Our Team
Technology · Law · Language — a three-dimensional service structure
Make the technical solution understood precisely, and protected tightly. That single principle decides how this team is built. Our attorneys all hold science or engineering degrees and have years of practice behind them, covering mechanical engineering, medical devices, electronics, telecommunications, new energy and algorithms. In-house translators working in Chinese, English and Japanese mean a foreign filing never passes through a third party. Every client’s cases are carried by one assigned attorney from start to finish — no handovers halfway.
