How to Oppose a Trade Mark Application in Singapore
Discovering that another business has applied to register a trade mark that is identical or similar to your brand can be concerning, especially if the proposed registration could affect your existing business, reputation or future expansion.
In Singapore, once the Intellectual Property Office of Singapore, or IPOS, accepts a trade mark application, the application is published in the Trade Marks Journal. From the publication date, there is generally a two month period during which a third party may oppose the registration.
To commence a trade mark opposition, the opponent generally files Form TM11 together with a statement of grounds, pays the applicable filing fee and serves the required documents on the trade mark applicant.
As at August 2026, the official IPOS filing fee for Form TM11 is S$420 for each class opposed.
A trade mark opposition is a formal legal proceeding. Before filing, it is important to determine whether there are proper grounds for opposition, what evidence is available and whether opposition is the most appropriate commercial strategy.
Key Takeaways :
- A Singapore trade mark application may generally be opposed after IPOS has accepted and published it in the Trade Marks Journal.
- The normal opposition period is two months from the publication date.
- An opposition is commenced using Form TM11 together with a statement of grounds.
- The current official filing fee is S$420 for each class opposed.
- The opponent should identify the legal grounds and supporting facts clearly rather than simply alleging that the marks are similar.
- The trade mark applicant generally has two months after receiving the opposition to file a counter statement using Form HC6.
- The proceedings may involve evidence, settlement discussions, mediation, written submissions and a hearing before IPOS.
- If the mark has already been registered, opposition is generally no longer the appropriate procedure. Invalidation or revocation may need to be considered instead.
When Can a Trade Mark Application Be Opposed?
A trade mark opposition takes place after an application has completed the examination stage but before registration is finalised.
When IPOS considers that an application satisfies the applicable registration requirements, the application is accepted and published in the Trade Marks Journal.
Publication gives third parties an opportunity to challenge the proposed registration.
Opposition may therefore become relevant where:
- The application has passed examination.
- IPOS has accepted the application.
- The application has been published in the Trade Marks Journal.
- The opposition period has not expired.
- A third party believes there are legal grounds to prevent registration.
Â
The fact that IPOS has accepted an application does not necessarily mean that no one else can challenge it.
For example, an examiner may not be aware that another business has used a similar unregistered brand in Singapore for many years. IPOS may also not have information regarding a previous commercial relationship between the applicant and another party, such as a distributorship, agency arrangement or partnership.
These circumstances may only become relevant when a third party brings them to IPOS’s attention through opposition proceedings.
Trade Mark Opposition vs IPOS Objection, Invalidation and Revocation
Several procedures can affect a Singapore trade mark application or registration. They serve different purposes and arise at different stages.
Procedure | When it is used | Usually initiated by |
Examination objection | During IPOS examination | IPOS |
Trade mark opposition | After publication but before registration | Third party |
Invalidation | After the trade mark has been registered | Interested party |
Revocation | After registration, including certain non use situations | Interested party |
Â
An IPOS examination objection is raised by an examiner while reviewing a trade mark application.
A trade mark opposition is brought by another person after IPOS has accepted and published the application.
An invalidation application generally seeks to establish that a registered trade mark should not have been registered.
A revocation application may arise where circumstances occurring after registration justify removal of the trade mark from the register, including certain situations involving non use.
Choosing the correct procedure is important because different forms, deadlines, grounds and evidential requirements apply.
Why Businesses Should Monitor the Trade Marks Journal
Businesses that rely heavily on their brands should consider monitoring newly published trade mark applications.
Waiting until a conflicting mark has already been registered may make the dispute more complicated and potentially more expensive.
Monitoring should also go beyond searching for an exact copy of the brand.
Depending on the circumstances, businesses may need to watch for:
- Similar spellings
- Similar sounding names
- Similar logos or visual elements
- Abbreviations
- Translations
- Transliterations
- Different versions of a distinctive word
- Applications in related goods or service classes
Â
For example, a company operating under the brand NORTHBRIDGE should not necessarily monitor only applications containing the exact word NORTHBRIDGE.
A new application using a similar word, sound, spelling or dominant brand element may also deserve investigation.
When a potentially conflicting application is discovered, the business should promptly determine:
- When the application was published.
- When the opposition period expires.
- What goods and services the application covers.
- What earlier rights the business owns.
- How similar the respective marks are.
- Whether customers or markets overlap.
- What evidence is available.
- Whether opposition is commercially worthwhile.
Â
Speed is important because the opposition period continues to run while the business investigates the application or communicates with the applicant.
What Is the Deadline for Opposing a Trade Mark Application?
The normal period for opposing a Singapore trade mark application is two months from the date of publication in the Trade Marks Journal.
The publication date should therefore be checked immediately.
The available time may be needed to:
- Review the trade mark application.
- Analyse the relevant goods and services.
- Examine earlier registrations.
- Establish the history of brand use.
- Investigate the applicant.
- Identify the appropriate legal grounds.
- Gather supporting evidence.
- Consider settlement options.
- Prepare the statement of grounds.
Â
Waiting until the final few days can make it difficult to prepare a well supported opposition.
Can the Opposition Deadline Be Extended?
IPOS provides a procedure for requesting an extension of time to file a notice of opposition.
The relevant request may be made using Form HC3.
An extension request generally needs to be made within the existing opposition period. The required documents should also be served on the applicant and any other person who may be affected where required by the applicable procedure.
Importantly, requesting an extension should not be treated as a guarantee that additional time will be granted.
Businesses should also avoid assuming that negotiations with the applicant automatically suspend the opposition deadline.
For example, the parties may have begun discussing a coexistence arrangement, name change or limitation of goods and services. Unless the applicable procedural requirements have been satisfied, those discussions do not necessarily prevent the opposition period from expiring.
Where the deadline is approaching, the procedural position should be protected even if negotiations are continuing.
Common Grounds for Opposing a Trade Mark Application
The appropriate grounds depend on the facts of the dispute.
Singapore’s Trade Marks Act contains both absolute and relative grounds that may be relevant to an opposition.
1. Identical or Similar Earlier Trade Marks
One of the most common grounds involves an earlier registered or pending trade mark.
Relevant issues may include:
- Whether the marks are identical or similar.
- Whether the goods or services are identical or similar.
- Whether there is a likelihood of confusion where required.
- Which elements of the marks are distinctive.
- How consumers are likely to perceive the respective marks.
- Whether the earlier mark has an established reputation.
An opposition should therefore not be based solely on the argument that two logos “look similar”.
Trade mark similarity may involve visual, aural and conceptual considerations, together with the goods, services and relevant consumers.
2. Lack of Distinctiveness
A trade mark should be capable of distinguishing one trader’s goods or services from those of another.
A proposed mark may be challenged if consumers are unlikely to understand it as identifying a particular commercial source.
Ordinary promotional expressions or highly generic wording may therefore face difficulties depending on the goods or services involved.
3. Descriptive or Customary Wording
A trade mark may also face opposition where it merely describes characteristics of the relevant goods or services.
This could involve wording describing matters such as:
- Quality
- Quantity
- Intended purpose
- Characteristics
- Value
- Geographic origin
- Type of product or service
Words that are customary within a particular industry may also be difficult to monopolise as trade marks.
Whether wording is descriptive must be assessed in relation to the particular goods and services claimed.
4. Earlier Unregistered Rights and Passing Off
A business does not necessarily need a registered trade mark before it can challenge another application.
In appropriate circumstances, earlier unregistered rights may support an opposition through the law of passing off.
This can be particularly relevant where a business has traded under a particular name for many years but never registered the brand.
Such an opposition may require evidence establishing matters such as:
- Existing goodwill in Singapore.
- Use of the name or sign before the applicant’s relevant date.
- Customer recognition.
- The nature and extent of the business.
- Circumstances capable of creating a misrepresentation.
- Potential damage to the earlier business.
Because passing off depends heavily on evidence of actual market activity, these cases may require more extensive documentation than an opposition based on an earlier registered trade mark.
5. Bad Faith
An application may also be challenged where it was allegedly made in bad faith.
This can arise in situations involving parties that previously had a commercial relationship.
Examples that may warrant investigation include applications filed by a:
- Former distributor
- Agent
- Employee
- Business partner
- Manufacturer
- Licensee
- Joint venture participant
For example, a local distributor may have learned about an overseas brand through its relationship with the brand owner and subsequently filed the brand as its own Singapore trade mark.
However, bad faith is a serious allegation.
The fact that an applicant knew another business existed does not automatically establish bad faith. The commercial relationship, knowledge of the brand, chronology of events and circumstances surrounding the filing must all be assessed.
What Evidence Should Be Collected Before Filing an Opposition?
Evidence should be collected according to the legal grounds relied upon.
Potentially relevant material may include:
- Trade mark registration certificates.
- Earlier trade mark applications.
- Records showing when the brand was first used.
- Sales invoices.
- Purchase orders.
- Product catalogues.
- Packaging.
- Advertising material.
- Marketing expenditure records.
- Website records.
- Social media posts.
- Media coverage.
- Customer records.
- Distribution records.
- Market share information.
- Evidence of consumer recognition.
- Complaints or enquiries showing actual confusion.
- Emails and correspondence between the parties.
- Distribution or agency agreements.
- Licensing arrangements.
- Documents demonstrating the applicant’s prior knowledge of the brand.
- Earlier overseas trade mark registrations.
Â
It is not always helpful to submit every document the business can locate.
A stronger strategy is to identify precisely what needs to be proved and then gather evidence that supports those points.
For example, if the opposition relies on passing off, records showing years of Singapore sales and customer recognition may be particularly important.
If the opposition relies on bad faith, emails and documents explaining the previous relationship between the applicant and opponent may carry greater significance.
How to File Form TM11
A trade mark opposition is generally commenced by filing Form TM11 together with a statement of grounds.
As at August 2026, the official IPOS fee is:
S$420 × the number of classes being opposed
For example, if an application covers three classes but the opponent challenges only two of them, the filing fee would generally be calculated according to the two opposed classes.
The same Form TM11 and statement of grounds must also be served on the trade mark applicant in accordance with the applicable procedure.
The opposition documents should correctly identify:
- The application being opposed.
- The opponent.
- The classes being challenged.
- The statutory grounds relied upon.
- The material facts supporting the opposition.
Why the Statement of Grounds Matters
The statement of grounds is a central document in the opposition.
It should do more than state that the proposed trade mark is “too similar” to the opponent’s brand.
The opponent should clearly identify:
- Which legal provisions are being relied upon.
- What earlier rights exist.
- Which facts support those rights.
- Why the proposed registration should be refused.
Poorly drafted or excessively broad grounds may create problems later.
For example, if evidence is submitted on an issue that was never properly pleaded, questions may arise as to whether that material can support the opponent’s case.
Similarly, alleging numerous grounds without a proper factual basis can increase the complexity and cost of the proceedings without improving the chances of success.
A focused opposition based on well supported grounds may be more effective.
What Must the Trade Mark Applicant Do Next?
An applicant who intends to defend the application generally has two months after receiving the notice of opposition to file a counter statement using Form HC6.
As at August 2026, the official IPOS filing fee for Form HC6 is S$360 for each opposed class.
The counter statement allows the applicant to respond to the opponent’s case and identify which allegations are admitted or disputed.
A copy must also be served on the opponent in accordance with the applicable procedure.
Failure to respond within the required timeframe can have serious consequences.
Where the applicant does not properly file the counter statement, the application may be treated as withdrawn in relation to the opposed classes.
An applicant that receives a trade mark opposition should therefore take the notice seriously even if it considers the opponent’s case to be weak.
What Happens After the Counter Statement?
An opposition does not normally proceed immediately to a final hearing.
After the counter statement is filed, the parties may be given an opportunity to consider whether the dispute can be resolved through negotiation, mediation or another form of dispute resolution.
If the matter is not settled, the proceedings generally move into the evidence stage.
A simplified process is:
Trade mark application published
↓
Form TM11 and statement of grounds filed
↓
Applicant files Form HC6 counter statement
↓
Parties consider settlement or mediation
↓
Opponent files evidence
↓
Applicant files evidence
↓
Opponent may file reply evidence where permitted
↓
Pre hearing review
↓
Written submissions and authorities
↓
Hearing before IPOS
↓
Decision and possible costs order
The exact procedure can vary depending on the case and directions issued by IPOS.
Evidence in Trade Mark Opposition Proceedings
If the dispute continues, IPOS may give directions for the filing of evidence.
The opponent will generally present evidence first.
This may include statutory declarations together with supporting documents such as:
- Registration records.
- Sales documents.
- Advertising material.
- Contracts.
- Market evidence.
- Correspondence.
- Evidence of confusion.
- Evidence concerning the history of the relationship between the parties.
Â
The applicant then has an opportunity to provide its own evidence.
Depending on the case, the opponent may subsequently be permitted to file evidence in reply.
Evidence deadlines should be taken seriously.
Failure by the opponent to comply with applicable evidential requirements can jeopardise the opposition.
Likewise, failure by the applicant to comply with the required procedure can jeopardise the trade mark application.
Parties should therefore plan their evidence early rather than assuming that additional documents can always be submitted shortly before the hearing.
Can a Trade Mark Opposition Be Settled?
Yes.
A formal opposition does not necessarily have to end with a contested hearing.
Many trade mark disputes involve commercial issues that may be resolved through negotiation.
Possible settlement arrangements include:
- Withdrawal of the trade mark application.
- Withdrawal of the opposition.
- Limiting particular goods or services.
- Changing part of the brand.
- Modifying a logo.
- Entering into a coexistence agreement.
- Restricting use to particular markets.
- Dividing sales channels.
- Agreeing geographic limitations.
- Providing undertakings concerning future use.
- Licensing the trade mark.
- Assigning or transferring certain rights.
Â
A settlement should address future commercial developments, not only the parties’ current activities.
For example, two businesses may presently operate in different industries but have plans to expand into overlapping markets.
A coexistence agreement that does not anticipate future products, online sales, regional expansion or related companies can create further disputes later.
Mediation in Singapore Trade Mark Opposition Proceedings
Mediation can be particularly useful in intellectual property disputes because it allows the parties to consider broader commercial solutions.
A court or tribunal decision generally determines who succeeds on the legal issues placed before it.
Mediation can potentially produce more flexible outcomes, such as:
- Changes to packaging.
- Different market positioning.
- Division of product categories.
- Different geographic markets.
- Licensing arrangements.
- Transitional periods for changing branding.
- Agreements covering several countries.
- Transfer of domain names or social media accounts.
- Settlement of related commercial disputes.
Â
IPOS provides mechanisms that allow proceedings to be suspended in appropriate circumstances while mediation or settlement is pursued.
However, parties should ensure that the procedural status of the opposition is properly protected during negotiations.
What Happens at the Opposition Hearing?
Where the opposition cannot be resolved, it may eventually proceed to a hearing before IPOS.
Before the hearing, the parties may participate in a pre hearing review where procedural matters and the possibility of resolving or narrowing the dispute can be considered.
The parties will also generally prepare:
- Written submissions.
- Bundles of legal authorities.
- Evidence relied upon.
- Submissions concerning costs.
Â
A party wishing to appear at the hearing may be required to file Form HC1.
As at August 2026, the IPOS hearing fee for trade mark proceedings is generally S$1,000 for the first class and S$800 for each subsequent class for each trade mark number.
At the hearing, the parties present their legal arguments based on the pleaded grounds and evidence.
IPOS will subsequently issue its decision.
Depending on the outcome, the application may:
- Proceed to registration.
- Proceed only for some goods or services.
- Be refused for the opposed classes.
- Be affected by other directions arising from the decision.
Â
The Registrar may also make an order relating to costs.
Can an IPOS Opposition Decision Be Appealed?
A party dissatisfied with an opposition decision may have a right to appeal in accordance with the applicable legislation and procedural rules.
The appeal period is relatively short.
A party considering an appeal should therefore review the decision promptly rather than waiting until the deadline approaches.
An appeal should also be assessed commercially.
Relevant considerations may include:
- The importance of the brand.
- The strength of the legal arguments.
- The evidence already before IPOS.
- The cost of continuing the dispute.
- The impact of the decision on the business.
- Whether settlement remains possible.
What If the Trade Mark Has Already Been Registered?
If the mark has already proceeded to registration, the ordinary opposition procedure is generally no longer available.
A party may instead need to consider invalidation or revocation.
IPOS currently identifies Form TM28 for applications to invalidate or revoke a registered trade mark.
As at August 2026, the official filing fee is S$420 for each class for which revocation or invalidation is sought.
The correct procedure depends on the reason for challenging the registration.
Invalidation
Invalidation may be relevant where the argument is that the trade mark should not have been registered in the first place.
Potential issues may include:
- Earlier rights.
- Lack of distinctiveness.
- Descriptiveness.
- Bad faith.
- Other statutory grounds affecting validity.
Revocation
Revocation generally concerns circumstances affecting an existing registration.
One important example is prolonged non use where the statutory requirements for revocation are satisfied.
The grounds, evidence and timing differ from an opposition.
Businesses should therefore determine the registration status before choosing an enforcement strategy.
What If the Applicant Is Already Using the Trade Mark?
Opposition proceedings concern whether the application should be registered.
They do not necessarily resolve every issue concerning the applicant’s commercial use of the mark.
If the applicant is already using the disputed branding in Singapore, the earlier rights holder may also need to consider whether there are separate grounds for:
- Trade mark infringement.
- Passing off.
- Copyright infringement.
- Breach of contract.
- Breach of a distribution agreement.
- Misrepresentation.
- Other intellectual property or commercial claims.
Â
For example, opposing an application may prevent the applicant from obtaining registration but may not automatically stop existing marketplace use.
A broader enforcement assessment may therefore be necessary.

Obtain an urgent assessment and consider whether Form TM11 or an extension request should be filed.
The trade mark has already been registered
Consider invalidation or revocation instead of ordinary opposition.
The applicant is already using the disputed trade mark
Consider whether infringement, passing off or another commercial claim should also be investigated.
The parties may be able to coexist
Consider negotiation or mediation while ensuring that all procedural deadlines remain protected.
Common Mistakes When Opposing a Trade Mark Application
Waiting Too Long
A two month opposition period can pass quickly.
Investigating the applicant, obtaining historical documents and preparing the statement of grounds all take time.
Businesses should begin assessing the application as soon as it is discovered.
Â
Assuming Similar Names Automatically Mean Opposition Will Succeed
Trade mark law involves more than comparing two words side by side.
The legal analysis may involve:
- The overall similarity of the marks.
- Distinctive and dominant elements.
- Goods and services.
- Customer groups.
- Market circumstances.
- Earlier rights.
- The statutory ground relied upon.
A commercially irritating similarity does not automatically amount to a legally successful opposition.
Â
Filing Too Many Grounds
It can be tempting to include every possible legal ground.
However, an opposition should be built around grounds supported by the evidence and facts.
Weak additional grounds may unnecessarily complicate the case.
Â
Failing to Preserve Evidence
Online evidence can disappear quickly.
Websites may be redesigned, advertisements removed and social media posts deleted.
Businesses should preserve relevant material once a potentially conflicting application is identified.
Â
Ignoring Unregistered Rights
Not having a registered trade mark does not always mean that nothing can be done.
A business with established goodwill may potentially rely on passing off or other earlier rights.
The evidential burden may, however, be more substantial.
Â
Assuming Negotiations Stop the Clock
Settlement discussions should not be assumed to suspend procedural deadlines automatically.
The parties should protect their procedural position while negotiations continue.
Â
Treating Litigation as the Only Successful Outcome
The objective should usually be to protect the business, not simply to win a legal proceeding.
A commercially useful settlement may sometimes achieve a better result through:
- Limiting goods or services.
- Changing a logo.
- Restricting particular markets.
- Agreeing separate sales channels.
- Licensing.
- Controlled coexistence.
Â
The appropriate solution depends on the long term interests of the brand.
Frequently Asked Questions About IPOS Trade Mark Objections
A person may oppose a published trade mark application where there are proper grounds under Singapore trade mark law.
The success of the opposition will depend on the statutory grounds relied upon, the relevant facts and the available evidence.
The normal opposition period is two months from the publication date of the accepted application in the Trade Marks Journal.
Because the period is relatively short, a potentially conflicting application should be assessed promptly.
IPOS provides Form HC3 for requesting an extension of time in relation to the filing of a notice of opposition.
The request generally needs to be made before the original opposition period expires.
An extension should not be assumed to be automatic.
As at August 2026, the official IPOS filing fee for Form TM11 is S$420 for each class opposed.
Additional costs may arise from legal representation, evidence preparation, mediation, hearings and other stages of the proceedings.
An applicant wishing to defend the trade mark application generally has two months after receiving the opposition to file its counter statement using Form HC6.
Failure to file the required counter statement may result in the application being treated as withdrawn for the opposed classes.
Yes.
The parties may resolve the dispute through negotiation or mediation.
Possible settlement terms include limiting goods and services, modifying branding, entering into a coexistence agreement, licensing the mark or withdrawing the application or opposition.
Potentially.
Earlier unregistered rights may be relevant, particularly where the business has established goodwill capable of supporting a passing off claim.
Evidence of earlier use, customer recognition and market activity may therefore be important.
Ordinary opposition is generally no longer available.
Depending on the circumstances, invalidation or revocation may need to be considered.
If the registered owner is also using the mark commercially, infringement, passing off or other claims may also require assessment.
Speak to an Intellectual Property Lawyer in Singapore
Opposing a trade mark application in Singapore requires both speed and a clear legal strategy.
Once IPOS accepts an application and publishes it in the Trade Marks Journal, there is generally only a two month period in which a third party may commence opposition proceedings.
The opponent must identify the appropriate legal grounds, prepare a properly particularised statement of grounds, file Form TM11 and comply with the applicable procedural requirements.
If the opposition continues, the dispute may involve a counter statement, evidence, settlement discussions, mediation, written submissions and ultimately a hearing before IPOS.
However, not every conflicting trade mark application needs to result in a fully contested proceeding.
Depending on the circumstances, a commercially appropriate solution may involve limiting the application, changing certain branding elements, negotiating coexistence or resolving the dispute through mediation.
The critical point is to assess the application before the opposition period expires.
Once registration has taken place, different procedures and legal considerations may apply.
