164 Opinion on Camera and Film Patent. claim is invalid. Hatch v. Moffitt (C. C.) 15 Fed. 252; Wooster v. Calhoun, 11 Blatchf., 215, Fed. Cas. No. 18,035; Excelsior Needle Co. v. Union Needle Co. (C. C.) 32 Fed., 221; Smith v. Nichols, 21 Wall, 112, 22 L. Ed., 5G6; Locomotive Works v. Medart, 158 U. S., 79, 15 Sup. Ct., 745, 39 L. Ed., 899. By the terms of the claim the length of the film is not defined, nor is the number of photographs which it is to represent defined. It is to be an unbroken transparent or translucent, tapelike, photographic film ; it is to have thereon equidistant photographs of successive positions of an object in motion; these photographs are to be arranged in a continuous, straight-line sequence; and the number of them is not limited, save by the length of the film. The film was not new, and if the other characteristics of the product are not new, or are new only in the sense that they add to the article merely a superiority of finish or a greater accuracy of detail, the claim is destitute of patentable novelty.

The substituted specification of that application contains this statement : "The sensitized surface is preferably in the form of a long tape, although it may be a cylindrical surface on which the photographs are taken in a spiral line;" and, in referring to the drawings, states that "3 indicates the transparent or translucent tape film, which before the apparatus is put in operation is all coiled on a reel," etc. In that application, for the first time, a claim was made for the product. After the claim, as originally phrased in that application, had been rejected by the i^atent office, it was amended by the applicant to read as follows : "(8) An unbroken transparent or translucent tape film, having thereon a continuous series of equidistant photographs of an object in motion, arranged in a single straight-line sequence, substantially as set forth." This claim was again rejected upon a reference to the Le
