The Lawful Use Requirement: Why the USPTO Refuses Cannabis, Kratom, and Vape Marks
By Casey Scott McKay ·
Federal trademark registration requires use in commerce, and the USPTO has long read that phrase to mean lawful use in commerce — a requirement that appears nowhere in Section 2 of the Lanham Act but decides the fate of thousands of applications every year. This article traces the doctrine from In re Stellar International through the modern cannabis cases, explains the per se violation standard examiners must satisfy under TMEP 907 and 37 C.F.R. 2.69, and shows why the Controlled Substances Act blocks marijuana marks even in states where the business is fully licensed. It then works through the 2018 Farm Bill's 0.3% delta-9 THC line, the FDA's drug-exclusion position that doomed the CW mark in In re Stanley Brothers Social Enterprises, the Ninth Circuit's delta-8 holding in AK Futures v. Boyd Street Distro, and the November 2025 federal redefinition of hemp that resets the entire analysis on November 12, 2026. Kratom, vapes and ENDS, alcohol labeling, firearms, tobacco, and gambling get the same treatment, because the doctrine is one rule applied across a dozen regulatory regimes. The closing sections cover what an applicant actually owns when registration is unavailable — state registrations, common-law rights, and a carefully built ancillary portfolio — and identify the four places where the law is genuinely unresolved.

Summary. Federal registration requires "use in commerce," and for more than half a century the USPTO has read that phrase to mean lawful use in commerce — a requirement found nowhere in Section 2 of the Lanham Act, yet dispositive for thousands of applications a year. This article traces the doctrine from the 1968 Stellar International decision to the modern cannabis cases, explains the per se violation standard an examiner must satisfy under TMEP § 907 and 37 C.F.R. § 2.69, and shows why the Controlled Substances Act defeats a marijuana mark even when the applicant holds every state license. It works through the 2018 Farm Bill's 0.3% delta-9 THC line, the FDA drug-exclusion rule that killed the CW mark in In re Stanley Brothers Social Enterprises, the Ninth Circuit's delta-8 holding in AK Futures v. Boyd Street Distro, and the November 2025 statutory redefinition of hemp that resets everything on November 12, 2026. Kratom, vapes, alcohol, firearms, tobacco, and gambling get the same analysis, because this is one doctrine applied across a dozen regulatory regimes. It closes with what you actually own when registration is off the table, and the four questions the courts have not answered.
