When Burger King Corporation sued Burger King restaurant in Mattoon, the small restaurant successfully defended its trademark through prior use within its local territory. The case — Burger King of Florida, Inc. v. Hoots — became a textbook example of geographic trademark rights.
Trademark infringement defenses must fit specific legal categories recognized by U.S. courts: fair use, prior use, abandonment, genericide, or no likelihood of confusion. Each requires concrete evidence, not just good intentions.
In defending against trademark claims, the burden of proof lies with the plaintiff to show that the infringement occurred. The defendant can then counter with evidence supporting their chosen defense — whether it’s showing the marks aren’t actually confusing to consumers or proving they used the mark first.
What are Trademark Infringement Defenses?
Trademark infringement defenses are legal arguments specifically designed to counter claims that you’ve violated another brand’s registered trademark.
Several defenses are available under trademark law. You might show that you used your mark first, prove your use is fair and reasonable, or demonstrate that customers wouldn’t confuse your brand with theirs. Each defense requires solid evidence, such as documentation of when you started using your mark or proof that your terms are common in your industry.
The key is selecting the appropriate defense and supporting it properly. Courts understand that not every similarity between brands is actual infringement, which is why these defenses exist. With proper documentation and the right legal argument, any business can effectively fight back against trademark infringement claims.
Common Defenses Against Trademark Infringement
Let’s look closely at some of those defenses we mentioned earlier. When someone claims trademark infringement, these are the tried-and-true arguments that can help protect your business.
- Fair Use
Sometimes, you can’t avoid using someone else’s trademark, and that’s perfectly fine. Think about a car mechanic specializing in BMW repairs; they need to use “BMW” to tell customers what they do. You’re generally in the clear as long as you use the trademark to describe or identify products accurately.
This protection extends beyond just product descriptions. Reviews, news articles, and even competitors can reference trademarked terms when making honest comparisons or sharing information. The key is being truthful and not suggesting any official connection or endorsement that doesn’t exist.
- Parody
Creating a playful twist on a famous brand to make a point or crack a joke often gets legal protection. Your parody must be obvious enough that people get the joke and don’t think you’re trying to be the authentic brand.
Las Vegas dog toy brand Chewy Vuiton successfully defended itself against claims of trademark infringement from fashion house Louis Vuitton with this argument, as judges agreed Chewy Vuiton is “[an] amusing parody” that “pokes fun at the elegance and expensiveness of a Louis Vuiton handbag.” Everyone knows it’s not Louis Vuitton, and that’s precisely the point.
Remember, though, successful parody isn’t just about being funny. It needs to say something about the original brand. You’re not just borrowing their fame; you’re commenting on it, criticizing it, or using it to make a broader point. Courts generally protect this creative expression, even if the trademark owner isn’t laughing.
- Non-Infringement
Sometimes, the simplest defense is showing that you’re not doing anything wrong. Maybe your mark looks similar, but you’re in a different industry. Perhaps you can prove that no one’s getting confused between the two brands. Real-world evidence of zero customer confusion can be your strongest ally here.
This defense often comes down to practical evidence and market realities. You should show that your target customers are sophisticated buyers who aren’t easily confused or that both brands have coexisted peacefully in the marketplace for years without any actual confusion. Customer surveys and expert testimony can strengthen this type of defense.
Other Defenses Against Trademark Infringement
Beyond the common defenses we just covered, there’s another set of powerful arguments that might help your case. These may be more technical, but they’ve saved many businesses from trademark troubles when the usual defenses don’t quite fit.
- Contesting Registration
Here’s where you challenge whether the trademark owner should have rights to the mark in the first place. Maybe they weren’t the first to use it, or perhaps the mark is too generic to deserve protection — like trying to trademark “smartphone” for electronic devices.
This defense often involves digging into the history of how the trademark was registered and used. You might find that the owner made false statements in their application, abandoned the mark at some point, or never actually used it in commerce. It’s like being accused of trespassing and then discovering the person who accused you doesn’t own the property.
- Doctrine of Laches
If a trademark owner has known about your use of a similar mark for years but never bothered to do anything about it, they might have waited too long to complain.
The court basically asks why the trademark owner waited so long to bring it up. If they sat on their rights while you built your brand and invested money in your business, they might be out of luck.
It’s similar to letting your neighbor build a fence slightly over your property line. If you wait years to complain, the court might not be sympathetic.
- Estoppel
This defense is all about broken promises and mixed signals. Maybe the trademark owner told you it was okay to use the mark, either through words or actions. Or they even helped you set up your business using the mark.
Later, if they try to claim infringement, you can point to their earlier behavior as evidence that they approved your use. The law doesn’t look kindly on people who say one thing and do another.
It’s like lending someone your car regularly for years, then suddenly accusing them of stealing it. The court will likely consider your past permission when making a decision. This defense often comes up in situations involving former business partners or franchise relationships that have gone sour.
Wrapping Up
Defending against trademark infringement is about knowing which defense fits your situation best. While some cases might be resolved with a straightforward fair use defense, others might require digging deep into registration records or documenting years of implied permission. The key is understanding your options and choosing the strategy that best matches your circumstances.
Remember, these defenses work best when you spot potential trademark issues early and address them head-on. Waiting until you receive a cease-and-desist letter usually means you’ll have fewer options and higher costs. That’s why smart business owners do their homework before launching new brands or products.

Frequently Asked Questions
What is an example of fair use in trademark cases?
A repair shop advertising “We fix Apple computers” is a classic example of trademark fair use. The shop needs to use Apple’s trademark to describe its services accurately, and as long as they don’t suggest they’re officially affiliated with Apple, this use is protected.
This type of descriptive fair use allows businesses to reference trademarked terms when necessary to explain their products or services.
Can I use a trademark without permission?
You can use someone else’s trademark without permission in specific situations, such as comparative advertising, news reporting, criticism, or commentary. For example, car dealers can compare their vehicles to competing brands, and movie reviewers can use film studio names when writing reviews.
However, you can’t use trademarks in ways that confuse consumers about the source or sponsorship of goods or services.
How do courts decide if a defense is valid?
Courts typically examine several factors, including whether consumers are likely to be confused and if the trademark use is commercially necessary or justified.
They look at real-world evidence like consumer surveys, market conditions, and the defendant’s intent in using the mark. The strength of the original trademark and the similarity between the two uses also play crucial roles in the court’s decision.
