Cases of refusal for trademark registration

Under the Law on Intellectual Property 2005, amended in 2009, 2019, 2022, and 2025 (hereinafter referred to as the Law on IP) and Circular 10/2026/TT-BKHCN, during the processing of a trademark registration application, the competent authority may refuse to accept the application or refuse to grant a protection title if the application fails to meet statutory conditions. Refusals can occur at various stages of the examination process, including the submission phase, formal examination, and substantive examination. Specifically:

Application submission stage

Pursuant to Clause 3, Article 70 of Circular 10/2026/TT-BKHCN, if an application lacks any of the minimum required documents, the receiving officer shall:

• Refuse to accept the application; or
• Send a notice of refusal to accept the application from the National Office of Intellectual Property to the applicant (if the application is filed via postal service or electronically via the online filing system).

For applications submitted via postal service that are refused acceptance, the National Office of Intellectual Property is not required to return the application documents to the applicant, except for original documents submitted for verification purposes.

Formality examination stage

According to Clause 2, Article 109 of the Law on IP, as guided by Article 71 of Circular 10/2026/TT-BKHCN, an industrial property registration application is deemed invalid in the following cases:

• The application does not meet the formal requirements;
• The subject matter stated in the application is an unprotectable subject matter;
• The applicant does not have the right to register, including cases where the registration right jointly belongs to multiple organizations or individuals, but one or more of them do not agree to the filing;
• The application is filed contrary to the regulations on filing methods;
• The applicant fails to pay the required state fees.

In these instances, the National Office of Intellectual Property will issue a notice on the formal examination results, explicitly stating the intention to refuse the application due to invalidity. The notice content typically includes:

• Name and address of the applicant;
• Name of the authorized representative (if any);
• Name of the subject matter stated in the application;
• Filing date and application number;
• Reasons and deficiencies leading to the intended refusal.

Simultaneously, the notice will set a time limit of 02 months from the date of issuance for the applicant to submit an opinion or correct the deficiencies.

Substantive examination stage (most important)

This is the decisive stage determining whether a trademark will be granted trademark protection. Common grounds for refusal include:

• The trademark does not meet the protection conditions
• The trademark is identical or confusingly similar
• The applicant lacks the right to register or registers with bad faith
• The application does not possess the earliest priority date
• There are multiple identical applications without consensus among applicants
• Amendments to the application alter the inherent nature of the trademark

Response process for refusal of trademark protection

• Response time limit: 02 months

• Accurately identify the root cause of the refusal
• Prepare clear legal arguments and evidence
• Possible handling methods include:
  • Explanation
  • Amending the scope of registration

Special crucial considerations for your trademark refusal appeal

Pay attention to the statute of limitations for appeals

The applicant must execute the appeal within the statutory time limit from the date of receiving or becoming aware of the contested decision or notice. Filing an appeal petition beyond this time limit can lead to the competent authority’s refusal to accept the case. Therefore, applicants must closely monitor notices from the National Office of Intellectual Property to promptly exercise their right to appeal.

Appeal arguments must have clear legal grounds

• In many instances, a refusal decision is issued because the trademark fails to meet protection conditions, has the potential to cause confusion with a previously registered trademark, or possesses descriptive characteristics.
• Thus, when conducting an appeal, the applicant must specifically analyze the relevant legal provisions, while concurrently providing arguments and evidence proving that the trademark still fulfills the conditions for trademark protection under the law.

Prepare comprehensive documents and supporting evidence

Evidence may include documents proving the trademark’s distinctiveness, evidence of actual trademark usage, comparative documents against cited marks, or other relevant materials.

Preparing sufficient and appropriate evidence will reinforce the appeal arguments and increase the likelihood of acceptance.

Consider utilizing specialized intellectual property legal consulting services

Appeal procedures in the industrial property sector frequently demand deep comprehension of legal regulations as well as practical examination practices at the competent authority.

Consequently, engaging the services of an industrial property representation organization or an experienced legal consulting unit will assist in accurately evaluating the appeal viability, constructing an appropriate argumentative strategy, and mitigating potential legal risks.
