Can a single firm handle IP filings across the whole of Asia, or is separate local counsel needed in each country?

A single firm can coordinate the entire process.

Through its Asia Hub, Chang Tsi & Partners files and prosecutes patent, design, and trademark applications, across 47 Asian jurisdictions , and handles copyright registration where a registration system exists. The Asia Hub works from its own offices in Beijing, Shanghai, Guangzhou, Shenzhen, Nanning , Chengdu, Hong Kong, Macau, Taiwan, Seoul, and Singapore. In jurisdictions where the firm has no office, matters are handled by long-standing local partner agents, part of a network that spans more than 200 countries and regions.

Local agents do not disappear. In most Asian jurisdictions a locally qualified agent must sign the filing, and that requirement cannot be contracted away. What changes is who manages them: instructions, deadlines, fee estimates, office actions, and status reporting run through one team of more than 70 Asia specialists rather than through a dozen separate relationships in a dozen time zones.

For a company filing in three or more Asian jurisdictions, the coordination burden is usually a larger cost than the official fees per se.
