How to file a provisional patent application
The platform produces a USPTO-ready bundle. You perform the final submission yourself in Patent Center — about 5 minutes once you know the flow. This guide walks through every step, with citations to USPTO's official guidance.
Not legal advice. patentideagenerator is a software tool, not a law firm. This guide summarizes USPTO public guidance for pro-se inventors filing under 37 CFR 1.53(c). For strategic decisions (claim scope, when to file, foreign filing) consult a registered patent attorney or agent.
What you're filing
A provisional patent application establishes a filing date for an invention without starting examination. It buys you 12 months to convert to a non-provisional application or abandon. Provisional applications are not published, are not examined, and never issue as patents on their own — they exist only to lock in priority. (USPTO: Provisional applications)
Required documents (in your bundle)
USPTO requires four things to grant a filing date for a provisional (35 U.S.C. §111(b), 37 CFR 1.51(c)). The platform produces all of them in a single zip:
- 01Written description(the “spec”) — describes the invention with enough detail that a person skilled in the art could practice it (35 U.S.C. §112(a)). PDF or DOCX.
- 02Drawings — strongly recommended; required when necessary to understand the invention (35 U.S.C. §113). Cannot be added after filing.
- 03Cover sheet— Application Data Sheet (PTO/AIA/14) or Provisional Cover Sheet (PTO/SB/16). Must identify the application as provisional and list every inventor's legal name and residence. Pre-filled in your bundle.
- 04Filing fee per 37 CFR 1.16(d). Paid at submit time (next section).
Claims are not required in a provisional application, though the platform includes them so the spec maps cleanly to the eventual non-provisional. The presence of claims does not change fees or filing date.
Filing fees (37 CFR 1.16(d))
| Entity size | Provisional fee | Late surcharge |
|---|---|---|
| Micro entity | $65 | $13 |
| Small entity | $130 | $26 |
| Standard / large entity | $325 | $65 |
Source: USPTO fee schedule. Fees adjust roughly annually; check current rates before filing. Most independent inventors qualify as micro entity (gross income under ~$240K, no more than 4 prior applications, not assigned to a non-micro). Add the platform's service fee on top of the USPTO fee.
Filing in Patent Center — step by step
USPTO replaced the legacy EFS-Web system with Patent Center. As of September 2025, all filers must verify identity via ID.me (online; no notary needed) before submitting.
- 1.Create / sign in to USPTO.gov. Go to patentcenter.uspto.gov. First-time users: complete ID.me identity verification (driver license + selfie). Existing MyUSPTO users sign in directly. MFA required.
- 2.Start a new submission. From the dashboard, click New Submission → Provisional Application for Patent.
- 3.Upload the bundle. Drag-and-drop the spec, drawings, and cover sheet (or DOCX equivalent) from the zip we generated. Patent Center accepts PDF and DOCX.
- 4.Confirm Application Data Sheet (ADS). The cover sheet pre-fills inventor names, title, and correspondence address from your persona. Verify accuracy — every inventor listed must have made a real contribution to the invention.
- 5.Select entity size + pay. Choose Micro / Small / Standard. Pay by credit card or USPTO deposit account. Real-time payment confirmation.
- 6.Capture the receipt. Patent Center generates two receipts (submission + payment) under the Documents & Transactions tab. Note the application number (formatted US 63/XXX,XXX). Paste both back into /drafts/[id] on patentideagenerator. Receipts may take up to 1 hour to appear — if they don't, contact the Patent EBC.
The 12-month clock starts at filing
You have exactly 12 months from the provisional filing date to either (a) file a non-provisional application claiming priority, or (b) abandon. The deadline cannot be extended. A 14-month grace period exists via petition with an unintentional-delay statement and additional fee (37 CFR 1.78), but relying on it is risky and expensive.
Record your application number on your /filings page so the filing date is on record — and put the 12-month date in your own calendar; automated deadline reminders are on our roadmap but not built yet. The non-provisional must include a specific reference to the provisional in its ADS to claim priority.
Common mistakes to avoid
- Misnaming inventors. Every inventor on the cover sheet must have contributed to the invention as filed. Adding non-inventors (or omitting real ones) can void the priority claim.
- Forgetting drawings.Drawings cannot be added after filing. If they're necessary to understand the invention and missing, the filing date may be invalid.
- Public disclosure before filing. US offers a 12-month grace period after public disclosure (35 U.S.C. §102(b)(1)). Most other countries do not — pre-filing disclosure often kills foreign rights.
- No information disclosure statements (IDS). IDS filings are not accepted in provisional applications.
- No design patents via provisional. Provisional applications are only for utility inventions.
- Late cover sheet surcharge.If you somehow file without the cover sheet, you can add it later but pay the surcharge (table above). The platform's bundle includes the cover sheet by default.
