The trademark infringement lawsuit, announced by a Beijing district court, accused iYuba of using the BBC's trademark and content on its apps, websites and social media without any authorisation.
The BBC is seeking 500,000 yuan (USD 78,950) in compensation and asked the company to cease infringing on its trademark registered in China.
The BBC claimed that it had sent letters to ask iYuba to remove its brand name from content and messages, and the Chinese company has yet to respond.
