The Quarterly Patent Docketing Audit
4
Checks in a full quarterly pass
15–20
Correspondence items to sample
3
US maintenance fee windows per patent
6
Months of grace before rights lapse
The four checks below are built to run once a quarter by a team of one or two, to keep things running smoothly for years to come. The appendix carries the US maintenance fee windows and a schedule for which checks to run in which quarter.
1. Coverage
0 of 3This check finds assets the docket does not know about.
2. Entry integrity
0 of 3Sampling recent correspondence shows whether action items are becoming entries.
3. Annuity ownership
0 of 3Fees get paid by you, counsel, or a service.
4. Continuity
0 of 3The docket has to keep running when you are out.
Appendix: the deadline calendar
| Payment window (after issue) | Grace period (surcharge applies) | Rights lapse if unpaid by | Large entity | Small entity | Micro entity | Fee code |
|---|---|---|---|---|---|---|
| 3 to 3.5 years | 3.5 to 4 years | End of year 4 | $2,150 | $860 | $430 | 1551 |
| 7 to 7.5 years | 7.5 to 8 years | End of year 8 | $4,040 | $1,616 | $808 | 1552 |
| 11 to 11.5 years | 11.5 to 12 years | End of year 12 | $8,280 | $3,312 | $1,656 | 1553 |
Paying inside the grace period adds a surcharge of $540 for a large entity, $216 small, $108 micro. It is a separate fee code at each stage: 1554 at 3.5 years, 1555 at 7.5, 1556 at 11.5.
Miss the grace period and the patent lapses. Reviving it is a petition rather than a surcharge, and it is granted rather than guaranteed. Fee code 1558 covers a delay of a year or less, at $2,260 large, $904 small, $452 micro. Past a year it is fee code 1560, at $3,000, $1,200, and $600.
Foreign annuities are typically an annual fee keyed to each country's filing or grant anniversary. Each asset carries its own date. Check 3 builds the jurisdiction list that covers them.
What to run each quarter
- First quarter
- Run all four checks at full depth and record asset count, jurisdiction count, and miss rate as your baseline.
- Second quarter
- Run Coverage and Entry integrity in full. Spot check Annuity ownership for anything that changed hands.
- Third quarter
- Run Annuity ownership in full against the written jurisdiction list, and Coverage on everything granted or filed this year.
- Fourth quarter
- Run the Continuity walkthrough with your named cover, and note which patents enter a maintenance fee window next year.

What is a patent docketing audit?
A periodic check that the docket reflects reality, rather than a check of what the docket already contains. Daily docketing verifies entries that exist. An audit looks for the obligation that never became an entry, and therefore never produced a reminder. An asset nobody added, an office action that arrived and was actioned but never docketed, an annuity both you and outside counsel assumed the other was paying.
How often should a small IP team run one?
Once a quarter, at varying depth. Run all four checks in full in the first quarter to set a baseline, then rotate: Coverage and Entry integrity in the second quarter, Annuity ownership in the third, and the Continuity walkthrough in the fourth. A team of one or two can sustain that. A full four-check pass every quarter usually gets skipped by the third one.
When are US patent maintenance fees due?
Three times in a patent’s life, measured from its issue date rather than from a filing date or a common annual date: at 3 to 3.5 years, 7 to 7.5 years, and 11 to 11.5 years. Because each window runs from that patent’s own issue date, due dates spread across the calendar one patent at a time, which is why they cannot be handled as a single annual task.
What happens if you miss a maintenance fee deadline?
There is a six-month grace period after each window in which you can still pay, with a surcharge of $540 for a large entity, $216 small, and $108 micro. Past the grace period the patent lapses. Reviving it requires a petition for delayed payment, which is granted on a showing about the delay rather than automatically. That is fee code 1558 at $2,260 large, $904 small, $452 micro if the delay is a year or less, and fee code 1560 at $3,000, $1,200, and $600 beyond a year.
Who should be responsible for paying annuities?
Whoever it is, the point is that it is written down and confirmed. Fees get paid by you, by outside counsel, or by an annuity service, and the failure mode is not that nobody can pay. It is a handoff where two parties remember the arrangement differently. Get each named payer to confirm in writing once a year, and pay particular attention to any asset that changed hands since the last audit.
What should the docket audit cover for continuity?
Whether the docket survives your absence. Name who covers it if you are out for six weeks and write that name where your manager can find it. Confirm that person can locate the docket, the credentials, and the pending response list without calling you. Once a year, walk them through one live matter end to end. If any of it lives only in your head or your inbox, it is not continuity.
