Is My Business Name Trademarked? How to Check in 2026

You've got a business name you love. Maybe it came to you in the shower, or maybe you spent weeks brainstorming with your co-founder. Either way, before you commit, you need to answer one critical question: is this name already trademarked?

A trademark conflict can force you to rebrand months or years after launch — an expensive and demoralizing process. The good news is that checking trademark registries has never been easier. Here's your complete guide to doing it right.

Free Trademark Search Tools

The world's three largest trademark registries all offer free, public search tools. You don't need to hire a lawyer or pay for a service to get started.

USPTO Trademark Electronic Search System (TESS)

The United States Patent and Trademark Office maintains TESS, a free database of all active and recently expired US trademark registrations and pending applications.

How to use it:

1. Go to tmsearch.uspto.gov
2. Select "Basic Word Mark Search"
3. Enter your business name in the search field
4. Review the results, paying attention to live marks (not dead/abandoned ones)

Pro tip: Search for your exact name first, then try variations. If your name is "Bolt Analytics," also search for "Bolt" alone, "Bolt Analytix," and any phonetic equivalents.

EUIPO eSearch Plus

The European Union Intellectual Property Office's eSearch Plus database covers trademarks registered across all 27 EU member states through a single search.

How to use it:

1. Visit euipo.europa.eu/eSearch
2. Click on "Trade marks" in the left panel
3. Enter your business name and search
4. Filter by status to focus on active registrations

EUIPO covers EU-wide trademarks (EUTMs), but individual EU countries may also have national registrations that don't appear here. For most startup purposes, EUIPO is sufficient, but if you're specifically targeting one EU market, consider checking that country's national registry as well.

UK IPO Trademark Search

Since Brexit, UK trademarks are separate from EUIPO registrations. If you're operating in the UK market, you need to check both.

How to use it:

1. Go to trademarks.ipo.gov.uk
2. Use the search function to look up your business name
3. Review results for active marks in relevant classes

What to Look For in Search Results

Finding results doesn't automatically mean your name is taken. Here's how to evaluate what you find.

Exact Matches

An exact match for your name in the same industry category is the clearest red flag. If someone has registered "Bolt Analytics" for software services and you want to launch "Bolt Analytics" as a software company, that's a serious conflict.

However, context matters. Check the status of the registration:

• Live/Active: This trademark is currently in force. Proceed with extreme caution.
• Pending: Someone has applied but hasn't received registration yet. Still a significant risk.
• Dead/Abandoned/Expired: The owner didn't renew or abandoned the application. This is generally less concerning, but doesn't guarantee the name is clear — the owner may still have common-law rights from actual use.

Phonetic Similarities

Trademark law doesn't just protect exact matches — it protects against "confusingly similar" marks. This includes names that sound alike even if spelled differently.

"Bolt" and "Boult," "Nombrio" and "Nombrea," "TechVault" and "TekVault" — these could all be considered confusingly similar. When searching, think about how your name sounds, not just how it's spelled.

Try these variations:

• Different spellings of the same sound (ph vs. f, k vs. c)
• Dropped or added vowels
• Common prefixes and suffixes added or removed

Same Nice Class

The Nice Classification system organizes goods and services into 45 classes. A trademark registered for "Bolt" in Class 25 (clothing) is very different from "Bolt" in Class 9 (software).

When evaluating search results, always check which Nice classes the existing trademark covers. If they're in a completely unrelated class to your business, the conflict is much less concerning — though not nonexistent, especially if the existing mark is well-known.

Key classes for tech startups:

• Class 9: Computer software, apps, downloadable digital content
• Class 35: Business management, advertising, office functions
• Class 38: Telecommunications, internet services
• Class 42: Software as a service (SaaS), technology consulting, cloud computing

If an existing mark covers any of these classes and your startup operates in tech, you need to look closely.

When Results Are Concerning

Take the following situations seriously:

• Exact or near-exact match in the same or related Nice classes — this is the highest risk scenario. Proceeding could result in a cease-and-desist or infringement lawsuit.
• Same name in a different but adjacent class — for example, your SaaS is in Class 42 but someone has the name in Class 35. These classes are often considered related by trademark examiners.
• A well-known brand with the same name in any class — famous marks like Apple, Nike, or Google receive broader protection across all classes.
• Multiple registrations of the same name across different owners — this suggests the name is common in commerce and may face opposition from multiple directions.

When Results Are Likely Safe

These scenarios are generally lower risk:

• No results found across all three major registries — while not a guarantee (common-law trademarks exist), this is a strong positive signal.
• Only dead or expired marks — previous registrations that were abandoned or not renewed suggest the name space is becoming available, though you should understand why they were abandoned.
• Matches only in completely unrelated classes — "Bolt" for agricultural equipment (Class 7) is unlikely to conflict with your software startup, though this isn't absolute.
• Matches only in distant geographic markets you don't plan to enter — a registration only in Japan when you're only targeting the US and EU, for example.

When to Consult a Trademark Attorney

While free searches and automated tools can catch the most obvious conflicts, there are situations where professional help is worth the investment:

• Ambiguous results: You found a similar (but not identical) name in a related (but not identical) class. An attorney can assess the actual likelihood of confusion.
• High stakes: You're about to invest significant capital in branding, marketing, or a product launch. The cost of an attorney opinion ($500-$2,000) is a rounding error compared to a forced rebrand.
• International expansion: You're planning to operate in multiple jurisdictions and need to understand the interplay of different trademark systems.
• Filing your own trademark: An attorney can help you choose the right classes, draft your description of goods/services, and navigate the application process to maximize your chances of approval.

A trademark attorney can also conduct a more thorough search that includes common-law marks, state-level registrations, and business name databases that public tools may miss.

The Modern Approach: Automated Clearance

Manually searching three different registries, parsing results, and understanding Nice classifications is tedious and error-prone. This is exactly the kind of task that modern tooling can streamline.

Automated trademark clearance tools can search multiple registries simultaneously, flag phonetic similarities, cross-reference Nice classes, and present results in a clear, actionable format — turning hours of manual research into seconds.
