You’ve spent months developing your brand name. You’ve registered the domain, designed the logo, and you’re ready to announce it to the world. But here’s the question most entrepreneurs skip — and one that can cost them everything: does someone else already own the rights to that name?

A trademark search is the single most important step you can take before launching a brand. Skipping it doesn’t just put your registration at risk — it can expose your business to an infringement lawsuit, force an expensive rebrand, and wipe out every dollar you’ve invested in marketing.

In this guide, you’ll learn exactly how to conduct a trademark search, what to look for, and why a professional search goes further than a free online tool.

A real story: what happens when you skip the search

Before we get into the how-to, I want to share a story that illustrates exactly what’s at stake.

CLIENT CASE STUDY One of my clients is an online course creator who started her business six years ago. She was in love with the name she chose — it felt perfect for her brand. She didn’t consult an attorney or do a trademark search before she launched.  Over the past two years, her business skyrocketed. She built a following, scaled her courses, and earned customers all over the United States. She assumed she was protected because she owned the website domain name.  She wasn’t.  A business operating in another state — in the same industry, under the same name — had federally trademarked it. My client received a cease and desist letter.  She was devastated when she called me. I hated to tell her that she would have to rebrand. Six years of brand equity, customer recognition, and marketing investment — gone, because a trademark search was never done.

This is not a rare situation. It happens every week to business owners who believe that owning a domain name, registering a business name with the state, or simply being first gives them legal rights. It doesn’t. Federal trademark registration is what creates nationwide protection — and the only way to know whether someone else holds it is to search before you launch.

Here is exactly how to do that.

Why a trademark search matters before launch

When you launch a brand without searching for existing trademarks, you’re gambling. Another business may already own federal rights to your name — or a confusingly similar one — in your industry. Under U.S. trademark law (15 U.S.C. § 1051 et seq.), the first party to use a mark in commerce and register it generally holds priority.

That means if someone else filed first, you could be ordered to stop using your brand name — even if you’ve been using it for months or years. As my client discovered, the financial consequences can be severe: legal fees, rebranding costs, lost revenue, and the erosion of years of customer trust.

A thorough trademark search conducted before you launch can prevent all of it.

Step 1: Start with the USPTO TESS database

The first place to search is the USPTO’s Trademark Electronic Search System (TESS), available free at USPTO.gov. This database contains all federally registered trademarks and pending applications.

Here’s how to search it effectively:

1. Go to USPTO.gov and navigate to the Trademark section, then select TESS
2. Use the Basic Word Mark Search for your exact brand name
3. Run a broader search for phonetically similar names and common misspellings
4. Filter results by the relevant International Class for your goods or services
5. Review both LIVE registrations and recently expired marks — expired marks can sometimes be revived

IMPORTANT: Finding no results in TESS does not mean your name is legally clear. TESS only shows federally registered marks — not common law rights, state registrations, or pending applications filed under different spellings. My client’s situation is proof of exactly this: a thorough search would have uncovered the conflict before she invested six years into a brand she ultimately had to abandon.

Step 2: Search beyond the USPTO

A complete trademark clearance search goes well beyond the federal database. Common law trademark rights can arise simply from using a name in commerce — even without registration. That means a business could have strong legal rights to a name you’ve never heard of.

Your expanded search should include:

• State trademark databases — many states maintain their own registries
• Business name registries — search your state’s Secretary of State database
• Domain registrations — a registered domain can signal prior use in commerce
• Social media handles — search Instagram, LinkedIn, Facebook, TikTok, and X
• Google and Bing — search the name plus your industry to find active businesses
• Industry directories and trade publications — especially in niche markets

This is precisely where my client’s situation fell apart. The competing business was operating under the same name in the same industry in another state. It wouldn’t necessarily appear at the top of a casual Google search in her market — but a professional search would have found it.

Step 3: Evaluate what you find

Finding a similar name doesn’t automatically mean you can’t use yours. Trademark law considers several factors when evaluating potential conflicts, commonly called the likelihood of confusion analysis.

Key factors include:

• Similarity of the marks — how close are the names visually, phonetically, and conceptually?
• Relatedness of goods or services — the same name can coexist across entirely different industries
• Strength of the existing mark — generic or descriptive names get less protection than distinctive ones
• Channels of trade — do both businesses reach the same customers in the same markets?

In my client’s case, both businesses operated in the same industry serving the same national audience. The marks were identical. There was no argument to be made. Had she consulted an attorney before launch, that analysis could have been done in an afternoon and she could have chosen a different name with no disruption to her business whatsoever.

This analysis requires legal judgment. Two marks that look similar on paper may not conflict legally and two marks that seem different may still create confusion in the marketplace. This is why a professional clearance opinion from a trademark attorney is strongly recommended before you invest in a brand.

Step 4: Search your specific trademark class

Every trademark is registered in one or more of 45 international classes that define the type of goods or services the mark covers. Your search should focus on the classes most relevant to your business.

For example, a clothing brand would search Class 25. A software company would look at Class 42. An educational services firm — like an online course creator — would check Class 41.

Searching the wrong class, or failing to search related classes, is one of the most common errors in DIY trademark searches. An attorney familiar with Nice Classification can identify every class that applies to your business model and make sure your clearance search is complete.

Step 5: Get a professional clearance opinion

A DIY search is a useful starting point, but it is not a substitute for a professional trademark clearance search and opinion.

Here’s why the professional search matters:

• Professional search firms access databases that aren’t publicly available, including common law usage records and international registries
• A trademark attorney can evaluate the legal risk of each conflict — not just flag its existence
• A written clearance opinion provides a legal record that you conducted due diligence, which can matter significantly in future disputes

My client spent six years and significant resources building her brand. A professional clearance search and attorney opinion would have cost a fraction of what the forced rebrand ultimately required — in both money and emotional toll. The search is not an optional step. It is the foundation of everything that comes after.

Frequently asked questions about trademark searches

How long does a trademark search take?

A basic TESS search can be completed in under an hour. A comprehensive professional clearance search, including common law review and a written opinion, typically takes 5–10 business days.

Is the USPTO trademark search free?

Yes, the USPTO’s TESS database is free to access at USPTO.gov. However, a professional clearance search conducted by a search firm and reviewed by an attorney involves a fee — typically ranging from a few hundred to over a thousand dollars depending on the complexity of your case.

Does owning the domain name protect my brand?

No. This is one of the most common misconceptions in trademark law — and one of the most costly. Domain ownership establishes no trademark rights whatsoever. Federal trademark registration is the legal protection that matters. Owning the domain name for a brand that someone else has trademarked will not prevent you from receiving a cease and desist letter.

What if my name isn’t in the USPTO database — am I safe?

Not necessarily. Common law trademark rights exist independently of federal registration. A business that has been using a name in commerce for years may have enforceable rights even without a federal registration on file. This is exactly the scenario that affects so many business owners who do only a basic TESS search.

Can I trademark a name that someone else is using but hasn’t registered?

In most cases, no. If another business has established common law rights through prior use, filing a federal registration doesn’t override those rights — and could expose you to legal action.

Do I need to search internationally?

If you plan to do business outside the United States, yes. Trademark rights are territorial, and a name that is clear in the U.S. may be registered by another party in Canada, the EU, or other markets. An attorney can advise on international search strategy based on your specific business model.

The story I shared at the beginning of this post is not an outlier — it is a pattern we see regularly. Business owners invest years into a brand name, only to discover too late that someone else holds the trademark.  A trademark search takes a few days. A rebrand can take years.  Our attorneys conduct professional trademark clearance searches and provide written opinions so you can launch — and grow — with complete confidence in your brand name.
