Got a Trademark Cease-and-Desist Letter? First, Stay Calm

A letter in your mailbox, the sender a law firm, the subject line "trademark infringement." For many founders, that is the moment the pulse starts racing. Take a breath first. A cease-and-desist letter is, to begin with, an out-of-court document, not a court judgment and not a lost case. Legally, it is the assertion of a claim to cease and desist under § 14 (5) MarkenG (Gesetze im Internet, 2026). This guide gives you a calm, general orientation: what such a letter actually is, the legal basis it rests on, why it often demands money too, and why it is wise to seek legal advice early. One thing up front, very plainly: this is not legal advice. With a concrete warning letter, your case belongs in the hands of an attorney.

Key Takeaways

• A cease-and-desist letter is the out-of-court assertion of a claim to cease and desist (§ 14 (5) MarkenG, 2026), not yet a judgment.
• Alongside the cease and desist, there are often monetary demands, because the law provides for damages (§ 14 (6) MarkenG, 2026).
• The DPMA does not examine the older rights of third parties, which is why unknowing collisions are possible (DPMA, 2026).
• An enclosed cease-and-desist declaration is a serious step that often binds you for the long term.
• Warning-letter costs follow the RVG: at the routinely applied dispute values of €50,000 and up, a 1.3 business fee works out to roughly €1,700 net.
• Stay calm, observe the set deadline (often a few days to about two weeks), and seek legal advice early.

If you are still in the middle of naming, it pays to look ahead: you can always search your trademark yourself before it ever comes to this.

Received a trademark cease-and-desist letter: the first steps

With the letter in front of you, a sober sequence helps more than any hectic reaction. These steps have proven useful as orientation:

1. Note the deadline. The deadline set in the letter is the most important pacesetter. Put it in your calendar immediately, with a buffer before it.
2. Sign nothing in haste. Above all, not the enclosed cease-and-desist declaration. It often binds you for years (more on that below).
3. No contact with the other side on your own initiative. A well-meant phone call or quick email can contain concessions that are later used against you.
4. Secure your records. Since when have you used the name? Screenshots, invoices, register extracts, domain registration: anything that documents your use and when it began will be needed for the assessment.
5. Seek legal advice early. A specialist attorney for intellectual property assesses whether the accusation holds and takes over the response.

This is deliberately a general checklist and not legal advice. It does not replace any of the steps; it only puts them in order.

Anyone who has received a trademark cease-and-desist letter should first note the deadline, sign nothing in haste, not communicate with the other side on their own, secure proof of use, and seek legal advice early. This sequence prevents the most expensive mistakes of the first 48 hours.

What is a trademark cease-and-desist letter, anyway?

A warning letter is the out-of-court assertion of a claim to cease and desist. Under § 14 (5) MarkenG (Gesetze im Internet, 2026), the trademark owner can demand that you stop a particular use. Notably, this claim can arise as soon as an infringement first threatens to occur. So the warning letter is a letter that comes before the court, not a court.

The idea behind it is actually meant to be calming. Instead of suing right away, the owner gives you the chance to settle the matter out of court. That saves both sides time and money. A sharp tone in the letter does not change the fact that it is, at first, an offer to clarify things.

Even so, you should not ignore it. A letter that simply fizzles out can lead to a preliminary injunction or a lawsuit. Calm therefore does not mean doing nothing. It means: read it soberly, make sense of it, and get professional advice for your response. This remains general orientation, not legal advice.

A trademark cease-and-desist letter is the out-of-court assertion of a claim to cease and desist under § 14 (5) MarkenG (Gesetze im Internet, 2026). The claim can arise as soon as an infringement first threatens to occur. The warning letter is thus a pre-court document that offers clarification, and not yet a judgment about a trademark infringement.

What does such a letter rest on legally?

On the accusation that you are using a protected sign without authorization. § 14 (2) MarkenG (Gesetze im Internet, 2026) describes three cases: an identical sign for identical goods, a similar sign that creates a likelihood of confusion, or taking unfair advantage of or harming a well-known trademark. Most letters rest on one of these cases.

Worth knowing: the trigger does not have to be a registered trademark. Commercial designations, meaning company and business names, also enjoy their own claims to cease and desist and to damages (§ 15 MarkenG, 2026). A warning letter can therefore also rest on an older company name that you never found in the register in the first place.

What actually applies in a specific letter is an assessment of the individual case. Whether a likelihood of confusion really exists, whether the other side's right is older, whether the amount of their demand holds up: only an attorney can judge all of that reliably. So read the letter carefully, but do not draw your legal conclusions on your own.

A trademark cease-and-desist letter rests on § 14 (2) MarkenG (Gesetze im Internet, 2026): an identical sign for identical goods, a similar sign with a likelihood of confusion, or taking unfair advantage of a well-known trademark. Commercial designations such as company names are also protected (§ 15 MarkenG, 2026), so a warning letter can be based on a company name.

Likelihood of confusion: the core of the accusation

Most warning letters share the same legal core: the accusation of a likelihood of confusion under § 14 (2) no. 2 MarkenG (2026). What is meant is that the public could confuse your sign with the older trademark or mentally associate the two.

Whether that is the case depends above all on two questions: How similar are the signs in sound, appearance, and meaning? And how similar are the goods or services they each stand for? The two interact: a high similarity of signs can offset a lower similarity of goods, and vice versa.

How these factors interlock in detail, and how to structure a first assessment of your own, is covered at length in a dedicated article: Assessing likelihood of confusion: the factors at a glance. For the warning-letter situation, the core point suffices: the evaluation is a legal weighing exercise, not a mechanical comparison, and in a conflict it belongs in an attorney's hands.

The core of most trademark warning letters is the likelihood of confusion under § 14 (2) no. 2 MarkenG (2026). It results from the interplay of sign similarity (sound, appearance, meaning) and similarity of goods and services, with the two factors able to offset each other.

Why do the demands often include money and disclosures, not just the cease and desist?

Because trademark law gives the owner several claims, not only the one to cease and desist. In cases of intent or negligence, § 14 (6) MarkenG (Gesetze im Internet, 2026) provides for a claim to damages. The calculation of those damages may take into account the infringer's profit or a reasonable license fee. That is why concrete monetary demands often appear alongside the cease and desist.

A third element explains the often extensive questions in the letter. § 19 MarkenG (2026) gives the owner a right to information. They may want to know to what extent you used the sign, which quantities, which buyers, which time periods. Precisely for that reason, many warning letters request detailed disclosures in addition to the cease and desist.

Do not let this combination rattle you. Several demands in one letter is common and follows the structure of the law. That does not mean each one is justified and reasonable in amount, however. That is a question for an attorney's assessment, not for a quick, gut reaction.

A warning letter often bundles several claims. Alongside the cease and desist, § 14 (6) MarkenG (Gesetze im Internet, 2026) provides for damages in cases of intent or negligence, calculable via the infringer's profit or a reasonable license fee. § 19 MarkenG (2026) additionally grants a right to information. That explains why such letters demand money and detailed disclosures at the same time.

Damages and warning-letter costs: what amounts are typically involved?

Two items need to be kept apart: the damages for the alleged infringement, and the warning-letter costs, meaning the reimbursement of the other side's attorney fees. They follow different calculation paths.

For damages, § 14 (6) MarkenG (2026) knows three calculation methods: the owner's actual loss, surrender of the profit you made from the use, or the so-called license analogy, the notional fee you would have paid for a proper license. In practice, the license analogy is often chosen because it is the easiest to quantify. There is no fixed amount; the figure is always an individual assessment.

For the warning-letter costs, the calculation is more transparent, because it follows the German attorney fee act (RVG, Gesetze im Internet, 2026). The starting point is the value in dispute. In trademark matters, €50,000 and more is routinely applied, because the value of a trademark is considered high. From a dispute value of €50,000, a standard 1.3 business fee works out to roughly €1,700 net. That explains why many letters contain four-figure reimbursement demands, without that being an alarm signal in itself.

Important for context: the fact that this system is common does not mean every applied value and every demand is appropriate in your specific case. Dispute value, fee rate, and damage calculation are classic points of contention that an attorney reviews. This section describes the usual system and is not legal advice.

Warning-letter costs in trademark law follow the RVG (2026): at the routinely applied dispute values of €50,000 and more, a 1.3 business fee works out to roughly €1,700 net. The damages themselves are calculated under § 14 (6) MarkenG (2026) via actual loss, infringer's profit, or license analogy. Whether value and amount are appropriate in a specific case is for an attorney to assess.

How can it happen that you infringed without knowing?

Because a trademark registration does not check whether you are encroaching on someone else. The DPMA examines applications only for absolute grounds for refusal, such as a lack of distinctiveness, but not for the older rights of third parties (DPMA, 2026). Your own registration is therefore neither a free pass nor protection against touching someone else's older trademark.

This surprises many founders. They think, "My trademark is registered, so I'm on the safe side." In truth, the responsibility for avoiding older rights lies with you. Anyone who starts without a prior similarity search can collide with a nearly identical sign without ever having noticed it.

This is exactly where the useful point lies: the risk can be lowered considerably in advance. A similarity search reveals trademarks that are close in sound, appearance, and meaning, along with the classes affected, before you commit. It does not replace a legal assessment, but it reduces the chance of unknowingly running into someone else's trademark in the first place.

The DPMA examines trademark applications only for absolute grounds for refusal, not for the older rights of third parties (DPMA, 2026). Your own registration therefore does not protect you from infringing an older third-party trademark. Anyone who collides unknowingly can receive a warning letter for exactly that reason. A prior similarity search noticeably lowers this risk.

What is the deal with the cease-and-desist declaration?

It is usually the central document in the enclosure, and signing it is a serious step. A pre-drafted cease-and-desist declaration with a penalty clause removes what is known as the risk of repetition, which is the core of the claim to cease and desist under § 14 (5) MarkenG (2026). That is exactly why it is so important to the other side.

Here is the tricky part: such a declaration often binds you for the long term, in many cases over years. A "penalty clause" means that a contractual penalty becomes due for every future violation. A pre-drafted declaration is also, when in doubt, worded in the other side's favor, meaning broader than would be necessary to remove the risk of repetition.

So, without alarm but clearly: do not sign something like this in the first shock. Whether you should sign at all, whether the wording goes too far, whether an adjusted declaration would make more sense: these are classic questions for an attorney. An ill-considered signature can hardly be taken back. This section is general orientation and expressly not legal advice.

A pre-drafted cease-and-desist declaration with a penalty clause removes the risk of repetition in the claim to cease and desist (§ 14 (5) MarkenG, 2026) and often binds you for years. A contractual penalty looms for every future violation. An ill-considered signature is a serious, almost irreversible step. When in doubt, such a declaration belongs in an attorney's review before you sign.

Why is it worth staying calm and getting advice early?

Because a warning letter can set a deadline, and the tone rarely matches the actual scale of the matter. The law names no rigid number of days for your response; the deadline that is set depends on the individual case. In practice, the deadlines set in such letters often range from a few days to about two weeks, and less when the matter is urgent. If the deadline lapses without a response, the owner can apply for a preliminary injunction or file a lawsuit, which makes the matter considerably more expensive. Precisely for that reason, it is wise neither to drag things out nor to act out of panic. Both can become expensive.

Calm is a genuine strategy here. A cool head reads the letter carefully, gathers its own records, and examines the sober questions: Is the other side's right really older? Is there a likelihood of confusion at all (§ 14 (2) MarkenG, 2026)? Is the amount of the demand plausible? These questions decide the matter, not the moment of shock at the mailbox.

You should not answer them on your own, though. In trademark law, early legal advice is often the cheapest option, because it prevents expensive mistakes before your first response. A specialist attorney for intellectual property makes sense of the situation and takes over the communication. In short: stay calm, keep the deadline in view, and put the case in expert hands.

A warning letter usually sets a deadline whose length depends on the individual case, not on a fixed statutory number of days. It is therefore sensible to stay calm, observe the deadline, and seek legal advice early. A specialist attorney examines whether a likelihood of confusion (§ 14 (2) MarkenG, 2026) and the amount of the demand hold up at all.

How does a prior search lower the risk from the outset?

By making collisions visible before you commit to a name. Because the DPMA does not examine the older rights of third parties (DPMA, 2026), that task stays with you. A similarity search shows you nearby trademarks and their classes early enough to keep expensive surprises, such as a later warning letter, from arising in the first place.

The difference lies in the depth of the search. A pure identity search finds only the exactly identical name and misses signs that are similar in sound or appearance, which is where the real risk sits. A similarity search checks your desired name against the register by sound, by appearance, and by meaning. It thereby uncovers exactly the hits that lead to conflicts later.

The framing remains important: a search is not a legal assessment and does not replace an attorney in the event of a conflict. It does, however, shift the effort to the right place, namely to the front, where it is cheap. Anyone who searches early sets out with a noticeably smaller risk. A structured EUIPO trademark search shows similar trademarks along with their classes before the logo and domain are paid for.

Because the DPMA does not examine the older rights of third parties (DPMA, 2026), the responsibility lies with the applicant. A similarity search checks by sound, appearance, and meaning, not just for identity, and makes potential collisions visible early. It does not replace a legal assessment, but it lowers the risk of unknowingly infringing someone else's trademark and being sent a warning letter.

Conclusion: make sense of it calmly, get advice early, search in advance

A trademark cease-and-desist letter feels threatening, but it is first of all an out-of-court document, the assertion of a claim to cease and desist under § 14 (5) MarkenG (2026). Alongside the cease and desist, it can demand damages (§ 14 (6) MarkenG, 2026) and disclosures (§ 19 MarkenG, 2026), and it can also rest on a company name (§ 15 MarkenG, 2026). That makes it serious, but not hopeless.

Three things stick. First: stay calm, read the letter carefully, sign nothing in the shock of the moment. Second: get legal advice early, because the legal assessment belongs in expert hands. This guide is general orientation, expressly not legal advice. Third, for the future: anyone who searches carefully before filing noticeably lowers the risk of unknowingly colliding at all.

The best time for a search is before it ever comes to this. Before you commit to a name, you can search your trademark yourself and start out on the safe side.
