The story
The Chicago Tribune’s copyright lawsuit against Perplexity AI has advanced to the discovery phase following a protective order filing in Illinois state court on October 21, 2026. The order, designated Doc #66 in case CL71996467, establishes confidentiality protocols for exchanging proprietary training data and business records during litigation. This procedural milestone indicates the court is facilitating evidence sharing rather than dismissing claims early, suggesting the suit will proceed toward substantive arguments regarding alleged unauthorized scraping and trademark misuse. Legal analysts view this development as significant because it moves the dispute beyond initial pleadings into fact-intensive discovery where fair use defenses are typically tested. Both parties have agreed to terms governing sensitive document handling, implying anticipated disclosure of technical architecture and licensing negotiations. The case remains one of several high-profile challenges testing whether AI search engines infringe publisher rights through content summarization without compensation or attribution.
