There's No Single Global Register — But There Are Aggregators
Trademarks are territorial. Each country maintains its own register, and there is no one worldwide database that owns them all. The good news is that several free aggregator tools pull data from dozens of national offices into a single search, so you can screen a name across most major markets in minutes without visiting each office one by one. It's the international counterpart to a domestic free trademark search.
The Free Tools That Cover the World
- WIPO Global Brand Database — run by the World Intellectual Property Organization, it searches tens of millions of records across many national and international sources, including international (Madrid) marks. Supports text and image search. Free.
- TMview — operated by the EUIPO, TMview aggregates trademark data from 75+ participating offices worldwide, including the USPTO, EUIPO, UKIPO, and many national registers. The widest single free search available. Free.
- Madrid Monitor — WIPO's tool for tracking the status of Madrid Protocol international registrations specifically — useful once you've filed internationally.
- National registers — for any market that really matters, finish with the country's own office (USPTO, IPONZ, CIPC, CNIPA, and so on), since aggregators can lag slightly behind the source.
Start broad with TMview or the WIPO Global Brand Database to catch obvious global conflicts, then drill into the specific national registers for the countries you actually plan to enter.
How to Run the Search
- Search the exact mark across TMview and the WIPO Global Brand Database.
- Search variations — phonetic equivalents, alternate spellings, and translations into the local languages of your target markets.
- Filter by class. A conflict only matters if it covers similar goods or services, so narrow to your Nice class(es).
- Note status and territory for each hit — a live registration in a market you're entering is a blocker; a dead one in a market you'll never touch is not.
- Confirm the priority markets directly on the national register before committing.
Why It Matters Before You Expand
A name that's clear in the United States can be already registered — or deliberately squatted — in a market you're about to enter. In first-to-file countries, whoever registers first generally wins, regardless of who used the name first elsewhere. Discovering a conflict before you ship products or sign distributors saves a forced rebrand abroad, which is far more expensive than the search. A worldwide screening search is the cheapest insurance for any international move.
Aggregator databases are a screening tool, not legal clearance. They can miss unregistered (common law) rights, very recent filings, and local-language variants. For markets that matter, back the search with a professional clearance opinion from local counsel.
Frequently Asked Questions
Is there a single worldwide trademark database?
No single register owns every mark, but free aggregators come close. WIPO's Global Brand Database and the EUIPO's TMview each search dozens of national offices at once, covering most major markets.
How do I search trademarks internationally for free?
Use TMview (75+ offices) and the WIPO Global Brand Database to screen your name across many countries, search variations and translations, filter by class, then confirm priority markets on each national register.
What is Madrid Monitor?
It's WIPO's free tool for tracking the status of international registrations filed through the Madrid Protocol. It's most useful after you've filed internationally, to follow each designated country's progress.
Is a worldwide search enough to clear a name globally?
No. Aggregators are a screening tool that can miss common law rights, recent filings, and local-language variants. For markets that matter, get a professional clearance opinion from local counsel.
