Headquartered in Hong Kong with three branch offices in , and 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 '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 no 1 Intermediate People's Court and the court recently ruled in favour of Shimano. The firm helped Pfizer and Merck win similar victories.
