After settling a US$60 million lawsuit with Chinese company Proview, Apple now faces yet another costly lawsuit in China. This time the complaint focuses on Siri and is initiated by Zhizhen Network Technology, a Chinese company with its own voice assistant software. According to a report in M.I.C. gadget, Zhizhen claims that "Apple's Siri infringes on one of Zhizhen's patents so-called 'ZL200410053749.9', which is a patent for 'a type of instant messaging chat bot system' called Xiaoi Bot." The lawsuit currently is in pre-trial negotiations. You can read more about Zhizhen and the Xiaoi voice assistant on M.I.C. Gadget's website.
