Can  you trademark a business name that someone else is already using for different goods/services?

The short answer is yes, you can often trademark a business name that someone else is already using—provided that other business operates in a different industry or sells unrelated goods and services. You may be able to protect the same trademark for different goods/services.

However, the answer is not always straightforward, and there are important nuances to understand before investing time and money in a trademark application.

The Central Question: Likelihood of Confusion

Trademark law in the United States is not about giving someone absolute ownership over a word or phrase. Instead, it grants exclusive rights to use a mark only in connection with specific goods or services. The fundamental test under Section 2(d) of the Lanham Act is whether consumers would be confused about the source, sponsorship, or affiliation of the goods or services bearing similar marks.

The USPTO evaluates several factors to determine likelihood of confusion, but the most critical are:

• Similarity of the marks in appearance, sound, meaning, and overall commercial impression

• Relatedness of the goods or services—whether consumers would think they come from the same source

• Similarity of trade channels—whether the products are sold through the same types of stores or platforms

• Strength of the existing mark—how distinctive or famous it is

• Consumer sophistication—whether purchasers are likely to exercise care

If your name is identical to another business name but you operate in a completely different industry with no overlap in trade channels, confusion is unlikely, and both marks can often coexist peacefully.

How Trademark Classes Work

The USPTO organizes goods and services into 45 International Classes—34 for goods and 11 for services. When you apply to register a trademark, you must list the specific classes that cover your products or services. Importantly, a name used in one class does not automatically prevent registration in another class if the goods or services are unrelated.

For example, two businesses can both use the name "DOVE" without conflict—one for soap (Class 3) and one for chocolate (Class 30)—because consumers are not likely to assume that a personal care product and a confectionary item come from the same company.

The TTAB has also allowed identical marks to coexist in cases like "NOMAD" for barbecue grills versus "NOMAD" for cell phone accessories, finding that the goods were so disparate that confusion was not likely to occur.

Similarly, the "GIVN" trademark was permitted for bottled water despite an existing registration for cosmetics and online retail store services because the goods and trade channels did not overlap.

When Do Different Industries Still Create Problems?

While different industries generally allow coexistence, there are situations where even unrelated products can trigger a likelihood of confusion refusal.

The "Identical Marks" Principle

When trademarks are identical or nearly identical, the USPTO requires less similarity between the goods or services to find a likelihood of confusion. This means that even if your industry seems different, an identical name may still be blocked if consumers could reasonably believe both products come from the same company.

Overlapping Trade Channels

If both products are sold through the same types of retailers or online platforms, confusion becomes more likely. For example, a beverage company and a cosmetics company might both sell through Amazon, but the USPTO will examine whether the specific channels of trade overlap in a way that would confuse consumers.

The Expanding Definition of "Related" Goods

The USPTO has increasingly taken expansive views of what goods and services are considered related, often using third-party registrations and internet evidence to show that consumers are accustomed to seeing certain products offered by the same source. For instance, a company that sells clothing might also sell accessories, so a name used for shirts could block the same name for hats.

The Geographic Limitation of Common Law Rights

If the business already using the name does not have a federal trademark registration, its rights may be limited to its specific geographic area. Common law trademark rights arise from actual use in commerce, but they apply only in the region where the business actually operates and has established recognition.

A local coffee shop in Boulder using a name without federal registration cannot prevent you from using the same name in Austin, Texas, as long as you are not trading in overlapping markets. However, this geographic limitation does not apply if the prior user has obtained federal registration, which creates nationwide priority dating back to the filing date.

The Danger of Famous Marks

If the existing trademark is famous or well-known, it enjoys broader protection under federal dilution laws. Famous marks like Apple, Nike, or Coca-Cola can prevent others from using similar names even for completely unrelated goods and services if the use would "dilute" the distinctiveness of the famous mark. This is because the law recognizes that famous marks have built up such enormous goodwill that any unauthorized use, even in different industries, could weaken the mark's unique association with its owner.

Practical Steps Before Filing

Conduct a Comprehensive Trademark Search

Before applying to register a name, you should conduct a thorough search of both federal registrations and common law uses. A proper search should include:

• USPTO federal database for registered and pending marks

• Common law sources such as business directories, online searches, and industry publications

• State trademark databases

Assess the Relatedness of Goods or Services

Ask yourself honestly: Would a reasonable consumer think that your product and the existing business's product come from the same company? If the answer is no, you have a strong argument for registration.

Evaluate the Strength of the Existing Mark

Is the existing name fanciful (like "Kodak"), arbitrary (like "Apple" for computers), suggestive (like "Netflix"), or merely descriptive (like "Best Burger")? Stronger marks enjoy broader protection, while weaker, descriptive marks are entitled to narrower protection.

Consult a Trademark Attorney

Trademark law involves nuanced factual determinations. An attorney can assess the likelihood of confusion, evaluate the prior user's common law rights, and develop a filing strategy tailored to your situation.

Coexistence Agreements

If you discover that a business in a different industry is using the same name, but there is some risk of confusion, you may be able to negotiate a coexistence agreement with the other business. A coexistence agreement is a contract that allows both parties to use similar or identical trademarks by setting rules that limit the expansion and use of their marks to certain geographic territories or certain types of goods or services.

Coexistence agreements can be an easier and cheaper solution than litigation and can provide legal certainty for brand use or expansion. However, they require careful drafting to avoid future conflicts, and not all prior trademark owners will agree to enter into one.

What If the Prior User Has a Federal Registration?

If the business already using the name has a federal trademark registration, the analysis becomes more challenging. Federal registration gives the owner a legal presumption of nationwide rights, and the USPTO will typically refuse your application if the marks are similar and the goods or services are even somewhat related. You may still be able to register if you can demonstrate that the goods or services are completely unrelated and that consumers are not likely to be confused, but you face an uphill battle.

The Role of Honest Concurrent Use

If both parties have been using similar marks in different geographic regions without knowledge of each other, and confusion has not occurred, the USPTO may permit concurrent registrations. This is a narrow exception, but it exists to protect businesses that have established goodwill in good faith without awareness of a prior user.

Conclusion

Yes, you can trademark a business name that is already in use by someone else—but it depends entirely on the industry and the likelihood of consumer confusion.

If your products or services are completely unrelated to the existing user's goods or services, and the existing mark is not famous, you have a strong chance of obtaining federal registration. However, if there is any overlap in trade channels, consumer base, or product categories, you may face refusal or litigation.

The safest approach is to conduct a thorough trademark search before investing significant resources in a brand name. If a conflict exists, early consultation with a trademark attorney can help you assess your options, negotiate a coexistence agreement, or develop an alternative branding strategy before costly disputes arise.
