When and How to Send a Cease and Desist Letter

TL;DR: A cease and desist letter is a formal notice demanding that someone stop infringing on your intellectual property rights, whether that involves a trademark, copyright, or patent. Before sending one, document the infringement, gather supporting evidence, and consult an IP lawyer. The letter should identify your rights, describe the violation, state clear demands, and outline consequences for non-compliance.

Intellectual property rights protect the value behind your brand, creative work, or invention. When someone else uses that property without permission, a cease and desist letter is often the first formal step toward resolving the issue. It puts the infringing party on notice, creates a documented record of the dispute, and can prevent the need for costly litigation down the line.

Knowing when to send a cease and desist letter, and how to write one that holds up, can make a significant difference in protecting your intellectual property rights. The intellectual property attorneys at Emerson Thomson Bennett can explain.

When Should You Send a Cease and Desist Letter?

A cease and desist letter may be appropriate when you have a good-faith basis to believe that your intellectual property rights are being infringed. Before sending one, however, it is important to evaluate the strength of your rights, the alleged infringement, potential defenses, and the legal and strategic consequences of making a formal demand. Three common scenarios involve trademarks, copyrights, and patents:

1. Trademark Infringement

Trademark infringement can occur when someone uses a mark in commerce in a way that is likely to cause confusion about the source, sponsorship, affiliation, or approval of goods or services. If unauthorized use threatens your trademark rights, a cease and desist letter may be used to identify the disputed use and demand that it stop.

2. Copyright Infringement

Copyright infringement happens when someone uses your copyrighted material, such as written content, images, music, or software, without your permission. This doesn’t require the violation to completely use or copy the original material. A partial infringement of the copyrighted material can be responded to with a cease and desist. Common examples of this can be found in YouTube videos and video game mods.

3. Patent Infringement

Patent infringement can occur when someone, without authorization, makes, uses, offers to sell, sells, or imports a patented invention in the United States during the term of the patent. Because determining infringement requires analyzing the specific claims of a patent and the accused product or process, potential patent disputes often require careful legal review before a cease and desist letter is sent.

How Do You Send a Cease and Desist Letter?

Sending an effective cease and desist letter involves more than writing a strongly worded email. Following these steps can strengthen your position and reduce legal risk.

Step 1: Establish the Infringement

Start by clearly identifying which specific intellectual property rights are being violated. Pinpoint the exact trademark, copyrighted work, or patent claim in question.

Step 2: Gather Evidence

Collect documentation that supports your infringement claim. This might include screenshots, sales records, registration certificates, or side-by-side comparisons of the original and infringing material.

Step 3: Consult an IP Lawyer

An IP lawyer can validate your claims, confirm the strength of your rights, and help you avoid overreaching demands that could weaken your position if the dispute escalates.

What Should Your Cease and Desist Letter Include?

A well-drafted cease and desist letter typically includes the following elements:

• Identification of your IP rights: Reference relevant registration numbers or ownership documentation.
• Detailed description of the infringement: Explain specifically how the recipient is using your intellectual property.
• Specific demands: State exactly what actions the recipient must stop.
• Clear deadline: Give a defined timeframe for compliance.
• Consequences of non-compliance: Outline the potential legal action you may pursue if the demands are not met.

What Is the Best Way to Deliver a Cease and Desist Letter?

The delivery method you choose can affect both the impact of your letter and your ability to prove it was received.

• Certified mail: Provides documented proof of delivery, which is valuable if the dispute proceeds to litigation.
• Email: Allows for immediate communication and can be useful when time is a factor.
• In-person delivery: Appropriate in certain business relationships where direct contact is expected.

Frequently Asked Questions

What happens if the recipient ignores a cease and desist letter?

If the recipient does not comply, the sender may pursue further legal action, which can include filing a lawsuit for damages or seeking an injunction to stop the infringing activity.

Do I need a lawyer to send a cease and desist letter?

While it is possible to send one without legal help, consulting an IP lawyer first helps confirm your claims are valid and helps you avoid mistakes that could hurt your case later.

Is a cease and desist letter legally binding?

No. A cease and desist letter is not legally binding on its own. It is a formal warning that often precedes legal action if the infringing party does not comply.

How long should the recipient be given to respond?

There is no fixed rule, but deadlines typically range from a few days to a few weeks, depending on the severity of the infringement and the sender’s goals.
