Opinion of the Court
could not be faulted solely on the basis of its distribution. Id., at 442.
This analysis reflected patent law’s traditional staple article of commerce doctrine, now codified, that distribution of a component of a patented device will not violate the patent if it is suitable for use in other ways. 35 U.S.C. § 271(c); Aro Mfg. Co. v. Convertible Top Replacement Co., 377 U.S. 476, 485 (1964) (noting codification of cases); id., at 486, n. 6 (same). The doctrine was devised to identify instances in which it may be presumed from distribution of an article in commerce that the distributor intended the article to be used to infringe another’s patent, and so may justly be held liable for that infringement. “One who makes and sells articles which are only adapted to be used in a patented combination will be presumed to intend the natural consequences of his acts; he will be presumed to intend that they shall be used in the combination of the patent.” New York Scaffolding Co. v. Whitney, 224 F. 452, 459 (CA8 1915); see also James Heekin Co. v. Baker, 138 F. 63, 66 (CA8 1905); Canda v. Michigan Malleable Iron Co., 124 F. 486, 489 (CA6 1903); Thomson-Houston Electric Co. v. Ohio Brass Co., 80 F. 712, 720—721 (CA6 1897); Red Jacket Mfg. Co. v. Davis, 82 F. 432, 439 (CA7 1897); Holly v. Vergennes Machine Co., 4 F. 74, 82 (CC Vt. 1880); Renwick v. Pond, 20 F. Cas. 536, 541 (No. 11,702) (CC SDNY 1872).
In sum, where an article is “good for nothing else” but infringement, Canda v. Michigan Malleable Iron Co., supra, at 489, there is no legitimate public interest in its unlicensed availability, and there is no injustice in presuming or imputing an intent to infringe, see Henry v. A. B. Dick Co., 224 U.S. 1, 48 (1912), overruled on other grounds, Motion Picture Patents Co. v. Universal Film Mfg. Co., 243 U.S. 502 (1917). Conversely, the doctrine absolves the equivocal conduct of selling an item with substantial lawful as well as unlawful uses, and limits liability to instances of more acute
