For businesses expanding their brands globally, understanding and utilizing China's trademark priority rights system is a crucial strategy. It provides a critical time advantage and serves as a primary defense against trademark squatting when entering the Chinese market. This guide offers international readers a clear and actionable roadmap.
Why Are Priority Rights Essential?
The priority right principle, based on the Paris Convention, offers two key strategic advantages in China. First, it provides a Time Buffer. From the date of your first trademark application in a member country (or a jurisdiction with a reciprocal agreement with China), you have six months to file in China, with your Chinese filing date being recognized as that initial foreign date. Second, it helps Prevent Squatting by effectively blocking others from registering identical or similar marks in China during that six-month window, securing your brand's legal foundation for market entry.
How to Claim Priority Rights in China
China's trademark priority system primarily consists of two types. The operational process is summarized in the flowchart below, providing a clear overview.

Step 1: Prepare the Application and Complete the Declaration
Within the application system of the China National Intellectual Property Administration (CNIPA), you must actively declare your claim for priority rights upon submission. For a claim based on a first application, select "Priority based on the first application" and accurately fill in the country/region, application date, and application number of that first filing. For a claim based on exhibition use, select "Priority based on exhibition" and fill in the exhibition country/region and the date the goods were first displayed.
Step 2: Prepare and Submit the Supporting Documents
Supporting documents are crucial and must be submitted within the statutory timeframe. For a claim based on a first application, you need a certified copy from the original trademark office stating the filing date and number, accompanied by an accurate Chinese translation. For exhibition-based claims, a certificate from the organizer of a Chinese government-hosted or recognized international exhibition is required, detailing the exhibition name, date, and evidence of use, also with a Chinese translation.
Regarding submission, the ideal scenario is to file these documents simultaneously with your Chinese application. If that's not possible, you may select the "Priority document to be submitted later" option. However, you must supplement the documents within three months from the Chinese application date; failure to do so will result in the abandonment of the priority claim.
Strategies for Common Complex Scenarios
Scenario 1: Single Foreign Multi-Class Application for Multiple Chinese Filings
If your initial foreign application covers multiple classes but you plan to file several single-class applications in China, you can submit the original priority document with just one Chinese application. For all other related applications, simply indicate the application number containing the original document. If filing the priority document later, include a statement listing all associated Chinese application numbers.
Scenario 2: Multiple Foreign Single-Class Applications for One Chinese Multi-Class Filing
If you filed multiple single-class applications abroad for the same trademark on the same day but wish to submit one multi-class application in China, you must list each foreign application number individually in the form and submit all corresponding priority documents.
Key Reminders for International Applicants
First, strictly adhere to the two non-extendable deadlines: the six-month priority period and the three-month document supplementation period. Plan ahead for document procurement and translation. Second, ensure the trademark and designated goods/services are essentially identical to the original foreign application; the scope can be narrowed but not expanded. Third, for exhibition claims, confirm the event's status as officially recognized by China.
Due to the procedural complexity, engaging an experienced Chinese trademark agent is highly recommended to avoid formal deficiencies that could lead to a loss of rights.
To conclude, China's trademark priority rights system is a vital legal instrument for the efficient and secure entry of international brands. By accurately understanding the rules and planning meticulously, you can leverage this system to build a robust intellectual property shield for your brand.
