The facts recapitulated in the statement just made are undisputed. Those which are seriously controverted, and upon which the legal issues depend are: First, were the sewing machines made by the Singer Company so, in whole or in part, protected by patents, as to cause the name 'Singer' to become, during the existence of the monopoly, the generic designation of such machines, as contradistinguished from a name indicati g exclusively the source or origin of their manufacture? Second. Irrespective of the question of patent, was the name 'Singer,' by the consent and acquiescence of Singer himself and that of the Singer Company, voluntarily used as a generic designation of the class and character of machines manufactured by I. M. Singer & Co. or the Singer Manufacturing Company, so that in consequence of this voluntary action the name became the generic designation of the machines, or was the name solely used by the company as a trade-name, a trade-mark, or one exclusively indicating machines made by I. M. Singer & Co. or the Singer Manufacturing Company?

We will consider these two controverted propositions of facts separately. Before doing so, we deem it well to say that on both these questions there are many conflicting and confusing statements in the record, adduced by both parties. Whatever may be their merit, they are not testimony in the proper sense of the word, being rather the expression of the opinion of the witnesses than substantive proof of existing facts. And the testimony of this character in favor of the respective parties, if allowed all possible weight, produces no affirmative result, since it is equally as strong by way of opinion on one side as it is upon the other. We shall therefore rest our conclusions on a consideration of the facts themselves, rather than upon the conflicting and irreconcilable opinions of witnesses.

1. It cannot be denied that the Singer machines were covered by patents, some of which were fundamental, some merely accessory. There can also be no doubt that the necessary result of the existence of these patents was to give to the Singer machines, as a whole, a distinctive character and form which caused them to be known as Singer machines, as deviating and separable from the form and character of machines made by other manufacturers. This conclusion is not shaken by the contention that, as many different machines were made by the Singer Manufacturing Company, therefore it was impossible for the name Singer to describe them, all, because the same designation could not possibly have indicated many different and distinct things. The fallacy in the argument lies in failing to distinguish between genus and species. To say that various types of sewing machines were made by the Singer Manufacturing Company in no way meets the view, borne out by the testimony, that all machines by them constructed were in some particular so made as to cause them all to be embraced under the generic head of 'Singer,' and to be protected in some respects by the patents held by the company. From this fact it resulted that during the life of the patents none of the machines as a whole were open to public competition. Persuasive support of this view is afforded by the fact that in many adjudicated cases, to which we shall have occasion hereafter to advert, where, since the expiration of the patents the right to the exclusive use of the name Singer has been asserted, it has, almost without exception, been found that Singer machines, as a whole, were a distinctive class, preserving a general uniformity of nature, however, varying may have been the types by which their structure was manifested.

It may be assumed that the proof establishes that for certain classes of the general type of Singer machines—that is, the species used only for particular and exceptional manufacturing purposes—an addition of some other word or description to the generic name Singer was necessary to completely convey a perfect indication of the machine referred to; that is, Singer 'carpet machine,' Singer 'leather machine,' etc. But this fact does not counterbalance the conclusive proof that, as a whole, the Singer machines represented a general class, and were known to the public under that comprehensive name, and no other. Indeed, any probative force which might result from the fact that, as to a particular class of Singer machines, some additional word may have been essentia to a perfect designation, bears no relation to the variety of the machine which the defendant is averred to have unlawfully imitated. That machine known as the 'New Family,' intended for general domestic purposes, constituted the larger part of the enormous output of the Singer Companies. It was of a uniform type, and had no other possible designation, in the mind of the general public, other than the word 'Singer.' The foregoing views find conclusive support from the unquestioned fact that upon the expiration of the patents held by the Singer Company the price of the machines made by that company fell enormously in amount. Thus, to adopt the theory advanced by the complainant, we should have to deny the inevitable law of cause and effect.

Abundant corroborative proof that the word 'Singer' became generically descriptive of the machines manufactured by the Singer Company is afforded by the conduct of that company. From the beginning every machine made by it had conspicuously marked on it the name of the manufacturer, 'I. M. Singer & Co.' or the 'Singer Mfg. Co.' Only occasionally was the word 'Singer' alone attached to any of the machines. This continued until the technical trade-mark came into play, which was about the time the patents expired. After this the trade-mark was affixed to the machines, and the name of the manufacturer, except as indicated by the trade-mark, disappeared, and was regularly supplanted by the word 'Singer' alone. The trade-mark then adopted could not have been essential to designate the source of manufacture, since from the inception the company had subserved that purpose by marking the name of the firm or corporation plainly upon the machines. The omission of the name, indicating the origin of manufacture, and the substitution of the word 'Singer,' just before the expiration of the patents, suggest a coincident relation of purpose which is not explained by any testimony in the record. This coincidence between the expiration of the patents and the appearance of the trade-mark on the machines and the use of the word 'Singer' alone tends to create a strong implication that the company, with the knowledge that the patents which covered their machines were about to expire, substituted the trade-mark for the plain designation of the source of manufacture theretofore continuously used, and added the word 'Singer,' which had become the designation by which the public knew the machine, as a distinctive and separate mark, in order thereby to retain in the possession of the company the real fruits of the monopoly when that monopoly had passed away.

2. Irrespective of the patents and the designative significance of the word 'Singer,' which arose during their life, the proof also clearly establishes that the word 'Singer' was adopted by I. M. Singer & Co., or the Singer Manufacturing Company, in their dealings with the general public, as designative of their distinctive style of machines rather than as solely indicating the origin of manufacture. This is demonstrated by the fact that at the inception of the manufacture of the machines the word 'Singer' alone was not used on them. The general method then adopted to indicate the source of the manufacture was to mark conspicuously on the machines the name of the firm or corporation. The name 'Singer' alone was used by the company on signs, on wagons, on advertisements, on bill heads, accompanied with the name of the firm or corporation. This could have had no other purpose than to denote to the public the corporation's understanding of the general name of the machines made by it. There is no proof that the name thus adopted by the corporation did not subserve this contemplated purpose of designating all the machines of whatever type, or that its inadequacy compelled the corporation to add to it, in particular cases, the word 'carpet' or 'leather' to describe machines intended for other than general domestic use. The conduct of the company in adopting the trade-mark and first affixi g the name at the time of the expiration of the patents, to which we have already adverted, is also of great significance in considering the question of the voluntary previous selection by the corporation of the word 'Singer' as a designation.

But the proof renders it unnecessary to base our conclusions upon the deductions to which we have just referred, since it contains affirmative testimony as to the purpose of I. M. Singer & Co., or the Singer Manufacturing Company, in their general use of the word 'Singer.'

William F. Proctor was sworn for the complainant, and his relations with the Singer Company are shown by the following excerpts from his testimony:

'Q. State in detail what connection you have had with the sewing machine business.

'A. I have been connected with the manufacture of sewing machines since 1853 up to the present time. I have been engaged in various capacities; first as a machinist with I. M. Singer & Co. I afterwards went to France for them for the sale of a patent, and established a manufactory of machines there. Since the Singer Manufacturing Company has become established, I have been a director since its origin, and an officer in various capacities, and am now its vice president.'

Continuing his examination in chief, the following questions were asked this witness:

'Q. 72. For what purpose and for what object was the name 'Singer' marked upon the machines of the complainant and its predecessors, and applied to them in advertising them?

'(Objected to by defendant's counsel as being merely accumulative and irrelevant to the issue.)

'A. To designate them, and after the formation of the company to gratify the desire of Mr. Singer to perpetuate his name associated with the machine.

'Q. 73. State what you mean by designating them.

'A. As a Singer machine.

'Q. 74. State whether the name was continued by the corporate successors of the firm for any otehr reason than to gratify the desire of Mr. Singer.

'(Objected to as suggesting the answer the witness is to make.)

'A. It was to continue the name.'

It is true that this conclusive statement, made by the vice president of the company, is followed in the continuation of his testimony by several leading questions, which could not have failed to suggest to him that it was desired that the statement thus made should be materially qualified. But the result of this effort to lead the witness rather strengthens than weakens the force of the testimony just quoted.

We conclude, then, upon the two pivotal and controverted questions of fact, which we proposed at the outset to consider——

First. That the Singer sewing machines were covered by patents which gave to the manufacturers a substantial monopoly; that in consequence of the enjoyment of this monopoly by the makers the name 'Singer' came to indicate, in its primary sense, to the public, the class and type of machines made by the Singer Company or corporations, and thus this name constituted their generic description; that also, as this name applied to and described machines made alone by the Singer firm or corporations, the use also came in a secondary sense to convey to the public mind the machines made by the firm or corporations.

Second. That the word 'Singer' was also voluntarily applied by the Singer firm or companies as a designation of the general type of machines made by them, with the intention that such machines should be accepted by the public under that name. Thus the course of the business and the purpose for which the name 'Singer' was used brought about results identical with those which sprang from the existence of the monopoly; hence that name became not only the description of the machines, but also, in a subordinate sense, the indication of the source of manufacture.

The case, as stated by the appellant in the pleadings and in the argument, fails to discriminate between distinct and different causes of action. The right to relief arising from the wrongful use by the defe dant of a specific trade-mark and from the illegal use of a trade-name, and also acts asserted to have been done by him which would justify the relief commonly accorded where unfair competition in business has been carried on, are commingled, and treated as one. Avoiding, for the sake of brevity, a statement of the elementary grounds upon which rest the law of specific trade-mark, of trade-name, or of unfair competition in business, and the distinction between them, it is sufficient to say that all the relief which complainant seeks is necessarily embraced in the following classification:

(1) Unfair competition in business, resulting from the form in which the defendant makes its machines, and also from the employment by it of the word 'Singer' in connection with the marks and devices on the machines, and the use of the same name in circulars and advertisements. (2) The alleged violation of the specific trade-mark of the complainant by the devices found on defendant's machines, and by the use of the word 'Singer.' We will examine these contentions. contentions.

First. Unfair competition in business, resulting from the form in which the defendant makes his machines, and also from the use made by him of the word 'Singer' in connection with the marks and devices on his machines, and the use of the same in circulars and advertisements.

This question subdivides itself into two inquires: Where the name of a patented machine, whether it be an arbitrary one or the surname of the inventor or manufacturer, has become, during the monopoly flowing from the patent, a generic description of such machine, and at the same time in a secondary and relative sense indicates to the public the source of manufacture, has the manufacturer, on the cessation of the monopoly, the right to prevent the making by another of a like machine in the form in which it was made during the life of the patents, and has he also a right to prevent another from calling such machines, by him made, by the generic name attributed to them during the monopoly, and from placing this name on them, and using it in advertisements, in circulars, and generally for such purposes as his interest may suggest? If no right exist in the original manufacturer to prevent another, under the foregoing circumstances, from making machines of like form and structure, and using the name, under the conditions stated, does the one who so makes and uses or sells them enjoy the liberty without any resulting duty whatever, or is it accompained with the obligation of so exercising the right as not to destroy the property of others, and also in such a manner as not to deceive the public?

It is self-evident that on the expiration of a patent the monopoly created by it ceases to exist, and the right to make the thing formerly covered by the patent becomes public property. It is upon this condition that the patent is granted. It follows, as a matter of course, that on the termination of the patent there passes to the public the right to make the machine in the form in which it was constructed during the patent. We may therefore dismiss without further comment the complaint as to the form in which the defendant made his machines. It equally follows from the cessation of the monopoly and the falling of the patented device into the domain of things public that along with the public ownership of the device there must also necessarily pass to the public the generic designation of the thing which has arisen during the monopoly in consequence of the designation having been acquiesced in by the owner, either tacitly, by accepting the benefits of the monopoly, or expressly by his having so connected the name with the machine as to lend countenance to the resulting dedication. To say otherwise would be to hold that, although the public had acquired the device covered by the patent, yet the owner of the patent or the manufacturer of the patented thing had retained the designated name which was essentially necessary to vest the public with the full enjoyment of that which had become theirs by the disappearance of the monopoly. In other words, that the patentee or manufacturer could take the benefit and advantage of the patent upon the condition that at its termination the monopoly should cease, and yet, when the end was reached, disregard the public dedication and practically perpetuate indefinitely an exclusive right.

The public having the right, on the expiration of the patent, to make the patented article, and to use its generic name, to restrict this use, either by preventing its being placed upon the articles when manufactured or by using it in advertisements or circulars, would be to admit the right, and at the same time destroy it. It follows, then, that the right to use the name in every form passes to the public with the dedication resulting from the expiration of the patent.

Nor is this right governed by different principles where the name which has become generic, instead of being an arbitrary one, is the surname of the patentee or original manufacturer. It is elementary that there is a right of property in a name which the courts will protect. But this right, like the right to an arbitrary mark or any other, may become public property by dedication or abandonment. The latter is defined by De Maragy, in his International Dictionary of Industrial Property, as follows:

'Abandonment in industrial property is an act by which the public domain originally enters or re-enters into the possession of the thing (commercial name, mark or sign) by the will of the legitimate owner. The essential condition to constitute abandonment is that the one having a right should consent to the dispossession. Outside of this there can be no dedication of the right, because there cannot be abandonment in the juridical sense of the word.'

But it does not follow, as a consequence of a dedication, that the general power vested in the public to make the machine and use the name imports that there is no duty imposed on the one using it, to adopt such precautions as will protect the property of others, and prevent injury to the public interest, if by doing so no substantial restriction is imposed on the right of freedom of use. This principle is elementary, and applies to every form of right, and is generally expressed by the aphorism, 'Sic utere tuo ut alienum non ledas.' This qualification results from the same principle upon which the dedication rests; that is, a regard for the interest of the public and the rights of individuals.

It is obvious that if the name dedicated to the public, either as a consequence of the monopoly or by the voluntary act of the party, has a two-fold significance, one generic and the other pointing to the origin of manufacture, and the name is availed of by another without clearly indicating that the machine upon which the name is marked is made by him, then the right to use the name because of its generic signification would imply a power to destroy any good will which belonged to the original maker. It would import not only this, but also the unrestrained right to deceive and defraud the public by so using the name as to delude them into believing that the machine made by one person was made by another.

To say that a person who has manufactured machines under a patented monopoly can acquire no good will by the excellence of his work, or the development of his business, during the patent, would be to seriously ignore rights of private property, and would be against public policy, since it would deprive the one enjoying the patent of all incentive to make a machine of a good quality, because at its termination all the reputation or good will resulting from meritorious work would be subject to appropriation by every one. On the other hand, to compel the one who uses the name after the expiration of the patent to indicate that the articles are made by himself in no way impairs the right of use, but simply regulates and prevents wrong to individuals and injury to the public.

This fact is ful y recognized by the well-settled doctrine which holds that, although 'every one has the absolute right to us his own name honestly in his own business, even though he may thereby incidentally interfere with and injure the business of another having the same name, in such case the inconvenience or loss to which those having a common right are subjected is damnum absque injuria. But although he may thus use his name he cannot resort to any artifice, or do any act calculated to mislead the public as to the identity of the busienss firm or establishment, or of the article produced by them, and thus produce injury to the other beyond that which results from the similarity of name.' Cement Co. v. Le Page, 147 Mass. 206, 208, 17 N. E. 304; Pillsbury v. Flour-Mills Co., 24 U. S. App. 395, 404, 12 C. C. A. 432, and 64 Fed. 841; Croft v. Day, 7 Beav. 84; Holloway v. Holloway, 13 Beav. 209; Wotherspoon v. Currie, L. R. 5 H. L. 408; Montgomery v. Thompson [1891] App. Cas. 217; Howard v. Henriques, 3 Sandf. 725; Meneely v. Meneely, 62 N. Y. 427; Lawrence Manuf'g Co. v. Tennessee Manuf'g Co., 138 U. S. 537, 11 Sup. Ct. 396; Chemical Co. v. Meyer, 139 U. S. 540, 11 Sup. Ct. 625; Coats v. Thread Co., 149 U. S. 562, 13 Sup. Ct. 966. Where the name is one which has previously thereto come to indicate the source of manufacture of particular devices, the use of such name by another, unaccompanied with any precaution or indication, in itself amounts to an artifice calculated to produce the deception alluded to in the foregoing adjudications.

Indeed, the enforcement of the right of the public to use a generic name, dedicated as the results of a monopoly, has always, where the facts of a monopoly, has always, where the necessary regulation to make it accord with the private property of others and the requirements of public policy. The courts have always, in every such case without exception, treated the one as the correlative or resultant of the other.

In Fairbanks v. Jacobus (1877) 14 Blatchf. 337, Fed. Cas. No. 4,608, it was sought to restrain the defendant from making or selling an imitation of Fairbanks' scales, and from casting the words 'Fairbanks Patent' upon scales so made in imitation of scales of the manufacture of the complainant. Johnson, J., held (page 339) that by reason of the expiration of the patents under which plaintiff manufactured his scales there was not, in the acts complained of, any invasion of the plaintiff's rights. The court said:

'Certainly, if the words 'Fairbanks Patent,' do not mean to assert the existence of a patent securing the scales, but only that they are made in conformity with, and embody the invention of, the expired Fairbanks patent, they are free to all the world. What is not free is to pretend that a scale is made by one person, which is, in fact, made by another.'

In Manufacturing Co. v. Larsen (1878) 8 Biss. 151, Fed. Cas. No. 12,902, it was sought to restrain the defendant from the use of the name 'Singer' in connection with machines manufactured or sold by him. Drummond, J., observed (page 152):

'On a machine called the 'Singer Sewing Machine' there were various patents. These patents have all expired, and nothing can, therefore, be claimed under them. Other persons cannot be prevented from manufacturing a machine like the Singer sewing machine, and which may be called, to distinguish it from other machines, 'Singer's Sewing Machine.' If a sewing machine has acquired a name which designates a mechanism or peculiar construction, parts of which are protected by patents, other persons, after the expiration of the patents, have the right to construct the machine, and call it by that name, because that only expresses the kind and quality of the machine.'

But in upholding the right a duty was also enjoined, the court adding:

'While I hold that the defendant is not prevented from constructing a 'Singer Sewing Machine,' still he cannot be permitted to do any act the necessary effect of which will be to intimate o to make any one believe that the machine which he constructs and sells is manufactured by the plaintiff. Neither has he the right to use any device which may be properly considered a trademark, so as to induce the public to believe that his machine has been manufactured by the plaintiff; and therefore I shall modify the injunction in this case by simply requiring the defendant to refrain from selling any Singer sewing machines manufactured by any person or company other than the plaintiff, without indicating in some distinct manner that the said machines were not manufactured by the Singer Manufacturing Company.'

In Manufacturing Co. v. Stanage (1881) 6 Fed. 279, Treat, district judge, said (page 280):

'The plaintiff and its predecessors had, in connection with others, through other patents, a monopoly as to certain sewing machines, known as the 'Singer Machines.' When these patents expired, every one had an equal right to make and vend such machines. If the patentees or their assignees could assert successfully an exclusive right to the name 'Singer' as a trade-mark, they would practically extend the patent indefinitely.'

The court entered into no discussion of the limitations resting on a party in the use of a name or designation dedicated to public use, because the facts rendered it unnecessary, the court saying (page 282):

'Sixth. The distinctive names and devices of the plaintiff corporation were not used by the defendant, and no one of ordinary intelligence could suppose that the 'Stewart' manufacture was the manufacture of the plaintiff. Each had its distinctive and detailed names and devices, so that there was no probability that the machine made by one would be mistaken for the manufacture of the other.'

In Manufacturing Co. v. Riley (1882) 11 Fed. 706, where a suit was brought to restrain the use of the word 'Singer' by the defendant in connection with sewing machines, the preliminary injunction was refused, following the decision in the Stanage Case. The court called attention to the fact that the word 'Singer' was not used on defendant's machines. It made no ruling as to the duty of the defendant to so use the name 'Singer' as not to deceive, because it found that the defendant's devices were not calculated to mislead.

In Brill v. Manufacturing Co. (1884) 41 Ohio St. 127, it was held (page 137 et seq.) that, as Singer machines had been protected by patents, and during the existence of such patents became known and identified in the trade by their shape, external appearance, or ornamentation, the patentee could not, after the expiration of the patent, prevent others from using the same modes of identification, in machines of the same kind, manufactured and sold by them. It was also held that the Singer machines had become known to the public by a distinctive name during the existence of the patent, and that any one at the expiration of the patent might make and vend such machines and use such name.

It would appear that the name 'Singer' had not been, directly or indirectly, marked upon the machines. It might also be inferred from the report of the case that the designation of defendant's machine was accompanied by a statement as to who was the manufacturer. At all events, the court did not discuss the obligation of the defendant to avoid misleading, since, under the facts, the question did not arise.

In Gally v. Manufacturing Co. (1887) 30 Fed. 122, it was held that the name 'Universal,' applied by a patentee to his patented printing press, upon the expiration of the patent could not be appropriated by the inventor as a trade-mark. Shipman, J., said (page 122):

'Any manufacturer who uses the name now does so to show that he manufactures the Gally press, which he may rightfully do, and does not represent to the public that it is getting any skill or excellence of workmanship which Gally possessed, and does not induce it to believe that the presses are manufactured by the plaintiff.'

The machines manufactured by the defendant, upon which was stamped the name 'Universal,' also bore the name of their maker.

Merriam v. Publishing Co. (1890) 43 Fed. 450, involved the right of the defendants to use the words 'Webster's Dictionary' in connection with a reprint of the 1847 edition of that work upon which the copyright had expired. Mr. Justice Miller, in the opinion delivered by him, said (page 451):

'I want to say, however, with reference to the main issue in the case, that it occurs to me that this proceeding is an attempt to establish the doctrine that a party who has had the copyright of a book until it has expired may continue that monopoly indefinitely, under the pretense that it is protected by a trade-mark or something of that sort. I do not believe in any such doctrine, nor do my associates. When a man takes out a copyright for any of his writings or works, he impliedly agrees that at the expiration of that copyright such writings or works shall go to the public, and become public property. I may be the first to announce that doctrine, but I announce it without any hesitation. If a man is entitled to an extension of his copyright, he may obtain it by the mode pointed out by law. The law provides a method of obtaining such extension. The copyright law gives an author or proprietor a monopoly of the sale of his writings for a definite period, but the grant of monopoly implies that, after the monopoly has expired, the public shall be entitled ever afterwards to the unrestricted use of the book.'

And the justice further observed (page 452):

'The contention that complainants have any special property in 'Webster's Dictionary' is all nonsense, since the copyright has expired. What do they mean by the expression 'their book,' when they speak of Webster's Dictionary? It may be their book if they have bought it, as a copy of Webster's Dictionary is my book if I have bought it. But in no other sense than that last indicated can the complainants say of Webster's Dictionary that it is their book.'

Although the right to use the words was thus adjudged, the duty not to deceive by the method of their employment was upheld and enforced, the court saying (page 451):

'Now, taking all these allegations together, there may be some evidence of a fraudulent intent on defendants' part to get the benefit of the reputation of the edition of Webster's Dictionary which the complainants are publishing, and it may possibly be that, in consequence of the facts averred, the public are deceived, and that the complainants are damaged to some extent. We think, therefore, that this in one of those cases where, as the facts are stated in the complaint, the interests of justice would be best subserved by requiring the defendants to answer, so that there may be a full and fair investigation of the law and facts upon a final hearing.'

In Merriam v. Shoe Co., 47 Fed. 411, a ruling similar to that announced by Mr. Justice Miller was made. But, although the right to use the words 'Webster's Dictionary' was sustained, the obligation to so use as not to mislead was again stated; Thayer, J., saying (page 414):

'It is unnecessary at this time to determine what form of relief should be administered if the allegations of the bill are proven on final hearing. It may be that some change in the form of defendants' circulars and advertisements will be all the relief that the circumstances of the case fairly warrant; or it may be that the proof will warrant an order that the defendants place a notice in their book that it is a reprint of the edition of 1847 of Webster's Dictionary, with such auditions as they may have made to it. This is a matter, however, to be considered on final hearing, when the exact nature of the injury and the causes that mislead the public are ascertained. It is sufficient to say at present that on the showing made the complainants are entitled to relief, and the demurrer to the bill is accordingly overruled.'

The principles thus maintained by the American cases are also supported by the English decisions.

In Manufacturing Co. v. Shakespear (1869) 39 Law J. Ch. 36, Vice Chancellor James refused to enjoin the use of the name of Wheeler & Wilson as a designation in advertisements of machines dealt in by the defendant. The advertisements of the defendant clearly indicated, however, that the machines in question were not manufactured by the plaintiffs. He said (page 40):

'I could not restrain the defendant from using the words 'Wheeler & Wilson' as descriptive of any sewing machine other than the sewing machine manufactured by the plaintiffs. It appeared to me that 'Wheeler & Wilson' was really not the name of the manufacturer or the name of the company, either abbreviated or otherwise, but the name of the thing in particular. As the plaintiffs' bill represents it, it is called 'The Wheeler & Wilson Sewing Machine,' and, there being no other designation for this particular machine, one can easily understand that that was the name of the patentee, or the person who at one time had the patent; for I take it that Wheeler & Wilson are not really the patentees' names, because the allegation in the bill is that they became entitled to the letters patent. It seems to me that the name 'Wheeler & Wilson' machine has come to signify the thing manufactured according to the principle of that patent. That being so, I cannot restrain anybody, after the expiration of the patent, from representing his article as being the article which was so patented. A man cannot prolong his monopoly by saying 'I have got a trade-mark in the name of a thing which was the subject of the patent,' and, therefore, to that extent I think the plaintiffs are not entitled to the relief they ask.' In Cheavin v. Walker (1877) 5 Ch. Div. 850, it was held that the trade-mark or label of the defendant, which fully stated that a filter to which it was attached, upon which the patent had expired, was made by him, did not infringe the trade-mark or label of the complainant, who had succeeded to the rights of the original patentee. In the court of appeals, James, L. J., said (page 863):

'It is clear that on the expiration of this patent is was open to all the world to manufacture the article which had been patented. That is the consideration which the inventor gives for the patent. The invention becomes then entirely publici juris. The plaintiff, and also the defendants, had a right to tell the world that they were making the article according to the expired patent, and both parties have done this. It is impossible to allow a man to prolong his monopoly by trying to turn a description of the article into a trade-mark. Whatever is mere descritpion is open to all the world. In the present case the plaintiff's label was nothing more than a description, and he cannot, therefore, have protection for it as a trade-mark.'

'The vice chancellor thought that the words 'Cheavin's Aptent' were calculated to deceive the public. But 'Cheavin's patent' is a correct description of the rinciple according to which the article was made, and there follows a distinct statement that it was manufactured by Walker, Brightman & Co. Therefore, on this ground also, the case made by the plaintiff's claim fails.'

In Manufacturing Co. v. Nairn (1878) 7 Ch. Div. 834, where the right to the exclusive use of the word 'Linoleum' was asserted, the substance to which the name was attached having been covered by patents which had expired, Fry, J., said (page 836):

'In the first place, the plaintiff have alleged, and Mr. Walton has sworn, that, having invented a new substance, namely, the solidified or oxidized oil, he gave to it the name of 'Linoleum,' and it does not appear that any other name has ever been given to this substance. It apppears that the defendants are now minded to make, as it is admitted they may make, that substance. I want to know what they are to call it. That is a question I have asked, but I have received no answer; and for this simpl reason that no answer could be given, except that they must invent a new name. I do not take that to be the law. I think that if 'Linoleum' means a substance which may be made by the defendants, the defendants may sell it by the name whcih that substance bears. * * *

'In my opinion, it would be extremely difficult for a person who has been by right of some monopoly the sole manufacturer of a new article, and has given a new name to the new article, meaning that new article, and nothing more, to claim that the name is to be attributed to his manufacture alone after his competitors are at liberty to make the same article.'

As the article manufactured by the defendant was clearly marked with the source of manufacture, the case was not one requiring the enforcement of the duty to designate the origin of the manufacture, but the court also said (page 837):

'If I found they were attempting to use name in connection with other parts of the trade-mark, so as to make it appear that the oxidized oil made by the defendants was made by the plaintiffs, of course the case would be entirely different. * * *

'It appears to me, therefore, that there has been neither infringement of any essential part of the plaintiffs' trade-mark nor any attempt on the part of the defendants to represent the goods which they intended to sell as goods made by the plaintiffs.' Page 838.

Nor is there anything in the Scotch case of Manufacturing Co. v. Kimball, 11 Ct. Sess. Cas. (3d Series) 267, or the English cases of Manufacturing Co. v. Wilson, 3 App. Cas. 376, 2 Ch. Div. 434, and Manufacturing Co. v. Loog, 8 App. Cas. 15, and 18 Ch. Div. 412, which in any way contravene the doctrines heretofore stated. In the Kimball Case, the fact that there had been no patents in England was expressly referred to, the court finding that for many years prior to 1870 machines like Singer machines had been manufactured under various names in England and Scotland by other parties than the Singer Company. It was upon these facts that the court based the right of the Singer Company to an exclusive trade-mark in the name. Indeed Lord Ardmillon (page 276) expressly declared that he regarded the facts above stated as distinguishing the case from the Shakespear Case, supra.

This distinction is also true of Manufacturing v. Wilson and Manufacturing Co. v. Loog. In neither was there a claim of a generic description as a consequence of a monopoly, and it becomes, therefore, needless to review these cases at length. It may, however, be said that both these cases recognize the right of a party in his advertising matter to state that his machines were constructed upon the Singer system or model.

The contention advanced by the complainant that his right to the exclusive use in the name 'Singer' after the expiration of the patents, although that name became the generic description of the machines during the monopoly, is in accord with the law of France, is without foundation. On the contrary, the French writers and courts recornize the doctrine to be substantially like that which is enforced in America and England. Braun, Marques de Fabrique, p. 232, § 68, says:

'The question is not whether an inventor can attribute to his patented invention a particular designation which remains the exclusive property of the patentee by the same title and for as long a time as the invention itself. This is evident, for without this right existing in the patentee his patent would be in certain respects illusory. But at the expiration of the patent, does the designation fall into the public domain with the patented invention? Does the patented thing lose the right to be solely individualized in favor of the inventor by the designation which up to that time has served as its mark. Three theories present themselves.'

After fully stating these three different points of view, the author adds:

'To resume, the three systems may be formulated as follows: (1) The designation of the thing patented becomes public property on the expiration of the patent. (2) The patentee retains in every case the sole use to the designation, after the expiration of his monopoly. If he had deposited the name [as a legal trade-mark] before the expiration of the patent. (3) The designation continues to belong to the patentee in every case but one, if the name given to the product has become the only and necessary designation of the patented article. We think there can be no hesitation in pronouncing in favor of the third proposition, except, however, that it requires to be completed by a second exception, which is that the name is also public property if in the interval which has elapsed between the expiration of the patent and the deposit of the trade-mark the inventor has allowed the designation to become public property.'

Pouillet, Brevets D'Invention, Nos. 327, 328, pp. 278, 279, reviews the opinions of the commentators and the decisions of the courts as follows:

'The expiration of a patent has for its natural effect to permit every one to make and sell the object patented; and it has also for effect to authorize every one to sell it by the designation given it by the inventor, but upon the condition in every case, not, in so doing, to carry on unfair competition in business [Concurrence D e Loyal] against him. Without this, say Pecard & Olin, the monopoly would be indefinitely prolonged, because in commerce one could not recognize the thing produced by the invention under any other designation than that given during the life of the patent. However, the question is not without difficulty, when the name of the inventor enters into the designation of the product. * * * In such case the courts should not allow third persons to employ the name of the inventor but with extreme caution, and by taking the most rigorous measures to prevent a confusion as to the origin of the product, which it would be very easy to abuse. It has been adjudged, conformably to these principles (Paris, 20th of January, 1844; Trib. comm.; Seine, 22d of December, 1853, Trib. comm.; Seine, 28th of July, 1853): (1) That the denomination under which a patented article is designated by the inventor falls into the public domain at the same time as the invention, at least when this denomination has been drawn from common language, and does not reproduce the name of the inventor himself; nevertheless the right to announce the product under the same denomination affixed to it by the inventor does not go to the extent of allowing its sale with the plates or stamps, or metallic paper, or tickets, or the manner of securing it, or the envelopes, or form or color analogous to that used in such a way as to cause appearances of deception. (Nancy, 7th of July, 1854, Verly, Sir., 1855, 2 vol. 581.) (2) That when an invention falls into the public domain, it enters with the name which the inventor has given it, and he cannot prevent a person from employing this designation. Thus, the inventor of the 'harmonium' was not allowed, after the expiration of his patent, to prevent others from making this instrument and selling it under the name which had been given to it. (Paris, 30th December, 1859, Pattaille, 1859, 414.) (3) That the patented invention falling into the public domain can be advertised and sold by the designation given to it by the inventor, even when the name of this last person figures therein. If by usuage and by the act of the inventor his name has become the necessary element to designate the product, it is essential, however, that the competitors of the inventor avoid all confusion which can induce the public into error as to the origin of the products.' (Cassation, 31st of January, 1860, Charpentier.)

'In principle, a surname is inalienable, and each one keeps the imprescriptible ownership in it. We know, however, that when the name of the inventor has become the designation of the thing patented, it belongs to every one at the expiration of the patent, to make use of this designation.' Pouillet, Brevets D'Invent on, p. 280, § 329.

The French decision mainly relied on by the plaintiff in error is that relating to the use of the surname 'Bully' in a toilet preparation known as the 'Vinegar of Bully,' but the facts upon which the case was decided are misapprehended. In that case the sole question was whether the surname 'Bully' had been either expressly or tacitly dedicated by him to the public by connecting it with his preparation. The court of cassation rested its decree upon the finding of fact by the court below, which was conclusive on it, that no such association of the name, by either the express or tacit consent of Bully, had ever taken place. We excerpt, briefly, the language of the court of cassation as reported in the Dictionary of De Marafy (volume 1, p. 11):

'Whereas, without doubt, the methods of manufacture of a patented product fall into the public domain after the expiration of the patent, but it is otherwise as to the name of the inventor, and that this rule suffers no exception, except in the case where, either by long usage or in consequence of a consent either expressly or tacitly given by the inventor, his surname having become the sole usual designation of his invention, it is employed to indicate the mode or the system of manufacture, and not the origin of the particular manufacture.

'Whereas, it is declared by the judgment appealed from, that Claude Bully has never manifested an intention to indissolubly bind up or unite his name for the benefit of his invention,' etc.

And the same distinction controlled the case of Howe, where the French courts enjoined the use of that name on a sewing machine. There the court, as a basis of its decree, used the following language: 'And whereas, they [Howe and his heirs] did not take patents in France for the invention and their improvements, which have therefore fallen into the public domain,' and have 'never, either expressly or tacitly, abandoned the right to affix his name [that of Howe] to the products of the invention.'

The result, then, of the American, the English, and the French doctrine universally upheld is this: That where, during the life of a monopoly created by a patent, a name, whether it be arbitrary or be that or the inventor, has become, by his consent, either express or tacit, the identifying and generic name of the thing patented, this name passes to the public with the cessation of the monopoly which the patent created. Where another avails himself of this public dedication to make the machine and use the generic designation, he can do so in all forms, with the fullest liberty, by affixing such name to the machines, by referring to it in advertisements, and by other means, subject, however, to the condition that the name must be so used as not to deprive others of their rights, or to deceive the public; and, therefore, that the name must be accompanied with such indications that the thing manufactured is the work of the one making it, as will unmistakably inform the public of that fact.

It remains only to apply these legal conclusions to the facts already recapitulated. Of course, from such application all claim of right, on the part of plaintiff in error, to prevent the use of the name 'Singer' is dispelled. This leaves only two questions: First, whether that name, as used in the circulars and advertisements of the defendant, is accompanied with such plain information as to the source of manufacture of the machines by them made as to make these circulars and advertisements lawful; and, second, whether this also is the case with the use of the word 'Singer' on the machines which the defendant makes and sells. As to the first of these inquires, the proof shows that the circulars were so drawn as to adequately indicate to any one in whose hands they may have come that the machines therein referred to were made by the June Manufacturing Company, and not by the Singer Company. We therefore dismiss the circulars from view. As to the advertisements, without going into etails, some of those offered in evidence were well calculated to produce the impression on the public that the Singer machines referred to therein were for sale by the June Manufacturing Company, as the agent or representative of the Singer Company.

On the second question the proof also is clear that there was an entire failure on the part of the defendant to accompany the use of the word 'Singer,' on the machines made and sold by him, with sufficient notice of their source of manufacture, as to prevent them from being bought as machines made by the Singer Manufacturing Company, and thus operate an injury to private rights and a deceit upon the public. Indeed, not only the acts of omission in this regard, but the things actually done, give rise to the overwhelming implication that the failure to point to the origin of manufacture was intentional, and that the system of marking pursued by the defendant had the purpose of enabling the machines to be sold to the general public as machines made by the Singer Company.

The marks on the machines are found on the oval plate and on the device cast in the leg of the stand. On the first of these (the oval plate) the words 'Improved Singer' are found in prominent letters, unaccompanied by anything to indicate that the machines were manufactured by the June Company, except the words 'J. M. Co.' and the monogram 'J. Mfg. Co.' The shape of the plate, its material, the position in which it was placed upon the machines, its size, its color, the prominence given to the words 'Improved Singer,' all could have conveyed but one impression to one not entirely familiar with the exact details of the device upon the Singer Company's plates, and that is that the machine was one coming from the factory of the Singer Company. So, in the second (the device cast in the legs of the stand), the word 'Singer,' alone without any qualification, is there found in bold relief, and above this the word 'I. S.' and in small letters 'J. Mfg. Co.' The similarity between the letter J. and the letter S., the failure to state in full the name of the manufacturer, the general resemblance to the device of the Singer Company, the place where it was put, which had no necessary connection with the structure or working capacity of the machines, and the prominence of the casting of the word 'Singer' in comparison with the other mark, brings out in the plainest way the purpose of suppressing knowledge of the actual manufacturer, and suggesting that it was made by the Singer Company. It is significant of the fraudulent purpose of the defendant that the device which the Singer Company cast in the legs of its machines was only by them adopted after the expiration of the patents and the resulting cessation of the monopoly, and for the avowed purpose of distinguishing their machines from others which had come upon the market; and therefore the colorable imitation which the defendant immediately proceeded to make had no necessary connection with the right to make machines according to the Singer system, and to call and sell them as Singer machines in consequence of their dedication to the public. But there are other circumstances in the record which throw light upon the facts which we have just stated, and lend to them an increased significance. On the plate of the Singer machines there was plainly marked a number, which the proof shows had run with relatively accurate consecutiveness from the beginning. These numbers, as a result of the vast development of the business of the Singer Company and the enormous number of New Family machines sold by them, ran into the millions. The defendant, who was in the commencement of his business, at once began also to number his machines in the millions, thereby conveying the obvious impression that they were the result of a manufacture long established, and as they were marked 'Singer' suggesting, by an irresistible implication, that they were machines made by the Singer Company. There is an attempt in the evidenc to explain this fact by the statement that it was the habit of sewing-machine makers to add three figures to the actual number of machines by them made, but the proof does not sustain the explanation, and if it did, it amounts to but the contention that the commission of a fraud should be condoned because others were guilty of similar attempts to deceive. There is another significant fact. On the machines made by the Singer Company there was a tension screw. This screw on the Singer machines served a useful mechanical purpose, and did not pass into the public domain with the expiration of the fundamental patents, because specially covered by a subsisting patent. The defendant, in making his machines, placed thereon a dummy screw, serving no mechanical purpose whatever, and which could have had no object but that of producing the impression that his machine was made by the Singer Company.

There remains only for examination the second proposition, that is:

2. The alleged violation of the specific trade-mark of the complainant by the device found on the defendant's machine and by the use of the word 'Singer.'

This question is necessarily involved in and determined by the foregoing considerations. There can be no doubt, if the right to use the word 'Singer' did not exist, that the plate and the device cast in the leg of the defendant's machine would be a plain infringement of the specific trade-mark of the Singer Company. There can also be no doubt that the marks used by the defendant would not constitute a specific infringement unless they contained the words 'Singer,' or a representation equivalent in the public mind to that word. It follows that the marks used by the defendant become only an infringement from the fact that each of them contained and embodied the word 'Singer.' But the word 'Singer,' as we have seen, had become public property, and the defendant had a right to use it. Clearly, as the word 'Singer' was dedicated to the public, it could not be taken by the Singer Company out of the public domain by the mere fact of using that name as one of the constituent elements of a trade-mark. In speaking of a mark containing composite words, some of which become dedicated to public use, others of which are not, Braun, in his Trait e des Marques de Fabrique, No. 135, pp. 354, 355, says: 'The surname, says a judgment of the court of Paris, is property in the most necessary and in the most imprescriptible sense. (Paris, 18th of November, 1875, Pattaille.) Does this mean that a mark composed of a name can never be lost? The courts, on the contrary, have decided that two elements which compose a name—that is, the surname of the individual or the firm upon the one side and its tracing or distinctive form' (in a trade-mark)—'are susceptible of falling into the public domain together or separately. In this last case the exclusive right to the trade-mark may survive the exclusive right to the name and vice versa. Thus one may keep the exclusive right to the use of the name, while the remainder of the mark will belong to every one.'

The right to use the word 'Singer,' which caused the imitative infringement in the device, being lawful, it is plain that the infringement only resulted from the failure to plainly state, along with the use of that word, the source of manufacture, and therefore this branch of the question is covered by the same legal principle by which we have determined the other.

It follows, therefore, that the judgment below, which recognized the right of the defendant to make or vend sewing machines in the form in which they were made by him—that is, like unto the machines made upon the principles of the Singer system with the use of the word 'Singer,' without a plain and unequivocal indication of the origin of manufacture, was erroneous.

Therefore the decree below must be reversed, and the cause be remanded, with directions to enter a decree in favor of complainant, with costs, perpetually enjoining the defendant, its agents, servants, and repres ntatives,—First, from using the word 'Singer,' or any equivalent thereto, in advertisements in relation to sewing machines, without clearly and unmistakably stating in all said advertisements that the machines are made by the defendant, as distinguished from the sewing machines made by the Singer Manufacturing Company; second, also perpetually enjoining the defendant from marking upon sewing machines or upon any plate or device connected therewith or attached thereto the word 'Singer,' or words or letters equivalent thereto, without clearly and unmistakably specifying in connection therewith that such machines are the product of the defendant or other manufacturer, and therefore not the product of the Singer Manufacturing Company. And the decree so to be entered must also contain a direction for an accounting by the defendant as to any profits which may have been realized by it because of the wrongful acts by it committed.

And it is so ordered.
