Limelight Networks, Inc. v. Akamai Techs, Inc., 572 U.S. ___ (2014)
Akamai is the exclusive licensee of a patent that claims a method of delivering electronic data using a content delivery network (CDN). Limelight also operates a CDN and carries out several of the steps claimed in the patent, but its customers, rather than Limelight itself, perform a step of the patent known as “tagging.” Under Federal Circuit case law, liability for direct infringement under 35 U.S.C. 271(a) requires performance of all steps of a method patent to be attributable to a single party. The district court concluded that Limelight could not have directly infringed the patent at issue because performance of the tagging step could not be attributed to it. The en banc Federal Circuit reversed, holding that a defendant who performed some steps of a method patent and encouraged others to perform the rest could be liable for inducement of infringement even if no one was liable for direct infringement. The Supreme Court reversed. A defendant is not liable for inducing infringement under section 271(b) when no one has directly infringed. The Federal Circuit’s contrary view would deprive section 271(b) of ascertainable standards and require the courts to develop parallel bodies of infringement law. Citing section 271(f), the Court stated that Congress knows how to impose inducement liability predicated on noninfringing conduct when it wishes to do so. Though a would-be infringer could evade liability by dividing performance of a method patent’s steps with another whose conduct cannot be attributed to the defendant, a desire to avoid this consequence does not justify fundamentally altering the rules of inducement liability clearly required by the Patent Act’s text and structure.

SUPREME COURT OF THE UNITED STATES
LIMELIGHT NETWORKS, INC. v. AKAMAI TECHNOLOGIES, INC., et al.
certiorari to the united states court of appeals for the federal circuit
No. 12–786. Argued April 30, 2014—Decided June 2, 2014
Akamai Technologies, Inc., a respondent here, is the exclusive licensee of a patent that claims a method of delivering electronic data using a content delivery network (CDN). Petitioner, Limelight Networks, Inc., also operates a CDN and carries out several of the steps claimed in the patent, but its customers, rather than Limelight itself, perform a step of the patent known as “tagging.” Under Federal Circuit case law, liability for direct infringement under 35 U. S. C. §271(a) requires performance of all steps of a method patent to be attributable to a single party. This position was most recently refined in Muniauction, Inc. v. Thomson Corp., 532 F. 3d 1318. The District Court concluded that Limelight could not have directly infringed the patent at issue because performance of the tagging step could not be attributed to it. The en banc Federal Circuit reversed, holding that a defendant who performed some steps of a method patent and encouraged others to perform the rest could be liable for inducement of infringement even if no one was liable for direct infringement. The en banc court concluded that the evidence could support liability for Limelight on an inducement theory and remanded for further proceedings.
Held: A defendant is not liable for inducing infringement under §271(b) when no one has directly infringed under §271(a) or any other statutory provision. Pp. 4–11.
(a) Liability for inducement must be predicated on direct infringement. Aro Mfg. Co. v. Convertible Top Replacement Co., 365 U. S. 336 . Assuming that Muniauction’s holding is correct, respondents’ method has not been infringed because the performance of all of its steps is not attributable to any one person. Since direct infringe-ment has not occurred, there can be no inducement of infringement under §271(b). The Federal Circuit’s contrary view would deprive §271(b) of ascertainable standards and require the courts to develop two parallel bodies of infringement law. This Court’s reading of §271(b) is reinforced by §271(f)(1), which illustrates that Congress knows how to impose inducement liability predicated on non-infringing conduct when it wishes to do so. The notion that conduct which would be infringing in altered circumstances can form the basis for contributory infringement has been rejected, see Deepsouth Packing Co. v. Laitram Corp., 406 U. S. 518 –527, and there is no reason to apply a different rule for inducement. Pp. 4–7.
(b) Respondents claim that principles from tort law and criminal aiding and abetting doctrine, as well as patent law principles in existence before the 1952 Patent Act, support the Federal Circuit’s reading of the statute, but their arguments are unpersuasive. Though a would-be infringer could evade liability by dividing performance of a method patent’s steps with another whose conduct cannot be attributed to the defendant, this is merely a result of the Federal Circuit’s interpretation of §271(a), and a desire to avoid this consequence does not justify fundamentally altering the rules of inducement liability clearly required by the Patent Act’s text and structure. Pp. 8–10.
(c) Because the question presented here is clearly focused on §271(b) and presupposes that Limelight has not committed direct infringement under §271(a), the Court declines to address whether the Federal Circuit’s decision in Muniauction is correct. P. 10.
692 F. 3d 1301, reversed and remanded.
Alito, J., delivered the opinion for a unanimous Court.

SUPREME COURT OF THE UNITED STATES
LIMELIGHT NETWORKS, INC., PETITIONER v. AKAMAI TECHNOLOGIES, INC., et al.
on writ of certiorari to the united states court of appeals for the federal circuit
[June 2, 2014]
Justice Alito delivered the opinion of the Court.
This case presents the question whether a defendant may be liable for inducing infringement of a patent under 35 U. S. C. §271(b) when no one has directly infringed the patent under §271(a) or any other statutory provision. The statutory text and structure and our prior case law require that we answer this question in the negative. We accordingly reverse the Federal Circuit, which reached the opposite conclusion.
Respondent the Massachusetts Institute of Technology is the assignee of U. S. Patent No. 6,108,703 (’703 patent), which claims a method of delivering electronic data using a “content delivery network,” or “CDN.” Respondent Akamai Technologies, Inc., is the exclusive licensee. Akamai maintains many servers distributed in various locations. Proprietors of Web sites, known as “content providers,” contract with Akamai to deliver their Web sites’ content to individual Internet users. The ’703 patent provides for the designation of certain components of a content provider’s Web site (often large files, such as video or music files) to be stored on Akamai’s servers and accessed from those servers by Internet users. The process of designating components to be stored on Akamai’s servers is known as “tagging.” By “aggregat[ing] the data demands of multiple content providers with differing peak usage patterns and serv[ing] that content from multiple servers in multiple locations,” 614 F. Supp. 2d 90, 96 (Mass. 2009), as well as by delivering content from servers located in the same geographic area as the users who are attempting to access it, Akamai is able to increase the speed with which Internet users access the content of its customers’ Web sites.
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. Respondents claim that Limelight “provides instructions and offers technical assistance” to its customers regarding how to tag, 629 F. 3d 1311, 1321 (CA 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 District of Massachusetts, claiming patent infringement. The case was tried to a jury, which found that Limelight had committed infringement and awarded more than $40 million in damages.
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 other to perform the steps.” 629 F. 3d, at 1320. Since neither of these conditions was met in the present case, the Federal Circuit panel held that Limelight could not be held liable for direct infringement. Ibid.
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 infringer,” id., at 1308–1309 (emphasis deleted). Judge Newman and Judge Linn both dissented (with the latter joined by Judges Dyk, Prost, and O’Malley).
Limelight sought certiorari, which we granted. 571 U. S. ___ (2014).
Neither the Federal Circuit, see 692 F. 3d, at 1308, nor respondents, see Tr. of Oral Arg. 44, dispute the proposition that liability for inducement must be predicated on direct infringement. This is for good reason, as our case law leaves no doubt that inducement liability may arise “if, but only if, [there is] . . . direct infringement.” Aro Mfg. Co. v. Convertible Top Replacement Co., 365 U. S 336, 341 (1961) (emphasis deleted).
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 (a “pat-ent 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 (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 de-fendant, either because the defendant actually performed those steps or because he directed or controlled others who performed them. See 532 F. 3d, at 1329–1330. Assuming without deciding that the Federal Circuit’s holding in Muniauction is correct, there has simply been no infringement of the method in which respondents have staked out an interest, because the performance of all the patent’s steps is not attributable to any one person. And, as both the Federal Circuit and respondents admit, where there has been no direct infringement, there can be no inducement of infringement under §271(b).
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 if a defendant pays another to perform just one step of a 12-step process, and no one performs the other steps, but that one step can be viewed as the most important step in the process? In that case the defendant has not encouraged infringement, but no principled reason prevents him from being held liable for inducement under the Federal Circuit’s reasoning, which permits inducement liability when fewer than all of a method’s steps have been performed within the meaning of the patent. The decision below would require the courts to develop two parallel bodies of infringement law: one for liability for direct infringement, and one for liability for inducement.
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 inducing activity that does not itself constitute direct infringement, it knows precisely how to do so. The courts should not create liability for inducement of non-infringing conduct where Congress has elected not to extend that concept.
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 (1972) , a manufacturer produced components of a patented machine and then exported those components overseas to be assembled by its foreign customers. (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, 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. 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.
Respondents’ arguments in support of the Federal Circuit’s reading of the statute are unpersuasive. First, respondents note that tort law imposes liability on a defendant who harms another through a third party, even if that third party would not himself be liable, and respondents contend that, given the background tort principles against which the Patent Act of 1952 was enacted, it should not matter that no one is liable for direct infringement in this case. But the reason Limelight could not have induced infringement under §271(b) is not that no third party is liable for direct infringement; the problem, instead, is that no direct infringement was committed. Muniauction (which, again, we assume to be correct) instructs that a method patent is not directly infringed—and the patentee’s interest is thus not violated—unless a single actor can be held responsible for the performance of all steps of the patent. Because Limelight did not undertake all steps of the ’703 patent and cannot otherwise be held responsible for all those steps, respondents’ rights have not been violated. Unsurprisingly, respondents point us to no tort case in which liability was imposed because a defendant caused an innocent third party to undertake action that did not violate the plaintiff’s legal rights.
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 analogy does not hold up. The aiding and abetting statute must be read “against its common-law background,” Standefer v. United States, 447 U. S. 10, 19 (1980) , and at common law two or more defendants, each of whom committed an element of a crime, were liable as principals. See, e.g., 1 J. Bishop, Commentaries on the Criminal Law §649, p. 392 (7th ed. 1882). While we have drawn on criminal law concepts in the past in interpreting §271(b), see Global-Tech Appliances, Inc. v. SEB S. A., 563 U. S. ___, ___ (2011) (slip op., at 10–12), we think it unlikely that Congress had this particular doctrine in mind when it enacted the Patent Act of 1952, given the doctrine’s inconsistency with the Act’s cornerstone principle that patentees have a right only to the set of elements claimed in their patents and nothing further.
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 Pat-ent Act defeats the notion that Congress could haveintended 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.
Finally, respondents, like the Federal Circuit, criticize our interpretation of §271(b) as permitting a would-be infringer to evade liability by dividing performance of a method patent’s steps with another whom the defendant neither directs nor controls. We acknowledge this concern. Any such anomaly, however, would result from the Fed-eral Circuit’s interpretation of §271(a) in Muniauction. A desire to avoid Muniauction’s natural consequences does not justify fundamentally altering the rules of inducement liability that the text and structure of the Patent Act clearly require—an alteration that would result in its own serious and problematic consequences, namely, creating for §271(b) purposes some free-floating concept of “infringement” both untethered to the statutory text and difficult for the lower courts to apply consistently.
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.
