How to Check If a Name Is Trademarked Before You Use It
Updated
To check whether a name is trademarked, search the official trademark registers for the countries where you'll sell, using the exact name plus close spelling and sound-alike variants, and filter results by the goods or services class you actually offer. A name is only "taken" in the classes where someone holds a live registration or pending application for similar goods or services — the same word can be free in one class and blocked in another. This guide covers the registers to use, how to read what you find, and when a search result means you should pick a different name.
Step 1: Define what the name will cover
Trademark rights are tied to specific goods and services, grouped into numbered classes under the Nice Classification. Before searching, write down:
- What you're selling (a SaaS tool, a coffee brand, an apparel line)
- Which classes that maps to (e.g., class 9 for software, class 25 for clothing, class 30 for coffee)
- Which countries or regions you'll actually sell in — trademark rights are territorial, so a US registration doesn't block someone in the EU
This step decides which registers matter and which results you can ignore. A clothing brand and a software company can often both use the same word because they sit in different classes.
Step 2: Search the official trademark databases
Use the free government and intergovernmental registers rather than relying on a single commercial tool. The main ones:
| Register | Coverage | Notes |
|---|---|---|
| USPTO TESS / Trademark Search | United States | Federal registrations and applications |
| EUIPO eSearch | European Union | Covers EU trade marks |
| WIPO Global Brand Database | International / multi-office | Aggregates many national registers in one search |
| UKIPO, IP Australia, CIPO, etc. | Individual countries | Use for markets outside the US/EU |
Search each register with:
- The exact name
- Common spelling variants (e.g., "scroll" vs "skroll")
- Phonetic equivalents — marks are refused or opposed for confusing similarity in sound, not just spelling
- Wordmark and logo/figurative marks separately, since a name can be protected as a design even if the plain word isn't registered
For each hit, open the record and note the status, the class(es), the owner, and the filing/registration dates.
Step 3: Read the results correctly
Not every search hit is a conflict. Check these fields:
- Status — "Registered" and "Pending/Application" are live risks. "Dead," "Abandoned," or "Cancelled" marks generally no longer block you, though common-law rights can still exist.
- Class — does the registration cover goods or services similar to yours? A mark in an unrelated class is usually not a conflict.
- Goods/services description — read the actual wording, not just the class number. "Software for medical billing" is narrower than "software."
- Owner and dates — a large company with a broad portfolio may enforce aggressively even outside its exact class.
- Territory — a registration in a country you don't sell in doesn't stop you there.
Record the serial/registration number, status, class, and a screenshot or PDF of each relevant result. This is your evidence if you later need a lawyer's opinion or want to show you searched in good faith.
Step 4: Check availability beyond trademarks
A trademark search is necessary but not sufficient. The same name can be blocked by a domain, an app store listing, or a social handle even when no trademark exists. Tools like NameSpyAI run a name through trademarks, domains, app stores, social handles, and other sources in one report — its site notes that 60% of names checked in a recent week had a possible trademark conflict, and it offers a small number of free searches before paid, pay-as-you-go credits. Whether you use a tool or check manually, cover:
- The .com and your target country domains
- Apple App Store and Google Play listings
- Handles on the platforms you'll actually use
- Company registries if you're forming a legal entity
Step 5: Decide, and know when to get help
- No live marks in your classes and territories, and the domains/handles are free — the name looks usable; proceed and consider filing your own application.
- A pending or registered mark in a similar class — treat it as a conflict. Rename, or get a lawyer's clearance opinion before spending on branding.
- Only dead marks or unrelated classes — usually fine, but common-law (unregistered) rights can still exist in some countries, so keep your search records.
A free search is a screening step, not legal clearance. If you're investing in a brand, packaging, or a launch, have a trademark attorney review the results — they can assess likelihood of confusion, common-law exposure, and filing strategy, which a database search alone can't.
Common pitfalls
- Searching only the exact spelling and missing phonetic equivalents
- Ignoring the class and treating any hit as a blocker, or any miss as safe
- Checking only your home country when you sell internationally
- Assuming a dead mark means the name is free — common-law rights may persist
- Skipping domains, app stores, and handles because the trademark search came back clean
