205 F. 735 | 9th Cir. | 1913
The appellant, as the owner of reissue letters patent No. 12.297, granted to Robert Strain December 27, 1904,
The claims alleged to have been infringed are 1 and 10, which are as follows:
Claim 1:
“In a fruit grader; in combination a plurality of independent transversely adjustable rotating rollers, a nonmovable grooved guide lying parallel with the pla'ne which passes vertically and longitudinally through the center of said rollers, said rollers and guide forming a fruit runway, a rope in the groove in said guide, and means to move said rope.”
Claim 10:
“In a fruit-grading machine, a runway formed of two parallel members, one of said members consisting of a series of end to end rolls, brackets carrying the rolls, guides for the brackets, and means for- adjusting the brackets upon the guides, substantially as set forth.”
The defenses are invalidity of the claims, through anticipation of the combination thereby called for, and nonirifringement.
The issue can be more clearly and concisely explained by a reference to the state of the art when the patent was issued. There was at that time in practical use what was commonly known as the California grader, based upon a patent (No. 458,422) granted to J. T. Ish, August 25, 1891. The essential members of this device were (1) a long horizontal roller, with graduated sections or steps, turned down from a large diameter to a smaller one, resembling an inverted telescope; and (2) a flat endless belt, so adjusted that it was longitudinally parallel with the axis of, but a little lower than, and with a slight lateral inclination from the horizontal toward, the roller. The oranges were fed or delivered at a point near the large end of the roller, and by the moving belt were carried along, with one side resting upon the belt and the other upon the roller, until a point was reached where the space between the edge of the belt and the roller section was large enough to permit them to fall through into bins or receptacles • provided for thát purpose. It will be seen that thus the oranges of the smallest size were first eliminated, and then those a little larger, and so on; the largest being carried to the largest opening, which, of course, was opposite the smallest and last step. Inasmuch as the roller rotated upward and outward, the oranges could not be caught and squeezed, but were constantly turning' different sides to the opening between the roller and the belt, through which there was a tendency to escape as soon as a point was reached where the aperture was larger than the smallest diameter of the orange. Means were employed to give the belt rigidity, and not uncommonly a round belt or “rope” resting in a groove was used; but these were doubtless mechanical equivalents, and the variations in this respect are not thought to be of importance.
While efficient beyond any device theretofore invented and of great practical value, in actual use the Ish machine disclosed certain weak
In this state of the art Strain conceived the invention covered by the claims in suit. In effect it may be described as a modification of or addition to the Ish machine, by cutting the roller into as many pieces as there are steps, and separately mounting them, all in line longitudinally, each being independent and transversely adjustable. More accurately, several short rollers of uniform diameter are arranged in line, to take the place of the one long graduated roller of the Ish machine, and the required grading space in the case of each roller is secured by adjusting the roller toward or from the traveling belt. It is apparent that with such a construction the rollers may be so arranged as to form a true alignment, and the grading aperture thus be made of uniform width throughout the entire length of the runway, or they may be so adjusted that the opening has as many widths as there are rollers, or for half the distance it may be of one width and the other half another width, and so on. As a consequence, the
“It is not sufficient, to constitute an anticipation, that the devices relied upon might, by a process of modification, reorganization, or combination, be made to accomplish the function performed by the device of the patent.” Western Elec. Co. v. Home Tel. Co. (C. C.) 85 Fed. 649; Topliff v. Topliff, 145 U. S. 156, 12 Sup. Ct. 825, 36 L. Ed. 658; Gunn v. Bridgeport Brass Co. (C. C.) 148 Fed. 239; Ryan v. Newark Co. (C. C.) 96 Fed. 100; Simonds R. M. Co. v. Hathorn Mfg. Co. (C. C.) 90 Fed. 201-208; Gormully & J. Co. v. Stanley Cycle Co. (C. C.) 90 Fed. 279; Merrow v. Shoemaker (C. C.) 59 Fed. 120.
That this is a novel and patentable improvement is conceded by the plaintiff, but he contends that it is only an added element for an additional function, and that therefore it cannot operate as a warrant for the appropriation by the defendants of his patented invention; and this contention we think must be sustained. That every essential element of the Strain invention is found in defendants’ machine'cannot be questioned. So far as the sorting or separating of the fruit into desired sizes is concerned, precisely the same result is reached by the use of the same means operating in the same maimer. The truth of this proposition is strikingly illustrated in appellant’s brief by a cut of defendants’ machine as it appears with the guide arms eliminated and the several roller units brought into close proximity. In this form there is perfect equivalence, if not absolute identity. It exhibits the complete combination called for by the claims in suit without modification or addition, and the infringement is clear.
“The mere fact that there is an addition, or the mere fact that there is an omission, does not enable you to take the substance of the plaintiff’s*740 patent. The question is, not whether the addition is material, or whether the omission is material, but whether what has been taken is the substance of the invention.”
True, the plaintiff’s rights do not extend beyond the claims in suit, and are subject to the limitations thereof; but the language of these claims is not, as argued by the defendants, to receive a narrow, literal construction. While the invention is not basic or primary, it is substantial and important, and is therefore entitled to a fair range of equivalents. Continental Paper Bag Co. v. Eastern Paper Bag Co., 210 U. S. 405, 28 Sup. Ct. 748, 52 L. Ed. 1122.
For the reasons stated, the decree of the lower court is reversed, and the cause remanded, with instructions to grant the relief prayed for.
