Chinese artificial intelligence company Shanghai Zhizhen Intelligent Network Technology Co., Ltd., also known as Xiao-i, has filed a lawsuit against Apple Inc, alleging it has infringed on its patents. The company 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. Xiao-i argued that Apple's voice-recognition technology Siri infringes on a patent that it applied for in 2004 and was granted in 2009. Apple did not respond to a request for comment. Reuters was not immediately available to find a copy of the court filing.

Shanghai Zhizhen first sued Apple for patent infringement in 2012 regarding its voice recognition technology.
