The Patent 1000 focuses exclusively on patent practice and has firmly established itself as the definitive 'go-to' resource for those seeking world-class legal patent expertise.

Gold - Individuals: prosecution

Long admired among peers for its superb technical command, China Science Patent & Trademark Agent is recognised for both its stellar prosecution and contentious offering. Leading the charge is Wei Zhao, who is senior partner, vice president and heads the electronics group. He has particular expertise in one of the hottest technologies on the current patent market, serving as an independent evaluator of the H.265 standard for a well-known patent pool. His colleague Bin Ni is one of the attorneys bringing notice to the firm’s contentious practice and is a wizard when it comes to CNIPA invalidation proceedings.
