9 Plaintiffs, ORDER GRANTING MOTION FOR SUMMARY JUDGMENT 10 v.

11 PINTEREST, INC., Re: Dkt. No. 109 Defendant. 12

13 Defendant Pinterest, Inc., (“Pinterest”) moves for summary judgment in this copyright 14 infringement suit brought by Plaintiff Maureen Harrington as a representative of Blaine 15 Harrington III’s estate (collectively, “Harrington”). Def. Pinterest, Inc.’s Notice of Mot. & Mot. 16 for Summ. J. (“Mot.”), ECF No. 109. The motion has been fully briefed. Pl.’s Mem. of P. & A. 17 in Opp’n to Def.’s Mot. for Summ. J. (“Opp’n”), ECF No. 116; Pinterest, Inc.’s Reply in Supp. of 18 Mot. for Summ. J. (“Reply”), ECF No. 120. 19 Upon careful review of the relevant documents, the Court finds this matter suitable for 20 decision without oral argument pursuant to Local Rule 7-1(b). For the reasons discussed below, 21 the Court GRANTS Pinterest’s motion for summary judgment. 22 I. BACKGROUND 23 After a series of motions to dismiss, Harrington now brings one cause of action for direct 24 copyright infringement on behalf of himself and a class of other professional photographers whose 25 federally registered copyrighted works were publicly displayed by Pinterest in notifications 26 outside of its website. 3d Am. Class Action Compl. ¶¶ 49, 59–67 (“TAC”), ECF No. 88. 27 A. Pinterest’s Platform 1 Pinterest operates one of the largest social media platforms in the world. Id. ¶¶ 1, 17. The 2 aggregate monthly users of Pinterest’s websites and mobile applications (collectively, its 3 “platform”) number in the hundreds of millions. Id. ¶¶ 1, 18. Pinterest’s platform allows users to 4 upload content in the form of a “Pin” and share that content with other Pinterest users. Decl. of 5 Nicholas DeChant in Supp. of Def. Pinterest, Inc.’s Mot. for Summ. J., dated December 9, 2021, 6 ¶¶ 2–3, 7 (“DeChant Decl. I”), ECF No. 109-12. A Pin operates as a “visual bookmark” and 7 consists of the user-uploaded content (typically an image), a user-created title and description, and 8 a hyperlink to a third-party website. Id. ¶¶ 2, 5, 7; Decl. of Henry Lien in Supp. of Def. Pinterest, 9 Inc.’s Mot. for Summ. J. ¶ 5 (“Lien Decl.”), ECF No. 109-11. When a user uploads content to the 10 company’s platform, Pinterest’s system automatically standardizes its file format and other 11 specifications. Id. ¶ 8. For images, Pinterest also generates and stores several different sizes of 12 the uploaded content, known as “variants.” Id. ¶¶ 9–10. Variants allow Pinterest to efficiently 13 display uploaded content to its users across many types of devices. Id. ¶ 9. 14 Pinterest displays a custom series of user-uploaded Pins to individual users via “feeds”— 15 grids of Pins curated by machine learning algorithms and calculated to be interesting to individual 16 users. Id. ¶¶ 12–13. Pinterest further intersperses feeds on its platform with paid advertisements 17 that visually appear similar to user-uploaded Pins and are labeled as “promoted.” Id. ¶ 17; see 18 DeChant Decl. I Exs. 1–2, 4 (screenshots of feeds on Pinterest’s platform). Pinterest displays 19 these feeds to users in many forms across its platform. DeChant Decl. I ¶¶ 12–18 (describing 20 feeds on Pinterest’s homepage, feeds displayed when viewing individual Pins, and feeds displayed 21 as search results). 22 B. Alleged Infringing Notifications 23 Of particular relevance here, Pinterest also displays feeds to users in notifications. TAC ¶ 24 24; DeChant Decl. I ¶ 18. These notifications come in several forms, including emails, in-app 25 notifications, and mobile push notifications. TAC ¶ 24; DeChant Decl. I ¶ 18. Notifications 26 contain hyperlinks that correspond to an image on Pinterest’s platform. TAC ¶ 24; DeChant Decl. 27 1 I ¶ 18; Dep. of Kevin Kim 40:2–42:4, 44:7–12 (“Kim Dep.”), ECF No. 109-2. Typically, upon 2 receiving a notification containing a hyperlink, user-side software—that is, the user’s email 3 program, web browser, operating system, etc.—will read the hyperlink, access the corresponding 4 image on Pinterest’s server, then display that image to the user. Kim Dep. 42:21–43:10; Decl. of 5 Nicholas DeChant in Supp. of Def. Pinterest, Inc.’s Mot. for Summ. J., dated March 31, 2025, ¶¶ 6 5–6 (“DeChant Decl. II”), ECF No. 109-20. The parties dispute whether Pinterest’s notifications 7 also contain advertisements. Compare Decl. of Michael R. Reese in Supp. of Pl.’s Opp’n to 8 Def.’s Mot. for Summ. J., Ex. 15 (“Reese Decl.”), ECF No. 116-16 (displaying screenshots of 9 email notifications containing Pins with brand logos), with DeChant Decl. I ¶ 18 (“Notifications 10 do not contain advertisements.”). 11 On July 25, 2020, Pinterest sent one such email notification to Harrington that displayed an 12 image of Harrington’s own copyrighted photograph of a beach scene titled “Waikiki Beach, 13 Honolulu, Oahu, Hawaii, USA.” TAC ¶ 31. Harrington filed suit on July 31, 2020, approximately 14 six days later. Class Action Compl., ECF No. 1. 15 C. The Davis Action 16 Prior to Harrington initiating the current suit, a different professional photographer filed a 17 related action against Pinterest in the Northern District. See Davis v. Pinterest, Inc., 601 F.Supp. 18 3d 514, 517 (N.D. Cal. 2023) (“Davis I”). There, the plaintiff Davis alleged that Pinterest 19 infringed on his copyrighted photographs by displaying them in proximity to advertisements on 20 the platform. Id. at 529. Although Davis, similar to Harrington, also alleged infringement based 21 on notifications outside of the platform, the District Court found that Davis failed to timely 22 identify these instances of infringement. Id. at 527. Therefore, “instances of alleged infringement 23 from Pinterest’s notifications [were] not at issue” in the Davis action.1 Id. The court ultimately 24 found that Pinterest was entitled to safe harbor under Section 512(c) of the DMCA for works 25 displayed on its platform. Id. at 536. 26

27 1 Although, in dicta, the Davis court suggested that works displayed in notifications would not infringe Davis’s copyrights. Davis I, 601 F.Supp. 3d at 527. 1 The Ninth Circuit affirmed upon appeal, holding that: (1) “[t]he district court did not abuse 2 its discretion by refusing to consider undisclosed and untimely allegations of infringement,” and 3 (2) “Pinterest established that it is entitled to safe harbor protection” under Section 512(c). Davis 4 v. Pinterest, Inc., No. 22-15804, 2023 WL 5695992, at *1–2 (9th Cir. Sept. 5, 2023) (“Davis II”). 5 D. Procedural History 6 This case was stayed pending resolution of Davis I, then further stayed pending Ninth 7 Circuit’s decision in Davis II. ECF Nos. 66, 71. When the Court lifted its stay, Harrington 8 narrowed his infringement allegations to only notifications outside of Pinterest’s platform. Mot. 9 for Leave, ECF No. 82. Given the Ninth Circuit affirming the exclusion of allegations of 10 infringement outside of the platform in Davis II, the Court found Harrington’s new narrow claims 11 were not barred under the doctrine of res judicata. Order Granting Mot. for Leave, ECF No. 87. 12 Pinterest subsequently filed a motion to dismiss Harrington’s TAC arguing, in part, that 13 Pinterest’s conduct was protected under the DMCA safe-harbor provision per Davis II. Order 14 Granting in Part & Den. in Part Mot. to Dismiss, 5, 7 (“MTD Order”), ECF. No. 100; see Mot. to 15 Dismiss, ECF No. 92. The Court rejected this argument, reiterating that “the Ninth Circuit did not 16 examine instances of infringement outside of Pinterest’s platform” in Davis II. MTD Order at 7. 17 The Court also found resolution of this issue inappropriate in a motion to dismiss. Given that the 18 DMCA safe-harbor defense is a “fact intensive inquiry,” id. (citing Hunley v. Instagram, LLC, 73 19 F.4th 1060, 1072 (9th Cir.
