Alleges government failed to invalidate Zhizhen voice recognition patent
Apple has filed a lawsuit against China's State Intellectual Property Office, as well as Shanghai company Zhizhen Network Technology, according to news agencies Xinhua and Agence France-Presse. Zhizhen owns a voice recognition patent which Apple previously asked the SIPO to invalidate. The lawsuit is due to reach the Intermediate People's Court on Thursday.
In 2013 Zhizhen sued Apple, charging that the Siri voice command system on iOS devices copies its Xiao i Robot software. The latter was patented in 2004, some seven years before Siri was integrated into iOS. A hearing on Zhizhen's case was held in July, but no ruling was issued at the time.
