Reckendorfer v. Faber
Opinion of the Court
The bill of complaint herein charges the defendant with infringing three several patents—one issued March 30th, 1858, t.o Hymen L. Lipman, for a “combination of a lead pencil and eraser,” extended, on the 25th of March, 1872, for a further term of seven years from the 30th of March, 1S72, and assigned to the complainant; one granted to the complainant on the 4th of November, 1SG2, and reissued on the 1st of March, 1S70. for an “improvement in pencils;” and the third granted June 4th, 1872, to Teile Henry Muller, for an “improvement in lead pencils,” and assigned to the complainant. The answer denies that the respective patentees are the first inventors of the improvements claimed, denies that the defendant has infringed such patents, alleges that the patents are void on various grounds, but especially, by original and amended answer, avers prior invention, knowledge and use of the devices in question by various persons named, and that the invention had been in public use and on sale for more than two years prior to the respective applications for such patents.
The patent thirdly named in the bill of complaint does not appear in evidence, and was not the subject of examination or dis-
The patent to Lipman, in its specification, describes the invention thus: “I make a lead pencil in the usual manner, reserving about one-fourth of the length, in which I make a groove of suitable size, (A,) and insert in this groove a piece of prepared india rubber, (or other erasive substance,) secured to said pencil by being glued at one edge. The pencil is then finished in the usual manner, so that, on cutting one end thereof, you have the lead, (B,) and, on cutting the other end, you expose a small piece of india rubber, fC,) ready for use, and particularly valuable for removing or erasing lines, figures, &c., and not subject to be soiled or mislaid on the table or desk.” At the conclusion, the pat-entee states and claims: “1 do not claim the use of a lead pencil, with a piece of in-dia rubber or other erasing material attached at one end, for the purpose of erasing marks; but, what I do claim as my invention, and desire to secure by letters patent, is, the combination of the lead and india rubber, or other erasing substance, in the holder of a drawing pencil, the whole being constructed and arranged substantially in the manner and for the purpose set forth.”
The specification annexed to the reissued patent to Reekendorfer declares: “My invention is intended to provide a means whereby articles of a greater size or diameter than the lead may be securely held in the head of a pencil of otherwise ordinary or suitable construction, without making the body of the pencil cumbrous or inconvenient. To this end, my invention consists, first, of a pencil composed of a wooden sheath and lead core, having one end of the sheath enlarged and recessed, to constitute a receptacle for an eraser or other similar article, as hereinafter stated; second, of a pencil the wooden case of which gradually tapers from the enlarged and recessed head towards its opposite end, for the whole or a portion of the length, as hereinafter set forth. The receptacle for the eraser, or other article, is formed in the head, without too much weakening the wood, owing to the form of the sheath, while, for the same reason, the end of the pencil which contains the ordinary lead is not cumbrous, nor clumsy, but can be readily held between the fingers, just as an ordinary pencil is.” The further description shows that the groove in which the eraser is inserted is to be larger than the groove in which the lead is placed, as in the Lip-man pencil. Next:- “Pencils of equal size throughout have been heretofore made with a slip of rubber fitted in, in place of the lead, at one end, but such pencils have not become of any considerable practical importance. in consequence of the smallness of the rubber, and it has been held impracticable to make the rubber much larger, without too much weakening the wood, or making the entire pencil thick and awkward to han-die. By my invention, the size of the rubber may be so increased, while that of the lead remains the same, as to render it a very effective eraser, the size of the pencil head being such as to render it a convenient receptacle for a rubber of much more considerable size or diameter than the lead.” The claims are: “1. A pencil, composed of a wooden sheath and lead core, having one end of the sheath enlarged and recessed, to constitute a receptacle for an eraser, or other similar article, as shown and set forth. 2. A pencil, the wooden case of which gradually tapers from its enlarged and recessed head towards its opposite end, for the whole or a portion of its length, substantially as shown and described.”
Some observations, made in the progress of the argument, suggest the propriety of enquiring, and of stating what it is precisely, which these patentees profess, by their invention, to have improved. It was called, in the discussion, an “article of manufacture,” as distinguished from a machine having operation or action, and in which combined parts may operate reciprocally or conjointly, so as to produce results due to their concurring influence. Without conceding that the distinction stated can, in its application to the subject of these particular patents, have any influence on the enquiry, whether any patentable invention is disclosed by the patents, construed in view of the state of the art, and of prior knowledge and use, it is proper to say, that the subject of these patents, thougli not involving the complication of devices which entitle it to be dignified as a machine, is, nevertheless, a tool or implement, to be used or employed to produce useful results, as much so as a pen, a stamp for printing or embossing letters or figures, a hammer, or a file. All these are but instruments and mechanical agents, which are to be operated by the skill of the user, to effect a purpose. True, they are articles of manufacture, and put on sale. So is almost every description of tool, implement, and other mechanical device, which is of such general utility as to be the subject of general request in the market. If there was a general demand for a particular machine, of the most complicated combination of mechanical devices, it would be manufactured, and be found on sale, everywhere within the range of such general demand. To call the subject of these patents, articles of manufacture, in likeness to ready-made clothing, or, food, or medicine, would not truly represent their character or functions. It is a mechanical instrument, as much as a pen-knife, a corkscrew, a wrench, or a screw-driver; and the enquiry into its patentable character is — does it embody any new device, or combination of devices, producing a new result, or an old result in a different manner?
As a means of producing a mark, there is no pretence of its novelty. Pencils of the
I am constrained, by what I deem the preponderance of the evidence, to find, also, that, before either of the alleged inventions of the above named patentees, complete, practical, and useful pencils were made, and put into open, practical use for several years, for writing, drawing, and erasing, constructed by removing the lead from a portion of the groove in an ordinary lead pencil,, and substituting therefor, in such groove, india rubber, as an eraser. Thus, a form of combined pencil and eraser was produced, having one wooden sheath or holder, with lead as a marking material at one end, and an eraser of india lubber at the other, the marking material and the erasing material being each strengthened and protected, and in use, as they wore off, more and more exposed by cutting away the wood of the pencil constituting their sheath.
What then remained which could be the subject of a patent, there being no claim that the materials themselves, or the process of preparation, was, in any sense, new? This enquiry will be important to the question, how far the patents held by the complainant have any validity.
(1.) But, first, I prefer to enquire — what, in view of this state of the art, the patents, construed most favorably to the patentees, and assuming their validity, can be deemed to include; and, next, whether, when so construed, the defendant has infringed the patents. The language of the specifications aids in this enquiry, by recognizing, to some extent, the state of the ait above exhibited. Lipman declares that he makes a lead pencil in the usual manner. As a mere lead pencil, it has no novelty, and he claims nothing therefor. He inserts india rubber at one end, in which he makes a groove “of suitable size.” This is quite indefinite. A suitable size may be large or small. It will depend upon the use to which it is to be applied; but his drawing shows a groove larger than that of the lead. This groove is to be made in the wood of the pencil. In terms, he declares what, in view of what has already been suggested, he must have declared, that he does not claim “the use of a lead pencil with a piece of india rubber, or other erasing material, attached at one end, for the purpose of erasing marks.” He does claim “the combination of the lead and india rubber, or other erasing substance, in the holder of a drawing pencil, the whole being constructed and arranged substantially in the manner, and for the purpose, set forth.” He cannot claim, and does not claim, to have invented, broadly, an implement which is a combined pencil and eraser. Such implements were already in use. He cannot claim the mere combination of a lead pencil with an eraser, the lead and the erasing material having a common sheath. That was not new. For the same reason, he cannot claim such mere combination, when the sheath is of wood, susceptible of being cut away as the implement is worn by use; and, this, also, forbids his claiming, broadly, every snpposable mode of combining, within the holder of a drawing pencil, the material for erasing with the lead of the pencil. It follows, that, if the patent of Lipman be sustained, it must be limited to the construction which is exhibited in his specification, in those respects only in which it differs from those above described, that is to say, to the insertion, in the pencil holder, of an erasing substance, by means of a
It is argued, that, because this paper sheath can be cut away as the eraser is worn, it should be deemed an equivalent to the wood enclosing the eraser in the Lipman pencil. I am not willing to relax at all the just protection due to inventors against a merely evasive substitution of equivalents. But, it will be seen that the present patent, if valid, is not, broadly, for a combination of a lead, a holder, and an eraser; nor even for a lead and an eraser in the same sheath. It cannot be sustained, except for a special construction of the containing holder, and that is not adopted by the defendant. For the same reason, it is not material that, in one respect, the same result is produced, viz., that, in each, the sheath of the eraser can be cut away. If the construction is different, the mere producing of the same result does not make the defendant’s device an equivalent, where the special construction is the distinguishing and patented feature of the thing patented.
My conclusion is, therefore, that, if the Lipman patent can be sustained at all, its true construction is so limited by the state of the art and the disclaimer of the patentee, that the defendant’s pencil is no infringement.
The Reckendorfer patent is based upon that granted to Lipman, or rather it is applied to pencils constructed in like manner, so that, if the defendant does not infringe the one, he does not the other. It would be absurd to say, that making one end of a lead pencil larger than the other would be patentable. But, if it were patentable, the proofs show that pencils so made were not new, but were made, and in use, and on public sale, before the patent to Reckendorfer, and that such pencils were so made for the purpose of using the larger end to receive a cylindrical tube, as a penholder, while the other was left conveniently smaller, containing the pencil lead. Again, Lipman also made pencils with an enlarged end, to receive and hold the eraser. A pencil with a uniform taper, providing for an enlarged end, to become the recipient of some other device, was not new; and a pencil with an enlarged end, to receive and hold an eraser, was not new. There is little left, if anything, to be called invention, to be covered by Reckendorfer’s patent. But, give him the most favorable view of his device, and it superadds to Lipman’s devices the enlarged head and uniform taper of his pencil holder. In the very terms of his claim, it adopts the woodén sheath of Lip-man, recessed to constitute a receptacle for the eraser, and the wooden case gradually tapering from its recessed head towards its opposite end. The considerations which lead to the conclusion that the defendant does not infringe the Lipman patent, must, under the proofs above lastly referred to, result in holding that the defendant is not shown to infringe either patent.
(2.) The conclusion that the patents cannot, in view of the state of the art and of the disclaimer in the Lipman patent, be so construed as to charge the defendant as an infringer, renders it unnecessary to consider the case further. But I do not wish , to be regarded as affirming the validity of the patents relied upon by the complainant.
What did Lipman do or discover which can be called invention? Sticks grooved, and containing, in the groove, a marking substance — black lead and other materials— adapted to cutting away the wood as the marking substance was worn off, were common. Sticks containing an erasive material in a precisely like groove, and adapted to be cut away in like manner, were common, and the groove in these was of “suitable size”" to admit a useful eraser. Sticks are also-proved to have been in use and on sale, of precisely the same construction, having one
