To check if something is trademarked, start with the official trademark database for each country or region where you plan to use the name, logo or slogan.
Search the exact mark first, then try spelling, phonetic and visual variations. For every relevant result, review its status, owner, filing date, territory and the goods or services it covers.
A free database search can identify obvious problems. However, finding no exact match does not automatically mean that a mark is available to use or register.
Why Should You Check If Something Is Trademarked?
A trademark search can help you identify legal and commercial risks before you invest in a new brand:
- Reduce infringement risk. An earlier identical or similar mark may give its owner grounds to challenge your use.
- Avoid an expensive rebrand. Discovering a conflict after launch may mean changing packaging, signage, domains and advertising.
- Prepare a stronger application. Finding potential obstacles early gives you time to modify the mark or filing strategy.
- Reduce consumer confusion. A clearly differentiated brand is less likely to be mistaken for another business.
Trademark rights are territorial. A name may be available in one country but conflict with an earlier application or registration somewhere else.
How Can You Check If a Name Is Trademarked?
1. Search National Trademark Offices
Most trademark offices provide a free database containing registered marks and pending applications.
Common official resources include:
These are examples, not a complete list. Check the official intellectual property office in every country where the mark will be used or registered.
When searching:
- Start with the exact name.
- Try separate words, partial words, plurals and alternative spellings.
- Search words that sound similar when spoken.
- Consider translations or transliterations where relevant.
- Review pending applications as well as registered marks.
- Record the mark owner, status, dates and territory.
- Read the actual list of goods and services, not just the class number.
A pending application may be relevant even though it has not yet reached registration.
2. Check Local and Common-Law Uses
An official trademark database may not reveal every right that could affect your proposed mark.
Depending on the country, earlier rights may arise from use, trade names, company names, well-known marks or other legal protections. To identify possible unregistered uses, check:
- Company and state or provincial registries: These may reveal businesses using the same or a similar name.
- Trade directories and marketplaces: Search for use within the same industry or product category.
- Search engines: Look for businesses already trading under the name.
- Domains and social media: Review how the name is being used online.
A registered company name, available domain or unused social media handle does not prove that a trademark is available. Company registration, domain registration and trademark rights are separate matters.
The importance of unregistered use varies by jurisdiction. Common-law trademark rights are particularly relevant in countries such as the United States, but other countries may recognize different forms of prior use or earlier rights.
3. Check International and Logo Databases
If the mark will be used in several countries, international tools can provide a useful first overview.
WIPO Global Brand Database
The WIPO Global Brand Database includes international trademarks registered through the Madrid System and collections from participating national and regional offices.
You can search by:
- Trademark name or keywords.
- Owner or registration number.
- Goods and services.
- Image similarity.
- Combinations of different search criteria.
The database does not necessarily include every relevant record worldwide. Check the national or regional register for each important market as well.
TMview and TMclass
TMview provides access to applications and registrations from the EUIPO, EU national offices and other participating trademark offices.
TMclass serves a different purpose. It helps identify acceptable terms and Nice classes for goods and services. TMclass is not a trademark availability database.
How to Check If a Logo Is Trademarked
A text search may not be enough when the proposed mark includes a logo or other graphic elements.
For a logo search:
- Search any words appearing in the logo.
- Use image-search functionality where available.
- Review figurative and combined marks.
- Search relevant Vienna Classification codes.
- Consider the logo's overall appearance, not just individual shapes.
The WIPO database supports image-similarity searches, while some national offices also offer image searching or design search codes.
An industrial design database is not a substitute for searching figurative trademarks. Industrial designs and trademarks protect different subject matter.
4. Consider a Professional Trademark Search
Free searches are useful for detecting obvious matches, but similar marks are often harder to identify and assess.
A professional clearance search may help you:
- Identify identical and similar names.
- Find phonetic, visual and conceptual similarities.
- Review related goods and services, including those in different classes.
- Evaluate pending applications and active registrations.
- Check the territories relevant to your business.
- Understand whether the results may create a likelihood of confusion.
A professional search may be appropriate when:
- You are investing significantly in packaging, advertising or a product launch.
- You intend to operate in several countries.
- The name contains common, descriptive or highly competitive wording.
- Your preliminary search reveals similar marks.
- The mark includes important visual elements.
- Rebranding after launch would be particularly costly.
The International Trademark Search Service can help you review identical and similar marks before filing.
How Should You Interpret Trademark Search Results?
The presence of an identical or similar result does not automatically determine whether you can use or register your mark.
Review at least these factors:
- Territory: Trademark rights normally apply only in particular countries or regions.
- Similarity: Marks may be visually, phonetically or conceptually similar without being identical.
- Goods and services: The comparison depends on what each mark covers and whether the activities are related.
- Status: A pending application or active registration may be more relevant than an expired or cancelled record.
- Dates: Earlier filing, priority or use dates can affect which party has prior rights.
- Likelihood of confusion: The central question is often whether people could believe the goods or services come from the same or connected businesses.
Two identical names may sometimes coexist when they cover sufficiently unrelated activities. Conversely, differently spelled names may conflict when they sound alike and cover related goods or services.
Trademark classes help organize searches, but they are not automatic boundaries. Related products or services can sometimes fall in different classes.
Does No Search Result Mean the Mark Is Available?
No. A search showing no exact matches is a useful first result, but it does not prove that the mark is available or registrable.
A search may miss:
- Alternative spellings or phonetic similarities.
- Logos with similar visual elements.
- Relevant results in related goods or services.
- Earlier unregistered use.
- Records in another national or regional database.
- Marks that are legally relevant for reasons other than similarity.
It is also possible for a mark to face objections because it is descriptive, generic, misleading or otherwise lacks distinctiveness, even when no similar registration appears.
How to Check If Something Is Trademarked: Quick Checklist
- Identify every country or region where you plan to use the mark.
- Search the exact name in each relevant official database.
- Search spelling, phonetic and visual variations.
- Review the status, dates, owner, territory and goods or services.
- Check business directories, domains, marketplaces and unregistered use.
- Request professional analysis if the results are unclear or the brand represents a significant investment.
If you find an earlier registration, read what to do if your business name is already trademarked before assuming that you must abandon the name.
