How to Check if a Business Name Is Trademarked (Free Guide)

You have spent weeks brainstorming the perfect name for your startup. You have checked that the domain is available, you love the way it sounds, and you are ready to build your brand around it. Then, three months after launch, a law firm sends you a cease-and-desist letter demanding you stop using the name immediately.

This is not a hypothetical scenario. It happens to thousands of founders every year, and the consequences range from expensive legal battles to a complete rebrand that erases months of marketing equity. A forced rebrand can cost a startup anywhere from $10,000 to $100,000 or more when you factor in new design assets, reprinted materials, updated legal documents, lost SEO authority, and confused customers.

The good news: you can avoid all of this with a simple trademark search before you commit to a name. The entire process takes less than thirty minutes, costs nothing, and could save your business. In this guide, we will walk through exactly how to check if a business name is trademarked, step by step, using the free tools available to every founder.

We will use a running example throughout this guide. Imagine you are launching a SaaS platform called Nexify and want to make sure the name is safe to use.

What Is a Trademark and Why Should You Care?

A trademark is a word, phrase, symbol, or design that identifies and distinguishes the source of goods or services. Think of it as a legal claim on a brand identity within a specific market. When Nike uses its swoosh, that trademark tells consumers they are buying an authentic Nike product. When you name your startup, you are creating a trademark whether you formally register it or not.

This is an important distinction that trips up many founders: trademarks, domain names, and business registrations are three completely separate things.

• Domain name registration (through a registrar like Namecheap or GoDaddy) gives you the right to use a specific web address. It does not grant any trademark rights.
• Business name registration (through your state's Secretary of State) allows you to legally operate under a name. It does not grant federal trademark protection.
• Trademark registration (through the USPTO) gives you exclusive rights to use a name in connection with specific goods or services across the entire United States.

You can register a domain, file a business name with your state, and still get hit with a trademark infringement claim if someone else already holds rights to a similar name in your industry.

There are also two types of trademark rights in the United States:

• Common law trademarks are created automatically when you use a name in commerce. These are limited to the geographic area where you actually do business and are harder to enforce.
• Registered trademarks are filed with the USPTO and provide nationwide protection, the legal presumption of ownership, and the ability to sue in federal court.

Even if a competitor has not registered their mark with the USPTO, they may still have common law rights that could cause problems for you. That said, a USPTO search is the most important first step because registered marks carry the strongest legal weight and are the easiest to discover.

How to Search the USPTO Trademark Database (Step-by-Step)

The United States Patent and Trademark Office maintains a free, public database of every trademark application and registration in the country. Here is how to search it for your business name.

Step 1 — Go to the USPTO Trademark Search

Navigate to the USPTO's Trademark Electronic Search System. The USPTO has been modernizing its search tools, so you may find their newer search interface at tsdr.uspto.gov or the traditional TESS system. Both allow you to search the full federal trademark database at no cost.

You do not need to create an account or log in. The database is completely public.

Step 2 — Choose "Basic Word Mark Search"

You will see several search options. For most founders, the Basic Word Mark Search (sometimes called "Word and/or Design Mark Search") is the right starting point. This searches for trademarks that contain your text string, regardless of any logos or design elements attached to them.

Avoid the "Structured" or "Free-form" searches for now. These are built for trademark attorneys who need to construct complex Boolean queries. The basic search handles 90% of what you need.

Step 3 — Enter Your Name and Review Results

Type your business name into the search field. For our example, enter Nexify.

A few important search tips:

• Search for the exact name first, then try variations. If your name is "Nexify," also try "Nexifi," "Nexafy," and "Nexify Technologies."
• Try phonetic equivalents. Trademark law considers names that sound alike to be potentially confusing, even if they are spelled differently. "Nexify" and "Nexifi" could be considered confusingly similar.
• Search with and without spaces. "Match My Domain" and "MatchMyDomain" may return different results.
• Drop common suffixes. Searching "Nexify" is better than "Nexify Inc." or "Nexify App" because suffixes can hide relevant results.

The search will return a list of matching or similar trademark records. Each result shows the mark's text, its registration number, the filing date, and its current status.

Step 4 — Check the Status and Nice Classification

Click on each relevant result to see its full details. Pay close attention to two things:

• The Nice Classification (International Class). Trademarks are registered within specific classes of goods or services. A trademark for "Nexify" in Class 25 (clothing) does not necessarily block you from using "Nexify" in Class 9 (software). More on this in the next section.
• The description of goods and services. Even within the same class, the specific description matters. A Class 9 registration for "Nexify" covering "downloadable mobile games" is less threatening to your SaaS analytics platform than one covering "software as a service for business data analytics."

Step 5 — Look for Dead vs. Live Marks

Every trademark record has a status. The two most important categories are:

• Live — The mark is currently active, either registered and maintained or pending approval. Live marks are the ones you need to worry about.
• Dead — The application was abandoned, the registration expired, or it was canceled. Dead marks are generally safe to ignore, though there are exceptions if the original owner is still using the name in commerce (common law rights).

If your search for "Nexify" returns three results—one dead mark in Class 9, one live mark in Class 25 (clothing), and one live mark in Class 35 (advertising services)—here is how to read the situation:

• The dead Class 9 mark is likely not a threat, but worth noting.
• The live Class 25 mark is in a completely different industry, so it probably does not affect your software startup.
• The live Class 35 mark is the one that demands attention. If your SaaS product could be classified under advertising or business management services, this is a potential conflict.

When in doubt about whether a live mark poses a real conflict, consult a trademark attorney. The initial search is something you can and should do yourself, but interpreting borderline cases is where professional advice pays for itself.

Understanding Trademark Classes (Nice Classification)

The Nice Classification system divides all goods and services into 45 classes (34 for goods, 11 for services). When a company registers a trademark, they register it within one or more specific classes. This is why multiple companies can use the same name in different industries without conflict: Delta is both an airline and a faucet brand, and Apple is both a technology company and a record label (though that one did eventually cause some legal tension).

If you are building a tech startup, these are the classes you will encounter most often:

• Class 9 — Computer software, downloadable applications, mobile apps. This is the broadest software class and covers most products you can install or download.
• Class 35 — Advertising, business management, and administration services. Many SaaS companies register here because their software helps businesses manage operations, marketing, or data.
• Class 42 — Scientific and technological services, including SaaS platforms, cloud computing, software design, and IT consulting. This is where most cloud-based software products belong.
• Class 38 — Telecommunications services, including messaging platforms, chat apps, and communication tools.
• Class 36 — Financial services, fintech, insurance, payment processing.

Back to our example: if you are launching Nexify as a SaaS analytics platform, you would primarily be concerned about existing marks in Classes 9, 35, and 42. A live "Nexify" registration in Class 25 (clothing) would not block you. But a live registration in Class 42 for "software as a service" would be a serious red flag.

Keep in mind that trademark protection can extend beyond the exact class of registration. The legal standard is "likelihood of confusion"—would a reasonable consumer be confused about the source of the goods or services? If your software startup shares a name with a well-known brand in a related industry, confusion could be argued even across different classes.

Beyond the USPTO — Other Places to Check

The federal trademark database is the most important resource, but it does not capture everything. Here are the other places a thorough trademark search should cover:

State Trademark Databases

Each U.S. state maintains its own trademark registry, separate from the federal USPTO system. State registrations provide protection only within that state's borders, but they still represent legitimate trademark claims. Search your state's Secretary of State website for their trademark database. If you plan to operate nationally, check the states where your largest competitors or customer bases are located.

International Marks (WIPO Global Brand Database)

If you have any plans to operate internationally, search the World Intellectual Property Organization (WIPO) Global Brand Database at branddb.wipo.int. This free tool searches trademark registrations from over 70 national and regional trademark offices. A company with a registered trademark in the EU or UK could potentially block your expansion into those markets.

Common Law Searches (Google and Social Media)

Not every trademark is registered. Many businesses operate under unregistered names and still hold common law rights. Run a thorough Google search for your proposed name. Look for:

• Existing businesses using the same or a very similar name
• Social media accounts on major platforms (Instagram, X, LinkedIn, TikTok)
• App store listings on Apple's App Store and Google Play
• Product listings on Amazon and other marketplaces

MatchMyDomain's Social Handle Checker can quickly scan whether a name is already claimed across major platforms, which doubles as a common law trademark indicator.

Amazon Brand Registry

If you sell physical or digital products on Amazon, check the Amazon Brand Registry. Brands registered there have additional intellectual property protections within the Amazon ecosystem, and Amazon takes trademark claims seriously. A conflict here can get your product listings removed.

You can also use our Name Validator to run a comprehensive check across domains, social handles, and web presence in one step—giving you a quick initial read on whether a name is already heavily used in the market.

The Automated Shortcut

Manually searching TESS, state databases, WIPO, and Google is thorough, but it is also time-consuming. If you are evaluating multiple name candidates (which you should be), the process multiplies quickly.

This is exactly why we built Trademark Radar into MatchMyDomain. It searches live USPTO filings automatically, flags potential conflicts by class, and gives you a risk assessment in seconds rather than hours. You get a clear summary of live marks, their classes, and how they relate to your intended use—all without leaving the platform.

What to Do If a Similar Mark Exists

Finding a similar trademark does not automatically mean your name is off-limits. Here is how to evaluate the situation:

When It Is Probably Safe

• The mark is dead and has been for years. If a registration was abandoned or canceled and you cannot find evidence the name is still being used in commerce, you are generally in the clear. However, proceed with caution—a recently abandoned mark may still have residual common law rights.
• The mark is in a completely unrelated class. "Nexify" registered for agricultural equipment (Class 7) poses minimal risk to a SaaS startup. The goods and services are so different that consumer confusion is unlikely.
• The mark is a weak or descriptive term. Generic or highly descriptive names ("Quick Clean," "Best Price") receive weaker trademark protection. A competitor using a similarly descriptive name may not be able to stop you, especially in a different market.

When It Is Risky

• The mark is live and in the same or a related class. A live "Nexify" registration in Class 42 (technology services) is a direct conflict with your SaaS platform. Do not ignore this.
• The mark owner is a large, well-funded company. Even if the legal merits are debatable, defending against a trademark infringement claim from a company with deep pockets is expensive and distracting. Pragmatism matters.
• The name is famous or well-known. Famous marks receive broader protection than ordinary ones. You cannot name your software startup "Kleenex" or "Rolex" regardless of the class.
• The mark is phonetically identical. Courts evaluate trademarks based on sound, appearance, and meaning. "Nexify" and "Nexifi" would likely be considered confusingly similar even though the spelling differs.

When to Consult a Trademark Attorney

If your search turns up a live mark in a related class and you are unsure whether it poses a real threat, invest in a professional trademark opinion. A trademark attorney can provide a formal "likelihood of confusion" analysis that accounts for the strength of the existing mark, the similarity of the goods and services, the overlap in marketing channels, and other legal factors. This typically costs between $500 and $1,500—a fraction of what a forced rebrand would cost.

Consider a Different Name

Sometimes the smartest move is to pick a new name. If the trademark landscape is crowded or a clear conflict exists, going back to the naming stage is far cheaper than fighting a legal battle later. Use Name Studio to generate fresh ideas, check out our guide on how to name a startup, or review our startup branding checklist to make sure your next pick is solid from every angle.

And once you have a new candidate, run it through the domain checker and Trademark Radar before you fall in love with it.

Frequently Asked Questions

Is it free to search for trademarks?

Yes. The USPTO's trademark search tools are completely free and open to the public. You do not need an account, a law degree, or any special software. International databases like the WIPO Global Brand Database are also free. What you are paying for when you hire a trademark attorney is not the search itself, but the professional interpretation of the results.

Can two businesses have the same name?

Yes, but only if they operate in different industries (different trademark classes) and there is no likelihood of consumer confusion. "Delta" exists simultaneously as an airline, a faucet company, and a dental insurance provider. However, the closer two businesses are in their products, services, or customer base, the more likely a shared name will cause legal problems. If you want to check whether your proposed name is already taken as a business name, you should search both trademark databases and state business registries.

Does registering a domain name give me trademark rights?

No. Domain registration and trademark registration are completely independent legal processes governed by different authorities. Owning nexify.com does not give you trademark rights to the word "Nexify," and having a trademark on "Nexify" does not automatically entitle you to the domain. That said, trademark holders can sometimes reclaim domains through UDRP (Uniform Domain-Name Dispute-Resolution Policy) proceedings if they can prove the domain was registered in bad faith.

How long does it take to register a trademark?

The USPTO trademark registration process typically takes 12 to 18 months from initial filing to registration. The timeline includes an examination period (about 3-4 months after filing), a 30-day opposition window where third parties can challenge your application, and the final registration step. You can begin using the TM symbol (which indicates an unregistered, claimed trademark) as soon as you start using the name in commerce, but the registered trademark symbol (®) can only be used after the USPTO formally grants your registration.
