A Beijing court has ruled in favour of Facebook and against a Chinese company which had registered “face book” as a separate trademark.
The court said the firm had “violated moral principles” with “obvious intention to duplicate and copy from another high-profile trademark”.
The Zhongshan Pearl River company had registered the name in 2014.
Facebook is blocked in China but has recently gone on a charm offensive to access the Chinese market.
The court statement – released on April 28 but not widely covered in English – has led Chinese local media to speculate whether Beijing’s hard stance against Facebook might soften.
During a recent visit to China, Facebook founder Mark Zuckerberg met with China’s propaganda chief Liu Yunshan as well as fellow media guru Jack Ma.
In what critics described as a publicity stunt to win China’s favour, he also went for a run on Beijing’s Tiananmen Square despite heavy pollution.
