Does this sound familiar?

Your competitor advertises “test winner” without any test.

Seals, superlatives and test results without reliable proof are misleading. We secure the evidence and send the cease-and-desist letter before the deadline for preliminary injunction proceedings expires.

Your product is being copied and sold for less.

If the imitation deceives about the origin, it can be stopped under competition law, in some cases even without a registered trademark or design.

A competitor lures customers with fantasy discounts.

Crossed-out prices without a genuine previous price, permanent discounts, “up to” promises: anyone who advertises like this wins customers at your expense. They have to stop.

A provider from abroad ignores German rules.

Anyone who targets customers in Germany must comply with German competition law. We also send cease-and-desist letters to foreign companies.

If your cease-and-desist letter is justified,
the other side usually pays.

The recipient must reimburse the necessary legal costs (§ 13 para. 3 UWG). Exception: for violations of information and labelling obligations on the internet and for many data protection violations, there is no cost reimbursement between competitors (§ 13 para. 4 UWG). We clarify in advance whether your case falls under this.

How it works

  1. Describe the violation

    A link, a screenshot or a few sentences are enough.

  2. Free initial assessment

    We tell you whether a cease-and-desist letter is likely to succeed, what it costs and who pays in the end.

  3. You decide, we act

    Costs only arise once you instruct us. Then we send the cease-and-desist letter and enforce cessation, by preliminary injunction if necessary.

What clients say

After founding Bone Brox GmbH, the lawyers at ab&d – especially Tobias Bystry – supported us hands-on in all matters of competition law and corporate law. Particularly noteworthy – they do not just negotiate and draft contracts, they always think commercially too […]

Konrad Knops Founder, Bone Brox GmbH

The firm works very professionally and swiftly. […] My special thanks go to Dr. Joanna Koronkiewicz, who […] explained the finer points of German competition and trademark law relevant to my case in a very understandable and friendly manner. Professionalism at the highest level.

Roman Google review, May 2026

[…] The advice was given in a way that avoided litigation wherever possible – but when unavoidable, every resource was deployed, resulting in several court successes together.

Philipp Stern Managing Director, Stern & Schatz GmbH

I would like to sincerely thank the law firm ab&d and especially my attorney Dr. Dauskardt. From the very beginning I was treated in a very friendly, attentive and professional manner. Dr. Dauskardt works extremely carefully, competently and reliably. […]

Frequently asked questions

What does a cease-and-desist letter cost me?

The initial assessment is free of charge. If the letter is justified, the other side must in principle reimburse the necessary legal costs (§ 13 para. 3 UWG). Between competitors, exceptions apply above all to violations of information and labelling obligations on the internet. We tell you what to expect before any costs arise.

Am I even allowed to send a cease-and-desist letter to my competitor?

Yes, if you offer similar goods or services to a not insignificant extent and not just occasionally (§ 8 para. 3 no. 1 UWG). That is the first thing we check.

How quickly do I have to act?

As quickly as possible. Depending on the court, only about four weeks to two months remain after you become aware of the violation to apply for a preliminary injunction. The claims themselves become time-barred after six months (§ 11 UWG).

What if the other side does not respond?

Then we apply for a preliminary injunction. The court can prohibit the violation within a few days. Any further violation can then cost the other side an administrative fine of up to EUR 250,000.
