Received a warning letter in trademark law? How to react correctly.
✅ What to do in the event of a trademark warning?
Who wants a Warning letter due to trademark infringement should immediately consult a lawyer specializing in trademark law. In many cases, high contractual penalties, temporary injunctions and costly court proceedings are a threat - especially if you react incorrectly or prematurely. As a specialist lawyer for intellectual property law with many years of experience in trademark law, I advise and represent you nationwide against warning letters - competently, efficiently and with a clear focus on your economic interests.
⚠️ What is a warning letter in trademark law?
A warning letter under trademark law is a formal request from a trademark owner (or their lawyer) to cease and desist from a specific trademark infringement. The warning letter usually contains:
-
a detailed description of the alleged trademark infringement,
-
a request to submit a cease-and-desist declaration subject to penalty,
-
the assertion of warning costs (lawyer's fees),
-
claims for damages, if applicable.
Not every warning is justified. There are numerous ways to defend yourself against unjustified or exaggerated claims. An initial check by a lawyer will quickly show whether a trademark infringement has occurred and what options there are for responding.

📍 Why you should not react yourself
Many of those affected initially try to contact the law firm issuing the warning themselves - for example, to "clarify the matter" or "explain everything". This is a mistake.
💬 Even a wrong sentence or an ill-considered reaction can be interpreted as an admission of guilt.
In addition, many cease-and-desist declarations are deliberately worded broadly in order to lead you into the contractual penalty trap in the future. I modify the cease-and-desist declaration in such a way that your risks are minimized - without losing the legally necessary effect.
🧾 Costs of a warning letter in trademark law
The Warning costs are based on an object value, which is often between 50,000 and 600,000 euros values of 150,000 euros and 250,000 euros are typical. This results in legal fees of several hundred to several thousand euros.
Depending on the case Claims for damages possible - for example according to the so-called "fictitious license agreement". This is referred to as "license analogy". These can also often be successfully defended against or reduced - especially in the case of insignificant or unproven infringements.
❌ Unjustified or abusive warning letter? How to defend yourself
Not every warning letter is justified. Many trademark applications are purely descriptive and many trademark owners overestimate their rights. Trademark law Abuse of warnings (e.g. through mass warnings or systematic rip-offs) is not uncommon.
We carefully check whether a claim for injunctive relief under trademark law exists at all - and whether the trademark owner may actually assert rights against you. In many cases, a well-founded letter from a lawyer can reject the entire warning letter or at least defuse its content.
