How much does a patent cost?
A US utility patent typically costs $10,000 to $25,000 through a traditional law firm. Most of that is attorney time; official USPTO filing fees are $2,000 for large companies, $800 for small entities and $400 for micro entities, plus a $1,290 issue fee at grant and maintenance fees after. Software and deep tech patents sit at the high end of the range.
- USPTO filing, search and examination fees for a utility patent total $2,000 standard, $800 small entity and $400 micro entity under the fee schedule effective 19 January 2025 (source: USPTO fee schedule, last revised 1 June 2026).
- The utility patent issue fee is $1,290 standard, $516 small entity and $258 micro entity (source: USPTO fee schedule).
- Maintenance fees due at 3.5, 7.5 and 11.5 years total $14,470 for a standard entity ($2,150 + $4,040 + $8,280) over a patent's life (source: USPTO fee schedule).
- AIPLA's Report of the Economic Survey puts median attorney charges at roughly $7,500 to draft a minimally complex utility application and $10,000 for a relatively complex one (source: AIPLA, Report of the Economic Survey).
- Small entities pay 60% less and micro entities 80% less on most USPTO patent fees under the Unleashing American Innovators Act of 2022 (source: USPTO).
What a patent really costs
"How much does a patent cost" has two answers, and most pages only give you one. Official USPTO fees are fixed and published. Attorney fees are not, and they make up most of the bill.
For a US utility patent handled by a traditional law firm, budget $10,000 to $25,000 from first draft to grant. Drafting the application typically runs $7,500 to $15,000. Responding to USPTO office actions adds $2,000 to $5,000 per response, and most applications get at least one. Official fees come on top.
Simple mechanical inventions sit at the low end. Software, AI and deep tech inventions sit at the high end, because the claims are harder to draft and examiners push back more often.
USPTO official fees in 2026
These are the government fees under the schedule that took effect on 19 January 2025, last revised 1 June 2026. Small entities (broadly, fewer than 500 employees) pay 60% less than the standard rate. Micro entities pay 80% less.
- Filing, search and examination (due at filing): $2,000 standard, $800 small entity, $400 micro entity
- Provisional application filing: $325 standard, $130 small entity, $65 micro entity
- Issue fee (due at grant): $1,290 standard, $516 small entity, $258 micro entity
- Maintenance fee at 3.5 years: $2,150 standard, $860 small entity, $430 micro entity
- Maintenance fee at 7.5 years: $4,040 standard, $1,616 small entity, $808 micro entity
- Maintenance fee at 11.5 years: $8,280 standard, $3,312 small entity, $1,656 micro entity
Maintenance fees alone total $14,470 for a standard entity over a patent's life. Miss a payment window and the patent lapses.
Attorney fees are where the money goes
Patent attorneys bill roughly $300 to $600 per hour. AIPLA's Report of the Economic Survey puts the median charge for drafting at about $7,500 for a minimally complex application and $10,000 for a relatively complex one. Add prior art searching, filing formalities and prosecution, and the hours stack up.
The structural problem is that hourly billing has no cap. A difficult examiner, a second or third office action, or a continuation filing can push a "roughly $15,000" estimate well past $25,000. You find out the real price at the end, not the start.
What most people get wrong about patent costs
Four mistakes show up again and again:
- Budgeting for filing, not prosecution. The application is the entry ticket. Most applications receive at least one office action, and each response costs $2,000 to $5,000 in attorney time.
- Treating the cheapest draft as the cheapest patent. A $3,000 application with narrow or sloppy claims can grant quickly and protect nothing. Redrafting or refiling costs more than doing it properly once.
- Ignoring maintenance fees. Grant is not the finish line. Standard entities pay another $14,470 over 11.5 years to keep the patent alive.
- Not claiming entity discounts. Most startups qualify as small entities (60% off official fees) and many founders qualify as micro entities (80% off). Plenty pay the standard rate by default.
How Lightbringer handles this
Lightbringer is an AI patent platform built to take the price uncertainty out of filing. You draft with AI assistance, a patent attorney reviews the work, and you pay a fixed, published price per filing instead of an open-ended hourly bill. Official USPTO fees stay the same whoever files; what changes is the attorney-time layer that makes up most of the traditional $10,000 to $25,000.
You see the full cost before you start, not on the final invoice.
FAQ
How much does a provisional patent application cost?
The USPTO filing fee is $325 standard, $130 for small entities and $65 for micro entities. An attorney-drafted provisional typically costs $2,000 to $6,000 on top. It buys you a 12-month priority date but is never examined and never becomes a patent on its own.
How much does it cost to maintain a patent after grant?
US utility patents carry maintenance fees at 3.5, 7.5 and 11.5 years: $2,150, $4,040 and $8,280 for standard entities, totalling $14,470. Small entities pay $5,788 in total and micro entities $2,894. Miss a payment window and the patent lapses.
Can I file a patent myself to save money?
Legally, yes. You would pay only official fees, from $400 for a micro entity. In practice, claim drafting is where patents are won or lost, and errors are hard to fix after filing. Self-filed applications are granted less often and frequently end up with claims too narrow to enforce.
Why do software and AI patents cost more?
The claims must describe technical mechanisms precisely enough to survive eligibility scrutiny under section 101, and examiners reject these applications more often. That means more drafting time and more office action responses, which pushes software patents towards the top of the $10,000 to $25,000 range.
Do I qualify for small or micro entity discounts?
Most startups and individual inventors qualify as small entities (broadly, fewer than 500 employees), which cuts official USPTO fees by 60%. Micro entity status cuts them by 80% but adds limits on income and on how many earlier applications you have filed. Check your status before paying; the discounts are claimed at filing.
