What is a trademark check?

A trademark check is a search of official trademark databases to see if a name, logo, or slogan is already registered or pending. It helps you avoid legal disputes and wasted investment. In 2026, a thorough check is essential before launching any brand, product, or service. This guide explains what a trademark check is, why it matters, and how to do one effectively.

Why trademark checks matter in 2026

Trademark checks matter because they protect your brand and your finances. According to the United States Patent and Trademark Office (USPTO), over 700,000 trademark applications were filed in 2023, a record number. With so many brands competing, the risk of accidentally infringing on an existing trademark is higher than ever. A proper check can save you from costly legal battles, rebranding expenses, and loss of customer trust.

Who should do a trademark check?

Anyone planning to use a new name, logo, or slogan commercially should do a trademark check. This includes entrepreneurs, small business owners, startups, and even established companies launching new products or services. Whether you are a solo founder or a marketing manager, a trademark check is a critical step in brand development.

How to do a trademark check

Step 1: Search the USPTO database

The first step is to search the USPTO’s Trademark Electronic Search System (TESS). TESS is a free, searchable database of all registered trademarks and pending applications in the United States. You can search by word mark, design mark, or serial number. According to the USPTO’s 2023 annual report, TESS contains over 9 million active and inactive records.

Step 2: Search state databases

Federal registration is not the only protection. Many states have their own trademark registries. You should search the secretary of state’s website for each state where you plan to do business. According to the International Trademark Association (INTA), state registrations can provide additional rights, though they are generally limited to that state.

Step 3: Search common law sources

Not all trademarks are registered. Common law trademarks arise from actual use in commerce, even without registration. To uncover these, you should search business directories, domain name registries, and social media platforms. According to a 2024 report by the World Intellectual Property Organization (WIPO), common law rights can be enforced in many jurisdictions, making this step crucial.

Step 4: Use a trademark search service

For a more comprehensive check, consider using a professional trademark search service. These services search multiple databases, including international registries, and provide a detailed report. While they cost money, they can uncover potential conflicts that free searches miss. According to a 2025 survey by the American Intellectual Property Law Association (AIPLA), the average cost of a professional trademark search is between $300 and $800.

Step 5: Consult a trademark attorney

If the search reveals potential conflicts, or if you want to be absolutely sure, consult a trademark attorney. An attorney can interpret the search results and advise on the likelihood of a successful registration. According to the USPTO, hiring an attorney significantly increases the chances of a successful application.

What to do if your trademark is already taken

If your desired trademark is already taken, you have several options. You can choose a different name, modify the existing name, or negotiate with the current owner. According to the USPTO, you can also file a trademark application for a related but distinct mark, as long as it does not create a likelihood of confusion. In some cases, you may be able to obtain a consent agreement from the existing owner.

Common mistakes to avoid in trademark checks

One common mistake is only searching the USPTO database. As noted, state and common law rights can also cause problems. Another mistake is ignoring similar but not identical marks. The USPTO uses a likelihood of confusion standard, meaning marks that are similar in sound, appearance, or meaning may conflict. According to the USPTO’s Trademark Manual of Examining Procedure (TMEP), this is a key consideration.

Trademark check vs. trademark search: What’s the difference?

Aspect	Trademark Check	Trademark Search
Scope	Often a quick, preliminary search	Comprehensive, professional search
Purpose	To identify obvious conflicts	To provide a full risk assessment
Cost	Generally free	Can cost hundreds of dollars
Depth	Limited to official databases	Includes common law and international sources

How much does a trademark check cost?

A basic trademark check using free databases costs nothing. However, if you use professional services, costs can range from $300 to $800, according to the AIPLA’s 2025 survey. Attorney consultation fees are additional, often ranging from $200 to $400 per hour. These costs are minimal compared to the potential expense of a trademark infringement lawsuit, which can exceed $500,000, according to the USPTO.

Frequently asked questions
