117 F. 845 | U.S. Circuit Court for the District of Eastern Pennsylvania | 1902
This patent has been the subject of marked vicissitude. It was at first sustained by Judge Dallas in’ this court in Hanifen v. E. H. Godshalk Co. (C. C.) 78 Fed. 811, but upon a rehearing, on account of certain expert evidence, by which he felt himself controlled, he decided against it. On appeal, however, he was reversed, and the patent upheld, although the court of appeals was not unanimous, Judge Butler dissenting from the views of Judge Shiras and Judge Acheson, who constituted the majority 28 C. C. A. 507, 84 Fed. 649. It came up again before Judge Gray in Hanifen v. Lupton (C. C.) 95 Fed. 465, where the validity of the patent was conceded, the suit being defended on other grounds. It next appeared in the Second circuit, and was sustained by Judge Townsend in a well-considered opinion (Hanifen v. Price [C. C.] 96 Fed. 435); but he in turn was reversed by the court of appeals
The patent was issued in 1887 to Eevi Bywater, and, according to the second claim which is the one in controversy, the invention is declared to be “a knitted fabric, composed of face and back yarns of different materials, the face yarn being looped at regular intervals and on alternate stitches of adjacent rows of the back yarn, and being matted and curly, and having a smooth back, whereby the said fabric has the appearance of looped or Astrakhan cloth as described.”
In the specifications which precede, the invention is said to consist of “a new and improved textile fabric having the face yarn thereof looped on the stitches of the back yarn; * * * the said face, which is formed of mohair, worsted, or other yarn, being beat up so as to present a wavy or curly surface, and the back, which is formed of woolen or other yarn, brushed so as to present a smooth surface, the fabric having the appearance of looped or Astrakhan .cloth.” In carrying out his invention the patentee declares that he employs a circular knitting machine, a partial description of which he gives, and in the operation of knitting the fabric he says that the thread by which the rough face or Astrakhan effect is produced is so placed upon the needles by the backing wheels as to be alternately in front of and behind two needles, the backing wheels being so set in a four-feeder machine that for successive rows of the fabric they alternately press back different needles, thus forming the loops on alternate stitches of adjacent rows. It will be thus seen that the patent is distinctly for a textile fabric of specific character and designated structure. It is not for the process by which it is made, nor the machine for making it, each of which is referred to merely to aid in describing it. The question, therefore, on which the validity of the patent depends is whether the fabric is new, or has been previously, in whole or in part, anticipated. On this question it is brought into comparison with the prior British patent of James Booth in 1881. There are other references, but, without stopping to discuss them, the case seems to turn on this one. Unquestionably imitation Astrakhan existed before either of these inventors; but it was the woven, and not the knitted, article, which Bywater was the first to actually produce. As said by Judge Dallas in his first opinion: “Knitted Astrakhan was created by Bywater, and this he accomplished not by merely applying the skill of the knitter to effect a change in either
In this arraignment of the patent there are concessions, large enough, as it seems to me, to produce a very different result. The fact that there are distinctions between the work of Booth and that of Bywater, and that Bywater, by a wise choice of yarn and patient work in mechanical development, produced the fabric which he did, goes a long way to meet the charge of the want of invention which is made. What is there'’ that makes up the inventive faculty beyond this? The error into which I can but feel that the learned court fell consists in the assumption that Booth not only had it in mind to make, but actually produced, a fabric which resembled knitted Astrakhan, and that Bywater merely improved upon it. The difference between the work of the two inventors is of no such incidental character. It may be that by adaptive manipulation an Astrakhan effect can be worked out with the Booth loops, but, taking the patent as it reads, it is clear that it will not be produced naturally. The only provision for creating loops is by the felting of the back or body by
No doubt it is not every slight advance in the art, such as is constantly being made by mere mechanical skill and adaptation, that is to be considered as invention. The design of the patent laws, as it is said in Atlantic Works v. Brady, 107 U. S. 199, 2 Sup. Ct. 231, 27 L. Ed. 438, “is to reward those who make some substantial discovery or invention which adds to our knowledge, and makes a step in advance in the useful arts.” It is at the same time recognized that the impalpable something which is said to distinguish invention from simple mechanical skill is at times not easy to discriminate or to define (McClain v. Ortmayer, 141 U. S. 419-427, 12 Sup. Ct. 76, 35 L. Ed. 800); and in the attempt to judge of it after the long lapse of years we are likely to be misled by the increased knowledge intermediately attained. That is the danger here. No knitter had produced Astrakhan cloth before Bywater, and how, then, can it be affirmed that any skilled knitter could? He could if he had the inventive genius to conceive it as Bywater did, but he could not without it. One criterion of invention is that others have sought and failed, even when the process is so simple, when discovered, that many believe they could have produced it if required. Walk. Pat. § 26. And why may that not be applied here? If, as it is stated, a gold medal was awarded Bywater by the Crystal Palace Wool Exhibition in
With the question of infringement—to which, by the way, the evidence of the defendants is mainly directed—I have no serious difficulty. The structure of the fabrics manufactured by them is displayed in the exhibits which have been produced, where the stitching of each is given in exaggerated form. These have been of the greatest assistance to me in the disposition of this part of the case. But notwithstanding the opinion of the experts which accompanies them, I am convinced that the great majority of these fabrics, if not in fact all, fall within the terms of the patent, and offend against it. As already seen, the inventor specifies with regard to his fabric that the face yarn is to be “looped at regular intervals, and on alternate stitches of adjacent rows of the back yarn, and, being matted and curly, and having a smooth back,” has the appearance of looped or Astrakhan cloth as described. That the greater portion of the defendants’ goods in outward appearance infringe upon the patent can hardly be denied. Some one or two in which the face yarn is of different colored threads, by which the diagonal lines of the looping is brought out, may not seem so much to do so. But it is the structure, rather than the appearance, which determines the infringement; or, rather, the appearance and the structure combined, the latter being the controlling feature. Turning, then, to the patent again, and analyzing its terms, we find that the looping of the face yarn must be “at regular intervals, and on alternate stitches of adjacent rows of the back yarn.” Admittedly these terms are not technical, and are to be construed according to their ordinary meaning, in which the opinions of experts are of little aid. By “regular intervals” we are to understand intervals that conform to a prescribed rule. This does not apply to the loops, be it noted, but to the intervals between; and by no means does each interval have to be a single stitch. Hence the loops may be of any desired irregularity, and pass over any number of stitches. Neither do I see why a regularity of intervals is not preserved where one set of loops of a certain fashion follows on after another, even though the interval between two immediately successive loops may not be the same. The intervals are not required to be equal, but regular, and this is satisfied by any repeated group or pattern. It further appears as an essential that the looping of the face yarn shall occur “on alternate stitches of adjacent rows of the back yarn.” This does not mean “every other stitch of successive rows,” as the defendants contend ; but, looking to the process of knitting and the’ course of the
Let a decree be drawn upholding the validity of the patent, and referring the case to a master to take an account.
