This is a bill in equity alleging infringement of the first seven claims of a patent relating to an automatic weighing machine, No. 766,004, issued on July 26, 1904, to Edward G. Thomas on an application filed on December 17, 1896. The respondent claims under a patent which, so far as this case is concerned, is agreed to be identical, No. 633,675, issued to the assignee of George W. Watson on September 26, 1899, on an application filed on March 11, 1898. It will be noticed that the application for the patent to Watson was filed after the application for the patent to Thomas, but that the patent to Watson was granted first. This is said to have been through an oversight on the part of the Patent Office; but we do not perceive that we are concerned in determining precisely how this happened, or that the record enables us' so to do, or that it would be of any substantial importance in this case, or to any party except the United States, to determine whether or not the patent to Watson was thus issued. After the patent to Watson issued, the case went to the Court of Appeals of the District of Columbia, under section 4911 of the Revised Statutes as amended by the act to establish the Court of Appeals for the District of Columbia, approved on February .9, 1893, c. 74, 27 Stat. 436 [U. S. Comp. St. 1901, p. 3391].- That court decided in favor of Thomas. 23 App. D. C. 65. We have no particular occasion to refer to that decision, except to the facts stated at page 67, which' indicate that the questions involved are not practically free from doubt. In the Patent Office, the Examiner of Interferences adjudged priority to Thomas. He was reversed by the Board of Examiners, who were again reversed by the Commissioner of Patents, whose decision in favor of Thomas was affirmed by the Court of Appeals.
No one claims that the decision of the Court of Appeals is conclusive on the issue here’; but it is maintained by the complainant that it is very persuasive. We should so regard it, and probably should follow it, .if the issues were the same as those before us, although the proofs were not obtained on examination and cross-examination as in the case here. In Prindle v. Brown,
The invention in this case lies almost entirely in the conception because it is apparent that, whén the conception had been fully explained, any person of ordinary skill in the art could put it into practical form.
Watson completed his conception in January, 1896. As to this conception, the complainant admits as follows, coupling it with its own notion of the sole issue in the case:
“It will not be denied, in the present controversy that Watson had conceived the invention, as found by the Commissioner and the Court of Appeals, by January, 1896, which is prior 1o the date of conception by Thomas. The sole issue, therefore, on this defense of prior invention, would seem to be whether Watson had sustained the burden of proof upon him to show the ‘reasonable diligence’ required by the statute.”
This is followed by a statement from the complainant that it was not contended in the proceedings in the Court of Appeals of the District of Columbia, and would not be contended here, “that Watson was not in possession of a complete conception of the invention as early as January 10, 1896.” It is also shown by both Watson and one Doble, for whom he was working, that in January, 1896, Watson explained the conception to Doble, and showed him drawings of the details of the mechanism covering each step in the series required to make an operative machine; and, referring to this, Doble testified as follows:
“Q. When Mr. Watson explained this drawing to you, did you understand the mechanism shown in it? A. I did fully.”
This drawing was preserved and produced before us, and no question is made as to the date of its origin nor as to its sufficiency in
As stated in the opinion of the Court of Appeals of the District of Columbia, Watson made no further effort with reference to the invention in question until January, 1897, when he made some working drawings, and nothing further thereafter until he filed his application for á patent. The view expressed by Mr. Justice Story in Reed v. Cutter, 1 Story, 590, 600, Fed. Cas. No. 11,645, based on certain expressions of the statute, that one who has the earliest conception, provided .he uses reasonable diligence in adapting and perfecting the same, may secure his patent, although the second inventor has in fact first perfected the same conception, seems to have been generally accepted, although we are not aware of any express provision of the present statute or any decision of the Supreme Court fully authenticating it. The rule, however, is given in Walker on Patents (4th Ed.) 126. He lays it down only as an equitable rule, and refers neither to any language of the statute nor any authoritative decision of the Supreme Court. However that may be, we are inclined to the opinion that Watson did not bring himself within any rule of that character. Therefore, Watson v. Thomas, 23 App. D. C. 65, already referred to, was no1 doubt correctly decided on the theory which we have stated, that the case is strictly one between two, each of whom originally, so far as the other was concerned, conceived the invention. Here, however, as we have said, we have a very different question. Can Thomas’ patent be sustained as against the public in view of the fact that, as the record stands, his conception does not go back of his application for his patent, while Watson, a long time previously, not only had a complete conception, but developed it to Doble in the way we have explained?
Of course, the law is thoroughly settled that a mere conception, not in some way demonstrated or communicated, does not amount to an invention under the statutes of the United States. This is so thoroughly, understood that we need hardly cite authorities for it. Mr. Walker seems to make some distinction between drawings and an oral description, based rather on circumstances than on any essential difference. At page 64 he says that, “in cases where the invention may be exhibited in a drawing or model, it will date from the completion of such a model or such a drawing as is sufficiently plain to enable those skilled, in the art to understand the invention.” In Loom Company v. Higgins,
*419 “An invention relating to machinery may be exhibited either in a drawing or in a model, so as to lay the foundation of a claim to priority, if it be sufficiently plain to enable those skilled in the art to understand it.”
This is a positive and broad statement, but in that case it was applied in favor of the patentee, so that we cannot assert positively that it goes beyond the rule favorable to patentees, as stated in Reed v. Cutter and by Mr. Walker, as we have already said. In Eames v. Andrews,
Three times the Circuit Court of Appeals for this circuit approached the precise question we have here, without being required to exactly meet it under the same or analogous circumstances. In Dececo Co. v. Gilchrist Co.,
It follows that it can hardly be said that there are sufficient authorities, either in the decisions of the courts or in the text-writers, to guide us clearly under the circumstances now before us. We must conse-' quently follow our own impressions with reference thereto. It seems to us that Watson completed this invention and expounded it in January, 1896, and that in this he went so far that the only thing needed to entitle him to a patent at that time was to employ some solicitor to put his application into the form required by the rules governing proceedings in the Patent Office. We cannot, therefore, resist the conclusion that Watson was a true inventor within the law; so that, in behalf of one who occupies the position of the public at large, and who is entitled to all the defenses to which one who is merely alleged to be an infringer is entitled, as is the condition of the respondent in this proceeding, Thomas cannot be held to have been “the original and first inventor,” within section 4892 of the Revised Statutes [U. S. Comp. St. 1901, p. 3384].
While what we have said states clearly to ourselves the case as we apprehend it, we think some further references to particular cases may be "necessary in order that no inferences may be drawn from this opinion beyond what we intend. The opinion of Mr. Justice Story in Reed v. Cutter,
“It is not necessary in order to complete an invention that there be a machine constructed, or even a model. The invention may be disclosed by the application sufficiently to entitle the patentee to priority as of the date of the application, or it may have been disclosed by a machine or model, or in some other concrete manner, a long time before the application was filed, so that the patent whenever applied for would go back to that disclosure.”
The words “or in some other concrete manner” are broad enough to include a case like this at bar; and in Prindle v. Brown it was not necessary to determine the precise question now before us. We may add right here that the authorities, in their present condition, do not sustain the extreme view found in Robinson on Patents, vol. 1, § 126, which might in effect render invalid a patent for a machine, otherwise lawfully issued, because not based on one actually constructed and practically operated. A careful examination of Agawam Company v. Jordan,
Therefore, as we have already said, we find nothing in all the decisions brought to our attention which permits us to hold that what was disclosed by Watson to Doble in January, 1896, was not a complete invention under the patent law, with the same effect in the way of anticipation as though it had received publication on that date in a foreign scientific journal, or which requires us to leave a possibility, and even a probability, that any one assuming to have been a later inventor might not, in these days of great mechanical activity and of unlimited facility of communication, have become informed of what Watson had done, in some manner which neither the court nor the parties to the litigation have discovered, and thus have availed himself of what was already known at least to some person in the art, instead of having conceived anything new by his own mental operations. In order not only to guard the community from the evils of surreptitious information thus obtained, but also from the possibility of collusion, as well as
Let there be a decree dismissing the bill, with costs for the respondent, under rule 21.
