What this deadline was

Response to the post-registration office action

When: The office action itself states the response period and the date it runs from. It issues against a maintenance filing — a Section 8, 9, 15 or 71 — rather than against an application.
If it is missed: The maintenance filing it relates to can be refused, which puts the registration itself at risk.

How post-registration maintenance works

General information about USPTO practice, not legal advice. The register is the authority, and a filing that has not yet posted can change what is owed.
