Chas. E. Mitchell and John P. Bartlett, for appellant.
Benj. Price and W. H. Thurston, for appellee.
Mr. Justice JACKSON delivered the opinion of the court. [150 U.S. 38, 39] The appellant brought this suit against the appellee for the infringement of two letters patent granted to Henry L. Spiegel for improvements in cabinet locks,-one being reissue letters patent No. 10,361, dated July 31, 1883, and the other No. 316,411, dated April 21, 1885,-both of which were assigned by Spiegel to Frank W. Mix. and by Mix to the appellant. They relate to what are known in the trade as 'machine' locks, so called from the fact that they are adapted for insertion in mortises cut entirely by machinery or routing tools, and thus distinguished from the 'old-style' lock previously used, which was adapted only for mortises cut or chiseled by hand. The locks covered by the patents are used chiefly on furniture.
It is alleged that the defendant's lock, which is substantially that covered by the Morris L. Orum patent of August i2, 1882, infringes the first claim of the reissue, and the three claims of the patent of 1885. The defenses set up as to the reissue are that the first claim thereof is for a different invention from that described in the original patent; that it is an expansion of the original claim, and is not infringed. As to the patent of 1885, the defenses interposed are that it is anticipated by other persons and patents, and want of patentability. The opinion of the court below, dismissing the bill, is reported in 37 Fed. Rep. 338. From that decree the present appeal is prosecuted.
The history of the art on this subject is so fully set forth in the opinion of Mr. Justice Brown in the case of Duer v. Lock Co., 149 U.S. 216 , 13 Sup. Ct. Rep. 850, (decided at the last term of this court,) that it need not be repeated here.
No special consideration was given by the court below to the first claim of the reissue patent, and, while it was not seriously insisted in oral argument before this court that there was error in the judgment of the court below on this branch of the case, counsel for appellant have nevertheless contended in their brief that the first claim of the reissue patent is valid, and was infringed. It becomes necessary, therefore, to examine the question raised on the reissue patent.
The original patent on which the reissue is founded was [150 U.S. 38, 40] No. 241,828, dated May 24, 1881. It appears from the file wrapper and contents that in his original application the patentee made three claims, the first being for 'cabinet lock having its rear plate projecting at each side of the lock-case, at G, G, substantially as and for the purpose specified;' the second was for a lock having such projecting rear plate, and having its front plate provided with a slit and strip; and the third claim was for a lock having such projecting rear plate, and having the upper part of such projection bent towards the front plate, as at G'. Each of these claims was rejected by the patent office,-the first and broader claim on reference to the Gory patent, No. 138,148, dated April 22, 1873, the second on reference to the Bishop patent, No. 201,219, dated March 12, 1878, and the third on the ground of no invention.
Having originally sought broader claims, which were rejected, and having acquiesced in such rejection, and having withdrawn such claims, and substituted therefor this narrower claim, describing a particular or specific lock, as such, neither the patentee nor his assignees can be allowed, under the authorities, to insist upon such construction of the allowed claim as would cover what had been previously rejected. Shepard v. Carrigan, 116 U.S. 593 , 6 Sup. Ct. Rep. 493; Roemer v. Peddie, 132 U.S. 313 , 10 Sup. Ct. Rep. 98; Royer v. Coupe, 146 U.S. 524 , 13 Sup. Ct. Rep. 166.
Aside from the operation of this estoppel, it is perfectly clear that the action of the patent office in rejecting the three original claims was correct, for the 'old-style' lock, which was in use long prior to the date of the Spiegel so-called invention, had a projecting front plate and a projecting rear plate, [150 U.S. 38, 41] which necessarily included a space between them. So, too, the lock of the Gory patent had a projecting rear plate, but lacked the bent-in feature and slitted front plate. But the Spiegel patent presented no patentable differences. The specification and claim of the original patent, as allowed, described and covered a lock, per se, of a special construction, and did not extend to or include anything in combination therewith.
'(1) A cabinet lock having its front plate and rear plate extending laterally beyond the body of the lock, in combination with the mortise, whose walls enter the space between the front and rear plate, whereby fastening screws are dispensed with, substantially as described.
'(2) A cabinet lock having its front plate and rear plate extending laterally beyond the body of the lock, and having also the edge, G', upon the rear plate bent toward the companion plate, substantially as described, and for the purpose specified.
Again, this first claim of the reissue clearly claim not warranted by anything appearing in the original specification. operates to broaden and expand the originaly operates to broaden and expand the original claim, in that it omits or contains no reference to any means whatever for holding the lock in place vertically, such as are described in the original claim. It drops out and eliminates elements shown in the original claim, such as the bent-in portion of the plate, and the slit, n, and strip, m, by means of which the necessity for fastening screws was to be dispensed with. This claim of the reissue was, for these reasons, clearly unwarranted. It does not appear that there was any accident, inadvertence, or mistake in the specification and claim of the original patent, or that it was void or inoperative for any reason such as would entitle the patentee to have a reissue thereof.
It is settled by the authorities that, to warrant new and broader claims in a reissue, such claims must not be merely suggested or indicated in the original specification, drawings, or models, but it must further appear from the original patent [150 U.S. 38, 43] that they constitute parts or portions of the invention, which were intended or sought to be covered or secured by such original patent. It is also settled by the authorities that in applications for reissue the patentee is not allowed to incorporate or secure claims covering or embracing what had been previously rejected upon his original application. Bantz v. Frantz, 105 U.S. 160 ; Heald v. Rice, 104 U.S. 737 ; Miller v. Brass Co., Id. 350; James v. Campbell, Id. 356; Topliff v. Topliff, 145 U.S. 156 , 12 Sup. Ct. Rep. 825. For these reasons, and other reasons which might be stated, we are clearly of opinion that the first claim of the reissue patent No. 10,361, dated July 31, 1883, is void, and that appellant was entitled to no relief in respect thereto, even if the original patent on which it was founded could be sustained as a valid patent.
In respect to the Spiegel patent of 1885 for improvements in cases for locks, we concur in the conclusion reached by the circuit court that it was invalid for want of patentable invention. We are further of opinion that in view of the state of the art, as shown by the 'old-style' lock, by the Gory patent of 1873, and by the Spiegel patent of 1881, the patent of 1885 was fully anticipated.
It was held by the commissioner of patents, under the interference already referred to, that this claim was lacking in patentability.
'(1) A lock case having a front plate formed with a rounded bottom; a cap plate forming, in connection with the front plate, intervening spaces or grooves on the opposite edges of the lock case; and a top plate extending over and beyond the cap plate; the projecting edges of the front plate being adapted to fit within a countersunk recess around the routed cavity within which the lock case is inserted,-substantially as set forth. [150 U.S. 38, 45] '(2) A lock case having a front plate formed with a rounded bottom; a cap plate secured to or connected with the front plate, and constructed to form therewith intervening spaces or grooves on opposite edges of the lock case; and a top plate extending over and deyond the cap plate, in combination with a support having a routed cavity provided with a countersunk recess adapted to receive the outer and projecting edges of the front plate,-substantially as set forth.
These claims were several times rejected by several different examiners and commissioners of the patent office, because they were lacking in patentable invention, and were anticipated by the prior state of the art and previous patents. How they came to be finally allowed and issued is wholly unexplained in the record.
The claim to invention in this patent of 1885 must rest upon differences which existed, if any, between the lock and the mortise therein described, and what was shown and disclosed in the prior state of the art, and in the Gory patent of 1873, and the Spiegel patent of 1881. In the lock of the patent of 1881, the front plate was straight at the bottom, instead of being rounded, as in the patent of 1885. This change involved nothing more than mechanical skill, so as to make the bottom of the front plate fit in the routed cavity, which was necessarily rounded. The further change described in the patent of 1885, of a countersunk recess to receive the projecting front plate of the lock, flush therewith, was not new, for such countersunk recess was frequently found in the old- style locks, when it was desired to make the front plate thereof flush, for the purpose of presenting a neat finish. This countersunk recess, used in connection with the old-style locks, was [150 U.S. 38, 46] made by hand chiseling, and was intended to present or produce a neat finish. The making of such countersunk recess for substantially the same purpose in the patent of 1885 by a routing tool, instead of by hand chiseling, did not rise to the dignity of an invention. The change involved nothing more than mechanical skill, which was produced by a change in the form of the routing machine.
Again, the Gory patent of 1873 shows a lock with a round bottom front plate, and it further shows that the front plate of that lock projects below the body of the lock, though it does not project at the sides, while the Sargent patent, No. 210,807, dated December 10, 1878, shows a lock having a round bottom front plate, which front plate projects below and at the sides of the body of the lock, as in the Spiegel lock, patented in 1885. The purpose of rounding the front plates at the bottom in both of the locks of the Gory and Sargent patents was to enable them to fit in a rounded or routed cavity. So the countersunk recess, made for the purpose of receiving the projecting front plate flush, was old, and called for no invention on the part of Spiegel. What Spiegel did in this respect was what had long before been done in the use of the old-style locks. The fact that he made his mortise, including the countersunk recess, with a routing tool, instead of by hand chiseling, certainly does not rise to the dignity of invention. In his arrangement of the lock and mortise, the lock is supported vertically by the selvage, and the sole object of letting the front plate in flush by means of the countersunk recess was to produce a neater finish and more attractive article than could be produced without such countersunk recess, or, as he expresses it in his specification, 'to conceal the cavity from view, and form a neat and finished appearance when in place.' All that Spiegel did was to make his mortise, including the countersunk recess, with a routing tool, so that it would be rounded at the bottom, and then make the front plate of his lock rounded to correspond with this rounded cavity, and fit in flush in the countersunk recess. This change exhibits no patentable subject of invention, over and above that which is disclosed in his prior patent of 1881, and shown [150 U.S. 38, 47] in the Gory and Sargent patents. These changes were simply obvious modifications of such prior patents, and cannot be sustained as a patentable invention.
We are of opinion, therefore, that there was no error in the decree below, and that the judgment should be affirmed.
Mr. Justice BROWN did not sit in this case, and took no part in its decision.
