See sources at the end.

The U.S. Department of Justice has submitted an amicus brief in the consolidated New York Times v. OpenAI litigation, arguing that training large language models may constitute fair use due to the transformative nature of generative AI and its implications for national security and economic competitiveness. Although the government explicitly stated that its filing does not bind the court or determine the case's outcome, this intervention signals a significant federal stance that could reshape how legal teams evaluate copyright risks associated with AI training data.

Why Now: The DOJ Enters the AI Copyright Arena

On September 1, 2026, the U.S. Department of Justice submitted an amicus curiae brief to the Southern District of New York, marking a significant federal intervention in the consolidated New York Times v. OpenAI litigation. This filing represents a notable shift in the legal landscape, as the federal government has formally entered the debate over the permissibility of using copyrighted material to train large language models. By taking this step, the DOJ has signaled that the question of fair use in the context of artificial intelligence is not merely a private commercial dispute but a matter of broader public interest.

In its submission, the Department of Justice supported the argument that the training of large language models may constitute fair use under copyright law. The government’s position highlights the transformative nature of generative AI training, asserting that the process of converting raw text into model weights is sufficiently distinct from the original works. Furthermore, the brief emphasized that this issue is closely tied to national security and economic competitiveness, suggesting that the development of advanced AI capabilities is a strategic priority for the United States. This stance contrasts with the position of the New York Times, which filed its original lawsuit in 2023 against OpenAI and Microsoft, alleging that millions of its articles were used without authorization for model training. While the DOJ’s brief does not determine the outcome of the case or bind the court, its entry into the proceedings adds a layer of governmental perspective to the ongoing legal battle.

Core Issue: Government Stance on Transformative Use

The U.S. Department of Justice has formally entered the ongoing copyright dispute by submitting an amicus curiae brief to the U.S. District Court for the Southern District of New York on September 1, 2026. In this filing, the government explicitly supports the argument that training large language models may qualify for fair use protection under copyright law. The DOJ’s position centers on the concept of "transformative use," asserting that the process of training generative AI models is highly transformative in nature. By characterizing the extraction and utilization of data for model training as a fundamentally new purpose distinct from the original creative works, the government aligns with the legal framework that prioritizes the creation of new knowledge and tools over the protection of original expression in this specific context.

Beyond the legal technicalities, the DOJ’s brief underscores the broader strategic importance of artificial intelligence to the United States. The government argues that the development and deployment of generative AI are critical to maintaining national security and ensuring economic competitiveness on the global stage. This perspective suggests that overly restrictive interpretations of copyright law could hinder innovation and place the U.S. at a disadvantage against other nations advancing their AI capabilities. By linking the legal doctrine of fair use to these high-level national interests, the DOJ provides a policy-driven rationale for why the courts should view AI training data usage through a lens of public benefit rather than solely as a potential infringement.

It is important to note that the New York Times, which filed the original lawsuit against OpenAI and Microsoft in 2023, has criticized this government stance. The newspaper maintains that millions of its articles were used without authorization for model training and emphasizes that the legal dispute remains active. While the DOJ’s brief highlights the transformative nature of AI training and its alignment with national interests, it does not settle the specific claims regarding unauthorized access or the scale of data usage alleged by the plaintiffs.

The DOJ’s position frames AI development as a matter of strategic national interest, influencing how the court may weigh the public benefit of such technology.

Context: The New York Times' Copyright Claims

The legal dispute over AI training data traces back to 2023, when The New York Times filed a lawsuit against OpenAI and Microsoft in the U.S. District Court for the Southern District of New York. The core of the complaint alleges that millions of the newspaper's articles were ingested into large language models without authorization or compensation. By framing the unauthorized use of its copyrighted content as a direct infringement, The New York Times challenged the legality of such data ingestion practices, arguing that the sheer volume of text used for model training exceeded the scope of permissible fair use. This litigation has since become a central battleground for determining how copyright law applies to the massive datasets required for modern generative AI development.

As the case progressed, it was consolidated with other related claims, leading to the current unified litigation where the Department of Justice recently submitted its statement of interest. The New York Times has actively contested the government's recent support for fair use, criticizing the DOJ's stance and emphasizing that the legal questions regarding data ingestion remain unresolved. The newspaper maintains that its claims are valid and that the government's involvement does not negate the ongoing nature of the dispute. This tension highlights the high stakes involved, as the outcome could set a precedent for how news organizations and other publishers protect their intellectual property against automated scraping and model training.

Origin of the Suit: The New York Times initiated the copyright infringement case against OpenAI and Microsoft in 2023.
Primary Allegation: The complaint asserts that millions of articles were used for model training without permission.
Legal Challenge: The lawsuit questions whether the scale and purpose of this data ingestion constitute a legal violation of copyright.
Current Status: The dispute remains active, with The New York Times continuing to oppose the government's recent fair use arguments.

Legal Limitations: Non-Binding Nature of the Statement

The Non-Binding Nature of the DOJ Statement

It is crucial to understand that the U.S. Department of Justice’s submission does not serve as a final ruling on the merits of the case. In its statement filed on September 1, 2026, in the Southern District of New York, the DOJ explicitly clarified that its position does not determine the outcome of the litigation or bind the court to any specific legal interpretation. This distinction is vital because, while the government’s perspective on the transformative nature of large language model training carries significant weight, the ultimate authority to interpret copyright law and apply it to these specific facts remains with the presiding judge. The statement functions as an expression of the executive branch’s policy view rather than a judicial precedent.

Consequently, the legal dispute between The New York Times and the defendants remains fully active and unresolved. The Times has publicly criticized the government’s stance, emphasizing that the copyright infringement claims are still pending and that the DOJ’s input does not negate their right to seek a ruling in their favor. For legal practitioners and stakeholders, this means that the DOJ’s support for fair use is a strong signal of executive alignment but does not guarantee a favorable verdict. The court will still need to conduct its own independent analysis of whether the use of millions of articles for model training meets the legal thresholds for fair use, regardless of the government’s advocacy.

No Precedential Value: The DOJ statement is an amicus-type filing that does not create binding legal precedent for other courts.
Judicial Discretion: The judge in the Southern District of New York retains full discretion to rule contrary to the government’s position if the facts and law warrant it.
Ongoing Litigation: The New York Times has reiterated that the case is still in progress, and the DOJ’s filing does not halt or conclude the proceedings.
Policy vs. Law: The statement reflects a policy preference regarding national security and economic competitiveness, which is distinct from the specific legal determinations required in this copyright suit.

Practical Impact: Shifting Risk for AI Developers

Although the Department of Justice’s statement is not a binding legal precedent, its endorsement of fair use in the context of large language model training significantly alters the risk landscape for AI developers. By explicitly supporting the argument that generative AI training is highly transformative and tied to national security and economic competitiveness, the government has signaled a regulatory environment that is more favorable to the use of copyrighted data for model development. For companies currently building or scaling AI systems, this federal alignment may reduce the perceived legal uncertainty surrounding the ingestion of public-facing content, potentially encouraging greater investment in training datasets that include news articles and other protected works.

This shift does not guarantee immunity from copyright claims, as the New York Times has continued to litigate its case against OpenAI and Microsoft, asserting that millions of articles were used without authorization. However, the DOJ’s intervention adds a layer of governmental support that plaintiffs may find difficult to counter in future proceedings. Developers should interpret this as a reduction in, rather than an elimination of, legal exposure. The practical implication is that while the threat of litigation remains, the strategic weight of the government’s position may influence settlement dynamics and the likelihood of successful defense in similar cases.

Reduced Regulatory Uncertainty: The government’s stance suggests a more permissive approach to AI training data, lowering the perceived legal risk for developers.
Strategic Litigation Advantage: The DOJ’s support for transformative use provides a strong argumentative foundation for defendants in ongoing and future copyright disputes.
Continued Litigation Risk: The New York Times’ active litigation and criticism of the government’s position indicate that copyright holders will continue to challenge unauthorized use.
Economic and Security Context: The emphasis on national security and economic competitiveness may further insulate AI development practices from strict copyright enforcement in the near term.

What to Check: Monitoring Ongoing Litigation and Policy

Monitoring the Active Dispute

Legal teams must recognize that the Department of Justice's recent intervention does not conclude the legal battle between The New York Times and OpenAI. The government filed an amicus curiae brief with the U.S. District Court for the Southern District of New York on September 1, 2026, supporting the argument that training large language models may constitute fair use. While the DOJ emphasized the transformative nature of generative AI and its relevance to national security and economic competitiveness, the brief explicitly stated that it does not bind the court or determine the final outcome of the case. Consequently, the litigation remains active, and the legal landscape is still subject to judicial interpretation and further procedural developments.

The New York Times has actively contested the government's position, criticizing the stance and reiterating that the dispute is far from over. The publisher’s core claim, originally filed in 2023, alleges that millions of articles were used without authorization to train the models. Because the DOJ’s statement is non-binding, it serves as a significant policy signal rather than a definitive legal precedent. Legal professionals should therefore avoid assuming a guaranteed victory for AI developers based solely on this federal support. Instead, the focus should remain on the specific arguments presented by both parties and the evolving judicial reasoning within this consolidated lawsuit.

Track the NYT's Rebuttal: Monitor how The New York Times responds to the DOJ's brief, as the publisher has already publicly criticized the government's position and emphasized the ongoing nature of the legal conflict.
Watch for Court Rulings: The final decision rests with the U.S. District Court for the Southern District of New York; legal teams should prepare for potential rulings that may differ from the government's preferred interpretation of fair use.
Assess Risk Dynamically: Given that the DOJ's stance does not guarantee a final fair use victory, companies should continue to evaluate their copyright risk exposure and consider defensive strategies that do not rely exclusively on this specific government statement.
