 cache copying constitutes a fair use, Google has established a likelihood of success on this issue. Accordingly, Perfect 10 has not carried its burden of showing that users’ cache copies of Perfect 10’s full-size images constitute direct infringement.

Therefore, we must assess Perfect 10’s arguments that Google is secondarily liable in light of the direct infringement that is undisputed by the parties: third-party websites’ reproducing, displaying, and distributing unauthorized copies of Perfect 10’s images on the Internet. Id. at 852.
 * A.&ensp;Contributory Infringement

In order for Perfect 10 to show it will likely succeed in its contributory liability claim against Google, it must establish that Google’s activities meet the definition of contributory liability recently enunciated in Grokster. Within the general rule that “[o]ne infringes contributorily by intentionally inducing or encouraging direct infringement,” Grokster, 545 U.S. at 930, 125 S.Ct. 2764, the Court has defined two categories of contributory liability: “Liability under our jurisprudence may be predicated on actively encouraging (or inducing) infringement through specific acts (as the Court’s opinion develops) or on distributing a product distributees use to infringe copyrights, if the product is not capable of ‘substantial’ or ‘commercially significant’ noninfringing uses.” Id. at 942, 125 S.Ct. 2764 (Ginsburg, J., concurring) (quoting Sony, 464 U.S. at 442, 104 S.Ct. 774); see also id. at 936–37, 125 S.Ct. 2764.

Looking at the second category of liability identified by the Supreme Court (distributing products), Google relies on Sony, 464 U.S. at 442, 104 S.Ct. 774, to argue that it cannot be held liable for contributory infringement because liability does not arise from the mere sale of a product (even with knowledge that consumers would use the product to infringe) if the product is capable of substantial non-infringing use. Google argues that its search engine service is such a product. Assuming the principle enunciated in Sony is applicable to the operation of Google’s search engine, then Google cannot be held liable for contributory infringement solely because the design of its search engine facilitates such infringement. Grokster, 545 U.S. at 931–32, 125 S.Ct. 2764 (discussing Sony, 464 USS. 417, 104 S.Ct. 774, 78 L.Ed.2d 574). Nor can Google be held liable solely because it did not develop technology that would enable its search engine to automatically avoid infringing images. See id. at 939 n. 12, 125 S.Ct. 2764. However, Perfect 10 has not based its claim of infringement on the design of Google’s search engine and the Sony rule does not immunize Google from other sources of contributory liability. See id. at 933–34, 125 S.Ct. 2764.

We must next consider whether Google could be held liable under the first category of contributory liability identified by the Supreme Court, that is, the liability that may be imposed for intentionally encouraging infringement through specific acts. Grokster tells us that contribution to infringement must be intentional for liability to arise. Grokster, 545 U.S. at 930, 125 S.Ct. 2764. However, Grokster also directs us to analyze contributory liability in light of “rules of fault-based liability derived from the common law,” id. at 934–35, 125 S.Ct. 2764, and
