A seed-stage patent budget built line by line at 2026 USPTO fees: about $25,000 per family through grant, and how the number moves with your milestones.
A seed-stage company should plan on about $25,000 for one patent family at small entity rates, from the provisional through grant and the first maintenance fee, with about $18,400 of it landing in the first 24 months. The rest is gated on events you can name: the next raise, a launch, a partnership. Set the budget from those events, not from a percentage of R&D.
The rule of thumb most founders hear comes from Russ Krajec at BlueIron, who wrote in 2022 that established companies spend about 1 percent of R&D on patents, roughly $10,000 per $1 million, and that a startup building a portfolio from zero may need to run closer to 5 percent. As a description of mature companies, that matches what we see. As a budgeting tool for a seed company, it fails in both directions.
Take a company spending $1.5 million a year on engineering. One percent is $15,000, which does not cover converting a single provisional. Five percent is $75,000, which would fund three families the company may not need yet. The ratio cannot tell you which of those is right, because the answer depends on what the company has to prove in the next year and a half, not on what it spends on engineers.
Our own company budget guide uses the 1 percent figure the way we use it with clients: as a reasonableness check after the fact. The budget itself comes from counting. How many inventions worth filing will the team produce this year, what does each one cost at your entity size, and which business events make that spend worth it.
A newer variant ties the budget to the round instead. Beyond Elevation’s stage guide, updated in August 2026, suggests 2 to 4 percent of your latest raise in year one. Its stage ranges ($15,000 to $40,000 a year at seed, $50,000 to $120,000 at Series A) are close to ours, and its sequence (trade secrets first, then provisionals) is sound. The percentage is the part we would drop: on a $3 million seed round, 2 to 4 percent is $60,000 to $120,000, well above its own seed range, and a $6 million round does not contain twice as many inventions worth protecting as a $3 million one.
Government fees are the easy part. The USPTO fee schedule is public, its patent fees took effect on January 19, 2025, and the PCT amounts on it were last reset on August 1, 2026. At small entity rates, which means fewer than 500 employees and no assignment or license to a large company, a startup will actually pay:
Micro entity status halves most of those again. In 2026 it requires gross income under $251,190 for the company and for each inventor, and no inventor named on more than four earlier U.S. applications (provisionals do not count). Whether a funded startup qualifies is a question for your patent attorney. Applied to the example that follows, micro entity rates would cut the USPTO fees by about $1,700 (the international filing fee carries no discount), roughly one office action response.
Attorney fees are the part that dominates, and the part you control. Our published ranges: a provisional drafted like a patent runs $2,000 to $6,000; a U.S. utility application $8,000 to $15,000 or more; each office action response $1,500 to $3,000 or more, with two or three rounds normal in our experience. Flat-fee providers quote lower. Tradespace’s August 2026 guide puts flat-fee utility drafting at $3,000 to $8,000 and responses at $500 to $2,000, against $6,000 to $15,000 and $2,000 to $6,000 at hourly boutiques.
Our read is that the specification is the wrong place to save. A thin draft is cheap to file and expensive at month eleven, when the claims you now want have nothing in the text to support them. Save on the routine work instead. Extension fees are pure waste. Examiner interviews are usually money well spent. And a disclosure complete enough that the attorney’s first draft is close will do more for the budget than any fee negotiation.
Nine people, small entity, one invention the business cannot afford to lose, and a Series A planned within a year and a half. Attorney fees at working estimates inside the ranges above: $5,000 for the provisional, $10,000 for the utility application, and $2,500 per office action response.
Month 0: file a provisional drafted like a patent. $130 to the USPTO and $5,000 in drafting. $5,130.
Month 6: re-project the full cost of converting and make a preliminary go or no-go call. No spend. This is the meeting we see most companies skip, and it is the one that keeps conversion from becoming an emergency purchase against a fundraising deadline. We went through the whole post-filing calendar on Invent Anything episode 72: Your Provisional Patent Is Filed: Now What?
Month 12: convert to a U.S. utility application ($800 in fees plus $10,000 in drafting) and file the PCT to keep foreign options open ($2,490 in government fees, plus attorney time). $13,290, for a running total of $18,420.
Months 24 to 40: two office action responses at $2,500 each, then the $516 issue fee. $5,516, running total $23,936.
Three and a half years after grant: the first maintenance fee, $860. Running total $24,796.
Two things stand out. Government fees are about $4,800 of the $24,800, under 20 percent; attorney fees are the budget. And the spend is front-loaded on decisions but back-loaded on cash. About $18,400 lands in the first 24 months, and the rest arrives on the examiner’s schedule. The USPTO said in April 2026 that first office actions within a fiscal year were exceeding new filings for the first time in nearly a decade, with a goal of virtually eliminating applications that would otherwise wait more than 36 months. Good news, and it still means most of your office action invoices belong to the budget cycle after next.
One family through grant lands at the bottom of our seed-stage range of $20,000 to $60,000 across the stage. Two families fill it. So does one family plus what is deliberately missing from the total above: at month 30 the PCT comes due country by country, at $3,000 to $8,000 or more per country at entry, before translations, local counsel, and annuities. Our budget guide puts broad international coverage at 10 to 15 times a U.S.-only budget over a patent’s life. That decision gets its own post later this year. For now, put the date in the model with a placeholder next to it.
Before you take a number to the board, run your own version of this example. The Patent Cost Calculator lets you pick the jurisdictions you are actually considering and see filing, prosecution, and maintenance costs side by side; it uses large entity assumptions, so a small entity’s government fees will come in lower than it shows.
Our approach is to budget patents against business events, because an event is when a patent changes an outcome. Four versions of the same nine-person company:
Patentext’s Alexander Flake recommends filing the provisional four to six months before a seed raise and converting after the money lands, so “patent pending” is on the deck without the conversion cost coming out of pre-seed runway. We agree with the timing, and we would bolt the month-6 re-projection onto it. With that sequence, month 6 falls right around the close, which is the first moment you actually know how much runway the conversion is competing with.
Russ Wilcox, writing for Built In in 2020, argued that filing one application for under $10,000 is a reasonable use of seed money, that spending more to protect a moderate edge usually is not, and that the money should go into building a hit product. The spirit is right. The number is a filing number, though, not a patent number. The example above spends $18,400 by month 12 and $24,800 by the first maintenance fee, and a board that heard “under $10,000” will read the office action invoices as a plan that slipped. Present the whole path, then gate the second half.
Boards approve patent spending when it arrives as a plan with dates rather than a legal expense with a range. The format we have found works is three buckets:
Then report the ratio to R&D afterward, as a sanity check. If it lands near 1 percent for a company your size, fine. If it lands at 5 percent, you should be able to point at the milestones that pushed it there.
A patent budget is a schedule of decisions with prices attached. If the board can see the dates, it can see the plan.
Keep the government fee lines and the attorney fee lines separate in the model. The first set is fixed and public. The second is where your choices show up: which attorney, how complete the disclosure was, whether anyone paid for an extension. When a director asks why the number moved, you want a one-sentence answer.
If you have a provisional in flight, run the month-6 re-projection now, even if month 6 has passed. Put the conversion cost, the PCT decision, and the month-30 date in one model with the small entity fees above, and take it to the next board meeting in the three-bucket format.
If you have not filed, pick the one invention you cannot afford to lose and get a provisional drafted like a patent before the deck goes out. Ask a patent attorney about entity status and the filing itself. Talk with our team if you want help putting a realistic number on the plan.
