Master Ninth Circuit adopted the server test, held Google's thumbnails were likely fair use, limited direct-liability exposure for inline linking, and remanded contributory infringement issues. with this comprehensive case brief.
Perfect 10 v. Amazon.com is a seminal Ninth Circuit decision at the intersection of copyright law and internet functionality. The case confronts how traditional exclusive rights—reproduction, distribution, and display—apply to search engines and websites that index, cache, embed, and link to images hosted by others. By articulating the "server test" for direct display liability and extending fair use protection to search-engine thumbnails, the court provided a durable framework for evaluating platform conduct that facilitates access to online images.
Beyond resolving the immediate dispute among Perfect 10, Google, and Amazon's A9 search engine, the decision reshaped the liability landscape for online intermediaries. It clarified that embedding or inline linking does not, by itself, constitute direct infringement of the display right when the content is not stored on the defendant's server, while leaving room for secondary liability where a service has knowledge of specific infringements and materially contributes to users' access to them. For law students, the case is a foundation for understanding fair use in search technology and the contours of direct, contributory, and vicarious liability online.
508 F.3d 1146 (9th Cir. 2007)
Perfect 10, a publisher of adult images, owned copyrights in photographs of its models and licensed certain small images for cell phone downloads through a partner (Fonestarz). Numerous third-party websites posted Perfect 10's images without authorization. Google's web crawler indexed those pages and, through Google Image Search, stored reduced-size copies (thumbnails) of images on Google's servers. Search results displayed grids of these thumbnails; when a user clicked a thumbnail, Google's result page used inline linking and framing so the user's browser retrieved and displayed the full-size image directly from the third-party site, not from Google's servers. Amazon subsidiary A9.com offered an image search service that relied on Google's search technology and similarly displayed thumbnails and linked to full-size images hosted by third parties. Perfect 10 sent notices identifying infringing URLs and sued Google and Amazon for copyright infringement, seeking a preliminary injunction. The district court granted a preliminary injunction against Google's display of thumbnails (finding no fair use) but denied relief as to inline linking and framing of full-size images; it denied or limited relief as to Amazon. All parties appealed, resulting in the Ninth Circuit's consolidated opinion.
1) Does a search engine directly infringe the display or distribution rights by inline linking or framing full-size images that reside on third-party servers? 2) Does a search engine's copying and display of thumbnail images constitute direct infringement, and if so, is it protected by fair use? 3) Can the search engine or related service be secondarily liable (contributory or vicarious) for facilitating user access to infringing images hosted by others?
Direct infringement of the display right under 17 U.S.C. § 106(5) requires that the defendant show a copy of the work, and a "copy" is a material object in which the work is fixed, 17 U.S.C. § 101. Under the Ninth Circuit's "server test," a service provider directly displays a work only if it stores and serves a copy of the work from its own server. Inline linking or framing content stored on another's server is not direct display infringement and does not distribute the work under § 106(3) because the defendant does not fix or disseminate a copy. Copying and displaying thumbnail images stored on the defendant's servers can implicate the reproduction and display rights, but such use may be fair use under § 107. Fair use requires analysis of four factors: (1) purpose and character of the use (including whether the use is transformative and commercial), (2) nature of the copyrighted work, (3) amount and substantiality used, and (4) market effect. Secondary liability: Contributory infringement arises where a defendant, with knowledge of the infringing activity, materially contributes to or induces the infringement (MGM v. Grokster; A&M Records v. Napster). Vicarious infringement requires a direct financial benefit from infringement and the right and ability to supervise or control the infringing conduct.
1) Inline linking and framing of full-size images that reside on third-party servers do not constitute direct infringement of the display or distribution rights under the server test. 2) Google's creation and display of thumbnail images stored on its servers implicates the reproduction and display rights but is likely fair use. 3) Perfect 10 did not show a likelihood of success on vicarious infringement because Google and Amazon lacked the right and ability to control the infringing activities of third-party websites. 4) Contributory infringement remains possible: providing links that facilitate access to known infringing images can materially contribute to infringement; the court remanded for further proceedings on contributory liability consistent with its standards.
Direct infringement and the server test: The court examined the statutory text defining a "display" as showing a copy of a work and a "copy" as a material object in which a work is fixed. Because full-size images appeared on users' screens by being transmitted from the third-party host's server to the user's browser, and not from Google's or Amazon's servers, neither Google nor Amazon possessed or served the fixed copies of those full-size images. Inline linking and framing merely directed the user's browser to retrieve content from another source; thus, the search engines did not directly infringe the display or distribution rights with respect to full-size images. This analysis also meant there was no direct distribution, as no copies were transferred by Google or Amazon. Thumbnails and fair use: By contrast, Google stored and served reduced-size thumbnail versions of images on its own servers, implicating reproduction and display rights. Applying § 107, the court found Google's use highly transformative: the thumbnails served a new and different function—improving access to and organization of information—rather than supplanting the original expressive purpose. Although Google's use was commercial, transformative character weighed strongly in favor of fair use, consistent with Kelly v. Arriba Soft. The works were creative, which modestly weighed against fair use. Google used entire images, but that was reasonable and necessary for image search functionality and therefore did not weigh heavily against fair use. On market effect, Perfect 10 argued Google's thumbnails harmed its cell-phone thumbnail licensing market (via Fonestarz). The court found the evidence of market substitution weak and attenuated; the thumbnails' role as search tools did not reasonably supplant a market for licensed downloads, and any harm from full-size images stemmed from third-party infringement, not Google's thumbnails. Balancing the factors, the court concluded Google's thumbnail use was likely fair use. Secondary liability: For contributory infringement, the court restated that liability attaches where a defendant, with knowledge of specific infringement, materially contributes to it. A search engine can materially contribute by providing links that facilitate user access to infringing images if it knows of the infringing activity and fails to take reasonable steps to limit such access. The record suggested Google and Amazon received notices identifying infringing URLs. The district court's analysis did not fully apply the proper standard, so the Ninth Circuit remanded for reconsideration of contributory liability in light of the knowledge and material contribution framework. For vicarious infringement, Perfect 10 failed to show that Google or Amazon had the right and ability to control the infringing conduct of third-party websites that hosted images; the ability to remove links from search results is not the same as controlling the infringing activity itself. Nor was there sufficient evidence of a direct financial benefit tied to specific infringements to establish vicarious liability at the preliminary injunction stage. Procedurally, because this was an appeal from preliminary injunction rulings, the Ninth Circuit focused on likelihood of success on the merits and applied its holdings to both Google and Amazon's A9 service, which relied on Google's image search results.
Perfect 10 v. Amazon.com is a cornerstone of internet copyright law. It established the server test for direct display liability, a rule widely applied to determine whether embedding or inline linking constitutes direct infringement. It confirmed that search-engine thumbnails can be protected by fair use due to their transformative, informational function, extending and reinforcing Kelly v. Arriba Soft. The decision also delineates the boundary between direct and secondary liability for online intermediaries: while mere linking does not make a service a direct infringer, knowledge-plus-material-contribution can give rise to contributory liability. For law students, the case is indispensable for understanding platform liability, fair use in functional technologies, and the doctrinal architecture that governs how the web works.
The server test holds that a website directly displays a copyrighted image under § 106(5) only if it stores and serves a copy of the image from its own server. If the site merely embeds, frames, or inline links to an image hosted on a third-party server, it does not directly infringe the display or distribution rights because it does not fix or transmit a copy.
The court deemed the thumbnails highly transformative: they converted full-sized creative works into low-resolution search tools that facilitate locating information. Although Google's use was commercial and it used the entire image, those factors carried less weight given the functional necessity for image search. Evidence of market substitution for Perfect 10's cell-phone thumbnails was weak, and any market harm primarily flowed from third-party full-size infringements rather than the thumbnails themselves.
Embedding or framing, by itself, is not direct infringement of the display or distribution rights under the server test if the content is not stored on the embedding site's servers. However, embedding can support contributory infringement if the site knows of specific infringements and materially contributes by facilitating access without taking reasonable steps in response. Other legal regimes (e.g., DMCA safe harbors, trademark, or publicity laws) may also be relevant depending on the facts.
Perfect 10 builds on Kelly by reaffirming that search-engine thumbnails are likely fair use due to their transformative purpose. It goes further by articulating the server test for direct display liability and by providing a more detailed roadmap for assessing contributory and vicarious infringement in the context of image search and linking.
No. The court held Perfect 10 was unlikely to succeed on a vicarious infringement theory because Google and Amazon lacked the right and ability to control the infringing conduct of the third-party websites that hosted the images. Removing links from search results is not equivalent to controlling the underlying infringement.
The Ninth Circuit held that contributory liability was legally plausible where a service has knowledge of specific infringing activity and materially contributes by providing links that facilitate access. It remanded for the district court to apply the correct standards to the evidentiary record, including the effect of notices identifying infringing URLs and the providers' responses.
Perfect 10 v. Amazon.com reconciles copyright doctrine with the technical realities of the web. By adopting the server test, it shields routine web architecture—embedding and linking—from direct display liability while recognizing that copying to create and serve thumbnails triggers fair use analysis that favors search functionality. At the same time, the court preserved the possibility of secondary liability where a service meaningfully facilitates access to known infringements.
For practitioners and students, the decision is a doctrinal anchor in assessing platform risk: it distinguishes direct from secondary infringement, clarifies fair use in the search context, and underscores that knowledge and material contribution can convert passive linking into actionable contributory infringement. Its framework remains central to evaluating how internet intermediaries curate and present content today.
