Respondent the Massachusetts Institute of Technology is the assignee of U.S. Patent No. 6,108,703 ('703 patent), which
Petitioner Limelight Networks, Inc., also operates a CDN and carries out several of the steps claimed in the '703 patent. But instead of tagging those components of its customers' Web sites that it intends to store on its servers (a step included in the '703 patent ), Limelight requires its customers to do their own tagging.[1] Respondents claim that Limelight "provides instructions and offers technical assistance" to its customers regarding how to tag, 629 F.3d 1311 , 1321 (C.A.Fed.2010), but the record is undisputed that Limelight does not tag the components to be stored on its servers.

In 2006, respondents sued Limelight in the United States District Court for the
1 In its brief, Limelight disputes whether its customers actually "tag" within the meaning of the patent. Brief for Petitioner 7, n. 4. We assume arguendo that Limelight's customers do in fact "tag" within the patent's meaning.
Respondents' victory was short-lived, however. After the jury returned its verdict, the Federal Circuit decided Muniauction, Inc. v. Thomson Corp., 532 F.3d 1318 (2008). In that case the Court of Appeals rejected a claim that the defendant's method, involving bidding on financial instruments using a computer system, directly infringed the plaintiff's patent. The defendant performed some of the steps of the patented method, and its customers, to whom the defendant gave access to its system along with instructions on the use of the system, performed the remaining steps. The court started from "the proposition that direct infringement requires a single party to perform every step of a claimed method." Id., at 1329 . This requirement is satisfied even though the steps are actually undertaken by multiple parties, the court explained, if a single defendant "exercises 'control or direction' over the entire process such that every step is attributable to the controlling party." Ibid. The court held that the defendant in Muniauction was not liable for direct infringement because it did not exercise control or direction over its customers' performance of those steps of the patent that the defendant itself did not perform. Id., at 1330 .
In light of Muniauction, Limelight moved for reconsideration of its earlier motion for judgment as a matter of law, which the District Court had denied. The District Court granted the motion, concluding that Muniauction precluded a finding of direct infringement under § 271(a) because infringement of the '703 patent required tagging and Limelight does not control or direct its customers' tagging. A panel of the Federal Circuit affirmed, explaining that a defendant that does not itself undertake all of a patent's steps can be liable for direct infringement only "when there is an agency relationship between the parties who perform the method steps or when one party is contractually obligated to the
The Federal Circuit granted en banc review and reversed. The en banc court found it unnecessary to revisit its § 271(a) direct infringement case law. Instead, it concluded that the "evidence could support a judgment in [respondents'] favor on a theory of induced infringement" under § 271(b). 692 F.3d 1301 , 1319 (2012) ( per curiam ). This was true, the court explained, because § 271(b) liability arises when a defendant carries out some steps constituting a method patent and encourages others to carry out the remaining steps-even if no one would be liable as a direct infringer in such circumstances, because those who performed the remaining steps did not act as agents of, or under the direction or control of, the defendant. The Court of Appeals did not dispute that "there can be no indirect infringement without direct infringement," id., at 1308 , but it explained that "[r]equiring proof that there has been direct infringement ... is not the same as requiring proof that a single party would be liable as a direct
2 The panel noted that Limelight's contracts instruct its customers to tag the components they wish to be stored on Limelight's CDN, but concluded that, because these contracts did not give Limelight control over its customers, the customers' tagging could not be attributed to Limelight. See 629 F.3d, at 1321 .
One might think that this simple truth is enough to dispose of this appeal. But the Federal Circuit reasoned that a defendant can be liable for inducing infringement under § 271(b) even if no one has committed direct infringement within the terms of § 271(a) (or any other provision of the patent laws), because direct infringement can exist independently of a violation of these statutory provisions. See 692 F.3d, at 1314 .
The Federal Circuit's analysis fundamentally misunderstands what it means to infringe a method patent. A method patent claims a number of steps; under this Court's case law, the patent is not infringed unless all the steps are carried out. See, e.g., Aro, supra, at 344, 81 S.Ct. 599 (a "patent covers only the totality of the elements in the claim and ... no element, separately viewed, is within the grant"). This principle follows ineluctably from what a patent is: the conferral of rights in a particular claimed set of elements. "Each element contained in a patent claim is deemed material to defining the scope of the patented invention," Warner-Jenkinson Co. v. Hilton Davis Chemical Co., 520 U.S. 17 , 29, 117 S.Ct. 1040 , 137 L.Ed.2d 146 (1997), and a patentee's rights extend only to the claimed combination of elements, and no further.
The Federal Circuit held in Muniauction that a method's steps have not all been performed as claimed by the patent unless they are all attributable to the same defendant, either
3 Aro addressed contributory infringement under § 271(c), rather than inducement of infringement under § 271(b), but we see no basis to distinguish for these purposes between the two, which after all spring from common stock. See Global-Tech Appliances, Inc. v. SEB S. A., 563 U.S. ----, ----, 131 S.Ct. 2060 , 2067-2068, 179 L.Ed.2d 1167 (2011).
The Federal Circuit's contrary view would deprive § 271(b) of ascertainable standards. If a defendant can be held liable under § 271(b) for inducing conduct that does not constitute infringement, then how can a court assess when a patent holder's rights have been invaded? What
The Federal Circuit seems to have adopted the view that Limelight induced infringement on the theory that the steps that Limelight and its customers perform would infringe the '703 patent if all the steps were performed by the same person. But we have already rejected the notion that conduct which would be infringing in altered circumstances can form the basis for contributory infringement, and we see no reason to apply a different rule for inducement. In Deepsouth Packing Co. v. Laitram Corp., 406 U.S. 518 , 92 S.Ct. 1700 , 32 L.Ed.2d 273 (1972), a manufacturer produced components of a patented machine and then exported those components overseas to be assembled by its foreign customers.[4] (The assembly by the foreign customers did not violate U.S. patent laws.) In both Deepsouth and this case, the conduct that the defendant induced or contributed to would have been infringing if committed in altered circumstances: in Deepsouth if the machines had been assembled in the United States, see id., at 526 , 92 S.Ct. 1700 , and in this case if performance of all of the claimed steps had been attributable to the same person. In Deepsouth, we rejected the possibility of contributory infringement because the machines had not been assembled in the United States, and direct infringement had consequently never occurred. See id., at 526-527 , 92 S.Ct. 1700 . Similarly, in this case, performance of all the claimed steps cannot be attributed to a single person, so direct infringement never occurred. Limelight cannot be liable for inducing infringement that never came to pass.
B
Respondents' arguments in support of the Federal Circuit's reading of the statute are unpersuasive. First, respondents
4 Section 271(f) now prohibits the exporter's conduct at issue in Deepsouth .
Third, respondents contend that patent law principles established before the enactment of the Patent Act demonstrate that a defendant that performs some steps of a patent with the purpose of having its customers perform the remaining steps is liable for inducing infringement. But here, too, the nature of the rights created by the Patent Act defeats the notion that Congress could have intended to permit inducement liability where there is no underlying direct infringement. According to respondents, their understanding of the pre-1952 doctrine casts doubt on the Muniauction rule for direct infringement under § 271(a), on the ground that that rule has the indirect effect of preventing inducement liability where Congress would have wanted it. But the possibility that the Federal Circuit erred by too narrowly circumscribing the scope of § 271(a) is no reason for this Court to err a second time by misconstruing § 271(b) to impose liability for inducing infringement where no infringement has occurred.

IV
Respondents ask us to review the merits of the Federal Circuit's Muniauction rule for direct infringement under § 271(a). We decline to do so today.
In the first place, the question presented is clearly focused on § 271(b), not § 271(a). We granted certiorari on the following question: "Whether the Federal Circuit erred in holding that a defendant may be held liable for inducing patent infringement under 35 U.S.C. § 271 (b) even though no one has committed direct infringement under § 271(a)." Pet. for Cert. i. The question presupposes that Limelight has not committed direct infringement under § 271(a). And since the question on which we granted certiorari did not involve § 271(a), petitioner did not address that important issue in its opening brief. Our decision on the § 271(b) question necessitates a remand to the Federal Circuit, and on remand, the Federal Circuit will have the opportunity to revisit the § 271(a) question if it so chooses.
The judgment below is reversed, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
Limelight sought certiorari, which we granted. 571 U.S. ----, 187 L.Ed.2d 701 , 134 S.Ct. 895 (2014).

Neither the Federal Circuit, see 692 F.3d, at 1308 , nor respondents, see Tr. of Oral Arg. 44, dispute the proposition
Section 271(f)(1) reinforces our reading of § 271(b). That subsection imposes liability on a party who "supplies or causes to be supplied in or from the United States all or a substantial portion of the components of a patented invention ... in such manner as to actively induce the combination of such components outside of the United States in a manner that would infringe the patent if such combination occurred within the United States " (emphasis added). As this provision illustrates, when Congress wishes to impose liability for
In a related argument, respondents contend that, at tort, liability sometimes attaches where two or more defendants inflict injury, even if each defendant's conduct, standing alone, would not be actionable. See W. Keeton, D. Dobbs, R. Keeton, & D. Owen, Prosser and Keeton on Torts § 52, p. 354 (5th ed. 1984) (multiple defendants who each add negligible impurities to stream liable if aggregate impurities cause harm). But the rationale for imposing liability in these circumstances is that the defendants collectively invaded the plaintiff's protected interests. See ibid. By contrast, under the Muniauction rule, respondents' interests in the '713 patent have not been invaded.
Second, respondents seek to analogize § 271(b) to the federal aiding and abetting statute, 18 U.S.C. § 2 , and they argue that two parties who divide all the necessary elements of a crime between them are both guilty under § 2. The
