Registration starts the maintenance clock: a Section 8 declaration is due between years 5 and 6.
A filing missed by the due date enters a six-month grace period, then the registration cancels.
Recorded as the nightly register update observes them. A cancelled or expired mark no longer blocks a new filing of the same name.
Spellings are merged when they differ only in punctuation or legal suffix. Anything else stays separate rather than guessed.
