About us

The Wanhuida Intellectual Property began with Beijing Wan Hui Da Intellectual Property Agency (Wan Hui Da), which was established in 1999, with its head office in Beijing. For growing professionals and for meeting clients’ growing service needs, some core members of the Wan Hui Da team who were licensed to practice law left Wan Hui Da and created Beijing Wan Hui Da Law Firm. Because of their history and their providing different aspects of services for their shared clients, Beijing Wan Hui Da Intellectual Property Agency and Beijing Wan Hui Da Law Firm, in spite of their independent legal status, share the brand name and commercial reputation of Wan Hui Da. Their cooperative development under joint leadership of core teams of both organizations resulted in a united Wanhuida intellectual property service that is more comprehensive, professional, and potent. Wanhuida is now home for some 450 employees working exclusively in the field of intellectual property.
