How to Check If a Domain Is Trademarked
A domain registration and a trademark are two different systems that do not talk to each other. The registrar will happily sell you a domain that someone else has trademarked — and the trademark owner can still come after you. Check before you build on it.

- Search the USPTO database: look up the name (without the .com) in the USPTO trademark search. You are looking for live marks, not dead ones — and for marks in classes related to what you plan to do with the domain, not just exact duplicates.
- Understand "likelihood of confusion": trademark conflicts are not decided by identical spelling. Similar sound, similar meaning, or similar appearance in a related industry can all count. "Likely to confuse customers" is the standard, not "exact match". This is general information, not legal advice.
- Check internationally if it matters: the USPTO covers the US. For other markets, WIPO's Global Brand Database covers multiple national registries at once. If you plan to sell globally, one country's clearance is not enough.
- Search the web for common-law use: some trademark rights come from use, not registration. A business actively trading under the name for years may have enforceable rights even with no USPTO record — a plain web search for the name plus the industry is worth doing.
What a conflict actually means
- Not every conflict is fatal: the same name can coexist across unrelated industries. The question is always the industry overlap and the confusion risk, not the name alone.
- The worst time to find out is after launch: UDRP domain disputes and cease-and-desist letters arrive after you have invested in the site, the SEO, and the brand. A pre-screen costs little; a forced rebrand costs everything built on the domain.
- Registration date is not the whole story: a later-filed trademark can still win against an earlier-registered domain if the mark owner's use predates yours in the relevant market.
FAQ
Does owning the .com give me trademark rights?
No. Domain registration gives you the address; trademark rights come from use in commerce and/or registration with a trademark office. The two systems are independent. This is general information, not legal advice.
Can I keep a domain that matches someone's trademark?
It depends on the industry overlap, your use, and their enforcement. Holding a domain that matches a famous mark to sell it back is cybersquatting and loses disputes; using a similar name in an unrelated field often coexists. When in doubt, a trademark attorney's opinion costs less than a dispute.
