This is an appeal from a judgment, dismissing the complaint in a patent infringement action because of the invalidity of the patent — No. 2,318,152. The primary object of the invention is to disclose “a cosmetic holder, all parts of which are wholly composed of plastic material”; and the mechanism disclosed was, in general, concededly old: that is to say: “a cosmetic holder in which the carrier for the cosmetic is advanced by the relative rotation of two slotted members.” However, no such holder had theretofore been made wholly of plastic; and hence the claims. It would serve no purpose verbally to describe the disclosure in detail, or that of Patent No. 2,104,902, issued to Morrison, on January 11, 1938, upon which the judge particularly relied to invalidate the patent in suit. The parallelism between the two cannot be satisfactorily shown without the figures; and we are obliged to assume a familiarity with these in our discussion. We shall consider the issue of validity in two aspects: (1) whether it was an invention to change from metal to plastic; (2) whether, if not, Gelardin’s modifications of Morrison’s disclosure can support his patent.
It has at times been said that a change in material can never of itself be invention; but, if that be taken as an absolute, it is not true. Invention is the act of putting together elements — all usually old —which gives them an added value; and the combination must be one for which exceptional imaginative talent is necessary. How exceptional this must be is another matter; but it would be as absurd to maintain that the substitution of a new material can never require originality, as that it could never make a profitable advance.1 We shall therefore assume that the change from metal to plastic might support the patent. The difficulty is that in the case at bar there is no reason to suspect that it did. Although metal had been always used in making such holders before the last war, by the end of 1940 it became plain that it would soon become unavailable. In the words of one of the plaintiff’s witnesses: "We eventually would completely lose metal.” Under the spur of this Gelardin set about finding a substitute, and began experimenting in plastics, in which he had been already a worker as he had been in metals. He testified that he completed his invention in about three months, and he filed his application during the following summer. The holder went into very wide sales, about 22,500,000 in five years; although that is not as significant as at first blush might appear, for 150,000,000 are sold every year. Furthermore, this success was limited to the war years and the year following; for the uncontradicted testimony was that by the autumn of 1946 the art had “all gone back to the metal case, to the extreme limit of the possibilities of securing them.” (sic) Let us then sum up the facts. The need had hardly arisen before it was supplied; there had been no history of earlier unsuccessful efforts; the art repudiated the change as soon as metal returned. Moreover, although there had never been an all plastic holder, there had been at least one partly made of plastic; and that material was already in use for kindred purposes. (Gelardin himself had been making flashlights of metal and plastic, apparently interchangeably.) There seems to us in all' of this not the least basis for inferring that plastic would not have occurred to any competent person, who was looking for a substitute for metal in such a holder. If the disclosure was patentable at all, it was because of the structural changes devised.
The second of these was a mere convenience in manufacture. It was much easier, when working in metal, to fabricate a flat sheet with a diagonal slot, and roll it into a cylinder to be inserted into a cylindrical outer casing, than to make a “relatively thick-walled outer sleeve” with “an internal helical groove.” When working in plastic, there are no manufacturing difficulties in moulding the helical groove on the inside of the “sleeve,” provided that be made thick enough. As to the first difference, we assume that we must take it that it would have been impossible, when working in plastic, to lock Morrison’s “guide tube, 4” to his “operating head, 5” by turning up 'its lower edge within the “head,” as Morrison disclosed. There is no contradiction of Hammer’s testimony that “the chances are that they” (the teeth) “would all break off.” Be it so, it does not seem to us possible that, if a worker in plastic found this to' be true when he followed Morrison’s disclosure, he would have been checked by his inability by some other means to lock together the “guide post, 4” and the “operating head, 5.” The very fact that he was dealing in plastic would suggest to him that the two members could' be moulded as one. The testimony upon this is uncontradicted. Gelardin himself conceded that it had been' known for “a good many years” that a moulder in plastic “could make in one piece what in metal required two pieces to be joined together.” And Brunhaber, Gelardin’s plastic fabricator, testified that if he were faced with a metal article “made in several pieces” which was to be reproduced in plastic, he would try to make it into “one piece, if it is possible”; for that was “one of the advantages of using plastic.” A priori, we cannot therefore regard the first of the two changes as demanding more than the common knowledge of the art.
Thus it appears that, once metal became scarce, resort to plastic was almost inevitable; and that once resort was had to plastic, the art needed nothing more to guide it than Morrison. Even so, a vast success might make plausible the case for invention; but here there was not any such
Judgment affirmed.
