Opinion

JACKSON, Judge.

This is an appeal in an interference proceeding from a decision of the Board of Interference Examiners of the United States Patent Office awarding priority of invention of the subject matter embraced in 7 counts to appellee.

The interference involves a patent of appellant entitled “Charge Forming Device,” No. 2,225,261, issued December 17, 1940, on an application, serial No. 15,201, filed April 8, 1935; and an application of appellee entitled “For Carburetor,” serial No. 212,738, filed June 9, 1938, as a continuation-in-part of an application, serial No. 435,394, filed March 13, 1930, which ripened into a patent, No. 2,365,910, dated December 26, 1944.

The patent of appellant is assigned to General Motors Corporation of Detroit, Michigan, and the Bendix Products Corporation of South Bend, Indiana, is the assignee of appellee.

The interference relates to an apparatus designed to facilitate the starting of a combustion engine when it is cold by providing for a desired ratio mixture of air and fuel. The mixture, richer in gas for cold starting, is gradually reduced to a leaner mixture of fuel content as the engine warms up. The article defined by the counts is connected to a carburetor to control the fuel mixture through automatic means. In ordinary parlance the device might be known as an automatic “choke.”

Count 6 is illustrative of the subject matter and reads as follows: “6. Means for controlling the fuel to air ratio of the fuel mixture supplied to an internal combustion engine during starting, warming up and normal operating conditions comprising a charge forming device having in combination, a fuel valve movable to different positions to vary the fuel mixture ratio, a throttle valve for controlling the quantity of mixture supplied to the engine, and means for changing the position of said fuel valve in accordance with changes in the temperature under which the engine operates, in accordance with changes in the intake suction of the engine brought about by changes in the engine speed and by changes in the position of the throttle valve.”

The counts originated as claims in the patent of appellant, the junior party, upon whom devolves the burden of proving priority of invention by a preponderance of the evidence.

Both parties filed preliminary statements. In that of appellant it is alleged that the invention was first disclosed to others and the exercise of reasonable diligence in adapting and perfecting the invention was begun on or about April 1, 1927; first drawing of the invention’ is alleged to have been made October 1,. 1927; reduction to practice on or about October 15, 1927; and first written description on or about August 1, 1930.

The preliminary statement of appellee alleges first drawing of the invention defined by counts 1, 2, 3, 6, and 7, disclosure of it to others, and the exercise of reasonable diligence in adapting and perfect» *266 ing the invention sometime during July or August, 1929; a written description thereof as defined by those counts and a reduction to practice during August or September, 1929. With respect to counts 4 and 5 it is alleged that appellee made drawings of the invention defined by those counts, disclosure of the invention to others and the exercise of reasonable diligence during September or October, 1929; reduction to practice as defined by those counts during ■October or November of that year; and a written description during December, 1929.

During the motion period appellee moved to dissolve the interference on the ground that appellant was estopped to contest priority because of his failure to request an interference on the involved subject matter with several prior interferences in which it had been involved with appellee’s parent application, serial No. 435,394. The Examiner of Interferences vacated the motion stating that the matter raised therein would be considered at the final hearing.

Appellant also moved to dissolve the interference on the ground that appellee had no right to make the counts for the reason that the device disclosed by him is inoperative. That motion was denied.

As originally declared, the interference involved two counts and upon appellee’s motion, the other 5 counts here involved were added and the interference redeclared.

Appellant took testimony. Appellee took no testimony but relied upon his filing date of March 13, 1930. Both parties filed briefs and were represented at the final hearing.

It appears that at the time of taking testimony appellant was an engineer in the employ of the Delco-Remy Division of General Motors Corporation and had been so employed since 1932. Immediately prior to that employment he and his father operated an experimental laboratory from 1930 until the death of the father in 1933. Prior to 1930 appellant was associated with the Dole Valve Company of Chicago.

It appears from the testimony that appellant and his father had developed a number of devices for manufacture by the Dole Company. Neither of them were employed by that company but had contracts with it, some on a profit sharing basis and others on a royalty basis.

Their experimental work with the Dole Company involved many different things, among which were temperature control devices for use on automobiles and automatic chokes for carburetors. Several structural developments for the latter are relied upon by appellant to establish priority of invention. One of those devices was installed on a Buick automobile in August, 1927. At the time of the taking of testimony that device could not be found, but a substantial duplicate of it was constructed for the purposes of the present interference and that duplicate is in evidence.

The device, as installed on the Buick, was described by appellant and three witnesses testified on his behalf with respect to its installation and operation. One of those witnesses had installed the device but it does not appear that he knew anything about its internal structure. Another witness, wife of appellant, likewise knew nothing about the structure of the device and, therefore, neither witness was competent to corroborate the testimony of appellant with respect to the operation of a structure which corresponds to that defined in the involved counts.

A reading of the counts clearly demonstrates that the construction of the device could be told only by those who had a knowledge of its internal parts. All that can be derived from the testimony of those two witnesses is that they had ridden in or driven the car in which the manual choke had been disconnected, and that the car operated successfully.

The third corroborating witness was well qualified in the art of automobile engine construction and operation. He had known both of the Jorgensens for a long period of time and had discussed with appellant the idea of eliminating a manually operated choke on an automobile. Those discussions, the witness said, were in detail and such a device was shown to him by appellant.

*267 The testimony of that witness was given 16 years after those discussions and, up to a certain point hereinafter referred to, was entirely from his recollection. No contemporaneous written document is in evidence, nor is the device itself.
