Silver - Firms: prosecution and strategy

For over 20 years, ZY Partners has served as the trusted advisor to well-known multinationals, especially on IP litigation matters because it “thinks like a Westerner”. As one foreign associate explains: “The team has excellent English and can advise in plain language. They are technically excellent too, without being ‘formulaic’ in their thinking. They can explain clearly and succinctly the reasoning and logic behind their thinking, while understanding the need to do so in a way that a Western client would understand.” Managing partner Yanling Zheng is “very personable with an excellent client service mentality”. With a 30-year career in intellectual property, seasoned litigator Jingbing Li has extensive experience with IP judicial court procedures, while Xiaohong Li straddles the contentious and non-contentious divide.
