Status (September 22, 2026): Common-law use of World Dead Hang Championship, WDHC, and Grip Age™ is active on worlddeadhang.com. The owner to name on a future application is World Dead Hang Championship LLC. No USPTO registration number yet. The current base application fee is $350 per class when the application meets USPTO base requirements (2025 fee rule). Extra fees apply for incomplete applications or free-form identifications. Planned path: free USPTO search, then a base application starting with Grip Age (Class 41), then the championship word mark when budget allows. Do not use the (R) symbol until a mark is registered.
