Understanding your situation
What you need to prepare
- ✓Your trademark registration certificate (or documentation of common law trademark rights)
- ✓Registration number, filing date, and goods/services classes covered
- ✓Evidence of the infringing use - screenshots, photos, URLs, advertising materials
- ✓Description of how the infringing use causes market confusion
- ✓Evidence of your mark's market presence - years of use, marketing investment
- ✓The infringer's full business name and address
- ✓Any prior correspondence with the infringer about the mark
Registered vs unregistered trademark rights: two paths, two enforcement toolkits
In the United States, trademark rights arise from USE in commerce, not from registration. Federal registration under the Lanham Act (15 U.S.C. 1051 et seq.) is a powerful enhancement (nationwide constructive notice, presumption of validity, ability to recover statutory damages for counterfeiting, right to use the Registered symbol) but not a prerequisite for enforcement. Common law trademark rights protect unregistered marks WITHIN the geographic area of actual use, and Section 43(a) of the Lanham Act (15 U.S.C. 1125(a)) provides federal cause of action for unregistered marks against confusingly similar use.
The strategic implication for cease and desist letters: registered marks get nationwide leverage, statutory damages options in counterfeiting cases (up to $2,000,000 per counterfeit mark per type of goods), and stronger presumptions in litigation. Unregistered marks remain enforceable but limited to the geographic area of use, without statutory damages, and requiring proof of secondary meaning for descriptive marks. Before sending a trademark cease and desist letter, verify your registration status: federal registration number, filing date, goods and services classes covered, and any Section 15 incontestability declaration. For unregistered rights, document first use with contemporaneous evidence: dated marketing materials, invoices, packaging, website archives. In the UK, registration under the Trade Marks Act 1994 is generally required for meaningful enforcement (passing off provides a common law alternative but requires proof of goodwill and misrepresentation).
UDRP: the fast track for domain-name trademark disputes
Domain-name disputes involving trademarks have a specialised fast-track resolution mechanism outside of federal court: the Uniform Domain-Name Dispute Resolution Policy (UDRP) administered by ICANN. UDRP complaints are filed with an approved dispute resolution provider (WIPO, Forum, or a small number of others), cost approximately $1,500 in filing fees for a single-panelist proceeding (or $4,000 for a three-panelist proceeding), and typically resolve within 60 days. The remedy is transfer or cancellation of the domain, not damages.
To succeed in a UDRP proceeding, the complainant must establish three elements: (1) the domain name is identical or confusingly similar to a trademark in which the complainant has rights; (2) the current registrant has no rights or legitimate interests in the domain; and (3) the domain was registered and is being used in bad faith. Bad faith is often shown by pattern registration of trademark-similar domains, sale offers to the trademark owner, use for confusion or diversion of the trademark owner's customers, or use for cybersquatting. Where UDRP is not available (some ccTLDs) or where the complainant seeks damages, the US Anticybersquatting Consumer Protection Act (ACPA, 15 U.S.C. 1125(d)) provides federal court remedies including statutory damages of $1,000 to $100,000 per domain name.

CEASE AND DESIST NOTICE - TRADEMARK INFRINGEMENT
FROM: [YOUR COMPANY LEGAL NAME]
ADDRESS: [YOUR COMPANY ADDRESS OR ATTORNEY ADDRESS FOR SERVICE]
DATE: [TODAY'S DATE]
TO: [INFRINGER FULL LEGAL NAME / BUSINESS NAME]
ADDRESS: [BEST KNOWN ADDRESS]
FORMAL DEMAND TO CEASE AND DESIST TRADEMARK INFRINGEMENT
[YOUR COMPANY LEGAL NAME] ("Complainant") is the owner of the following trademark rights:
MARK: [MARK AS USED, e.g. "ACME PRO"]
Registration status:
[If registered:] United States Patent and Trademark Office Registration Number [REG NUMBER], filed [FILING DATE], registered [REGISTRATION DATE], goods and services covered in International Classes [CLASSES].
[If UK/EU:] [UK Intellectual Property Office / EUIPO] Registration Number [REG NUMBER], filed [FILING DATE].
[If common law only:] Continuously used in commerce since [DATE OF FIRST USE] in connection with [GOODS OR SERVICES] in [GEOGRAPHIC AREA OF USE]. Evidence of use includes [MARKETING MATERIALS, INVOICES, WEBSITE ARCHIVES with dates].
INFRINGING USE:
You are currently using the following mark in a manner that infringes Complainant's trademark rights:
Your mark: [INFRINGING MARK AS USED BY THE INFRINGER]
Where used: [SPECIFIC LOCATIONS: business name, logo, website URL, product packaging, social media handles, domain names]
Evidence: [ATTACH OR REFERENCE screenshots, URLs, photographs of infringing product or signage, dates of first observed use]
Likelihood of confusion:
Your use of [YOUR INFRINGING MARK] is confusingly similar to Complainant's registered/common law mark [YOUR MARK] because:
(a) The marks are [identical / nearly identical / phonetically similar / visually similar / share dominant features]; and
(b) The goods or services are [identical / directly competing / closely related / in overlapping channels of trade]; and
(c) Consumers are likely to believe your goods or services are affiliated with, sponsored by, or authorised by Complainant.
APPLICABLE LEGAL FRAMEWORK:
Your conduct constitutes trademark infringement under [SELECT AND CITE]:
- Section 32 of the Lanham Act (15 U.S.C. 1114) for infringement of registered marks
- Section 43(a) of the Lanham Act (15 U.S.C. 1125(a)) for infringement of unregistered marks and trade dress
- Section 43(c) of the Lanham Act (15 U.S.C. 1125(c)) for dilution of famous marks
- [State trademark statutes as applicable]
- [UK Trade Marks Act 1994 sections 10, 11 for UK marks]
- [EU Trade Mark Regulation 2017/1001 for EU marks]
Available remedies include injunctive relief, actual damages, disgorgement of the infringer's profits, treble damages for willful infringement, and attorney fees in exceptional cases.
DEMANDS:
You must, within [14] days of receipt of this letter:
1. CEASE all use of [INFRINGING MARK] or any confusingly similar mark in connection with [SPECIFIC GOODS OR SERVICES].
2. REMOVE all uses from your website, social media accounts, printed materials, product packaging, signage, and advertising.
3. TRANSFER any domain names incorporating [MARK] to Complainant or cancel their registration.
4. DESTROY or return to Complainant any remaining infringing materials.
5. PROVIDE written confirmation of compliance to the address above.
CONSEQUENCES OF NON-COMPLIANCE:
If you fail to cease and confirm within the deadline, Complainant will pursue any or all of:
- Civil action in federal court under the Lanham Act for injunctive relief, damages, disgorgement of profits, and attorney fees where warranted.
- For domain name disputes: UDRP complaint through ICANN-approved provider, or action under the Anticybersquatting Consumer Protection Act (15 U.S.C. 1125(d)) with statutory damages of $1,000 to $100,000 per domain.
- Notification to relevant online platforms and marketplaces (Amazon Brand Registry, eBay VeRO, Shopify Brand Protection, social media trademark reporting).
- Notification to USPTO, EUIPO, or UKIPO opposition proceedings if you have pending trademark applications.
This letter converts any further infringement from potentially innocent to demonstrably willful, which significantly increases available damages under 15 U.S.C. 1117.

Insight from DocuGov: the laches trap that quietly weakens trademark rights
DocuGov.ai
Research-based insight
Adam here, senior legal expert at DocuGov.ai. Trademark law imposes a DUTY TO POLICE your mark. Delay in enforcement against known infringers can weaken your trademark rights over time through two doctrines: laches (equitable defense based on unreasonable delay causing prejudice to the defendant) and acquiescence (implied consent to the use). Courts have denied injunctive relief against long-established infringers where the trademark owner knew of the infringement for years without acting. The Federal Circuit and multiple regional circuits have applied laches to bar trademark claims where the delay exceeds the analogous state statute of limitations (typically 3 to 6 years) and the defendant has invested substantially in the infringing use during the delay.
The practical implication: keep a log of every discovery of potential infringement with the date discovered. If you decide not to pursue immediately (small infringer, unclear jurisdiction, cost-benefit calculation), document the reason. When you do act, act on ALL known infringements consistently: selective enforcement can be argued as inconsistent policing. Send cease and desist letters as soon as reasonably feasible, and where the infringer refuses to stop, escalate promptly. Silence is not neutrality in trademark law; it is a slow surrender of rights.
Frequently Asked Questions
What is a trademark cease and desist letter?
A trademark cease and desist letter is a formal written demand from the owner of a trademark (or their attorney) to a party using the mark or a confusingly similar mark without authorisation. It identifies the trademark rights, describes the infringing use, cites the applicable statute (typically Lanham Act sections 32 or 43(a) in the US, Trade Marks Act 1994 in the UK), and demands cessation, removal of infringing materials, and written confirmation of compliance. It is the standard first step in trademark enforcement.
Do I need a registered trademark to send a cease and desist letter?
No. In the United States, trademark rights arise from use in commerce, not registration. Common law trademark rights protect unregistered marks within the geographic area of actual use. Section 43(a) of the Lanham Act (15 U.S.C. 1125(a)) provides federal cause of action for unregistered marks. However, federal registration significantly enhances your position: nationwide constructive notice, presumption of validity, availability of statutory damages for counterfeiting, and use of the Registered symbol. If you are not registered, document your first use date with contemporaneous evidence.
What is likelihood of confusion in trademark law?
Likelihood of confusion is the central test for trademark infringement. Courts weigh multiple factors (in the US, most circuits use variants of the Polaroid factors from the Second Circuit or the DuPont factors from the Federal Circuit): (1) strength of the mark; (2) similarity of the marks in sight, sound, and meaning; (3) similarity of goods or services; (4) similarity of channels of trade and customers; (5) evidence of actual confusion; (6) the defendant's intent; (7) sophistication of the buyers; (8) likelihood of bridging the gap into the plaintiff's product line. No single factor is dispositive; the analysis is holistic.
What is trademark dilution?
Trademark dilution is harm to the distinctiveness of a famous mark, even in the absence of consumer confusion. Under Section 43(c) of the Lanham Act (15 U.S.C. 1125(c)), owners of famous marks can sue for dilution by blurring (use that weakens the mark's distinctiveness, such as 'Kodak Pianos' for a piano brand) or dilution by tarnishment (use that harms the mark's reputation, often through association with inferior or unsavoury goods). Dilution protection requires the mark to be famous, meaning widely recognised by the general consuming public throughout the United States.
What is a UDRP complaint and when should I use it?
The Uniform Domain-Name Dispute Resolution Policy (UDRP) is a fast-track mechanism administered by ICANN for resolving domain-name disputes involving trademarks. UDRP complaints are filed with providers like WIPO or Forum, cost approximately $1,500 for a single-panelist proceeding, and typically resolve within 60 days. Remedy is transfer or cancellation of the domain, not damages. Use UDRP when: the infringer is a cybersquatter or opportunistic registrant; the domain is registered and used in bad faith; speed matters; damages are not a priority. Use federal court under the Anticybersquatting Consumer Protection Act (15 U.S.C. 1125(d)) instead when you need damages of up to $100,000 per domain.
What if the infringer ignores my trademark cease and desist letter?
Escalate promptly. Options include: federal court action under the Lanham Act for injunctive relief, actual damages, disgorgement of the infringer's profits, and in exceptional cases attorney fees; UDRP or ACPA proceedings for domain names; notification to online marketplaces (Amazon Brand Registry, eBay VeRO) for takedown; notification to social media platforms for handle takedown under their trademark policies; opposition proceedings at the USPTO if the infringer has pending trademark applications. Delay after the cease and desist letter can also strengthen a willfulness argument, potentially trebling damages under 15 U.S.C. 1117.
What is the risk of NOT enforcing my trademark?
Trademark law imposes a duty to police your mark. Failure to enforce against known infringers can weaken your rights through two doctrines: laches (equitable defense based on unreasonable delay causing prejudice to the defendant) and acquiescence (implied consent to the use). Courts have denied injunctive relief against long-established infringers where the trademark owner knew of infringement for years without acting. Delay is not neutrality in trademark law; it is a slow surrender of rights. Keep a log of infringements you discover and act on them consistently.
Can I sue for trademark infringement in state court?
Yes. Federal court has original jurisdiction over Lanham Act claims but is not exclusive; state courts share jurisdiction over most federal trademark claims and have exclusive jurisdiction over state trademark statutes and common law claims. Practical considerations: federal court is often preferred for national brands because of nationwide service of process and the availability of federal rules; state court may be faster and cheaper for regional disputes. Many trademark suits raise both federal and state claims and are typically filed in federal court under supplemental jurisdiction.
