Trademark Opposition in Vietnam: 8 Issues for Businesses

A conflicting trademark application can affect sales and distribution plans in Vietnam. The brand owner needs to decide whether to oppose registration. The applicant needs to answer the grounds and protect the goods or services its business needs.

Trademark opposition in Vietnam allows a third party to challenge a pending national application before registration. The Intellectual Property Office of Vietnam (IP Vietnam) considers the objection during examination. The process concerns registration; a demand to stop sales or pay compensation requires a separate assessment of infringement.

Monitoring applications and keeping evidence of ownership and use are part of managing intellectual property in Vietnam. Bring together the records held by head office, local staff and the IP representative before deciding how to proceed.

Quick Reference

A formal opposition to a national application must be filed within three months from publication in the Industrial Property Gazette, in Vietnamese, with supporting documents or information sources and the required fees. An applicant answering under the current procedure ordinarily has one month from IP Vietnam’s notice date. Confirm the procedure for an older file. Prepare evidence and translations early.

Trademark Opposition in Vietnam: 8 Issues for Businesses

Confirm the Application and the Opposition Deadline

Start with the application number, applicant’s name, mark, goods and services, filing or priority date, and publication record. Applications are made publicly available after receipt, but the opposition period starts with publication in the Industrial Property Gazette. That publication is due within one month after the application is accepted as formally valid. Use the Gazette date to calculate the deadline.

A trademark search in Vietnam helps identify conflicting applications and earlier rights. Continue monitoring after the search. Give one person responsibility for passing new findings to the IP representative and obtaining a decision about action.

Once the formal opposition window has closed, third-party observations may still be submitted before a grant decision. These provide information for examination and follow a different procedure. After grant, assess a complaint against the grant decision or a request to invalidate the registration. Check the file’s status and the deadline for the proposed route.

Choose Grounds that the Evidence Can Support

Any third party may file an opposition, but the objection needs a legal basis. An earlier application or registered mark can support an objection to an identical or confusingly similar mark for identical or similar goods or services. Compare the marks’ appearance, sound and meaning, and explain how the goods or services relate. Different class numbers alone do not settle that question.

Earlier use can also matter where the law protects a mark that was already widely used and recognized, or a well-known mark. Those grounds require evidence of the recognition relied on. A foreign registration alone does not create trademark rights in Vietnam. An existing trade name can also be relevant where the legal conditions are met.

Other grounds concern whether the mark qualifies for protection at all, including descriptive or misleading signs. An opposition may also challenge the applicant’s right to register or allege bad faith. If a distributor has applied to register the owner’s mark without permission, examine the relationship, authorization and applicable treaty conditions. A damaged business relationship alone proves neither lack of entitlement nor bad faith.

Build an Evidence File around Each Ground

For an earlier-rights objection, collect the application or registration records and check their owner, dates, current status and goods or services. Explain which parts of the later application conflict with those rights, using a clear comparison supported by the relevant records.

For claims based on use or recognition, organize dated sales records, invoices, advertising, distribution records and other reliable material. Show what each document establishes about the mark, the market and the period concerned. Evidence from after the applicant’s filing date needs an explanation of how it supports the earlier position relied on.

Where a distributor or former partner is involved, preserve the contract, brand instructions, permissions and complete communications. These records may also become evidence for contract disputes in Vietnam. Keep originals and the source details of online material, including dates and full message threads. Court proceedings have their own evidence requirements.

The opposition itself must be in Vietnamese. Supporting material in another language must be translated when IP Vietnam requests it. Prepare translations of the main documents early so that the argument and the evidence can be checked together.

File Through the Correct Party and IP Representative

The submission should identify the application being opposed, the opponent, the grounds, supporting evidence and the requested outcome. Be clear whether the objection concerns all the listed goods and services or only some of them. Arrange the required fee payment and keep proof of filing.

Foreign organizations without a production or business establishment in Vietnam, and foreign individuals who are not permanent residents, must use a qualified industrial property representation service organization for the procedure. The term IP representative refers here to that qualified provider. A distributor or a person holding a general authorization may lack the qualification needed to make the filing.

Confirm who will sign the power of attorney and whether its scope covers the opposition. Give the IP representative the complete records early enough to prepare the Vietnamese submission. Approval by head office and an email to the IP representative are internal steps; obtain confirmation that IP Vietnam has received the filing.

Answer an Opposition with a Focused Response

An applicant should send the complete notice and opposition materials to its IP representative as soon as they arrive. Under the current ordinary procedure, the response period is one month from the notice date. Time spent forwarding the notice between local staff and head office reduces the time available for drafting. For an older file, confirm which procedural rules apply before calculating the deadline.

Address each ground. For an earlier-mark objection, explain the differences that affect the risk of confusion and check the earlier right’s status. For a claim of earlier recognition, examine whether the evidence establishes recognition in the relevant market and period. For an allegation of an unauthorized filing, provide the ownership, permission and relationship records that answer it.

The business may consider removing goods or services that it no longer needs, provided the amendment stays within the permitted scope. Check the proposed wording against the products it actually sells and plans to sell before approving a deletion.

The applicant can request one extension of its reply period, equal to the original period, by filing a written request before expiry and paying the prescribed fee. This does not extend the three-month period for filing an opposition.

Follow the Procedure and any Court Referral

For a qualifying opposition under the ordinary current procedure, IP Vietnam has one month from receipt to notify the applicant. If needed, IP Vietnam then sends the applicant’s response to the opponent and allows one month from that notice date for a reply. Certain clear cases are dealt with directly during substantive examination. A dialogue can be arranged if IP Vietnam considers it necessary or both parties request it.

Some disputes over who has the right to register need a court decision. If IP Vietnam directs the opponent to bring that dispute to court, the notice sets two months to provide a copy of the court’s notice accepting the case. Filing a claim with the court is only part of the work; the required proof of acceptance must reach IP Vietnam in time. Certain entitlement cases can instead be decided during examination.

When the court acceptance notice is submitted in time under this procedure, IP Vietnam suspends the application pending the court’s effective judgment or decision. Without it, the opposition is treated as withdrawn and examination continues. Coordinate the IP filing and court work from the start so that responsibility for each document is clear.

Consider Settlement alongside the Filing Response

An agreement may resolve the commercial conflict through a narrower list of goods or services, withdrawal of an application, or agreed terms for use of the mark. First identify what each party needs in Vietnam and who has authority to make the agreement. Before contacting the other side, assess whether existing sales could expose the business to an infringement claim.

A contract review should cover the exact mark, permitted activities, filing steps, payment conditions and what happens if registration is refused. Withdrawal of an opposition or a consent letter leaves IP Vietnam responsible for assessing whether the application meets the legal requirements.

Continue preparing any response or extension request while talks take place. Agree who will submit each procedural request and obtain the filing confirmation. An agreed commercial timetable does not change IP Vietnam’s deadlines.

Plan for the Result and the Effect on the Business

The opponent receives the opposition result with the corresponding substantive examination result. An objection may affect only part of the goods or services, so read the result against the protection the business needs.

The three-month opposition window is a filing period, not a completion timetable. The applicant’s response time and the opponent’s reply time are excluded from the substantive examination period. A court referral can cause a longer pause. Budget for the next procedural stage and update launch or distribution plans when there is reliable information about the file.

For an applicant, a notice inviting a response and a final refusal require different action. After grant, a directly affected party should assess an administrative complaint against the grant decision or an invalidation request. The ordinary first-complaint deadline is 90 days from receipt or knowledge of the decision, subject to statutory exceptions.

Registration and actual use also need separate decisions. Filing an opposition does not itself stop the applicant’s sales. Continuing use may still infringe an earlier right, so assess that risk before approving new packaging, advertising or stock commitments.

Madrid Designations Need a Separate Deadline Check

An international registration designating Vietnam under the Madrid System needs a separate check of the available procedure and deadline. The rules expressly allow third-party comments as information for examination. The period starts with WIPO publication and ends before Vietnam accepts protection, or when 12 months have passed from WIPO’s notification of the Vietnam designation, whichever comes first. Have the IP representative confirm whether a formal opposition is also available and calculate its deadline separately.

If the holder receives a provisional refusal through WIPO, the response follows the Madrid refusal procedure. Send the complete notification to a qualified IP representative in Vietnam and have its response deadline confirmed promptly.

Preparing an Opposition or Response

1. Confirm the national application or Madrid designation, its current status and the publication or notice date that starts the relevant period.

2. Agree on the grounds and the desired result. Gather the records, arrange authorization and prepare the Vietnamese submission and necessary translations.

3. For a national opposition, file within three months from publication in the Industrial Property Gazette and pay the required fees. Keep the filing receipt and submitted documents.

4. For an applicant’s response under the current ordinary procedure, work to one month from IP Vietnam’s notice date. Request any permitted extension before the period expires.

5. Review each later notice. If a court referral requires proof that the case has been accepted, organize that work immediately and track the separate two-month period.

Frequently Asked Questions About Trademark Opposition in Vietnam

Q1: Can a business oppose without a Vietnamese trademark registration?

Yes. Any third party can file an opposition, but it must establish a legal ground. Earlier use or recognition, lack of entitlement, bad faith or failure to meet protection conditions require supporting evidence. An overseas registration by itself is insufficient.

Q2: Can an application still be challenged after the opposition deadline?

Yes, the route depends on the application’s status. Before grant, third-party observations can provide information for examination. After grant, assess a complaint against the grant decision or an invalidation request. Check the complaint deadline promptly.

Q3: Does an opposition automatically stop registration or sales?

No. IP Vietnam considers the objection as part of deciding whether to grant protection. A qualifying court referral can suspend the application. Restrictions on sales require a separate legal basis and procedure.

Q4: Does missing the applicant’s reply mean the opponent wins?

No. IP Vietnam must assess the grounds and available evidence. Silence alone does not establish that the opposition is justified, but failing to reply leaves the applicant’s response out of that assessment.

Conclusion

Before approving an opposition or response, confirm the grounds, evidence and protection the business needs. Assign responsibility for each filing, including any court work, and keep those deadlines in view during commercial negotiations.
