In re Marconi, 38 App. D.C. 286, 1912 U.S. App. LEXIS 2125 (D.C. Cir. 1912).

Opinion

Mr. Chief Justice Shepard

delivered the opinion of the Court:

This is an appeal by Guglielmo Marconi from the decision of the Commissioner of Patents rejecting the following claims of an application for the reissue of a patent:

“17. In a wireless telegraph transmitter, the combination of two rotatable members, teeth on the adjacent portions thereof, an oscillation circuit connected with said rotatable members, and means for rapidly rotating said members so that the teeth shall be caused to pass one another in opposite directions.

[288]*288“18. A spark-gap device comprising movable terminals and means for simultaneously rotating said terminals toward and away from each other, for the purpose of making and breaking a spark, substantially as described.

“19. In a wireless telegraph transmitter, the combination of two rotatable disks adapted to rotate in the same direction, teeth on the adjacent peripheries thereof, an oscillation circuit connected to said disks, and means for rapidly rotating said disks so that the teeth may be caused to pass one another in opposite directions, substantially as described.”

The patent No. 935,381, for which the reissue is applied, was granted September 28, 1909, on an application filed October 1, 1907. A British application for the same patent was applied for February 25, 1907. It relates to transmitting apparatus for wireless telegraphy, and specially to means for creating high frequency alternating currents. While it discloses a sufficient foundation for the broad claims now under consideration, the claims cover the specific form of the invention.

The revolving wheel as shown is formed of two metal disks, with equally spaced teeth projecting radially outward from their peripheries. These are fixed side by side, but insulated from each other, the teeth of one disc being spaced midway between the teeth of the other, and the bodies of the disks are respectively connected to the two poles of the current generator. Revolving in the same plane and in the same direction as the generator wheel, and in close proximity to it, but not in contact with it, is a toothed collector consisting of a plain metal disk, the outer rim of which is broad enough to carry teeth which will project over the teeth of both disks of the generator wheel, the distance between the teeth on this collector wheel being the same as that betwen the teeth of either of the two disks of the generator wheel. The electro-motive force of the source of electricity employed should be sufficient to cause the current to jump the small air space between the teeth of the generator wheel and the teeth of the collector wheel [289]*289as these pass each other when revolving close together; the wheels turning in the same direction.

Marconi also filed another application on March 31, 1909, relating to transmitting apparatus for wireless telegraphy, in which the discharge takes place across a small gap between discontinuous metal surfaces in relative motion at a very high speed.

In the specific form described and shown, the moving surfaces consists of pegs or studs on the adjacent faces of two parallel disks fixed to two shafts in a line with each other and revolved in opposite directions, the shafts being mounted in insulated bearings.

Clifford D. Babcock filed an application July 17, 1907, describing an apparatus for a transmitter for wireless telegraphy, in which the disks provided with studs on their adjacent faces rotate in opposite directions. On July 12, 1909, while both of Marconi’s applications were depending, an interference was declared between his later, or second, application and Babcock’s. The issue was declared in the following counts:

1. In a wireless telegraph transmitter, the combination of two disks, means for rapidly rotating the disks in opposite directions, studs on the adjacent faces of the disks, and an oscillation circuit connected to the disks.

2. In a wireless telegraph transmitter, the combination of two parallel disks, means for rapidly rotating the disks in opposite directions, studs on the adjacent faces of the disks, and an oscillation circuit connected to the disks.

'When the preliminary. statements were opened, it appeared that Marconi had alleged a date of invention later than Babcock’s filing date. Notice was given Marconi to show cause within a given time why a decision of priority should not be made in favor of Babcock on the record; and this time was on request therefor extended. No cause having been shown by the extended date, priority was awarded to Babcock, and there was no appeal therefrom. Patent issued to Babcock in execution of the decision on July 19, 1910.

The chief contention in the case is over claims 17 and 18, [290]*290which it is conceded by appellant are broader than those contained in the issue- of interference; but the latter, he contends, “are limited to, and cover nothing more than, specific and detail improvements common to both the Marconi and Babcock apparatus described in their respective later applications.” No question was made in the Patent Office that the re-issue application had sufficient foundation in the description of patent No. 935,381, or that it was in full compliance with the rules governing reissue.

The ground of rejection was that Marconi was estopped to make the broad claims of the application by reason of the former decision in the interference.

The reason given is that while the claims directly involved therein were narrower than those of the present application, these broader claims could readily have been made on the one involved, and priority determined therein, wherefore the right to them is concluded by that adjudication. In support of that view, Blackford v. Wilder, 28 App. D. C. 535, and other cases, are cited.

The question is whether the principle of res judicata has been correctly applied in refusing the reissue application.

The first contention of the appellant is that the parties to the proceedings are not the same, because the parties to the interference were Marconi and Babcock, while the present' controversy is between Marconi and the Patent Office. The distinction is one of form, and not of substance. The proceeding is ex parte. The Patent Office — the Commissioner of Patents— is net a party to the proceeding in the ordinary sense. He is the head of the office in which all applications for patents are filed. When filed in proper form, and fees paid, it is his duty to cause examinations to be made, and to issue the patent if “it shall appear that the claimant is justly entitled [thereto].” Rev. Stat. sec. 4893, U. S. Comp. Stat. 1901, p. 33S4. “It is the duty of the Commissioner of Patents, representing the public, and also the private rights of the inventor involved in the pending application, as well as all other inventors having the sanction of the Patent Office, to see that entire justice be [291]*291done to all concerned.” Re Drawbaugh, 9 App. D. C. 219-240. If, in the performance of his duty, the examination discloses a former patent anticipating or covering the invention applied for, the applicant is not justly entitled to a patent, and it is his duty to so decide.
