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:

  1. The exact name
  2. Common spelling variants (e.g., "scroll" vs "skroll")
  3. Phonetic equivalents — marks are refused or opposed for confusing similarity in sound, not just spelling
  4. 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
