60 F. 411 | 7th Cir. | 1894
(after stating the case). The utterances of the supreme court upon the question whether or not a mechanical process is patentable are not in clear harmony; Corning v. Burden, 15 How. 267; O’Reilly v. Morse, Id. 62; Tilghman v. Proctor, 102 U. S. 707; Lawther v. Hamilton, 124 U. S. 1, 8 Sup. Ct. 342; Cochrane v. Deener, 94 U. S. 788; Brown v. Piper, 91 U. S. 37. In Lawther v. Hamilton, the process was for extracting oil from oleaginous seeds, and was not entirely mechanical; but the improvement for which the patent there considered was granted consisted merely in the omission of a mechanical part of the process, namely, the grinding of the seeds under muller stones, and the patent was sustained, though not in the broad and general sense of the claim; the process being held to be “limited by the clear terms of the specification, at least so far as the crushing of the seed is concerned, to the use of the kind of instrumentality described.” In Cochrane v. Deener, the original process and the patented improvement which was in issue, comprising the use of an air blast, related to the manufacture of flour, and were entirely mechanical in character and operation.
“A process,” it was there said, “is a mode of treatment of certain materials to produce a given result. It is an act, or a series of acts, performed upon the subject-matter to be transformed and reduced to a different state or thing. If new and useful, it is just as patentable as is a piece of mach'nory. In the language of the patent law, it is an art. The machinery pointed out as suitable to perform the process may or may not be new or patentable; whilst the process itself may be altogether new, and produce an entirely new result. The process requires that certain things be done with certain substances, and in a certain order; but the tools to be used in doing this may be of secondary consequence.”
But in Corning v. Burden, quoted with approval in Tilghman v. Proctor, it is said:
*414 “A process eo nomine is not made the subject of a patent in our act of congress. It is included under the general term ‘useful art.’ An art may require one or more processes in order to produce a certain result or manufacture. The term ‘machine’ includes every mechanical device or combination of mechanical powers and devices to perform some function or to pro1 duce a certain effect or result. But where the result or effect is produced by chemical action, by the operation or application of some element or power of nature or of some substance to another, such modes, methods, or operations are called processes. A new process is usually the result of discovery, a machine of invention. * * * It is when the term ‘process’ is used to represent the means or method of producing a result that it is patentable, and it will include all methods or means which are not effected by mechanism or mechanical combinations. But the term ‘process’ is often used in a more vague sense, in which it cannot be the subject of a patent. Thus we say that a board is undergoing the process of being planed, grain of being ground, iron of being hammered or rolled. Here the term is used subjectively or passively, as applied to the material operated upon, and not to the method or mode of producing that operation, which is by mechanical means, or the use of a machine, as distinguished from a process. In this use of the term it represents the function of a machine, or the effect produced by it on the material subjected to the action of the machine. But it is well settled that a man cannot have a patent for the function or abstract effect of a machine, but only for the machine which produces it.”
In general harmony with these propositions are the numerous cases of which, in Pennsylvania R. Co. v. Locomotive, etc., Truck Co., 110 U. S. 490, 4 Sup. Ct. 220, it is said:
“It is settled by many decisions of this court, which it is unnecessary to quote from or refer to in detail, that the application of an old process or machine to a similar or analogous subject, with no change in the manner of application, and no result substantially different in its nature, will not sustain a patent, even if the new form or result has not been before contemplated.”
In Brown v. Piper, 91 U. S. 37, a patent for a method of preserving fish in a closed chamber by means of a freezing mixture was held to have been anticipated by a like method practiced by undertakers for the preservation of dead bodies; and, to the proposition that the process had never before been applied to the preservation of fish and meats, the court said:
“The answer is that this is simply the application by the patentee of an old process to a new subject, without any exercise of the inventive faculty, and without the development of any idea which can be deemed new or original in the sense of the patent law. The thing was within the circle of what was well known before,, arid belonged to the public.”
And so, in Howe v. Abbott, 2 Story, 190, Fed. Cas. No. 6,766, a patent for the process of curling palm leaf for mattresses was held invalid in view of the fact that hair had been prepared by the same means for analogous uses. Justice Story said:
“It is precisely the same as if a coffee mill were now for the first time used to, grind corn. The application of an old process to manufacture an article to which it had never before been applied is not a patentable invention. There must be some new process or some new machinery used to produce the result. If the old spinning machines to spin flax were now first applied to spin cotton, no man could hold a new patent to spin cotton in all modes, although he had invented none.”
In Fuller v. Yentzer, 94 U. S. 288, where the claims, though in terms for the functioh' or result of the operation of the mechanism
“Patents for a machine will not he sustained if the claim is for a result, ⅛<⅞ established rule being that the invention, if any, within the meaning of the patent act, consists in the means or apparatus by which the result is obtained, and not merely in the mode of operation, independent of the mechanical devices employed; nor will a patent be held valid for a principle or for an idea, or any other mere abstraction. Burr v. Duryee, 1 Wall. 531.'’
And in Roberts v. Ryer, 91 U. S. 150, 157, is this expression:
“It is no new invention to use an old machine for a new purpose. The inventor of a machine is entitled to the benefit of all the uses to which it can be put, no matter whether he had conceived the idea of the use or not.”
To same effect, see Stow v. Chicago, 104 U. S. 550; Heald v. Rice, Id. 755; Stimpson v. Woodman, 10 Wall. 117; Tucker v. Spalding, 13 Wall. 453.
It being, as we suppose, well settled that a patent for a machine covers its use for all purposes, whether anticipated by the patentee or not, and that the functions or methods of operation of mechanical devices may not he patented, it would seem to follow that processes, which are to he effected wholly by mechanical means, in order to he patentable must be capable of being distinguished from the method of operation or mere function of the mechanism necessary for their accomplishment. Whether or not such processes are possible is a question primarily for inventors; the courts can decide only whether a particular process presented- for consideration is of that character. The processes now in question were designed for—
“Reducing and separating corn in the stalk at a single operation, so that the grains will be separated from the cob, and at the same time the stalk, husk, and cob are cut up or comminuted and [made] ready for use as stock food, — ensila ge. ”
The means specified for accomplishing these results are entirely mechanical, consisting of a combination of machines and devices long well known, and we find it impossible to see any distinction between the processes and the mere functions or mode of operation of the mechanism itself; and the same objection manifestly would apply if other devices were substituted for those described. But, if we waive the objection stated as one which under the decisions and dicta of the cases cited may or may not he tenable, and consider these processes in the light of the prior art in proof, we are constrained to find them devoid of patentable novelty. A completely analogous process is shown by the patent of Ford, Sullivan & Gregg, which is upon machinery designed for cutting, separating, and threshing wheat and other small grains. It is insisted, however, that cornstalks and ears in .the husk resemble trees more than wheat, oats, rye, or hai-ley, and that the process shown for the treatment of the latter afforded no suggestion for the treatment of the other by the same or a similar method; though it is admitted that if the cutting device of the Goddard patent were substituted for the cutting device of the 'Ford, Sullivan & Gregg machine, — a substitution which would not involve
The first two steps of the process covered by Goddard’s first claim are identical with the two steps which constitute the process of the second claim, and the fair presumption is that those two steps were first conceived or discovered, and that the third was devised later. The first inquiry in logical order, therefore, is whether or not in the two steps common to both claims there was a patentable discovery. The proof to the contrary is convincing. The only feature of novelty asserted is that Goddard was the first to conceive or discover that the shelling of corn, either wholly or in part, could be done by means of a feed cutter; and “this fact,” says the appellant’s expert, “lies at the bottom of his invention or process.” The same witness testified that “it has long been a practice among farmers to chop up ears of corn with an axe to fit it for feed for cattle;” that he did not know “that corn was ever- cut in the stalk, husk, or ear, with a feed cutter;” though he admitted that upon the cutters shown in the patents of Miller, Neff, Wentzel, and others, referred to in the prior art, without any change of parts or construction, the process of Goddard’s claim could be performed. Though not explicitly so stated, we think it inferable from this testimony that the practice of farmers was to chop up for feed the unhusked ears of corn, and it would seem entirely probable, because so manifestly practicable, if, indeed, the fact may not be affirmed upon common knowledge Within the cognizance of the. court, that the cutting was done upon the old-fashioned cutting boxes, as well as with axe or hatchet; and if com and husk and stalk together were. not cut in the same way, and especially by means of the improved and patented cutters -after they came into use, it was because an obvious and important utility for which the inventions were adapted was blindly overlooked or purposely rejected. On account of late planting, early frosts, and for other reasons, growing corn is often cut when the grain upon the ears is too immature to ripen after cutting into a merchantable article, and in that condition the farmer, already possessed of a cutter adapted for the purpose, needed no inventive suggestion to enable him to subject the stalk and ear together to the very process of which appellant would have a monopoly. It is hardly to be believed, in the absence of proof, that since the introduction of improved cutters, designed to reduce the entire product of the corn plant into a condition fit to be fed to cattle, they have not been used more or less to chop cornstalks and ears of com by a single operation, affording complete illustration of Goddard’s second process, both in respect to its operation and result. And this proposition does not rest on probability alone. The Harvey machine, patented iin 1867, which is in evidence, though called a straw cutter, was expressly designed “for cutting not only hay, straw, cornstalks, etc., but
