In a social media post, the company called on Apple to immediately cease “manufacturing, using, promising to sell, selling, and importing” products that infringe on its patents.
The company is seeking 10 billion yuan (equivalent to $1.43 billion) in damages. If successful, the suit could block Apple from selling some of its most popular products to the Chinese market, its most significant source of income outside of the US.
At the heart of the dispute is the voice-recognition technology that Apple uses in its Siri virtual assistant, which Xiao-I claims to be in violation of a patent it applied for in 2004 and received in 2009.
This latest filing marks a new step in a legal dispute that has continued for almost a decade. Xiao-I initially sued Apple for patent infringement in 2012, and China’s Supreme People’s Court ruled in July that its patent was valid.
Apple did not respond to a request for comment. Reuters was not immediately able to find a copy of the court filing.
