Trademark Infringement Cease and Desist Letter

A trademark cease and desist letter demands that a business or individual stop using a mark—a name, logo, slogan, or other identifier—that infringes on the sender's registered or established trademark. Trademark law protects the distinctive identifiers that consumers use to distinguish goods and services from different sources. When a second user adopts a confusingly similar mark for related goods or services, consumers may be misled about the source, quality, or affiliation of the second user's products—the core harm that trademark law is designed to prevent. The cease and desist letter is the standard opening move in trademark enforcement, giving the infringer an opportunity to resolve the dispute without litigation while establishing the trademark owner's enforcement record.

Federal trademark registration with the U.S. Patent and Trademark Office provides the strongest foundation for a trademark cease and desist letter. Registration creates a legal presumption of ownership and the exclusive right to use the mark nationwide in connection with the registered goods and services. Common law trademark rights—acquired through actual use in commerce without registration—are geographically limited to the area where the mark is actually used and do not carry the same presumptions. A registered trademark owner's cease and desist letter benefits from statutory remedies under the Lanham Act, including the ability to recover actual damages, the infringer's profits, treble damages for willful infringement, and attorney fees in exceptional cases.

The likelihood of confusion analysis is the substantive heart of any trademark infringement claim. Courts evaluate multiple factors to determine whether the infringing mark would likely cause consumers to be confused about the source of goods or services: the similarity of the marks in appearance, sound, and meaning; the similarity of the goods and services; the channels of trade; the strength of the original mark; the sophistication of relevant consumers; and evidence of actual confusion. A cease and desist letter that walks through these factors—demonstrating why the recipient's mark is likely to cause consumer confusion—is more persuasive than a bare assertion of infringement and more accurately previews the legal claim that would be filed if the matter proceeded to litigation.

The scope of trademark protection is limited to the specific goods and services identified in the registration or established through use. A trademark for restaurant services does not automatically extend to clothing merchandise; a trademark for software does not cover all technology products. When sending a cease and desist, confirm that the recipient is using the contested mark in connection with goods or services that overlap with or are related to the trademark owner's registered goods and services. Demanding cessation of uses that are clearly outside the scope of the trademark owner's rights invites a legal challenge to the demand and may constitute trademark misuse or abuse of process.
