Errors on the registration certificate fall into two situations: where the right holder's own circumstances have changed, file a change application; where the certificate itself contains a clerical or data-entry error, apply for correction. The two procedures are different and must not be confused.
Change: Changes in Name, Address, or Other Matters
Under Article 41 of the Trademark Law, where a registered trademark requires a change in the registrant's name, address, or other registered matters, a change application must be filed. After a company rename or relocation, the change should be completed promptly; otherwise it may affect the delivery of official documents and evidence in enforcement, and in serious cases may even lead to the trademark being revoked.
Correction: Errors on the Certificate Itself
Where the registration certificate contains an obvious clerical error, typo, or system entry error that does not concern the substance of the registration, you may file a correction application with the CNIPA together with supporting materials. Where the error results from the CNIPA's own mistake, the CNIPA will correct it ex officio and reissue the electronic certificate.
What Cannot Be Changed
- Trademark device: it must not be altered on your own; if modification is needed, a new registration application must be filed;
- Approved goods: in principle they cannot be reduced, altered, or expanded; new items require a separate application;
- After obtaining the certificate, always check each item of information and address any problem as early as possible.
If you are unsure about any of the above, you can first arrange trademark agency registration through MyTMBee and act after a recorded agent provides an analysis.
