Patent maintenance: running it as a practice

By Ipiry TeamPublished September 2, 20267 min read

Short answer

Patent maintenance is an administrative practice, not a payment. It needs a named owner, a docket recording both the window opening and the grace period closing, an entity status check at every payment, and a review that reaches the person who knows whether the patent still matters. The failure mode is treating the deadline as an invoice, which produces payment by default on patents nobody would consciously renew.

Patent maintenance is usually described as three payments. Running it well is an administrative practice, and the difference shows up in what happens at each deadline.

A practice has an owner, a docket, a check and a review. Without those, the fee arrives as an invoice and gets paid, or does not arrive and the patent dies.

Both failure modes are common. The second is visible and the first is not — paying by default on patents nobody would consciously renew costs more in aggregate than the occasional accidental lapse.

The four components

Component	Purpose
A named owner	Someone accountable, not a distribution list
A docket	Both dates per patent, at the right rate
An entity status check	At every payment, without exception
A review	Reaching the person who knows if it still matters

All four, or the practice has a gap. A docket without a review produces payment by default; a review without a docket misses deadlines.

The windows

Fee	Window opens	Due	Grace ends
First	3 years after grant	3.5 years	4 years
Second	7 years	7.5 years	8 years
Third	11 years	11.5 years	12 years

Payment cannot be made before the window opens. The dates cannot be brought forward, so the docket has to hold them for years.

The grace period costs a surcharge and provides six months of margin. Record both dates — a docket holding only the due date discards that margin.

After the grace period the patent expires permanently and without notice. See patent maintenance fees.

The amounts

Fee	Large	Small (40%)	Micro (20%)
First	$2,150	$860	$430
Second	$4,040	$1,616	$808
Third	$8,280	$3,312	$1,656
Total	$14,470	$5,788	$2,894

The escalation is deliberate. Each fee is larger and buys a shorter remaining window, which forces re-evaluation three times.

Entity status: check at every payment

The most commonly mishandled part of the practice.

Event	Effect on status
Headcount passes 500	Small entity ends
Licence or assignment to a large entity	Small entity ends
Acquisition	Usually ends it
Fifth non-provisional filed	Micro entity ends
Income rises above the threshold	Micro entity ends
Nothing changed	Still verify and record

Status is a judgement about current circumstances, not a setting recorded at filing. It must be true on the day of each payment.

Underpaying is treated seriously. Claiming a reduced rate without entitlement, particularly where not promptly corrected, can render a patent unenforceable — a far worse outcome than the shortfall itself.

Record the basis, not just the conclusion. A note saying "small entity: 140 employees, no licences to large entities, verified 12 Jan" is checkable years later. See small entity status.

The docket

Field	Why
Patent number and title	Identification
Window opening date	Earliest payment
Grace period closing date	The real deadline
Amount at current entity rate	Budgeting
Named owner	Accountability
Review date, 3 months before grace ends	Forces the decision
Last verified status	Entity check trail

Diarise the review, not just the payment. A calendar entry saying "pay $3,312" produces a payment; one saying "decide: keep, sell, license or lapse" produces a decision.

Route it to a person. A reminder sent to a group address is nobody's responsibility, and that is where lapses originate in organisations that have a docket at all.

Do not rely on USPTO reminders


Courtesy reminder	May be sent
Legally required	No
Non-receipt a basis for reinstatement	No
Reliable for planning	No

The docket must stand alone. Address changes, spam filtering and personnel changes all break external reminders, and none of those excuses a lapse.

Verifying payment

Step	Where
Confirm the payment posted	USPTO Patent Center
Check the amount matches the entity rate	Same
Record the confirmation	Your own file
Spot-check delegated payments	Quarterly

Check the office record, not the confirmation email. A provider's or attorney's confirmation is a report; Patent Center is evidence, and checking takes two minutes.

Spot-check five per quarter where payment is delegated. It catches a systemic problem early and costs almost nothing. See patent annuity payment services.

Making it a decision

Four options at every window, and two happen by default.

Option	Requires action?	Ends the fee?	Pays you?
Pay	No — the default	No	No
Sell	Yes, months ahead	Yes	Yes
License	Yes	No	Yes, ongoing
Lapse	No — the default	Yes	No

The two defaults are the two that produce nothing. Paying costs money; lapsing receives none.

Ipiry Patent Survival Curve v1.0	Rate
Survive the 3.5-year fee (2022 cohort)	85.8%
Survive the 7.5-year fee (2018 cohort)	64.6%
Reach full term (2014 cohort)	41.4%
Abandoned before full term	58.6%
Lost at the third fee	23.2 points

Computed from 27,273,654 USPTO maintenance fee records covering 8,262,336 US utility patents — see the patent survival curve.

Nearly three in five are abandoned, and most of those decisions were made by not acting rather than by deciding. A patent released for nothing at a deadline is the same patent that could have been sold three months earlier.

Worked example: a portfolio review

A company with 34 US patents runs an annual review in January.

Step	Detail
1. List every fee due in the next 18 months	11 patents
2. Verify entity status	Grew past 500 — now large entity
3. Recalculate amounts at the new rate	$14,470 lifetime each, not $5,788
4. Check which claims anyone practises	Cheap search per patent
5. Categorise	Core / defensive / dormant
6. Decide	—

Category	Count	Decision
Core — practised, enforced	4	Pay
Defensive — blocking value	3	Pay
Dormant — nobody practises	4	Sell or lapse


Fees avoided by not renewing 4	~$25,000 over their remaining lives
Sale process started	11 months before the deadlines
Patents sold	2
Patents lapsed deliberately	2

The entity status change was the finding nobody was looking for. Fees had more than doubled and the budget had not been updated.

Starting eleven months ahead is what made the sales possible. A review in the final month would have left paying or lapsing.

Foreign portfolios differ

	US	Most other countries
Frequency	3 fees after grant	Annual
Payable while pending	No	Often yes
Decisions per patent	3	Up to 20
Practical approach	Docket	Annuity service

A foreign portfolio needs a service, not a spreadsheet. Twenty deadlines a year across four jurisdictions is beyond reliable manual tracking. See patent annuity.

Patent maintenance: the checklist

Name one owner. A distribution list is nobody's responsibility.
Docket both dates per patent — window opening and grace period closing.
Never rely on USPTO reminders. They are courtesy, not obligation.
Check entity status at every payment, and record the basis, not just the conclusion.
Recalculate amounts when status changes. Large entity fees are two and a half times small entity.
Diarise a review three months before each grace period closes.
Phrase the entry as a decision, not a payment.
Verify every payment in Patent Center, and spot-check delegated ones quarterly.
Run an annual portfolio review covering the next eighteen months, so selling stays possible.
Use an annuity service for any foreign portfolio, while keeping the renewal decision in-house.

Common questions

Who is responsible for paying maintenance fees?

The patent owner. Anyone may physically make the payment, but the obligation and the consequence sit with the owner. If an attorney or service handles it, that is delegation of execution, not of responsibility.

When can maintenance fees be paid?

In a six-month window before each due date at 3.5, 7.5 and 11.5 years after grant, then in a further six-month grace period with a surcharge. Payment cannot be made early beyond the window opening, so the dates cannot be brought forward.

What should be in the docket?

Both the window opening and the grace period closing, for every patent, with the amount at the correct entity rate. Recording only the due date loses the six months of margin the grace period provides.

Does the USPTO send reminders?

A courtesy reminder may be sent, and it is not a legal requirement and cannot be relied on. Non-receipt is not a basis for reinstatement, so the docket must stand on its own.

How often should entity status be checked?

At every payment. It is a judgement about your current circumstances, not a setting recorded once. Growth past 500 employees or a licence to a large company ends small entity eligibility, and paying at the wrong rate has serious consequences.

What happens if the wrong entity rate is paid?

Underpayment must be corrected. Where a reduced rate is claimed without entitlement, and particularly where the error is not corrected promptly, the patent can be rendered unenforceable. It is treated far more seriously than a simple shortfall.

Can a lapsed patent be revived?

Sometimes, by petition showing the delay was unintentional, with a substantial fee. It is not guaranteed, and intervening rights can arise for parties who began practising the invention during the lapse. Revival is a remedy, not a plan.

Who should receive the reminder?

Someone who can decide, not a distribution list. A reminder routed to a group tends to be nobody's responsibility. One named owner who triages and escalates is what survives a busy quarter.

How far ahead should the review happen?

At least three months before the grace period closes, and ideally a year ahead at portfolio level. Selling a patent takes months, so a review that happens in the final weeks has already eliminated one of the four options.

Should maintenance be outsourced?

Execution can be, and for foreign portfolios it usually should. The decision about which patents to keep cannot be, because it depends on commercial knowledge no external provider has.

How do I verify a payment was actually made?

Check USPTO Patent Center directly. It shows maintenance fee status per patent. A provider's or attorney's confirmation is a report; the office record is evidence, and checking takes a couple of minutes.

What is the most common maintenance failure?

Paying by default. The fee gets paid because it arrived as a deadline rather than as a question, so patents nobody would consciously renew stay in the portfolio absorbing escalating fees for years.
