Dead / Void — Void — serial number assigned in error (as of 06 Oct 2026)
What this means for you
This serial number is void: the USPTO assigned it in error because the filing did not meet the minimum filing-date requirements, so it never became an application and blocks no one. The name may be available, but check before relying on it — rights can also come from actual use, not only from the register.
