A U.S. utility patent generally costs between $10,000 and $25,000 to obtain, with government fees making up a small share and attorney fees the rest; a design patent commonly runs $2,000 to $4,000, and both figures shift substantially depending on whether you qualify as a small or micro entity. So the honest answer to how much a patent costs is that it depends on three things: the type of patent, the complexity of the invention, and your entity size at the USPTO. Once the patent issues, a utility patent also carries up to $14,470 in maintenance fees spread over 20 years; design and plant patents carry none.
What the USPTO Charges
The U.S. Patent and Trademark Office collects fees at three points: when you file, when the patent issues, and at set intervals afterward to keep a utility patent alive. Every fee is tied to your entity size. Large entities (generally companies with 500 or more employees) pay the full rate. Small entities (independent inventors, nonprofits, and businesses with fewer than 500 employees) pay 60% less. Micro entities pay 80% less.1United States Patent and Trademark Office. Micro Entity Status
Filing a non-provisional utility application triggers three fees at once: the basic filing fee, a search fee, and an examination fee. Combined, they total $2,000 for a large entity, $800 for a small entity, and $400 for a micro entity. If the application is allowed, you then pay an issue fee of $1,290, $516, or $258 respectively.2United States Patent and Trademark Office. USPTO Fee Schedule
Add those up and a utility patent’s government fees through issuance run about $3,300 at full price, $1,300 for a small entity, or $660 for a micro entity. That’s the predictable half of the bill.
Attorney and Agent Fees
Professional fees usually cost several times what the USPTO charges. Patent attorneys and agents do the work most inventors can’t do well on their own: searching prior art, drafting claims precise enough to survive examination, and responding to the examiner’s rejections.
A professional prior art search typically runs $1,000 to $3,000, depending on how crowded the technology field is. Drafting the non-provisional application is the single biggest expense, commonly $5,000 to $15,000, and higher for complex fields like biotechnology, medical devices, or software. Each response to an examiner’s Office Action generally costs $1,500 to $4,000, and the average application receives about two Office Actions before it is either allowed or abandoned.
Those numbers explain the $10,000 to $25,000 range. Simple mechanical inventions sit near the low end. Software and pharmaceutical inventions push past $25,000, sometimes well past it.
How Entity Status Changes the Price
The Unleashing American Innovators Act of 2022 expanded the discounts smaller applicants receive. Small entities get 60% off most USPTO patent fees; micro entities get 80% off.3Federal Register. Reducing Patent Fees for Small Entities and Micro Entities Under the Unleashing American Innovators Act The discount applies to filing, searching, examining, issuing, appealing, and maintaining a patent.4Office of the Law Revision Counsel. 35 USC 41 – Patent Fees; Patent and Trademark Search Systems
Small entity status is easy to qualify for: independent inventors, nonprofits, and businesses with under 500 employees. Micro entity status is narrower. You need to meet the small entity criteria, not have been named on more than four previously filed applications, and neither you nor the inventor can have earned more than three times the U.S. median household income the prior year. You also cannot have assigned or licensed the invention to anyone above that income limit.1United States Patent and Trademark Office. Micro Entity Status
These discounts apply only to government fees. Attorney fees are set by the market and don’t change based on entity size.
Utility, Design, and Plant Patents
The three types of U.S. patents carry very different price tags.
Utility Patents
Utility patents protect the functional aspects of an invention: new processes, machines, manufactured articles, and compositions of matter.5Office of the Law Revision Counsel. 35 USC 101 – Inventions Patentable They are the most common type and the most expensive. Total costs from filing through issuance typically run $10,000 to $25,000, with substantial maintenance fees on top over a 20-year life.
Design Patents
Design patents protect the ornamental appearance of an object rather than how it works. The application is simpler, examination is faster, and there’s only one claim. Total costs commonly land between $2,000 and $4,000 depending on entity size, assuming no Office Actions.2United States Patent and Trademark Office. USPTO Fee Schedule Design patents require no maintenance fees at all.6United States Patent and Trademark Office. Manual of Patent Examining Procedure Section 2504 – Patents Subject to Maintenance Fees
Plant Patents
Plant patents cover new and distinct varieties of asexually reproduced plants. Filing and examination fees are slightly lower than utility patents,4Office of the Law Revision Counsel. 35 USC 41 – Patent Fees; Patent and Trademark Search Systems and like design patents, plant patents require no maintenance fees.6United States Patent and Trademark Office. Manual of Patent Examining Procedure Section 2504 – Patents Subject to Maintenance Fees
Provisional Applications: A Cheaper First Step
Many inventors start with a provisional application, which establishes an early filing date and gives you 12 months to file the full non-provisional.7United States Patent and Trademark Office. About Provisional Application for Patent The government fee is $325 for a large entity, $130 for a small entity, or $65 for a micro entity.2United States Patent and Trademark Office. USPTO Fee Schedule Attorney fees are also lower because formal claims aren’t required. A well-prepared provisional typically runs $1,500 to $4,000 in attorney time.
A provisional is never examined and will be abandoned after 12 months unless you file a non-provisional claiming its priority date. It’s essentially a way to buy time to test the market or secure funding before committing to full prosecution costs.
Where Costs Escalate: Office Actions, RCEs, and Appeals
Most applications receive at least one Office Action, which is the examiner’s written explanation of why some or all of your claims are being rejected. Your attorney has to respond with legal arguments and often amended claims. If the examiner issues a final rejection, you have to decide whether to give up, request continued examination, or appeal.
A Request for Continued Examination (RCE) reopens prosecution. The government fee for a first RCE is $1,500 at full price, $600 small, or $300 micro. Second and later RCEs jump to $2,860, $1,144, or $572.2United States Patent and Trademark Office. USPTO Fee Schedule With attorney fees for drafting the response, expect $3,000 to $6,000 per round.
Appealing to the Patent Trial and Appeal Board is more expensive still. The forwarding fee alone is $2,535 for a large entity, $1,014 small, or $507 micro, and attorney fees for briefing an appeal commonly run $5,000 to $15,000.2United States Patent and Trademark Office. USPTO Fee Schedule
Once the USPTO allows your application, the issue fee is due within three months. Missing that deadline abandons the application.8Office of the Law Revision Counsel. 35 USC 151 – Issue of Patent
Maintenance Fees Over the Patent’s Life
A utility patent requires three maintenance payments to stay in force, due at 3.5, 7.5, and 11.5 years after grant. The amounts rise sharply:9United States Patent and Trademark Office. Maintain Your Patent
- 3.5 years: $2,150 large / $860 small / $430 micro
- 7.5 years: $4,040 large / $1,616 small / $808 micro
- 11.5 years: $8,280 large / $3,312 small / $1,656 micro
Over the full life of the patent, maintenance fees total $14,470 at full price, $5,788 for small entities, and $2,894 for micro entities.2United States Patent and Trademark Office. USPTO Fee Schedule Miss a payment and the patent expires. A six-month grace period follows each deadline but adds a surcharge. Many owners let patents lapse at the 11.5-year mark once the technology has aged out.
Filing Outside the United States
There is no single international patent. Protection outside the U.S. means filing separately in each country or region where you want rights, and that’s where costs go from thousands to tens or hundreds of thousands.
The Patent Cooperation Treaty (PCT) system lets you file one international application that preserves your right to enter the national phase in over 150 countries and delays those expensive national filings by about 30 months from your original filing date.10World Intellectual Property Organization. Twelve Ways to Manage Global Patent Costs Each country you actually enter adds its own government fees, translation costs, and local counsel fees. Protecting an invention in five countries commonly costs $15,000 to $30,000 beyond U.S. costs. Ten or more can push past $50,000.
Translations drive much of the expense. Filings in Japan, South Korea, or Germany require full translations of the specification, running several thousand dollars per country. Picking countries based on where the product will actually be sold or made is the most effective way to hold international costs down.
Cutting the Bill
Claiming the right entity status is the single biggest lever most individual inventors can pull. Micro entity status alone saves more than $14,000 in government fees over the life of a utility patent compared to large-entity rates.4Office of the Law Revision Counsel. 35 USC 41 – Patent Fees; Patent and Trademark Search Systems Small entity status still cuts those fees by 60%.
A provisional application is a cheap way to lock in a filing date for $65 to $325 in government fees and buy a year to decide whether the invention justifies full prosecution costs.7United States Patent and Trademark Office. About Provisional Application for Patent Other moves that make a real difference:
- Run a preliminary prior art search yourself using the USPTO’s free database and Google Patents before paying for a professional search. If you find clear prior art, you’ve saved thousands.
- Spend on drafting quality. A vague or poorly drafted application leads to more Office Actions, more attorney hours, and more RCE fees later.
- Consider a design patent if the visual appearance of your product is what makes it distinctive. At $2,000 to $4,000 with no maintenance fees, it may give you enough protection at a fraction of utility-patent cost.
- File abroad only where you’ll actually manufacture or sell. Every added country brings fees, translations, and local counsel with it.
Free Help Through the USPTO Pro Bono Program
Inventors who can’t afford an attorney may qualify for the USPTO’s Patent Pro Bono Program, which matches applicants with volunteer patent professionals for free legal assistance. Regional programs run independently, so eligibility criteria vary, but the general standard is a gross household income below three times the federal poverty level.11United States Patent and Trademark Office. Patent Pro Bono Program – Free Patent Legal Assistance
You typically need to show a basic understanding of the patent system, either by having a provisional on file or by completing the USPTO’s inventor education course, and you need to be able to describe your invention. The program covers attorney fees but not government fees, though at micro-entity rates those are modest. If you’re an independent inventor with limited funds, apply here before deciding a patent is out of reach.
