Key Takeaways
  • A cease and desist letter is a demand, not a court order. Receiving one does not mean you've lost — it means someone is claiming you've infringed their trademark.
  • You have options beyond stopping immediately: negotiate, challenge the validity of their mark, argue no likelihood of confusion, or do nothing (accepting the risk).
  • Ignoring a C&D is a decision, not a non-response. The sender can escalate to federal court — and your delay may be used against you.
  • The most dangerous thing you can do is respond emotionally or aggressively without legal advice. A poorly written response can waive defenses and create admissions.
  • If you receive one, the first step is always the same: do not respond immediately, do not panic, and find an IP attorney.

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 Options — There Are More Than You Think

1. Comply Fully

If the claim appears valid — if there's a clear likelihood of confusion and their mark is properly registered and used — compliance may be the fastest and cheapest path. Rebranding is disruptive and costs real money, but defending a losing case costs far more. An honest assessment of your position matters here.

2. Negotiate

Most trademark disputes settle without litigation. If you have some but not all the defenses they claim, or if you operate in a different geographic market or product category, there may be a negotiated outcome — a coexistence agreement, a license, a modification of your mark, or a phaseout timeline. Large companies often prefer a negotiated resolution to the cost and uncertainty of litigation.

3. Challenge the Claim

If you have genuine defenses, you can respond through an attorney asserting them. Common defenses include:

  • No likelihood of confusion — the marks are not similar enough, or the goods/services are too different, for consumers to confuse the two
  • Prior use — you were using the mark before the claimant, establishing superior common law rights (especially in a geographic area)
  • Invalidity of their mark — the registered mark is descriptive, generic, abandoned, or was fraudulently obtained
  • Fair use — you're using the term descriptively, not as a brand identifier
  • Acquiescence or laches — they knew about your use for years and did nothing

4. File a Declaratory Judgment Action

If a company is threatening to sue you and you believe you have strong defenses, you can beat them to court by filing a declaratory judgment action — asking a federal court to rule that you are not infringing. This is an aggressive move that forces the dispute into litigation, but it lets you choose the venue (which can matter a great deal in trademark cases).

5. Do Nothing

You can ignore the letter, but understand what you're choosing. The sender will either escalate (file suit) or not. If they file suit and you've been operating for months after receiving the C&D, your delay will be used to argue willful infringement — which can mean treble damages and attorney fee awards. "Do nothing" is rarely the right choice unless you've concluded the claim has no merit and the sender is unlikely to litigate.

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

Do I have to comply with a cease and desist letter?

No — a C&D letter is not a court order, and you cannot be held in contempt for ignoring one. However, ignoring it carries risk: the sender can escalate to a federal lawsuit, and your failure to respond may be used as evidence of willful infringement, which increases potential damages. The question isn't whether you're legally required to comply, but what the strategic consequences of non-compliance are.

What if the cease and desist letter is wrong or based on a bad faith claim?

This happens more than people realize. Some large companies send C&D letters for marks they don't actually have superior rights to, hoping recipients will comply without investigating. If you believe the claim is invalid — because their mark is descriptive, abandoned, or doesn't actually conflict with yours — an IP attorney can respond asserting those defenses. In egregious cases of bad faith trademark enforcement, you may have counterclaims available.

How much does it cost to respond to a cease and desist?

An attorney review and response to a C&D typically costs $500–$2,000 depending on complexity. A negotiated settlement might add another $2,000–$10,000 in attorney time. Full litigation starts at $50,000–$100,000 per side and can reach several hundred thousand dollars. The C&D response stage is always the cheapest point in the dispute to resolve it.

Can I send a cease and desist letter myself to protect my trademark?

Yes, and many trademark owners do. A C&D doesn't have to come from an attorney to be legally effective. However, an attorney-drafted letter is more likely to be taken seriously, is less likely to contain legally problematic statements, and demonstrates you have counsel prepared to litigate if necessary. For significant disputes, attorney involvement in drafting the initial C&D is usually worth the cost.
