Should You Send a Trademark Cease and Desist Letter First?

A trademark cease and desist letter costs a fraction of a lawsuit and ends a surprising number of disputes in a week. It also hands the recipient a choice you did not intend to give: stop, negotiate, ignore you, or sue you first in a courthouse of their choosing. Before any letter leaves our trademark enforcement team, we ask whether the sender’s position is strong enough to survive each of those responses.

The letter is a tool, not a reflex. Here is how to decide whether to use it, what to put in it, and what to do when you are the one holding it.

What a trademark cease and desist letter is meant to do

A well-drafted letter does four things. It puts the recipient on notice of your rights, which matters later if you need to show willful infringement. It describes the conduct you object to with enough precision that the recipient knows what to change. It states what you want: stop using the mark, withdraw an application, transfer a domain, rebrand within a set period. And it sets a deadline for a response.

What it cannot do is force anything. A letter has exactly as much power as the lawsuit or TTAB filing behind it. If you would never actually sue, the recipient will often figure that out.

Check your own position before anything goes out

The recipient’s first move will be to look up your registration and look for weaknesses. So you should do that first. Confirm the registration is live and your Section 8 filings are current. Confirm that you used the mark before the recipient did; if they have priority, your letter is an invitation to a cancellation petition against you. Run the likelihood of confusion factors honestly: similarity of the marks, relatedness of the goods, trade channels, consumer sophistication, strength of your mark, any actual confusion. A letter that overstates a weak claim reads as a bluff, and bluffs get called.

If you have not registered, you still have common-law rights in the area where you use the mark, but the letter will be weaker and the recipient may race to file its own application. Our trademark search and clearance team can map the competing rights before you commit.

The risks a letter creates

Three deserve a paragraph each.

Declaratory judgment. A letter that threatens litigation can create an actual controversy, which lets the recipient file suit first asking a court to declare that it does not infringe. You then litigate in their home district, on their timeline. Softer language reduces this risk but also reduces the letter’s force; the balance depends on who the recipient is.

Counterattack. A recipient with resources will scrutinize your registration for a cancellation ground: nonuse on some listed goods, an overbroad identification, a specimen problem, abandonment of a product line. If they find one, you may end up defending your registration instead of enforcing it. We explain those grounds in our post on trademark cancellation proceedings.

Publicity. Letters to small businesses and individuals sometimes end up online. A heavy-handed demand against a sympathetic recipient can cost more in reputation than the infringement was costing in sales. Tone matters.

What to put in the letter and what to leave out

Include your registration numbers, the goods and services covered, the date of first use, a plain description of the recipient’s use, and a specific list of what you are asking for and by when. Offer a path out: a phase-out period, a coexistence agreement limited to certain goods, or a license if that fits your business. Reserve your rights.

Leave out threats you will not carry out, claims to rights you do not have, and anything that reads as a demand for money unsupported by facts. Do not attach a draft complaint unless you are prepared to file it. And set a realistic deadline; a two-week response window is common, and one that is too short signals impatience rather than strength.

When to skip the letter and file instead

Some situations call for a filing without warning. If a conflicting application has published and the opposition deadline is close, file the notice of opposition or an extension first and negotiate after; the process is described in our guide on opposing a trademark application. If the recipient is selling counterfeits, a letter only tells them to move inventory, and a platform takedown or a federal counterfeiting claim is the right opening. If the recipient has ignored two prior letters, a third will not work. For copyright and trade secret disputes, where the calculus differs, see when to send a cease and desist for infringement. And if a domain name is the problem, a UDRP complaint may be faster than correspondence, a point we cover in how a UDRP complaint recovers a domain name.

If you are the one who received the letter

Do not ignore it, and do not respond the same day. Calendar the deadline. Check whether the sender actually owns what it claims: the registration number, its status, the listed goods, and the sender’s first-use date versus yours. Look for the weaknesses described above, because they are your defenses. Then decide whether to comply, negotiate a narrower outcome, or push back. Many disputes settle with a coexistence agreement or a modest change to a logo or product description that costs far less than either side’s litigation budget.

If the letter threatens a lawsuit and the sender’s claim is weak, filing your own declaratory judgment action can take control of the forum. That is a serious step and one to take with counsel from our IP litigation and dispute resolution group.
