A reputation for quality, diligence and speed has sustained Chang Tsi & Partners for two decades.
We are a strategy-driven, full-service firm. We prioritize teamwork and cooperation, facilitating knowledge and resource sharing across departments. That helps us build each client a ground-up China plan that insulates them from a variety of legal risks.
In China’s enormous and complex market, intellectual property rights mean little without administrative backing. That’s why Chang Tsi & Partners employs a sophisticated in-house investigations team specializing in market monitoring. We leverage our strong relationships and communication channels with law enforcement bodies at all levels, going beyond the courts and the paperwork to safeguard our clients’ rights and protect their interests.
Before taking new clients, we research and identify any potential conflicts of interest. Each client gets a dedicated team of senior attorneys and experts held to the highest standards of accountability. Our sophisticated time-limit notification and processing systems guarantee budget control and billing accuracy.
Chang Tsi & Partners’ strict supervision and risk control systems exceed international benchmarks. On our clients’ behalf, we can manage budgets, plan annual prosecution and enforcement goals, and coordinate with their local businesses.
Our clients stay with us long-term because we know their businesses. We do our research and quickly get up to speed. We make China’s opaque market clear by offering sharp business analysis and market research, regular client reports, and much more.
At Chang Tsi & Partners, we pride ourselves on being efficient and responsive. Our unique pledge to answer all email enquiries in one working day – coordinated by a dedicated workflow team of fifty – sets us ahead.
Chang Tsi & Partners is a genuinely bilingual firm. We work in English and Chinese, and many of our lawyers are accredited to practice internationally: in the US, Europe and the Asia Pacific.
Our practitioners are China’s best, with careers that have tracked the rapid evolution of the Chinese legal system.
Managing partner Simon Tsi is one of China’s most fearsome litigators, and has a long background working with government organizations. With a lifetime of experience in arbitration, corporate law, security and finance law, construction & real estate law, as well as IP, he has overseen some of China’s biggest corporate takeovers. Tsi, who specializes in legal risk prevention and control, has won landmark trademark infringement and unfair competition cases on behalf of Honeywell International Inc., Kraft Inc. and Johnson & Johnson. In 2016, Tsi obtained a rare preliminary injunction on behalf of Under Armor in the high court of Fujian’s IPR tribunal – only the second such injunction the court has issued. Tsi has long-term working relationships with many of China’s most successful businesspeople and specializes in connecting them with overseas firms. He has worked for China’s Department of Justice, the Ministry of Personnel, and the State Power Grid Construction Corporation.
Named the World’s Leading Trademark Lawyer by Who’s Who Legal, founding partner Spring Chang is a razor-sharp IP attorney who has advised and represented hundreds of major electronics, consumer, pharmaceutical, apparel and jewelry companies in the Chinese market, as well as Chinese companies overseas. Chang is well known for representing Best Buy in a precedent-forming trademark case that prompted China’s Supreme Court to re-evaluate the kinds of evidence it is prepared to consider in IP decisions. She has regularly been the only trademark lawyer ranked in the Band 1 tier of Chambers and Partners’ Chinese legal listings—the group has praised her “great judgment” and “wealth of experience in serving well-known multinationals”. Chang has earned an international reputation for creativity and efficiency over more than two decades practicing.
Our attorneys have worked in government agencies, the Chinese judiciary, and as in-house counsel for local and multinational corporations. They are praised for their sharp insights into Chinese government policy, and for their pragmatic commercial awareness.
Chang Tsi & Partners is committed to diversity of background and of thinking. Many of our attorneys have trained both in China and internationally and are qualified to practice in other jurisdictions. Our overseas-born lawyers bring their own rich experience.
At Chang Tsi & Partners our first duty is to our clients’ interests and their legitimate rights. We comply with Chinese and international professional practice standards.
We also take social responsibility seriously. Each year we run a free, weeklong legal aid hotline organized by the Beijing Lawyers Association to service the local Beijing community. We continually contribute to charity groups, including the Interfaith Food Pantry, Doctors Without Borders, the American Heart Association, the Cancer Research Institute and more.
Chang Tsi & Partners supports Xingxing San, a Chinese group that assists children with autism, and the Yiya organization, which provides schooling and support for hearing and speaking-impaired children. We also support education programs for children in Tibet.
As part of our ongoing environmental program Go Green, Chang Tsi & Partners is now a paperless firm. Each year, our staff plants hundreds of trees on the outskirts of Beijing as part of the Chang Tsi Forest Initiative.
And we value our people. Our working environment is regularly commended by the Chinese government and peak trade union. We are the 2017 Asian Legal Business China Employer of Choice. In 2016, the Shanghai Bar Association named our Shanghai branch “Best Organization” in an award that recognizes contributions to public welfare in the Chinese legal profession.
We have provided services for Fortune 500 companies for nearly two decades, and we represent more US Fortune 500 companies than any other Chinese firm. But our clients come from all over the world. We are privileged to have earned the trust of companies from North and South America, Europe, the Asia Pacific, and Africa, in fields as diverse as energy, entertainment & sports, manufacturing, retail, transport & tourism, food & beverages, banking and financial services.
