Check a Brand Name: Find Similar EU Trademarks Before You File
Use AI to check whether similar trademarks are registered in the EUIPO — before investing in filing and branding.
Why you should check your brand name before filing
A memorable brand name is valuable — but only if it's not already protected. Millions of trademarks are registered in the EUIPO alone. Filing without preliminary research risks oppositions, cease-and-desist letters, and losing your entire branding investment.

What happens if you don't check?
After filing, your trademark is published. Any owner of an older, similar mark can file an opposition. The consequences: attorney fees (€5,000–15,000), lost filing fees, and a name you can't use. A preliminary check costs a fraction of that.

FAQ: Trademark Checking
Yes, the public quick search is free and requires no registration: enter your desired name and instantly see whether identical or noticeably similar trademarks exist in the EUIPO register. For the full AI check with a similarity score per hit, class comparison, and PDF report there is a one-time paid pass — no subscription.
The AI analysis takes a few seconds: the tool compares your name against roughly 1.6 million active trademarks in the EUIPO register and returns a results list sorted by similarity score. So you not only see whether there are hits, but also which ones come closest to your name in sound and appearance.
The similarity score shows, in percent, how closely a found trademark matches your desired name. The rating combines sound (how similar the names are when spoken), appearance (how similar they look), and industry overlap via the Nice classes. This lets you see at a glance which hits deserve a closer look. The score does not replace a legal assessment of a conflict.
No, there is no legal obligation to search — neither the DPMA nor the EUIPO examine at filing whether earlier similar trademarks exist. That is exactly the risk: owners of earlier rights can file an opposition or send a cease-and-desist letter, and filing fees are not refunded. A pre-filing search is therefore the most important step before any application; when in doubt, have critical hits reviewed by a lawyer.
