Can Hong Kong Trademarks Be Used in Mainland China? Compliance Essentials and Step-by-Step Registration Process

A trademark registered in Hong Kong does not automatically enjoy legal protection in Mainland China if used directly in the Mainland market-posing genuine legal risks. This is a critical point frequently overlooked by cross-border operators.

Why a Hong Kong Trademark Is Not Automatically Effective in Mainland China

Trademark rights are territorial-a fundamental principle of intellectual property law. The Hong Kong Special Administrative Region operates an independent trademark registration system governed by the Trade Marks Ordinance (Cap. 362), whereas Mainland China applies the People’s Republic of China Trademark Law. As two distinct jurisdictions, their trademark registration systems operate independently and do not extend legal effect to each other. Even if the same applicant has obtained trademark registration in Hong Kong, that mark confers no registered trademark rights in Mainland China unless a separate application has been filed and approved there.

Compliance Requirements for Lawful Use in Mainland China

To ensure lawful operation of a Hong Kong brand in Mainland China, one of the following pathways must be completed:

1. File a trademark registration application with the China National Intellectual Property Administration (CNIPA) Trademark Office and obtain a registration certificate;

2. Designate China under the Madrid System for the International Registration of Marks and complete the territorial extension procedure;

3. If involved in import/export of goods, ensure that actual use does not infringe upon others’ prior rights-including already-registered trademarks, unregistered trademarks with a certain degree of influence, and enterprise name rights.

Detailed Overview of the Standard Domestic Registration Route

This route is suitable for most Hong Kong applicants entering the Mainland market for the first time:

1. Determine the proposed trademark design and specify the relevant goods or services (selected according to the Classification Table of Similar Goods and Services);

2. Conduct a similarity search to assess registrability;

3. Entrust a trademark agency registered with CNIPA to file the application (Hong Kong applicants are required to appoint an agent);

4. Submit supporting documents verifying the applicant’s eligibility: Hong Kong companies must provide notarized copies of their Business Registration Certificate and Certificate of Incorporation;

5. Await formal examination, substantive examination, preliminary publication, and final registration approval-the entire process typically takes 12 to 18 months.

Applicability of the Madrid International Registration Route

This route suits brand owners who have held a Hong Kong registration (or pending application) for at least six months and plan multi-jurisdictional expansion:

1. Within six months of obtaining the basic registration or filing in Hong Kong, submit an international registration application to the World Intellectual Property Organization (WIPO) International Bureau;

2. Designate China as a contracting party for territorial extension and pay the corresponding official fees;

3. CNIPA conducts an independent examination of the designation covering China, applying the same substantive standards as for domestic applications;

4. Upon successful examination, the trademark acquires the same legal effect in China as a domestically registered trademark.

Common Risks to Note During Use

Even after registration in Mainland China, proper use remains essential:

1. Do not alter the registered mark without authorization-for example, adding elements, modifying proportions, or changing fonts in ways that materially affect its distinctive character;

2. Non-use of the registered trademark for three consecutive years without legitimate justification may render it vulnerable to cancellation requests by third parties;

3. Use beyond the approved scope of goods or services requires caution: unauthorized cross-class use may constitute infringement or preclude cross-class protection;

4. When using the trademark on platforms such as company names (under Hong Kong law), websites, domain names, or WeChat official accounts, ensure consistency with the registered information.
