The grievance, filed June 14 within the U.S. District Courtroom for the Northern District of California by buyer Karl Kahn, seeks to signify different Claude subscribers who bought the corporate’s Max plans and alleges Anthropic misled prospects concerning the quantity of utilization included with its premium subscription tiers.
Within the lawsuit, Kahn stated he subscribed to Claude Professional in June 2025 earlier than upgrading to Max 5x in January, and Max 20x in April of this 12 months.

In response to Vaca Daffan LLP Founding Companion Kati Daffan, who’s representing Kahn, the case is rooted in established client safety legal guidelines that prohibit corporations from deceptive customers concerning the services they promote.
“This can be a actually good kind of case for a category motion, as a result of the legislation could be very clear that corporations need to be sincere about their promoting and advertising,” Daffan informed Decrypt. “If they don’t seem to be, they are often held liable, want to alter their methods, and refund cash to individuals. Civil actions like this are introduced daily towards corporations that misrepresent one thing about their services or products.”
Anthropic provides a number of subscription tiers for particular person customers, from a free plan with restricted utilization to its paid Professional and Max plans.

The lawsuit seeks damages, restitution, injunctive and declaratory aid, attorneys’ charges, and prices, and asks the courtroom to certify a category motion on behalf of all U.S. residents who bought or upgraded to a Claude Max 5x or Max 20x subscription via Claude.com or the Claude desktop app between April 9, 2025, and the current.

The Claude maker just isn’t alone in advertising premium AI subscriptions primarily based on increased utilization limits.
