235 F. 290 | 2d Cir. | 1916
The contentious history of this patent is not all contained in reported decisions. There was a lengthy interference in the Patent Office, and Thropp there swore (the point being already vital) that his inventive date was February 1, 1905. Decision in the Fisk Case found proof beyond reasonable doubt of a commercial use in January, 1905. The contention here, and in the court below, is that in January, 1904, Thropp made and used an apparatus upon which claims 1 and 2 will read, so that as to those claims at all events the anticipation is overthrown. With great assistance from Judge Hand’s careful summary of evidence, we have gone over the testimony relating to the (so-called)
Giving the “Goodrich use” the scope and importance accorded to it in the First Circuit renders it necessary for plaintiff either to carry back his date of invention or assert that prior decisions have erroneously interpreted the patent and misunderstood the inventive concept. As above indicated, both efforts have been made. To carry the inventive date back of February 1, 1905, necessarily involves an admission of error (to say the least) on the part of Thropp when he took the interference oath. There is no legal bar to plaintiff’s making the effort. It cannot be held that Thropp’s oath constitutes an estoppel against what is now sought to be done; but inasmuch as the present effort mainly rests upon the testimony of the same witness, who once gave his date of invention as February 1, 1905, plaintiff cannot complain if evidence contradicting or varying that solemn statement is viewed with a critical eye, and strong corroboration demanded therefor.
In our opinion the patentee has never sworn that what he did in 1904 was the same thing that both he and Goodrich did in 1905. This is well shown by the form of question put to Thropp in the Fisk Case as compared with the corresponding question herein. When the patent was rested on February 1, 1905, as the inventive date, Thropp was asked “When did you conceive the invention set forth in” claims 1 and 2? And he gave in reply the date sworn to in interference. In this suit counsel inquired of Mr. Thropp, not when he conceived his invention, but “when [he] first conceived an open mold having the elements of claims 1 and 2,” and he replied, “In January, 1904.” Thus is it indicated that Thropp himself believed his invention to date from 1905 until he had been taught to confine that invention, not to what he thought it was when he first testified, but to what his counsel deemed it to be, after unsuccessfully encountering the “Goodrich use.”
This reduces the case to one inquiry, What was Thropp’s invention as disclosed by the specification? for it is from that (with such light a^ drawings may throw upon it) that we must ascertain in what the al
The device described in the specification consists substantially in a mold which presses into shape the clencher edges of a rubber motor tire, plus tape wrapping and filling pieces, surrounding both clencher mold and the portion of the tire projecting therefrom, all for the purpose of holding the whole tire “in position during the vulcanizing process.” This support is necessary, and what Thropp avoids, and presumably improved upon (in and by this patent), is the, use of closed molds through and by which heat was applied to the whole tire. His small mold forming the clencher edge, when wrapped in the tape which supported the rest of the tire, is subjected, not to a closed hot mold, but to live steam. The result of the operation is known as the “wrapped-tread” tire.
The patentee never conceived‘a wrapped-tread tire, or the apparatus for or method of producing one, until 1905, and he therefore never reached the inventive thought of his specification until that date; but it is now asserted (and will be here assumed for purposes of discussion) that in 1904 he made and attempted to use so much of his “tire-forming apparatus” as is necessary to mould the clencher edge or bead. It so happens that the two claims in suit will read upon the clencher bead-making mold, because from those two claims all reference to the rest of Throop’s “tire-forming apparatus” is omitted.
But in 1904 Thropp was not endeavoring to make a wrapped-tread tire, nor to do without the closed hot molds, to dispense with which is the very object of the apparatus covered by this patent; he used (at the most) the same kind of molds for forming his clencher beads in 1904 that in 1905 he utilized for his wrapped-tread tire; but he vulcanized by molds only, and not" by open or hot steam heat. He admits that the effort was not a success, and it is obvious that this discarded experiment has found its only utility in this endeavor to reinterpret the patent after its first defeat.
The invention disclosed by the specification is for an apparatus suitable for vulcanizing, not half a tire, but' a whole tire, not by two steps, but by one. The “Goodrich use” must be met by testimony at least as persuasive as that establishing it. It cannot be overthrown, either by an unsuccessful experiment, or by anything short of a “conception of invention consisting in the complete performance of the mental part of the inventive act.” Robinson on Patents, § 376. An anticipation must always be as broad as the invention, and the best that can be said for the contention here made is, not that any such broad conception enter
The invention in this case is single; if the claim does not cover the whole of it, so much the worse for the claim. The conception of invention dates from January, 1905, and belongs to the Goodrich Company. Invention is an idea; the quest for its origin is a search for the whole idea, not half of it. Thropp got his whole in 1905, a month after his anticipator.
Decree affirmed, with costs.
Claim 1 is as follows:
“1. Tiro-forming apparatus comprising an annular core or mandrel, annular pressure-rings arranged to engage the clencher edges of the tire leaving the outer body portion of the tire exposed and means for forcing the pressure-rings into a predetermined position with respect to the core or mandrel.”
