Yes — you can use brand names in a book. Your character can drink Coca-Cola, drive a Ford, google a name, and scroll TikTok, and none of that is trademark infringement.
In this guide, you will learn:
- Why merely mentioning a brand is legal under nominative fair use
- The four legal risks that actually cause trouble for authors
- Seven habits that keep your manuscript out of a lawyer letter
- When to invent a fictional brand instead
Here is what the law actually says, and where the real line sits.
Disclaimer: This article is general information for writers, not legal advice. It does not create an attorney-client relationship. Trademark law varies by country and turns heavily on specific facts. If a brand is central to your plot, portrayed negatively, or in your title, consult an intellectual property attorney before you publish.
Can You Use Brand Names in a Book?
You can use brand names in a book. Referring to a real product by its real name is legal under a doctrine called nominative fair use, because you are using the name to identify the actual product rather than to sell your own competing goods. Trouble only starts when a mention becomes false, disparaging, or confusing about sponsorship.
That single sentence resolves the question for roughly 95% of the brand mentions in an average manuscript. Most authors worrying about this are worrying about the safest possible use.
The remaining 5% is worth understanding, because that is where actual cease-and-desist letters come from.
What Is Nominative Fair Use?
Nominative fair use — using someone else’s trademark to refer to the trademark owner’s own product, rather than to brand your own goods.
Trademark law exists to prevent consumer confusion about who made something. A trademark is a source identifier: it tells a shopper that this can of soda came from The Coca-Cola Company.
When your detective orders a Coke in a diner, no reader thinks Coca-Cola wrote or endorsed your novel. There is no confusion about source, so there is no infringement.
Courts in the Ninth Circuit apply a three-part test. The use qualifies as nominative fair use when the product cannot easily be identified without the mark, you use only as much of the mark as necessary, and you do nothing to suggest sponsorship or endorsement. You can read the doctrine’s development in the American Bar Association’s analysis of nominative trademark use.
Writing “she wiped the counter with a Clorox wipe” satisfies all three parts effortlessly. You named the product, used nothing but the word, and implied no partnership.
The Four Legal Risks That Actually Matter
Only four theories realistically threaten an author who mentions a brand. Knowing them by name tells you exactly what to avoid.
| Risk | What triggers it | How likely for novelists |
|---|---|---|
| Trademark infringement | Using a mark so readers think the brand made or sponsored your book | Very low |
| Dilution by blurring | Weakening a famous mark’s distinctiveness through unrelated use | Low |
| Dilution by tarnishment | Linking a famous mark to sordid, degrading, or unsavory content | Low but real |
| Defamation / trade libel | Stating false facts that damage a company or its product | Low but real |
1. Trademark Infringement
Infringement requires a likelihood of confusion about source. Mentioning a product inside a story almost never creates that.
The danger zone is the cover, the title, and the marketing — not the prose. A novel called The Starbucks Murders with a green siren on the cover invites the argument that shoppers think Starbucks published it.
2. Dilution by Blurring
Dilution protects famous marks only — think Nike, Apple, Rolex. Blurring happens when a famous mark gets attached to unrelated goods until it stops uniquely signaling one company.
Naming your fictional bakery chain “Rolex Cupcakes” would be blurring. Having a character check her Rolex is not.
3. Dilution by Tarnishment
Tarnishment is the one authors underestimate. It occurs when a famous mark is linked to content that harms its reputation — the classic examples being pornography, illegal drugs, and violence.
The frequently cited case is Dallas Cowboys Cheerleaders v. Pussycat Cinema, where a pornographic film used the cheerleaders’ trademarked uniform. Making a brand the murder weapon or the drug of choice in a graphic scene is the fiction equivalent.
Federal law does carve out breathing room. The dilution statute, 15 U.S.C. § 1125(c)(3), excludes noncommercial use plus news reporting, commentary, criticism, and parody from dilution liability — which covers a great deal of what novelists do.
4. Defamation and Trade Libel
This is the risk with the sharpest teeth, and it has nothing to do with trademarks. If you write that a real restaurant chain knowingly served contaminated meat, you have published a false statement of fact about a real business.
Opinion is protected. Obvious fiction is generally protected. A specific, checkable, false factual claim about a real company is not. The same reasoning governs using real people in fiction, where a fabricated crime attributed to a named person creates the same exposure.
When Brand Names Become a Real Problem
Five scenarios move a mention from routine to risky. If none of these apply, you are almost certainly fine.
- The brand is in your title or on your cover. This is the single biggest risk factor, because it looks like source identification rather than storytelling.
- A product causes harm in your story. A character dying because a named car’s brakes failed implies a real defect.
- The brand appears in sexual, violent, or drug-related content. Classic tarnishment territory.
- The brand is the subject rather than the scenery. A novel about a thinly veiled real company is different from a character drinking its soda.
- You imply endorsement in your marketing. Never let promotional copy suggest a brand partnered with you.
Notice the pattern. Risk scales with prominence and negativity, not with the mere presence of a trademark on the page.
Do You Need Permission to Use a Brand Name?
You do not need permission to mention a brand name in a book. Asking permission is usually counterproductive — it invites a refusal you then have to ignore or obey, and it creates a written record that you knew the company objected. Traditional publishers rarely seek clearance for ordinary in-text mentions.
Permission matters in a different category entirely: copyrighted material. Song lyrics, poetry, and long quotations from other books require licensing, which is a separate question covered in our guide to fair use for authors.
The distinction confuses a lot of writers. Naming a brand is trademark territory. Reproducing creative content is copyright territory. The rules are not the same.
Do You Need to Add the ® or ™ Symbol?
You do not need to add ® or ™ symbols to brand names in a book. Those symbols are notice devices for trademark owners marking their own goods and advertising. Fiction and nonfiction prose carry no such obligation, and publishing house style guides almost universally omit them.
What you should do is capitalize brand names correctly: Kleenex, Band-Aid, Dumpster, Popsicle, Xerox, Jacuzzi. Capitalization signals that you recognize the word as a brand rather than a generic category.
That small courtesy also heads off the polite letters companies send when a book treats their mark as a common noun.
How to Use Brand Names Correctly: 7 Rules
These seven habits cover nearly every situation an author will encounter.
- Use the brand as scenery, not as subject. A mention that could be swapped for a generic term without changing your plot is a safe mention.
- Capitalize the mark and spell it exactly right. Write Coca-Cola, not coca cola. Write Google as a proper noun where you can.
- Never state a false fact about a real product. Fictional characters may hold opinions. Your narration should not assert verifiable falsehoods.
- Keep famous brands away from graphic content. Tarnishment claims cluster around sex, violence, and drugs.
- Keep brands out of your title and cover art. Titles and covers look like source identifiers, which is exactly what trademark law polices.
- Do not genericize marks. “She photocopied the file” is safer than “she xeroxed it,” and the same applies to googling, rollerblading, and dumpstering.
- Invent a brand when the portrayal turns hostile. If a product must fail, poison, or kill, make it fictional.
Follow those seven and you have eliminated the overwhelming majority of realistic exposure.
Keep Brand Usage Consistent Across a Full Manuscript
Legal risk in a long book rarely comes from one deliberate choice. It comes from inconsistency — a brand capitalized in chapter 3, lowercase in chapter 17, and quietly genericized in chapter 24.
Chapter helps here because it drafts your book against a structured outline and a style brief you define up front, so a rule like “capitalize all brand names, never use brands in the crime scenes” carries across every chapter instead of drifting. More than 2,147 authors and 5,000+ books have gone through the platform, and it costs $97 one-time for the nonfiction version.
It is not a legal review, and nothing replaces an IP attorney for a genuinely risky use. It just means your final consistency pass is checking a manuscript that was written to one standard.
Can You Use a Brand Name in Your Book Title?
Using a brand name in a book title is the riskiest placement available to an author. Titles function like source identifiers, so a trademark owner has a far stronger confusion argument than they would over an in-text mention. Courts still protect artistically relevant titles, but you are inviting a fight.
The governing framework is the Rogers v. Grimaldi test: a title survives a trademark challenge if it has some artistic relevance to the work and does not explicitly mislead about source or content.
That is why Breakfast of Champions survived, though Kurt Vonnegut still opened the book with a note disclaiming any connection to General Mills. It is also why unauthorized companion books get sued when their covers mimic a brand’s trade dress.
If you want protection for a title of your own, that is a different project — see our guide to how to trademark a book title.
What the Jack Daniel’s Ruling Changed for Authors
Most articles on this topic predate the Supreme Court’s 2023 decision in Jack Daniel’s Properties v. VIP Products, and it is worth understanding because the outcome was narrower than authors feared.
VIP Products sold a squeaky dog toy shaped like a Jack Daniel’s bottle. The unanimous Court held that when a defendant uses a mark as a source identifier for its own goods, the First Amendment-flavored Rogers screening test does not apply at all.
The Court also held that the noncommercial-use exclusion in the dilution statute does not shield a parody used as a trademark.
Why this matters to you: the ruling turns on using a mark as a mark. A novelist referencing Jack Daniel’s in dialogue is not branding a competing product, so the Rogers protections for expressive works remain intact. What the case tightened is the merchandising edge — the tote bag, the cover, the product line — not the prose.
The practical takeaway is the same rule stated earlier, now with Supreme Court backing: inside the book is safe territory; on the packaging is not.
What About Nonfiction, Memoir, and Business Books?
Nonfiction gets more protection for factual brand discussion and less slack for getting facts wrong.
Reviewing products, analyzing companies, criticizing an industry, and reporting on corporate behavior are core protected speech. Business books name competitors constantly, and the dilution statute’s carve-outs for commentary and criticism apply directly.
The trade-off is accuracy. In fiction, a hostile portrayal reads as invention. In nonfiction, it reads as an assertion of fact — and false assertions of fact are actionable.
Memoir sits in the tightest spot, since you are making factual claims about real brands and real people simultaneously. Our guides to ethical memoir writing and writing a disclaimer for a memoir cover that overlap.
Document your sources for any negative factual claim. Receipts, dated notes, and news citations are your defense.
When to Invent a Fictional Brand Instead
Invented brands solve the hard cases cleanly, and they carry real craft benefits.
Use a fictional brand when the product fails, harms, or kills; when the company is a plot antagonist; when your story is set far enough in the future that today’s brands break the illusion; or when the portrayal is unmistakably unflattering.
Real brands still earn their place in ordinary scenes. Specificity builds texture — a character who drinks Diet Coke reads differently from one who drinks “a diet soda,” and that difference is exactly why strong dialogue and detail work.
When inventing, run a quick USPTO trademark search on your made-up name first. Writers occasionally invent a “fictional” company that turns out to be a real one, which reintroduces every risk you were trying to avoid.
Should You Add a Disclaimer About Brand Names?
A brand-name disclaimer will not defeat a trademark or defamation claim, but it costs nothing and it demonstrates good faith. Standard copyright-page language notes that trademarks appear without permission of their owners, that no endorsement is implied, and that use is editorial only.
Something like this is typical:
All trademarks and brand names mentioned in this book are the property of their respective owners and are used for editorial purposes only. No affiliation with or endorsement by any trademark owner is claimed or implied.
Combine it with the usual fiction disclaimer about characters and events being products of the imagination. Our book copyright page template and how to write a disclaimer for a book show where each line goes.
Do not treat a disclaimer as a license to write something reckless. It is a signal, not a shield.
Common Mistakes to Avoid
- Putting a famous brand in your title or cover art. The highest-risk placement, and easily avoided.
- Turning trademarks into verbs and generic nouns. Genericization is the complaint most likely to draw a letter from a brand’s legal department.
- Asking permission you do not need. A “no” you then ignore looks far worse than never having asked.
- Assuming fiction immunizes false factual claims. Frame a defamatory statement inside a novel and it can still be actionable.
- Confusing trademark with copyright. Naming a band is fine. Quoting four lines of its song is a licensing problem.
- Ignoring non-US law. The UK, EU, and Australia handle disparagement and comparative use differently. Global distribution means global exposure.
How Likely Is It That a Brand Actually Sues an Author?
Lawsuits against authors over in-text brand mentions are rare. Companies monitor advertising and merchandising, not novels, and suing a writer for naming a product generates terrible publicity for a case that is hard to win. Cease-and-desist letters over genericization are far more common than litigation.
Rarity is not the same as immunity, though. The authors who do get letters tend to have made one of the five high-risk choices listed earlier — usually a brand in the title or a product implicated in harm.
Treat the low base rate as a reason to write confidently, not as a reason to skip the seven rules.
Do Publishers Have Their Own Brand-Name Rules?
Most traditional publishers apply house style rules to brand names rather than legal clearance. Copy editors verify spelling and capitalization against a style guide, flag genericized marks, and escalate only unusual uses to the legal department for review.
Self-published authors have no such safety net, which makes the seven rules above your own editorial checklist. Add a manuscript-wide search for brand names to your final pass, the same way you would check your copyright registration before publication.
If a brand carries genuine risk in your book, budget for an attorney’s manuscript review. It is far cheaper than a dispute.
FAQ
Can you use brand names in a book without permission?
You can use brand names in a book without permission in most circumstances. Simple references to real products fall under nominative fair use, since you are identifying the actual product rather than branding your own goods. Permission is only worth pursuing for copyrighted content such as song lyrics or extended quotations.
Is it illegal to mention a company in a novel?
It is not illegal to mention a company in a novel. Fiction is protected expression, and naming a real business creates no likelihood of confusion about who published your book. Liability arises only if you publish false statements of fact that damage the company or link a famous mark to degrading content.
Do I need to use the trademark symbol in my book?
You do not need to use the ® or ™ symbol in your book. Those symbols are notice tools for trademark owners marking their own products and advertising, not obligations for authors. Correct capitalization of the brand name is the standard publishing convention and is sufficient.
Can I use a brand name in my book title?
Using a brand name in a book title is legally risky because titles can function as source identifiers. Under the Rogers v. Grimaldi test, a title survives if it has artistic relevance and does not explicitly mislead about source. Consult an IP attorney before committing to one.
What happens if a company objects to my book?
Most companies that object to a book send a cease-and-desist letter rather than filing suit. The letter typically demands a correction, a disclaimer, or a change in a future printing. Do not respond alone — forward it to a trademark attorney, since your first reply can affect the whole dispute.
Can I use brand names in a memoir?
You can use brand names in a memoir, and factual descriptions of real products enjoy strong protection. The greater risk is defamation: memoir presents claims as true, so any negative statement about a company should be documented and verifiable before publication.
