Introduction: the six-month window most foreign applicants never use

A foreign applicant that has filed a trademark in its home country has, in principle, a six-month opportunity to secure the benefit of that earlier filing date in China. The mechanism is a priority claim, and it is available under the Paris Convention route as well as under Chinese law itself.

The window is short, the requirements are formal, and the failure mode is quiet: an applicant that does not make the claim properly simply does not get the earlier date, and often does not discover that until a citation is raised against the Chinese application.

The right itself

Where an applicant files a trademark registration application in China within six months of filing the same mark for the same goods or services in a country that is a party to the relevant convention, or under a treaty to which both countries are parties, the applicant may claim priority based on the earlier filing.

A separate priority exists for marks first used on goods exhibited at an international exhibition sponsored or recognised by the Chinese government. That priority runs for six months from the date the goods were exhibited.

The effect of a valid priority claim is that the Chinese application is treated, for the purposes of conflicting earlier rights, as having been filed on the date of the first application. That is the whole benefit, and it is a significant one: it can move an application ahead of a third-party filing made in the interim.

How the claim is made

The priority claim is made in the application itself, by completing the priority section of the request. The applicant identifies the country or region of the first filing, the filing date, and the application number.

Two formal obligations attach. The applicant must submit the priority document — the certificate of the earlier filing — and where that document is not in Chinese, a Chinese translation. Where the priority document cannot be filed at the same time as the application, the applicant may elect to file it later, and must then submit it within three months from the date of the Chinese application.

The consequences of getting this wrong are set out plainly in the rules. Where the written declaration is not made, or where the priority document is not submitted within the period, the priority claim is treated as not having been made. There is no discretionary extension.

Multiple first filings in the same country

A situation that arises for foreign applicants applying under a single-class system abroad. Suppose an applicant filed the same mark in the same country on the same day across several classes, under separate national applications. Can it claim priority in a Chinese multi-class application?

Yes. Where priority is claimed, the applicant may base it on multiple first filings in the same country, on the same filing date, for the same mark, listing each earlier application number in the relevant field and submitting the priority documents for all of them.

This is a useful option, because Chinese practice permits a single application covering multiple classes. An applicant with a fragmented foreign filing can consolidate it into one Chinese application without losing the priority benefit.

Exhibition priority

Where priority is based on an exhibition, the applicant selects the exhibition-based priority option and completes the country or region of exhibition and the date of exhibition. The applicant must also submit the priority document, including the original and a Chinese translation, or elect to file it later within the same three-month period.

The priority document in this case must show the name of the exhibition at which the goods were exhibited, evidence that the mark was used on the exhibited goods, and the exhibition dates. It is generally issued or certified by the exhibition organiser.

This route is narrower than the Paris Convention route and is used relatively rarely, but where a brand is launched at a qualifying exhibition it can secure a date that would otherwise be lost.

The relationship with the home application

A point that often causes confusion: the Chinese application is a separate application, not an extension of the home filing. The priority claim gives it the benefit of the earlier date for the limited purposes the law provides. It does not make the Chinese application part of the home application, and it does not mean that the home filing's prosecution or its outcome binds CNIPA.

The Chinese application is examined on its own terms, against the Chinese register, applying Chinese law. Priority affects the date, not the standard.

What priority does and does not protect against

It is worth being precise about the scope of the benefit, because applicants sometimes expect more than priority delivers.

It does protect against third-party filings in the interim. A third party that files the same or a similar mark in China between the home filing date and the Chinese filing date will normally be met by a citation based on the priority date.

It protects the date for the purposes of the applicant's own earlier rights. Where the applicant itself has an existing Chinese registration or application, the priority date is the date that counts in assessing the relationship.

It does not cure a defect in the mark itself. If the mark is descriptively weak in relation to the goods, or if it has an adverse effect, priority does not change that analysis. The mark is examined on its merits, on an earlier date.

It does not extend the priority period. The six months runs from the first filing, and it is not extendable. Where a foreign applicant has filed in several jurisdictions and intends to build a Chinese portfolio, the six-month point is the deadline that governs the whole exercise.

Two date traps

The first is a calculation error. The six months runs from the date of the first filing, and the Chinese application must be filed within it. Applicants who treat the window as running from the grant of the home registration, or from a later foreign filing, are working from the wrong date.

The second is a documentation error. The declaration may be made correctly and the priority document then forgotten, or filed outside the three-month period. Because the consequence is that the priority claim is treated as not having been made, the failure is invisible until an examiner raises a citation that priority would have defeated. By then the window has closed.

The practical discipline is to treat the priority document as a deliverable with its own deadline, tracked separately from the application itself, and to verify that it has been filed and accepted rather than assuming that instructing the agent was sufficient.

Frequently asked questions

How long is the priority window for a Chinese trademark application?

Six months from the first filing of the same mark for the same goods or services in a qualifying country. A separate six-month priority exists for marks first used at an international exhibition sponsored or recognised by the Chinese government.

How do I claim priority in China?

Complete the priority section of the Chinese application, identifying the country or region, the filing date and the application number, and submit the priority document with a Chinese translation.

What if I cannot file the priority document immediately?

You may elect to file it later, but it must be submitted within three months from the date of the Chinese application. Where it is not, the priority claim is treated as not having been made.

Can I claim priority from several foreign applications at once?

Yes. Where you filed the same mark on the same day in the same country across several single-class applications, you may base the Chinese multi-class application on all of them, listing each application number and submitting the priority documents for all.

Can an exhibition give me priority?

Yes, where the mark was first used on goods exhibited at an international exhibition sponsored or recognised by the Chinese government, within six months of the exhibition date. The priority document must show the exhibition name, the use of the mark on the exhibited goods and the exhibition dates.

Does priority make my Chinese application part of my home application?

No. The Chinese application is separate and is examined under Chinese law against the Chinese register. Priority gives it the benefit of the earlier date; it does not import the home prosecution.

What happens if I miss the three-month evidence period?

The priority claim is treated as not having been made. The Chinese application proceeds with its own filing date, which may expose it to third-party filings made in the meantime.
