Answers · Audits & Portfolio Pruning
Which patents should we abandon to cut costs?
Updated June 2026
The short answer
Abandon the patents that fail four tests: no mapping to a current or planned product, no read on a competitor's product, no credible licensing interest, and no coverage of space your market is moving into. A patent that passes even one of the four is usually worth its fees; a patent that fails all four is a pruning candidate.
Published analyses of USPTO data indicate more than half of US patents lapse before their full 20-year term because maintenance fees go unpaid, so pruning is routine portfolio management, not an admission of failure. The discipline is running the tests before each fee decision instead of paying by default.
The pruning screen at each maintenance-fee decision
| If the patent... | Then... |
|---|---|
| Covers a current or roadmap product | Keep and pay. It is doing the protective work you filed it for. |
| Reads on a competitor's product | Keep. It is leverage, and a candidate for licensing or assertion through counsel. |
| Has documented licensing interest or external citations | Keep, and run a monetization screen before the next fee window. |
| Covers space the market is moving into | Keep as option value, and revisit at the next window. |
| Fails all four tests | Offer for sale or license with 6 to 12 months of runway; otherwise lapse deliberately. |
The four-test screen
Product mapping comes first: does at least one claim cover a product you sell today or have on the roadmap? This is the test most portfolios fail quietly, because products move on while patents sit still. Second, competitor relevance: do the claims read on something a competitor ships? A patent can protect nothing of yours and still be your strongest negotiating asset, which is why pruning purely by product mapping destroys value. Third, licensing potential: is there documented external demand, inbound interest, or an adjacent industry practicing the invention? Fourth, white-space value: does the patent cover territory your market is clearly moving toward, where holding the position is worth a few thousand dollars a year of option value?
US maintenance fees come due at 3.5, 7.5, and 11.5 years after grant and roughly double at each stage, which makes those dates natural checkpoints. The third-stage decision deserves the most scrutiny: it is the most expensive fee, paid on the oldest patents, with the least term remaining.
What to do with pruning candidates before you abandon
Letting a patent lapse is free, final, and gives the invention to everyone, so check the exits first. Patents with any external relevance can be offered for sale or license; published broker data suggests most patents that sell at all trade in the five to low six figures per asset, and a brokered sale commonly takes 6 to 12 months, so start well before the fee deadline. Donation rarely pencils out: US tax rules tightened in 2004 limit the deduction and require a qualified appraisal, which makes it a tax-advisor question, not a default.
If no exit materializes, lapse deliberately: decide inside the fee window, document the reasoning, and notify anyone relying on the asset. Reviving a lapsed patent through the USPTO's unintentional-delay process is narrow and uncertain, and it is a matter for your patent counsel, so treat abandonment as permanent.
Run it as a standing process, not a one-time purge
A one-time purge decays immediately, because new fee deadlines arrive every quarter. The companies that keep budgets down run the four-test screen as a calendar-driven process: an annual scoring pass over the whole portfolio, plus a decision gate at every maintenance window. The inputs are a current product-to-patent map, competitor filing data, and forward citations, which is the same data a portfolio audit produces.
In our engagements the pruning conversation works best with R&D, finance, and IP in the same room: R&D knows what the roadmap needs, finance knows what the fees cost, and IP knows which claims read on competitors. We have run this analysis across more than 2,000 engagements since 1998, and the pattern holds at every portfolio size.
Related questions
How much does abandoning a patent actually save?
Under the current USPTO schedule, a large entity pays roughly $2,000 at 3.5 years, roughly double that at 7.5, and roughly $8,000 at 11.5, around $14,000 over a patent's life in US maintenance fees alone. Foreign annuities are often larger in aggregate because most countries charge every year. Pruning one mid-life family with broad foreign coverage can save tens of thousands of dollars.
Can we get a patent back after it lapses?
There is a 6-month grace period with a surcharge, and after that a narrow USPTO petition process for unintentional delay. Neither is a planning tool, and revival is legal work for your patent counsel. Treat a lapse decision as final.
Should we try to sell patents instead of abandoning them?
Try, with realistic expectations. Many patents find no buyer, and those that sell commonly trade in the five to low six figures, with broker commissions commonly running 25 to 35 percent. Start the process at least a year before the fee deadline so a failed sale still leaves a clean lapse decision.
Who should own the abandon decision?
A small cross-functional group: IP, finance, and R&D, with a defined tie-breaker. Letting outside counsel default to paying every fee is the most common way portfolios bloat, because no one is accountable for the carrying cost.
Prune with evidence, not guesswork
We can map your portfolio against products, competitors, and licensing demand so every fee decision has a reason behind it. The discovery call is free.
