Opinion

DICKINSON, District Judge.

This controversy concerns letters patent No. 707,934, issued 1o Woodville Latham. This is at least the third attempt to have the validity of this patent determined. It is -one generally known as the Latham loop patent. The controversy went off in the Independent Case, 200 Fed. 411, 118 C. C. A. 563, on the question of whether the patent concerned cameras or projecting machines, and in the Motion Picture Patents Co. v. Universal Co. Case on a question of license. There is no escape from meeting, in the present case, the question of validity. The fact of infringement is squarely admitted. The only claim in issue is the seventh. It is [725]*725asked that a narrow reading only be given to it, so as to cover a specific construction, the inventive merit of which is claimed to be in the fact that it is the result of a novel combination producing a new and useful result, every element in which combination is admitted (at least arguendo) to be old. It is evident that nothing short of identity in construction would demand an admission of infringement. We have the admission none the less. There is no charge or intimation of any ulterior purpose in thus sharply defining the issue, or in this absence of the disposition usually manifested by defendants to wriggle away from a successful charge of infringement. This may be due wholly to the confidence of the defendant in its averment of invalidity. We so interpret what would otherwise be a very accommodating attitude on jhe part of the defendant.

The defense of invalidity is based upon the proposition that every element of invention has been eliminated from the plaintiffs device, except that which is claimed to reside in the bringing together of features of construction in a combination involving invention. The problem thus presented to the constructor, as is asserted by the defense, is, however, wholly a problem in mechanics, involving no invention, but making its call solely upon the mechanical skill of the designer. It is further asserted to be the fact that the construction in which invention is claimed to reside was the actual production of the skilled mechanic, who was called by Latham fi> his assistance. What Latham did, it is asserted, was to give to the mechanic the idea of the construction which he wished to have made, and it was constructed for him. Had there been novelty in any of the features to be thus incorporated in the construction, or any novelty in the idea of having the several features in combination, invention would be conceded. When, however, all Latham did was to direct the mechanic to put the described device together, and ihe only call made upon the mechanic was'’to select from .the storehouse of his mechanical art what was required for the purpose and to make of the construction “a good and workmanlike” job, Latham cannot take out a valid patent covering the particular construction so put together, because (1) there is a total absence of invention, and (2) if there was invention in the mode of construction, it was not the invention of Latham.

Denial of the validity of such a patent is further based upon the averment that the claim to patent of this narrow scope was an afterthought not in the mind of the applicant, but originated with a patent solicitor long after the application was made and after the applicant had assigned his rights to the predecessor of the present plaintiff. The basis of this averment is that the application was filed June 1, 1896, and allowance of this narrow claim not made until August 26, 1902. In the meantime, an interference had blocked the allowance of the claims which incorporated the invention which the applicant thought he had made. The proceedings in the Patent Office resulted adversely to the applicant. This emasculated the application and left the device of the applicant devoid of every element of invention. The solicitor of the assignee of the applicant then amended the claims by inserting the one now in issue, and secured the allowance of it, and the issue of a patent limited to the specific construction described.

[726]*726The thought behind this defense would compel ready acceptance, except for several facts with which we are confronted, and the significance which is usually imputed to them. In the first place, we have the fact of original construction. The patentee is not asking for much when he asks to have his claimed proprietary right to this specific construction protected. Again, he has the prima facie right imputable to the grant of letters patent. The findings of the examiners .in the case of an application which has received real consideration of its claims, particularly if the findings be such as make demands upon the knowledge possessed by experts or those who have technical knowledge, command respect, and may well be accepted as persuasive. Still again, the juridical history of this patent may be thought to carry the implication that its validity has received judicial recognition in fact, although not made in form the subject of a judicial finding. . Still yet again, the persistency with which this device has held its place in a rapidly developing art, offering large rewards to any one who had a good substitute to offer, loudly proclaims its worth and value. Whatever impression is made upon the mind by the averments that the device is the product of another than the patentee, and that .the making of the claim in issue was an afterthought, is sought to be removed by a denial of their truth.

Thé fact issues thus raised will be later discussed, but on the whole the showing made by this plaintiff might well support a finding that the prima facie right arising out of the patent had not been overcome; This might well be, .or, with the trial judge at least, was, the impression first received. After an analysis of this presentation of the plaintiff’s case, this firs,t impression» wholly disappears, or .is at least dimmed beyond the point of recognition of its presence. This second thought comes with even the most hasty glance over the disclosures of the prior art. Edison is the acknowledged father of the motion picture art. His camera and his means of getting upon the film the pictures to be projected upon the screen are still its basis and its backbone, and no essential advance has been made upon his contribution to the art. He fully and finally met all the conditions of the problem with which he was confronted. c -

The problem which Ratham had before him, and which he supposed he was meeting on virgin ground, presented one condition of difficulty with which Edison was not confronted. This arose out of the increased length of the film. Edison had to do with film rolls from which the film could be directly fed to a position in front of the camera, and kept there for the required interval of time. The inertia and momentum of heavy reels made this ■ impracticable. Latham though he was the first to meet this difficulty by having the supply reel deliver the film, not directly to the feeding mechanism, which carried it to and held it before the window, but delivered it through the medium of an excess of supply which formed a loop, and to have the feeding mechanism get the film from the slack of this loop. In this way all tug upon the supply reel was avoided. A resort to the same method prevented the intake reel from tugging at the film. This and one other feature, of which we next speak, constituted the whole [727]*727of the advance upon the prior art, which Ratham proposed to himself.

We are, of course, for the present, ignoring the claim of the patent now in issue.
