How to draft an intellectual property cease and desist letter with AI
4 min read · Updated May 2026 · Editorial oversight: Avv. Federico Papa
The 'diffida per contraffazione' (cease and desist letter) is the primary extrajudicial tool for protecting industrial property rights. This document serves to formally challenge the infringement of a trademark, patent, or design (e.g., under Arts. 20 or 66 c.p.i.), ordering the alleged infringer to immediately halt harmful activities to avoid judicial proceedings. Its correct formulation is decisive for establishing the counterparty's bad faith and preparing the grounds for potential damage claims under Art. 125 c.p.i. Should the notice be ignored, the document acts as a prerequisite for initiating urgent precautionary procedures such as an injunction (Art. 131 c.p.i.) or seizure (Art. 129 c.p.i.).
In brief
This guide explains how to draft a cease and desist letter with AI, the primary extrajudicial tool for protecting trademark, patent, or design rights under Arts. 20 or 66 c.p.i. This document orders the immediate halt of infringing activities and establishes bad faith for damage claims under Art. 125 c.p.i. The owner must specify registration with UIBM or EUIPO and demand accounting data under Art. 121-bis c.p.i. Failure to comply within 7-15 days supports urgent precautionary measures like injunctions under Art. 131 or seizures under Art. 129.
The steps
- 1.
Precise identification of the IP right and ownership
The first step involves analytically indicating the industrial property right allegedly infringed, specifying the registration number, filing date, and issuing authority (UIBM or EUIPO). It is necessary to demonstrate the sender's full ownership of the right, providing proof of the title's current validity and its territorial scope. A generic description of the intellectual property right deprives the notice of its necessary enforcement power and could prevent the subsequent recognition of the counterparty's intent or negligence.
- 2.
Detailing the infringing conduct and evidence
The contested conduct must be described with technical accuracy, indicating which specific products, services, or distinctive signs constitute infringement in violation of the owner's exclusive rights (e.g., Arts. 20 or 66 c.p.i.). It is fundamental to reference documentary or digital evidence held by the owner, such as website screenshots, catalogs, purchase invoices, or test purchase reports. The challenge must be precise to leave no doubt regarding the identity of the counterfeit goods and the distribution channels used by the recipient.
- 3.
Drafting the order and cease and desist command
The document must contain an explicit order to immediately cease all production, marketing, and advertising of the infringing products. Beyond cessation, the permanent withdrawal from the market of already distributed goods and the destruction of advertising materials or molds used for counterfeiting must be requested. This section must be drafted using imperative terms to clearly manifest the intent to stop the infringement of the proprietary right without further delay.
- 4.
Request for information and accounting under Art. 121-bis c.p.i.
In accordance with the principle of transparency and for damage quantification, the infringer must be asked to communicate data regarding the extent of the violation. Specifically, the disclosure of production quantities, suppliers, customers, and sales prices applied must be demanded to determine the unlawfully realized profit. This request is based on the right of information under Art. 121-bis c.p.i. and is preliminary to a claim for damages or the disgorgement of profits as provided for by Art. 125 c.p.i. in judicial proceedings.
- 5.
Setting the deadline and legal warning
A peremptory deadline, usually between 7 and 15 days, must be assigned to the recipient to comply with the requests and provide a written response. It is essential to include a warning that, failing compliance, actions to protect rights in precautionary proceedings will be initiated without further notice. Explicit reference to Art. 131 c.p.i. for an injunction and Art. 129 c.p.i. for the seizure of assets serves to foreshadow the request for urgent measures before the Specialized Business Courts.
Legal basis: art. 121-bis c.p.i.art. 124 c.p.i.art. 125 c.p.i.art. 129 c.p.i.art. 131 c.p.i.

The standard sections that make up the document. The full template can be opened and completed directly on edit.legal.
Sender
Full identification of the IP right holder and the legal counsel authorized by proxy who signs the document.
Recipient
Details of the alleged infringer, whether manufacturer, distributor, or retailer, to whom the notice is addressed.
IP Right and ownership
Specification of the trademark, patent, or design asserted with the relevant registration details and proof of ownership.
Premises: the contested conduct
Analytical description of the detected violation, the products involved, sales channels, and acquired evidence.
Cease and Desist notice
Formal order to cease the infringement, withdraw products, provide accounting data, and pay damages within a deadline.
Reserves, date, and signature
Reserve to pursue precautionary actions under Arts. 129 and 131 c.p.i., indication of place, date, counsel's signature, and list of attachments.
Mistakes to avoid
- Uncertainty in identifying the IP title, which may render the notice void due to vagueness of the subject matter.
- Failure to attach or indicate the legal counsel's power of attorney, exposing the document to challenges regarding standing.
- Omission of the request for accounting under Art. 121-bis c.p.i., limiting the ability to correctly quantify damages later.
- Use of non-legally traceable delivery methods, such as standard email, which prevent proof of receipt and formal notice of default.
Frequently asked questions
Is a cease and desist letter mandatory before filing an application for urgent interim relief?
It is not legally mandatory, but it is highly recommended to demonstrate the infringer's bad faith and to attempt a swift out-of-court resolution. Furthermore, the recipient's silence following the notice strengthens the periculum in mora (danger in delay) required to obtain precautionary measures under Arts. 129 and 131 c.p.i.
What is the minimum deadline to be granted in the notice?
The law does not fix a rigid deadline, but legal practice suggests between 7 and 15 days to allow for a technical evaluation of the challenge. Terms that are too short might be considered contrary to principles of fairness, while terms that are too long might weaken the perceived urgency of the precautionary action.
What happens if the infringer ignores the notice?
The IP right holder can immediately proceed with a petition for description, seizure, or a precautionary injunction before the Specialized Business Court. Sending the notice without response documents the persistence of the infringement and justifies the request for legal costs and damages under Art. 125 c.p.i.
