 Opinion of the Court The rule on inducement of infringement as developed in the early cases is no different today. Evidence of “active steps … taken to encourage direct infringement,” Oak Industries, Inc. v. Zenith Electronics Corp., 697 F. Supp. 988, 992 (ND Ill. 1988), such as advertising an infringing use or instructing how to engage in an infringing use, show an affirmative intent that the product be used to infringe, and a showing that infringement was encouraged overcomes the law’s reluctance to find liability when a defendant merely sells a commercial product suitable for some lawful use, see, e.g., Water Technologies Corp. v. Calco, Ltd., 850 F.2d 660, 668 (CA Fed. 1988) (liability for inducement where one “actively and knowingly aid[s] and abet[s] another’s direct infringement” (emphasis omitted)); Fromberg, Inc. v.

Herman Miller Inc., 37 USPQ 2d 1080, 1090 (WD Mich. 1994) (evidence that defendant “demonstrate[d] and recommend[ed] infringing configurations” of its product could support inducement liability); Sims v. Mack Trucks, Inc., 459 F. Supp. 1198, 1215 (ED Pa. 1978) (finding inducement where the use “depicted by the defendant in its promotional film and brochures infringes the … patent”), overruled on other grounds, 608 F.2d 87 (CA3 1979). Cf. W. Keeton, D. Dobbs, R. Keeton, & D. Owen, Prosser and Keeton on Law of Torts 37 (5th ed. 1984) (“There is a definite tendency to impose greater responsibility upon a defendant whose conduct was intended to do harm, or was morally wrong”).

For the same reasons that Sony took the staple-article doctrine of patent law as a model for its copyright safe-harbor rule, the inducement rule, too, is a sensible one for copyright. We adopt it here, holding that one who distributes a device with the object of promoting its use to infringe copyright, as
