Trademark Infringement Warning Letter Template for Germany

A Trademark Infringement Warning Letter is your first line of defense when someone is using your trademark without permission in Germany. This formal document puts infringers on notice that they are violating your trademark rights and demands they stop immediately. Under German law, sending this warning letter is often a required step before you can take the matter to court, making it a crucial part of your intellectual property enforcement strategy.

When do you need this document?

You need a Trademark Infringement Warning Letter when you discover someone using your trademark or a confusingly similar mark without authorization. This commonly occurs when competitors copy your brand name, logo, or product packaging, when online sellers use your trademarks in product listings or domain names, or when businesses adopt similar marks that could confuse customers about the source of goods or services. The document is also essential when you find counterfeit products bearing your trademark or when former employees or business partners continue using your marks after termination of their relationship with your company. Time is critical in trademark enforcement, so you should act quickly upon discovering any unauthorized use.

Key legal considerations

Your warning letter must clearly establish your trademark rights by including registration numbers, classes of protection, and the specific scope of your rights. You need to provide detailed evidence of the infringement, including specific examples, dates, and locations where the unauthorized use occurred. The letter should demand immediate cessation of all infringing activities and require the recipient to sign a declaration of abstention (Unterlassungserklärung), which is a legally binding promise to stop the infringing behavior. Consider including a demand for damages if the infringement has caused financial harm, and set a reasonable deadline for response, typically 7-14 days. Be aware that sending an unjustified warning letter can result in liability for damages, so ensure your claims are well-founded before sending.

Legal requirements in Germany

Under the Markengesetz (German Trademark Act), particularly Sections 14 and 19, trademark owners have exclusive rights to use their marks and can prevent unauthorized use that causes confusion. Your warning letter must comply with German civil procedure requirements and should reference relevant provisions of the Markengesetz, Bürgerliches Gesetzbuch (Civil Code), and potentially the UWG (Unfair Competition Act) if applicable. The letter should be sent by registered mail or through a legal representative to ensure proper documentation. German courts expect trademark owners to attempt resolution through warning letters before seeking injunctive relief, making this document essential for any subsequent legal proceedings. Include your complete contact information and business registration details, and ensure all claims are supported by concrete evidence to avoid potential counterclaims for unjustified threats.
