ZY Partners has made impressive progress this year, moving up two tiers in the patent contentious table and debuting on the third tier of the trade mark contentious ranking. Commentators speak highly of its litigation skills. A client says: "ZY Partners is a very good litigation firm. I highly recommend it."
The firm often represents foreign brand owners in protecting and enforcing their IP rights. Partner Li Jingbing led a team for Sony Ericsson in a case concerning the trademark Suo Ai, the acronym for Sony Ericsson in Chinese characters, which was registered by a Chinese individual in 2003. Sony Ericsson tried to cancel the mark and its request went through the TRAB, Beijing No 1 Intermediate People's Court and the Beijing High Court, where the company won and lost on different counts, before it was heard at the Supreme's People's Court in 2010. The case has been widely covered in the media.
