Majority — Black J.
delivered the opinion of the Court.
The question in this case is whether a State’s unfair competition law can, consistently with the federal patent laws, impose liability for or prohibit the copying of an article which is protected by neither a federal patent nor a copyright. The respondent, Stiffel Company, secured design and mechanical patents on a “pole lamp” — a ver
The District Court, after holding the patents invalid for want of invention, went on to find as a fact that Sears’ lamp was “a substantially exact copy” of Stiffel’s and that the two lamps were so much alike, both in appearance and in functional details, “that confusion between them is likely, and some confusion has already occurred.” On these findings the court held Sears guilty of unfair competition, enjoined Sears “from unfairly competing with [Stiffel] by selling or attempting to sell pole lamps identical to or confusingly similar to” Stiffel’s lamp, and ordered an accounting to fix profits and damages resulting from Sears’ “unfair competition.”
1 No review is sought here of the ruling affirming the District Court’s holding that the patent is invalid.
2 313 F. 2d, at 118 and nn. 6,7. At least one Illinois case has held in an exhaustive opinion that unfair competition under the law of Illinois is not proved unless the defendant is shown to have “palmed off” the article which he sells-as that of another seller; the court there said that “[t]he courts in this State do not treat the ‘palming off’ doctrine as merely the designation of a typical class of cases of unfair competition, but they announce it as the rule of law itself — the test by which it is determined whether a given state of facts constitutes unfair competition as a matter of law. . . . The ‘palming off’ rule is expressed in a positive, concrete form which will not admit of ‘broadening’ or ‘widening’ by any proper judicial process.” Stevens-Davis Co. v. Mather & Co., 230 Ill. App. 45 , 65-66 (1923). In spite of this the Court of Appeals in its opinions both in this case and in Day-Brite Lighting, Inc., v. Compco Corp., 311 F. 2d 26 , rev’d, post, p. 234, relied upon one of its previous decisions in a trade-name case, Independent Nail & Packing Co. v. Stronghold Screw Products, 205 F. 2d 921 (C. A. 7th Cir. 1953), which concluded that as to use *228 of trade names the Stevens-Davis rule had been overruled by two subsequent Illinois decisions. Those two cases, however, discussed only misleading,use of trade names, not copying of articles of trade. One prohibited the use of a name so similar to that of another seller as to deceive or -confuse customers, even though the defendant company did not sell the same products as the plaintiff and so in one sense could not be said to have palmed off its goods as those of a competitor, since the plaintiff was not a competitor. Lady Esther, Ltd., v. Lady Esther Corset Shoppe, Inc., 317 Ill. App. 451 , 46 N. E. 2d 165 (1943). The other Illinois case on which the Court of Appeals relied was a mandamus action which held that under an Illinois statute a corporation was properly denied registration in the State when its name was “deceptively similar” to that of a corporation already registered. Investors Syndicate of America, Inc., v. Hughes, 378 Ill. 413 , 38 N. E. 2d 754 (1941). The Court of Appeals, by holding that because Illinois forbids misleading use of trade names it also forbids as unfair competition the mere copying of an article of trade without any palming off, thus appears to have extended greatly the scope of the Illinois law of unfair competition beyond the limits indicated in the Illinois cases and beyond any previous decisions of the Seventh Circuit itself. Because of our disposition of these cases we need not decide whether it was correct in doing so.
Before the Constitution was adopted, some States had granted patents either by special act or by general statute,[3] but when the Constitution was adopted provision for a federal patent law was made one of the enumerated powers of Congress because, as Madison put it in The Federalist No. 43, the States “cannot separately make effectual provision” for either patents or copyrights.[4] That constitutional provision is Art. I, § 8, cl. .8, which empowers Congress “To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.” Pursuant to this constitu

The grant of a patent is the grant of a statutory monopoly;[5] indeed, the grant of patents in England was an explicit exception to the statute of James I prohibiting monopolies.[6] Patents are not given as favors, as was the case of monopolies given by the Tudor monarchs, see The Case of Monopolies (Darcy v. Allein), 11 Co. Rep. 84 b., 77 Eng. Rep. 1260 (K. B. 1602), but are meant to encourage invention by rewarding the inventor with the right, limited to a term of years fixed by the patent, to exclude others from the use of his invention. During that' period of time no one may make, use, or sell the patented
5 Patent rights exist only by virtue of statute. Wheaton v. Peters, 8 Pet. 591 , 658 (1834).
6 The Statute of Monopolies, 21 Jac. I, c. 3 (1623), declared all monopolies “contrary to the Laws of this Realm” and “utterly void and of none Effect.” Section VI, however, excepted patents of 14 years to “the true and first Inventor and Inventors” of “new Manufactures” so long as they were “not contrary to the Law, nor mischievous to the State, by raising Prices of Commodities at home, or Hurt of Trade, or generally inconvenient . . . .” Much American patent law derives from English patent law. See Pennock v. Dialogue, 2 Pet. 1 , 18 (1829).
Thus the patent system is one in which uniform federal standards are carefully used to promote invention
In the present case the “pole lamp” sold by Stiffel has been held not to be entitled to the protection of either a mechanical or a design patent. An unpatentable article, like an article on which the patent has expired, is in the public domain and may be made and sold by whoever chooses to do so. What Sears did was to copy Stiffens design and to sell lamps almost identical to those sold by Stiffel. This it had every right to do under the federal patent laws. That Stiffel originated the pole lamp and made it popular is immaterial. “Sharing in the goodwill of an article unprotected by patent or trade-mark is the exercise of a right possessed by all — and in the free exercise of which the consuming public is deeply interested.” Kellogg Co. v. National Biscuit Co., supra, 305 U. S., at 122 . To allow a State by use of its law of unfair competition to prevent the copying of an article which rep
7 The purpose of Congress to have national uniformity in patent and copyright laws can be inferred from such statutes as that which vests exclusive jurisdiction to hear patent and copyright cases in federal courts, 28 U. S. C. § 1338 (a), and that section of the Copyright Act which expressly saves state protection of unpublished writings but does not include published writings, 17 U. S. C. § 2 .
Sears has been held liable here for unfair competition because of a finding of likelihood of confusion based only on the fact .that Sears’ lamp was copied from Stiffel’s unpatented lamp and that consequently the two looked exactly alike. Of course there could be “confusion” as to who had manufactured these nearly identical articles. But mere inability of the public to tell two identical articles apart is not enough to support an injunction against copying or an award of damages for copying that which the federal patent laws permit to be copied. Doubtless a State may, in appropriate circumstances, require that goods, whether patented or unpatented, be labeled or that other precautionary steps be taken to prevent customers from being misled as to the source, just as it may protect businesses in the use of their trademarks, labels, or distinctive dress in the packaging of goods so as to prevent others, by imitating such markings, from misleading purchasers as to the source of the goods.[9] But because of the federal patent laws a State may not, when the article is unpatented and uncopyrighted, prohibit the
9 It seems apparent that Illinois has not seen fit to impose liability on sellers who do not label their goods. Neither the discussions in the opinions below nor the briefs before us cite any Illinois statute or decision requiring labeling.
