Apple suffers Siri patent case defeat in China

Apple has failed in its attempt to get a Chinese company's voice-recognition patent ruled invalid.

The verdict threatens Apple's ability to offer its voice-controlled virtual assistant, Siri, in the country. Shanghai-based Zhizhen Network Technology has sought to block Apple from selling products with the app installed, saying it infringed its rights. Apple said it would pursue an appeal with the Beijing Higher People's Court.
