Provisional vs. Utility Patent Application
Provisional vs. utility patent applications: cost, examination, the 12-month deadline, and what each does (and doesn't) establish for inventors.
Side-by-side comparison
| Dimension | Provisional Application | Utility (Non-Provisional) Application |
|---|---|---|
| Statutory basis | Filed under 35 U.S.C. 111(b). A specification (with or without formal claims) filed to establish a filing date -- it has no separate patent grant of its own. | Filed under 35 U.S.C. 111(a), together with 112 (written description/enablement/claims) and 131-135 (examination). This is the application that, if allowed, actually issues as a granted patent. |
| Examined by USPTO? | No. A provisional is never examined, never published, and never issues as a patent -- it exists only to hold a filing date. | Yes. Assigned to an examiner, who searches prior art and issues office actions the applicant must respond to before (if ever) allowance. |
| Formal claims required? | No. USPTO guidance does not require claims, an oath/declaration, or an information disclosure statement in a provisional filing -- though 112(a)'s written-description and enablement requirements still apply, since anything not adequately described can't later claim its priority date. | Yes. One or more claims defining the legal scope of the invention are required under 35 U.S.C. 112(b), along with an oath/declaration and, where relevant prior art is known, an IDS. |
| What it establishes | An early priority date ("patent pending" status) for whatever is adequately described in the specification -- and nothing more. It creates no enforceable right. | The actual examined application; if it issues, it becomes an enforceable utility patent giving the owner the right to exclude others from making, using, selling, or importing the claimed invention. |
| Pendency / if you do nothing | Automatically regarded as abandoned exactly 12 months after filing under 35 U.S.C. 111(b)(5), with no revival available after that -- USPTO guidance states the 12-month period "cannot be extended." | Remains pending through examination -- which can take one to several years -- until it is allowed, issued, abandoned, or prosecution otherwise ends. |
| USPTO filing fee (2026 schedule) | $325 (large entity) / $130 (small entity) / $65 (micro entity) -- filing fee only, since it is never examined. | Filing + search + examination together run roughly $2,000 (large entity) / $800 (small entity) / $400 (micro entity) before attorney costs. |
| Converting to the other type | Must be followed, within 12 months, by a non-provisional application claiming benefit of the provisional's filing date under 35 U.S.C. 119(e) -- otherwise it lapses and the priority date is lost. | Nothing to convert to -- already the examined track. (Converting a provisional itself into a non-provisional under 37 CFR 1.53(c)(3) is rarely used, since USPTO guidance notes it shortens the resulting term.) |
| Effect on the 20-year patent term | None, if handled via 119(e) priority -- 35 U.S.C. 154(a)(2) measures the 20-year term from the earliest non-provisional filing date, explicitly excluding provisional priority claims. | This is the filing date the 20-year term is measured from. |
| Typical use case | Locking in a priority date quickly and cheaply -- before a publication, conference talk, investor pitch, or public disclosure -- while claims are refined and funding or licensing interest is assessed. | The application actually intended to mature into an enforceable patent, once the invention, claims, and disclosure are ready for full examination. |
Common questions
FAQ
Does filing a provisional patent application mean I have patent protection?+
No. A provisional application creates no enforceable right -- there is nothing to infringe, because nothing has been examined or granted. It only establishes a priority date and "patent pending" status for a non-provisional application that must follow within 12 months.
What happens if I miss the 12-month deadline to convert a provisional?+
The provisional is automatically regarded as abandoned under 35 U.S.C. 111(b)(5) and cannot be revived. Any priority claim to it is lost -- a later-filed application only gets its own, later filing date, which can create a novelty or on-sale-bar problem if the invention has since been disclosed or sold.
Can I use a provisional application to support a foreign or PCT filing?+
Yes. Under the Paris Convention, an applicant has 12 months from a provisional's U.S. filing date to file a corresponding PCT application or foreign national applications claiming the same priority date.
Is a provisional patent application ever published or examined by the USPTO?+
No. Provisional applications are never published and never examined -- they exist solely to establish a filing date for a later non-provisional application to claim benefit of.
