TRADEMARK INFRINGEMENT WARNING LETTER TEMPLATE FAQ

What is a Trademark Infringement Warning Letter?

A Trademark Infringement Warning Letter is a formal but generally softer written notice that alerts a person or business to potential unauthorized or confusing use of your brand name, logo, or other trademark. It asks them to review their use, consider your rights, and change or stop the use before you take stronger steps.

How is a warning letter different from a cease and desist letter?

A warning letter typically uses a less aggressive tone and may focus on raising concerns, inviting clarification, and requesting voluntary changes. A cease and desist letter is usually firmer, clearly demanding that infringing use stop by a specific deadline and more directly warning of possible legal action if it does not.

When should I use a Trademark Infringement Warning Letter?

Use this letter when you first notice a potentially confusing or unauthorized use of your mark and want to resolve the issue cooperatively. It is especially useful when you are unsure whether the other party is aware of your rights or when you prefer to start with a less confrontational approach.

What should a Trademark Infringement Warning Letter include?

It should identify you and your trademark, briefly describe your rights and how the mark is used, describe the other party’s use that concerns you, explain why this use may cause confusion, and politely request that they review and adjust or stop their use. It should also ask for a written response and reserve all of your rights.

Do I need to prove infringement in the warning letter?

No. The warning letter shares your concerns and puts the other party on notice of your trademark rights. You do not need to provide a complete legal analysis, but you should be specific enough that they understand which mark you own and which uses you are concerned about.
