Background
Plaintiff Jane Doe filed a putative nationwide class action on behalf of her minor children and other children under 18 against OpenAI Foundation (formerly OpenAI Inc.) and related defendants. The complaint alleges that defendants' chatbot "coerces" children to share sensitive and highly personal details about themselves, including health information. Plaintiff moved to proceed under a pseudonym pursuant to the Ninth Circuit framework established in Does I through XXIII v. Advanced Textile Corp., 214 F.3d 1058 (9th Cir. 2000), arguing that requiring her to disclose her identity would effectively reveal her children's identities despite Rule 5.2(a)(3)'s protections for minors.
The motion was heard by United States Magistrate Judge Alex G. Tse in the Northern District of California. Plaintiff represented that defendants already possess the records at issue and that she is willing to disclose her and her children's identities under a protective order. The court evaluated the motion under the Advanced Textile factors, considering the sensitivity of the matter, potential prejudice to defendants, and the public interest in open proceedings.
The Court’s Holding
The court granted plaintiff's motion to proceed pseudonymously at this stage of litigation. The court concluded that the conversations about minors' health and personal information implicate a significant need to "preserve privacy in a matter of sensitive and highly personal nature" under Advanced Textile, 214 F.3d at 1068. Disclosing plaintiff's identity would allow her children's identities to be "readily surmised," citing Z.A. v. Lucile Salter Packard Children's Hosp. at Stanford, 840 F.Supp.3d 530, 540 (N.D. Cal. 2026).
The court found minimal prejudice to defendants because plaintiff represents that defendants already possess the relevant records and she has offered to disclose identities under a protective order. At this early stage, the burden of anonymity on defendants is "not weighty," citing In re Meta AI Glasses Litigation, 2026 WL 2718882, at *3 (N.D. Cal. Sept. 15, 2026). The public interest favors anonymity because plaintiff's identity is not critical to the working of justice and the basic facts will remain on public record, citing B.M. v. Wyndham Hotels & Resorts, Inc., 2020 WL 4368214, at *10 (N.D. Cal. July 30, 2020). The ruling is without prejudice to reconsideration at a later date.
Key Takeaways
- Courts in the Northern District of California will grant pseudonymous proceedings in cases involving minors' sensitive personal information where disclosure of a parent's identity would effectively reveal the children's identities.
- A defendant's possession of the underlying records and a plaintiff's willingness to disclose identity under a protective order significantly reduce prejudice arguments against pseudonymity.
- At the early stages of litigation, the burden of anonymity on defendants is considered minimal, particularly in putative class actions involving children's privacy.
- The public interest in open proceedings does not outweigh privacy interests when the plaintiff's identity is not critical to the case and basic facts remain public.
- Pseudonym rulings are explicitly made without prejudice to reconsideration as the case develops.
Why It Matters
This order reflects the Northern District of California's continued willingness to protect the identities of minor children in technology-related privacy litigation, particularly where AI chatbots are alleged to extract sensitive personal information. The decision aligns with a growing trend of courts recognizing the unique privacy vulnerabilities of children in digital interactions and the derivative exposure that occurs when a parent's identity is disclosed in litigation brought on a child's behalf.
The ruling also signals that defendants' possession of underlying data and the availability of protective orders will weigh heavily against prejudice arguments at the motion-to-dismiss stage. As AI-related class actions involving minors proliferate, this framework provides a template for pseudonymous practice that balances Ninth Circuit precedent with the practical realities of modern data possession.
