Opinion

.Mr. Justice Morris

delivered the opinion of the Court:

This is an appeal from the decision of the acting Commissioner of Pate:its in an interference case wherein the subject-matter of controversy is described to be — a sheet-metal cap for closing bottles and the like, having in its sides plain faces indented to form inwardly extending lugs and longitudinally crimped between said faces to afford a good holding-surface.

The appellees, Edmund Hoffman and Robert Portes Erist, hold a patent for this invention, for which they made application on March 29, 1898, and which was issued to them on November 1, 1898. The appellant, Philip Lindemeyr, filed his application on March 13, 1899. He was, therefore, the junior applicant and required also to; overcome the effect of a previously existing patent. The burden thus imposed upon him it is sought on his behalf to lessen by reference to the fact that his present application is no more than a proper division of a previous application filed by him on 'April 1, 1898, wherein the matter here in controversy is embodied and distinctly shown, but not specifically claimed, and which application, after having been permitted to lapse in consequence of failure to pay the final fee required by the Patent Office, was duly renewed, and allowed to go to patent on March 14, 1899, one day after the filing of the application in the present case. Upon the theory, therefore, that the present application is no more than a division of the previous one, made while that previous application was pending and before it had gone to patent, a proceeding authorized by the rules and practice of the Patent Office, it is claimed that the applications of both parties for the invention now in controversy were both pending at the same time. But even upon this theory, the appellant Lindemeyr remains the junior applicant, his first application being three days later than that [3]*3of Ms opponent's, and the burden of proof in any event is upon him. The facts which have been stated are important only in the determination of the amount and character of the proof required from him in order to enable him to prevail over his opponents.

In his preliminary statement Lindemeyr alleged 'that he had conceived, disclosed; and reduced the invention to practice in May of 1896, and that a few caps had been made and put in use. The preliminary statement of Hoffman and Frist, alleged conception by them in 1891, disclosure in 1894, construction of machinery to manufacture the article in August or September of 1S97, and the actual manufacture of the article by September 15, 1897; and that manufactured product was put upon the market on May 11, 1898.

When, after testimony taken, the cause came on for determination, the examiner of interferences held that Lindemeyr, although his proof was somewhat weak, had established his conception and reduction to practice in May of 1896, according to the claim' of his preliminary statement; that the alleged conception of the invention by Hoffman and Frist in 1891, being shown by no other testimony than their own, could not be admitted; that they did, however, sufficiently prove that they had a conception of it in 1894; that what they did then was not a reduction to practice; and that their first reduction to practice was only the constructive reduction evidenced by the filing of their application on March 29, 1898. The examiner thereupon held that Hoffman and Frist were the first to conceive the invention and the last to reduce it to practice; and that their priority of conception could not avail them as against one who had in the meantime entered the field, conceived the invention, and reduced it to practice, unless they were then in the exercise of due diligence. He found that they were not in the exercise of due diligence, and that they had done nothing in the matter from 1894 to 3897. He, therefore, awarded judgment of priority of invention to Lindemeyr. Incidentally, also, he ruled that Lindemeyr was required to prove his case only by a preponderance of evidence; and also that his patent [4]*4issued on March 14, 1899, was no bar to the present application, either on the ground that the present application, if allowed, would result in a duplication of patents, or on the other ground that the invention being shown in the previous patent and in the application therefor, the failure to claim it should be regarded as an abandonment of it to the public.

The board of examiners-in-chief found that, while Lindemeyr had a conception of the invention in 1896, there was no reduction to practice by him before the constructive reduction involved in the filing of his 'application on April 1, 1898. And they found conception by Hoffman and Frist in 1894, and constructive reduction to practice by them in their application filed on March 29, 1898. They were, therefore, held to be the first to conceive and the first to reduce to practice, and consequently to be entitled to a judgment of priority of invention, which was awarded to them, and the decision of the examiner of interferences was reversed. The board of examiners did not deem it necessary to pass upon the question of actual reduction to practice by Hoffman and' Frist before the filing of their application, and they left that matter in doubt.

Upon appeal to the Commissioner of Patents, the acting Commissioner, who sat in his place, held that there was sufficient proof of reduction to practice by Hoffman and Frist in 1894; and consequently that they antedated Lindemeyr in every respect. He, therefore, affirmed the decision of the board of examiners in awarding priority of invention to Hoffman and Frist.

From the decision of the acting Commissioner of Patents the cause now comes here on appeal.

While the Commissioner of Patents and the board of examiners-in-chief concur in the award of priority! of invention to the appellees, Hoffman and Frist, thereby reversing the judgment of the examiner of interferences, which, as stated, was- in favor of Lindemeyr, it is apparent that no two of the tribunals of the office are in accord as to the grounds of adjudication. There is one thing, however, in which they all agree; and that is, in the award of priority [5]*5of conception of the invention to the appellees, not as of the year 1891, at which time they claim to have conceived it, and as to which there is no proof outside of their own unaided testimony, but as of the year 1894, when they claim to have made disclosure and a sketch of it, and possibly some attempt to reduce it to practice. This priority of conception is conceded on behalf of Lindemeyr. At all events, it is not controverted; and it may be assumed to have been satisfactorily established by the testimony. This conception antedates that of Lindemeyr by two years.

The point of controversy, therefore, is that of reduction to practice.

The appellees claim an actual reduction to practice! by them in 1S94; the appellant., a similar reduction to practice in 1896; and both were more or less, active in the general subject-matter, to. which the issue of the interference belongs, during the years 1897 and 1898. If it were satisfactorily shown by the testimony that there was actual reduction to practice by the appellees in 1894, as the assistant Commissioner of Patents found to be the fact, this, of course, would be decisive of the case.

If it were not so shown, then it would be proper to examine what was clone by Lindemeyr in 1896; for it does not appear that anything was done in the meantime by either party.
