Preventing Genericide: A Brand Owner's Guide to Trademark Style, Policing, and Primary Significance Evidence
By Casey Scott McKay ·
This guide builds the anti-genericide program a brand owner actually runs, stage by stage, from the day a mark launches through the day a cancellation petition arrives. It covers risk triage across a portfolio, coining the generic noun that competitors will use instead of your mark, drafting and enforcing a trademark style guide, auditing your own back catalog before anyone subpoenas it, binding licensees and co-packers with a usage schedule, and instrumenting monitoring so linguistic drift is caught in year two rather than year twelve. It gives model style-guide rules, a model editorial correction letter, and a full dictionary correction letter outline, along with decision trees for which letter to send and whether to run a survey. It then turns to defense: the first thirty days after a genericness attack, the evidence hierarchy that decides these cases, the Teflon-versus-Thermos choice, and how to attack the challenger's media and dictionary proof. It closes with the mirror image, how to attack a mark as generic through a letter of protest, an opposition, a petition to cancel, or a counterclaim, and what each route costs. The doctrine lives in the companion article; everything here is execution, with realistic timelines, fees, and the traps that cost money.
