Opinion

MAUREEN HARRINGTON, et al., Case No. 5:20-cv-05290-EJD

Plaintiffs, ORDER GRANTING MOTION FOR SUMMARY JUDGMENT v.

PINTEREST, INC., Re: Dkt. No. 109 Defendant.

Defendant Pinterest, Inc., (“Pinterest”) moves for summary judgment in this copyright infringement suit brought by Plaintiff Maureen Harrington as a representative of Blaine Harrington III’s estate (collectively, “Harrington”). Def. Pinterest, Inc.’s Notice of Mot. & Mot. for Summ. J. (“Mot.”), ECF No. 109. The motion has been fully briefed. Pl.’s Mem. of P. & A. in Opp’n to Def.’s Mot. for Summ. J. (“Opp’n”), ECF No. 116; Pinterest, Inc.’s Reply in Supp. of Mot. for Summ. J. (“Reply”), ECF No. 120. Upon careful review of the relevant documents, the Court finds this matter suitable for decision without oral argument pursuant to Local Rule 7-1(b). For the reasons discussed below, the Court GRANTS Pinterest’s motion for summary judgment. After a series of motions to dismiss, Harrington now brings one cause of action for direct copyright infringement on behalf of himself and a class of other professional photographers whose federally registered copyrighted works were publicly displayed by Pinterest in notifications outside of its website. 3d Am. Class Action Compl. ¶¶ 49, 59–67 (“TAC”), ECF No. 88. A. Pinterest’s Platform Pinterest operates one of the largest social media platforms in the world. Id. ¶¶ 1, 17. The aggregate monthly users of Pinterest’s websites and mobile applications (collectively, its “platform”) number in the hundreds of millions. Id. ¶¶ 1, 18. Pinterest’s platform allows users to upload content in the form of a “Pin” and share that content with other Pinterest users. Decl. of Nicholas DeChant in Supp. of Def. Pinterest, Inc.’s Mot. for Summ. J., dated December 9, 2021, ¶¶ 2–3, 7 (“DeChant Decl. I”), ECF No. 109-12. A Pin operates as a “visual bookmark” and consists of the user-uploaded content (typically an image), a user-created title and description, and a hyperlink to a third-party website. Id. ¶¶ 2, 5, 7; Decl. of Henry Lien in Supp. of Def. Pinterest, Inc.’s Mot. for Summ. J. ¶ 5 (“Lien Decl.”), ECF No. 109-11. When a user uploads content to the company’s platform, Pinterest’s system automatically standardizes its file format and other specifications. Id. ¶ 8. For images, Pinterest also generates and stores several different sizes of the uploaded content, known as “variants.” Id. ¶¶ 9–10. Variants allow Pinterest to efficiently display uploaded content to its users across many types of devices. Id. ¶ 9. Pinterest displays a custom series of user-uploaded Pins to individual users via “feeds”— grids of Pins curated by machine learning algorithms and calculated to be interesting to individual users. Id. ¶¶ 12–13. Pinterest further intersperses feeds on its platform with paid advertisements that visually appear similar to user-uploaded Pins and are labeled as “promoted.” Id. ¶ 17; see DeChant Decl. I Exs. 1–2, 4 (screenshots of feeds on Pinterest’s platform). Pinterest displays these feeds to users in many forms across its platform. DeChant Decl. I ¶¶ 12–18 (describing feeds on Pinterest’s homepage, feeds displayed when viewing individual Pins, and feeds displayed as search results). B. Alleged Infringing Notifications Of particular relevance here, Pinterest also displays feeds to users in notifications. TAC ¶ 24; DeChant Decl. I ¶ 18. These notifications come in several forms, including emails, in-app notifications, and mobile push notifications. TAC ¶ 24; DeChant Decl. I ¶ 18. Notifications contain hyperlinks that correspond to an image on Pinterest’s platform. TAC ¶ 24; DeChant Decl. I ¶ 18; Dep. of Kevin Kim 40:2–42:4, 44:7–12 (“Kim Dep.”), ECF No. 109-2. Typically, upon receiving a notification containing a hyperlink, user-side software—that is, the user’s email program, web browser, operating system, etc.—will read the hyperlink, access the corresponding image on Pinterest’s server, then display that image to the user. Kim Dep. 42:21–43:10; Decl. of Nicholas DeChant in Supp. of Def. Pinterest, Inc.’s Mot. for Summ. J., dated March 31, 2025, ¶¶ 5–6 (“DeChant Decl. II”), ECF No. 109-20. The parties dispute whether Pinterest’s notifications also contain advertisements. Compare Decl. of Michael R. Reese in Supp. of Pl.’s Opp’n to Def.’s Mot. for Summ. J., Ex. 15 (“Reese Decl.”), ECF No. 116-16 (displaying screenshots of email notifications containing Pins with brand logos), with DeChant Decl. I ¶ 18 (“Notifications do not contain advertisements.”). On July 25, 2020, Pinterest sent one such email notification to Harrington that displayed an image of Harrington’s own copyrighted photograph of a beach scene titled “Waikiki Beach, Honolulu, Oahu, Hawaii, USA.” TAC ¶ 31. Harrington filed suit on July 31, 2020, approximately six days later. Class Action Compl., ECF No. 1. C. The Davis Action Prior to Harrington initiating the current suit, a different professional photographer filed a related action against Pinterest in the Northern District. See Davis v. Pinterest, Inc., 601 F.Supp. 3d 514, 517 (N.D. Cal. 2023) (“Davis I”). There, the plaintiff Davis alleged that Pinterest infringed on his copyrighted photographs by displaying them in proximity to advertisements on the platform. Id. at 529. Although Davis, similar to Harrington, also alleged infringement based on notifications outside of the platform, the District Court found that Davis failed to timely identify these instances of infringement. Id. at 527. Therefore, “instances of alleged infringement from Pinterest’s notifications [were] not at issue” in the Davis action.1 Id. The court ultimately found that Pinterest was entitled to safe harbor under Section 512(c) of the DMCA for works displayed on its platform. Id. at 536.
