Responding to a Cease-and-Desist Letter
By Casey Scott McKay ·
A cease-and-desist letter is an offer of free information disguised as a threat, and this guide is the working manual for taking the information without taking the deal. It runs the full recipient-side sequence in twelve numbered stages: the six things to do in the first forty-eight hours, how to buy time with a holding letter that does not concede anything, how to audit the sender's registration and file wrapper before you audit your own conduct, how to score the confusion claim and build the defense ledger, and how to price a rebrand against a fight so the client decides with a number instead of a feeling. It treats the declaratory-judgment fork under MedImmune, Inc. v. Genentech, Inc., 549 U.S. 118 (2007) and the first-to-file exceptions as a real strategic option rather than a bluff, and explains when a TTAB counterstrike helps and when B&B Hardware makes it a trap. You get model language for the holding letter, the information request, the short representation letter, and every section of a substantive rebuttal, plus a cost-and-timeline table for all six roads out and a five-question decision tree for the fork that matters. A single annotated example — a Providence cookware company against a Charlotte hearth manufacturer with an incontestable registration — runs from the day the letter arrives to the signed agreement, and the guide closes with what to do when they sue you mid-negotiation, take your listings down, or turn out to be right.

Summary. A cease-and-desist letter is an offer of free information disguised as a threat, and this guide is the working manual for taking the information without taking the deal.
