You can use a trademarked name without the owner’s permission in more situations than most people think, as long as your use won’t confuse consumers about who makes, sells, or endorses a product. Federal trademark law exists to prevent that confusion, not to lock a word or logo away from all other uses. Descriptive use, comparative advertising, reselling genuine products, news reporting, criticism, and clearly signaled parody are all generally allowed. What isn’t allowed is using someone else’s brand in a way that makes people think your goods come from them, or that they’ve blessed what you’re doing.
The Rule That Decides Every Case
Under the Lanham Act, using a copy or imitation of a registered mark in commerce is infringement when it’s likely to cause confusion, mistake, or deception.1Office of the Law Revision Counsel. 15 US Code 1114 – Remedies; Infringement; Innocent Infringement by Printers and Publishers Nobody has to prove real people were confused. It’s enough that confusion is probable.
Courts weigh several factors to answer that question: how similar the two marks look and sound, whether the goods or services overlap, whether the businesses share marketing channels, how carefully consumers shop in that market, and whether there’s evidence anyone has actually been confused. No single factor wins the case.
One threshold matters before any of that. Infringement only reaches commercial use. If you aren’t selling, distributing, or advertising something in connection with the mark, the infringement framework doesn’t apply to you. That’s why personal, editorial, and educational references to brand names sit outside the fight almost automatically.
When You Can Use a Trademarked Name Without Asking
Several established doctrines give you room to use someone else’s mark. The common thread runs through all of them: your use can’t suggest the trademark owner sponsors, endorses, or is affiliated with what you’re doing.
Describing Your Own Product
If a trademarked term also has an ordinary descriptive meaning, you can use it in that descriptive sense. “Apple” is a trademarked name for a technology company, but a grocery store obviously uses the word for fruit. A skincare company calling its product “honey-sweet” is describing a scent, not borrowing anyone’s brand. The test is whether you’re using the word to label your goods’ characteristics rather than as a source identifier.
Identifying the Trademark Owner’s Product
Sometimes you can’t refer to a product without naming it. A repair shop that fixes iPhones needs to say “iPhone.” A seller of replacement cartridges needs to name the printer they fit. This is called nominative fair use, and it works when three conditions are met: the product isn’t easily identifiable without the mark, you use only as much of the mark as necessary, and your use doesn’t imply sponsorship or endorsement.
Comparative advertising runs on the same principle. You can name a competitor’s product to make factual comparisons — “our battery lasts twice as long as Brand X” — provided your claims are accurate and you’re not suggesting the competitor stands behind your pitch. Stick to verifiable facts, and make it clear who’s doing the comparing.
Reselling Genuine Products
The first sale doctrine lets you resell authentic trademarked products without permission. Once the trademark owner authorizes the initial sale, their control over that specific item is exhausted. Consignment shops, used car lots, and online resale marketplaces all depend on this.
The doctrine has limits. You can use the trademark to identify what you’re selling, but you can’t plaster the brand across promotional materials in a way that suggests you’re an authorized dealer. First sale protection also breaks down in a few situations:
- The goods are materially different from what the trademark owner sold: altered serial numbers, removed warranty cards, expired products, or repackaged goods without clear disclosure.
- The products came through unauthorized channels, such as stolen goods or gray-market goods diverted from foreign markets without permission.
- Your marketing creates a false impression of a special relationship with the brand.
Reselling legitimate products in their original condition, with clear signaling that you’re an independent seller, is generally safe.
News, Commentary, and Teaching
Journalists use trademarks constantly. A news outlet covering a recall names the brand. Reviewers name what they’re reviewing. Professors reference real companies in class. None of this needs permission because it isn’t commercial use in the trademark sense and it serves the public. The only boundary is the familiar one: don’t imply the brand endorses the coverage.
Parody and Creative Work
Parodies of trademarks can be legally protected when they clearly signal that they’re poking fun rather than pretending to be the real thing. A joke product that plays on a famous brand is safer when consumers immediately recognize the humor and wouldn’t actually think the trademark owner made it. If the parody is subtle enough that people might mistake it for genuine merchandise, the protection thins out fast.
Creative works like books, movies, songs, and video games get some breathing room when they reference a trademark for artistic reasons rather than as their own brand identifier. Referencing a real brand inside a story is different from stamping someone else’s logo on merchandise you sell.
An Extra Layer for Famous Brands
Household-name brands get protection beyond confusion. Federal law lets owners of truly famous marks stop uses that weaken or tarnish their brand even when the products are completely unrelated and no one would be confused.2Office of the Law Revision Counsel. 15 US Code 1125 – False Designations of Origin, False Descriptions, and Dilution
This comes in two forms. Blurring happens when a famous mark gets used on unrelated products so widely that its association with its original source erodes. Tarnishment happens when a famous mark gets linked to something offensive, low-quality, or disreputable that damages the brand’s image.2Office of the Law Revision Counsel. 15 US Code 1125 – False Designations of Origin, False Descriptions, and Dilution
Dilution claims aren’t available to every registered trademark. The mark has to be recognized by the general consuming public across the country. But if you’re playing with a household name, the “no confusion, no problem” logic doesn’t fully protect you.
Domain Names and Hashtags
Registering a domain name that matches someone else’s trademark with intent to profit from it — usually by selling it back to the brand — is cybersquatting. Federal law targets this directly and lets courts transfer or cancel the domain and award attorney fees.3Office of the Law Revision Counsel. 15 USC Chapter 107, Subchapter II – Cybersquatting Protection There’s also a faster administrative route through ICANN, where a trademark owner can win transfer of a domain by showing it’s identical or confusingly similar to their mark, the registrant has no legitimate interest, and the registration was in bad faith.4ICANN. Uniform Domain-Name Dispute-Resolution Policy
Hashtags are a gray area. Some courts have found that hashtagging a competitor’s name could deceive consumers and support an infringement claim; others have treated hashtags as descriptive tools that don’t function as trademarks. Context drives the outcome. Using #BrandName to review or discuss an actual brand is a different situation than using it to pull that brand’s customers toward your competing product.
What Infringement Actually Costs
Trademark enforcement usually opens with a cease-and-desist letter demanding you stop. Many disputes end there. Ignoring the letter tends to move things into federal court, where the exposure gets serious.
Courts can order injunctions forcing you to stop using the mark, and in counterfeiting cases can authorize seizure of infringing goods and the equipment used to make them.5Office of the Law Revision Counsel. 15 US Code 1116 – Injunctive Relief The trademark owner can also recover actual damages and any profits you earned from the infringement. When the infringement was deliberate, courts can increase that award up to three times the damages or profits.6Office of the Law Revision Counsel. 15 US Code 1117 – Recovery for Violation of Rights
Counterfeiting carries the steepest numbers. Instead of proving actual damages, the trademark owner can elect statutory damages ranging from $1,000 to $200,000 per counterfeit mark per type of product sold. Willful counterfeiting pushes the ceiling to $2,000,000 per mark per product type. Attorney fees can be awarded in exceptional cases, and trademark litigation isn’t cheap on either side.6Office of the Law Revision Counsel. 15 US Code 1117 – Recovery for Violation of Rights
Checking Whether a Name Is Trademarked
Before using a name, logo, or slogan that might belong to someone else, run it through the USPTO’s Trademark Search system, a free online database of all federally registered and pending marks.7United States Patent and Trademark Office. Search Our Trademark Database You can search by word, design code, or owner name.
Two caveats. First, a clean search isn’t a green light. Common law trademark rights exist without registration, so a business can hold enforceable rights in a name that never appears in the USPTO database. State trademark databases and general web searches for the name in use help close that gap. Second, registrations can lapse. Federal registrations require maintenance filings between the fifth and sixth years after registration, and renewal filings every ten years after that, with a six-month grace period after each deadline before cancellation.8United States Patent and Trademark Office. Keeping Your Registration Alive A mark showing as registered may have been abandoned if the owner missed those filings.
When Your Use Doesn’t Fit an Exception: Licensing
If your planned use doesn’t fit any permitted category, the direct path is a license. A trademark license is a contract giving you permission to use the mark on specific terms: what products or services it covers, where you can sell, how long the permission runs, and what you pay, usually a royalty or flat fee.
One provision catches licensees off guard. Trademark owners are legally required to maintain quality control over how their mark is used. A license that skips oversight — a “naked license” — can backfire on the owner by giving competitors grounds to argue the mark has been abandoned. Legitimate license agreements will include product standards, approval processes for marketing materials, and sometimes inspection rights. Those aren’t formalities; they protect the value of the mark for everyone involved.
To pursue a license, contact the trademark owner’s legal or brand licensing department directly. Many companies publish a licensing page outlining their process. For federally registered marks, the USPTO database identifies the current owner and often provides contact information.
