Step One: Don't Panic — And Don't Reply Immediately
The letter is designed to feel urgent and authoritative. It will often reference federal law, use the words "immediate cessation," and imply that failure to comply will result in serious legal consequences. That framing is deliberate. Before you do anything — before you reply, before you call the sender's lawyer, before you tell your team — take 48 hours to understand what you're actually dealing with.
A cease and desist letter has no legal force on its own. It is a private communication from one party to another. Receiving one does not mean you have infringed. It does not mean you've lost. It does not mean you're facing a lawsuit. It means someone believes they have trademark rights that your use may be infringing, and they are putting you on notice of that belief before escalating to litigation.
Important: Do not send an emotional reply, do not call the sending attorney to argue, and do not post about it publicly. Anything you say can be used as evidence if the dispute escalates to litigation. Write nothing you wouldn't want a federal judge to read.
Step Two: Verify the Sender's Trademark Rights
Before evaluating your options, confirm that the sender actually has enforceable trademark rights. C&D letters are sometimes sent on the basis of:
- Expired registrations — the mark lapsed due to missed maintenance filings
- Abandoned applications — the sender applied but never completed registration
- Pending applications — the mark is applied for but not yet registered (limited enforcement rights)
- Weak marks — descriptive or generic terms that may not qualify for protection at all
- Overreaching claims — the registered mark covers different goods/services than what they're claiming against you
Search the USPTO database (or tmarkmetric) for the mark cited in the letter. Check its status: is it live or dead? When was it registered? What goods and services does it cover? Is the coverage actually relevant to what you're doing?
You're looking for weaknesses in their position — not to be combative, but to understand whether you have a legitimate dispute or a straightforward infringement situation. The answer shapes which of the five options below makes the most sense.
Your Five Options
Option 1: Comply Fully
If the sender has a strong, registered trademark in your class, and your use does genuinely create a likelihood of consumer confusion, complying may be the fastest and cheapest path. Rebrand, stop the infringing use by the deadline, and respond to confirm you've done so. Many C&D situations end here, especially when the infringing party didn't know about the senior mark.
The downside: rebranding has costs. Domain name changes, packaging, marketing materials, customer notification. For a small business with minimal investment in the name, this may be a fast fix. For a company with years of brand equity, it's a significant business decision.
Option 2: Negotiate a Coexistence Agreement
If the marks are similar but the goods and services are genuinely different — or if you operate in different geographic markets — a coexistence agreement is sometimes possible. Both parties agree in writing that they can each use their mark under defined conditions (specific classes, geographic territories, distinguishing language).
This requires good faith on both sides and usually involves attorneys. But it can preserve your brand while resolving the conflict without litigation. It's particularly worth pursuing when both marks have been in the market for a while and consumer confusion hasn't actually materialized.
Option 3: Challenge Their Rights
If your research reveals weaknesses in the sender's trademark rights — the mark is descriptive and they lack acquired distinctiveness, or the registration has lapsed, or they're overreaching their registered coverage — you can respond by disputing the basis of their demand.
This response must be carefully drafted by a trademark attorney. A well-argued challenge letter explains why you believe you are not infringing and why their rights may be limited or invalid. If you have your own trademark application or registration, this is where you assert it. The goal is to make the sender's cost-benefit calculation for litigation unfavorable — if they know they'll have to defend their mark's validity in court, many will stand down.
Option 4: Proactive Rebrand While Disputing
A hybrid approach: acknowledge the letter, indicate you are evaluating your options, and begin a rebrand on your own timeline without admitting liability. This buys you time and demonstrates good faith while protecting your business operations. It does not prevent the sender from filing suit, but it often reduces the urgency from their side.
Option 5: Do Nothing (Accept the Risk)
Some businesses calculate that the sender is unlikely to escalate — the potential damages are too low, the mark is too weak, or the sender lacks the resources for litigation. This is a conscious business risk decision, not a mistake. If you choose this path, document your reasoning.
Be aware: doing nothing after a C&D means you can no longer claim innocent infringement if the case goes to court. Under the Lanham Act (15 U.S.C. § 1117), courts can award up to three times actual damages for willful infringement. The moment you receive a C&D and continue using the mark, the "willful" argument is available to the opposing party.
The Response Letter
Whatever option you choose, you should send a written response before the deadline. The response should:
- Acknowledge receipt of the letter (this documents the date you received it)
- State your position clearly — whether you're complying, requesting more time, or disputing the claim
- Not contain admissions of infringement
- Not be aggressive or emotional in tone
- Request additional time if you need it to consult an attorney
Most opposing counsel will grant a reasonable extension (2–4 weeks) if you respond promptly and professionally and ask for it. Silence is what triggers escalation.
What Happens If You Ignore It Entirely
The sender's options after sending a C&D without response are: do nothing further, send a follow-up letter, or file a lawsuit. In federal court, the timeline from complaint to trial for trademark cases typically runs 12–24 months. Litigation is expensive for both sides — most trademark disputes settle before trial.
However, if the sender does file suit, your failure to respond to the C&D will be noted. Courts treat it as evidence of willfulness. It also eliminates the goodwill benefit of appearing cooperative, which often helps in settlement negotiations.
Frequently Asked Questions
Do I legally have to respond to a trademark cease and desist?
No. A C&D letter has no legal force — it's not a court order. You are not required by law to respond. But not responding is itself a choice with consequences: it signals to the sender that escalation is necessary, and it eliminates your ability to claim innocent infringement if the dispute goes to court.
Can I send my own cease and desist if I think their mark is invalid?
Not in response to theirs — that would escalate rather than resolve. If you believe you have your own trademark rights that predate theirs, or that their mark is invalid, the proper response is a well-drafted dispute letter through counsel, potentially followed by a cancellation petition at the TTAB if their mark is registered.
How much does it cost to respond to a trademark C&D?
If you respond yourself (rare, and not recommended when the letter comes from a law firm): $0 but high risk. A trademark attorney's response letter typically runs $500–$2,500 depending on complexity and research required. A full dispute response with prior art research can run $2,000–$5,000. Compare that to the cost of rebranding or the cost of litigation before choosing a path.
What if the C&D is from someone with no registered trademark?
Common law trademark rights exist without registration. If someone has been using a mark in commerce before you, they may have enforceable common law rights in their geographic market even without a USPTO registration. However, unregistered rights are limited geographically and harder to enforce. A C&D from an unregistered rights holder is easier to dispute — but still worth taking seriously if they can demonstrate prior use in your market.
