If counsel represents sender, include firm and bar contact block. | | 2 | **Rights basis** | *Registered*: mark, USPTO number, filing/registration date, classes, goods/services, channels, territory. *Common-law*: first-use date, continuous use, promotion, goodwill, distinctiveness. | | 3 | **Infringing acts** | Fact-based timeline; tie each instance to date, location, and evidence exhibit. | | 4 | **Legal analysis** | Likelihood of confusion under 15 U.S.C. § 1125(a) [VERIFY]: similarity, relatedness, channels, consumer sophistication, intent, actual confusion. Add dilution under 15 U.S.C. § 1125(c) [VERIFY] only if mark qualifies as famous. | | 5 | **Demands** | Permanent cessation across all channels (packaging, web, social, domains, marketplaces, email, advertising). 10–15 business-day cure window unless user specifies otherwise. | | 6 | **Remedies warning** | Injunctive relief (15 U.S.C. § 1116 [VERIFY]), damages/profits/fees (15 U.S.C. § 1117(a) [VERIFY]), and reservation of all rights. | | 7 | **Response mechanics** | Deadline, contact method, required documents: written cure confirmation, removal screenshots, destruction certificate, distributor notices, revenue/unit-sales accounting for infringing period. | ## Drafting Rules 1. Use only verified facts; no vague threats or unsupported conclusions. 2. Tone: firm, professional. No coercive, extortionate, or inflammatory language. 3. **Registered marks**: cite constructive-notice presumptions and class-specific scope [VERIFY]. 4. **Unregistered marks**: establish secondary meaning, source identification, geographic continuity. 5. Preemptively rebut apparent defenses (descriptive fair use, nominative use, prior use, geographic limits) with evidence-based reasoning when facts support it. 6. Include governing-law clause; flag cross-border complexity and advise local counsel for foreign use [VERIFY]. ## Common Pitfalls - **Omitting exhibit references** — every infringement allegation must cite specific evidence. - **Claiming dilution for non-famous marks** — dilution requires fame; omit if not established. - **Vague demands** — specify exact channels, formats, and proof required for compliance. - **Missing accounting demand** — always require written revenue/profit accounting for the infringing period. - **Temporary language** — all demands must be permanent, not temporary.
