How to Check a Brand Name Before You Commit

The cheapest time to find a problem with a name is before you print it on anything. A few hours of checking can save you a rebrand, a demand letter or a refused trademark application. This is the order to do it in, from the broadest search to the narrowest, with notes on what each result means.

This is general information, not legal advice.

Step 1: Search federal trademark records

Start with the USPTO's Trademark Search system, which covers federally registered and applied-for marks. The USPTO's page on why to search for similar trademarks says one of the most common reasons applications are rejected is that the mark is too similar to one already registered, so this step matters even if you never plan to file.

Searching well means searching wider than your exact name. The USPTO's federal searching tips recommend:

• Alternative spellings and pronunciations. Look for marks that sound like yours even when they are spelled differently.
• Related goods and services, not just identical ones. Goods or services only need to be related in some way for confusion to be a problem.
• Take care with class filters. If the results are overwhelming, narrow them by coordinated class. Avoid narrowing by international class, because you will miss marks used on related goods that sit in a different class.

Make a list of variants before you start: the exact name, plural and singular forms, the name with and without spaces, phonetic spellings, and any word in the name on its own.

How to read what you find

The same tips page notes that only live applications and registrations can prevent your mark from being registered, so separate live records from dead ones. Then sort what is left:

• Same or similar name, related goods or services. This is the serious case. Treat it as a stop sign until a professional says otherwise.
• Same or similar name, clearly unrelated goods. Usually lower risk, but note it, especially if the other mark is well known.
• Only dead records. A good sign for registration, though a dead record can hide a business that is still trading without one.

Step 2: Check state registrations

A clean federal search is not a clean search. The USPTO's search guidance is explicit that its examining attorneys only check the federal database, and that searching state trademark databases and the internet is the applicant's responsibility.

Each state keeps its own trademark register, and the USPTO explains on its page about why to register a trademark that a state registration creates rights in that state only. Search the registers of the states where you will operate first, then the states where your closest competitors are based. State business entity databases are worth a look too: a company name on file is not a trademark, but it is evidence someone may be using the name.

Step 3: Look for unregistered use

Trademark rights in the US do not start with registration. The same USPTO page explains that common law rights come from using a mark in commerce within a particular geographic area, and that those rights may be enforceable only in the areas where the mark is used. A business that never registered can still hold rights in its own territory that came before yours.

Unregistered use does not show up in any database, so you have to go looking:

• Web searches for the name alone, and for the name plus your product category.
• App stores, online marketplaces and large retail sites.
• Map listings and local business directories in your target markets.
• Crowdfunding platforms, podcast directories and code repositories if they fit your field.
• The same searches for your phonetic variants.

Record who is using what, where, and for which products. A tiny business three states away selling something unrelated is a different risk from a similar name in your own category and city.

Step 4: Check domains

A domain and a trademark are separate things, and owning one does nothing to clear the other. Still, you need an address that matches the name.

ICANN's Lookup tool shows the current registration data for a domain name, pulled from the registry and registrar. If the domain is registered, visit it:

• An active business using the name is also evidence for Step 3.
• A parked page or a sale notice means you may be able to buy it, at a price the owner sets.
• Nothing at all does not mean abandoned; the owner may simply not be using it yet.

Check the likely variants as well: the plural, the common misspelling and the hyphenated form. People who mistype your name will land on whoever owns those.

Step 5: Check social handles

Search each platform you actually plan to use, not every platform that exists. For each one, note whether the exact handle is free, whether the account holding it is active, and what it posts. Do not plan around getting a taken handle released because the account looks dormant; assume you will need a variant, and decide on a single variant pattern you can use everywhere so customers can guess it.

Once you decide on the name, claim the handles the same day. Most cost nothing to hold and are easy to lose.

Step 6: Check the name in other languages

A name that is harmless in English can be rude, silly or unfortunate elsewhere. This check does not need a big budget:

• Ask native speakers of the languages spoken in your markets, and in large communities within them, what the name sounds like and whether it resembles any word.
• Say it out loud in different accents. Sounds shift, and a pleasant name can become an awkward one.
• Check slang, not just dictionary meanings. Slang moves fast and is where most surprises hide.
• Look at initials and abbreviations your customers might use, and at how the name reads when split differently.

If you plan to sell outside the US under the same name, do this before you file anything, because changing a name after launching in several countries costs far more than changing it now.

When to hire a trademark attorney

You do not need an attorney to run the searches above, but there are points where one is worth the fee. The USPTO's page on hiring a US-licensed attorney makes several points worth knowing:

• Applicants domiciled outside the US must be represented by a US-licensed attorney.
• USPTO employees can explain the process but cannot give legal advice.
• A private attorney can run a comprehensive clearance search across federal, state and common law sources, prepare the application and respond to office actions.
• Free or low-cost help exists, including the USPTO's Law School Clinic Certification Program, where law students work under faculty supervision.
• A legitimate attorney has their own USPTO.gov account; one who asks for your password is a warning sign.

Good moments to bring one in: when your own search turns up a similar live mark for related goods, before you spend real money on packaging, signage or advertising, before expanding into other countries, and immediately if you receive a demand letter.

Keep a record

Save screenshots of every search with the date, the exact terms and the results. The record helps an attorney pick up where you left off, and it documents what you found and when. Then set a reminder to repeat the federal search before you file and again before any major launch, because new applications are filed all the time.
