Stimpson v. Woodman/Dissent Clifford

Mr. Justice CLIFFORD, dissenting.

Inventions secured by letters patent are property, and as such they are under the protection of the Constitution of the United States and the laws of Congress. When duly secured in that way the patentee acquires the exclusive right, if the invention is a machine, to make and use the same and to vend it to others to be used during the entire term for which it was granted, as provided by law. Vested with that exclusive right he may have an action on the case to recover damages against any person who infringes his exclusive right; and on the trial of the case, to the jury he may introduce his letters patent in evidence, and when so introduced the letters patent afford a prim a facie presumption that the patentee is the original and first inventor of what is therein described as his improvement; and the defendant, if he denies that proposition, takes the burden to establish the affirmative of the general issue or of the notices filed in that behalf.

Letters patent bearing date the twenty-ninth of March, 1864, were granted to the plaintiff for a new and useful improvement in boarding and pebbling leather, which, as described, consists in giving to the surface of the leather a checkered or pebbled appearance by subjecting the leather on the finished side to the pressure of a short, engraved revolving cylinder or roller, made of steel or other suitable metal, having the required design or figure engraved on the periphery of the device. My improvement, says the patentee, consists in combining with said roller a certain new and useful combination of mechanical devices for carrying my invention into practical operation, so as to accomplish the object desired with great rapidity and cheapness.

Nothing can be plainer than is the meaning of those two passages in the specification, the substance of which is here reproduced. In the first passage he describes the result or effect which his invention will produce, and in the second he gives a terse general description of the invention itself, alleging that it consists in combining with the roller a certain new and useful combination of devices to accomplish the work. Had the patentee stopped there the specification might perhaps have been regarded as wanting that full, clear and exact description of the invention which is required by the sixth section of the Patent Act.

But the patentee did not stop there, as fully appears by what immediately follows in the specification. On the contrary, he gives a minute description of the roller, and then proceeds to describe the several mechanical devices to be combined with the roller, and which, as he says, will answer every purpose to produce the required effect; and in conclusion he gives a minute description of every element composing the organized machine described in the patent as it was issued.

Exact description is also given of the several devices composing the apparatus for raising and lowering the table on which the leather is placed as it is subjected to the operation of the pebbling instrument. Such an apparatus is essential to the effective operation of the machine, as the table must be raised in order that the leather may be subjected to the pressure of the roller or pebbling instrument as it passes over the upper surface, and it must also be lowered in order that the arm to which the pebbling instrument is attached may pass back, and it is obvious that the contrivance is ingenious and useful.

What the patentee claims is as follows: First, boarding or pebbling skins or leather by means of a single short cylinder rolling over a table with the requisite pressure substantially as described. Striking out the words substantially as described, it might be contended that the claim is for the effect and not for for the means by which the effect is produced, but such a construction cannot be maintained for a moment, as it would be contrary to the settled rules of law everywhere applied in such cases.

Patents for inventions are not to be treated as mere monoplies, and therefore as odious in the law, but they are to receive a liberal construction, and under a fair application of the rule that they be construed ut res magis valeat quam pereat. Hence where the claim immediately follows the description, it may be construed, says Curtis, in connection with the explanations contained in the specification, and be enlarged or restricted accordingly.

Construed in view of that rule, it is clear to a demonstration that the first claim of the patent is for the means described in the specification for accomplishing the effect, which is the exact view taken of the claim by the presiding justice in the court below.

Strike out the second claim and it might be contended that the first claim covers the whole invention, including the apparatus for raising and lowering the table as well as the combination of devices for pebbling the leather, but the whole specification must be construed together, and when so construed it is clear that the claims were intended to be distinct, as the second claim not only specifies the 'raising and lowering of the table,' but it also includes by name every one of the described devices to perform that office.

Giving due weight to these considerations, it is as clear as anything can be that the first claim of the patent is a claim for a combination of the described mechanical devices, with the roller for carrying the invention into practical operation, and for accomplishing the described result by the described means, excluding the apparatus for raising and lowering the table, which is included in the second claim.

Influenced by these considerations I dissent from the opinion of the court, because it adopts an erroneous construction of the patent, and one utterly at variance with the whole tenor of the specification and the language of the claim.

Some attempt was made at the trial to show that the invention of the plaintiff was superseded by the machine of Garnar, or by that of Green, but the attempt was an utter failure, and the jury found the issue in favor of the plaintiff. Questions of fact are certainly for the jury, and it is too plain for argument that the finding of the jury cannot be revised here under a bill of exceptions. Suppose, however, it were otherwise, still it would be impossible to come to any other conclusion than that their finding is right.

Take the Garnar machine, which is the first in order as the evidence is exhibited in the bill of exception. Evidence was introduced by the plaintiff, showing not only that the machine differed from the machine of the plaintiff, but that it operated in a substantially different manner, and produced a substantially different effect upon the leather, which must be obvious, upon comparing the two machines, to every one having any acquaintance with the subject. Equally decisive evidence was also introduced by the plaintiff showing that the Green machine did not supersede his patent. Among other things the plaintiff proved that the figuring instrument described in that patent was not a revolving instrument, but an instrument for rubbing the leather, as appears by the model; that the adaptation of the pebbling roller to that machine, so that the same could be practically used therein, would require invention and was not within the common knowledge and skill of a mechanic, and that a figured, rotating cylinder, such as is described in the plaintiff's patent, had not in fact been introduced and operated in that machine prior to the plaintiff's invention.

Remark upon the question of infringement is not necessary, as that issue was found by the jury for the plaintiff, and there is no exception calling for any review of the instructions given by the court.

Suggestion is made in the opinion just read that perhaps the judgment might be reversed upon the ground that the invention was not patentable. Patented inventions which are not new and useful, or which did not require any invention as compared with what existed, and was in use before, may doubtless be held invalid on that account, but the question whether a particular invention is new and useful, or whether it did require any invention to produce it, as compared with what existed before, are everywhere admitted to be questions of fact for the jury, and certainly no such question is open here for the determination of this court under this bill of exceptions. Such a remark cannot have been well considered, as the authorities are all the other way; but if it were otherwise the bill of exceptions shows that the finding of the jury was right, as it appears that the pebble finish can be made cheaper and better by the plaintiff's machine than by any other machine or instrument known in the trade, which is a complete answer to both suggestions.

Valuable as the property of the plaintiff in this invention is, I cannot concur in the judgment which assigns it to an infringer. Most modern patents are for new combinations of old elements, just like the present one, but many of them are of great utility, and they are as much within the protection of the patent law as those of any other class. Such patents being for the combination only, no one can be held liable for infringing the invention unless it be shown that the infringer uses all of the elements which compose the combination, showing that the public have the most ample security that nothing will be protected by the patent except what was in fact invented by the patentee.

Where an invention is for distinct combinations which are separable, and where it embraces two distinct improvements, one having respect to the operative part of the machine and the other to the motive power, it is entirely competent for the commissioner to grant separate claims for the two combinations in the same patent, or he may, under existing laws, grant separate patents for each combination, if it is new and produces a new and useful result.

Two combinations are embraced in this patent: one consisting of a combination of certain described mechanical devices with the roller to do the work of pebbling the leather, the other consists of the described combination to raise and lower the table; and the one last named is admitted to be new and useful, and therefore valid, but the opinion of the court surrenders the first one to infringers, and of course the property of the inventor is rendered of no value.
