Silver - Firms: prosecution

With “extensive experience in handling patent prosecutions in Korea”, NAM & NAM has developed its expertise since the earliest stages of Korean intellectual property. Clients can rest assured that their intangible assets are handled with the utmost professionalism and sensitivity, given the firm’s ISO27001 and ISO9001 certifications. For many large multinational corporations, the team of nearly 50 patent attorneys – many of whom are headquartered in Europe and the United States – is the obvious choice. After 15 years of working for Qualcomm in California and Samsung in South Korea, managing partner Ben (Beyong-ho) Yuu has returned to NAM & NAM to focus on growing its domestic client base. An invaluable member of the IP strategy group, Sung-wook Kim specialises in electronics, semiconductor and computer software.
