Running a Full Trademark Clearance Search: A Practitioner's Guide to Screening, Analysis, and the Written Opinion
By Casey Scott McKay ·
This is the working protocol for clearing a trademark, from the intake call to the signed opinion letter, carried through one annotated matter over seventeen days. It covers fixing the mark and the identification before any search runs, building the phonetic, translation, truncation, and structural variant set, running a ninety-minute knockout screen, sweeping the common-law sources federal databases never touch, and writing a search request a vendor can actually execute. It supplies a five-axis hit-triage rubric that sorts references into fatal, negotiable, and noise, with override rules for the cases where the score lies, and it works through use investigations, including what to instruct an investigator and where Model Rules 4.1, 4.2, and 5.3 stop you. It then gives model language for every section of the opinion letter: scope, summary conclusion, landscape, per-reference risk assessment, risk rating, recommendations, assumptions, caveats, and the conflicts disclosure. It closes with privilege and file hygiene, post-opinion moves, a cost-and-timeline table, and a protocol for the client who wants clearance by Thursday.
