A trademark cease-and-desist letter is a serious legal warning. Anyone who ignores it or signs the enclosed undertaking without review risks economic damage that exceeds the original demand many times over.

Trademark infringement exists where you use an identical or confusably similar sign for identical or similar goods or services — without the consent of the owner of the registered mark. The typical constellations:

  • Identical product name introduced without a search
  • Confusingly similar domain name registered
  • Logo design modelled on a well-known brand
  • Advertising with a third party’s trademark without authorisation
  • Imported goods with unauthorised trademark marking

The most common mistakes after receipt of a cease-and-desist

  • Leaving the cease-and-desist unanswered or ignoring it
  • Signing a pre-formulated undertaking without review
  • Publicly commenting on the content (e.g. on social media)
  • Negotiating with the other side on your own
  • Destroying evidence (releasing a domain, scrapping goods) — that hurts the defence

What you must do immediately

Suspend the challenged use immediately — that prevents further “damage deepening”. But: before you sign or pay anything, have the cease-and-desist reviewed by a lawyer. The enclosed undertaking is as a rule formulated in favour of the sender and often contains declarations going considerably beyond what is necessary.

Once signed, a cease-and-desist undertaking is binding — and cannot be unilaterally revoked. It often binds you and possibly your legal successors for years.

Modified undertaking as protection

A lawyer-drafted, modified cease-and-desist undertaking limits the cease-and-desist claim to the actually challenged conduct, sets an appropriate contractual penalty and preserves room for manoeuvre for your own future trademark use. It eliminates the risk of repetition — without you taking on excessive obligations.

Defence strategies

Not every cease-and-desist is justified. Common defence approaches:

  • No likelihood of confusion (different classes, different target group, different industry)
  • Lapse of the opposing mark due to non-use (5 years)
  • Own earlier rights (company, work title or name rights)
  • Weak scope of protection of the opposing mark (low distinctiveness)
  • Exhaustion of the trademark right (e.g. with parallel imports)

Which strategy applies we clarify after reviewing the cease-and-desist.

Deadlines are not coincidence

Cease-and-desist deadlines of 7 to 14 days are deliberately short — they are meant to create pressure and prevent reflection. The same applies to you: react fast, but with consideration — don’t sign in panic.
