Why Us

Chang Tsi & Partners has a team of experienced attorneys specializing in all forms of IP rights prosecution and enforcement, and has represented clients in several high-profile and precedent-setting cases.

Through our enforcement services, we protect and defend our clients' rights across Asia through court litigation, trademark oppositions and cancellations, company name disputes, domain name arbitration, online infringing content takedown procedures, advertising complaints, customs recordals, and anti-counterfeiting litigation.

We also assist in maintaining our clients' trademark rights by continuously scanning new applications for potential infringements and conducting regular checks for violations.

Our litigators are equally experienced in non-litigation aspects such as negotiation and conclusion of settlement agreements, and are always committed to seeking and achieving the most commercially reasonable and cost-effective solutions for our clients.

Our extensive business coverage and deep knowledge and experience give us a unique advantage in providing our clients with enforcement strategies and implementation advice in Asia.
