A Chinese State-owned film studio is suing Apple, alleging that the company sold its animated movies on iTunes without permission, reported the South China Morning Post.

The 3.3m CNY ($531,000) lawsuit follows five consecutive days of media attacks by the State-owned People’s Daily, claiming Apple’s customer service and refund policies in China are inferior to those offered in other countries. Apple is also being sued by a Shanghai-based company that alleges Siri infringed a patent used in its own ‘Xiao i Robot’ voice-recognition systems …

The latest case is set to be heard in a Beijing court.

A senior official with the Shanghai company confirmed that it had filed the litigation with the Beijing No 2 Intermediate People’s Court, which accepted the case.
