Opinion

Bland, Judge,

delivered the opinion of the court:

This is an appeal by the junior parties, Kliesrath and Sanford, hereinafter referred to as Kliesrath et al., or appellants, from the decision of the Board of Interference Examiners of the United States Patent Office awarding priority of invention to the senior party, Kes-ling, of counts 1 and 2 in an interference, proceeding which involved Kliesrath et al., patent No. 2,212,442, issued August 20, 1940, on an application, Serial No. 51,138, filed November 22, 1935, and Kesling’s reissue application, Serial No. 246,454, filed December 17, 1938, for the reissue of patent No. 2,069,526, which was granted February 2, 1937, upon an application filed July 20,1935.

The counts involved are claims taken from the Kliesrath et al. patent No. 2,212,442.

Count 1 is illustrative and reads:

1. The combination with a selective transmission mechanism having a plurality of spaced shifter bars movable longitudinally to establish different gear relations, of a shifter member movable into engagement with one or another of said bars, means operatively connected with said shifter means for so moving the same, means including a double-acting fluid pressure motor operatively connected [1010]*1010with said shifter member for moving the same together with the shifter bar selected thereby in opposite directions, means including valve mechanism for controlling’ and directing the flow of fluid power to said motor, means for controlling the operation of the first named means, and means for actuating the two last named means in order to control the energization of said motor and to actuate the first named means including a control lever movable laterally for actuating said first mentioned means and movable longitudinally for controlling said valve meohmism. [Italics ours.]

Both parties took testimony. The evidence of Kliesrath et al. was submitted for the purpose of establishing conception of the invention in 1931, reduction to practice in the summer of 1982, and continuing development work leading to “commercial exploitation of the invention” in 1934.

Kesling’s testimony was directed towards establishing completion of his invention as of the filing date of his parent application, Serial No. 683,977, filed on August 7, 1933, upon which application patent No. 2,034,400 was issued. This is the only date relied upon by Kesling and that he is entitled to this date is not here in controversy.

As will later herein appear, the invention involved and the issues •pertaining thereto are of such character as not to require a detailed description of the devices of the parties. It is sufficient to state that the invention relates to a mechanism for providing power to assist in the shifting of the gears of an automobile transmission. The device, generally speaking, and particularly with reference to the functions performed by it, is well understood in the art as being one which is designed to eliminate floor board and front seat space waste by placing the instrument which initiates the shifting of the gears to the dashboard rather than elsewhere. After the initial operation of the dashboard shifting mechanism has taken place the automatic auxiliary power device operates to shift the gears.

It is the contention of Kliesrath et al., that the record discloses that they have proven satisfactorily that they had successfully reduced to practice the invention defined by the counts as early as 1932 by the installation on a Dodge car owned by Harold W. Price of a device which completely responds to the counts involved. The date of this alleged reduction to practice being prior to any date to which Kesling is entitled, Kliesrath et al. argue that no further consideration need be given to other record facts.

It is also contended by Kliesrath et al. that if the view of the board as to their said earlier reduction to practice is accepted subsequent installations of a somewhat different device on other cars amounted to a reduction to practice in the event the counts are construed in accordance with appellants’ interpretation of their meaning.

A further contention is made by Kliesrath et al. that since it is admitted that the device installed on the Dodge car in 1932 fully [1011]*1011responds to the terms of the involved counts appellants must be given a conception date prior to 1932 and that the subsequent installations and other acts must be held to be proper evidence of dilligence during the critical period so as to give the first conceiver the award of priority even though the last to reduce to practice.

The facts are riot in serious dispute although there is considerable argument between the parties as to the effect to be given certain facts proven and spirited contentions with reference to the law applicable to such facts.

On the first question presented as to whether or not the earlier installation of the Kliesrath et al. device on the Dodge car amounted in law to reduction to practice the board summed up the facts and held, for reasons stated, that appellants had not proven a reduction to practice by the 1932 installation. It said:

Kliesrath and Sanford rely for priority on installations of gear shifting devices in several different cars. The first of these installations which allegedly constitutes a reduction to practice of the invention in issue was made in July 1932 on the Dodge car owned by Harold Price. It is not denied by the party Kesling that the Dodge installation was made in July 1932, nor that the device so installed responded to the requirements of the counts in issue. It is, however, strenuously urged (1) that the record does not show that the device so installed was the result of a joint conception of Kliesrath and Sanford and (2) that the device was not satisfactory and thus fails to establish a reduction to practice of the subject matter in issue.
The first contention seems to be based on the idea that the Dodge installation was the invention of Harold Price and was Aot the invention of Kliesrath and Sanford. This raises the question of third party inventorship. It was held in Tepas et al. v. Geldhof, 521 O. G. 523, 1940 C. D. 603, 27 C. C. P. A. 1265, 112 P. (2d) 800, that it is well-settled law that in an interference proceeding, a party cannot successfully contend that the invention is not that of his adversary, but that of a third party.
Several witnesses testified concerning the Dodge installation; from their testimony it is clear that the gear shifting arrangement did shift the gears but that this" was accomplished with a considerable clashing of gears. It also appears that the mechanism remained on the car for approximately two weeks during Which period it was on and off the car about 25 or 30 times for adjustment. After this it was taken olf the car and tested on the test bench. The nature of the bench tests is not given in any great detail and the results obtained therefrom are not stated.
The clashing of the gears is admittedly an unsatisfactory operating condition Which would likely result in damage to the mechanism; but it was stated that the Dodge normally shifted hard as it was not provided with synchronizing-means in the transmission.
We are of the opinion that the Dodge tests are inconclusive in establishing satisfactory operation of the device in issue.
