A trademark infringement cease and desist letter is a document that tells a person or company to stop infringing on a trademark you own. The letter threatens legal action unless the violator stops using your trademark.

Definition of Trademark Infringement

Trademark infringement means using an identical or similar trademarked name, word, phrase, logo, symbol, design, or image.

What Is a Trademark Infringement Cease and Desist Letter?

A trademark infringement cease and desist letter is a formal written request to stop using a trademark belonging to someone else. The letter typically alleges that the recipient is using the trademark without permission and that this use is infringing upon the trademark owner’s rights. It also demands the recipient stop using the trademark immediately.

Is This Letter Legally Enforceable?

No, a trademark infringement cease and desist letter is not legally enforceable. It only warns the infringer that you will take legal action unless they stop.

For your letter to be effective, you must register your trademark with the US Patent and Trademark Office (USPTO). [1] If you don’t, your letter will be powerless because you don’t have legal rights to the trademark, so the offending party can easily ignore it. However, if it’s already registered, infringement can be easier to enforce if you take legal action due to this mandatory application process.

You can check the Trademark Electronic Search System (TESS) to see if your trademark idea has already been taken. [2]
