Filing Your Provisional with the USPTO
What forms you need, what they cost, and the exact requirements your provisional application has to meet to get a filing date.
Drafting your invention is the creative work. Filing it correctly is the procedural one — and the USPTO is unforgiving about procedural errors. Miss a form, miscalculate a fee, or skip the cover sheet and the Office will issue a Notice to File Missing Parts, delay your application, and charge a late surcharge.
This page walks through everything a complete provisional application needs: the four required pieces, the official forms, the 2025–2026 fee schedule, and the rules around entity status, size fees, and late submissions.
Heads up: Provisional applications are for utility or plant inventions only — you cannot file a provisional for a design invention. Provisionals are also never examined on their merits and cannot claim priority from another application. The 12-month clock starts the day you file.
A Complete Provisional Application
Every provisional needs these four pieces. Miss one and the USPTO will issue a Notice to File Missing Parts.
Written Description (Specification)
A detailed description of your invention — what it is, how it works, and how to make and use it. This is the core of the filing. The future claims of your non-provisional can only reach as far as this description supports, so be thorough.
Drawings (As Needed)
Any drawings necessary to understand the invention. Sketches, photos, screenshots, and CAD all work — formal patent-drawing style is not required at the provisional stage. What's drawn (or not) bounds what you can claim later.
Cover Sheet or ADS
Either the Provisional Application Cover Sheet (PTO/SB/16) or an Application Data Sheet (PTO/AIA/14). Identifies the inventors, the title, the correspondence address, and bibliographic data the USPTO needs to route the file.
Correct Filing Fee
The basic provisional fee under 37 CFR 1.16(d) — reduced 60% for small entities and 80% for micro entities. Plus an application-size fee if your specification + drawings exceed 100 sheets.
USPTO Forms You'll Need
The USPTO publishes specific PDFs for each piece of a filing. Here's what each one does and what data it captures.
Provisional Application Cover Sheet
The primary routing sheet for a provisional filing. Establishes the application as provisional and collects the bibliographic data the USPTO needs.
- Invention title (max 500 characters)
- Inventor names & residential addresses
- Correspondence address or Customer Number
- Attorney/agent info & registration #
- U.S. government interest declaration
- Specification & drawing page counts
- Fee calculations & payment method
- Authorized signature
Fee Transmittal Form
Itemizes every fee being submitted with the application. Tells the USPTO's financial system exactly what to charge and how to credit each fee category.
- Application type (provisional)
- Entity status (Large / Small / Micro)
- Basic filing fee
- Application size fee (if >100 sheets)
- Late filing surcharge (if applicable)
- Non-English specification fee (if any)
- Total fee amount & payment method
- Submitter signature, name, date
Application Data Sheet (ADS)
Provides machine-readable bibliographic data. Can be filed alongside or in place of the SB/16 Cover Sheet. The USPTO's Patent Center auto-loads data directly from this form.
- Inventor names, residency, city/state/country
- Correspondence address or Customer Number
- Application title & type
- Entity status
- Representative (attorney/agent) info
- Assignee information (if assigned)
- Priority claims (n/a for provisionals)
- Authorized signature
Micro Entity Certification
Establishes eligibility for the 80% micro-entity fee discount. SB/15A is for the gross-income basis; SB/15B is for the higher-education basis.
- Application number (or first inventor + title)
- Income verification checkboxes (SB/15A)
- Higher-education status (SB/15B)
- Prior-application count attestation
- Authorized signature, name, date
- Telephone & registration number
Pay 20%–40% of List Price
The USPTO gives steep discounts to independent inventors and small entities. Most pro-se filers qualify for one of these.
Large Entity
Companies with 500+ employees, or that are owned by/assigned to one. No discount applies.
Small Entity
Independent inventors, businesses with fewer than 500 employees, nonprofits, and universities. The most common status.
Micro Entity
Small-entity-qualifying inventors who also meet income limits OR are assigning to a U.S. institution of higher education.
Two ways to qualify as a Micro Entity:
- Gross-Income Basis (Form SB/15A): Your gross income for the prior year is below the USPTO threshold ($251,190 for the 2025–2026 fee window), AND you have not been named on more than four previously-filed nonprovisional U.S. patent applications.
- Higher-Education Basis (Form SB/15B): You are employed by, or contractually obligated to assign your invention to, a recognized U.S. institution of higher education. The income limit doesn't apply.
What You'll Actually Pay
Current USPTO fees for a provisional patent filing, by entity status.
USPTO Fee Schedule
Effective for the 2025–2026 fee window
| Fee | Large | Small (-60%) | Micro (-80%) |
|---|---|---|---|
Provisional filing fee Base fee under 37 CFR 1.16(d) | $325 | $130 | $65 |
Application size fee Per 50 sheets over 100 | $450 | $180 | $90 |
Late filing surcharge Missing cover sheet or fee on filing date | $60 | $24 | $12 |
Non-English specification Processing fee for non-English filings | $140 | $56 | $28 |
Fees shown reflect the USPTO fee schedule that took effect Jan 19, 2025. Always verify the current rate at uspto.gov before filing.
Common Filing Pitfalls
The traps that turn a simple filing into a delayed one with extra fees attached.
Missing the cover sheet or filing fee
If you skip the SB/16 (or ADS) or don't pay the filing fee at submission, the USPTO issues a Notice to File Missing Parts and tacks on a late surcharge before your application is considered complete.
Forgetting to claim micro-entity status
You must file the SB/15A or SB/15B certification at or before fee payment. Pay the small-entity rate by accident and you cannot retroactively claim micro status for that filing.
Going over 100 pages without budgeting
Specification and drawings combined are counted toward the 100-page threshold. Every additional 50 sheets (or fraction) triggers an application size fee that compounds quickly with long disclosures.
Forgetting the 12-month deadline
Provisionals expire exactly 12 months after filing. If you don't file a non-provisional that claims benefit of your provisional before that date, your priority date is lost — permanently. No extensions, no exceptions.
Inadequate disclosure (the silent killer)
Your future non-provisional claims can only reach as far as your provisional description supports. A thin or vague description means narrower claims later — or worse, claims a competitor can design around.
Patent Center upload mistakes
Individual documents max out at 25 MB. Embedded multimedia, hyperlinks, security encryption, or unembedded fonts will trigger an ingestion rejection. Downsample images to 300 DPI or less.
USPTO forms only work properly in Adobe Acrobat / Reader
The USPTO publishes its official forms in a rigid Adobe-proprietary format (XFA — XML Forms Architecture). To view, fill, or sign them, you must open them with Adobe Acrobat or Adobe Reader (free).
Almost every other PDF viewer — Chrome's built-in viewer, Edge, Firefox, Safari, Apple Preview, and most mobile readers — cannot render these forms. Instead you'll see a placeholder message:
That's not a bug in the form — it's a limitation of the USPTO's chosen format. If you see this message, save the file and re-open it in Adobe Reader. Once you have the right viewer, fields fill normally, signatures stick, and the USPTO's Patent Center can auto-load your data on intake.
Drawings: Good Enough Beats Perfect
Formal patent drawings aren't required at the provisional stage. Sketches, photographs, screenshots, and CAD files all qualify — what matters is that they clearly show the invention.
That said, the drawings you submit set the boundary of what your description supports. Anything not visually or textually disclosed in your provisional cannot be added later when you convert to a non-provisional. Be generous: include views, alternates, and annotations now.
