Morse Chain Co. v. Link Belt Co.
Opinion of the Court
In this suit the complainant should succeed I believe on every point raised except one, though that is unfortunately for him fatal to his success. This objection is that the reissue is not for “the same invention” as the original patent.
The only possible question, therefore, is whether there is enough indication in the patent itself to show that Morse was trying, though unsuccessfully, to express the idea of a pintle of more than two parts. If so, then the invention thus partially and imperfectly described became fully described in the reissue and there was no departure. However, unless that idea is to be found somewhere in the original patent, I cannot say that the reissue, which is clearly broader, is for the same invention as the original. Now, the fact is that the original patent was singularly express in its limitation to pintles of two parts. At the very outset the patentee so characterizes his invention, when he says:
“This invention relates to an improvement in driving chains for general power transmission and particularly to chains of this class, wherein the pin-tle consists of two parts bearing upon one another throughout their length.”
There is throughout the specification no indefiniteness of expression, but the pintle is referred to uniformly as a two-part pintle just as it is shown in the drawings. It is only in the claims that the least suggestion of ambiguity can be found!. Claims 1, 2, 3, 10, and 11 refer to pintles “formed of separate parts,” and this might be thought to give color to the contention that the invention covered was for a pintle of more than two parts. However, the context of the phrase, “pintles formed in separate parts,” in claims 1, 2, 3, and il, remove any possible ambiguity, and show that in those cases at least the patentee has
“Of which one part engages with the plates of one link only and bears upon the other part of the pintle.”
The contrast between the words, “one part” and the “other part,” particularly as the two parts bear upon each other, shows that only two could have been intended. In claims 2 and 3 the words are, “Pintles formed in separate parts adapted! to turn one upon the other,” and later on they are spoken of as “both parts of the pintles.” Claim 11 closes with the words, “one part of each pintle and to allow free movement of the other part thereof.” It is therefore apparent that the phrase “formed in separate parts” was not used by the patentee as signifying more than two parts unless it were in claim 10; nor has Morse ever asserted the contrary.
The history of this claim will show whether by it Morse intended something different by the same words, i. e., to include more than two parts in his pintle. Originally the specifications were followed by eight claims, each specifically referring to a pintle of two parts. Some 17 months later claims 9 and 10 were added!, also specifying two-part pin-tles. The action of April 28,1903, proves, if such proof indeed be necessary, that a two-part pintle was all that was in any one’s mind in regard to claims 9 and 10.
On February 18, 1904, claims 9 andl 10 were amended and claim 11 added. Claim 10 appears as a “pintle formed in separate parts.” In spite of the context it might be thought that to keep the phrase “two parts” in claim 9, and to change it in claim 10, indicated a change of intention, but the use of the same phrase, “pintle formed in separate parts,” in claim 11, disproves any such inference, because its context there proves that it meant only a two-part pintle. Moreover, the letter accompanying these claims proves conclusively that the patentee considered only “pintles formed in two parts” (see the first paragraph on page 235 of the defendant’s record).
To complete the proof, the patentee on March 17, 1904, amended! claims 1, 2, and 3, so- that the words “pintles formed in separate parts” replaced “two-part” pintles, but obviously without the least change of meaning. The upshot of the whole of this is that it is clear beyond any reasonable doubt that the patent pássed through the office and issued without the least intimation of the pintle’s being in more than two parts and with the clearest possible limitation of the patent to a two-part pintle.
Morse did then succeed in describing the species, two-part, of the genus, extended-bearing pintles,' and only that. In so doing he necessarily disclosed the elements, which made up the genus, since the species includes all the elements of the genus, but he gave no suggestion that he had conceived of those elements separately, or that he meant to claim them as an invention. Now he does conceive of them separately and claim them. It is true that, when the original claims are too broad, a reissue is good which narrows them. Edison v. Mutoscope Co., 151 Fed. 767, 81 C. C. A. 391. Strictly and literally speaking, that, of course also changes the invention so that it is not “the same,” but there
In the case of Thomson-Houston Elec. Co. v. Black River Transportation Co., 135 Fed. 759, 68 C. C. A. 461, the Circuit Court of Appeals for this circuit upheld! a reissue which omitted one of the elements of the combination disclosed and impliedly claimed in the original. Whatever may be said as to the facts, it is quite clear that the court had no intention of holding that this could be done when the original showed no signs of disclosing the invention actually patented. At the top of page 766 of 135 Fed., and on pages 467, 468, of 68 C. C. A., Judge Wallace says:
“The patentee not only described the same invention as is described in the reissue (with an amplification now omitted as to the details of construction and arrangement of the tension device), but also endeavored to claim the combination now claimed.”
Again on the same page he says that the commissioner may allow a reissue “by permitting a change in the phraseology for the purpose of defining more perfectly what was described and! claimed in the original.” None of this language is fairly applicable to the case at bar, if it be conceded, as I have tried, to show, that the original had no suggestion of anything but a two-part pintle.
This would make only obiter the consideration of the other points raised. The invention was a meritorious one, and the inventor deserved better fortune than so far he has got. Unfortunately the law is the law, and no judge has the right to stretch it in a hard case. I shall therefore be obliged to dismiss the bill for want of equity, with costs.
