In China’s trademark registration process, understanding the deadlines for filing a refusal review (also known as a trademark re-examination) is crucial for protecting your trademark. When the China National Intellectual Property Administration (CNIPA) rejects a national trademark application (or a Madrid international application) via electronic means, specific rules apply to calculate the 15-day filing window.
This guide breaks down the electronic delivery (data message) rules under the Trademark Law of China and its Implementing Regulations, including key examples, holiday extensions, and best practices. Whether you’re a business owner, IP attorney, or applicant, mastering these timelines can prevent missed opportunities.
Key Legal Foundations for Trademark Rejection Review Deadlines
These rules ensure fairness in the digital age, but they demand proactive monitoring of the CNIPA’s online system.
How to Calculate the 15-Day Deadline Under Electronic Delivery
Step 1: Determining the Receipt Date
In electronic trademark applications submitted via the CNIPA Trademark Online Service System, rejection notices are uploaded as data messages. The receipt date is calculated from the 15th day after upload.
Step 2: Starting the Clock on the 15-Day Window
The review filing deadline begins the day after the receipt date and runs for 15 calendar days. Use these formulas for precision: Upload Date + 15 Days = Receipt; Receipt + 15 Days = End.


Holiday and Weekend Extensions: What Counts as a Holiday?
Under the Implementing Regulations, if the 15-day deadline ends on a holiday, it automatically extends to the first working day after. Key points:
- Holidays include Saturdays, Sundays, and official Chinese public holidays (e.g., National Day, Spring Festival).
- No manual request needed—it’s automatic.
- Always verify CNIPA’s holiday calendar for accuracy, as it impacts your filing timeline.
For instance, if your deadline falls during Golden Week (October 1-7), it shifts post-holiday (i.e., October 8th), giving you extra breathing room.
If you are afraid of a mistake in calculating the holiday, we strongly advise you to submit the review within the 30-day deadline.
Conclusion: Secure Your Trademark Rights with Timely Action
Calculating trademark rejection review deadlines under electronic delivery in China is calculated by 15 days + 15 days + holidays (if applicable) from upload dates. Missing the appealing window can forfeit your rights, so prioritize proactive management. For official guidance, refer to CNIPA’s resources or consult experts. Stay informed to protect your brand in one of the world’s largest markets.
