# Trademark Cease-and-Desist Letter Pre-suit notice demanding cessation of alleged trademark infringement and evidence preservation. ## Quick Start Collect before drafting: 1. **Owner** — legal name, entity type, signatory, counsel contact 2. **Mark** — exact mark, USPTO registration number/date/class (if any), first-use date 3. **Scope** — goods/services, channels of trade, geography 4. **Infringement evidence** — dated screenshots, URLs, product images, ads, packaging 5. **Confusion evidence** — actual confusion incidents, customer overlap, goods similarity 6. **Demands** — stop use, remove content, destroy inventory, transfer domains/handles, accounting 7. **Deadline** — exact calendar date, delivery method, proof-of-receipt plan ## Workflow ### 1. Gather Inputs | Input | Req? | Notes | |---|---|---| | Owner name + address | Yes | Include counsel if represented | | Mark type (word / design / composite) | Yes | — | | Registration status | No | If registered, include USPTO details | | First-use date | No | Required for common-law claims | | Goods/services description | Yes | Match registered or actual use | | Infringer name + address | Yes | Include DBA, online identifiers | | Infringing uses | Yes | URLs, listings, products, social handles | | Evidence list | Yes | Attach as exhibits | | Demands + deadline | Yes | Exact calendar date | ### 2. Analyze Likelihood of Confusion Address only applicable factors: | Factor | Evidence | |---|---| | Similarity of marks | Appearance, sound, meaning, commercial impression | | Relatedness of goods/services | Overlap or complementarity | | Strength of mark | Distinctiveness, duration, marketing spend | | Channels of trade | Same platforms, retailers, customer base | | Actual confusion | Misdirected inquiries, emails | | Intent | Copying, bad-faith adoption, prior knowledge | | Consumer sophistication | Purchase care level | ### 3. Select Demands | Demand | Include when | Proof requested | |---|---|---| | Immediate cessation | Always | Written confirmation | | Remove from websites/marketplaces | Online use | Takedown screenshots | | Destroy inventory/packaging | Physical goods | Destruction certification | | Transfer domains/handles | Domains/handles used | Transfer confirmation | | Notify distributors/retailers | Third parties involved | Copy of notice | | Accounting of sales/profits | Damages likely | Sales report | ### 4. Draft Letter Structure the letter in this order: 1. **Representation & purpose** — identify client, state formal notice 2. **Rights in the mark** — registered: USPTO Reg. No., date, classes, Lanham Act (15 U.S.C. § 1051 et seq.); unregistered: first-use date, geography, distinctiveness evidence 3. **Infringing use** — identify infringing mark, products/services/platforms, dates observed; assert likelihood of confusion as to source, sponsorship, or affiliation 4. **Likelihood-of-confusion analysis** — concise factor-based summary tied to evidence 5. **Demands** — numbered list of specific actions required 6. **Deadline** — exact compliance date with written confirmation required 7. **Remedies notice** — injunctive relief, damages, disgorgement under 15 U.S.C. § 1117(a) 8. **Reservation of rights** — no license or waiver granted 9. **Response instructions** — where to send response, what to include 10. **Enclosures** — exhibit list ## Pitfalls - Use only verified facts; every allegation must have a supporting exhibit. - Firm and professional tone only — no threats beyond civil remedies. - Never claim willfulness without supporting facts (e.g., prior notice). - Use exact calendar dates for deadlines, not "within X days." - If including settlement terms, frame under FRE 408 and keep separate from demands. - Tailor to jurisdiction — reference applicable state unfair-competition statutes. - Address defenses only when evidence supports rebuttal.
