Most Asian countries adopt the Nice Classification system, with China, Japan and South Korea using the 11th edition. Some jurisdictions like India and Indonesia have additional sub-classifications. ASEAN members are working towards harmonizing their classification systems.
Beyond conventional marks, China accepts sound marks, Japan allows position marks, while Singapore recognizes hologram marks. Non-traditional marks like color/scent marks face more challenges in developing Asian markets.
We have represented clients across the Greater China region and internationally in technically complex and high-impact cases. Through patent litigation, invalidation proceedings, administrative enforcement, customs protection, and cross-border actions, we safeguard our clients' innovations throughout Greater China and Asia.
We also assist clients with patent monitoring, competitor patent analysis, and freedom-to-operate (FTO) assessments to proactively manage risks. Our patent litigators are equally skilled in negotiation, settlement, and licensing transactions, always aiming to maximize client value.
With broad industry coverage and cross-border capabilities, Chang Tsi is uniquely positioned to develop and implement effective patent protection and enforcement strategies across Asia.
