Responding to a Trademark Cease-and-Desist Letter
A cease-and-desist letter is alarming, but it is the opening move in a negotiation, not the end of your business. This guide walks you through exactly what to do when one lands in your inbox: how to read it like a lawyer, how to size up the sender's rights and your own using the free public record, and how to choose among the realistic response options, from a short representation letter to a substantive denial to a preemptive declaratory-judgment suit. We explain the governing law in plain English and with primary authority, including likelihood of confusion, descriptive and nominative fair use, incontestability, laches, and abandonment, and show how each plays out through worked hypotheticals. We flag the traps, especially careless admissions and the risk that an aggressive response triggers the very lawsuit you were trying to avoid. The aim is a calm, strategic playbook that a founder, a brand manager, and the lawyer they hire can all follow.
