Competition Law – Your attorneys for Unfair Competition & Commercial Legal Protection


Cease-and-Desist Letters & Legal Protection in Competition Law

Competition law governs the fair interaction between businesses in the market and is also referred to as unfair competition law, advertising law, or commercial legal protection. As competition law attorneys, our goal is to help ensure a level playing field in the marketplace. The legal foundation is the German Act Against Unfair Competition (UWG) and related statutes.

Competitors can take legal action against unfair practices. This includes cease-and-desist letters and preliminary injunctions, which are effective tools against unlawful advertising – whether in social media, online shops, or brick-and-mortar retail. These tools also help stop deceptive advertising tactics.

Your attorney for Competition Law

Enforcing fair competition rules is a key task in the market. However, enforcement is not handled by the state, but rather by competitors, consumer protection organizations, or watchdog associations.

A competition law attorney’s responsibilities also include reviewing marketing measures, protecting business secrets, and drafting contract clauses such as non-compete agreements. In today’s digital world, defending against unjustified cease-and-desist letters is more important than ever.

Competition Law: Key Tips when you receive a Cease-and-Desist Letter

If you receive a cease-and-desist letter, act quickly, calmly, and thoroughly within the given deadline – otherwise, you risk costly court action.

Always remember:

  • Stay calm and read the letter carefully – more than once if needed
  • Check whether the facts are correct
  • Do not contact the opposing party or their attorney directly
  • Do not sign any undertakings hastily
  • Do not pay the claimed legal fees immediately

Carefully check:

  • Is your company correctly and fully named?
  • Are the facts presented accurate?
  • Is the opposing party actually a competitor?
  • Has the other party possibly violated any advertising rules themselves?

After this, consult a competition law attorney. Legal professionals specializing in unfair competition, advertising law, and trademark law may also hold the official title of “Certified Attorney for Commercial Legal Protection.”
