Justice Department files legal brief supporting fair-use doctrine for LLM training, reshaping AI industry litigation landscape.
The Trump administration has thrown its weight behind OpenAI and Microsoft in their ongoing copyright dispute with The New York Times, filing a formal legal brief that characterizes the training of large language models on copyrighted material as permissible fair use.
According to AI Weekly, the Justice Department submitted its statement of interest to a Manhattan federal judge on Tuesday, inserting the federal government into one of the most consequential legal battles shaping the future of artificial intelligence development. The filing arrives just days before key summary judgment motions are due before Judge Sidney H. Stein in the Southern District of New York on Friday, September 5.
The government's intervention represents a significant turn in a lawsuit that has drawn intense scrutiny from the tech sector, policymakers, and copyright advocates alike. The Times initiated the legal action against OpenAI and Microsoft in late 2023, arguing that the companies unlawfully used its published journalism and archives to train their generative AI systems without compensation or permission.
What the Brief Argues
The Justice Department's position frames machine learning training as a transformative use of source material, a cornerstone of fair-use legal doctrine. The administration contends that processing copyrighted text to build AI models that generate original outputs constitutes a sufficiently different purpose from the original creation, potentially insulating tech companies from copyright liability.
This framing carries enormous implications. If courts ultimately accept the government's reasoning, it would substantially reduce legal obstacles to how AI companies acquire and process training data. Conversely, a ruling against fair use could impose new compliance burdens and licensing requirements on the AI industry.
Why the Timing Matters

The filing's placement immediately before summary judgment motions signals the administration's view that the case merits expedited judicial consideration. Summary judgment requests seek to resolve disputes without a full trial, potentially allowing OpenAI and Microsoft to escape costly discovery processes and potential jury trials.
The government's intervention also reflects a broader policy posture favoring technological innovation over traditional intellectual property enforcement. This stance mirrors longstanding tensions between copyright holders and technology companies over the permissible scope of data use.
Industry and Legal Implications
A favorable ruling could embolden AI companies to continue expansive training practices with minimal legal risk
Copyright holders and publishers may face uphill battles seeking compensation for content used in AI development
The decision could establish precedent influencing similar litigation involving other AI firms and creative industries
Policymakers may accelerate legislative proposals to clarify AI training rights and creator protections
The case highlights unresolved tensions within the AI ecosystem. While companies argue that broad data access accelerates beneficial AI development, content creators contend that using their work without compensation or consent constitutes theft, regardless of AI's transformative capabilities.
The outcome will likely reverberate far beyond this single lawsuit. Media organizations, authors' groups, and entertainment companies are watching closely, as their business models depend on controlling how their intellectual property is used. Meanwhile, AI developers view training data access as fundamental to building competitive systems.
Judge Stein's decisions on the September 5 motions could clarify whether fair-use protections shield AI companies from copyright liability or whether new legal frameworks are necessary to balance innovation with creator rights.
