234 F. 657 | E.D. Pa. | 1916
Due to the interesting subject-matter of this controversy, or to its admirable presentation by counsel, or doubtless to both, it is with a feeling almost of regret that we accept the compulsion to tal<e the excluding view of it which we have taken. The case in its formal features is the ordinary one of the claim of a proprietary right in a product based upon the issue of letters patent and a denial of their validity. The patent bears the number 727,505, was issued for the claimed invention of Frederick John Warren, and now belongs to the plaintiff by assignment. The invention is based upon the discovery or recognition of a fact which, however familiar it may be to the initiated, seems so startling to the uninformed mind that there is a hesitation in its statement for fear of misconception. The fact, however, as we understand it, is this: If a delimited space be occupied, as nearly as may he, by broken material of a uniform unit
In considering anticipation defenses (prior use or prior invention) we start with the presumption that the patentee is the first inventor. This must be overcome, and by that measure of proof which the law requires. The effect given to prior use, prior invention, prior publication, prior patents, is based upon essentially the same thought- — the denial of the claimed invention. There are two thoughts in the statutory meaning of invention. One is the idea of originality, either of discovery or of creation; the other, the idea of priority or of novelty.
The practice of the art of road making was limited to a mixture of pitch and sand or fine stone, the small units of which were of a uniform'size. Without thought or intention on the part of any one, stone material of varying sizes had been dumped in some place, together with some pitch. The mixture happened to be in such proportions of stone of different sizes and of pitch as that the result was the same as the material of the present bitulithic road. Subsequently some one discovered the present method of producing this material, and was awarded a patent on his product. If the first dump heap was found, would its existence defeat the patent as an anticipation? Would it make any difference if the dump heap further happened to be within the limits of a road? Between these two extremes is to be found the line which separates what is from what is not an anticipation. An-
If the plaintiff was relying upon a process and not a product claim, the defense of noninfringement would be hard to meet. As against a product claim the defense is as hard to allow without a denial of all right in the plaintiff. The differentiation which the state highway officials make is impressive at first blush, but, to use a colloquial expression, “gets us nowhere,” because its statement of the different modes of road construction is no denial of the further statement that the product of the third may be an infringement of a product patent owned by the users of the first.
If it were not for the adjudications referred to, we might readily yield to the persuasiveness of the very able counsel for defendant, and be convinced by the forceful argument addressed to us, but we have not been able to see how we can follow him without refusing to follow the courts by which this patent has been held valid. For this reason the bill of the plaintiff is sustained, and the usual form of decree in favor of the plaintiff, with costs, may be submitted.
