Legal tech firm sues US over order limiting foreign access to top-tier Anthropic models
WASHINGTON, June 23 (Reuters) - A U.S. legal technology company on Tuesday sued the federal government, challenging a directive by President Donald Trump's administration that resulted in the artificial intelligence firm Anthropic halting access to two of its most advanced models for users worldwide. Legion LegalTech Corp filed its lawsuit, opens new tab in Washington, D.C., federal court, saying a June 12 order by the U.S. Commerce Department's Bureau of Industry and Security unlawfully required Anthropic to disable its Fable 5 and Mythos 5 models for "any foreign national." Anthropic turned off access for all customers the same day to ensure compliance. San Jose, California-based Legion says it depends on Anthropic's tools for its software platform and that the U.S. government's action immediately cut off access for members of its Canada-based software development team and disrupted its business. The company builds drafting and case-management tools for attorneys. "The harm to Legion is immediate, irreparable, and existential," the lawsuit said. "The pace of frontier AI advancement is blistering, and competitive ground lost during a suspension cannot be regained after the fact." The Commerce Department and White House did not immediately respond to requests for comment. Anthropic is not a party to the litigation. Anthropic on Tuesday referred to a prior statement that said it was "grateful to the administration for their ongoing partnership in working to get this matter resolved as quickly as possible." Legion asked a U.S. judge to vacate and set aside the administration's directive targeting Anthropic. The company also said it would ask for a preliminary order to bar the administration from enforcing the directive. Anthropic and the United States are locked in legal battles in Washington and California federal courts. Anthropic sued the Trump administration after the government moved to place the company on a supply-chain blacklist over its refusal to allow the military to use its AI models for domestic surveillance or fully autonomous weapons.

Someone Is Suing the U.S. For Making Them Go Without Anthropic's Fable 5 Model
Anthropic's Claude Fable 5 AI model was released to the public on June 9 and taken down on June 12. By my math, it was available for a little over three days. Anthropic took down Fable 5 voluntarily in a manner of speaking, but by all accounts it was complying with an export control directive from the U.S. government under threat of penalties. Now a startup called Legion says in a new lawsuit against the government that Claude Fable 5 was so critical to its business that, "Each day the directive remains in force disrupts Legion's product, operations, sidelines its engineers, and erodes the company's ability to survive in a field defined by continuous access to the most capable models," according to Bloomberg, which pulled that line from the court filing. Legion, by the way, is an AI company for lawyers. According to its about page, its product works like this: "Upload your case documents. Legion drafts your pleadings, discovery, and motions in minutes - with built-in editing tools to refine and ship. Export a fully formatted Word document or a bookmarked PDF with exhibits and slip sheets. Ready to file, ready to serve." Arthur Rothrock, the CEO of Legion, said to Bloomberg, "Who's to say they can't do this any other time against another company, like OpenAI?" When Anthropic took down Fable 5, Legion says it "lost the latest tool at the center of its development instantaneously," which caused, "immediate, irreparable and existential" harm, again per Bloomberg. Legion's staff, Bloomberg notes, includes Canadian nationals located in Canada. The Fable 5 model, the most advanced, consumer-facing version of Claude, was part of the same class as the Claude Mythos Preview model which Anthropic had said was too dangerous to release to the public. Fable arrived about two months later, advertised as a version of Mythos with elaborate and conspicuous safeguards. But shortly after its release, the government -- according to media reports from multiple publications -- was informed that Amazon researchers had found workarounds that bypassed the safeguards. This, reportedly combined with previous worries that China-connected entities had access to Mythos, apparently led to the export control order, requiring Anthropic to keep Mythos and Fable away from anyone not a U.S. national. Faced with implementing an almost impossibly intricate citizenship-confirmation scheme in order to use Fable 5, Anthropic announced that it was pulling the plug. Efforts to resolve the issue have been ongoing. Anthopic's statement to Bloomberg when asked about the suit says it is "grateful to the administration," and remains, "committed to working alongside the government towards our shared goals of protecting critical infrastructure and making sure the US leads in AI." The White House and Commerce department apparently didn't respond to Bloomberg.
