"How much does a patent cost?" is the first question every inventor asks, and the answer most websites give — "it depends" — is useless. The AIPLA Report of the Economic Survey gives a real one. Every two years it asks hundreds of working IP attorneys what they actually charge for each step of getting a patent, and publishes the medians. This is that bill, itemized.
A warning up front, because it's the most common way these numbers get misread: the survey charges are attorney fees only. They exclude USPTO government fees, exclude formal drawings, and assume "no unusual complications." The real all-in cost is higher, and we'll add the missing pieces at the end.
Where the numbers come from
The figures below are median charges from the AIPLA Report of the Economic Survey, prepared for AIPLA's Law Practice Management Committee by an independent survey firm. Respondents report the typical charge for each service — but only for work they personally handled, as a service provider or a purchaser, on a case with no unusual complications, counting legal services only (no government fees, no draftsman fees).
The most recent edition is the 2025 Report (released February 2026), whose detailed tables are available to AIPLA members and as a paid digital copy. The most recent figures documented publicly in detail come from the 2023 Report (2022 data), which is what the tables below use. One thing the 2025 edition specifically expands on is the flat-fee-versus-hourly split for each task — a useful lens we'll come back to.
The core bill: drafting and filing a US patent
Here's the median attorney charge to prepare and file a US patent application, by what kind of application it is and how complex the technology:
| Application type | Median charge (2022) | Typical range (1st-3rd quartile) |
|---|---|---|
| Provisional application | $5,000 | $3,000 - $7,300 |
| Non-provisional, minimal complexity | $8,000 | $6,500 - $9,000 |
| Non-provisional, complex — mechanical | $10,000 | $8,000 - $11,500 |
| Non-provisional, complex — electrical / computer | $11,000 | $8,500 - $14,000 |
| Non-provisional, complex — biotech / chemical | $12,000 | $9,788 - $15,000 |

The technology drives the price. A biotech or chemical application — long specifications, dense claim sets, working examples — runs a median of $12,000 to draft, half again as much as a "minimal complexity" mechanical gadget at $8,000. A provisional is cheaper at $5,000, but remember what a provisional is: a one-year placeholder that buys you a priority date and time to file the real thing. Its cost is added to, not subtracted from, the non-provisional you'll file within twelve months.
The part nobody budgets for: prosecution
Filing the application is the start of the meter, not the end. After filing, a USPTO examiner almost always rejects the claims at least once, and you respond. That back-and-forth — "prosecution" — is its own line of charges:
| Service | Median charge (2022) |
|---|---|
| Office-action response, minimal complexity | $2,000 |
| Office-action response, complex (mechanical) | $3,000 |
| Office-action response, complex (electrical / computer) | $3,500 |
| Office-action response, complex (biotech / chemical) | $3,500 |
| Examiner interview (prepare & conduct) | $1,000 |
| Issuing an allowed application (all post-allowance work) | $750 |
| Appeal to the PTAB, no oral argument | $5,000 |
| Appeal to the PTAB, with oral argument | $8,000 |
Source: AIPLA Report of the Economic Survey 2023, median charge, 2022 data.
Most applications draw two or three office actions before allowance, so budget $4,000-$10,000 of prosecution on top of the drafting fee — more if the examiner digs in and you end up at an interview or an appeal. This is why a patent that "cost $8,000 to file" routinely costs $15,000+ by the time it issues.
Knowing before you build: opinions and searches
Separate from getting your own patent, the survey prices the diligence work — what it costs to find out whether an idea is patentable, or whether you're clear to launch a product:
| Opinion / search | Median charge (2022) |
|---|---|
| Novelty (patentability) search, analysis & opinion | $2,500 |
| Validity / invalidity opinion, per patent | $10,500 |
| Infringement / non-infringement opinion, per patent | $10,000 |
| Combined validity + infringement opinion, per patent | $15,000 |
| Ex parte reexamination | $10,000 |
Source: AIPLA Report of the Economic Survey 2023, median charge, 2022 data.
Note how much more expensive an invalidity opinion ($10,500) is than a patentability search ($2,500). Tearing a granted patent apart is far more work than checking whether your own idea is new — a preview of the cost asymmetry that runs through the whole system.
Flat fee or by the hour?
The 2025 Report leans into a question the survey has tracked for a while: do practitioners charge a flat fee or bill hourly for each task? The 2022 data shows a clear pattern that's worth knowing before you sign an engagement letter:
- Drafting and prosecution skew hourly. Preparing a non-provisional, responding to office actions, and arguing complex cases are billed hourly more often than not (roughly 51-61% hourly across the drafting and amendment tasks). The work is open-ended, so firms hedge.
- Administrative and post-allowance work skews flat. Paying a maintenance fee (about 68% flat), issuing an allowed application (about 59% flat), and filing a short information-disclosure statement (about 60% flat) are predictable enough to quote a fixed price.
Where firms reported both, the hourly median usually lands a bit above the flat-fee median for the same task — e.g., a complex biotech/chemical application ran a median of about $10,500 flat versus $13,000 hourly. A flat fee buys you cost certainty; hourly can come out cheaper on a clean case and much worse on a messy one. The survey can tell you the going rate; only your facts tell you which structure to pick.
What the survey leaves out
The medians above are attorney fees. To get to a real all-in cost for a single US utility patent, add:
- USPTO government fees — filing, search, examination, and (at the end) the issue fee. These run from a few hundred dollars for a micro-entity up to a couple thousand for a large entity, and they were adjusted in 2025, so check the live USPTO fee schedule before budgeting.
- Formal drawings — a draftsman's charge, often a few hundred dollars, which the survey explicitly excludes from the legal-services figures.
- Maintenance fees — to keep a patent alive its full 20-year term, you pay the USPTO at 3.5, 7.5, and 11.5 years (escalating to several thousand dollars each), plus a small attorney charge to docket and pay them (a median of about $333 per payment).
Put it together and a single US utility patent, drafted and prosecuted to issuance, realistically runs $10,000-$20,000 in attorney fees plus government fees — consistent with the $10,000-$15,000 ballpark in How to obtain a patent. A complex biotech case, or one that needs an appeal, runs higher.
The trend: prosecution costs barely moved
Here's something the long survey series makes obvious — and that makes the patent-troll problem sharper. Median drafting charges have grown only modestly over fourteen years:
| Application type | 2008 | 2022 |
|---|---|---|
| Provisional | $3,500 | $5,000 |
| Non-provisional, minimal complexity | $7,000 | $8,000 |
| Non-provisional, mechanical | $9,000 | $10,000 |
| Non-provisional, electrical / computer | $10,000 | $11,000 |
| Non-provisional, biotech / chemical | $12,000 | $12,000 |
Source: AIPLA Report of the Economic Survey 2023, median charge for preparation and filing.
Biotech drafting fees are flat across fourteen years; the rest crept up 10-40%. Getting a patent has stayed cheap and predictable. Enforcing one, as the litigation-cost numbers show, costs millions — and that gap is the whole story.
Why this belongs on a patent-troll site
Walk the asymmetry end to end:
- A real inventor pays roughly $10,000-$20,000 to obtain a single US patent the honest way.
- A troll often doesn't even pay that — it buys patents in bulk at bankruptcy fire-sales for a few thousand dollars each, then asserts them. (See how patent trolls operate.)
- And it costs a defendant a median of $1.5M-$3.2M to challenge a granted patent in court, or $350,000+ to challenge it at the PTAB.
Cheap to obtain, cheaper to acquire secondhand, devastating to challenge. The same cost structure that makes patents accessible to inventors is what makes them weapons in the wrong hands. Knowing the real numbers at each stage is the first step to seeing the game clearly.
Bottom line
A US utility patent costs a median of $8,000-$12,000 in attorney fees to draft and file, plus $4,000-$10,000 of prosecution, plus USPTO fees, drawings, and decades of maintenance fees — call it $10,000-$20,000 all-in for a straightforward case. Those costs have stayed remarkably flat for over a decade. The expensive part of the patent system was never getting the patent; it's everything that happens when someone tries to enforce a bad one.
