International (WIPO) trademark search
A global trademark search of the Madrid System register: 592,895 international registrations, searched by name in your classes or by logo. For each mark: who owns it, the countries it was designated in, and the ones that refused it. Free, no account.
Search international trademarks by logo
Upload the artwork and it is compared against 275,753 Madrid registrations with a logo image, and against the U.S. register, by image structure, by what the image depicts and by the wording inside it.
What an international trademark search tells you
There is no such thing as a world trademark. The Madrid System lets an owner file once and designate the countries where protection is wanted; each designated office then examines the mark under its own law. Searching the register therefore answers three questions at once: who already uses a name like yours internationally, where they hold it, and where they were refused, the last being the cheapest lesson available before you choose your own designations.
How this differs from WIPO's Global Brand Database
- Fuzzy, not exact. Trigram similarity finds NORTHWYND and NORTH WIND when you type Northwind; the official database needs the right term.
- Class-aware. Filter to your Nice classes, because a similar name in an unrelated class rarely matters.
- Outcomes on the row. Designated and refused offices per registration, without opening each record.
- Logos too. The same search by image that covers the U.S. register covers the Madrid logos.
- Linked to the record. Every result opens the full registration, with a link to WIPO's own entry.
Data scope: international registrations under WIPO's Madrid System, updated from WIPO's daily files. Not covered: marks filed directly at national offices or at the EUIPO. Similarity is a first-pass signal, not a clearance opinion.
Questions
Is this the same as WIPO's Global Brand Database?
It searches the same Madrid System registrations, but differently: fuzzy and phonetic matching rather than exact terms, results filtered by Nice class, and for each registration the countries it was designated in and the ones that refused it. WIPO's database is the authoritative record and every result links to it.
What does an international trademark search cover?
The 592,895 international registrations filed through WIPO's Madrid System, updated from WIPO's daily files. It does not cover marks filed directly at a national office (a German mark filed only at the DPMA, say) or at the EUIPO. Those live in national and EU databases.
Can I search international trademarks by logo?
Yes. Upload the artwork in the logo section below and it is compared against 275,753 Madrid registrations with a logo image as well as the U.S. register: by image structure, by what the image depicts and by the wording inside it.
Why does a Madrid registration show "refused in" some countries?
A Madrid registration is a bundle of national requests. Each designated office examines the mark under its own law and can refuse it, wholly or in part, while other offices accept it. The refused-in column is where the same mark hit a wall, which is useful when you plan your own designations.
Does an international registration block my U.S. application?
Only if it designates the United States; then it sits on the USPTO register like any other application and is already part of our U.S. name check. A Madrid registration that skips the U.S. is a signal about who owns the name abroad, not a U.S. conflict.
