Anthropic, a prominent AI research firm, introduced its Mythos AI model in June 2026. Prior to this release, the U.S. Patent and Trademark Office (USPTO) had denied Anthropic’s applications to register the “Claude Mythos” trademark, citing potential confusion with Global Printing’s existing registration.

In the lawsuit, Global Printing contends that Anthropic’s adoption of the “Mythos” name for its AI model is likely to mislead consumers and dilute the distinctiveness of its brand. The company is seeking unspecified damages and a court order to prevent Anthropic from using the “Mythos” name.
