Competition law: key matters at a glance
Unfair competition and commercial practices
The German Act Against Unfair Competition (UWG) addresses unfair commercial practices, including certain misleading statements, omissions and other conduct capable of affecting competitors or consumers. The legal assessment depends on the exact wording, presentation, audience and market context.
Online shops and platform listings can combine competition-law questions with consumer-information and contract-law requirements. A preventive review can therefore be useful before campaigns or shop changes go live.
Cease-and-desist letters and undertakings
A competition-law notice should not be treated as a formality. The alleged infringement, the sender’s standing, the requested undertaking, contractual penalties and cost demands should be examined before a binding declaration is signed.
On the enforcement side, the wording of a notice and the evidence supporting the claim can influence later court proceedings.
Urgent proceedings and defence
Preliminary injunction proceedings may be relevant where rapid court intervention is required. The timing requirements and procedural strategy depend on the court and the specific facts; both applicants and respondents should preserve evidence and evaluate the wider consequences of the requested order.
This overview concerns typical issues under German unfair competition law. Advertising, standing, urgency and available remedies must be assessed on the facts of the individual case.
