Yuanyi Sun

Yuanyi Sun is a licensed attorney practicing in Qiandongnan, Guizhou, with approximately 16 years of experience focused on trademarks. Yuanyi Sun aims to bridge that gap with precise language, disciplined document control, and practical litigation and administrative awareness. Yuanyi Sun applies those lessons to each new matter with attention to the client's industry, counterparties, and risk tolerance, always within the limits of professional ethics and applicable law.

Practice Focus

Practice Focus Work is grounded in the Civil Code, specialized statutes, and provincial practice in southwest China rather than generic national talking points alone. At Guizhou Zhengheng Law Firm, Yuanyi Sun handles matters that require both statutory analysis and operational awareness. Clarifying those mechanics early reduces costly rework after a dispute has already started. Practice in Trademarks demands familiarity with both national rules and how local authorities and courts apply them. Informal understandings that never appear in the Chinese contract text rarely help later. Subsequent practice refined that foundation through repeated exposure to Guizhou-based projects and multi-province matters involving coastal counterparties. Where a matter requires specialists in another city or a different technical field, Yuanyi identifies that need early rather than stretching a mandate beyond effective capacity. The goal is to protect lawful interests within the framework Chinese law actually provides. Yuanyi regularly explains which authority has primary jurisdiction, which materials must be notarized or legalized for use in China, and which steps can proceed in parallel. Training at China University of Political Science and Law provided a foundation in civil, commercial, and procedural law. That dual-track communication reduces misunderstandings between headquarters and on-the-ground teams. Yuanyi treats each engagement as a closed loop from intake through written closing notes that capture residual risks for management.

Intellectual property protection in China includes trademark registration, patent filing, copyright enforcement, and trade secret protection. Yuanyi Sun helps clients develop IP strategies, handle infringement matters, and navigate the administrative and judicial enforcement systems.
