(specially assigned). The patent in suit is for a so-called “visible'’ typewriter, in which the printing is at all times able to be seen by the operator, without stopping the work or
The defendants manufacture a typewriter which also has two-letter type bars, pivoted concentrically on a segmental frame, which is shifted vertically to bring the different characters to the printing point. The only distinction from the machine of the patent, taking it as it reads, consists of the “hitch up” between the key lever and type bars, which in the complainant’s machine is direct, both keyboard and type bars being carried on a pivoted frame or cradle, by the rocking of which, without breaking the connection, the shifting of the type-bar frame is brought about; while in the defendants’ machine the connection is bjr links, permitting the keyboard to remain stationary, the type-bar frame alone being moved.
The patent was issued to James D. Daugherty August 23, 1892, on an application filed March 8 of the same year; the invention going-back, as it is said, to some time in 1883. There are two claims relied on, as follows:
“37. In a typewriter, tbe combination, with, a series of individual pivoted type bars carrying two or more type, of a vertically-shifting frame for sustaining said bats and suitable means for shifting said frame to bring either of the type in proper position to make an impression.
“38. In a typewriter, the combination, with a series of type bars provided with two or more type, of a vertically-shifting frame for sustaining said type bars concentrically, a series of key levers connected with said type bars, and a series of keys for operating said levers.”
The only difference between these claims is that in the last the .type bars are concentrically sustained. Taking- them broadly as they read, they cover every machine in which, with the other elements involved, there is a vertical shifting of the type-bar frame; and according to this, without more, the defendants infringe. It is only as they are restricted to the particular character of structure specified in the patent in which this idea is utilized that they do not. It is on the construction, therefore, to be given to them, the patent being valid, that the case turns.
There is nothing to anticipate the patent, whatever 'its construction, in the prior art. With all the variety which there appears, there is no device to in any way correspond. The idea of visibility, no doubt, was not new. There was a crude attempt at it in the Horton, which was applied for as early as March, 1882, as well as in the Brooks of the same year, to say nothing of the Fitch (188G), the Prouty and Hynes (1887-
Nor can it be successfully maintained that it involved nothing patentable to transfer the shifting from the platen to the type-bar segment, or to change the 'direction to up and down. Invention has often been predicated upon less; and the highly beneficial results thereby secured fully justify its recognition here. It may not be entitled to any extended scope. Union Writing Machine Company v. Domestic Sewing Machine Company, 109 Fed. 85, 48 C. C. A. 244. It is not as though Daugherty originated the visible idea. That, by suggestion at least, was already in the art, although it must be conceded that he was the first to give it practical shape. And so, possibly, was the shifting of the type-bar segment, although that depends on how far the invention is able to be carried back. It is tied up also, to a certain extent, to the concrete expression of it which we have. And it may be doubtful whether the inventor had any conception of it outside of the rocking cradle, carrying keyboard and type bars, which he devised, except as in one of his patents he shifts the platen vertically instead. But, allowing all that is so said, there can be no question as to the novelty and inventive character of that for which the device, all tilings considered, is entitled to stand.
It is immaterial, in view of this, to inquire just when the invention was conceived, or at what date there was a reduction to practice, or whether due diligence was used, of which considerable evidence has been given, and which lias been extensively discussed. These are importará in interference proceedings, or where an issue as to priority between different inventors for the same invention is raised, but not where there is a mere comparison with other patents to determine the novelty of the device. Nor are the dates of the applications of alleged anticipating references of any account in such a case. A patent takes rank as a publication, negativing novelty, oulv when it comes out. Bates v. Coe, 98 U. S. 31, 25 L. Ed. 68; Diamond Drill Co. v. Kelly (C. C.) 120 Fed. 282; Eck v. Kutz (C. C.) 132 Fed. 758, 764. A mere
The first appearance of the invention in the Patent Office was by application filed November 15, 1889, which may thus be reg'arded as expressive of the original conception of it, of which those coming afielare merely variant forms. This was held by the examiner to have been anticipated by certain references, and not to be mechanically operative ; and, acquiescing in this view, on June 13, 1890, it was formally withdrawn. Having meantime perfected his ideas, and remedied what was wanting, the inventor, on May 2, 1890, filed a new application, which, after sundry rejections and amendments, was finally made the subject of interference proceedings, June 22, 1891, with the application of Arthur W. Street, as to two claims, which were held to be included in two of Street’s. Before this, however, on June 9, 1891, certain other claims which had been allowed were canceled and made the subject of a divisional application, on which a patent, No. 457,258, was granted August 4, 1891. There is no particular significance in this patent, except as it is a part of the history of the proceedings of the Patent Office, and except, also, as it disclaims the pivoted shifting frame carrying the type bars shown in the others. Neither is there, to the patent for an improvement on both of these, which was applied for September 1,1891, and granted July 12, 1892, as No, 478,925, save only that it provides for a vertical shifting of the platen, in place of the type bars. Meanwhile, in the interference proceedings, Daugherty, in his preliminary statement, having declared that he conceived the idea of shifting the type bars, instead of the carriage, as early as 1880, and his invention as a completed whole in the first part of 1885, while Street was only able to carry back his inventive conception to the spring of 1889, Street dropped out; and Daugherty, having gone on to a hearing and proved his contentions, was duly adjudged priority of invention January 21, 1892, and on March 15, 1892, patent No. 470,990 was issued to him accordingly. A week before this, on March 8, 1892, the patent in suit was applied for; and into this, by way of amendment, on June 23 following, claims 37 and 38, which are the subject of controversy were brought in; the patent issuing on August 23, two months afterwards. The question is as to the effect upon them, if any, of what had, preceded.
These two claims were taken from the interference proceedings, being the first two — with a slight modification — of the Street claims.
Street Claims.
1. In a typewriter, the combination with a series of individual pivoted type bars, carrying two or more type, of a vertically shifting frame for sustaining said bars, and suitable means for shifting said frame to bring either of the type bars in proper position to make an impression.
2. In a typewriter, the combination with a series of type bars, provided with two or more type, of a vertically shifting frame for sustaining said typo bars, and upon which said type bars arc pivoted concentrically, of a series of key levers connected with said type bars, and a series of keys for operating said levers.
Daugherty Claims.
2. In a typewriter, the combination of a frame and a carriage supported horizontally thereon in an elevated position, of a horizontal frame pivoted between its ends below the said carriage, and a series of type bars pivoted in the inner end of the said frame, having each two letters, whereby the tilting of the frame will move ihe type bars vertically and bring either letter in position to print, substantially as shown.
1. In a typewriter, the combination with a carriage of a vertically shifting frame carrying key levers and type bars, the latter having each two or more characters, whereby, when the frame is shifted, the type bars and keys are moved therewith, substantially as shown.
That the interference was rightly declared there can be no doubt. The broad claims of the one comprehending and conflicting as they did with the narrow claims of the other, both could not be separately maintained. And it is this conflict in transposed relation that continues here. The inventor, as it is said, having allowed the invention to be patented in the restricted form found in claims 1 and 2 of No. 470,990, cut himself off from any broad and comprehensive construction of it, such as is now set up. There can he no question that this ordinarily would he the result. It is contended, however, that, as the outcome of the interference proceedings, Daugherty became entitled to the claims there in controversy in all their breadth, and could have made them a part of his pending application, and, being entitled to write them into that, it is immaterial that he chose to write them upon the one he did; his right to do so being preserved by its having been put in before the other went out. That is to say, the claims having a place by right in either application, it was of no consequence as to which one it was exercised, a dedication or abandonment not being chargeable against him, because of his choosing the later one to come out. But that does not altogether state the case. There are other considerations which obtain. The question is not alone one of dedication or abandonment, but of having two patents for the same thing, as well, which, except under extraordinary circumstances, which are not found here, is not allowed.
It is a question, in the first place, whether these claims had rightly a place in either application, let alone both. The priority awarded to Daugherty in the interference proceedings did not necessarily so decide. The narrow claims found in the application for No. 470,990, of which, as against Street, he was found to be the original and first
Nor, looking into the specifications, is anything broad advanced. The inventor manifestly had a definite mechanical structure in mind, and that, and no more, is what he claimed to have devised. “The objects of my invention,” as he there declares, “are to connect the key levers and the type bars directly at their inner ends without the intervention of any other parts, so as to simplify and cheapen the construction and lessen the friction in.the operation of the machine; to separate the type bars and the key levers by means of division bars or plates, which prevent' the parts from interfering with each other; to provide each type bar with a type or types having capital and small letters or other characters upon them, and to change from one letter or character to the other by raising the inner end of the frame, which carries the type bars and the key levers, while the roller or platen carrying the paper remains stationary; to pivot at its rear end the guiding frame for the type bars, and which also holds or carries the ribbon, and to give to this guiding frame a vertical movement at its free front end, so that, while it serves as a guide to.the type bars, it also raises the ribbon, so that each type bar prints its character in alignment, and then, as the type bar drops back to its normal position, the guiding frame carrying the ribbon also drops, so as to leave each letter or character, as well as the whole line of writing, unobstructedly exposed to the operator without the movement of any other part; to operate the carriage by means of two pivoted, spring-actuated dogs, which allow the carriage to move forward one space each time that one of the type bars is operated, and which permit the carriage to slide freely back to its starting position.” The scope of the invention is thus made clear, and the means taken to accomplish it is amplified in the following text.
It is demonstrated, from what there appears, that, as already stated, the invention, so far as we are concerned with it, consisted substantially in mounting the type-bar series in a rocking cradle, arranged to carry both type bars and keyboard, by means of which the type bars were shifted vertically, according as one type or the other was to be brought to the printing point. And to this the inventor was tied. Not but that he was entitled to reasonable equivalents, but not to the extent of an entirely different structure. A rocking frame or cradle, carrying keyboard and type bars, and shifting the latter vertically, was of its es
Neither was there anything to justify their being brought into the patent in suit. As is expressly declared in the specifications, this patent was applied for as an improvement on the two which had gone before, No. 457,258 and No. 470,990; the object being “to improve, simplify, and cheapen the construction of the mechanism there described, in the manner and for the purposes set forth.” The particular improvements thereby introduced consisted largely in the special form of type-bar frame employed, which was composed of a block of metal, pivoted on the working frame or cradle by which it was shifted, and having vertical slots in which the type bars were set, to assist in guiding them to the printing point. “By the use of this block,” says the inventor, “I am enabled to mill slots therein for guiding the type bars accurately, so that they will at all times be guided to the printing point, * * * which makes these blocks interchangeable, so that a new one can be placed therein for an old worn one. This is a great improvement,” as he adds, “over the construction shown in the said patents, as the inner ends of the division plates, when depended upon to guide the type bars, are liable to become misplaced slightly, thus causing the type to stick in the guide, 22. So, also, owing to this rigidity of the inner end of the frame, 12, and the accurate guiding of the type bars thereby, the key levers may be supported independent of tlie shifting frame— that is, upon a rod, b', not connected with the shifting frame, 12, but supported by vertical ears, a', projeding from the base, A' — in which instance the said levers will simply turn slightly upon their pivoted point, 1)', when the frame is shifted.” The other improvements specified are of a like character, all going to minor features of the same general device to be found in previous patents, on which it is not necessary to enlarge.
Considerable stress is laid upon the fact that the key levers are not pivoted to the rocking frame or cradle by which the vertical shifting of the type bars is brought about. The distinction is even said to be radical, but is really of little account, not differing in substantive effect, from the alternative mechanism, which it supplants, as the inventor, upon cross-examination, is forced to admit. The key levers are mounted on the cradle and rock with it, under the action of the shift
Assuming, however, that this is not correct, and does not do justice to the inventor, it is nevertheless conclusive against any broad construction of the present patent that an earlier patent with equivalent narrow claims was allowed to come out, which result the co-pendency of the application for the second was powerless to avert. Not but that this may not sometimes be the case, but only that, under the circumstances, it was not so here. That the claims of the patent in controversy, upon any such reading of them as is contended for, are inclusive of claims 1 and 2 of No. 470,990, there can be no doubt. The only difference between the two sets is their breadth; the one being specific, where the other is not. It was on the strength of this idea that the interference was declared. The later patent thus became a second patenting of the first, which the law does not ordinarily allow. It is not enough that there was a difference in breadth of scope. Miller v. Eagle Manufacturing Company, 151 U. S. 186, 14 Sup. Ct. 310, 38 L. Ed. 121. An inventor may improve or narrow, but not extend. It is contended against this result that both applications were in the Patent Office together, by which the rights of the inventor were saved. It is no doubt true that, where an application in which an invention is expressed broadly is pending at the same time with one upon narrower lines, the' taking out of the latter does not preclude the subsequent allowance of the other in broader form. But that, unfortunately, is not this case. Both applications, of course, were pending together; but the one into which the broad claims were eventually brought was the specific and not the generic form, coming in apparently as an afterthought, when the other was already three months out. The interference proceedings having been disposed of on January 21, 1892, there was nothing to prevent the Street claims being made a part of the earlier patent, and, if the inventor was entitled to them, that was the place where it should have been done.
A reissue is ordinarily the only remedy where a patent is found not to be expressive of an invention to its full breadth. An enlargement
The question, on the other hand, is squarely decided by the Commissioner of Patents in Jones v. Larter, 92 O. G. 383, where it was held that broad claims inserted in a later application, after a patent had issued on a co-pending earlier one, could not be allowed. “The presumption of dedication to the public by disclosure in a patent,” as it is said by the learned Commissioner, “may, it is true, under certain circumstances, be overcome by having a concurrently pending application claiming it; but I know of no authority for holding that it is overcome by an application which does not and was not intended to claim it, merely because the claims are inserted therein long after the patent on the other case issues. In the present case Tarter could have made the claims of the issue at any time in his original case, and his failure to do so was, according to’ his own statement, due merely to a mistake as to his right to such claims. This was clearly a case where the claims could only be .properly made by reissue, if at all, and this was the view that Tarter took of the matter. He apparently did not think of inserting them in this case until six months after his patent issued, and inserted them then only upon the suggestion of the examiner. It was an error on the part of the examiner to make the suggestion, since to grant the claims in this case would be in effect to grant a reissue of Darter’s previous patent with broader claims, and at the same-time extend its term.”
The present case is not to be distinguished from Morse Chain Co. v. Link Belt Machine Co., 164 Fed. 331, 90 C. C. A. 650. In that case there were two applications co-pending in the Patent Office for over two
To the same effect, also, is Otis Elevator Co. v. Portland Co., 127 Fed. 557, 62 C. C. A. 339, where a similar attempt to have the claims of a later patent read broadly, as being generic, in the face of the restricted claims of an earlier patent, the applications for the second being co-pending, was refused, upon substantially the same grounds. The truth is that there is no particular saving grace in co-pendency, independent and apart from other things. Otherwise, the fifing of an application for a mere improvement, as here, before the earlier patent comes out, would allow anything to be brought into such application, by way of new and enlarged claims, that experience in the practice of the invention might suggest, which surely is not the law. Without enlarging upon the subject further, therefore, I am constrained to hold that, if the claims relied on in the patent in suit are to be so construed as to embrace the defendants’ machine, they conflict with and are anticipated by patent No. 470,990, previously taken out by the same inventor, and are void. It-is only by confining them to the particular character of structure described in the specifications, constituting an improvement, and not an enlargement, upon the earlier patent, that they can be saved. And upon this the defendants do not infringe.
It is also urged that the invention was covered by a British patent to the same inventor taken out in 1891, which ran out by the expiration of its term August 4, 1905, and that this, by Rev. St. § 4887 (U. S. Comp. St. 1901, p. 3382), having become the term of the patent in suit, it had thus expired before the bill was filed. The claims of the British patent were made up from those of No. 457,258 and No. 470,n 990, mentioned above, some being taken from each, from which the substantial identity of the invention as so patented with that of the two claims of the patent in suit, if construed broadly, would seem to ensue; the greater including the less. But I am on record as holding, in Hennebique Construction Company v. Myers (C. C. A.) 172 Fed. 869, that there was a complete doing away with the interdependence of foreign arid domestic patents by the industrial treaty of Brussels of 1900, which treaty was self-executing, and applied to existing patents, and would therefore be effective here. While my opinion was not the opin
Limiting, then, the construction of the claims relied on, for the reasons given, to a shifting of the type-bar frame by the mechanical means specified in the patent, the defendants’ machine does not infringe; or enlarging them beyond this, so that it does, the claims are void for double patenting. Either conclusion is fatal to the right to recover, and the bill must therefore be dismissed, with costs.
In each oí these references the first (late is the year when the patent was applied for, and the second, when it was granted, although, as we shall presently see, the last only, Is of any account. Where but one is given, the application and the issue were the same year.
