American Tri-Ergon Corp. v. Coe, 30 F. Supp. 83, 43 U.S.P.Q. (BNA) 178, 1939 U.S. Dist. LEXIS 1941 (D.D.C. 1939).

Opinion

GOLDSBOROUGH, Justice.

For the .purposes of this opinion, the plaintiff will be called Vogt and the defendants, Radtke and Whitson.

This is an interference proceeding in which each of the indicated parties seek the grant-of-a patent because of priority of invention upon the following counts.

1. In sound reproducing apparatus, the combination of a photoelectric cell having an alkali cathode, means for illuminating the cell with acoustically-modulated light, and a circuit connected with said cell in which flows a correspondingly modulated current.

2. In sound reproducing apparatus, the combination' of a photoelectric cell having an alkali cathode, a constant source . of light, means' for uniformly progressing a film between said source and cell, said film carrying a photographic sound record of varying capacity, so that said cell is illuminated by acoustically-modulated light, which has passed through the film, and a circuit connected with said cell in which flows a correspondingly modulated current.

3. In sound'reproducing apparatus, the combination of a photoelectric cell having an alkali cathode, means for illuminating the cell with acoustically-modulated light, an amplifier, a circuit connecting said cell with said amplifier, a sound reproducing device, and a circuit connecting said amplifier with said sound reproducing device.

4. In sound reproducing apparatus, the combination of a photoelectric cell having án alkali cathode, means for illuminating the cell with acoustically-modulated light, an amplifier, a circuit connecting said cell with said amplifier, and a circuit connected with said amplifier, in which flows amplified currents which vary correspondingly with the variations of said acoustically-modulated light.

The Case of Radtke.

Radtke claims conception and disclosure on the 20th-of November, 1916 and introduced into evidence a circuit drawing of that date called the Leich drawing. He claims a complete reduction to practice in January 1917; also reduction to practice- in’ [85]*851918 and in November 1919, although the only satisfactory evidence of the so-called 1918 reduction to practice fixes the date as of September 1919. The Court specifically rules that it must be controlled by the September 1919 date. The Radtke application was actually filed on December 27, 1922. Each one of the four counts in issue contemplate reproduction of sound by acoustically-modulated light. The three alleged reductions to practice above mentioned all involve production of sound and not reproduction of sound, as contemplated by the issues in this case.

In a previous trial, Radtke stated that a so-called “Drum Heliophone”, which allegedly was the basic apparatus used in the November 1919 reduction to practice, had nothing to do with the reproduction of sound, but involved the amplification of heart beat sounds.

As regards the Leich drawing, it was not produced by Radtke at any of the Patent Office hearings, nor was it referred to by 'him in these hearings. Radtke stated that he made the drawing in November ,1916, put it..in a. magazine, laid it in. the .drawer of his desk, and ‘ inferentially lost sight of it. He stated that recently he was examining a bound volume of the indicated magazine and 'thát the drawing dropped out. Leich, who allegedly witnesses the drawing, is dead, and a stenographer was produced who stated that she had placed ■her initials under Leich’s name on a drawing at Radtke’s request, as a witness to .Leich’s signature, Radtke’s corroboration as to the drawing was not of a character which would justify a court in basing any conclusion upon it.

I think that the Court should say that Mrs. Phillips, the stenographer reférréd to, impressed the Court favorably-, but at the time of the alleged conception and drawing, she was employed in an adjoining office, was merely called in to witness Leich’s signature, knew nothing about the subject matter of the drawing, and had no scientific education; so that any identification of the drawing obviously could not be made by her.

The patent application of March 27, 1922, undoubtedly disclosed the counts at issue, but it is to be noted that on the 26th day of May, 1921, when Radtke sent his application to his attorney in Washington, the so-called British abridgements, which contained a description of the circuit described by Radtke in his application had been in a scientific library in Chicago, frequented by Radtke, since May 17th.

But even if the Court had been able to find a conception and disclosure in November 1916, and any' of his claimed reductions to practice, it would still be forced to hold that there was deliberate suppression and concealment on his part until May 26, 1921 when he sent his application to his attorney in Washington. Quoting from Radtke’s testimony from a point on page 1295, to a point on page 1298 of the record, Radtke testified as follows:

“Ttí'é' Court. Then, as I understand it, the sketch, of November 20,. 1916, corresponds in all the points indicated as the drum heliophone with its associated apparatus exhibited in 1919; is that right?
“The Witness. Yes, your Honor; and the Leich sketch showing .these elements in association that I have mentioned was present in the test made by me in January of 1917.
“The Court. What apparatus did- you have ,then?
“The Witness. I had the cigar machine with the circuit set up in accordance with the Carlson drawing which also had every one of these elements in combination, and I proved with that combination that I got an acoustically modulated beam of light which produced sound when I waved the strip record in the vision of’ the photo-electric cell.
“The Court. That, of course, is his conception of what he did, not a judicial conclusion.
“By 'Mr. Day:
“Q. Relatively , to that last answer, describe Figure 2 of Radtke Interference Exhibit. 8 and also tell what this Exhibit 8 is. Á. Radtke Exhibit 8 of the Interference record 63090 is the original sketch which I sent to the patent attorney, Boyden, here in Washington, in May of 1921, accompanied by a specification drawing for patent application; and in this sketch are •shown every one of the elements necessary for producing sound from an acoustically .modulated record. The light source is .hére (Indicating).
“The' Court. As I understand it, this drawing in 1921 which you sent to your .patent attorney-.in Washington, was no different in principle from the drawing you [86]*86made in' 1916, and that the drawing you made in 1916 would have been adequate if sent to your attorney in .Washington to justify an application for a patent, including the four counts involved in this issue. Is that what you say ? Is that what your testimony is?
“The Witness. Well, with the proper explanation with which I accompanied the specification; that.is, I would have to tell the patent attorney the interrelation of these pieces of apparatus,
“The Court. 'Well, from the drawing you made in 1916 could you have given him an explanation which would have been • sufficient-to justify an application containing the four counts at issue in this case ?
“The Witness. . Yes.
“The Court. Why didn’t you do it in 1916?
