Xiao-i is calling for 10 billion yuan ($1.43 billion) in damages and demands that Apple cease “manufacturing, using, promising to sell, selling, and importing” products that infringe on the patent, it said in a social media post.
Apple did not respond to a request for comment. Reuters was not immediately available to find a copy of the court filing.
The lawsuit marks the continuation of a dispute that has been ongoing for nearly a decade.
Shanghai Zhizhen first sued Apple for patent infringement in 2012 regarding its voice recognition technology. In July, China’s Supreme People’s court ruled that the patent was valid.
