ZY Partners is a leading China-based law firm specializing exclusively in intellectual property (IP), dedicated to delivering comprehensive, strategic legal solutions to multinational corporations, innovative enterprises, and high-tech companies worldwide. With a core focus on IP litigation, trademark enforcement, design patent protection, and anti-unfair competition, we have established a reputation for securing landmark judgments and setting industry precedents that shape IP practice in China.
Our strength lies in our unparalleled litigation prowess: we have successfully obtained favorable rulings from the Supreme People’s Court, Beijing High People’s Court, and Beijing Intellectual Property Court on critical IP issues, including well-known mark recognition, merchandising right protection, naming right safeguards, and the crackdown on malicious trademark squatting. Notable successes include securing the first judicial recognition of a product’s trade dress under the PRC Anti-Unfair Competition Law, winning precedent-setting design patent infringement cases for leading tech enterprises, and invalidating numerous maliciously squatted marks through administrative and judicial proceedings. Many of our cases have been designated as guiding precedents by national and local courts, serving as benchmarks for similar disputes.
We offer end-to-end IP services, seamlessly integrating trademark prosecution, patent registration, copyright protection, and cross-domain dispute resolution. Our trademark team is uniquely staffed by litigation-focused lawyers, who bring litigation insights to prosecution work—an advantage that fosters long-term client partnerships, with over 80% of our clients collaborating with us for more than a decade. This synergy of prosecution and litigation expertise ensures that clients receive proactive, future-proof IP protection strategies tailored to their business needs.
Our industry expertise spans consumer goods and services, technology and telecommunications, industrials and manufacturing, pharmaceuticals and life sciences, and media and entertainment. We are consistently recognized by top global legal rankings, including Chambers and Partners, World Trademark Review (Silver and Gold categories for enforcement, prosecution, and individual lawyers), LEGALBAND (Band 1-2 for IP Litigation), Managing Intellectual Property (Tier 2-3 for trademark contentious and litigation), and China Trademark Association (5A-rated Trademark Agency).
Beyond legal excellence, we embed diversity, equity, and inclusion (DEI) into our core operations, fostering female leadership, providing equal growth opportunities for all team members, and supporting pro bono legal work for underprivileged individuals and small businesses. ZY Partners is committed to safeguarding clients’ innovations, driving market integrity, and setting the standard for rigorous, client-centric IP protection in China.
