which is the one relied on by complainant, lacked novelty, and had been anticipated by other known and patented devices and combinations.
Upon the conclusion of the argument by counsel, which very fully covered the points thus stated, the court called attention to the following statement, found in the specifications of the letters patent, and asked counsel whether, upon the face of the patent, it was not shown to be void, the statement being as follows, and being found at the conclusion of the descriptive part of the specifications, and immediately preceding the portion setting forth the claims of the applicant, to wit:
“The invention is in practical operation and on the market in considerable numbers, and the facts here, stated with regard to its operation are such as have been ascertained from commercial experience with it.”
Section 4886 of the Revised Statutes is as follows:
“Any person who has invented or discovered any new and useful art, machine manufacture or composition of matter, or any new and useful improvement thereof, not known or used by others in this country and not patented or described in any printed publication in this or any foreign country before his invention or discovery thereof, and not in public use or on sale for more than two years prior to his application, unless the same is proved to have been abandoned; may, upon payment of the fee.s required by law, and other due proceedings had, obtain a patent therefor.”
Under the provisions of this section, the defense of abandonment is separate and distinct from that of having been in public use or on sale for a period exceeding two years; and, in section 4920, it is further enacted that the defendant, under the general issue, upon giving 30 days’ notice, may prove:
“Fifth. That it had been in public use or on sale in this country for more than two years before his application for a patent, or had been abandoned to the public.”
In Elizabeth City v. Pavement Co., 97 U. S. 126-134, it is said:
“An abandonment of an invention to the public may be evinced by the conduct of the inventor at any time, even within the two years named in the law.”
In the case of Fruit-Jar Co. v. Wright, 94 U. S. 92, it is expressly decided that, under the act of 1839, there were two defenses, among others, upon the issue of the validity of a patent, to wit: Purchase, sale, and prior use of invention for a period of two years antedating the application of a patent; and, second, an abandonment of the invention to the public.
In Andrews v. Hovey, 123 U. S. 267, 8 Sup. Ct. 101, the provisions of the acts of 1836, 1839, and 1870 are collated, compared, and explained; and it is shown that under the provisions of the act of 1870, which now forms sections 4886 and 4920 of the Revised Statutes, the defense of abandonment to the public is separate and distinct from that of prior use, and that it may be proved by evidence showing the purpose to abandon the.invention to the public, and that, if thus" proved, it will be a defense, although the abandonment took place within the two-year limit applicable to cases of prior public use ox-sale. This case again came before the supreme court upon a petition of rehearing, and a full review of the decided cases was had, the result being that the prior ruling was sustained. See 124 U. S. 694, 8 Sup. Ct. 676.
Upon the face of the patent now under consideration, it appears that,previous to the date of the filing of the application, the invent- or had put the invention into practical operation; that considerable numbers of mills embodying the improvement had beenput upon the market for sale; and that the facts recited in the application, as evidence of the value and usefulness of the combination, had been ascertained from commercial experience with it. These statements preclude the idea that the use made was experimental. The recitals show that the invention or combination had been perfected so as to make it practical. Numbers of mills liád been put upon the market, and upon the knowledge derived from this extensive commercial use the patentees relied for proof of the successful working of the combination. Certainly, the facts thus stated by the applicant are strong evidence of abandonment. If an inventor, after perfecting his invention, places it upon the market in large or considerable numbers, and sells to all who desire to purchase, and continues so to do for months, without applying for a patent, no other conclusion can be drawn than that he does not intend to apply for a patent; and he cannot be permitted, after having made public the knowledge of his invention, and induced many persons to purchase, to then conclude that the invention may be worth patenting, and that he will debar the public from using the knowledge they have acquired from him by procuring the issuance of a patent. It is well settled that delay in applying for a patent may he explained and be excused by reason of sickness or inability to furnish the means needed to procure a patent, and also a sale or sales may be made under circumstances which are not inconsistent with an intent to apply for a patent. Primarily, ¡he defense of abandonment is based upon matters of fact, and each case will depend upon the facts proven therein; the legal conclusion being that if, in fact, the inventor did abandon his invention to the public, then he cannot afterwards obtain a valid patent, therefor.
I n this case the facts recited on the face of the patent must be held to tie true as against the inventor and his assignee. The evidence shows that Martin was in the employ of the complainant corporation; that Mast, Foos & Co. is a corporation with a paid-up capital of 8200,000. and largely engaged in the manufacture of windmills; that beginning in December, 1888, the work upon the improvement devised by Martin was done in its shops; and that Martin assigned his tights to complainant before the patent was issued. There is nothing developed in the evidence tending to explain away the delay in applying for a patent, or to show that the complainant corporation engaged in the sale of the machines for any other purpose than to make money out of the same, or, in other words, as a purely commercial undertaking; or, to put it in the language used by counsel for complainant in bis brief, “complainant had been manufacturing and
But, as already stated, the facts constituting proof of abandonment are recited on the face of the patent; and when complainant introduced the patent, in support of the averment in the bill that complainant was the owner of valuable letters patent covering the Martin combination, it was the duty of the court to examine the patent to sqe whether, in form, they were legal and valid; and, in so doing, the court became advised of a condition of facts which, in the.
