When another business starts using a name or logo close to yours, the first instinct is often to fire off a cease and desist letter. That letter can be the cheapest, fastest way to protect your brand, or it can hand the other side a lawsuit you did not want. Trademark substance is mostly federal: the Lanham Act, 15 U.S.C. § 1114 and § 1125, defines infringement and the relief a court can order. Minnesota layers a state trademark registration and its own unfair-competition claim on top. In my practice advising Minnesota companies, the trademark disputes that go badly are usually the ones where the first letter promised more than the facts could support. For broader context, see our Minnesota trademark practice.
What is a trademark cease and desist letter, and what does it do?
A trademark cease and desist letter is a written demand asking another business to stop using a mark that you believe is confusingly similar to yours. It opens a dispute. It does not resolve one, and it has no independent legal force: a letter is not a court order, and the recipient is free to disagree. What gives the letter weight is the claim behind it. Federal law makes a business liable when it uses in commerce a “colorable imitation of a registered mark” in a way that is “likely to cause confusion” (15 U.S.C. § 1114). The letter is a preview of that claim.
Because it is a preview, every word carries consequences from the moment you send it. A measured letter invites a phone call and a quick resolution. An overstated one invites a defensive response, or worse, a lawsuit filed by the recipient in a court of its choosing. Treat the letter as the opening move in a negotiation you would rather win at the table, not the courthouse.
How to decide between a cease and desist letter and a lawsuit
In most ordinary trademark disputes, send a letter first. Litigation is slow and expensive, and a clear letter resolves a large share of disputes before a complaint is ever filed. A lawsuit also commits you publicly and financially in a way a letter does not. The letter-first path keeps your costs low and leaves room to settle.
The exception is the recipient who is likely to race to its own preferred court. A cease and desist letter can give the recipient the legal footing to file first under the Declaratory Judgment Act and ask a court to declare that it is not infringing. If you have strong reason to expect that response, and the forum matters to you, filing suit first can secure the court you want.
| Approach | Best when | Tradeoff |
|---|---|---|
| Send a letter first | Ordinary dispute; you want a fast, low-cost resolution | The recipient may file a declaratory judgment suit in its own chosen court |
| File suit first | The recipient is likely to sue first, and the forum matters to you | Higher cost and a public commitment before any chance to settle quietly |
Most Minnesota business owners are well served by the letter-first path. The suit-first move is the deliberate exception, not the default.
How trademark registration status shapes a cease and desist letter
No. You do not need any registration to send a cease and desist letter, though what you hold shapes how strong the demand is. A federal registration on the Patent and Trademark Office register is the strongest basis: it supports a direct infringement claim and serves as nationwide notice of your rights. But an unregistered mark still carries rights. Federal law reaches a business whose use of a word, name, or symbol “is likely to cause confusion … as to the affiliation, connection, or association” with another business (15 U.S.C. § 1125). That claim is available even without a registration certificate.
Minnesota offers a middle option. Under Minn. Stat. § 333.20, “any person who adopts and uses a trademark or a service mark in this state may file in the Office of the Secretary of State an application for registration,” for a modest filing fee. A state registration does not replace a federal one, but it adds a documented state-law basis for your claim. Before sending any letter, it helps to know exactly what you hold: an audit of your trademark portfolio confirms whether your rights rest on federal registration, state registration, or use alone. Whether your claim depends on earlier use of the mark also matters, and our discussion of Minnesota registration compared with common-law rights covers how those bases differ.
What should a Minnesota trademark cease and desist letter actually demand?
A cease and desist letter should make specific, proportionate demands tied to relief a court could actually order. The central demand is almost always to stop the infringing use. Federal courts “have power to grant injunctions, according to the principles of equity and upon such terms as the court may deem reasonable, to prevent the violation of any right of the registrant” (15 U.S.C. § 1116). An order stopping the use is the relief most often sought and most often granted.
Beyond stopping the use, federal law lets a prevailing trademark owner “recover (1) defendant’s profits, (2) any damages sustained by the plaintiff, and (3) the costs of the action” (15 U.S.C. § 1117). Minnesota’s trademark statute is parallel for a state-registered mark: the owner “may bring an action to enjoin” the wrongful use, and a court may require a defendant to pay “all profits derived from” and “all damages suffered by reason of” the wrongful use, and may order infringing items “delivered to an officer of the court, or to the complainant, to be destroyed” (Minn. Stat. § 333.29). A practical letter asks for the change in conduct first, names a profits-and-damages accounting and destruction of infringing materials where the facts warrant it, and leaves out demands the evidence cannot support.
What evidence should I attach to a trademark cease and desist letter?
Attach the proof that makes the claim credible. The legal question in nearly every trademark dispute is whether the other business’s use is “likely to cause confusion” (15 U.S.C. § 1114), so the attachments should let the reader see that risk for themselves. Three items do most of the work: proof of your rights (a registration certificate, or dated evidence of first use); side-by-side images of the two marks; and evidence the marks appear on related goods or services sold to overlapping customers.
A letter that asserts confusion without showing it reads as bluster. A letter that lays the two marks next to each other and shows them on competing products reads as a claim the recipient’s own lawyer will take seriously. The strength of the attachments often decides whether the recipient negotiates or digs in. Our explainer on how likelihood of confusion is the legal test walks through the factors a court weighs, and our collection of real-world infringement scenarios shows how that test plays out.
How aggressive should the tone of the letter be?
Match the tone to the strength of your claim and the relationship between the businesses, not to how frustrating the situation feels. A well-supported claim against a clear infringer can be direct and firm. A close case, or a letter to a company you may keep doing business with, calls for a more measured approach that leaves room to resolve the matter without a fight.
The recurring mistake is the letter that overstates: broad threats, an aggressive deadline, claims of damages the facts will not support. An overstated letter does two things that work against you. It hardens the recipient, making a quick settlement less likely. And it raises the odds that the recipient files a declaratory judgment suit, because aggressive language is exactly what a court looks at when deciding whether a real dispute exists. The most effective letters I send are confident about the rights and restrained about the rhetoric.
How a declaratory judgment action turns a demand letter against the sender
A cease and desist letter can give the recipient the right to sue you first. The Declaratory Judgment Act lets a federal court, “[i]n a case of actual controversy within its jurisdiction,” declare the parties’ rights “whether or not further relief is or could be sought.” A business that receives a trademark demand can use that statute to file in a court it prefers and ask for a declaration that it is not infringing. You would then be the defendant, in a forum the other side chose, defending the very claim your letter raised.
The hinge is whether an “actual controversy” exists. Courts apply the standard the Supreme Court set in MedImmune, Inc. v. Genentech, Inc., 549 U.S. 118 (2007): they ask “whether the facts alleged, under all the circumstances, show that there is a substantial controversy, between parties having adverse legal interests, of sufficient immediacy and reality to warrant” relief. A firm, specific demand letter can satisfy that test on its own. This is the strongest reason to keep a letter proportionate: the more it reads like an imminent lawsuit, the easier it is for the recipient to turn it into one on its own terms. A recipient who files first may also bring counterclaims the recipient can raise, and one defending its own mark will often be proving common-law trademark rights of its own.
How an overreaching cease and desist letter creates fee exposure
Yes, and the financial risk is concrete. If you send a demand and then sue on a claim you knew had no real basis, you can be ordered to pay the other side’s legal bill. Minnesota’s Deceptive Trade Practices Act provides that a court “may award attorneys’ fees to the prevailing party if … the party complaining of a deceptive trade practice has brought an action knowing it to be groundless” (Minn. Stat. § 325D.45). That statute reaches trademark-style disputes because it treats conduct that “causes likelihood of confusion or of misunderstanding as to the source, sponsorship, approval, or certification of goods or services” as a deceptive trade practice (Minn. Stat. § 325D.44).
Federal law carries a parallel risk. The Lanham Act provides that “[t]he court in exceptional cases may award reasonable attorney fees to the prevailing party” (15 U.S.C. § 1117), and the prevailing party can be the defendant. A trademark owner who pushes a weak claim too hard can end up paying for the dispute it started. The recipient may also have equitable defenses available to the recipient, and a trademark owner who waited too long before complaining can face a laches defense based on delay. A letter grounded in real rights and honest facts avoids all of this.
How do trademark disputes usually settle after a cease and desist letter?
Most trademark disputes settle without a trial, and they tend to settle through one of a few standard structures. A phase-out gives the other business a defined period to wind down the infringing use, which is common when the use was innocent and recent. A coexistence agreement lets both businesses keep their marks under agreed limits on territory, product categories, or how each mark is presented. A trademark license has one party formally permit the other’s use, often for a fee, when the trademark owner would rather collect value than shut the use down.
The most formal option is a consent judgment, where the parties agree to the resolution and ask the court to enter it as an order. A consent judgment matters when you want the resolution enforceable through the court rather than as a private contract: Minnesota’s trademark statute already lets a registered owner “bring an action to enjoin” wrongful use (Minn. Stat. § 333.29), and a consent judgment puts that enforcement power behind the deal. Our discussion of a consent judgment on the court record covers when that added formality is worth it. Which structure fits depends on how much the businesses actually compete and how much each values its mark.
Can I demand that another business stop using a name I use only in Minnesota?
Yes. An unregistered mark used in Minnesota can support a claim, and a Minnesota Secretary of State registration adds a state-law basis. How far you have used the mark affects how far your rights extend, not whether you can send the letter.
Do I have to give the recipient a deadline to respond?
No statute requires a deadline. A short, reasonable response window is common practice. A harsh ultimatum can read as a threat that helps the recipient argue an actual controversy exists, which is what a court looks for before it hears a declaratory judgment suit.
What if I receive a trademark demand and do nothing?
Ignoring it does not make the claim go away. The sender can still file suit, and continued use of the mark after written notice can support a finding that the infringement was willful. Under federal trademark law, willfulness raises the financial exposure.
Is a coexistence agreement a good way to resolve a trademark dispute?
Often, yes. A coexistence agreement lets both businesses keep using their marks under defined limits on territory, goods, or presentation. It works well when the marks are similar but the actual overlap in customers is small.
Should I send the letter myself or have an attorney send it?
A letter on counsel’s letterhead signals the claim is serious and is less likely to contain an overstatement that creates declaratory judgment exposure. Either way, the legal claim and the evidence behind it matter more than the signature.
What happens if the other business was using the mark before I was?
Earlier use generally wins. Trademark rights in the United States flow from priority of use. If the recipient can show first use, your cease and desist letter may be met with a claim that you are the one who must stop.
A cease and desist letter is a useful tool, but it is a tool with a sharp edge. A letter grounded in real rights, supported by clear evidence, and proportionate in its demands resolves most trademark disputes quickly and cheaply. A letter that overreaches can invite a lawsuit in the wrong court and, in a weak case, leave you paying the other side’s fees. The deciding factor is almost always the work done before the letter goes out: knowing exactly what rights you hold and what the evidence will support.
