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.

Client Considerations

Client Considerations After completing legal studies at China University of Political Science and Law, Yuanyi developed a practice that serves foreign individuals, foreign-invested enterprises, and Chinese companies that deal with cross-border issues. Clients typically engage Yuanyi when a project needs careful sequencing: document review, risk mapping, negotiation strategy, and, when needed, administrative or judicial proceedings. Guizhou's economic profile—big data and cloud services in Guiyang, manufacturing and resource industries in other prefectures, and growing cross-provincial logistics—shapes the types of mandates that arrive from overseas headquarters and local joint venture partners. Foreign clients often underestimate how local filing systems, language of record, and evidentiary formalities affect outcomes. For foreign managers, the practical difference between a well-prepared filing package and an incomplete submission is often weeks of delay and avoidable follow-up questions. Representative work themes include:⚖️ Structuring and documenting commercial or regulatory steps before disputes escalate🛡️ Reviewing bilingual materials so Chinese-language versions remain consistent with commercial intent📜 Mapping statutes, administrative rules, and local practice notes that affect a given transaction💼 Coordinating with finance, HR, and operations so legal strategy matches business constraints Yuanyi also assists clients who need to respond to investigations, inspections, or counterparties that have already taken aggressive positions. Yuanyi keeps working knowledge current on amendments that affect foreign investment, employment, product quality, customs, criminal procedure, and intellectual property—areas where foreign parties frequently need local counsel who can translate procedure into actionable steps. Clients receive written issue lists, proposed sequences, and candid notes on evidentiary gaps. Foreign individuals and businesses operating in or dealing with Guizhou benefit from counsel who understands both international commercial expectations and Chinese formalities. For matters involving trademarks in Qiandongnan or elsewhere in Guizhou, Yuanyi provides English-capable communication for overseas stakeholders while ensuring Chinese filings and court or agency submissions meet local formal requirements.

Foreign companies should register trademarks and patents in China early, monitor for potential infringement, and establish evidence chains for enforcement through administrative complaints or court actions.
