A trademark is one of the most critical intellectual property assets for a business, functioning to distinguish goods and services while supporting brand value development in the market. After trademark registration is granted, information regarding the owner, address, protection title holder, or scope of protection may change during business operations.
When a change falls under legally permitted circumstances, the title holder must carry out procedures to update the information, ensuring that the records at the National Office of Intellectual Property align with the actual legal status. In this article, Viet An Law updates the latest regulations of 2026 on the amendment of trademark registration certificate in Vietnam, covering the dossier, procedure, processing time, and relevant fees.
Legal basis to amend trademark protection title in Vietnam
The current legal regulations related to the procedure to amend trademark registration certificate vietnam include:
- Law on Intellectual Property 2005 and amending and supplementing laws in 2009, 2019, 2022, 2025, notably Law No. 131/2025/QH15 effective from April 1, 2026;
- Decree No. 65/2023/ND-CP and amending and supplementing documents in 2026;
- Circular No. 10/2026/TT-BKHCN dated March 31, 2026;
- Circular No. 20/2026/TT-BKHCN dated May 20, 2026, in which the intellectual property provisions in Chapter IV take effect from July 1, 2026;
- Circular No. 263/2016/TT-BTC on industrial property fees and charges and amending and supplementing documents;
- Decision No. 2735/QD-BKHCN in 2026 announcing administrative procedures in the field of intellectual property.
The amended Vietnamese Law on Intellectual Property 2025 has amended Article 97 on the amendment of protection titles and assigned the Minister of Science and Technology to detail the implementation order and procedure.
What is a trademark registration certificate in Vietnam?
A trademark registration certificate is a protection title issued by the National Office of Intellectual Property to organizations and individuals possessing a trademark that meets the protection conditions under legal regulations. The title records basic information such as the trademark owner, trademark sample, list of protected goods and services, and protection term.
The certificate is the legal basis establishing the owner’s industrial property rights over the trademark within the protected scope. When the information recorded on the title changes, the owner must implement modification of trademark registration vietnam according to regulations.
Permitted cases for amending a trademark registration certificate in Vietnam
According to Article 97 of the Vietnamese Law on Intellectual Property amended in 2025 and current guiding documents, the requirement to amend trademark protection title may arise in the following cases:
Change of name or address of the trademark owner
An enterprise may change its company name, head office address, or an individual may change information related to the address recorded on the protection title.
In this case, the title holder can request the National Office of Intellectual Property to update the trademark certificate Vietnam accordingly to reflect the exact new information.
According to the new regulations in 2026, regarding name and address information, the National Office of Intellectual Property can proactively exploit information from the database published by the competent authority. In case the data cannot be exploited or is incomplete and inaccurate, the dossier processing agency will request the applicant to supplement proving documents.
Change of protection title owner
The trademark owner may change due to:
- Inheritance or succession;
- Merger, consolidation, division, or separation of enterprises;
- Conversion of enterprise type;
- Establishment of a new legal entity by the same owner;
- Decision of a Court or competent state authority;
- Trademark assignment;
- Other lawful ownership transfer cases.
The 2026 regulations have more clearly integrated the amendment of protection titles due to the IP assignment of industrial property rights into the protection title amendment procedure.
Amendment of regulations on the use of collective trademarks or certification trademarks
For collective trademarks and certification trademarks, the title holder has the right to request an amendment to the usage regulations recorded when the title was granted.
This case may require re-examination of the corresponding content, so the re-examination time is not included in the normal processing time of the amendment dossier.
Narrowing the scope of trademark protection
The owner may request to:
- Reduce one or several goods and services;
- Remove one or several classes of goods and services from the protected list;
- Remove a minor detail that is an excluded element, not separately protected, provided it does not alter the distinctive character of the trademark.
It should be noted that the amendment procedure only allows narrowing the protection scope and is not a procedure to add new goods and services to the granted title.
Correction of errors on the protection title
If the trademark registration certificate contains errors, the title holder may request correction.
If the error is due to the fault of the National Office of Intellectual Property, this agency is responsible for the correction, and the title holder does not have to bear the corresponding fees and charges. If the error stems from information provided by the title holder, the requester must pay the fee as prescribed.
Dossier for amendment of trademark registration certificate in Vietnam
Under current procedures, the dossier is prepared in 01 set.
Depending on the amended content, the dossier may include:
Declaration for amendment of protection title
Use Form No. 02 Appendix II issued alongside Circular No. 20/2026/TT-BKHCN.
One declaration can request the amendment of multiple protection titles of the same type if they share the same amended content, the same transferee, and the requester pays the full fee for each title.
Original trademark registration certificate
Submit the original if the protection title was issued in paper form and the procedure requires recording the amended content on the paper title.
Documents proving the change of name or address
These may include: An enterprise registration certificate recording the new name or address; a decision on changing the name or address, or other legal documents proving the change.
Under the new mechanism, if the National Office of Intellectual Property can fully exploit information from the state database, the requester may not have to re-supply documents that the state agency already possesses.
Documents proving the change of owner
In cases where the title owner changes due to inheritance, merger, consolidation, division, separation, enterprise conversion, or other forms of ownership transfer, there must be documents proving the corresponding transfer basis. This is essential when businesses change trademark owner vietnam.
Dossier for trademark assignment cases
In case the title owner changes due to a trademark assignment, the dossier may include: An industrial property assignment contract; a Vietnamese translation if the contract is made in another language; a written consent from co-owners if the trademark is jointly owned; a document from the mortgagee if the industrial property right is being used as collateral, and relevant documents depending on the case.
For collective trademarks or certification trademarks, specific conditions regarding the transferee and the regulations on using the trademark must also be met.
Documents for amending the protection scope or trademark sample
Depending on the specific request, the dossier may need:
- Detailed explanatory documents on the amended content;
- 02 copies of the amended regulations on the use of collective trademarks or certification trademarks if submitting a paper dossier;
- 05 trademark samples if requesting to amend the trademark sample in cases permitted by law;
- Documents showing the scope of goods and services proposed for reduction.
Power of attorney
If the dossier is submitted through an industrial property representation organization such as Viet An Law, a power of attorney is required as prescribed.
Where to submit the protection title amendment dossier in Vietnam?
According to the administrative procedures announced in 2026, the dossier can be submitted through one of the following methods:
- Online submission: through the administrative procedure resolution information system of the Ministry of Science and Technology.
- Direct submission or via postal service: to the Ministry of Science and Technology.
The agency directly resolving the procedure is the National Office of Intellectual Property. Therefore, to update trademark certificate Vietnam properly, applicants must follow these current administrative procedures rather than the outdated guidance of submitting at previous regional offices.
Processing procedure for requests to amend a trademark registration certificate
Step 1: Determine the content to be amended
The title holder must clearly determine whether the change falls under the change of name or address; change of owner; assignment; amendment of regulations; narrowing of protection scope, or correction of errors.
Correctly identifying the case from the beginning helps in selecting the right proving documents and the required fees to pay.
Step 2: Prepare and submit the dossier
The requester completes the declaration according to the current form and submits it along with the corresponding documents.
Certain cases, such as IP assignment, collective trademarks, certification trademarks, or narrowing the protection scope, require a more complex dossier compared to a regular change of name or address.
Step 3: The National Office of Intellectual Property examines the dossier
The resolution time limit in principle is 02 months from the date of receiving the dossier, excluding the time for the applicant to correct errors and the time to conduct re-examination in cases prescribed by law.
If the dossier is valid, the National Office of Intellectual Property issues a decision to amend the protection title, records the information, and enters it into the register.
If the dossier contains errors or is invalid, the Office issues a notice of intended refusal, clearly stating the reasons, and sets a 02-month time limit for the requester to correct the errors or submit opposing opinions.
In case the time limit expires and the requester fails to remedy the situation or the remedy is unsatisfactory, the Office may issue a decision refusing the amendment request.
Step 4: Publish the amended information
Under the current procedures in 2026, the amendment decision is published in the Industrial Property Official Gazette as prescribed.
The publication period is now determined as 30 days from the date of issuing the decision, replacing the 60-day milestone reflected in older regulations.
Resolution time limit for trademark amendment procedures in Vietnam
The standard processing time is 02 months from the date of receiving the dossier.
However, this time does not include:
- The time for the requester to correct or supplement the dossier;
- The time to conduct re-examination in the case of amending the regulations on the use of collective trademarks or certification trademarks;
- The re-examination time when narrowing the protection scope;
- Certain cases of assigning collective trademarks or certification trademarks.
Therefore, in practice, the completion time may be longer than the 02-month limit depending on the type of request and the dossier’s status.
State fees for amending a trademark registration certificate in Vietnam
According to the administrative procedures announced in 2026, some basic fees include:
| Content | Announced fee level |
| Fee for examining the protection title amendment request | 160,000 VND/title |
| Fee for examining the amendment due to industrial property assignment | 230,000 VND/title |
| Fee for registering the amendment decision | 120,000 VND/title |
| Fee for publishing the amendment decision | 120,000 VND/dossier |
| Fee for examining the narrowing of trademark protection scope | 550,000 VND/class of goods and services |
| Re-examination fee for amending regulations on collective/certification trademarks | 550,000 VND/class |
For regular changes of name or address, state management agencies currently guide that the total basic fees are approximately 400,000 VND per title, corresponding to the examination, registration, and publication fees.
The case of assigning a part of the list of goods and services may also incur a fee for granting a trademark registration certificate and other search and examination fees.
In 2026, there are several policies on fee and charge exemption and reduction when performing public services via VNeID. Specifically, for cases subject to protection title issuance, the title issuance fee when executing via VNeID is exempted from April 1, 2026, to the end of December 31, 2026, according to the applied regulations. This provides a great opportunity to complete the modification of trademark registration vietnam at a lower cost.
Some notes when updating information on the trademark registration certificate in Vietnam
- The amendment procedure cannot be used to expand the protection scope. If an enterprise wishes to add new goods and services not included in the granted title, in principle, it must carry out a new trademark registration for the new scope.
- Not all logo changes are directly amended on the title. Removing a minor detail is only accepted when it is an excluded element, not separately protected, and the removal does not alter the distinctive character of the trademark.
- It is necessary to distinguish between changing the owner and changing the owner’s name. If the legal entity remains the same subject but changes its enterprise name, this is an amendment to the title owner’s information. If ownership transfers to a different subject, it is necessary to determine the basis for the transfer or assignment of rights.
- For enterprises with multiple trademarks, it is possible to request the amendment of multiple titles in one declaration if they meet the conditions of the same type of object, the same amended content, and the same transferee; however, the fee is still calculated for each title as prescribed. To amend a trademark registration certificate in Vietnam properly, businesses must review these conditions.
Can an amendment be made if the original trademark registration certificate is lost in Vietnam?
In cases where the title was issued in paper form but is lost, the requester should note that the title re-issuance procedure and the amendment procedure are two different procedures by nature.
According to the guidance of the Ministry of Science and Technology in 2026, from July 1, 2025, the protection title re-issuance procedure falls under the reception and processing scope at the provincial level under the decentralization mechanism. When concurrently performing an amendment, the dossier must reflect the status of undergoing the re-issuance procedure according to the guidance of the competent authority.
Is it possible to add products and services to a granted trademark in Vietnam?
No. The protection title amendment procedure allows the owner to reduce goods, services, or classes of goods and services within the protected scope, but it is not a procedure to add a new protection scope.
If an enterprise develops additional products or services and wants the trademark to be protected for those products and services, it must consider filing a new trademark registration application for the corresponding scope.
