Opinion

Graham, Presiding Judge,

delivered the opinion of the court:

The appellee, Walter D. Walker, filed his application in the United States Patent Office on February 18, 1927, for a patent on improvements in composite photography. The substance of the claimed invention was a method of obtaining an image upon one photographic film, then superimposing an image carried by another photographic film upon the first film, and then photographing the images thus placed in such a manner that a composite image resulted, which composite image appeared to the observer to be the result of one photographic operation. The process will be more fully described hereinafter.

In response to suggestions made by the examiner, the specification and claims were variously amended on January 19, 1928, and on May 6, May 20, May 21, July 4, and July 8, 1929.

On February 7, 1927, the appellant filed his application for a patent covering the same subject matter, which went to patent on June 4, 1929. Thereupon the examiner suggested to the appellee the addition of claim 1 of said Pomeroy patent for purposes of interference, and by amendment such claim was added to appellee’s [1008] application. It constitutes the single count of the interference, and -is as follows:

The method of producing a composite photograph embodying two component parts, that includes making a transparent image of one component, making an image of the other component substantially uniformly opaque to light but reflective of light to show its image details, superposing the two images and illuminating the first image by transmitted light and the second mentioned image by reflected light, and exposing a fresh actinic surface to the first image and the second image so illuminated and superposed.

Thereafter the appellee moved to add to the interference claims 2, 3, and 4 of the Pomeroy patent, and a claim numbered 5, which was not copied from said patent. The appellee Walker moved to dissolve the interference on the ground that an inoperative method was disclosed in the Pomeroy patent. The appellant Pomeroy moved to dissolve the interference on the ground that the appellee Walker had no right to make the claim of the interference. The law examiner denied Walker’s motion to add counts 2, 3, 4, and 5, and his motion to dissolve the interference on the ground of in-operativeness. He also denied the motion by Pomeroy to dissolve the interference.

Both parties took testimony. The Examiner of Interferences awarded priority to Walker, the junior party and appellee. This decision was affirmed by the Board of Appeals. The principal point involved in the decision before the Board of Appeals was the contention made by the appellant Pomeroy that Walker had not made-such a disclosure in his original application as would justify a claim such as constitutes the count of the interference. The three tribunals in the Patent Office concurred in their holdings that Walker could make the count upon the disclosure he had so made.

The appellant brings the matter here, and waives any question of priority as it appears upon the record, resting his appeal entirely upon the ground that the Board of Appeals erred in deciding that the appellee Walker could make the count of the issue. This, therefore, is the only question now before us and the case will be determined on that issue.

A brief description of Walker’s method, as shown by his original disclosure, becomes necessary. The general purpose thereof is to produce a photographic image upon a film by ordinary photographic processes, which image usually consists of the scenery “ against which the actors are arranged to perform.” This film is transparent, and capable of transmitting light to illuminate the photographic images thereon.' The image to be superimposed upon the background is also a photographic image carried upon another film. The images carried upon this superimposed film are made opaque to transmitted light by the application of “ a coating of [1009] material 4, which is impervious to the passage of light, on the rear surface of the foreground film, #, and particularly over the image or images thereon.'1'1 (Italics not quoted.)

One film is then superimposed upon the other, the foreground film being the one upon which the image has been thus rendered impervious to transmitted light. A composite picture is then made of the images upon these films so placed, by means of an ordinary camera. The illumination of the films for this purpose is made by the use of, preferably, two sources of light, as shown by Figure 5 of the drawings. These sources of illumination are placed, one back of the films and having the said films interposed between this light and the lens of the camera, and the other in front of the foreground film and upon the same side as the camera. An alternative method of illumination is provided which consists of one light in front of the foreground film, and a mirror so arranged back of the background film that light will be reflected against the rear of the background film.

In his specification, Walker makes the following disclosures as to his method of illumination:

The method consists broadly in producing the background and foreground films as desired, and the superimposing of the latter upon the former in a manner permitting a positive or negative film to be produced from a single exposure; the image on the foreground film preferably having the rear surface thereof coated so as to render the image impervious to the passage of light whereby, by the proper control of light, the relative illumination of the foreground upon the background may be controlled. By means of this arrangement, the proper brilliancy of both the background and foreground is obtained.
* * ^ ❖ sjs ‡
* * * However, I preferably provide two sources of light 7 and 8, which may be suitably controlled, and which will properly illuminate the background and foreground films and provide the necessary brilliancy of the image on the foreground.

The first claim of the applicant’s original application is as follows:

1. The method of superimposing an image upon a background which comprises preparing the rear surface of the image to render it impervious to the passage of light, then placing the background and image together in proper relation and regulating the flow of light on both from different sources to obtain the proper illumination of each, and then photographing the same to provide a negative or positive of the picture thereby obtained.
