3 Wash. C. C. 443 | U.S. Circuit Court for the District of Pennsylvania | 1818
After an appearance of the defendant in error in the supreme court, and pleading, as it must be presumed he did, to entitle him to appear by counsel, and argue the cause, it is too late to take this objection. We must presume, that all formal objections, and particularly one to the want of the writ, were waived by consent of parties.
The jury being sworn, the competency of Philip Frederick, to give evidence for the defendant, was objected to by the plaintiff, on the ground that he uses a Stouffer hopper-boy; and that if the defendant should obtain a verdict, upon the ground of the use of the Stouffer hopperboy by others, prior to the plaintiff’s discovery, the court must declare the patent void; and thus incapacitate the plaintiff to recover against the witness.
BY THE COURT. This patent, according to the plaintiff’s claim, covers eleven distinct things; and may be perfectly good for a part, though not so as to this particular machine. If, therefore, the jury should find for the defendant, on the ground that the hopperboy
The deposition of Michael Former was offered, and objected to, for the reasons urged against it in the case of Evans v. Hettick [Case No. 4,562], The plaintiff’s counsel examined the clerk of the court, to prove what the practice had been; who states, that rules to take depositions generally, have frequently been entered in the office; and depositions of witnesses living within the state, and above one hundred miles from Philadelphia, have been taken; that it has been rare, for twenty years past, to take depositions under the act of congress [1 Stat. 88, § 30].
THE COURT rejected the evidence, for the reason assigned in Hettick’s Case.
The counsel for the plaintiff contended, that, under his patent, he was entitled to •claim, 1. The entire hopperboy, which is protected by the judgment of the supreme court in this very case (3 Wheat. [16 U. S.] 519); although it should appear that he was not the original inventor of it, which, however, they contended he was; and that the defendant’s -witnesses, who had testified as to the prior use of the Stouffer hopperboy, must be mistaken in their recollection of dates. 2. An improvement on a hopperboy. — That it is not necessary to the validity of such a patent, to describe in the specification, in what the improvement- consists, the 3d section of the law being, in this respect, merely directory to the secretary of state, authorizing him to refuse a patent, if such a specification be -not filed. But, however this may be in .common cases, they insisted, that the supreme court having decided that one of the plaintiff’s claims, under his patent, is to an improvement on the hopperboy (3 Wheat [16 U. S.] 517), the requisition (page 518) that he should show the extent of his improvement ■must necessarily mean, that he should show it by parol evidence; since tne chief justice having noticed, in the opinion, (page-515), that the specification does not. distinguish the improvement from the original machine, the .court would never have sent the cause to another trial, upon the plaintiff’s claim to an .improvement,, if the specification was deemed too defective to authorize his recovery.
(charging jury). This is an action for an infringement of the-plaintiff’s patent, which-the-plaintiff alleges to be, — 1. For the whole of the machine employed in the manufacture of flour, called the hopperboy. ,2. For an improvement on the hopperboy. The question is, is the plaintiff entitled to recover upon either of these claims? The question is stated thus singly, because the defendant admits, that he uses the very hopperboy for .which the patent is in part granted, and justifies himself by insisting, — 1. That the plaintiff was not the original inventor of the hopperboy, as patented, but that the same was in use prior to the plaintiff’s patent. 2. That his patent for an improvement is bad; because the nature and extent of the improvement are not stated in his specification; and if they had been, still the patent comprehends the whole machine, and is, therefore, too broad.
1. The first is a mixed question of fact and law. In order to enable you to decide the first, it will be well to attend to the description which the plaintiff has given of this machine, in his specification, of which a model is now before you. Its parts are — (1) An upright round shaft, to revolve on a pivot in the floor. (2) A leader or upper arm. (3) An arm set with small inclining boards, called flights and sweepers. (4) Cords from the leader to the arm, to turn it (5). A weight passing over a pulley, to keep the arm light on the.meal. (6) A cog at the top of the shaft to turn it, which is operated upon by the water power of the mill. The flights are so arranged, as to track, the one between the other, and to operate like ploughs; and at every revolution of the machine, to give the meal two turns towards the centre. The sweepers are to receive the meal from the elevator, and to trail it round the circle, for the flights to gather it to the centre, and also to sweep the meal into the bolt The use of this-machine is stated to be, to spread any granulated substance over a floor; — to stir and expose it-to the air, to dry and cool it and to gather it to the bolt
The next inquiry under this head is, when ■was this discovery made? Joseph Evans has sworn, that in 1783 the plaintiff informed him he was engaged in contriving an improvement in the manufactory of flour, and had completed it in his mind some time in July of that year. In 1784, he constructed a rough model of the'hopperboy; -but having no cords from the extremities Of the leader to those of the arm,- it was necessary, in making his experiments, to turn around the arm by hand. In 1785, he set up a hopperboy in his mill, resembling the model in court, and the machine described in his specification. The evidence of Mr. Anderson strongly supports this witness; and indeed, the discovery, as early as 1784, or 1785, is scarcely controverted by the defendant The defendant insists, that a hop-perboy, similar to the plaintiff’s, was discovered and in use many years anterior even to the year 17S3, and relies upon the testimony of the following witnesses: Daniel Stouffer, who deposes that he first saw the Stouffer hop-
' If these witnesses are believed by the Jury, they establish the fact asserted by the defendant, that the Stouffer hopperboy was in use. prior to the plaintiff’s discovery.
The next inquiry is into the parts, operation and use of the Stouffer hopperboy. — This consists of an upright square shaft, which passes lightly through a square mortise in an arm, underneath which are fixed slips of wood, called flights; and the arm is turned by a cog on the upper end of it, which is moved by the power which moves the mill. The arm, with the flights, operates as it turns upon the meal placed below it; and its use is, in a degree, to cool the meal, and to conduct it to the bolt It will now be proper to compare this machine with the plaintiff’s. They agree in the following particulars:— They each consist of a shaft a cog to turn it by the power of the mill, and an arm with flights on the under side of it They each operate on the meal, below the arm, to cool, dry, and conduct it to the bolt. In what do they differ? The plaintiff’s shaft is round, and consequently could not turn the arm, into which it is loosely inserted, if it were not for the cords, which connect the extremities of the arm to that of the leader. The shaft of the S hopperboy is square, and therefore turns the arm without the aid of a' leader or of cords. It has neither a weight nor pulley, nor are the flights arranged in the manner the plaintiff’s are; and consequently, it does not, in the opinion of most of the witnesses, cool, or prepare the flour for packing, as well as the plaintiff’s.
The question of law now arises, which is, —are the two machines, up to the point where the difference commences, the same in principle, so as to invalidate the plaintiff’s claim to the hopperboy, as the original inventor of it? We take the rule to be, and ■so it has been settled in this and in other courts, that, if the two machines be substantially the same, and operate in the same manner, to produce the same result — though they may differ in form, proportions, and utility, they are the same in principle; and the one last discovered, has no other merit, than that of being an improved imitation of the one before discovered, and in use, for which no valid patent can be granted to any one; because he cannot be considered as the original inventor of the machine. If the alleged inventor of a machine, which differs from another, previously patented, merely in form and proportions, but not in principle, is not entitled to a patent for an improvement; (which he cannot be, by the 2d section of the law;) he certain2y cannot, in a like case, claim a patent for the machine itself. The question for the jury, then, is, are the two hopperboys substantially the same in principle? — not, whether the plaintiff’s hopper-boy is preferable to the other? Because if that superiority amounts to an improvement, he is entitled to a patent only for an improvement, and not for the whole machine. In the latter case, the patent would be too broad; and therefore void, where the patent is single. If you are of opinion, that the plaintiff is not the original inventor of the hopperboy, he cannot obtain a verdict on that claim, unless his is an excepted case. The 1st, 3d and 6th sections of the general patent law [1 Stat. 318], conclusively support this opinion. But the judgment of the supreme court in this case (3 Wheat. [16 U. S.] 519) is relied upon by the plaintiff's counsel, to prove, that this is an excepted case; insomuch, that the plaintiff is entitled to a verdict, although you should be satisfied that he is not the original inventor of the hopperboy. That declares, “On consideration whereof, this court is of opinion, that there is error in the proceedings of the said circuit court, in this, that the said court rejected testimony which ought to have been admitted; and also in this, that in the charge delivered to the jury, the opinion is expressed, that the patent on which this suit is instituted, conveyed to Oliver Evans only an exclusive-right in his improvement in manufacturing flour and meal, produced by the general combination of all his machinery; and not to his improvement in the several machines applied to that purpose; and also, that the said Oliver Evans was not entitled to recover, if the hopperboy in his declaration mentioned, had been in use previous to his discovery.’’ But we are perfectly satisfied, that the interpretation put upon this clause, by the plaintiff’s counsel, is incorrect; and this for the following reasons: (1) The question of priority of invention, was not before the supreme court, and it is therefore incredible, that any opinion, much less a judgment,, would have been given upon that point. The error in the charge, which this part of the judgment was obviously intended to correct, is stated by the chief justice in the following words: — “This part of the charge seems to-be founded on the opinion that if the patent is to be considered as a grant of the exclusive use of distinct improvements, it is a grant of the hopperboy itself, and not for an-
Upon the whole, then, the court is of opinion, that Oliver Evans is not entitled to a verdict in his favour, as the inventor of the hop-perboy, if you should be of opinion, that another hopperboy, substantially the same as his in principle, as before explained, up to the point where any alteration or improvement exist in his hopperboy, was invented, and in use prior to the plaintiff’s invention and discovery, however they may differ in mere form, proportions, and utility.
2d. The plaintiff’s next claim is, to an improvement on a hopperboy; which claim, we were of opinion, in another case, has received the sanction of the supreme court. His counsel contend, that his improvement is —(1) On the original method of supplying the bolt by manual labour. (2) On his own hopperboy; — and (3) On some hopperboy invented by some other person. Let this position be analyzed: — (1) It is said to be an improvement on the original method by manual labour — But it is obvious, that if this be the invention, it is of an original machine; because, wherever the patent law speaks of an improvement, it is on some art, machine, o* manufacture, &c.; and not on manual la-bour, which was applied to the various arts, long before the invention of machinery to supply its place. (2) An improvement on his own discovery. But where is the evidence of such invention? It is true, that Joseph Evans has" stated, that the plaintiff constructed, in 1784, a rude model of a hopperboy; but it was no substitute for manual labour, because, without the cords or leading lines, the arm could not move; and it was, therefore, turned by hand. It was, in fact, in an incomplete state, — in progress to its completion, but not given out, or prepared to be given out, to the world, as a machine, before 1785, when the cords to turn the arm were added. (3) An improvement on a former machine. This is a fair subject for a patent; and the plaintiff has laid before you strong evidence, to prove that his hopperboy is a more useful machine than the one which is alleged to have been previously discovered and in use. If, then, you are satisfied of this fact, the point of law, which has been raised by the defendant’s counsel, remains to be considered; which is, that the plaintiff’s patent for an improvement is void, because the nature and extent of his improvement are not stated in his specification. The patent is for an improved hopperboy, as described in the specification which is referred to and made part of the patent. Now, does the specification express in what his improvement consists? It states all and each of the parts of the entire machine — its use, and mode of operating; and claims, as his invention, the machine, — the peculiar properties or principles of it, viz. the spreading, turning and gathering the meal; and the raising and lowering of its arm, by its motion, to accommodate itself to the meal under it. — But does this description designate the improvement, or in what it consists? where shall we find the original hopperboy described, either as to its construction, operation, or use; or by reference to any thing by which a knowledge of it may be obtained?— where are the improvements on such original stated? The undoubted truth is, that the specification communicates no information whatever, upon any of these points. This being so, the law, as to ordinary cases, is clear, that the plaintiff cannot recover for an improvement. The 1st section of the general patent law speaks of an- improvement as an invention; and directs the patent to issue for his said invention. The 3d section requires the applicant to swear, or affirm, that he believes himself to be the true inventor of the art, machine, or improvement, for which he asks a patent; and further that he shall deliver a written description of his invention, in such full, clear, and exact terms, that any person, acquainted with the art, may know how to construct and use the
If the general law upon this subject has been correctly stated, the next question is, is this an excepted case? It is contended by .the plaintiff to be so; 1st in virtue of the act for the relief of Oliver Evans; and, 2d, by the decision of the' supreme court (1) Under the private act; that, declares, that ■the patent is to be granted, in the manner and form prescribed by the general patent law. What constitutes the manner and form, in which a patent is granted by this law? .The obvious answer is, the petition, the .patent, with the signature of the president, and the-seal- of the United States affixed to .it — the oath,-or-affirmation — the specification, or description of the invention, as required by the 3d section — the drawings and model, if required. Will it be contended, that a patent would be granted in the manner and form prescribed by this law, if there were no description whatever of the invention? And if it would not, which is taken for granted, where is the difference between the total absence of a specification, and one which has no reference at .all to the invention for which the patent is granted? This Is not the case of an imperfect, or’ obscure description, but of one which relates exclusively to the whole machine; ■ whereas ,the invention, for which the patent is granted, is for an improvement only. (2) The opinion of the supreme court, which states, “that it will be .incumbent on the plaintiff, where .he claims for an improvement, to show the extent of this improvement” 3 Wheat. [16 U. S.] 518. But how is it to be shown? The .court has not pointed out the manner; and .we therefore think, the only fair implication is, that it must be shown as the statute of the United States, and the general principles of law require, — by. the patent and specification. If it may be shown by parol evidence to the jury, as the plaintiff’s counsel contend it may, then it may be fairly asked, cui bono? What sort of a showing would this be, so far as it could be productive of any useful purpose? As to this defendant, the evidence comes too late, to save him from the consequences of an error, however innocently committed. As to the public at large, with a view to caution during the continuance of the patent, and to information of the nature of the improvement, after its termination, the evidence..given in this cause, must be evanescent, and totally useless. • We feel perfectly convinced, that the meaning of the supreme court, as to this subject, is. again misunderstood by the plaintiff’s eojmsel; not only for the reasons above mentioned, but because the extent and construction of the plaintiff’s patent, and not the validity of it, in relation to any one of the machines, were the questions before that court; and none others, (in reference to. the charge,) were argued at the bar, or reasoned upon, by the chief justice, in delivering the opinion.
Upon the whole, we are of opinion, that the plaintiff is not entitled to a verdict, ■ for the alleged infringement of his patent, for an improvement on the hopperboy.
