Artificial intelligence startup Legion LegalTech has sued the US government over an order that forced Anthropic to block foreign nationals from accessing its most advanced models.
The company filed the lawsuit Tuesday in federal court in Washington, challenging a June 12 directive issued by the Commerce Department’s Bureau of Industry and Security.
The order required Anthropic to suspend access to Fable 5 and Mythos 5 for any foreign national, including people working inside the United States.
Anthropic disabled the models for all customers worldwide on the same day because it could not guarantee compliance while continuing to offer broader access.
Legion is based in the United States but employs Canadian software developers working from Canada. The company uses Anthropic models to build drafting and case management tools for attorneys.
