- Consulting a trademark attorney can help you assess your rights and navigate the trademark registration process.
If you're wondering, "can you trademark something that already exists," the simple answer is "no." Generally speaking, if somebody has used a trademark before you, you can't register the trademark for yourself. However, if you have been using the trademark yourself, it is entirely possible to register the trademark to prevent others from using it.
Can You File for a Trademark That Exists?
Registered trademarks offer certain legal protections to unique items such as logos or designs that are associated with tangible objects. In simple terms, this means if somebody else used a trademark before you, you're not able to register that trademark for yourself. If, however, you used the trademark first and learn that somebody else is using it, you may have grounds to contest their use of the trademark in question.
Keep in mind this only applies to the market where you were operating when the other entity registered the trademark. In cases like this, you have virtually no rights in terms of market expansion. The entity that registered the trademark with appropriate federal authorities takes priority in every other market, and they have the right to keep you from using the registered trademark in any areas where you weren't originally using it before they registered. When a company registers a trademark, they are providing a formal, legally binding notice that they own it and nobody else is authorized to use it.
The laws that pertain to trademarks are complicated. This is why many people choose to hire an attorney with specific knowledge and experience in this area if they need to contest a trademark. An existing product might be protected in multiple ways, such as:
- A patent
- A registered trademark
- A trade secret
Registering a trademark is only a single part of obtaining strong and enforceable trademark protection. In fact, registering a trademark isn't a legal requirement when it comes to asserting your ownership. Trademarks become stronger as they are used over a period of time. This fact causes many people to choose to use their trademarks before they register them. In this particular scenario, you can register an already existing trademark. The United States Patent Office has a specific registration form exactly for this purpose.
Understanding Common Law Trademark Rights
A name does not need to be registered with the United States Patent and Trademark Office (USPTO) to be legally protected. Businesses that use a name in commerce automatically acquire common law trademark rights. These rights typically apply only to the geographic area where the name is actively used. For instance, a local bakery using the name "Sweet Delights" may hold common law rights in its town, even if it has not registered the name federally.
Common law rights may prevent you from registering a trademark if your application could create confusion with an existing unregistered name in the same industry. Courts and the USPTO evaluate factors such as:
- The similarity of the names.
- The proximity of the goods or services.
- Evidence of consumer confusion.
- The distinctiveness of the existing name.
Before seeking to trademark a name that already exists, it is wise to perform a comprehensive trademark search to identify any common law users.
Geographic Limitations on Trademark Protection
Under common law, trademark rights are geographically limited. A business may only prevent others from using a similar name within its local market area. If a business operates under a name in one state without expanding, another company could register a federal trademark for the same name in a different region.
Federal registration provides nationwide protection, regardless of the geographic area where a business currently operates. If you wish to expand your business beyond your local area, securing a federal trademark can prevent others from using the same name in other states.
Registering Similar Trademarks
If somebody else is already using a mark that is reasonably similar to yours, it's likely that your application for trademark registration will be denied. United States trademark law requires trademarks to be entirely unique from any other than are currently in use. Changing the color of a trademark, for example, or making other minor alterations, is usually not sufficient to make a trademark unique enough to make it ok for you to use. This is true from both a legal and a morally ethical point of view.
However, if you can prove that you've used the trademark before it was registered by somebody else, it may be possible to register it for yourself. You'll need to be able to provide sufficient proof that you are the trademark's original owner to be successful.
Adding something to the original design that could be considered category changing might be enough to get you a patent. A ball-point pen that heats up when its ink is cold, for example, might qualify for this. While it's still a pen, a significant redesign has occurred.
The main thing to keep in mind when working with trademarks is the need to avoid confusing consumers. With this in mind, if it's highly unlikely that another company's customers will be confused if you use the same name they're using, there probably isn't a trademark issue in play.
One of the things the courts will use to determine how likely it is for consumers to be confused is considering whether or not the two companies in question are operating in the same industry. For example, if you were to start a brand new social media platform and name it "Facebook," you're likely not going to win a trademark dispute with Mark Zuckerberg.
However, if you named your new social media company "Hotspot," and a company that produces cookbooks is already using this name, you're not likely to run into a trademark issue. While both companies are using the same name, they are in completely different industries so the potential for creating confusion among consumers is practically nonexistent.
The Likelihood of Consumer Confusion
The most critical factor the USPTO considers when evaluating trademark applications is the likelihood of consumer confusion. A trademark application will likely be denied if the proposed name is too similar to an existing mark and may cause consumers to mistake one brand for another. Key elements considered include:
- Similarity of the Marks: Visual, phonetic, or conceptual similarities between two trademarks can lead to confusion.
- Relatedness of Goods or Services: If two businesses operate in the same industry or offer related products, the risk of confusion increases.
- Channels of Trade: Similar marks used in the same marketing channels or sold to similar customers are more likely to cause confusion.
- Actual Evidence of Confusion: Documented instances of customers confusing two businesses can be compelling evidence.
Applicants seeking to register a name that already exists in some form should assess whether their mark could be perceived as misleadingly similar.
Steps to Conduct a Trademark Search
Before attempting to trademark a name that already exists or is similar to another, conducting a thorough search is essential to minimize legal risks. The following steps can help identify potential conflicts:
- USPTO Trademark Database Search: Use the USPTO's Trademark Electronic Search System (TESS) to look for registered trademarks and pending applications.
- Common Law Search: Search business directories, social media platforms, Google, and state trademark databases for unregistered names in use.
- Domain Name Search: Check domain registries to see if the name is in use online.
- Industry-Specific Research: Examine trade publications, marketplaces, and competitor websites to identify similar names within your industry.
Conducting a professional trademark search or consulting a trademark attorney can help ensure no conflicts are overlooked.
What to Do If a Trademark Conflict Arises
If you discover that a name you wish to trademark is already in use, you have several options:
- Modify Your Brand Name: Consider altering the name to make it more distinctive and reduce the likelihood of confusion.
- Negotiate Coexistence: In some cases, businesses may agree to use similar names in non-competing markets, often formalized through a coexistence agreement.
- Challenge the Existing Use: If you believe you have priority rights due to prior use, you can challenge an existing registration through a cancellation proceeding or oppose a pending application.
- Rebrand: If the conflict is unavoidable, rebranding your business might be the safest long-term solution to avoid legal disputes.
Consulting an experienced trademark attorney can clarify your options and guide you through dispute resolution.
