Trade marks in Hong Kong vs mainland China: what businesses need to know

Hong Kong vs China Trade Mark Differences for Businesses

Businesses expanding into the Chinese market often assume a Hong Kong trade mark registration extends to mainland China. It does not. The question of Hong Kong vs China trade mark protection is straightforward: Hong Kong and mainland China are separate jurisdictions, each with its own trade mark register. A registration with the Hong Kong Intellectual Property Department gives rights only in Hong Kong. To protect a mark in mainland China, file a separate application with the China National Intellectual Property Administration (CNIPA).

Territorial Trade Mark Rights

Trade mark rights are territorial. A registration certificate issued by the Hong Kong Intellectual Property Department has no legal effect outside the Hong Kong Special Administrative Region. Mainland China operates its own independent trade mark system under CNIPA. A business that holds a Hong Kong registration but has not filed in mainland China has no enforceable rights there. If a third party registers the same or a similar mark with CNIPA first, the Hong Kong owner may be unable to use or enforce the mark in mainland China. This territorial principle applies regardless of the mark’s reputation in Hong Kong. Even a well-known Hong Kong brand must register separately in mainland China to obtain protection there.

Hong Kong Trade Mark Protection China

Hong Kong trade mark protection is limited to Hong Kong. The Intellectual Property Department examines applications. It publishes them for opposition. It registers marks that meet the requirements. The process follows the Nice Classification system. An application may cover multiple classes.

A Hong Kong registration does not prevent use or registration of the same mark in mainland China. Treat the two jurisdictions as entirely separate for trade mark purposes. Relying on a Hong Kong registration for mainland China protection is a common and costly mistake. File in mainland China if you sell products or services there, or plan to.

China Trade Mark Registration

China operates a first-to-file system. The first person or entity to file an application with CNIPA for a mark in a given class obtains the right to register it, regardless of who used the mark first. This differs from Hong Kong, where prior use may be considered during opposition proceedings.

China trade mark registration follows the Nice Classification but has its own examination standards. CNIPA examines applications for absolute grounds, distinctiveness and descriptiveness, and relative grounds, meaning conflict with earlier marks. If an application passes examination, it is published for opposition. The opposition period in China is three months from publication.

Delay filing in mainland China and you risk having your mark registered by a local entity or competitor. This is trade mark squatting. It is common in China. The only remedy is to oppose the application or seek invalidation. Both are costly and uncertain.

Hong Kong IP vs Mainland China

Hong Kong intellectual property law and mainland China law are separate legal systems. The key differences for trade marks are:

A Hong Kong trade mark registration cannot be used as a basis for a China application, except through the Madrid Protocol if the Hong Kong registration is a “basic mark” and China is a designated country. The Madrid route requires a home registration first, and the China application depends on the validity of the Hong Kong registration for five years.

First-to-File System in China

The first-to-file system in mainland China means priority matters. A business that files a trade mark application with CNIPA before any other party obtains the right to register the mark in the classes applied for. This applies even if the applicant has never used the mark.

Hong Kong also operates a first-to-file system, but the Intellectual Property Department may consider evidence of prior use during opposition. A Hong Kong applicant who has used a mark before a later filer can oppose the later application. In China, prior use is not a ground for opposing an application unless the mark is well known or the applicant acted in bad faith.

File in mainland China as early as possible. Ideally, file before launching products or services there. A China trade mark application can be filed based on a Hong Kong registration, but the filing date in China will be the date of the China application, not the Hong Kong filing date.

Examination and Opposition in Both Jurisdictions

Hong Kong trade mark examination is conducted by the Intellectual Property Department. The examiner checks whether the mark is distinctive, descriptive, or deceptive. If the application passes examination, it is published in the Hong Kong Intellectual Property Journal for three months. Any person may oppose the registration during this period.

China trade mark examination by CNIPA is more detailed. CNIPA checks for absolute grounds and searches for conflicting earlier marks. If CNIPA finds a conflict, it issues a provisional refusal. The applicant must respond within 15 months or the application is abandoned. If the application passes examination, it is published for three months. Any person may file an opposition.

The opposition process in both jurisdictions involves filing a notice of opposition, serving evidence, and attending hearings if necessary. In Hong Kong, the Intellectual Property Department handles oppositions. In China, CNIPA handles oppositions, and decisions may be appealed to the Beijing Intellectual Property Court.

Practical Advice for Businesses

File trade mark applications in both jurisdictions if your business operates in Hong Kong and mainland China. The Hong Kong application goes to the Intellectual Property Department. The China application goes to CNIPA. File them simultaneously or in any order.

If the business has a Hong Kong registration and wants to protect the mark in mainland China, file a China application as soon as possible. Waiting risks losing the mark to a third party.

The Madrid Protocol allows a Hong Kong trade mark owner to seek protection in multiple countries, including China, by filing a single international application. The international application must be based on a Hong Kong registration or application, and the protection in China depends on the validity of the Hong Kong registration for the first five years. After five years, the China registration becomes independent.

Consider the Nice Classification when filing. A mark registered in one class in Hong Kong does not cover other classes in mainland China. Tailor the specification of goods and services to the business’s actual activities in each jurisdiction.

Summary of Key Differences

• Hong Kong trade mark protection is limited to Hong Kong. Mainland China requires a separate registration with CNIPA.
• China operates a strict first-to-file system. Filing early is essential.
• Hong Kong examination considers prior use during opposition. China does not, except in cases of bad faith or well-known marks.
• Both jurisdictions use the Nice Classification and have three-month opposition periods.
• A Hong Kong registration cannot be enforced in mainland China. Separate filing is mandatory.
