A Chinese court has ruled against Apple in a patent-infringement case over speech recognition technology, according to Reuters.

The Beijing First Intermediate Court ruled against Apple on Tuesday by upholding a patent held by Shanghai-based Zhizhen Internet Technology company.

"Unfortunately, we were not aware of Zhizhen's patent before we introduced Siri (speech recognition technology) and we do not believe we are using this patent," a Beijing-based Apple spokeswoman wrote in an emailed statement to Reuters.

The recent ruling allows Zhizhen to continue a case against Apple for infringing intellectual property rights, Reuters reports. Zhizhen sued Apple in 2012 for intellectual property rights infringement, claiming that the company’s Siri violated Zhizhen's voice system patents.

Apple reportedly intends to take the case to the Beijing Higher People's Court.
