after stating the case, delivered the opinion of the court.

A. reversal of the decree in this case is asked on the grounds ■ that the words “ La Favorita,” as-used by the complainants;[*520] cannot be protected as a trade-mark; that there has been • no infringement; that the words had been used as a brand before ' being used by Holt & Co.; that the title of Holt & Co. was not superior to that of S. O. Ryder ; and that whatever rights complainants may once have had had been forfeited by laches.

The fact that Holt & Co. were not the actual manufacturers of the flour upon which they had for years placed the brand in question, does not deprive them of the right to be protected in the use of that brand as a trade-mark.

They used the words “La Favorita” to designate flour selected by them, in the exercise of their best judgment, as equal to a certain standard. The brand did not indicate by whom the flour was manufactured, but it did indicate the origin of its selection and classification. It was equivalent to the signature of Holt & Co. to a certificate that the flour was the genuine article which had been determined by them to possess a certain degree of excellence. It did not, of course, in itself, indicate quality, for it was merely a fancy name and in a foreign language, but it evidenced, that.the skill, knowledge and judgment of Holt & Co. had been exercised in ascertaining that the particular flour so marked was possessed of a merit rendered definite by their examination and of a uniformity rendered certain by their selection. The case clearly does not fall within the rule announced in Manufacturing Co. v. Trainer, 101 U. S. 51, 55, that “letters or figures which, by the custom of traders, or the declaration of the manufacturer of the goods to which they are attached, are only used to denote quality, are incapable of exclusive appropriation, but are open to use by any one, like the adjectives of the language;” or in Raggett v. Findlater, L. R. 17 Eq. 29, where an injunction to restrain the use upon a trade label of the term “nourishing stout” was refused on the obvious ground that “nourishing” was a mere English word denoting quality. And the fact that flour so marked acquired' an extensive sale, because the public had discovered that it might be relied on as of a uniformly meritorious quality, demonstrates that the brand deserves protection rather than[*521] that it should be debarred therefrom, on the ground, as argued, of being indicative of quality only. Burton v. Stratton, 12 Fed. Rep. 696; Godillot v. Harris, 81 N. Y. 263; Ransome v. Graham, 51 L. J. (N. S.) Ch. 897.

Holt & Co., then, having acquired the exclusive right to the words “ La Favorita,” as applied to this particular vendible commodity, it is no answer to their action to say that there was no invasion of that right because the name of S. O. Ryder accompanied the brand upon flour sold by appellants, instead of the name of Holt & Co. That is an aggravation and not a justification, for it is openly trading in the name of another upon the reputation acquired by the device of the true proprietor. Gillott v. Esterbrook, 47 Barb. 455; S. C. 48 N. Y. 374; Coats v. Holbrook, 2 Sandf. Ch. 586.

These views dispose of two of the defences specifically urged on behalf of appellants, and we do not regard that of prior public use, even if it could be properly considered under the pleadings, as entitled to any greater weight. Evidence was given to the effect that from 1857 to 1860 the words “La Favorita” were occasionally used in St. Louis by Sears & Co., then manufacturing in that city, as designating a particular flour, but the witnesses were not able to testify that any had been on sale there under that brand (unless it were that of Holt & Co.) for upwards of twenty years. The. use thus proven was so casual and such little importance apparently attached to it, that it is doubtful whether Sears & Co. could at any time have successfully claimed the words as a trade-mark, and at all events, such use was discontinued before Holt & Co. appropriated the words to identify their own flour, and there was no attempt to resume it.

It is argued, however, that the title of Holt & Co. to the. use of the mark was not superior to that of S. O. Ryder, because it is said that Ryder, upon leaving the firm, took with him his share of the good-will' of the business, and consequently of the trade-marks, and hence that the defendants .below rightfully sold flour under the brand “ La Favorita,” when selected by Ryder and so marked by him.

Good-will was defined by Lord Eldon, in Cruttwell v. Lye, [*522] 17 Ves. 335, 346, to be “nothing more than the probability that the old customers will resort to the old place; ” but Yice Chancellor Wood, in Churton v. Douglas, Johnson, V. C. 174, 188, says it would be taking too narrow a view of what is there laid down by Lord Eldon, to confine it to that, but that it must mean every positive advantage that has been acquired by the old firm in the progress of its business, whether connected with the premises in which the business was previously carried on, or with the name of the late firm, or with any other matter carrying with it the benefit of the business.

It may be that where a firm is dissolved and ceases to exist under the old name, each of the former partners would be' allowed to obtain “ his share ” in the good-will, so far as that might consist in the use of trade-marks, by continuing such use. in the absence of stipulation to the contrary; but when a partner retires from a firm, assenting to or acquiescing in the retention by the other partners of possession of the old place of business and the future conduct of the business by them under the old name, the good-will remains with the latter as of course.

Holt & Co. commenced business in 1845, and had had an uninterrupted existence under that name since 1855; the trade-mark in question was adopted by the senior member of the firm in 1861, and had been thereafter in continuous use; Ryder became a partner in 1861, and retired February 1,1869, when a circular was issued, in which he participated, announcing the dissolution by his, retirement,-the continuance of the business by the other partners under the same firm name, and the formation of another partnership by Ryder with one Rowland, • to transact the flour and ' commission business at' another place, under the name of Rowland & Ryder.

In addition to these facts it is established by the preponderance of evidence, that it was verbally agreed, at the time Ryder retired,, that he surrendered all interest in the brands belonging to Holt & Co. Ryder attempts to deny this, but his denial is so qualified as to’ render it unreliable as against the direct and positive character of, the evidence to ‘the con[*523] trary. Indeed, when asked why the brands were not made the subject of appraisement when he went out, as it was conceded all, the other property of the firm was, he says that it was because he “ gave up all right, title and interest to those valuable brands to Robert S. -Holt out of friendship, so there was no occasion for it.” In our judgment, Ryder’s claim to' any interest in the good-will of the business of Holt & Co., including the firm’s trade-marks, ended with his withdrawal from that firm,.

Counsel in conclusion earnestly contends that whatever rights appellees may have had were lost by laches; and the desire is intimated that we should reconsider McLean v. Flemming, 96 U. S. 245, so far as it was therein stated that even though a complainant were guilty of such delay in seeking relief upon infringement as to preclude him from obtaining an account of gains and profits, yet, if he were otherwise so. entitled, an injunction against future infringement might prop erly be awarded. We see no reason to modify this general proposition, and we do not find in the facts as disclosed by the record before us anything to justify us in treating this case as an exception.

The intentional use of another’s trade-mark is a fraud; and when the excuse is that the owner permitted such use, that excuse is disposed of by affirmative action to put a stop to it. Persistence then in the use is not innocent; and the wrong is a continuing one, demanding restraint by judicial interposition Avhen properly invoked. Mere delay or acquiescence- cannot defeat the remedy by injunction in support of the legal right, unless it has been continued so long and under such circumstances as to defeat the right itself. Hence, upon an application to stay waste, relief will not be refused on the ground that, as the defendant had been allowed to cut down half of the trees upon, the complainant’s land, he had acquired, by that negligence, the right to cut down the remainder, Attorney General v. Eastlake, 11 Hare, 205; nor will the issue of an injunction against the infringement of a trade-mark be denied on the ground that mere'procrastination in seeking redress for depredations had deprived the true proprietor of his legal right. Fullwood v.[*524] Fullwood, 9 Ch. D. 176. Acquiescence to avail must be such as to create .a new. right in the defendant. Rodgers v. Nowill, 3 De G., M. & G. 614. Where consent by the owner to the use of his trade-mark by another is to be inferred from his knowledge and silence merely, “ it lasts no longer than the silence from which it springs; it is, in reality, no more than a revocable- license.” Duer, J., Amoskeag Mfg. Co. v. Spear, 2 Sand-ford (N. Y.) 599; Julian v. Hoosier Drill Co., 78 Indiana, 408; Taylor v. Carpenter, 3 Story, 458 ; S. C. 2 Woodb. & Min. 1.

So far as the act complained of is completed, acquiescence may defeat the remedy on the principle applicable when action' is taken on the strength of encouragement to do it, but so far as- the act is in progress and lies in the future, the right to the intervention of equity is not generally lost by previous delay? in respect to which the elements of an estoppel could rarely arise. At the same time, as it is in the exercise of discretionary jurisdiction that the doctrine of reasonable diligence is applied, and those who seek equity must do it, a court might hesitate as to the measure of relief, where the use, by others, for a long period, under assumed permission of the owner, had largely enhanced the reputation of a particular brand.

But there is nothing here in the nature of an estoppel, nothing which renders it inequitable to arrest at this stage any further invasion of complainants’ rights. There is no pretence of abandonment. That would require proof of non-user by the owner or general surrender of the use to the public. The evidence is positive that Holt & Go. continuously used the trade-mark, always asserted their exclusive right- to it, and never admitted that of any other firm or person, and, in the instance of every party, including Ryder, Avho used this brand on flour flot of Holt & Co.’s selection, that use, when it came to their knowledge, was objected to by the latter, and personal notice given, while publication was also made in the newspapers, circulating Avhere the flour was usually marketed, containing a statement of Holt & Co.’s rights and warning against imitations. It is idle to talk of acquiescence in view of these facts. Delay in bringing suit there was, and such delay as to preclude recovery of damages for prior infringement, but there[*525] was neither conduct nor negligence which could be held to destroy the right to prevention of further injury.

The decree of the Circuit Court will, therefore, be

Affirmed.,
