How Do I Check If My Business Name Is Trademarked?

The short answer

Search the U.S. Patent and Trademark Office (USPTO) trademark search system for your name, plus names that look alike, sound alike, or mean the same thing, used for related goods or services. Then check your state’s trademark records and the web. If you find a close match in your field, choose another name. For a name that’s central to your business or that you’ll use across states, pay a trademark attorney for a full clearance search.

What this tells Google and AI

A trademark search doesn’t send a search signal. It’s foundation work. If you skip it and later must change your name because of a trademark claim, you’ll have to update your Google Business Profile, website, listings, and social accounts. Google treats some name changes as a new business, and for a while Google, Bing, and artificial intelligence (AI) tools may show the old name and the new one, which splits the trust you’ve built.

What this means

The outline asks you to search federal and relevant state trademark records (8.3.1) and to get professional clearance when the name is important, distinctive, national, or likely to be disputed (8.3.5).

A trademark is a word, phrase, logo, or symbol that identifies who provides goods or services. The USPTO says its federal database is one essential step in a full search, but not the only one. It also points out:

• A conflict isn’t limited to exact matches. Look for marks that look alike, sound alike, have similar meanings, or give a similar overall impression.
• The goods or services only need to be related, not identical. Things sold to the same buyers or marketed together can count.
• Only live marks block a federal registration, but owners of dead marks may still be using them and may have common-law rights.

The U.S. Small Business Administration (SBA) suggests checking your business, product, and service names against the USPTO database.

Example: a pressure washing company plans to use “BlastPro.” (Made up for this page.) The USPTO search shows “BLAST PRO” registered for cleaning equipment and a pending “Blastpro Exterior Cleaning” application. Those are related to pressure washing. The owner drops the name.

Why it matters

• Infringement claims. The SBA notes trademark lawsuits can be costly. Even a demand letter can force a rebrand.
• Wasted branding. Signs, wraps, a domain, and a website built on a conflicting name may have to be redone.
• Listing disruption. Renaming a Google Business Profile, or starting a new one, can cost you visibility while things settle.
• Lost chance to register. If you later want your own federal registration, a close existing mark can block it.

Who this applies to

Every business choosing a name, and anyone naming a product or program. The risk is highest if you sell online, plan to grow into other states, or use a creative, distinctive name.

How to do it

1. Go to the USPTO website and open its trademark search system. Searching is free.
2. Search your exact name.
3. Search the main word on its own, plus spelling variations, sound-alikes, and plural forms.
4. Read the goods and services listed for each result. Note any that are related to what you sell.
5. Check the status. Note live marks. Don’t ignore dead ones. Search the web to see if they’re still in use.
6. Search your state’s trademark records if your state keeps them, usually through the Secretary of State.
7. Search the web, maps, and social platforms for unregistered use (see 8.3.2 Common-Law Trademark Use).
8. Save dated screenshots of everything.
9. If you find close matches, or the name matters a lot to your plans, hire a trademark attorney for a clearance search and opinion.

The USPTO also offers free help through its Trademark Assistance Center, Patent and Trademark Resource Centers, and searching webinars. These can teach you to use the tools, but they can’t give legal advice.

What proof to keep

• Dated screenshots of each USPTO and state search
• A list of close matches with their status and goods or services
• Any attorney clearance report or opinion letter

Store these with your brand and legal records.

Common mistakes

• Searching only the exact name. Similar marks can still conflict.
• Ignoring results in a different class. Related goods and services can conflict across classes.
• Assuming dead means free. The owner may still use the name and have common-law rights.
• Thinking the state accepted my LLC, so I’m fine. State entity approval and trademark rights are separate.
• Skipping the attorney for a big investment. If you’ll spend thousands on a brand, a clearance search is cheap insurance.

When to get help from a pro

The outline calls for professional clearance when a name is important, distinctive, national, or likely to be disputed (8.3.5). Talk to a trademark attorney if any of those apply, or if your search turned up close matches. The USPTO notes law school clinics may offer free or low-cost help. Ask:

• Based on a full clearance search, how risky is this name for my goods or services?
• Should I apply for federal registration, and what classes should I cover?
• What should I do about the close matches you found?

Questions people ask

Is the USPTO trademark search free? Yes. You can search the federal database at no cost. Filing an application costs money.

What counts as a similar trademark? Marks that look alike, sound alike, mean the same thing, or give a similar overall impression, used for related goods or services.

Do I need to search state trademarks too? It’s a good idea. Federal records don’t show every state registration or unregistered use. Check your state’s records and the web.

When should I hire a trademark attorney? When the name is central to your business, distinctive, used across states, or likely to be disputed, or when your own search turns up close matches.

Can I use a name if the trademark is dead? Maybe not. The USPTO warns that owners of dead marks may still use them and have common-law rights. Check whether it’s still in use.

Audit check

• Question: Was the business name searched in federal and state trademark records, with professional clearance where the name is important or risky?
• Pass looks like: Dated USPTO and state search records covering variations and related goods or services, no unresolved close matches, and an attorney clearance for any important or national name.
• Fail looks like: No trademark search. Only the exact name searched. Close matches ignored. A national brand launched without professional clearance.
• Evidence to collect: Search screenshots, the close-match list, and any attorney report.
