delivered the opinion of the court.
This was a suit in equity brought September 24, 1912, in the United States District Court for the Western District of Kentucky, by the present petitioner, a Massachusetts corporation, against the respondent, a Kentucky corporation, together with certain individual, citizens of the latter State, to restrain infringement of trade-mark and unfair competition.
The District Court granted an injunction against the corporation defendant pursuant to the prayer of the bill. 206 Fed. Rep. 570. The Circuit Court of Appeals reversed the decree and remanded the cause with directions to dismiss the bill. 226 Fed. Rep. 545. An appeal was allowed by one of the judges of that court, and afterwards we allowed a writ of certiorari. Pursuant to a stipulation, the transcript of the record filed for the purposes of the-appeal was treated as a return to the writ. Under § 128, Judicial Code, as amended by Act of January 28, 1915, c. 22, § 2, 38 Stat. 803, the appeal must be dismissed, and the cause will be determined on the writ of certiorari.
*94 The essential facts are as follows: About the year 1877 Ellen M. Régis, a resident of Haverhill, Massachusetts, began to compound and distribute in a small way a prep-; a'ration for medicinal use in cases of dyspepsia' and some other ailments, to which she applied’ as a distinguishing . name the word “Rex” — derived from her surname. The word was put upon the boxes and packages in which the medicine was placed upon the market, after the usual maimer of a trade-mark. At first alone, and afterwards in. partnership with her son under the firm name of “E. M. Regis & Company,” she continued the business on a mod- ' est scale; in 1898 she recorded the word “Rex” as á trademark under the laws of Massachusetts (Acts 1895, p. 519, c. 462, § 1); in 1900 the firm procured its registration in the United States Patent Office under the Act of March 3, 1881, c. 138, 21 Stat. 502; in 1904 the Supreme Court of Massachusetts sustained their trade-mark right under the state law as against a concern that was selling medicinal preparations of the present petitioner under the designation of “Rexall remedies” (Regis v. Jaynes, 185 Massachusetts, 458); afterwards the firm established priority in the mark as against petitioner in a contested proceeding in the Patent Office; and subsequently, in the year 1911, petitioner purchased the business with the trade-mark right, and has carried it on in connection with its other business,’ which consists in the manufacture of medicinal preparations, and their, distribution and sale ■ through retail drug stores, known as “Rexall stores,” situate in the different States of the Union, four of them being in Louisville, Kentucky.
Meanwhile, about the year 1883, Theodore Rectanus, a druggist in Louisville, familiarly known as “Rex,” employed this word as a trade-mark for a medicinal prepara- . tion known as a “blood purifier.” He continued this use to a considerable extent in Louisville and vicinity, spending money in advertising and building up a trade, so that— *95 ( except for whatever effect might flow from Mrs', Regis.’ prior adoption of the word in Massachusetts, of which he was entirely ignorant — he was entitled to use the word as his trade-mark. In the year 1906 he sold his business, including the right to the use of the word, to respondent; and the use of the mark by him and afterwards by respondent was continuous from about the year 1883 .until the filing of the bill in the year 1912.
Petitioner’s first use of the word "Rex” in connection with the sale of drugs in Louisville or vicinity was in April, 1912; when two shipments of “Rex Dyspepsia Tablets,” aggregating 150 boxes and valued at $22.50, were sent to one of the “Rexall” stores in that city. Shortly after this the remedy was mentioned by name in local newspaper advertisements published by those stores. In' the previous September, petitioner shipped a trifling amount — five boxes — to a drug store in Franklin, Kentucky, approximately 120 miles distant from Louisville. There is nothing to. show that before this any customer in or near Kentucky had heard of the Regis remedy, with or without, the description “Rex,” or that this word ever possessed any meaning to the purchasing public in that State except as pointing to Rectanus and the Rectanus Company and their “blood purifier.” That it did and does convey the latter meaning in Louisville and vicinity is proved without dispute. Months before petitioner’s first shipment of its remedy to Kentucky, petitioner was distinctly notified (in June, 1911,) by one. of its Louisville distributors that respondent.'was. using the word “Rex” to designate its medicinal preparations, and that such use had been commenced by Mr. Rectanus as much as 16 or 17 years before that time.
There 'was nothing to sustain the allegation of .unfair competition, aside from the question of trade-mark infringement. As to this, both courts found, in substance, that the use of the same mark upon different but somewhat:
*96
related preparations was carried on by the parties and their respective predecessors contemporaneously, but in widely separated localities, during the period in question— between 25 and 30 years — in perfect good faith, neither side having- any knowledge or notice of what was being done by the other. The District Court held that because the adoption of the mark by Mrs. Regis antedated its adoption by Rectanus, petitioner’s right to the exclusive use of the .word in connection .with medicinal preparations intended for dyspepsia and kindred diseases of the stomach and digestive organs must be sustained, but without accounting for profits or assessment of damages for unfair trade; citing
McLean
v.
Fleming,
The entire argument for the petitioner is summed up in the contention that whenever the first user of a trade-mark ha^-been reasonably diligent in extending the *97 territory of his trade, and as a result of such extension has in good faith come into competition with a later user of the same mark who in equal good faith has extended his trade locally before invasion of Iris field by the first user, so that finally it comes to pass that the rival traders are offering competitive merchandise in á common market under the same trade-mark, the later user should be enjoined at the suit of the prior adopter, even though, the latter be the last to enter the competitive field and the former have already established a trade there. Its application to the case is based upon the hypothesis that the record shows that Mrs. Regis and her firm, during the entire period of limited and local trade in her medicine under the Rex mark, were making efforts to extend their trade so far as they were able to do with the means at their disposal. There is little in the record to support this hypothesis; but, waiving this, we will pass upon the principal contention.
The asserted doctrine is based upon the fundamental error of supposing that a trade-mark right is a right in gross or at large, like a statutory copyright or a patent for an invention, to either of which, in truth, it has little or no analogy.
Canal Co.
v.
Clark,
The owner of a trade-mark may not, like the proprietor
*98
of a patented invention, make a negative and merely prohibitive use of it as a monopoly. See
United States
v.
Bell Telephone Co.,
In truth, a trade-mark confers no monopoly whatever in a proper sense, but is merely a convenient means for facilitating the protection of one’s good-will in trade by placing a distinguishing mark or symbol — a commercial signature — upon the merchandise or the package in which it is. sold. •,
It results that the adoption of a trade-mark does not, at least-in the absence of some valid legislation enacted for the purpose, project the right of protection in advance of the extension of the trade, or operate as a claim of territorial rights over areas into which it thereafter may be deemed desirable to extend the trade. And the-expression, sometimes met with, that a trade-mark right is not limited in its enjoyment by territorial bounds, is true only in the sense that wherever the trade goes, attended by the use of the mark, the right of the trader to be protected against the sale by others of their wares in the place of his wares will be sustained.
Property in trade-marks and- the right to their exclusive use rest upon the laws of the several States, and depend upon them for security and protection; the power of Congress to legislate on the subject being only such as arises from the authority to regulate commerce with foreign nations, and among the several Státes and with the Indian tribes.
Trade-Mark Cases,
Conceding everything that is claimed in behalf, of the petitioner, the entire business conducted by Mrs. Regis and her firm prior to April, 1911, when petitioner acquired it, was confined to the New England States with inconsiderable sales in New York, New Jersey, Canada, and Nova Scotia. There was nothing in all of this to give her
*99
any rights in Kentucky, where the principles of the common law obtain.

Lathrop
v.
Commercial Bank,
8 Dana (Ky.), 114, 121;
Ray
v.
Sweeney,
It is not' contended, nor is there ground for the contention, that registration of the Regis trade-mark under either the Massachusetts statute or the act of Congress, or both, had the effect of enlarging the rights df Mrs. Regis or of petitioner beyond what they would be under common-law principles. Manifestly, the Massachusetts statute (Acts 1895, p. 519,' c. 462) could have no extraterritorial effect. And the Act of Congress of March 3, 1881, c. 138, 21 Stat. 502/ applied only to. commerce with foreign nations or the Indian tribes, with either of which this case has nothing to do. See
Ryder
v.
Holt,
Undoubtedly, the general rule is that, as between conflicting claimants to the right to use the .same' mark, priority of appropriation determines the question. See
Canal Co.
v.
Clark,
In several cases federal courts have held that a prior use of a trade-mark in a foreign country did not entitle its owner to claim exclusive trade-mark rights in the United States as against one who in good faith had adopted a like trade-mark here prior to the entry of the foreigner into this market. Richter v. Anchor Remedy Co., 52 Fed. *101 Rep. 455, 458; Richter v. Reynolds, 59 Fed. Rep. 577, 579; Walter Baker & Co. v. Delapenha, 160 Fed. Rep. 746, 748; Gorham Mfg. Co. v. Weintraub, 196. Fed. Rep. 957, 961.
The same point .was involved in
Hanover Milling Co.
v.
Metcalf,
In this case, as already remarked, there is no suggestion of a sinister purpose on the part of Rectanus or .the Rectanus Company; hence the passage quoted correctly defines the status of the parties prior to. the time where, they came into: competition in the Kentucky market. And it results, as a necessary inference from what we' have said, that petitioner, being the newcomer in that market," must enter' it -subject to whatever rights had previously been acquired there in good faith by the Rectanus Company and its predecessor. To hold otherwise — to require Rectanus to retire from the field upon the entry of Mrs. Regis’ successor — would be to establish the right of-the latter as a right in gross, and to extend it to territory wholly remote from the furthest‘reach of the trade to which it was annexed, with the effept not merely of depriving Rectanus of the benefit of the good-will resulting from his ^long-continued use of the mark in Louisville and vicinity, and his substantial expenditures in building up his trade, but of enabling petitioner to reap substantial benefit from the publicity that Rectanus. *102 has thus given to the mark in that locality, and of confusing if not misleading the public as to the origin of goods thereafter sold in Louisville under the Rex mark, for, in that market, until petitioner entered it, “Rex” meant the Rectanus product, not that of Regis.
■ In support of its contention petitioner cites the same cases that were relied upon by the District Court, namely,

Fleming,
