What changed
The TTAB sustained Ohio State University's opposition to Death-Omen LLC's application to register the single letter 'O' as a trademark. This decision prevents Death-Omen LLC from obtaining federal trademark registration for the contested mark.
Trademark applicants and brand owners should be aware that single-letter marks face heightened scrutiny, particularly when they overlap with established collegiate or institutional branding. Parties seeking registration of simple letter marks should conduct comprehensive clearance searches and be prepared to defend against likelihood-of-confusion challenges from entities with similar established marks.
