When to Use

A cease and desist letter is delivered to the offender before legal action is taken. It notifies the recipient that they are infringing on the sender’s intellectual property rights and will face a lawsuit if they don’t stop immediately.

Depending on the jurisdiction, sending a cease and desist may be required as evidence that the IP owner tried to settle the matter outside of court. Delivering a notice also helps prove that the infringer is aware of their misappropriation.

Proof of Intellectual Property Theft

The sender will need to be able to demonstrate that they are the rightful owner of the intellectual property concerned.

This evidence may come in the form of:

  • Dated records.
  • Registered patents, trademarks, and designs.
  • Signed NDAs.

Furthermore, if the IP owner sues the letter recipient, they must be able to prove in court that the infringing party misappropriated their property.
