How the Section 8 deadline really works
- On-time window: file between the 5th and 6th anniversary of your registration date.
- Grace period: a 6-month grace follows the 6th anniversary, with a per-class late fee.
- The real cliff: the end of grace (~6.5 years) is irreversible — miss it and the registration is cancelled with no revival.
- Later: a combined Section 8 & 9 filing is due between the 9th and 10th anniversary, then every 10 years.
Frequently asked questions
- When is my Section 8 declaration due?
- You must file the Section 8 Declaration of Continued Use between the 5th and 6th anniversary of your registration date. After the 6th anniversary there is a 6-month grace period with a per-class late fee.
- What happens if I miss the Section 8 deadline?
- If you miss the end of the 6-month grace period (about 6.5 years from registration), the registration is cancelled. There is no reinstatement and no revival — you lose the mark and its original priority date, and must re-apply from scratch.
- Is the 6-year anniversary the real deadline?
- No. The 6-year anniversary is the end of the on-time window, but a 6-month grace period (with a late fee per class) follows. The true irreversible cliff is the end of grace, roughly 6.5 years after registration.
- Does the USPTO remind me?
- The USPTO sends a courtesy email reminder, but it explicitly states the reminder is not guaranteed, is not resent if delivery fails, and bounces on stale email addresses. It is your responsibility to track the deadline.
