What this generator produces

It writes a formal infringement demand letter addressed to a person or company you name, on the basis of either a trademark or a copyright. You fill in the mark or the work, the infringing use, the remedy you want and the deadline, and the page assembles a complete letter in plain text. A preview tab shows it as it will read; a text tab exposes the same content for editing.

The letter follows a standard demand-letter shape: your details at the top, the date, a certified-mail line, the recipient block, a subject line identifying the type of infringement, a statement of ownership, a description of the unauthorised use, a legal assertion, a numbered demand with a deadline, and a signature. It is a template for a first written demand, not a court filing, not a takedown notice under any platform's process, and not legal advice.

Trademark or copyright

The radio button at the top controls which description field is used and which words appear in the body.

• Trademark requires the mark or brand name. The subject line reads CEASE AND DESIST – TRADEMARK INFRINGEMENT, and the body refers to "our trademark" followed by your mark in quotation marks.
• Copyright requires a description of the work — a title, a short description, or a URL where the original lives. The subject line reads CEASE AND DESIST – COPYRIGHT INFRINGEMENT, and the body refers to "our copyrighted work" followed by your description.

Switching the type hides the irrelevant field but does not clear it, so you can move between the two without losing what you typed. The registration number and first-use fields are shared: a copyright registration number works there just as a trademark registration does, and the label on the printed letter stays generic.

One tip from the code: the trademark field is already wrapped in quotation marks in the output. Type GlideSkate, not "GlideSkate", or the letter will print doubled quotes.

The parts of the letter

1. Letterhead. Your name or company, then your contact block if you supplied one, then the date.
2. Delivery line. "VIA CERTIFIED MAIL" is written in by default. If you plan to send by email or through a platform, edit that line in the text tab.
3. Recipient. The infringer's name and, if given, the address block including website or email on following lines.
4. Subject. The RE line naming the type of infringement.
5. Salutation. Fixed as "Dear Sir or Madam:" because the form collects a company or individual name but not a contact person.
6. Ownership. A sentence identifying the mark or work, an optional registration sentence, and an optional first-use or publication date.
7. The infringing use. Your own description, inserted verbatim as its own paragraph. This is the part that carries the facts, so it deserves the most care.
8. Legal assertion. A statement that the use constitutes infringement, with optional sentences about counterfeiting, bad faith and dilution.
9. Prior notice. Included only if you describe earlier warnings.
10. Demand. The action you require and the deadline, stated as "within 10 days of your receipt of this letter" or whatever period you choose, plus a request for written confirmation of compliance.
11. Attorney copy. A sentence noting that counsel has been copied, if you tick that option and name them.
12. Governing law. Included only if you supply a jurisdiction, with a reservation of remedies including injunctive relief, damages and fees.
13. Additional notes. Included only if you fill the field.
14. Signature. "Sincerely," followed by your owner name. There is no separate title or signature-line block.

Demands and deadlines

The demand selector offers four prepared actions and a custom option: cease all use, remove infringing content from websites and social media, transfer the domain name to you, or provide a full accounting of profits. Choosing Custom reveals a text field; leaving it empty falls back to "comply with the demands outlined below", which is a weak sentence to send, so write something specific.

The deadline offers seven, ten, fourteen or thirty days, with ten selected by default, plus a custom field such as "five business days". The number you pick is inserted literally, so a custom phrase works naturally in the sentence.

How the advanced options actually behave

Because the dilution wording appears in the standard assertion, a trademark letter always mentions dilution even if you untick the box. If you do not want to allege dilution at all, untick it and edit that sentence in the text tab before sending.

Using the page

1. Choose trademark or copyright.
2. Name the mark or describe the work. Add a registration number and first-use date if you have them; both are optional but they strengthen the letter.
3. Enter the infringer's name and, if you know it, their address, website or email.
4. Describe the infringing use factually. Include product names, page URLs, marketplace listings, dates and screenshots references. Vague descriptions make a demand easy to ignore.
5. Pick the demand and the deadline.
6. Fill in your own name or company and contact details.
7. Open Advanced options for dilution, counterfeiting, bad faith, prior notice, jurisdiction, counsel and extra notes.
8. Check the date, which defaults to today.
9. Press Generate. The preview and text tabs fill in, and validation tells you which required field is missing if something is blank.
10. Read the whole letter in the text tab, edit anything that does not fit, then copy it or download cease-desist-ip.txt.

The Sample button loads a worked trademark example: a fictional skateboard brand sending a letter to a competitor, with a registration number, prior email warning, California jurisdiction, copied counsel and an extra demand. It is the fastest way to see how the optional parts stack up, and it is safe to generate because nothing leaves the browser.

Before you send it

• Confirm you own the right. A demand from someone without a valid claim invites a counterclaim.
• Check the registration number. A wrong number undermines the whole letter.
• Make the facts specific. Name the product, the page and the date. Attach evidence separately; the letter itself carries no attachments.
• Match the demand to the remedy you actually want. A demand to transfer a domain is a different ask from a demand to remove a listing.
• Keep the deadline realistic. Seven days is aggressive; thirty reads as reasonable and is harder to portray as harassment.
• Decide about the dilution, counterfeit and bad-faith sentences. Each one escalates the tone and each one needs a basis.
• Send it in a way that proves receipt. Certified mail with a return receipt, or a platform's official notice channel, and keep the proof.
• Consider an attorney. For a high-value mark, a letter on counsel's letterhead carries more weight and reduces the risk of an ill-judged threat.
• Do not threaten what you will not do. Every remedy mentioned should be one you are prepared to pursue.

What it is not

The letter contains no statutory citations, no case law and no jurisdiction-specific language. It is not a DMCA takedown notice, not a court complaint, not a settlement agreement and not a substitute for a lawyer's letter. It does not file anything, does not serve the recipient, does not track delivery, does not attach evidence and does not send email. There is no template for a reply, no counter-notice and no escalation path.

Limits

One recipient per letter, English only, plain text output, no PDF and no letterhead graphics. There is no field for a contact person at the recipient, no CC list, no second signatory and no reference-number field. Parties outside the United States can use it, but the phrasing — certified mail, statutory damages, attorneys' fees — is written from a US perspective, so review it against local requirements before sending.

Privacy

Everything happens in the browser. Names, addresses, registration numbers and the description of the dispute are never posted to a server, and the download is assembled locally. That makes the page safe for real details, but the file you save and the letter you send are ordinary documents and should be handled as confidential.

Common mistakes

• Adding your own quotation marks around a trademark. The template adds them, so the letter shows doubled quotes.
• Leaving the custom demand empty. The fallback sentence is vague and weakens the letter.
• Forgetting to untick dilution. It is on by default and the assertion sentence mentions dilution regardless.
• Sending with the certified-mail line when you are emailing. Edit that line in the text tab.
• Assuming a copy-to-attorney tick copies anyone. It only adds a sentence; you still have to send it.
• Treating a generated letter as legal advice. Have a professional review it when the stakes are meaningful.
