UK Trademark Search: How to Use the UKIPO Database Before Filing
A thorough trademark search is the most important step you can take before filing a UK trademark application. The UKIPO examiner will assess your mark against absolute grounds (descriptiveness, etc.), but will not proactively search for conflicting earlier marks. That responsibility falls entirely on you.
This guide explains how to conduct an effective UK trademark search using the UKIPO database and other resources.

Why Search Before Filing?
Filing without searching is like driving blindfolded:
- Opposition risk — a third party with an earlier similar mark can oppose your application during the 2-month publication period
- Infringement risk — even if your mark registers, using it may infringe an earlier right
- Wasted costs — filing fees (GBP 170+) are non-refundable
- Time lost — the entire process takes 4+ months; starting over doubles the delay
The UKIPO does not refuse applications on relative grounds (similarity to existing marks) at the examination stage. Instead, owners of earlier marks can file oppositions during the publication period.
UKIPO Online Trademark Search
The UKIPO provides a free search tool at gov.uk/search-for-trademark.
Search by Trademark Number
If you know the specific trademark number (e.g., UK00003123456), you can look it up directly to see:
- Registration status
- Owner details
- Goods/services covered
- Filing and registration dates
- Any pending actions
Search by Keyword/Brand Name
The most common search method. Enter your proposed brand name to find similar marks.
Tips for effective keyword searches:
- Search for exact matches first
- Then try variations (plural forms, misspellings, phonetic equivalents)
- Remove spaces and special characters
- Search for each word individually if your mark is multi-word
Search by Owner
Useful for competitive intelligence — see all trademarks registered by a specific company or individual.
Search by Classification (Nice Classes)
Filter results by the Nice Classification classes relevant to your goods/services. A mark in Class 25 (clothing) may not conflict with an identical mark in Class 9 (electronics).
Beyond the UKIPO Database
The UKIPO database only covers registered UK trademarks and pending applications. A comprehensive search should also check:
TMview
TMview is a free tool from the European Union Intellectual Property Network that searches across 70+ trademark offices globally, including the UKIPO.
Advantages:
- Cross-jurisdictional search in one place
- Includes EU trademarks that may have earlier priority
- Visual search capabilities for figurative marks
Common Law Rights (Unregistered Marks)
In the UK, unregistered trademarks can acquire protection through the tort of passing off. A business that has built goodwill in an unregistered mark can:
- Oppose your trademark application
- Sue for passing off even if your mark is registered
To check for unregistered rights:
- Search Companies House for similar business names
- Search domain name registries
- Check social media platforms and online marketplaces
- Review industry directories and trade publications
International Registrations
Search WIPO's Global Brand Database for Madrid Protocol registrations designating the UK.
Understanding Search Results
Identical Marks
An identical mark in the same or similar class is the clearest conflict. This almost certainly means your application will face opposition.
Similar Marks
Assessing similarity involves three factors:
- Visual similarity — how the marks look when written or displayed
- Phonetic similarity — how the marks sound when spoken
- Conceptual similarity — what the marks mean or suggest
The UKIPO and UK courts apply the "global appreciation" test — considering the overall impression of the marks rather than analysing individual elements in isolation.
Goods/Services Overlap
Even a similar mark may not conflict if the goods/services are sufficiently different. However, well-known marks enjoy broader protection that can extend beyond their registered classes.
Phonetic and Visual Similarity Analysis
Phonetic conflicts are commonly overlooked:
| Your Mark | Potential Conflict | Why |
|---|---|---|
| KLEEN | CLEAN | Phonetically identical |
| PHAST | FAST | Phonetically identical |
| BYKE | BIKE | Phonetically identical |
| GREYSTONE | GRAYSTONE | Visually and phonetically similar |
The UKIPO and UK Appointed Persons have consistently held that phonetic similarity alone can be sufficient to refuse or invalidate a mark.
Classification Strategy
The UK uses the Nice Classification system (same as the EUIPO and most other jurisdictions). When searching, consider:
- Your primary class — the core goods/services
- Related classes — classes where consumers might expect your brand to operate
- Defensive classes — classes where confusion could damage your reputation
For example, a coffee brand (Class 30) should also search Class 43 (café services), Class 35 (retail services), and Class 21 (coffee-related merchandise).
The GTC advantage: Our new trademark filing service includes a comprehensive multi-class search and classification strategy, ensuring no conflicting marks are missed.
Search Limitations
What the UKIPO Database Won't Tell You
- Common law rights — unregistered marks with goodwill
- Pending applications — newly filed marks may not appear immediately
- International registrations — Madrid Protocol designations may take time to appear
- Degree of risk — the database shows what exists, not how likely a conflict is to result in opposition
When to Get Professional Help
Consider a professional search if:
- Your mark is similar (but not identical) to existing marks
- You're filing in multiple classes
- You're entering a crowded market (e.g., fashion, tech, food and beverage)
- Your brand name is a common English word or phrase
- You're investing significantly in brand development
