Registering a company name with ACRA does not register that name as a trade mark in Singapore. A trade mark identifies the commercial origin of goods or services and is registered through the Intellectual Property Office of Singapore (IPOS). The current online application fee is S$280 per class when all goods/service descriptions use IPOS pre-approved wording, or S$410 per class when that condition is not met. A registered trade mark lasts ten years from its filing date and can be renewed.
If you searched for Singapore trademark registration, IPOS TM4 fees, trademark search Singapore, trade mark classes, registered trademark symbol, IPOS Digital Hub or how to protect a brand name, start by separating a business identity from intellectual-property protection. A UEN is a government entity identifier; a web domain is an internet address; a copyright concerns qualifying original expression; and a registered trade mark protects the distinctive sign within its approved goods or services. One does not automatically create the others.
Quick action: Search existing marks at the official IPOS Digital Hub, assess whether your proposed sign is distinctive, select the correct goods/service classes and descriptions, submit Form TM4, answer examination objections, follow the publication and two-month opposition period, then verify registered status. Use the ® symbol only once the mark is registered. This Singapore Vocabulary guide explains the terms and decisions without promising every application will succeed.

What can be registered as a trade mark?
IPOS says a trade mark must be capable of graphic representation and of distinguishing a trader’s goods or services from another’s. A coined brand word or distinctive logo may have greater potential than ordinary descriptive phrases such as ‘best cheap tuition’ for tuition services, subject to actual examination. Using a design agency or owning a logo file does not mean the resulting mark meets legal distinctiveness requirements.
Registration can also be refused because the proposed sign is identical or confusingly similar to an earlier protected mark for related goods or services. Similarity is not limited to two exact strings: appearance, sound, concepts and commercial relationship can matter. An ordinary Google search is not a substitute for the actual IPOS register and appropriate professional advice where risk is significant.
Why ACRA, UEN, domain and trade mark are different
| You hold | What you have | What you still do not necessarily own |
|---|---|---|
| ACRA business name | A registered name for operating an entity | Exclusive trade mark rights in that phrase |
| UEN | A unique official entity identifier | Brand ownership or trade mark registration |
| .com or .sg domain | An internet address | Legal right to prevent all similar brands |
| Copyright in original logo artwork | Potential protection for artistic expression | Trademark protection for the commercial sign |
| IPOS registered trade mark | Statutory rights for approved sign/classes | Universal worldwide monopoly over any use |
Consider a fictional Singapore startup called Harbour Lantern Academy. It registers an ACRA entity and buys a matching domain. A different earlier trader could still have an IPOS trade mark that conflicts with the proposed brand for certain educational services. Before printing signage, choosing uniforms or building substantial search traffic around a name, verify the rights landscape. Rebranding later can be expensive.
How to search for conflicting marks
- Start at IPOS Digital Hub and use the Similar Mark Search function.
- Search the proposed exact brand word and plausible alternative spellings.
- Examine marks that look or sound similar, especially for related goods or services.
- Read class numbers and the actual goods/services descriptions; a matching word in an unrelated market may present a different question.
- Check each relevant mark’s status, proprietor and filing or registration particulars.
- Consider the risk of unregistered goodwill or other existing rights even when no identical registered mark appears.
- When a name is business-critical or confusingly close, obtain professional advice rather than assuming an automated search grants clearance.
Why classes matter more than a marketing category
The Nice Classification divides goods and services into 45 classes. IPOS explains that the scope of a registered mark depends on the goods/service specification chosen, not merely the name of the business. Class 35 can include certain advertising, retail or business services, while Class 41 includes many education or training services. A physical learning product may require consideration of another class. Always select actual product/service descriptions from the applicable classification rather than assume any company in education needs only Class 41.
Example: a business offers both training and retail
A fictional brand provides paid workshops and operates an online store for physical products. It may require different goods and service classes. If two classes use only IPOS pre-approved descriptions, the minimum normal online TM4 filing fee at S$280 per class would be S$560. If one class uses a non-pre-approved description, the application charges may differ by class. The example does not determine which actual classes the business should file or guarantee a successful mark.
Why S$280 and S$410 are both correct
IPOS’s current TM4 schedule lists S$280 per class when every specification entry in that class comes from its pre-approved Classification Database, and S$410 per class when this is not true. That is a filing fee, not an insurance premium or payment for guaranteed registration. IPOS encourages using approved descriptions because they can reduce objections about classification and help avoid unnecessary delays.
An optional acceleration request under SG Trade Marks Fast may involve additional charges: currently S$200 per class for the fully approved-description category or S$250 per class for other descriptions, subject to the service’s rules. Faster examination is not a promise that the mark will be accepted or protected. The correct description of a product still matters more than optimising a filing fee at all costs.
Application steps from draft to final registration
| Step | IPOS status/action | What it means |
|---|---|---|
| 1. Search | Similar Mark Search | Preliminary risk check |
| 2. Prepare | Class and goods/services specification | Defines intended protection |
| 3. File | Form TM4 with representation, applicant and fee | Creates formal application |
| 4. Examination | IPOS checks form and registrability | May result in objection |
| 5. Publication | Accepted mark appears in Trade Marks Journal | Two-month opposition opportunity |
| 6. Opposition if any | Interested party contests | Registration may be delayed or refused |
| 7. Registration | Certificate and Registered status issued | Use ® for registered mark |
| 8. Renewal | Form TM19 before expiry | Extend protection for another ten years |
A brand should not announce ‘our trade mark is registered’ merely because an IPOS payment acknowledgement arrived. Filing, examination, publication, opposition and registration are separate milestones. When IPOS has issued an office action, the applicant must meet the stated requirements and timing. Ignoring correspondence can cause avoidable loss of the application.
The two-month opposition window
After an application passes examination, IPOS publishes the accepted mark for public inspection in the Trade Marks Journal. Interested parties ordinarily have two months to oppose. A filed opposition can suspend the application pending the applicable proceedings. No opposition normally allows registration to proceed, subject to any other outstanding issues.
This is why commercial plans should allow room for uncertainty between filing and registration. A new restaurant or tuition business might use the branding commercially while waiting, but it should not misuse the registered symbol or state protection is final until IPOS confirms registration.
® and ™: why a tiny symbol matters
IPOS distinguishes the informal ™ symbol, which can indicate that a trader claims a name or design as a mark, from ®, which signifies registered status. In Singapore, ® should only be used after the trade mark register actually shows the status as Registered. Using ® on a merely applied-for mark can mislead customers or raise legal issues. This is a practical vocabulary rule that businesses can check before printing packaging.
Registration lasts ten years, then what?
IPOS protection ordinarily lasts ten years from the filing date, with the possibility of repeated ten-year renewals. Current Form TM19 on-time renewal costs S$480 per class, while a late renewal is S$700 per class and qualifying restoration costs S$770 per class under the listed schedule. These processes have conditions and deadlines. Keeping a calendar reminder prevents accidental lapse.
Suppose a fictional business registers a mark covering two classes. An on-time normal renewal at S$480 per class would cost S$960 in current fees, excluding any professional charges or intervening law changes. This is a general cost illustration, not a guarantee that future fees remain identical.
Trade mark, copyright, patent and registered design compared
| Right | Primary subject | How it works in simple terms |
|---|---|---|
| Trade mark | Signs identifying origin of goods or services | Registration with IPOS gives statutory brand protection in covered scope |
| Copyright | Original qualifying literary, artistic and other expression | Often arises automatically without trade mark registration |
| Patent | Qualifying invention | Requires application and examination for statutory patent protection |
| Registered design | Eligible product visual appearance | Separate formal registered right |
| Trade secret | Valuable confidential business information | Protected through confidentiality and lawful controls |
| Domain name | Internet addressing | Not an intellectual-property registration equivalent to trade mark |
A distinctive logo may involve both copyright in the creative design and trade mark protection for commercial branding if registered. These are related but different rights. A patent for a novel piece of equipment would not automatically protect the equipment’s marketing name. Choosing the correct legal mechanism requires knowing what exactly you want to protect.
Does a Singapore registration protect the brand worldwide?
Trade mark protection is territorial. Registration with IPOS gives protection under Singapore’s trade mark system for the covered mark and goods/services, not an automatic exclusive right in every market. Businesses expanding overseas may consider filing in individual jurisdictions or through appropriate Madrid Protocol international routes, with separate designations, fees and examination.
For example, an online shop shipping globally can have a Singapore trade mark but still encounter another business’s protected earlier mark in a country it enters. An international brand strategy should match actual intended markets; copying the Singapore certificate onto a global website does not create foreign registrations.
A practical brand-protection checklist
- Write down the exact brand sign — word, design or combination — you want to use.
- List current and realistic future goods and services sold under that sign.
- Search IPOS records for identical and confusingly similar earlier marks.
- Check the goods/service descriptions and relevant Nice classes.
- Use IPOS-approved descriptions when they accurately describe the business; do not distort activities to save a fee.
- Check that the intended applicant is the proper person or entity that should own rights.
- Submit Form TM4 and keep the filing receipt and deadline for answering objections.
- Monitor publication and any opposition, and use ® only after registered status.
- Calendar the ten-year renewal and preserve evidence of genuine commercial use.
Common Singapore trade mark misunderstandings
| Misleading claim | More accurate explanation |
|---|---|
| My ACRA name gives me complete trademark rights. | ACRA entity naming and IPOS trade mark registration are separate. |
| Owning .com.sg means nobody may use the brand. | A domain is not registered trade mark protection. |
| Every trade mark application costs just S$280 total. | Fees are per class; custom descriptions may be S$410 per class. |
| A business can register any common descriptive word. | Distinctiveness and statutory grounds affect registration. |
| A filed application lets me use ® immediately. | ® is for a registered mark. |
| One class protects all future products in every industry. | Protection depends on listed goods/service classes and descriptions. |
| The certificate lasts forever without any action. | Renewal is normally required every ten years. |
| A Singapore trade mark is automatically enforceable worldwide. | Protection is territorial; foreign registrations may be needed. |
| IPOS must register my brand if I pay faster examination fees. | Payment for acceleration does not decide legal registrability. |
