China Patent Agent (H.K.) Ltd. Stays in Ranking Tier 1 Among Patent and Trade Mark Prosecution Firms in China 


In the 2009 MIP Global Survey of Law Firms, China Patent Agent (H.K.) Ltd. has again been ranked Tier 1 among the Chinese firms for both the patent prosecution work and trade mark prosecution work.
The MIP Global Survey of Law Firms is an annual event organized by Managing Intellectual Property (MIP) in more than 70 jurisdictions. This survey lasted 5 months and the results are mainly based on the information provided in questionnaires and interviews with hundreds of practitioners and in-house counsels.
The following are the contact details about China Patent Agent (H.K.) Ltd. in this survey, published online at
Headquartered in Hong Kong with three branch offices in Beijing, Shanghai and Shenzhen, China Patent Agent (HK) remains a competitive force in both prosecution and litigation work. Led by general manager Li Yong, the firm serves many foreign multinationals including Philips, GM, GE, DuPont and Ericsson. One client says that the team excels in providing them with information and is "by far the best informed about changes and trends in China's patent law". One of the highlights of CPA (HK)'s work in the past 12 months was its success in defending the validity of its clients' patents against the decisions of the Patent Reexamination Board (PRB). In one case, the PRB declared a patent of leading bicycle components manufacturer Shimano to be invalid. The firm acted for Shimano to file an administrative lawsuit against the PRB at Beijing no 1 Intermediate People's Court and the court recently ruled in favour of Shimano. The firm helped Pfizer and Merck win similar victories.
