Apple is reportedly suing a Chinese government agency and a Chinese company over patent rights for Siri, according to the Xinhua news agency. The Cupertino company has targeted Shanghai’s Zhizhen Network Technology, which “developed software similar to Siri,” and the State Intellectual Property Office, which controls Chinese patent rights protection. Apple was previously denied a request by the agency to declare the Zhizhen patent invalid, the report claims. The case will be heard on Thursday; Apple declined comment. [via AFP]
