A Chinese artificial intelligence (AI) company named Shanghai Zhizhen Intelligent Network Technology (also known as Xiao-i) has filed a lawsuit against Apple over alleged infringement of a voice recognition patent. The company is claiming 10 billion yuan (US$1.43 billion) from Apple, arguing that the technology behind Apple's smart assistant Siri is infringing on a patent that the company was granted in 2009. Xiao-i is also asking Apple to stop manufacturing, using, promising to sell, selling, and importing Siri. In reaction, Apple has indicated that Siri does not contain features included in the mentioned patent. The dispute between the two companies is not new: Xiao-i filed an initial complaint in 2012 and was followed by a request by Apple to invalidate its patent.
