Headquartered in Guangzhou, the “very high calibre” Advance China IP Law Office has grown in the space of two decades into one of the nation’s biggest full-service IP firms, home to almost 900 IP professionals. The patent team consists of 417 patent attorneys and engineers – more than enough to advise across all of the major tech verticals. Client service is a point of pride for the outfit – “ACIP treat each of our cases as though it is their most important matter” – and communication is a strength. One highly ranked US patent firm praises the team’s English language skills, while a major Japanese manufacturer expresses appreciation that members can communicate with their attorney in fluent Japanese. Shanghai-based Chong He manages ACIP’s international patent department: “His team represents several of our most important clients in China, ensuring that we obtain the best possible patent scope through their excellent interactions with CNIPA.” He has few peers, one of just three practitioners ranked as “highly recommended” in a crowded prosecution market. Wenwen Wang wins plaudits for work on life sciences patent prosecution: “She understands the technology involved and provides good guidance on responding to office actions. Her professionalism is excellent.” ACIP’s litigation capabilities also deserve a mention. The firms sees its broad geographic footprint as an advantage. From its home base in Guangzhou, its lawyers can supervise evidence collection across China’s high-tech manufacturing heartland, a key challenge given absence of discovery procedures in the country. Up in Beijing, a specialised patent invalidation group offers both offensive and defensive solutions for parties embroiled in conflict. Minhui Zeng is one of the firm’s go-to contentious experts. Based in Guangzhou, his resume includes earning one of China’s biggest patent damages awards for client Gree a few years ago. ACIP recently inaugurated a new office in Wuhan, a major university town and home of several important private sector R&D campuses. International clients should know that the outfit is the first choice of many top Chinese firms. One of the country’s biggest tech firms comments: “They have been a great help to us in terms of patent prosecution and portfolio management. We periodically rank our patent agencies and ACIP attorneys always score highly.”

ACIP specialises in the following, in particular:

  • patent prosecution, such as patent drafting and prosecution in China; patent registration in Hong Kong and Macau; patent re-examination and appeal; patent invalidation; patent search and analysis; and patent transactions and licensing; and
