The University of Tennessee Research Foundation filed a patent infringement lawsuit against Anthropic in Delaware federal court on July 21, 2026. This legal action represents the first patent infringement case brought against the artificial intelligence leader.
The complaint asserts that Anthropic’s AI systems violate two patents involving machine-learning technology inspired by neuroscience. These patents represent contributions to the fields of AI and machine learning developed by university professors.
The research foundation seeks an unspecified amount in monetary damages and a court injunction to halt further infringement. This lawsuit follows Anthropic’s settlement of a major copyright dispute with authors just one day prior.
