Provisional vs. Non-Provisional Patent Applications: What You Really Get for $325

A Placeholder, Not a Patent

A provisional application gives you a filing date and 12 months to decide what to do next. It is never examined and can never become a patent by itself. A non-provisional application is the one the USPTO actually examines.

That makes the provisional a useful tool with one serious limit: it only secures a date for what it describes. A thin provisional filed in a hurry can leave you with a receipt and no real priority.

What Each Filing Costs

These are USPTO government fees from the schedule that took effect on January 19, 2025, as listed on November 6, 2026 (USPTO Fee Schedule). They exclude attorney fees, which are usually the larger cost.

The totals are our arithmetic, and they assume no more than 3 independent claims, 20 total claims, and a specification filed in DOCX. Filing in another format adds a surcharge of $430, $172 or $86, though provisionals are exempt (USPTO Consolidated Rules).

Do You Qualify for a Discount?

Small entities receive 60% off most fees, and micro entities receive 80% off (FY2025 Fee Rule, 89 FR 91898). Small entity status generally covers individuals, nonprofits and businesses with no more than 500 people including affiliates, provided you have not transferred rights to a larger party (37 CFR 1.27).

Micro entity status has more tests. You must qualify as a small entity, not be named on more than four previously filed applications, and stay under an income limit (35 USC 123). That limit rose to $262,380 on September 15, 2026 (USPTO Micro Entity Status), and it applies to each applicant and inventor individually (37 CFR 1.29).

Getting this wrong can be expensive. A false assertion made other than in good faith carries a fine of at least three times the amount underpaid (35 USC 41).

Side by Side

A provisional needs a written description and any necessary drawing, but no claims and no oath (35 USC 111; MPEP 201.04). It is not published (35 USC 122), but it can become publicly available once a later patent or publication claims its benefit (37 CFR 1.14). Assume it will be read one day.

Because patent term runs from the non-provisional filing date and priority is not counted, a patent can last up to about 21 years from the provisional date (35 USC 154).

The Two Deadlines People Confuse

The 12-month filing deadline. Your non-provisional must be filed within 12 months of the provisional, and that period cannot be extended (USPTO Provisional Application Page). There is a narrow rescue: within 14 months, you can petition to restore the benefit if the delay was unintentional, for a fee of $2,260, $904 or $452 (37 CFR 1.78). Treat that as a US remedy only, and do not assume it protects rights in other countries.

The benefit claim deadline. Filing on time is not enough. The non-provisional must also reference the provisional, by the later of four months from its own filing date or sixteen months from the provisional's filing date, or the benefit is waived (37 CFR 1.78). The reference goes in the application data sheet (MPEP 211).

If you miss the second deadline, you need a petition. Since August 13, 2026, a petition filed more than one year after the due date costs $3,000 undiscounted rather than $2,260 and requires a fuller explanation. That threshold used to be two years (Federal Register 2026-12717).

The later application must also name at least one inventor from the provisional (MPEP 211).

Why a Thin Provisional Can Fail

A later claim gets the provisional's date only if the provisional supports it under the written description and enablement requirements of § 112(a) (MPEP 211).

New Railhead v. Vermeer shows the risk. A provisional for a drill bit did not describe the angle that the later claims required, and passing references to a "high angle of attack" were not enough. The patent lost the provisional's date, so the company's own earlier commercial sales became prior art and the claims were invalid (New Railhead v. Vermeer).

The point keeps coming up. In August 2026, the Federal Circuit rejected the view that a provisional's support is a mere formality when a patent relies on that provisional to count as prior art, according to a WilmerHale summary of Dental Monitoring v. Align, No. 2025-1752.

A good provisional reads like a real application. Describe every feature you may want to claim, how to make and use it, the alternatives you considered, and your drawings. Our guide to common filing mistakes covers more of these traps.

Which Should You File?

A provisional usually fits when:

• You need a date before a demo, pitch or publication
• The design is still changing and you need time to validate the market
• You want up to a year to defer the larger non-provisional costs

A non-provisional usually fits when:

• The invention is stable and you want examination to start
• Time to grant matters to your fundraising or licensing plans
• You would have to write a full specification anyway to protect yourself

Filing a non-provisional first has a timing advantage: first-action pendency at the end of FY2026 was 20.5 months (USPTO FY2026 Pendency Review), and that clock only starts when you file one.

If you need speed, Track One aims for final disposition within about twelve months (USPTO Track One Page). It adds $4,515, $1,806 or $903 plus a processing fee of $150, $60 or $30, allows at most four independent and thirty total claims, and is not available for provisionals (37 CFR 1.102). By our arithmetic, that is $6,665, $2,596 or $1,333 in government fees through examination.

The Bottom Line

The $325 buys a date, and only for what you wrote down. Spend your effort on the disclosure, put the 12-month deadline in your calendar on the day you file, and confirm that the benefit claim is in the application data sheet.
