How to Do a Trademark Search for Your Startup Name (2026 Guide)
Knowing how to do a trademark search for your startup name can save you from a forced rebrand, a cease-and-desist letter, or years of legal costs — all before you spend a single euro on branding.
Most founders skip this step entirely. The ones who don't often do it wrong — checking only one database, searching only exact matches, or missing the "confusingly similar" standard that trademark law actually uses.
If you're serious about using a name, run a proper screening before you buy domains or register a company. NameProof delivers a structured brand safety report within 24 hours for €19.
⚠️ This guide covers preliminary trademark screening — not legal advice. If your name clears these checks, consult a trademark attorney before significant brand investment. A preliminary search tells you whether to proceed. An attorney tells you whether it's safe to build on.
Why Trademark Search Matters Before You Register
Registering your company name as an LLC, Ltd, or SRL does not give you trademark protection. These are two completely separate legal systems that don't communicate with each other.
A trademark gives you exclusive rights to use a name commercially in connection with specific goods and services. Without it — or without checking for existing ones — you're building on ground someone else may already own.
The risk isn't just identical names. Trademark law uses a "likelihood of confusion" standard: a name that sounds similar, looks similar, or creates similar impressions in the same industry can trigger a conflict. This is where most founders get surprised.
The Three Databases You Must Search
USPTO — United States Patent and Trademark Office
The primary database for US trademark registrations. Use TESS (Trademark Electronic Search System) to search active and inactive marks. Essential if you plan to operate in the US market — which for most SaaS and digital products means almost always.
EUIPO — European Union Intellectual Property Office
Covers all 27 EU member states with a single search. A trademark registered here is valid across the entire European Union. Search this database if you're targeting any European market or plan to expand there.
WIPO — World Intellectual Property Organization
The international database covering trademarks filed under the Madrid System — a single application covering multiple countries simultaneously. A mark here may have protection in dozens of countries even without local registration.
Step-by-Step: How to Search Each Database
Search your exact name first
Start with an exact match search in all three databases. Use your brand name in quotes to find precise results. Note any active registrations, the trademark class (industry category), and the geographic coverage.
Search phonetic and visual variations
Trademark law covers "confusingly similar" names — not just identical ones. Search variations of your name: different spellings, similar-sounding words, and abbreviations. If your name is "Velorix", search "Velocrix", "Veloric", "Velorex" and similar variants.
Filter by trademark class
Trademarks are organized into 45 classes under the Nice Classification system. A conflict in Class 25 (clothing) is irrelevant if you're building software (Class 42). Filter results to your specific class — and check adjacent classes if your product could reasonably expand there.
Check status: active vs. expired
Not all registered trademarks are active. Some have expired, been abandoned, or cancelled. An expired trademark in your category is significantly less risky than an active one — though prior use rights can still apply in some jurisdictions. Always check the status field in search results.
Google the name for unregistered use
A company doesn't need a trademark registration to have enforceable rights in some jurisdictions — particularly the US, where common law trademark rights can arise from commercial use. Search your name on Google, check for active businesses, and look for consistent commercial use before concluding the name is clear.
Validate this name before you commit
NameProof checks trademark conflicts, domains, pronunciation and brand risks in one structured report. Delivered within 24 hours. Built for founders who want to launch once, not rebrand later.

Identical name, same class, same territory
This is a hard conflict. Consider the name taken and move to your next candidate. The cost of fighting or working around this is almost never worth it at the startup stage.
Similar name, same class, same territory
This requires judgment. The closer the phonetic or visual similarity, and the more direct the industry overlap, the higher the risk. Consult a trademark attorney before proceeding — the cost of an hour of legal advice is far lower than a forced rebrand.
Identical name, different class or territory
Lower risk, but not zero. Consider whether your business is likely to expand into that territory or category. If yes, the conflict becomes relevant as you scale. Document your reasoning and consult an attorney if the investment becomes significant.
Expired registration, same class
Check when it expired and whether the company is still operating under that name. If the original owner abandoned the mark and has no active commercial presence, the risk is lower — but not eliminated in all jurisdictions.
Important: Finding no results in a trademark database does not mean the name is legally clear. Unregistered use, pending applications, and jurisdiction-specific rules all create risk that a database search alone won't reveal. Always involve a trademark attorney before significant brand investment.
How Long Does a Trademark Search Take?
A basic search across three databases takes 45–90 minutes per name candidate — longer if you find potential conflicts that require deeper investigation. For three candidates, expect half a day of careful research before you can draw conclusions.
The time investment is worth it. A trademark conflict discovered before you register costs nothing to resolve. The same conflict discovered after you've built brand equity, printed materials, and acquired customers can cost tens of thousands to fix.
