32 F. 89 | U.S. Cir. Ct. | 1887
This is a bill in eqtiity for an injunction and accounting by reason of the alleged infringement of a patent issued to the complainant on the twenty-third day of January, 1877, for an “improvement in sofa bedsteads.” The improvement covered by this patent has reference to that class of sofas or lounges which may he opened or extended
Infringement is only charged in this case as to the second claim of the patent, which is in-the following words:
“In combination with the sections, A and B, the folding rods, F, F, and head-boards, D and E, supporting the latter, when extended to sustain the bolster, substantially as set forth.”
The lounge or sofa, under this patent, is constructed in two sections, the fixed section resting upon legs, and a folding section hinged to it so as to turn over in such manner that the under-side of the folding section should rest upon the top of the fixed section; and the folding rods, F, as they are called, consisting of iron rods benhU-shaped, the lower ends of which are pjvoted to the sides of the frames of the respective sections, so that they can be folded down into the inside of the frames when the sections are closed together, for the purpose of forming a sofa or lounge, and folded outwardly when the lounge is to be used for a bed, so as to .form a rest for the bolster or pillows used with the bed; one of the utilities, if not the main one, of these folding bolster rests, being to extend somewhat the length of the bed beyond the length of the sofa, as those folding rods, F, extend beyond the head of the sofa or lounge.
The defenses set up are (1) non-infringement; (2) that the patent is void for want of novelty.
The proof shows a large number, comparatively speaking, of prior devices for folding sofa beds, in which folding head-boards or head-pieces are shown; so that it may be assumed, as one of the established facts in this case, that folding bolster-rests or pillow-rests, for this class of beds, ■were not new with this inventor. In connection with the adjustable head-piece of this lounge, the patentee uses what he calls the head-boards, D and E, which are boards fastened to the head end of the lounge, outside of and to the end-pieces of the frames of the respective sections; and in describing the use of the folding rods, F, F, he says they may be turned Up out of the recesses in the sections where they rest, when the sections are closed so as to rest on the head-boards, to sustain the bolster as shown in Fig. 1 of the drawings; and the illustration of this operation of these bolster-rests shows these folding rods resting upon the head-boards, D and E, extending beyond the head of the lounge, so that the bolster and pillows would be even with, if not beyond, the end-pieces of the lounge.
The defendant makes a lounge in which he uses folding-rods constructed and operating precisely like the folding-rods in the complainant’s patent, except that instead of resting upon the head-boards, as shown in the complainant’s patent, they rest upon the end-pieces of the lounge-frame; the only object of their resting upon the head-board or lounge frame being to hold these rods at the proper angle to sustain the
It is so well settled that it hardly requires authorities at this time that the omission of one ingredient of a combination covered by any claim of a patent averts any charge of infringement based on that claim. Walker, Pat. § 349.
It is true, as already stated, that the end-pieces of the defendant’s lounge perform the same office with reference to these folding-rods that is performed by the complainant’s head-board; but the complainant has seen fit to make these head-boards elements of his patent, lie has brought them into his combination as essential parts of it; and the defendant has merely left out these head-boards, and constructed his bed, by pivoting these folding-rods upon Ihe sides of the Iraníes of the sections, dropping them slightly lower down than the complainant’s construction shows, and resting them upon the end-pieces of his frame. In other words, he has wholly dispensed with the head-boards shown in. the complainant’s patent. He has not substituted what is an equivalent for the head-boards in the complainant’s combination, but lias dispensed wholly with the head-board, and has used ihe end-pieces, which are not only in the complainant’s lounge, but probably all other lounges, as the fulcrum on which his folding-rods rest; so that the defendant cannot be said, it seems to me, to use the combination covered by this second claim because lie does not use the head-boards, but accomplishes the same result without their use. He throws the head-boards of complainant’s patent away, and uses the portions of the structure which arc left, without substituting anything in the place of the head-board which he has rejected. As is said in Water-Meter Co. v. Deeper, 101 U. S. 385:
“It is a well-known doctrine of patent law that the claim of a combination is not infringed if any of the material parts of the combination are omitted. It is equally well known, if anyone of the parts is only formally omitted, and and is supplied by a mechanical equivalent performing the same office and producing the same result, the patent is infringed. ”
Here the defendant omits one of the elements of the complainant’s combination, and substitutes nothing lor it, only using what he found in the complainant’s lounge, and in other lounges with these head-boards left out. It seems to me, therefore, the end-pieces of these lounge-frames are not to be considered as the equivalent of the head-boards in this claim of complainant’s patent. Complainant saw fit to make
It is, perhaps, unfortunate for this patentee that he did not see that any rest which would hold the folding-rods at the proper angle was just as useful as the head-boards, and it would hardly seem possible that a mechanic looking at a drawing or model of his lounge could have escaped the observation that the folding-rods might rest just as well upon the end-pieces of the frames as upon the head-boards; and therefore he might, if he had seen fit to do so, have covered the idea of resting the' folding-rods upon either the head-boards or end-pieces of his frame. In other words, any rest which would hold the folding-rods at the required angle might have been properly considered as his invention, if he had claimed it; but complainant saw fit to take his patent, so far as this feature of his device is concerned, upon the head-boards as an essential element of his structure, and the court can only protect him in what he has so claimed.
I am therefore reluctantly impelled to the conclusion that this defendant does not use the complainant’s patent, so far as it is covered by the second claim. The bill is therefore dismissed for want of equity.
