Bronze - Firms: prosecution and strategy

A favourite among tech giants, multinationals and fast-growing enterprises, the dynamic IP boutique excels at tailoring its advice to each service user. The set is well known for its litigious capability and has unparalleled experience in handling complex IP litigation and technology-related matters in China. Credit in this regard is due to Xiaohong Li and Jingbing Li, who both have both showcased a remarkable record of success before the Supreme People’s Court over the course of their respective careers. Described by one patron as a “creative thinker”, Xiaohong is well-versed in Chinese trademark law and often tasked with high-stakes trademark and copyright litigations by multinationals. IP disputes are also the forte of founder Jingbing, who has represented domestic and international entities in IP contentious matters since 1990. A polished and esteemed litigator and familiar with different levels of IP court procedure, he has been in charge of a slew of litigations that have been used and cited as exemplary cases by IP judges and journals. Making her debut in the WTR 1000 this year, ex-Beijing IP judge Mengling Liu has a wealth of trial experience. During her time on the bench, she heard more than 200 IP cases, some of which were deemed to be highly influential. Over the prosecution department, brand protection maven Yanling Zheng has frequently been instructed by well-known brands to look after their vast Chinese portfolios. “Yanling makes the complexities of navigating Chinese trademark and copyright law much more manageable.”
