Cease And Desist Letter Trademark Infringement Template for the United States

A cease and desist letter for trademark infringement is your first line of defense when someone is unlawfully using your protected trademark. This formal legal document puts the infringer on notice of your trademark rights and demands they immediately stop their unauthorized use. Under United States law, sending this letter demonstrates your active protection of trademark rights, which is crucial for maintaining and enforcing your intellectual property.

When do you need this document?

You need a trademark infringement cease and desist letter when you discover someone using your registered or common law trademark without permission. This includes situations where competitors are using confusingly similar marks, counterfeiters are selling goods with your trademark, online sellers are using your brand name, or companies are using your trademark in their domain names or advertising. The letter is particularly important when the infringement could cause consumer confusion or dilute your brand's distinctiveness. You should send this letter as soon as you become aware of the infringement, as delays in enforcement can weaken your trademark rights and potentially be seen as acquiescence to the unauthorized use.

Key legal considerations

Your cease and desist letter must clearly establish your trademark ownership through registration numbers, filing dates, and evidence of use in commerce. You need to provide specific details about how the recipient is infringing your mark, including exact descriptions of their unauthorized use, locations where the infringement occurs, and any evidence such as screenshots or product samples. The letter should demand immediate cessation of all infringing activities and may request additional remedies such as destruction of infringing materials, accounting of profits, or domain name transfer. Include a reasonable deadline for compliance, typically 10-30 days, and clearly state the legal consequences of non-compliance, including potential litigation and monetary damages. Be careful to avoid making false claims or threats, as this could expose you to claims of trademark misuse or unfair business practices.

Legal requirements in United States

Under the Lanham Act, trademark owners have both the right and obligation to police their marks against infringement. Your letter must comply with federal trademark law while clearly stating your ownership rights and the basis for your infringement claim. Include your trademark registration certificate number and registration date, or if claiming common law rights, provide evidence of first use in commerce and geographic scope of use. The letter should reference relevant federal statutes including the Lanham Act, Federal Trademark Dilution Act, and potentially the Trademark Counterfeiting Act if counterfeiting is involved. For domain name infringement, you may also invoke the Anti-cybersquatting Consumer Protection Act. Ensure your demands are legally justified and proportionate to the infringement, as overly broad or unjustified demands could result in a declaratory judgment action against you. Consider consulting with a trademark attorney to ensure your letter complies with all federal and state requirements and maximizes your chances of successful resolution.
