11 F. Cas. 900 | U.S. Circuit Court for the District of Massachusetts | 1862
(charging the jury). This is a suit upon a patent which the defendants are alleged to have used, thereby violating the exclusive rights which the plaintiff claims.
A patent right, gentlemen, is a right given to a man by law where he has a" valid patent, and, as a legal right, is just as sacred as any right of property, and no more so; and questions respecting it are to be tried
There are three general-questions, gentlemen, that may arise. The first necessarily is whether this patent is valid. If it be, then the question arises, whether the defendants have infringed; and if so, the next question Is as to the amount of damages.
- • The first' and great question, which ■ has occupied the greatest part of the time, is of the validity of the patent. The plaintiff having obtained-a' patent from the government, it is incumbent on him, in the first instance, to produce the evidence of his having that grant to the exclusive privilege— to the invention; and when he produces that evidence he has performed that duty; he has laid before you his patent, and the presumption is that it is a valid one.
It makes a prima facie case for the plaintiff in the question of title; The defendant then undertakes to overthrow it by showing some reason why it ought not to have been ■granted-to him — why, therefore, it is not valid in- law.’ The reason assigned here, gentlemen, is that the plaintiff, Hayden, the patentee, was not the first inventor of the thing patented; and that is'the sole ground upon which it is contended that this patent is not legal and valid,.
To that, then, you 'will-direct'your inquiry 'in the first instance — was' Hayden the first ’inventor? Because If he was not, whether 'or-not he himself knew that it existed before, 'if in fact it was before known,'although he may have • been an inventor, an original inventor, yet, if' he wab not the first inventor, it would not give, him any exclusive privilege. The public had a right to it before hé invented it; he was not the first inventor, and the officers of the government had no authority, by law, to grant exclusive right to an individual of that to which the public had a previous right.
Was he then, gentlemen, the first inventor? The burden of proof to show that he was not, is upon the defendants, and they must maintain the allegation by a preponderance ■of the evidence to be .entitled to the verdict.
There are, then, two instruments; first, the machines used at Chicopee, and then those used by the Suffolk Company. With regard to the trunks used at Chicopee, .1 do not understand that it is contended by the counsel for the defendants that they were the same as the plaintiff’s; so as to invalidate the plaintiff’s patent; but they are relied upon 'as showing that certain steps were taken anterior to the plaintiff’s* patent, which diminish any merit or claim that he may have by virtue of his patent, by narrowing down the extent of his invention. The plaintiff’s invention is said to have been completed— and I believe there is no controversy upon that — in 1853. Those trunks, at Chicopee, were prior to that.
■ ' Now, gentlemen, it is necessary for you to determine, in the first place, what those trunks were, and for that purpose you should examine the evidence. There is controversy in the evidence as to what they were. It is-for you to determine whether they did contain the wire screen or not; and how far it was ■ similar to the wire screen which the-plaintiff sets forth in his patent; and which constitutes one of the material parts in his invention. And so far as you find that it was similar — that there was a wire screen ■in those trunks, and so far as you find that ■ they were substantially like the ■ plaintiff’s —so far as you find them alike, so far the invention had gone into usé; "the invention'of -the wire screen in trunks for cleaning cotton. 'But, as I observed before, it not being contended that they were so like the plaintiff’s as to invalidate the patent, I have no occasion to dwell' upon whether the' plaintiff’s •patent is invalidated or not.
v You come then, gentlemen, 'to the machine--from the Suffolk Company, about which" the great question has been raised in regard to priority. Now, then, you are to compare ‘two things; and the first step toward making a comparison is to ascertain what the two things are which you are to compare together. The thing secured by the plaintiff’s-patent is to be compared with' the trunk used by the Suffolk Company; there being no •controversy as to the dates here, as the trunk relied upon was used prior to the invention-in 1853. ' :
It is necessary, then, for you carefully to examine and see what the plaintiff’s patent is for, and what it secures to him.
This patent, gentlemen, is divided Into two-parts — the specification and the claim; the ■claim being the conclusion which has been referred to, and setting forth distinctly what it is he claims as his invention, and asks to-be secured to him by his patent. The specification, which precedes that, is referred to, read and examined, in connection with the claim, only to explain the claim and ascertain its true extent. We look at the claim in the first instance — which is .this; “Covering the partitions of an elongated trunk or box for cleaning cotton, or other fibrous substances, with a screen of woven wire, with the scores crossing the wire filled with metal or cement — the whole combined in the manner and for the purposes set forth in the specification.”
Now, gentlemen, you will analyze this and examine it; and see what are the essentials of the invention which is thus secured to him.
In the first place, there is an elongated box or trunk. In the next place, there are at the bottom of that, partitions. In the third place,' covering those partitions, is a screen of woven wire, and then a particular characteristic given to that description over and above the description, of its being one of woven wire, by saying: “Having its cross
As to the box, gentlemen, the only descrip.tion of the box given, is, that it is a trunk, an elongated trunk for the purpose of cleaning cotton or other fibrous substances. I • have not been requested to undertake to explain to you what an elongated trunk is.. I •have no occasion to go further than to leave it to your own judgment to determine what that description of a trunk is. - .
. I am not aware that there is any particular ■controversy or question about the partitions •underneath, nor any particular desire that ■the court should give you any explanation as ,to the meaning 'Of the patent in relation to those partitions. The screen, then, of woven • wire, is to cover this; and that screen must have its scores filled with metal or cement. And here, gentlemen, there is ■ a reference, .as there is throughout, to be had to the .specification that precedes, which specification undertakes to set forth what the inven•tion is, and to give instructions how to make ■an instrument — the improvement which the plaintiff says that he has made. 1 have not . examined the drawing, but you can do so if ■it throws any light upon the question. In that part of the specification which speaks of filling the scores, he says it may be done with metal, and then says by metal of a certain description, and he then says how it .may be applied — by dipping the wire in it. It says further, that shellac varnish may be •used — a varnish made of shellac and alcohol; therefore, gentlemen, as it is said expressly in the specification that varnish may be used for filling the scores, it makes the shellac ■varnish equivalent to the cement, as an equivalent mode of filling the scores; and not only expressly says that it may be used, but gives instructions as to the better mode of applying it, in order to fill the scores if that mode be adopted. It tells in what the shellac should be dissolved, and if only the upper side of the screen is to be covered by the varnish, in order to fill the scores, how .it should lie, horizontally, and the first coat should be put on by brushing across, and the next coat by brushing lengthwise, and directions to accomplish the end by filling -the scores if that material should be adopted by the constructor. And that is an essential part of this invention, so that if a person should use the elongated trunk, with its partitions covered by a screen of woven wire and combined in the manner set forth, and ■the scores of that screen were not filled with metal, cement, or what is equivalent to that as set forth in the patent for filling them— then it would be no violation of the plaintiff’s patent And so, if any other person has made such an instrument before it would not invalidate the plaintiff’s patent, This is not controverted, and I lay it down to you as the law applicable to the case.
Now, gentlemen, the plaintiff’s machine,-as described in his patent, is to govern you; any machines or models produced are only to illustrate what is in the patent; if they differ, the patent is to govern, for all that is secured or patented is that which is in his patent, and it secures all that is in his patent.
When you have satisfied yourselves, gentlemen, as far as is necessary, what the plaintiff’s invention, as secured by his patent is, you will then turn your attention to see what was the prior machine which is said to have existed, so as to invalidate his patent, for want of novelty — and that is, the Wright trunk.
Now, gentlemen, a difficulty presents itself in that investigation, and that is, you have not that trunk here — no patent for it Where a'question 'arises as to what a machine or structure was at a- former period, and especially which goes back for years— and, in this instance, I think about seventeen years — I think to about 1845; but whether old or recent, when you have to compare two things, one of them a structure or machine, it is a great satisfaction te have the structure or the machine before you, if it is a possible thing; or if it be of a size and character that it can not be brought into court, to have it now existing, so as to be open to examination, so that those persons who are interested in knowing what it is, having access to it, can make, by measurements or inspection, an exact model of what it is, and bring it into court, and show you what the thing is exactly. But, gentlemen, that trunk has passed away; it is not now, so far as the evidence goes, in existence, and that means, therefore, for ascertaining the character of it does not exist
The next means would be a model that had been made of a former machine, or structure, at the time it did exist Xou have no such model. Then a written description made at the time for the purpose of accurately delineating and setting forth what the machine or structure was; as in a patent or other description made for some important purpose— it is all very important if you can have -it The importance of it is in this, gentlemen, not only that it would contain a full, and it may be presumed an accurate description and delineation of the machine or structure; but that it was made at the time when it was certainly known what it was, and for the purpose of being a delineation, and has been subject to no change since; that is the importance of it, that when it is thus embodied in a model or in a written description or drawing, it remains unaffected by subsequent events. But in the want of such testimony, we must resort to the best that exists; and that is the memory of man.
! Now, gentlemen, it is for you to weigh- the ! evidence of every kind, and the evidence de
Now, the accuracy of knowledge at the time, as well as the ability of the man to testify the truth, depend very much upon the subject-matter. Some things that men have a full, clear, and perfect knowledge of at the time they transpire, may not be of that interesting character that they retain them in their memory. There are other things of which their knowledge at the time may not be perfect; and when you come to the question of machinery, a question of structure, the question whether the person had a full knowledge at the time may depend upon his habit of accurate observation, and his opportunity of observing the particular structure or machine, and his intelligence or understanding of it. For if he had not a clear idea at the time, of course he can not have immediately •afterward a very clear idea to communicate to others. You will consider, therefore, in : weighing the evidence as to what it is that the witnesses undertake to describe, how far you can rely upon their memory in undertaking now to say what that was; so that you can ascertain the instrument, the operations and effects, so as to compare that with the plaintiff’s machine.
Now, unfortunately, gentlemen, the witnesses differ in relation to this trunk at the Suffolk Mill. They differ, in the first place, as to the trunk itself. The whole structure | would present itself differently to the eye of him who went into the room and looked at it attentively, or only gave a passing glance at it
The witnesses for the defendant say that it was of the form of that which you have had, that it was in this room, building No. 3, connected with the opener; the opener facing to the westward, and the trunk extending at an angle from that toward the western wall, at the left, I think, some twenty-five feet, and then passing up in a curve through the ceiling into the room above, and then going horizontally eastward. That is the description of the external appearance of the trunk as given by the witnesses for the defendant.
The plaintiff’s witnesses say that the trunk there was different; that, in the first place, the opener did not face to the westward, but eastwardly, toward the partition; and that the opener was only a few feet, or not far from that partition; that then the trunk from that went eastwardly, toward the partition, a few feet, and then went up in a curve more or less regular, then straight, and then another curve, extending along under the ceiling of the same room, westwardly, and then went up in a curve to the room above, and then horizontal, eastwardly, to cross over. That, 1 believe, is substantially the testimony of the witnesses for the plaintiff.
Here you are met, gentlemen, with apparently a conflict of testimony, which, so far as you deem important, you will compare, examine, and weigh, and say which, on the whole, you think preponderates. Then when you go to the internal structure, what was inside of it, there was a conflict of testimony between the witnesses. The defendants say that there was a wire gauze screen. The plaintiff’s witnesses say that there was no wire screen there, or if any there, a very short distance from the opener toward the wall.
Now, gentlemen, that conflict of testimony you are to examine and consider, and say what is established — whether the inconsistencies in the recollection of the witnesses establish any thing; and if any thing, what? — er whether it leaves it in entire doubt; and if leaving it in entire doubt, then the party whose duty it is to prove it to you has not maintained the burden of proof.
Then there is another question that comes up. If that trunk had such a screen — had a screen of woven wire — were the scores filled with metal, or varnish, or cement, as required by the plaintiff's patent to make his instrument? And, gentlemen, instead of repeating the metal or cement, I shall hereafter speak only of the varnish, because that is the only thing that is in controversy, and the oniy thing that is alleged to be used, and therefore the metal need not be repeated.
Now, gentlemen, the plaintiff’s witnesses say that there was no screen there, or a very short one, and they do not speak particularly as to the varnish in the screen, because they did not see it. The defendants’ witnesses speak of the varnish, and it is for you to consider the force and effect of that testimony. What is proved? The proposition is that the scores were filled — that is the thing you are to inquire about, whether the scores of that screen were filled with shellac varnish. I say shellac varnish, because it is not contended that there was any other varnish used; and if there were, there is no proof of any other varnish used that answered the purpose.
Now you will observe in the claim, in the first place, it is said metal or cement; in the specification a certain thing is mentioned as equivalent to the metal, or what is set forth as equivalent — shellac varnish, or other kinds
You must look at the evidence, therefore, And satisfy yourselves. It is said by some •of the witnesses (I do not mean to detail the •evidence), whether more than one I do not recollect, because it is not my purpose to detail the evidence, that three coats were put •on. In what manner? Well, gentlemen, you will look at the evidence and see. In the first place, were there three coats, and in what manner were they put on?
Now, gentlemen, it may be material — you Are to determine how far it is material — to ■consider whether there is any evidence that the varnish was put on for the purpose of filling the scores, or for some other purpose.
If the varnish was put on for the purpose •of filling the scores; if that was the purpose and object in the mind of the party who directed it to be put on, there would naturally Arise a presumption that if the party was •competent for his work, that he accomplished the purpose for which he did it; but if. there was no such purpose, and that this was only an accidental result of putting it on for some other purpose, then you will judge whether there is any presumption that that was the accidental result, from the fact that it was put on. It may have been the result, although not intended, and that is for you to determine in considering the weight of evidence. If you take that into view you will see how far the presumption arises, and look at the purpose there was in putting on the varnish.
Now, gentlemen, you will consider whether it is proved to you that the scores were filled with varnish, and if proved to you that they were filled with varnish, is it proved to you that it was shellac varnish; and you will go back and see what the testimony is in that respect, and see whether there are witnesses that-spoke of it; what were their means of knowledge, at the time, of what kind thq varnish was; whether you can rely upon their memory, at this time, to tell you what the varnish was, so as to satisfy you that the scores were actually filled, and with shellac varnish.
That, gentlemen, I leave to you for your determination whether that has been established. If it is not by the preponderance of evidence, then that essential part of the plaintiff’s patent did not exist upon the Suffolk machine.
Gentlemen, I have thus far proceeded in calling your attention to matters to aid you in ascertaining what the structure was in the Suffolk Mills — in making a comparison, between the invention that is patented, and the machine that is said to have previously existed, in order to ascertain whether they were substantially the same. Other things may be taken into view beside the mechanical structure, the mode of operation and the effects produced.
And then, gentlemen,, you have to go back and ascertain the mode of operation, and the effects; particularly the mode of operation, if the structure differs.
Accordingly as the mechanical instrument is changed, its operation is changed, and the effects; and you must go back in order to make a comparison, and look at the evidence to see what were the effects of Mr. Hayden’s trunk. All the time I speak of Mr. Hayden’s trunk, I mean his trunk as set forth in the patent. You have the evidence of that, but I will say you must look at the evidence and see what were the effects of his patented machine; and then look at the Suffolk machine, and see what were the effects produced by that, and then, comparing the two, you will be aided in forming a judgment whether they were substantially the same, or not; and to what extent they were similar, and to what extent they differ. If the effect is the same, there-is no presumption that there is a difference in the structure. If the effects are different, it is a matter to be weighed by the jury how far is the difference between the causes, where they produce different effects. Although there has been, gentlemen, a great deal of evidence in that respect, as to the effects produced, I shall not go into the details of the evidence, for the remarks made as to the character and the weighing of evidence, apply to this as to all other parts of the case.
There is another thing to be taken into your consideration, gentlemen. Supposing that so
In determining the question, whether the mode of operation was the same, you will look not only at the evidence of the invention; you will look at the structure, the evidence of the structure; the evidence of the mode of operation; the evidence of the effect produced — that all goes to show whether it was an invention completed, perfected so as to be capable of practical use.
. There is another thing, gentlemen, which you are to take into view, and which may have a bearing upon this question of its being- a perfected machine, or noti-primarily, has a bearing upon the question of what the machine really was that was there; and whether it was a perfected invention — and that is, its abandonment. It is a matter for you to weigh. If there were experiments made, gentlemen, and they tend to a certain .point, and there is no certainty to what extent they went, then the subsequent conduct of the parties who madf* experiments, and were interested in it, may aid you in forming an opinion of what they accomplished. If they preserved it as a thing valuable, it has a weight in one direction as showing that they had accomplished something. If they did not preserve it but abandoned it— the evidence is to be weighed whether it was ■abandoned or not; whether a success had been obtained in any thing that was worthy of preservation, or could accomplish a practical and useful purpose; and the weight of this you will probably know is in proportion to the importance of the thing. There may be an invention, gentlemen, of so unimportant a character, that although it be really an invention, something of practical use, it may be in relation to a subject matter of so little importance, or of transient interest, that the occasion may pass by and it may be laid aside and never used afterward, 'because there is no occasion for it, as there are many patents for articles of dress of the day, which are patented for the day, while the fashion lasts, and pass away when the fashion passes away. On the other hand, if the invention be of something which can be of great practical .importance, an enduring importance, then you will consider how much stronger will be the incentive to success in perfecting that which would have been of importance; and the greater the importance of the invention, the less probable that if achieved it would have been laid.aside and not extended itself to others interested in its use.
Gentlemen, this is, as: I have already mentioned to you, a question of what existed some seventeen years ago. Now, T think it proper to say to you, that where an invention of any useful machine or structure, or improvement in any machine, is shown to have been made, and it is sought to be invalidated by an old machine made years ago, the jury should examine the testimony and the evidence with care and caution, so as- to be satisfled that that which is said to have existed, was actually and substantially the same.
The rule of law is a reasonable one; at all events it is a rule of law, that a party - who sets up such an old instrument that has passed away, has upon him the burden of satisfying the jury upon a preponderance of evidence that it is substantially the same as what has taken place, before they will set aside the patent. If they are so satisfied by the evidence, that it was substantially the same and known before, then it is their duty so to say when considering the patent
I come now, gentlemen, to another thing. If you are satisfled that the plaintiff was not the first inventor, then his patent is invalid, you have no occasion to go further, and must return a verdict for the defendants. If you are not satisfled, gentlemen, you come to another question: Whether the defendants have used the thing patented — whether they have infringed. And here the burden of proof is upon the plaintiff; because although the plaintiff’s patent creates a prima facie case for‘him, as to the validity of the patent, it creates no presumption that any person has infringed upon it And there is an admission, in this case, gentlemen, as to what the defendant uses, and has used, and did use, at the time before this-action was brought; and there is also testimony in the case, of the character of the trunk, particularly as to one of the trunks, by Mr. Grane, of Lowell. He testifies that he made a trunk, which was sold to the defendants, and that it was made exactly as Mr. Hayden’s trunk was; that it was sold to the defendants, and has been used by them since. You will, therefore, consider whether it is proved to you, whether the defendants have used the plaintiff’s invention, or not. If they have not. why then the verdict must, be for the defendants. If they
Now you have heard from the counsel various means for ascertaining it. You are to take the whole evidence, so far as it is applicable to that question, and inform your judgment from the whole. There is some evidence derived from General Oliver and Mr. Southworth, of the use, by the Atlantic Company, in Lawrence, and the company over which Mr. Southworth presides, in Lowell, of this machine of Mr. Hayden’s, by his consent, under particular circumstances, and its being subsequently referred to them, in connection with Mr. Thatcher, to determine what compensation should be paid. I understand, whether I am right or not, that that was in compensation for the use of it, as a license, during the existence of the patent, to use the thing; and they fixed upon a certain compensation which was named to you by General Oliver. That was not, as Mr. Southworth says, satisfactory to Mr. ■Hayden, and is not taken as any price that he fixed, or any agreement that that was a fair compensation to use his patent for the length of time, or a fair compensation for the circumstances under which he began to use it ■ But as that is evidence in the case,.yew will take it into view, and give it such weight as it deserves in estimating the damage tothe plaintiff. ■ Then you will look at the value-of' the thing used, to ascertain that value, by all the evidence that there is in the case-as to its character and performance and effects. Look at the value of that which the-defendants have used as belonging to the-plaintiff, and that may aid you in forming: a judgment of the actual damage the plaintiff has sustained. .
And here,.-gentlemen, I will remark, that you are to look :at this in ascertaining the-actual damage, -as you would in. any other case of property belonging to one man that has been used.by,another, to ascertain how much- of the rights of one man have been appropriated, temporarily, by another;' how much actual damage is. sustained by ..the-party whose right has. been infringed — to-look at it calmly and coolly, as you would in-relation to any- other.
And, incidentally, it has been mentioned in-the course of the examination with respect to the position of the plaintiff, and the capital of the defendants. The learned counsel have not presented you that as a ground for an increase or diminution of . damages; but as these -things have come out, I may suggest what your own good sense, no doubt, will suggest, that it is wholly immaterial what is-the .character or condition of the plaintiff or defendants. You do not know, gentlemen,because there is no evidence in the case, and the evidence could- not be brought .into the-case to show you, whether the plaintiff 1s a-poor man or a rich man. You do not know whether the defendants are poor or rich. It-is said that their capital is six hundred thousand dollars. Whether they have lost all that by unfortunate operations and are now worth nothing, or whether they have doubled-it, you do not know, gentlemen; and the reason you do not know is, that it is not a proper thing to be taken into account in the case.It is not evidence in the case as to the character or condition of the one party or the other. You are to give the same verdict against these defendants, whether it would ruin them, because they are not able to pay one hundred dollars, or five dollars, or whether they were worth a million; and you are to give Mr. Hayden the same amount in this case, whether he is worth nothing, or whether he is worth millions of dollars; equal justice, in both cases, covered by - the consideration of the actual damage sustained. You rest, gentlemen, upon your judgment, not on any matter of imagination or feeling; but in exercising your reasoning coolly, your sound judgment will, no doubt, arrive at a satisfactory conclusion, as in all other parts of the case.
I have been requested to say one thing which I believe, however, has been already involved in what I have said. If you come to the question of. damages, gentlemen, in considering
The jury returned a verdict for the plaintiff; damages, $1,744, equivalent to about $150 per annum for the use of each machine, or two and eight-tenths cents per spindle per annnm.
