Opinion

Mr. Chief Justice Shepard

delivered the opinion of the Court:

This is an appeal from the decision of the Commissioner of Patents in an interference case. The issue involved reads as follows:

“1. In a device of the class described, the combination with the series of connected steps, of ways in which said steps travel, and a driving mechanism intermediate the ends thereof engaging with both the ascending and descending parts of said series.

“2. In a device of the class described, the combination with a series of steps, of ways in which said steps travel, of a sprocket chain connecting said steps, and a sprocket wheel interposed between the ascending and descending series of said steps intermediate the ends thereof and meshing with said chain on both sides.

“3. In a device of the class described, the’ combination with a series of steps, and ways in which said- steps travel, of a [479]*479sprocket chain connecting said steps, a sprocket wheel interposed between the ascending and descending series of said steps intermediate the ends thereof and meshing with said chain on both sides thereof, and means for applying power to said sprocket wheel to drive the steps.

“4. In a device of the class described, the combination with the moving sections, of guides for said sections stationary relative to the movement thereof supporting said sections at both ends throughout their entire course, and driving mechanism engaging the sections between the two ends of the course and at a point where they change direction of movement, said driving device also engaging the sections on the return run.

“5. In a device of the class described, the combination with the sections moving throughout their course in a single vertical plane, of guides for said sections stationary relative to the movement thereof and supporting them at both ends throughout their entire course, and driving mechanism engaging the sections between the two ends of the course and at a point where they change direction of movement, said driving mechanism also engaging the sections on the return run.

“6. In a device of the class described, the combination with the sections moving throughout their course in a single vertical plane, of guides for said sections stationary relative to the movement thereof and supporting them at both ends throughout their entire course, and driving mechanism engaging the sections between the two ends of the course and at a point where they change direction of movement, said driving mechanism consisting of a sprocket wheel engaging said steps on both the forward run and return run.

“7. The combination in a moving platform or stairway, of the moving steps, tracks therefor, and a driving mechanism engaging the steps between the two ends of the platform or stairway and at a point where they change direction of movement, said driving device also engaging the steps on the return run, substantially as described.

“9. The combination in a moving platform or stairway, of moving sections, guides therefor, and a driving device engaging [480]*480the sections, between the two ends of the platform or stairway and at a point where they change direction of movement, said driving device also engaging the sections on the return run, substantially as described.

“10. In a device of the class described, the combination with an endless carrier of guiding and supporting mechanism for said carrier’, and driving mechanism intermediate, the ends thereof engaging with both the ascending and descending portions of said carrier.”

The application of the appellant, Charles D. Seeberger, was filed October 22, 1901; that of the appellee, James M. Dodge, on January 22, 1898. To sustain the burden of proof imposed by his later date of application, Seeberger offered evidence tending to show a conception of the invention about May 1, 1895, coupled with diligence thereafter in perfecting the invention and reducing it to actual practice. Dodge relied upon the constructive reduction obtained by filing his application, and a stipulation of counsel to the effect “that on December 7, 1897, the subject-matter shown and described in the application of James M. Dodge, as originally filed January 22, 1898, was fully disclosed and explained by the said James M. Dodge to Henry Howson, of the firm of Howson & Howson of Philadelphia, attorneys for said J. M. Dodge, with instructions to proceed to prepare application for patent.”

Regarding the evidence of Seeberger as sufficient to show diligence, the Examiner of Interferences awarded priority to him. On appeal to the Examiners-in-Chief this decision was reversed, and theirs, on further appeal, was affirmed by the Commissioner.

All agreed that Seeberger had shown his conception of the invention in May, 1895, thereby preceding Dodge’s agreed date by more than two years, and the finding was acquiesced in by the latter. The determination of priority, therefore, was made to turn upon the question whether Seeberger was exercising diligence in reducing his invention to practice at the time that Dodge entered the field.

[481]*481Before passing to its consideration it is necessary to dispose of a preliminary question suggested in the reasons of appeal.

Seeberger contended in the Patent Office, and renews the contention here, that the invention as claimed by him was not disclosed or claimed in the original application of Dcxlge, and was only introduced therein by amended claims made after the former’s application had been filed, wherefore the latter is not entitled to the benefit of a constructive reduction to practice as of the date of filing. If well founded this would entitle Seeberger, who was the first to conceive, to the benefit, also, of the earlier reduction to practice, and inquiry into the question of his diligence would become unnecessary.

Ordinarily, where the point has been raised, whether the application of one of the parties was broad enough in the terms of its specification and claims to embrace the invention of the other, and especially where the invention is one of elaborate and complicated mechanism, the decisions of the expert tribunals of the Patent Office in respect of identity have, for obvious reasons, been accepted as conclusive. Stone v. Pupin, 19 App. D. C. 396, 400; Schupphaus v. Stevens, 11 App. D. C. 548, 555; Ostergren v. Tripler, 17 App. D. C. 557, 559; Luger v. Browning, 21 App. D. C. 201, 204; Herman v. Fullman, 23 App. D. C. 259, 265. On the other hand, it has been said that in extreme cases where palpable error has been committed such a decision might be reversed. Swihart v. Mauldin, 19 App. D. C. 570, 573. In a case of peculiar character, also, a decision has been reversed under which one party was permitted by amendment to broaden an application for a specific invention into a generic one and thereby dominate another and different specific invention contained in the later application of another. Bechman v. Wood, 15 App. D. C. 484, 504. Clearly, this is not one of the extreme cases above referred to, nor do the amendments of the claims of Dodge, that were from time to time permitted, bring it within the scope of the case last cited.

Dodge made no change in the description of his invention as set out in the specifications of his application, but was from time to time allowed to make amendments of his claims, most [482]
