PATENT INFRINGEMENT CEASE AND DESIST LETTER TEMPLATE FAQ

What is a Patent Infringement Cease and Desist Letter?

A Patent Infringement Cease and Desist Letter is a formal written notice telling a person or business that their product, process, or technology is infringing a patent and demanding that the unauthorized use stop. It typically identifies the patent, explains how it is being infringed, and lists the actions you want the other party to take.

When should I send a Patent Infringement Cease and Desist Letter?

You usually send this type of letter when you have reason to believe someone is making, using, selling, offering to sell, or importing a product or process covered by your patent without permission. It is often a first step before considering licensing discussions, a settlement, or litigation.

What should a Patent Infringement Cease and Desist Letter include?

A clear letter should identify the patent owner, list the relevant patent(s) and basic details, describe the allegedly infringing product or process, explain in general terms how it falls within the patent claims, demand that the infringing conduct stop, request information or an accounting if appropriate, and set a deadline for response while reserving all rights.

Does a cease and desist letter prove that infringement exists?

No. The letter states your position and concerns, but it is not a court decision. Patent infringement can be complex, and only a court or agreed settlement can resolve disputes definitively. The letter does, however, put the recipient on notice of your patent rights and your objection.

Can I use a cease and desist letter to start licensing discussions?

Yes. Many patent owners use an infringement letter to open a discussion that may lead to a license, design change, or settlement. The letter can invite the other party to discuss options while still clearly demanding that unauthorized use stop if no agreement is reached.
