If you are asking, “Can two businesses use the same trademark?” You are not alone. Many entrepreneurs, startups, and established businesses wonder whether using the same brand name as another company is legally possible, especially when the businesses operate in different industries. The answer depends on trademark law, the relationship between the goods or services, and whether consumers are likely to be confused. Understanding these factors before filing a trademark application can help reduce legal risks and avoid costly disputes later. One of the most common questions business owners ask before filing a trademark application is

“Can two companies have the same trademark?”

The answer is yes, but only in certain situations.

Many entrepreneurs assume that once a trademark is registered, no one else can ever use the same name. Others believe that simply operating in a different industry automatically allows them to register an identical trademark. In reality, U.S. trademark law is far more nuanced. Whether two businesses can legally use the same trademark depends on several factors, including the relationship between their goods or services, how consumers encounter the brands, and whether there is a likelihood of confusion in the marketplace.

For example, two businesses may be able to use the same trademark if they operate in completely unrelated industries and consumers are unlikely to believe the companies are connected. On the other hand, businesses in different industries may still face trademark conflicts if their products, services, or customer base overlap in ways that could create confusion.

This is why selecting a brand name involves much more than searching the USPTO database. A thorough trademark strategy considers not only existing registrations but also common law rights, future business expansion, related markets, and the overall strength of the proposed trademark.

At Adams Law Office, we help businesses throughout Berkeley, the San Francisco Bay Area, and across California evaluate potential trademarks before they become costly legal disputes. Through our Trademark Services, we assist clients with comprehensive trademark clearance searches, federal trademark applications, Office Action responses, and long-term brand protection strategies.

If you are still exploring how trademark registrations are organized, our guide to Understanding the 45 Trademark Classes: A Complete Guide for Businesses provides a helpful foundation before choosing a brand name.

In this guide, we will explain when businesses can legally share the same trademark, why different industries do not always eliminate trademark conflicts, how the USPTO evaluates trademark likelihood of confusion, and the practical steps you can take to reduce legal risk before investing in your brand.

Why Trademark Classes Alone Do Not Decide the Outcome

One of the biggest misconceptions about trademarks is that registering in a different trademark class automatically avoids conflicts. While trademark classes are an important part of the application process, they do not determine whether a trademark can be registered or coexist with another mark.

The USPTO organizes goods and services into 45 trademark classes to help categorize applications. These classes make it easier to identify what a trademark covers, but they are primarily an administrative tool. They are not a guarantee that two businesses can use the same trademark simply because they fall into different classes.

Instead, examining attorneys look at the relationship between the goods and services. If consumers are likely to believe that the products or services come from the same company, a trademark conflict may still exist, even when the applications are filed in different classes.

For example:

• A company selling athletic apparel (Class 025) and another selling athletic bags (Class 018) will file under different classes, but consumers often expect those products to come from the same brand.
• A business offering downloadable software (Class 009) and another providing software as a service (SaaS) (Class 042) operate in different trademark classes, yet the services are closely related in the minds of consumers.
• A medicated skincare brand (Class 005) and a cosmetics company (Class 003) may also face trademark issues because their products are commonly marketed together through similar retail channels.

On the other hand, businesses offering completely unrelated products or services may be able to use the same trademark without creating consumer confusion. Every situation depends on the specific facts rather than the trademark class alone.

If you are unfamiliar with how the USPTO categorizes goods and services, our guide on Understanding the 45 Trademark Classes: A Complete Guide for Businesses explains how the classification system works and why selecting the correct class is an important part of the application process.

The takeaway is simple: different trademark classes do not automatically mean different trademark rights. The USPTO focuses on whether the goods or services are commercially related and whether consumers are likely to assume they originate from the same source.

This brings us to one of the most important concepts in U.S. trademark law: likelihood of confusion. Understanding how the USPTO evaluates this standard helps explain why some trademarks are approved while others are refused, even when they appear to operate in different industries.

What Is Trademark Likelihood of Confusion?

When deciding whether two businesses can use the same trademark, the USPTO does not simply compare the names side by side. Instead, the central question is whether the average consumer is likely to be confused about the source of the goods or services.

This legal standard, known as trademark likelihood of confusion, is one of the most common reasons trademark applications are refused and one of the most frequent issues in trademark disputes.

Importantly, the USPTO does not require proof that customers have already been confused. The question is whether confusion is reasonably likely based on how consumers encounter the brands in the marketplace.

Factors the USPTO Considers

No single factor determines the outcome. Instead, examining attorneys evaluate the overall circumstances, including:

Similarity of the Trademarks

The USPTO looks at how the trademarks look, sound, and convey meaning. Marks do not have to be identical to create confusion. Similar spellings, pronunciations, or commercial impressions may lead consumers to believe the brands are related.

Relatedness of the Goods or Services

This is often the deciding factor when considering a same trademark/different industry situation. Even if two businesses technically operate in different industries, their products or services may still be considered commercially related.

For example, consumers may reasonably expect the same company to offer:

• Clothing and jewelry 
• Coffee shops and packaged coffee
• Mobile apps and cloud-based software
• Fitness equipment and online fitness coaching

Because these goods and services naturally complement one another, consumers may assume they originate from the same business.

To better understand how the USPTO evaluates this issue, see our guide on Section 2(d) Refusal: Relatedness of Goods and Services.

Trade Channels and Customers

The USPTO also considers where and how the products or services are sold.

Questions may include:

• Are they sold through the same websites or retail stores?
• Do they target the same customer demographic?
• Are they marketed using similar advertising channels?

Even businesses that describe themselves as operating in different industries may overlap significantly in their customer base.

Strength of the Earlier Trademark

A highly distinctive or arbitrary trademark generally receives broader legal protection than a weak or descriptive mark. Strong trademarks have a larger area of protection and are more likely to prevent later registrations that could cause consumer confusion, even if the goods or services are not identical.

Our article on What Makes a Strong Trademark? explains why inherently distinctive trademarks are often easier to protect.

Why This Matters

Many business owners focus on whether a trademark already exists without asking the more important question:

Will consumers believe that the same company provides both goods? That is the heart of a likelihood of confusion analysis.

In some cases, two businesses operating in different industries may successfully coexist because consumers would never assume they are related. In other cases, even seemingly different businesses may face trademark conflicts because their products, services, or future expansion plans overlap.

Understanding this distinction is essential before investing in branding, packaging, marketing, or a trademark application. A careful analysis today can help prevent expensive office actions, opposition proceedings, or legal disputes later.

The next section looks at real-world examples of businesses using the same trademark in different industries and explains why some coexist peacefully while others cannot.

Examples of When the Same Trademark May Be Allowed

One of the easiest ways to understand same trademark/different industry situations is by looking at how trademark law applies in the real world.

Contrary to popular belief, the USPTO does not prohibit every identical trademark. In some cases, identical trademarks used by different businesses can legally coexist because consumers are unlikely to believe the companies are related.

The key question remains the same:

Would an average consumer reasonably think these products or services come from the same source?

If the answer is no, the businesses may be able to coexist without creating trademark confusion.

Example 1: Completely Unrelated Industries

Imagine one company uses the trademark “Summit” for mountain climbing equipment, while another uses “Summit” for accounting software.

Although the trademarks are identical, the products serve completely different purposes, target different customers, and are marketed through different channels. Most consumers would not assume that a software company also manufactures climbing gear.

In situations like this, coexistence may be possible.

Example 2: Different Customers and Different Markets

Suppose a business sells industrial water treatment systems under a particular trademark, while another company uses the same trademark for children’s educational toys.

These businesses operate in unrelated markets, sell to different types of customers, and have little overlap in their purchasing channels. The likelihood of consumer confusion may be relatively low, making concurrent use more feasible.

Example 3: Famous Real-World Brands

There are well-known examples of similar or identical trademarks existing in different industries because consumers clearly understand they represent different businesses.

For instance:

• Delta is associated with both an airline and plumbing fixtures.
• Dove is recognized as both a personal care brand and a chocolate brand.

These examples illustrate an important principle: trademark rights are generally tied to the specific goods or services offered, not ownership of a word in every possible industry.

However, these examples should not be viewed as a blueprint for choosing an existing trademark. Each situation depends on its own facts, and famous brands often involve decades of legal history, coexistence agreements, or unique circumstances that may not apply to newer businesses.

Every Case Requires Individual Analysis

While some businesses can successfully operate with the same trademark in different industries, many others cannot. The analysis depends on factors such as

• Whether the goods or services are commercially related.
• Whether the businesses target similar customers.
• Whether consumers are likely to believe the companies are affiliated.
• Whether either business may reasonably expand into the other’s market.

This is why relying solely on a quick USPTO search can be risky. A trademark that appears available at first glance may still present significant legal concerns after a more comprehensive analysis.

Our guide on Trademark Clearance Searches Explained: Why One Search Is Often Not Enough explains why evaluating related businesses, common law rights, and marketplace conditions is just as important as reviewing federal registrations.

Just as two businesses in different industries can sometimes coexist, the opposite is also true: companies operating in seemingly separate markets may still face trademark conflicts. Understanding why this happens is essential before selecting or investing in a new brand name.

When Businesses in Different Industries Can Still Have Trademark Problems

Although two businesses may operate in different industries, that does not automatically mean they can safely use the same trademark. Modern businesses frequently expand into new markets, sell through the same online platforms, and serve overlapping customer bases. As a result, industries that once seemed unrelated are often much more connected than they appear.

This is why the USPTO focuses on consumer perception rather than industry labels alone. If consumers are likely to believe that two businesses are affiliated, sponsored by the same company, or offer products from a common source, a trademark conflict may still arise. The USPTO will also find a likelihood of confusion if it appears likely that a business selling products in one class will expand into another class.   

Business Expansion Can Change the Analysis

Many successful brands do not remain limited to a single product or service.

For example:

• A clothing company may later launch shoes, handbags, fragrances, or jewelry.
• A software developer may expand from downloadable applications to cloud-based SaaS platforms, consulting services, or AI tools.
• A restaurant may begin selling packaged foods, sauces, or branded merchandise in retail stores.
• A fitness brand may offer apparel, nutritional supplements, online coaching, and mobile applications under the same trademark.

Even if these offerings fall into different trademark classes, consumers may naturally expect them to come from the same business. This increases the likelihood of confusion and may prevent another company from registering or using a similar trademark.

The Rise of AI and Digital Businesses

The rapid growth of artificial intelligence has created new trademark challenges. Companies that originally operated in traditional industries are now launching AI-powered products, subscription platforms, mobile applications, and digital services.

As businesses diversify, trademark boundaries become less clear. A name that appears available today could create conflicts tomorrow if another business expands into a related market.

If you’re using AI to brainstorm names, our guide on The Hidden Trademark Risks of Using AI Brand Name Generators explains why AI-generated suggestions should always be evaluated through a comprehensive trademark clearance process before adoption.

Online Commerce Creates More Overlap

E-commerce has also blurred traditional industry lines. Consumers regularly encounter brands across websites, marketplaces, social media, and mobile apps, making it easier to assume that related products come from the same company.

For example, a consumer may expect a business that sells medicated skincare products to also offer cosmetics, wellness products, or beauty accessories under the same trademark. Similarly, a technology company may naturally expand into consulting, training, or software support services.

Because today’s brands often grow beyond their original markets, trademark disputes may involve businesses that initially believed they operated in completely different industries.

A Comprehensive Trademark Search Is More Important Than Ever

Choosing a brand name based solely on whether an identical trademark appears in the USPTO database can create unnecessary legal risk. An effective trademark clearance search evaluates much more than existing registrations. It also considers related industries, common law trademarks, online marketplace use, domain names, and the realistic potential for future expansion.

Our article on Do You Really Need a Common Law Trademark Search Before Filing? explains why experienced trademark attorneys often recommend going beyond a basic federal search before investing in a new brand.

In some situations, even when two businesses could potentially create confusion, there are legal mechanisms that allow both parties to continue using similar trademarks. One of the most common is a trademark coexistence agreement. 

What Is a Trademark Coexistence Agreement?

In some trademark disputes, the solution is not for one business to abandon its brand. Instead, the parties may decide to enter into a trademark coexistence agreement.

A trademark coexistence agreement is a legally binding contract between two trademark owners that establishes the conditions under which both businesses can continue using similar or even identical trademarks without creating unnecessary consumer confusion.

These agreements are not appropriate in every case, but they can be an effective solution when both parties believe coexistence is possible and the risk of confusion can be managed.

What Does a Trademark Coexistence Agreement Typically Include?

While every agreement is tailored to the specific situation, common provisions may address:

• The specific goods or services each business may offer.
• Geographic areas where each trademark may be used.
• Marketing and advertising limitations.
• Logo, branding, or packaging differences.
• Online usage, including websites and social media.
• Procedures for resolving future disputes if business activities change.

The goal is to reduce the likelihood that consumers will mistakenly believe the businesses are connected while allowing each party to continue building its brand.

Does a Coexistence Agreement Guarantee USPTO Approval?

Not necessarily.

Although the USPTO may consider a coexistence agreement as evidence that the parties believe confusion is unlikely, the examining attorney is not automatically required to approve a trademark application. The USPTO still has an independent responsibility to determine whether registration would likely confuse consumers.

This is why coexistence agreements should be carefully drafted and supported by a well-reasoned legal analysis rather than treated as a simple formality.

When Might a Coexistence Agreement Be Appropriate?

Depending on the circumstances, businesses may consider a coexistence agreement when:

• The trademarks are similar, but the goods or services are sufficiently different.
• The parties serve different customer groups or geographic markets.
• Both businesses have used their trademarks for an extended period without evidence of actual consumer confusion.
• A negotiated resolution is preferable to the cost and uncertainty of TTAB proceedings or litigation.

However, coexistence is generally not advisable where consumers are likely to believe the businesses are affiliated or where the agreement would create ongoing confusion in the marketplace.

Every Situation Requires a Careful Risk Assessment

A coexistence agreement can be a practical solution in the right circumstances, but it should never replace a thorough trademark analysis. Businesses should first evaluate the strength of their trademark rights, the relatedness of the goods or services, potential expansion plans, and the overall likelihood of confusion before deciding whether coexistence is appropriate.

Working through these issues early can often prevent costly disputes and provide greater certainty as a business grows.

The next step is understanding what business owners can do before choosing a brand name to minimize the risk of trademark conflicts. We’ll cover practical best practices that can save significant time, expense, and legal complications later.

Best Practices Before Choosing a Brand Name

Choosing a brand name is one of the earliest and most important decisions a business makes. Unfortunately, many entrepreneurs invest in logos, websites, product packaging, and marketing campaigns before determining whether they can legally use the name.

A proactive trademark strategy can significantly reduce the risk of receiving a USPTO refusal, facing a trademark dispute, or being forced to rebrand after launch.

Here are several best practices every business owner should follow before adopting a new trademark.

Conduct More Than a Basic USPTO Search

Searching the USPTO database is an important first step, but it is rarely enough.

A federal search may identify registered and pending applications, yet it does not reveal every trademark that could affect your rights. Businesses may also have common law trademark rights through use in commerce, even if they have never filed a federal application.

A comprehensive trademark clearance search typically reviews:

• Federal trademark registrations and applications
• State trademark registrations
• Common law business names
• Domain names
• Company names
• Social media platforms
• Online marketplaces and industry-specific uses

Our article on Trademark Clearance Searches Explained: Why One Search Is Often Not Enough explains why a thorough search provides a much clearer picture of potential legal risks.

Think Beyond Your Current Business

Many startups choose a trademark based only on their first product or service. However, successful businesses often expand into related markets over time.

Ask yourself:

• Will we introduce new products?
• Could we expand into software, consulting, or online services?
• Might we sell internationally?
• Could licensing become part of our business model?

Choosing a flexible trademark today may help avoid expensive branding changes in the future.

Select a Distinctive Trademark

The strongest trademarks are those that are unique and memorable rather than merely descriptive.

Fanciful, arbitrary, and suggestive trademarks are generally easier to register, enforce, and defend than names that simply describe the product or service.

If you are evaluating possible brand names, our guide on What Makes a Strong Trademark? explains why distinctiveness plays such an important role in trademark protection.

Consider Future Customer Perception

Instead of asking only whether another company already uses the name, ask a more practical question:

If customers encountered both brands, would they assume the businesses are related?

This perspective closely mirrors the USPTO’s likelihood of confusion analysis and can help identify potential issues before filing an application.

Work With an Experienced Trademark Attorney Early

A trademark attorney does far more than prepare paperwork.

Early legal guidance can help you:

• Evaluate potential trademark conflicts.
• Assess the likelihood of confusion.
• Recommend stronger brand names before filing.
• Conduct comprehensive clearance searches.
• Develop a filing strategy that supports future business growth.

Addressing these issues before investing in branding is often far less expensive than responding to an Office Action, defending a TTAB proceeding, or undertaking a complete rebrand after launch.

Whether you’re launching your first business or expanding an established brand, taking the time to evaluate your trademark carefully can help protect the investment you’re making in your company’s identity.

Why Working With a Trademark Attorney Can Help

Determining whether two businesses can use the same trademark in different industries is rarely as straightforward as comparing names in the USPTO database. Every trademark must be evaluated in the context of the goods or services offered, the target customers, marketplace conditions, and the potential for consumer confusion.

An experienced trademark attorney can help identify legal risks before they become expensive problems.

Frequently Asked Questions

Can two businesses legally use the same trademark?

Yes, they can, but only in certain situations. The key issue is whether consumers are likely to believe the two businesses are connected. If the goods or services are unrelated and there is little chance of consumer confusion, identical or similar trademarks may be able to coexist.

Can two companies have the same trademark in different industries?

Sometimes. Operating in a different industry does not automatically make a trademark available. The USPTO considers factors such as the relatedness of the goods or services, customer overlap, marketing channels, and the overall likelihood of confusion before deciding whether two businesses can use the same trademark.

Do different trademark classes prevent trademark conflicts?

No. Trademark classes help organize goods and services for administrative purposes, but they do not determine whether a trademark can be registered. Two businesses in different trademark classes may still face conflicts if consumers are likely to assume their products or services come from the same source.

What is the trademark likelihood of confusion?

Trademark likelihood of confusion is the legal standard used by the USPTO and courts to determine whether the average consumer is likely to be confused about the source of the goods or services. Factors such as the similarity of the trademarks, the relatedness of the goods or services, trade channels, and customer perception all play a role in this analysis.

Can two businesses use the same business name?

Possibly. A business name and a trademark are not the same thing. Two businesses may legally use similar or even identical business names in some circumstances, but trademark rights depend on how the name is used in commerce and whether it creates consumer confusion.

What is a trademark coexistence agreement?

A trademark coexistence agreement is a legal agreement between two businesses that establishes how similar or identical trademarks may be used without creating consumer confusion. These agreements often define permitted goods or services, geographic areas, branding requirements, and other conditions, but they do not automatically guarantee USPTO approval.

Can I register a trademark that already exists?

It depends. If the existing trademark covers unrelated goods or services and consumers are unlikely to believe the businesses are connected, registration may be possible. However, every situation requires a careful evaluation of the marketplace, prior trademark rights, and the likelihood of confusion before filing an application.

Should I perform a trademark search before choosing a brand name?

Absolutely. Conducting a comprehensive trademark clearance search before investing in branding can help identify potential conflicts with federal registrations, common law trademarks, business names, domain names, and online marketplace use. Addressing these issues early is often far less costly than responding to an Office Action or rebranding after launch.

Conclusion

Whether two businesses can use the same trademark in different industries depends on one critical question: Are consumers likely to be confused? The answer requires more than comparing trademark names or classes. It involves evaluating the relatedness of the goods or services, marketplace conditions, and the likelihood of confusion under trademark law.

Before investing in a new brand, conduct a comprehensive trademark clearance search and seek legal guidance to identify potential risks early. At Adams Law Office, we help businesses protect their brands through trademark searches, USPTO filings, Office Action responses, TTAB proceedings, and ongoing trademark protection.
