What a Cease and Desist Letter Actually Is
A trademark cease and desist letter — sometimes called a C&D — is a formal written demand from a trademark owner (or their attorney) claiming that you are infringing their trademark and demanding that you stop. It will typically identify the trademark being infringed, describe the allegedly infringing conduct, and demand specific actions: stop using the mark, destroy existing inventory, provide an accounting of sales made, and sometimes pay damages.
The crucial thing to understand is what a C&D is not: it is not a lawsuit, it is not a court order, and it is not a final legal determination that you've done anything wrong. It is one party's legal position, stated in the most aggressive terms their attorney can construct. The letter is designed to look conclusive and overwhelming. That is a deliberate strategy.
Receiving a cease and desist letter is not the end of anything. It is the beginning of a negotiation — or, if necessary, a legal dispute — in which you have rights, options, and potentially strong defenses.
Why Companies Send Them
Trademark owners have a legal obligation to police their marks. A trademark that is not actively defended against infringement can be weakened — potentially to the point of becoming unenforceable. Courts have held that a trademark owner who knows about infringement and does nothing risks the defense of "laches" being raised against them later. So large companies in particular send C&D letters proactively, sometimes aggressively, for marks they've only loosely registered.
There's also a practical calculation: a cease and desist letter costs a few hundred dollars in attorney time to draft. A federal lawsuit costs hundreds of thousands. Many trademark disputes end with the C&D — the recipient complies, rebrands, or negotiates a license — and no litigation ever happens. C&D letters are volume tools as much as they are legal weapons.
Reality check: Most cease and desist letters are sent by large companies to small businesses or individuals. The power imbalance is real, and the letters are often written to maximize that perceived imbalance. That doesn't mean the claim is valid. Small businesses with legitimate defenses win trademark disputes regularly — they just need to evaluate their position clearly before responding.
What the Letter Will Claim
A typical trademark C&D makes several assertions:
- That the sender owns a valid registered trademark (they'll cite the registration number)
- That your use of a similar mark in commerce creates a likelihood of confusion with their mark
- That this constitutes trademark infringement under Section 32 of the Lanham Act (if registered) or Section 43(a) (if unregistered)
- That you must immediately cease all use of the infringing mark, destroy inventory and marketing materials, provide a written confirmation of compliance, and sometimes account for profits made
- That failure to comply within a specified deadline (typically 10–30 days) will result in legal action
Your Real Options, Briefly
Once you understand what the letter is actually claiming, the response decision comes down to a handful of paths: comply fully, negotiate a settlement or coexistence agreement, challenge the claim through an attorney if you have genuine defenses (no likelihood of confusion, prior use, an invalid or abandoned mark, fair use, laches), escalate first with a declaratory judgment action, or do nothing and accept the risk of escalation. Which path makes sense depends entirely on the strength of your position — not on how aggressive the letter sounds. For the full walkthrough of each option, the evidence you need to evaluate your position, and how to draft or coordinate a response, see our step-by-step guide to responding to a trademark cease and desist.
What Not to Do
The instinct when receiving a C&D is to respond immediately, emotionally, and at length — explaining your position, asserting your rights, and making arguments. Resist this completely. A written response from you, especially a non-attorney response, can:
- Create admissions that are used against you in later litigation
- Waive defenses you didn't know you had
- Establish a record of willful infringement if any element of your response is wrong
- Start an unfavorable correspondence chain that their attorneys will use to build a case
The standard advice from IP attorneys is consistent: do not respond without counsel. Get an IP attorney to review the C&D, assess your actual position, and draft any response. The cost is almost always less than the cost of an avoidable mistake.
The Timeline That Actually Matters
The deadline in a C&D letter is not a court deadline — it's a demand. Missing it doesn't automatically result in anything other than a potential follow-up. However, sitting on it for months while continuing the allegedly infringing conduct is risky. Courts do factor in how you responded to notice when determining damages.
A reasonable approach: acknowledge receipt briefly (or don't, if your attorney advises silence), consult an IP attorney within the first week, and have a formal response or a compliance/negotiation plan within the stated deadline period if possible. Show that you took the claim seriously even if you dispute it.
Frequently Asked Questions
Is a cease and desist letter the same as being sued?
No. A C&D is a demand letter, not a court filing — nothing has been filed against you, and no judge is involved yet. It's the sender's opening position, stated as forcefully as their attorney can construct it. Whether it turns into a lawsuit depends entirely on how the dispute is handled from here.
Why do companies send cease and desist letters instead of just suing?
Cost and obligation. A C&D costs a few hundred dollars in attorney time; a federal lawsuit costs hundreds of thousands. Trademark owners are also legally expected to police their marks — failing to act against known infringement can support a "laches" defense against them later — so sending letters proactively, even for loosely-held marks, is standard practice rather than a sign the claim is especially strong.
What does a cease and desist letter have to actually claim to be credible?
A properly constructed C&D asserts a specific registered mark (with registration number), a likelihood-of-confusion argument tying your use to theirs, a legal basis (typically the Lanham Act), and a specific demand with a deadline. A letter that's vague about any of these — no registration cited, no clear confusion argument — is weaker than it may sound.
Can I send a cease and desist letter myself to protect my trademark?
Yes. A C&D doesn't have to come from an attorney to be legally effective, though an attorney-drafted letter is taken more seriously and less likely to contain statements that create legal problems for you later.
