How much does a patent cost has no single answer, but it has a structure. The cost falls into four buckets, and one of them dominates.
| Bucket | Typical share |
|---|---|
| Attorney drafting | Largest single component |
| USPTO fees | Small, and reducible by 60-80% |
| Office action responses | Varies with technology |
| Maintenance fees over 20 years | Comparable to the whole prosecution |
The headline number. A US utility patent typically costs $8,000 to $20,000 to obtain, and a further $2,894 to $14,470 in USPTO maintenance fees to keep alive for its full term.
USPTO fees: the smallest part
These are fixed, published, and cut sharply by entity status.
| Fee | Large entity | Small entity | Micro entity |
|---|---|---|---|
| Provisional application | ~$300 | ~$120 | ~$60 |
| Utility filing (basic) | ~$350 | ~$140 | ~$70 |
| Search fee | ~$770 | ~$308 | ~$154 |
| Examination fee | ~$880 | ~$352 | ~$176 |
| Subtotal to file | ~$2,000 | ~$800 | ~$400 |
| Issue fee | ~$1,200 | ~$480 | ~$240 |
| Excess claims (over 20) | ~$100 each | ~$40 | ~$20 |
| Excess independent claims (over 3) | ~$480 each | ~$192 | ~$96 |
Fee amounts are revised periodically; check the current schedule before relying on any figure.
Entity status is the largest single lever on official fees. Small entity requires fewer than 500 employees and no assignment to a large entity. Micro entity requires small entity status plus fewer than five prior non-provisional applications plus gross income below roughly $251,190.
Claim count matters more than people expect. A standard filing includes 20 claims with 3 independent. Every claim beyond that carries a fee, and a 40-claim application with 6 independent claims adds meaningfully to the filing cost before any attorney time.
Attorney fees: where the money goes
This is the dominant cost and the one that varies most.
| Service | Typical range |
|---|---|
| Provisional preparation, minimal | $500 - $1,500 |
| Provisional preparation, properly drafted | $2,500 - $5,000 |
| Utility application drafting | $5,000 - $15,000 |
| Office action response | $1,500 - $4,000 each |
| Examiner interview | $500 - $1,500 |
| Appeal to the PTAB | $5,000 - $15,000+ |
Drafting is where the value is created. The claims determine what the patent covers, and a claim set that is easy to design around protects nothing. This is the one place where paying less reliably costs more.
Technology drives the range. Mechanical inventions are cheapest to draft. Software and business methods cost more, largely because subject-matter eligibility rejections under section 101 require multiple rounds of response. Biotechnology and pharmaceutical applications cost most, with complex claim sets and extensive data requirements.
Office actions are the unpredictable part. Most applications receive at least one and two is common. An application that draws four responses costs $6,000 to $16,000 more than one allowed on the first action, and you cannot know which you have until it happens.
Maintenance fees: the cost after grant
Three payments, at 3.5, 7.5 and 11.5 years after grant. Design and plant patents require none.
| Fee | Due at | Large entity | Small entity | Micro entity |
|---|---|---|---|---|
| First | 3.5 years | $2,150 | $860 | $430 |
| Second | 7.5 years | $4,040 | $1,616 | $808 |
| Third | 11.5 years | $8,280 | $3,312 | $1,656 |
| Total | $14,470 | $5,788 | $2,894 |
The escalation is deliberate. The third payment is nearly four times the first, and it exists to force owners who no longer value a patent to release it rather than hold it cheaply for two decades.
It works. Only 41.4% of US utility patents granted in 2014 reached full term. The other 58.6% were abandoned at a fee deadline. Full figures by grant year are on the Ipiry Patent Survival Curve.
You cannot prepay. Each fee is payable only during its own window, so the cost recurs three times across twelve years and each occasion is a fresh decision.
Three worked totals
A solo inventor, micro entity, simple mechanical invention
| Item | Cost |
|---|---|
| Provisional, properly drafted | $2,500 |
| Utility application drafting | $6,000 |
| USPTO filing fees (micro) | $400 |
| One office action response | $2,000 |
| Issue fee (micro) | $240 |
| Total to grant | $11,140 |
| Maintenance fees, all three (micro) | $2,894 |
| Total over the patent's life | $14,034 |
Roughly $14,000 across twenty years for a granted, fully maintained US patent. That is the realistic floor for professionally prepared protection.
A startup, small entity, software invention
| Item | Cost |
|---|---|
| Utility application drafting | $12,000 |
| USPTO filing fees (small) | $800 |
| Three office action responses, §101 issues | $9,000 |
| One examiner interview | $1,000 |
| Request for Continued Examination | $700 |
| Issue fee (small) | $480 |
| Total to grant | $23,980 |
| Maintenance fees, all three (small) | $5,788 |
| Total over the patent's life | $29,768 |
Software costs more because of section 101. Subject-matter eligibility rejections are difficult to overcome by argument and frequently require several rounds, each one billable.
A company, large entity, with foreign protection
| Item | Cost |
|---|---|
| US utility application to grant | $25,000 |
| PCT application | $5,000 |
| National phase: Europe | $12,000 |
| National phase: China | $6,000 |
| National phase: Japan | $8,000 |
| Total to grant, four jurisdictions | $56,000 |
| US maintenance fees | $14,470 |
| European annuities to full term | $25,000+ |
| Chinese and Japanese annuities | $15,000+ |
| Total over the family's life | $110,000+ |
Foreign protection is where budgets break. The US patent is often the cheapest member of a family, and European annuities in particular escalate sharply in later years.
This is why portfolios are pruned country by country. Maintaining protection in markets where you do not sell is a substantial and avoidable cost — see patent portfolio pruning.
Design patents cost much less
| Utility patent | Design patent | |
|---|---|---|
| Protects | How it works | How it looks |
| Term | 20 years from filing | 15 years from grant |
| Drafting | Complex claim negotiation | Drawings, one claim |
| Office actions | Common | Less common |
| Maintenance fees | $2,894 - $14,470 | None |
| Typical total cost | $8,000 - $20,000+ | Low thousands |
No maintenance fees at all is the significant difference over the long run. A design patent granted today costs nothing further for its entire fifteen-year term.
The protection is narrower. A design patent covers ornamental appearance, not function. A competitor who changes the look while keeping the function does not infringe.
Where to reduce cost sensibly
Claim micro entity status if you qualify. An 80% reduction on every USPTO fee across the patent's life. The tests are specific and worth checking properly.
Use a patent agent rather than an attorney for prosecution alone. Agents are registered before the USPTO and typically charge less. You need an attorney for contracts, ownership questions and enforcement advice.
File a well-drafted provisional first. It defers the main cost by twelve months while establishing a priority date, which is useful if funding or market validation is uncertain.
Reduce claim count. Twenty claims with three independent avoids excess claim fees entirely, and a focused claim set is frequently better than a broad one.
File in fewer countries. The most effective saving available. Most inventions are commercially relevant in one or two markets, and filing everywhere by default is expensive insurance against an outcome that rarely occurs.
Respond to office actions within three months. Extensions cost fees and also reduce Patent Term Adjustment day for day, which is a cost that appears at the end of the patent's life rather than on an invoice.
Where not to reduce cost
Drafting. The claims are the patent. A cheap application that issues with claims a competitor can design around in an afternoon has spent everything and bought nothing.
The provisional, if you rely on it. A provisional must enable the invention to provide priority. A two-page description filed to establish a date does not support claims drafted twelve months later, and the priority claim fails exactly when it matters.
Freedom to operate, if you are launching a product. Patent costs are about obtaining rights. Infringing someone else's patent is a different and much larger number — see freedom to operate.
Is it worth it?
The question is whether anyone would practise the invention.
A patent covering something a competitor wants to build is worth many times its cost. A patent covering something nobody makes has option value, and option value declines as term runs down.
58.6% of US utility patents are abandoned before full term, which is a large population of owners concluding, at a fee deadline, that the answer was no. That is not failure — it is the system working, and the escalating fee schedule exists to force exactly that reassessment.
The decision recurs three times. At each maintenance fee window the question is whether the next four years of exclusivity is worth the fee in front of you.
And there is a third option most owners never consider. A patent worth less than its fee to you may be worth something to someone else. Both lapsing and selling end the fee obligation; only one pays you. See patent valuation for how that is assessed, and patents for sale for how the market works.
Before you commit to filing
- Check whether you qualify as a micro entity — it cuts USPTO fees by 80%.
- Get quotes for drafting specifically, not a bundled figure, because that is where the variation is.
- Budget for two office actions, not zero.
- Decide which countries matter before filing, not at national phase entry.
- Model the twenty-year total, including maintenance fees, not just the cost to grant.
- Ask whether anyone would practise the invention, because that is what determines whether any of it was worth spending.
