Most portfolios grow by default. Something gets filed, it issues, and from then on the renewal gets paid because nobody wants to be the person who killed a patent. That default is expensive — and it gets more expensive at every renewal window. A disciplined IP portfolio assessment replaces the default with a decision, and the decision is usually worth real money. The hard part isn’t deciding to do one. It’s building a rubric your CFO and your business units will both accept.
An assessment is only as good as the register it is run against. Where that register lives — a spreadsheet, a platform, or an outsourced docket — changes how often you can repeat this exercise; our comparison of IP portfolio management software covers the practical trade-offs.
An assessment tells you what the portfolio contains at a point in time; keeping that picture current is a tooling question, and it is where intellectual property asset management software earns its licence fee.

What an IP Portfolio Assessment Covers
An inventory tells you what you own. An assessment tells you what to do about it. The output isn’t a list of assets — it’s three lists: what you keep funding, what you let go, and what you try to make money from.
Teams typically run one for a specific trigger:
- Annual budget season, when IP spend has to be justified line by line.
- A renewal cliff, when a cohort of patents hits a fee window together.
- A transaction, where a buyer or investor is about to do this analysis for you.
- A strategy shift, when the company exits a product line and the patents around it stop mattering.
The trigger shapes the depth. A budget review can be lighter than transaction diligence — but the rubric should be the same one either way, or the results won’t be comparable year over year.
The Maintenance Fee Math That Forces the Decision
US utility patents carry maintenance fees at three points: 3.5, 7.5, and 11.5 years after issue, under 35 U.S.C. § 41(b) and 37 CFR 1.362. The fees escalate sharply, which is precisely why they function as natural decision gates.
Under the USPTO fee schedule effective January 19, 2025, undiscounted entity amounts are $2,150 at 3.5 years, $4,040 at 7.5 years, and $8,280 at 11.5 years. Small entities pay 60% less and micro entities 80% less — so the same three payments run $860 / $1,616 / $3,312 for a small entity, and $430 / $808 / $1,656 for a micro entity.
Two consequences follow, and both matter more than the individual numbers:
- The back half dominates. Well over half the lifetime US maintenance cost of a patent sits in that final payment. A patent you’re unsure about at 7.5 years is a patent you should be actively deciding about, not renewing reflexively.
- Entity status is money. Claiming small or micro entity status when you no longer qualify creates real exposure, and failing to claim it when you do qualify wastes 60–80% of every fee. Verify status per asset, not per company.
Miss a window and there’s a six-month grace period with a surcharge — $540 undiscounted, $216 small, $108 micro. Design patents, worth noting, carry no US maintenance fees at all, so they don’t belong in this part of the analysis. Current figures are always on the USPTO fee schedule, and foreign annuities follow entirely separate rules that usually dwarf the US numbers.
A Scoring Rubric You Can Actually Defend
Vendor content on this topic tends to list evaluation factors and stop there. Factors without weights just relocate the argument. Score each asset 1–5 on five criteria, weight them, and total:
- Business alignment (weight 3). Does this read on a product you currently sell or plan to? The single strongest predictor of whether an asset is worth keeping.
- Claim strength and scope (weight 3). Would the claims actually stop a competitor, or are they so narrow that designing around is trivial?
- Competitive relevance (weight 2). Is anyone else operating in this space? A patent nobody would ever infringe has little defensive value.
- Licensing or sale potential (weight 2). Is there a market for it outside your own use?
- Cost to maintain (weight 1, inverted). Multi-jurisdiction families with heavy annuities need a higher bar than a single US patent.
Agree the weights before anyone sees a score. Doing it in the other order turns the exercise into advocacy. And record the reasoning in one sentence per asset — a year later, that sentence is the only thing that makes the decision reviewable.
Keep, Prune, or Monetize: The Three Buckets
Scores sort assets into buckets, but the buckets need thresholds set in advance and a genuine escape hatch.
- Keep. High business alignment or high claim strength. Fund without further debate and revisit at the next fee window.
- Monetize. Weak alignment to your business, but real strength or relevance to someone else’s. Sale, license, or contribution to a pool — and note that this bucket has a shelf life, since an asset gets harder to sell as it ages toward the 11.5-year payment.
- Prune. Low on everything. Stop paying and let it lapse.
- Hold for review. The escape hatch. Genuine uncertainty, usually because a product decision is pending. Cap this bucket deliberately, or everything lands in it.
One caution worth stating plainly: pruning is not purely a cost exercise. A patent that looks dead weight against today’s products can matter enormously if you’re later accused of infringement and need something to assert back. Weigh defensive value before you cut, particularly in litigious sectors. Our guide to patent portfolio analysis goes deeper on reading the competitive landscape around your assets.
What Actually Happens When You Let a Patent Lapse
This is the part that makes people hesitate, and it’s usually left out of the guides that recommend pruning. Here’s the mechanism.
Miss a maintenance fee and the patent expires at the end of the grace period. The invention passes into the public domain — anyone can practice it, including the competitors you were worried about. That’s the point of pruning, but it should be a decision made with open eyes.
Revival is possible but not casual. Under 37 CFR 1.378, a patent that expired for non-payment can be reinstated by petition if the delay was unintentional, accompanied by the outstanding fee and a petition fee. Two things follow:
- A deliberate decision not to pay isn’t unintentional. If you pruned on purpose and later change your mind, that route is not designed for you.
- Intervening rights can attach. Third parties who began practicing the invention during the lapse may retain protection even after reinstatement, which can hollow out the patent’s practical value.
So treat pruning as one-way. Which is an argument for the rubric, not against pruning: reversible decisions can be sloppy, irreversible ones need a written rationale.
From a one-off assessment to ongoing IP portfolio management
An assessment is a snapshot; IP portfolio management is what you do with it for the next four years. The rubric above only pays for itself if the keep, prune or monetize call is revisited on a schedule, and most teams tie that schedule to the US maintenance-fee windows at 3.5, 7.5 and 11.5 years — those are the moments the decision actually costs money. Handling IP portfolio assessment and management as one continuous loop, rather than a project that ends when the spreadsheet is delivered, is the difference between pruning deliberately and letting a patent lapse by accident.
Who Should Be in the Room — and When to Run It
An assessment run entirely inside the legal department produces defensible legal scores and poor business scores. IP counsel can judge claim strength; they usually can’t tell you which product line gets discontinued next year.
- IP counsel — claim scope, validity concerns, family structure.
- Product or engineering leads — whether the asset reads on anything real, and whether it still will in two years.
- Finance — the spend forecast and the entity status question.
- An outside searcher or analyst — competitive relevance and licensing potential, where an internal team’s view is naturally inward-looking.
On timing: run the full assessment annually, ahead of budget, and screen the specific cohort hitting a fee window about six months before payment is due. Six months is enough to run a sale process if something lands in the monetize bucket; six weeks is not. If you’re also standing up systems to track all this, the reconciliation work pairs naturally with choosing an IP management system, and annuity and renewal management covers the payment mechanics.
Timing also determines which form of review you need: an annual internal assessment and a transaction-driven investigation answer different questions and produce different deliverables. If you are unsure which applies, see whether your business needs an audit or full diligence.

Turning a One-Off Review into an IP Portfolio Assessment and Management Programme
A single review tells you what the estate looks like today. It does nothing about the fact that the estate changes every quarter — applications publish, claims narrow, products sunset, competitors file, and maintenance windows open and close on their own schedule. The companies that get real value out of this work stop treating it as a project and run IP portfolio assessment and management as a standing process with a calendar, an owner and a budget line.
The practical unit of that process is the annual cycle, anchored to two dates you do not control: the fiscal planning cycle and the renewal calendar. Working backwards from the budget submission gives you roughly a quarter of runway, which is about what a defensible scoring pass over a few hundred assets actually takes once business-unit interviews are included. Anchoring instead to renewal dates — and in the United States that means the 3.5, 7.5 and 11.5-year windows — guarantees that every prune decision arrives before the money has already been committed rather than after.
Who owns the decision
Ownership is where most programmes quietly fail. If the decision sits with IP counsel alone, pruning is systematically under-done, because the downside of abandoning a right that later mattered is visible and personal while the saving is diffuse. If it sits with finance alone, pruning is over-done, because maintenance fees are legible and strategic optionality is not.
The arrangement that works assigns the recommendation to counsel working from the rubric, the veto to the business unit that would have to live without the right, and the decision to a single named executive accountable for both the spend and the coverage. Write that allocation down. Programmes that leave it implicit default to paying every fee, which is the most expensive option available.
Wiring it into the docket
The assessment and the docket have to be the same system of record, or the programme degrades within two cycles. Every scored asset needs its rubric result, the date it was scored, the decision taken and the person who took it stored against the matter itself — not in a spreadsheet that lives on someone’s drive. The reason is mundane and decisive: when the renewal reminder fires eighteen months later, whoever handles it needs to see that the asset was reviewed, scored low, and marked for lapse, otherwise they will pay the fee by default. An assessment whose conclusions are not visible at the moment of payment has no effect on spend.
This is also the point at which tooling starts to matter. Below roughly a hundred assets a well-disciplined spreadsheet plus a competent docketing provider is entirely adequate. Above a few hundred, and particularly across multiple jurisdictions with differing renewal rules, the reconciliation burden between scoring records and renewal records becomes the dominant cost, and a platform that holds both begins to pay for itself.
Metrics that survive a board question
Report the programme on four numbers and resist adding more. Total annual renewal spend, split by jurisdiction, is the cost base. Coverage ratio — the proportion of current revenue-generating products with at least one granted claim reading on them — is the protection measure, and it is the one that stops pruning from going too far. Decision latency, meaning the average gap between an asset being scored and a decision being recorded, measures whether the process is actually running or merely documented. And realised saving against the prior cycle’s baseline is what justifies the next year’s budget.
Deliberately absent from that list is total asset count. It is the number most often reported and the least informative, because it rises with filing activity regardless of whether the filings protect anything that generates revenue. A portfolio that shrinks by fifteen per cent while coverage holds steady is a better portfolio and a cheaper one, and a programme measured on headcount of patents will never produce that outcome.
Mature IP portfolio assessment and management also builds in a deliberate second look. Assets marked for lapse should sit in a review queue for one cycle before the decision becomes irreversible, because the cheapest time to catch a mistake is while the right still exists. Once a US patent has lapsed for non-payment, revival requires showing the delay was unintentional and paying the associated petition fee, and that route is neither automatic nor free. A one-cycle hold costs one more renewal payment on a small number of assets and removes nearly all of the genuine downside risk that makes organisations reluctant to prune in the first place.

Frequently Asked Questions
What is an IP portfolio assessment?
It’s a structured review that scores each asset against business and competitive criteria and sorts the portfolio into keep, prune, and monetize decisions — rather than simply cataloguing what you own.
How often should we run one?
Annually ahead of budget planning, plus a targeted screen of any cohort approaching a maintenance fee window roughly six months before payment is due.
When are US patent maintenance fees due?
At 3.5, 7.5, and 11.5 years after issue for utility patents, under 35 U.S.C. § 41(b). There is a six-month grace period with a surcharge. US design patents carry no maintenance fees.
Can we revive a patent after deciding not to pay?
Only if the delay was unintentional, by petition under 37 CFR 1.378 with the outstanding and petition fees. A deliberate decision to prune does not qualify, and intervening rights may limit the revived patent’s value.
How much can pruning actually save?
It depends on portfolio shape, but because fees escalate steeply toward the 11.5-year payment and foreign annuities compound on top, savings concentrate in older assets. Screening the back half of the portfolio yields the most.
Is pruning risky?
It’s irreversible in practice, so the risk is letting go of something with defensive value you later need. Weighting competitive relevance in the rubric and documenting the rationale for each cut is how you manage that.
Want to Know What Your Portfolio Is Actually Worth?
Reading about portfolio strategy is one thing; knowing which of your own assets carry real coverage and which are renewal costs is another. PerspireIP runs patent portfolio analysis that scores each family for strength and claim coverage, maps it against competitor filings, and flags the gaps and prune candidates — so renewal budget follows the assets that defend revenue.
