'''Encyclopaedia Britannica v. Perplexity AI''' is a copyright and trademark action filed by Britannica and Merriam-Webster in the Southern District of New York on September 10, 2025.<ref name="docket" />

== September 2, 2026 discovery order ==
Magistrate Judge Sarah L. Cave partly granted the publishers’ request for additional retrieval-augmented generation (RAG) and user activity log (UAL) data. Perplexity must produce one additional RAG snapshot, with its date or period to be agreed through discussions, and host August 2025–January 2026 UAL data for inspection. The publishers must contribute $6,000 per month toward UAL hosting. The court balanced relevance against production burdens; this was a discovery ruling, not a determination of infringement.<ref name="order114" />

== September 9, 2026 discovery order ==
Following the September 8 conference, Magistrate Judge Sarah L. Cave required responses concerning source code and data questions by September 11, with remaining data answers due September 18. A joint revised case-management plan is due September 15. The order records Perplexity’s intended September 18 Discord production, requires a September 25 discovery-status letter, and schedules a September 29 conference. These dates do not establish that production occurred or resolve infringement liability.<ref name="order116" />
