News Corp opposes Perplexity motion in Dow Jones copyright suit

Litigation between legacy media publishers and AI developers has established a recurring procedural pattern centered on the tension between copyright exclusivity and technological innovation. Historically, plaintiffs in these disputes have increasingly paired traditional copyright infringement claims with ancillary causes of action such as false designation of origin, unfair competition, or breach of contract. This multi-pronged pleading strategy is designed to create redundancy; if a court finds that AI training or summarization qualifies as fair use under copyright law, the non-copyright claims may still survive based on consumer protection or misappropriation theories. Conversely, defendants routinely employ early-stage procedural motions to sever these ancillary claims, arguing they are preempted by federal copyright statutes or fail to state a plausible claim independent of the copying itself. This dynamic transforms initial motion practice into a proxy battle over the ultimate scope of liability, where the survival of non-copyright claims often signals judicial skepticism toward broad fair use defenses. The use of sealed filings in such cases is also a recognized precedent, typically employed when motions require discussion of proprietary scraping methodologies, unreleased product features, or confidential licensing terms that could prejudice either party if disclosed publicly during active litigation.

On October 28, 2026, News Corp and its subsidiary Dow Jones & Company formally opposed a pending motion filed by Perplexity AI in the ongoing copyright and false designation of origin litigation, case number CL69280523. The opposition was executed through a sequence of three distinct court filings submitted within minutes of each other, signaling a coordinated procedural response to Perplexity’s attempt to narrow or dismiss aspects of the lawsuit. According to docket records tracked by legal monitoring services, Document #222 served as the primary 'Response in Opposition to Motion,' articulating News Corp’s substantive legal arguments against Perplexity’s position [2]. This was immediately followed by Document #223, a secondary 'Response in Opposition to Motion' that submitted additional arguments, suggesting a bifurcated strategy addressing separate legal theories or evidentiary matters raised by the defense [3]. A Certificate of Service (Document #224) was filed concurrently to confirm that all opposition briefs had been properly served to all parties involved in the litigation [4].

The timing of these oppositions is significant. They were filed less than two hours after a sealed document (Document #221) was entered into the record on October 27, 2026 [1]. While the contents of Document #221 remain under seal and are not publicly disclosed, its proximity to the public opposition filings suggests it may contain sensitive commercial information, proprietary technical details regarding Perplexity’s AI architecture, or confidential settlement-related communications that necessitated judicial protection. The sealing of this document indicates that the dispute involves granular factual disputes beyond high-level legal theory, potentially touching on specific instances of alleged infringement or internal business practices that either party deems too sensitive for the public docket.

News Corp’s opposition centers on two primary legal theories: copyright infringement and false designation of origin. The plaintiff alleges that Perplexity’s AI search engine creates unlicensed summaries of Wall Street Journal content, thereby infringing on Dow Jones’ copyrights. Furthermore, the 'false designation of origin' claim asserts that Perplexity misrepresents the source or nature of this content to users, potentially creating confusion about whether the summarized information is an authorized product of the news organization. By filing two separate opposition documents (#222 and #223), News Corp appears to be treating these claims as legally distinct hurdles for Perplexity to overcome, rather than collapsing them into a single fair use defense. This procedural posture forces Perplexity to defend not only its right to use copyrighted material but also the accuracy and attribution mechanisms of its AI summarization technology.

Perplexity AI, as the defending party, has utilized procedural motions to contest the scope of News Corp’s allegations. While the specific text of Perplexity’s motion is not detailed in the available docket entries, standard defense strategies in AI copyright litigation typically involve motions to dismiss based on fair use doctrines, arguments that web scraping constitutes permissible access, or challenges to the standing of specific claims. News Corp’s dual-document opposition implies that Perplexity’s motion likely sought to decouple the false designation claim from the copyright claim or argued that the latter preempts the former. News Corp’s decision to file supplementary arguments in Document #223 specifically suggests that Perplexity’s motion introduced novel procedural objections that required a tailored rebuttal beyond the standard copyright opposition.

This latest exchange represents a critical juncture in the discovery and motion practice phase of the case. The transition from initial pleadings to active motion practice tests the legal viability of the claims before the case proceeds to full discovery or trial. For News Corp, successfully opposing Perplexity’s motion preserves the breadth of their legal theory, keeping both copyright and trademark-adjacent claims alive. For Perplexity, the motion represents an attempt to streamline the litigation and establish early precedents favorable to AI search models. The court’s eventual ruling on this specific motion will likely serve as an early indicator of how the judiciary views the intersection of generative AI summarization and traditional intellectual property protections, setting the tone for subsequent proceedings in case CL69280523.

News Corp and similarly situated publishers risk losing a critical alternative legal theory if Perplexity's motion succeeds, potentially limiting future enforcement to pure copyright claims vulnerable to fair use defenses. Perplexity faces continued litigation burden and potential liability for misattribution even if copying is deemed fair, affecting operational costs and product design. The magnitude extends to the broader AI search sector, as survival of false designation claims would incentivize similar multi-theory complaints across the industry. While no monetary damages are specified in current filings, the precedent set here determines whether AI companies must negotiate licenses for attribution accuracy separately from content usage rights, fundamentally altering the economics of AI-powered search and summarization services.
