TongHui supports overseas companies, inventors and partner firms with practical intellectual property services in China. We connect local filing and enforcement work with communication that international teams can understand, review and act on.
Protecting intellectual property in China often involves more than a single filing. The right approach depends on the asset, the commercial timetable, earlier applications, disclosure history and how the right may eventually be used.
TongHui organizes that complexity into a clear working process. We help clients and overseas counsel understand what information is needed, what decision comes next and how China-specific requirements affect the broader portfolio.
Our work covers patent applications and national phase entry, invention patents, utility models, design patents, trademark registration, office action responses and intellectual property enforcement. This connected service model helps clients carry context from filing through prosecution and, when needed, dispute support.
Our team supports patent filing, prosecution, design protection, trademark work and related intellectual property matters. Different technical and regional perspectives are coordinated through one service approach, helping overseas clients and partner firms receive consistent documents, deadlines and reporting. The professionals below represent part of the wider TongHui network.
