The University of Tennessee Research Foundation has filed a patent infringement lawsuit against Anthropic in Delaware federal court, alleging the AI company's systems violate two patents on neural network technology inspired by neuroscience.

The complaint, filed on July 20 and made public on July 21, argues that Anthropic's AI systems infringe patents covering "significant contributions to the fields of artificial intelligence, machine learning, neuromorphic computing, and neuroscience-inspired computing" invented by university professors. The lawsuit is believed to be the first patent infringement case against Anthropic.

The university's complaint drew a direct line to Anthropic's recent copyright battles, stating: "Anthropic's cavalier approach to others' intellectual property rights in the development of its products extends beyond the use of copyrighted material".

The research foundation is seeking unspecified monetary damages and a court order blocking Anthropic from infringing its patents.

The patent lawsuit comes just one day after a California federal judge approved Anthropic's landmark $1.5 billion settlement in a class action copyright lawsuit brought by authors over the use of their books to train Claude.

The court granted final approval to the settlement, which will award approximately $3,000 per work to authors and publishers whose books were allegedly used without permission. The court also approved roughly $101.6 million in attorney fees, significantly less than the $187.5 million requested by class counsel.

Anthropic has stated it disagrees with the patent infringement allegations and intends to vigorously defend the case. The company recently reached a significant $1.5 billion settlement with authors over copyright claims, which received final court approval.

As the AI intellectual property landscape continues to evolve, the patent lawsuit could have far-reaching implications for how foundational AI technologies are protected and licensed.
