MDL
Tremblay v. OpenAI
MDL ConsolidatedClass claims present
Tremblay, et al. v. OpenAI, Inc., et al. (In re OpenAI ChatGPT Litigation)
Where it stands
Originally the N.D. Cal. 'In re OpenAI ChatGPT Litigation' (consolidating Tremblay, Silverman and Chabon), it was transferred to S.D.N.Y. and centralized in MDL 3143 in April 2025, where it is in coordinated discovery.
Key ruling
Feb. 12, 2024 (N.D. Cal., pre-transfer) — Judge Martínez-Olguín dismissed most of the derivative-output, DMCA and unjust-enrichment theories while allowing the direct infringement claim to proceed.
What is not confirmed
The Silverman line of cases was folded into this consolidated proceeding; the 2024 N.D. Cal. dismissal ruling was reported contemporaneously but I did not re-verify its exact date against the docket in this research pass.The record
