Opinion

UNITED STATES DISTRICT COURT SOUTHERN DISTRICT OF NEW YORK

IN RE:

25-md-3143 (SHS) (OTW) OPENAI, INC. COPYRIGHT INFRINGEMENT LITIGATION OPINION & ORDER

This Document Relates To: Ziff Davis et al. v. OpenAI et al., 25-cv-4315 SIDNEY H. STEIN, U.S. District Judge. OpenAI1 has moved to dismiss certain claims in Ziff Davis’s2 First Amended 0F 1F Complaint and to stay this action in part with respect to certain causes of action and models. (Dkt. Nos. 405 (Mot. to Dismiss), 134 (Mot. to Stay).) OpenAI’s motion to dismiss is granted with respect to claims 4 and 5, is granted in part and denied in part with respect to claim 8, and is denied with respect to claims 3, 6, and 7. OpenAI’s motion to stay is denied as to claim 7 and is moot as to claims 4 and 5 in light of the Court’s dismissal of those claims. OpenAI’s motion to stay is granted as to the models not already in this multidistrict litigation (“MDL”), namely, the o1, o1 mini, o1-pro, GPT-4.1, GPT-4.5, o3, o3-mini, o4-mini, and GPT-5 models. I. BACKGROUND All factual allegations in the First Amended Complaint (“FAC”) are assumed to be true for the purposes of OpenAI’s motion to dismiss. Faber v. Metro. Life Ins. Co., 648 F.3d 98, 104 (2d Cir. 2011). Ziff Davis has been a publisher of journalism for nearly 100 years and currently owns more than 45 digital media publications and internet brands, including IGN, Mashable, CNET, ZDNET, PCMag, Lifehacker, BabyCenter, and Everyday Health, which

1 Defendants OpenAI, Inc., OpenAI GP LLC, OpenAI, LLC, OpenAI OpCo LLC, OpenAI Global LLC, OAI Corporation, LLC, OpenAI Holdings, LLC, OpenAI Startup Fund I LP, OpenAI Startup Fund GP I LLC, and OpenAI Startup Fund Management LLC are referred to collectively as “OpenAI.” 2 Plaintiffs Ziff Davis, Inc., Ziff Davis, LLC, IGN Entertainment, Inc., Everyday Health Media, LLC, Mashable, Inc., and CNET Media, Inc. are referred to collectively as “Ziff Davis.” collectively produce nearly 2 million articles supported by rigorous research, reporting, and product testing annually. (Dkt. No. 300 (FAC) ¶¶ 2, 33, 39.) Ziff Davis’s portfolio focuses on content in “discrete and consumer-rich media ‘vertical’ categories” including Technology and Shopping, Gaming and Entertainment, and Health and Wellness. (Id. ¶ 35.) Ziff Davis’s digital media publications receive hundreds of millions of unique user visits per month and have won numerous publishing awards. (Id. ¶¶35–36.) Ziff Davis does not typically place its media content behind “paywalls” and instead generates revenue largely through advertising, content licensing, syndication, and commissions on products that users purchase via links in Ziff Davis’s product reviews. (Id. ¶¶ 47–48, 52, 196.) Ziff Davis owns federally registered trademarks associated with many of its brands, seven of which—MASHABLE, LIFEHACKER, CNET, ZDNET, PCMAG, BABYCENTER, and IGN—Ziff Davis asserts are famous (the “Ziff Davis Marks”). (Id. ¶¶ 55–57.) OpenAI is a technology company founded in December 2015 as a non-profit organization focused on artificial intelligence (“AI”) research and relaunched in March 2019 as a for-profit enterprise. (Id. ¶¶ 58, 61.) OpenAI develops large language models (“LLMs”), including its “Generative Pretrained Transformer” or “GPT” series of LLMs. (Id. ¶ 3.) When developing these LLMs, OpenAI compiles large datasets comprised of human-authored text such as articles, books, and scraped web data, copies these datasets into its storage systems, then uses these datasets to “train” its LLMs. (Id. ¶¶ 76– 79.) To train an LLM, OpenAI breaks the text of the gathered third-party content into “tokens,” which consist of words or portions of words. (Id. ¶ 79.) During training, some token are “masked” and the LLM attempts to predict what the masked token is. (Id. ¶ 80.) Over time, this process “trains” the LLM to predict more accurately the correct masked token, which ultimately allows the LLM to produce text resembling human- authored text. (Id. ¶ 80–83.) One consequence of the training process is that LLMs exhibit a behavior known as “memorization” where, when provided with the right prompt, an LLM can reproduce verbatim substantial portions of the materials that were used to train the LLM. (Id. ¶¶ 87–88.) OpenAI has created lucrative products using its LLMs, including its chatbots ChatGPT, ChatGPT Search, and ChatGPT Deep Research, and licenses its products to businesses that build their own offerings using OpenAI’s LLMs. (Id. ¶¶ 92, 96.) ChatGPT in particular has grown immensely in popularity since its launch, with 400 million weekly active users as of February 2025 and 800 million weekly active users by early April 2025. (Id. ¶ 94.) OpenAI used copyrighted works created and owned by Ziff Davis during its development and operation of its LLMs. (Id. ¶ 107.) OpenAI copied Ziff Davis’s works into its LLM training datasets using existing pools of scraped website content and by directly scaping content from Ziff Davis’s websites. (Id. ¶ 108.) These copies did not include copyright management information and were created by ChatGPT’s web- scraping tool, “GPTBot,” despite Ziff Davis’s inclusion of robots.txt files in its websites’ code, which allegedly instructed GPTBot not to scrape Ziff Davis’s websites. (Id. ¶¶ 109, 116–28.) The outputs of OpenAI’s LLMs sometimes include content drawn or copied from Ziff Davis’s copyrighted works, and OpenAI uses those outputs to further train its LLMs. (Id. ¶¶ 111–12.) Some outputs of OpenAI’s LLMs misleadingly or inaccurately attribute content to Ziff Davis. (Id. ¶¶ 174–77.) The First Amended Complaint asserts nine causes of action: (1) copyright infringement by OpenAI based on its use of Ziff Davis’s works to train OpenAI’s LLMs, (2) copyright infringement based on outputs of OpenAI’s LLMs, (3) contributory copyright infringement, (4) common law unjust enrichment, (5) circumvention of technological measures in violation of 17 U.S.C. § 1201(a)(1), (6) removal of copyright management information in violation of 17 U.S.C. § 1202(b)(1), (7) distribution of works with copyright management information removed in violation of 17 U.S.C. § 1202(b)(3), (8) trademark dilution, and (9) dilution and injury to business reputation in violation of Delaware state law. II. MOTION TO DISMISS OpenAI has moved to dismiss claims 3, 4, 5, 6, 7, and 8. The Court grants OpenAI’s motion to dismiss claims 4 and 5, grants in part and denies in part the motion to dismiss claim 8, and denies the motion to dismiss claims 3, 6, and 7. A. Motion to Dismiss Standard “To survive a motion to dismiss, a complaint must contain sufficient factual matter, accepted as true, to ‘state a claim to relief that is plausible on its face.’” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009) (quoting Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570 (2007)). When considering a Rule 12(b)(6) motion to dismiss, a court must “draw all reasonable inferences in Plaintiffs’ favor, assume all well-pleaded factual allegations to be true, and determine whether they plausibly give rise to an entitlement to relief.” Faber, 648 F.3d at 104 (internal quotations marks and citation omitted).
