A provisional patent application is a powerful tool for inventors looking to secure an early filing date without the complexities and costs associated with a full patent application.
By granting ‘patent pending’ status, it opens a window of 12 months for inventors to refine their inventions and explore market potential.
In this article, we’ll delve into the intricacies of what a provisional patent application entails, its key features, the strategic benefits it offers, the step-by-step filing process, and pitfalls to maximize your invention’s potential.
A provisional patent application serves as a preliminary measure for inventors, acting as an initial reservation for their invention. By filing this type of application, you establish an early and crucial filing date that plays a vital role in claiming precedence over any similar prior art. Securing this date not only has implications on the length of your patent rights, but also allows you to mark your invention with ‘patent pending’, thus discouraging imitators.
The advantage of opting for a provisional patent lies in its less complex nature. Provisional applications bypass the extensive examination process typical of non-provisional patents carried out by the United States Patent and Trademark Office (USPTO), offering inventors leeway to perfect their innovation without immediate concern for full statutory requirements.
Nevertheless, it’s important to note that such provisional filings are merely stopgap measures. They alone cannot evolve into enforceable patents unless they’re followed by submitting a complete non-provisional application within one year from when the provisional application is filed. By doing so, you can claim the benefit of the provisional, establishing an earlier filing date for the subsequent non-provisional application, which is a strategic advantage under the first to file system. While these applications can provide strategic value temporarily, engaging with a skilled patent attorney could be instrumental in navigating long-term protection strategies tailored to the particularities of your creation.
A noteworthy aspect of filing a provisional patent application is its consistent 12-month duration before expiration. This timeframe does not require the submission of formal patent claims or an affidavit, which streamlines the process significantly. Inventors benefit by having the opportunity to present their invention in full detail absent the intricacies associated with crafting formal patent claims.
An additional advantage conferred during this period is the entitlement to label your invention as ‘patent pending,’ which may discourage potential infringement and provide interim protection while you refine your creation. By ensuring that your written description within this application is thorough and all-encompassing, you effectively safeguard your initial filing date, laying down a solid groundwork for future non-provisional applications.
Provisionals are available for utility and plant inventions only, not designs. The USPTO never examines or publishes a provisional; it becomes public only if a later published application or patent claims it.
| Feature | Provisional | Non-provisional |
|---|---|---|
| Examined by the USPTO | No | Yes |
| Claims and inventor declaration | Not required | Required |
| Can become a patent | No | Yes, if allowed |
| How long it lasts | 12 months, no extension | Until it issues or is abandoned |
| Published | Never | Usually 18 months after the earliest filing date claimed |
| Counts toward the 20-year term | No | Yes, the term runs from its filing date |
| USPTO fees, large entity | $325 | $2,000 for filing, search, and examination |
A provisional patent application must include a written description that explains how to make and use the invention, any drawings needed to understand it, a cover sheet (Form PTO/SB/16) or application data sheet that names every inventor, and the filing fee. Formal claims, an inventor oath or declaration, and a prior art statement are not required.
The USPTO suggests organizing it as a title, background, summary, drawings, and detailed description. Name everyone who contributed to the conception of at least one claim.

Submitting a provisional application for a patent is beneficial in several ways and can be particularly appealing to inventors. It stands as an economical choice when compared to the complete patent applications, enabling inventors to establish an early effective filing date. This allows them to gauge their invention’s market potential without having to invest heavily upfront. The initial filing fee is quite reasonable, with additional discounts available for entities classified as small or micro, thus underscoring the cost-effectiveness of opting for a provisional.
Choosing the path of filing a provisional allows you more leeway regarding formal requirements which translates into reduced expenses associated with preparation and submission processes. Inventors are granted latitude during this period so they may refine their creations and accrue critical insights from industry participants before embarking on the journey toward submitting a full-scale non-provisional patent application.
A provisional lets a startup lock in its filing date for a USPTO fee of $65 to $325, then talk openly with investors, partners, and early customers. You can spend the 12 months testing the market and raising money before paying for a full application, and decide what to claim once you know which features matter.
A notable benefit of this approach is that it immediately bestows on your idea ‘patent pending’ status right after submission. Such status puts others on notice that you are seeking protection and increases its perceived value in discussions with would-be investors or partners, something especially crucial for startups aiming at safeguarding their concepts while exploring financial backing and marketplace reception.
If the product changes during the year, file another provisional for the new features rather than waiting. One non-provisional filed within 12 months of the earliest provisional can claim several of them, though each feature keeps only the date of the provisional that first described it. Software and mobile apps follow the same path, as long as the description explains how the technology works, not just the idea.
You get “patent pending” status by filing a patent application with the USPTO. A provisional application is the fastest and least expensive way to do it: once the USPTO receives a provisional with a written description of the invention, the application has a filing date, and you may mark your invention “patent pending” while it is pending. Marking a product “patent pending” when no application has been filed, in order to deceive the public, is prohibited by federal law (35 U.S.C. § 292).
“Patent pending” is a notice, not a right you can enforce. You cannot sue anyone for infringement until a patent is granted, which is why the provisional must be followed by a non-provisional application.
With only a provisional on file, patent pending status lasts 12 months; a non-provisional filed in time keeps it until a patent issues or the application is abandoned.
To file a provisional patent application, write a detailed description of your invention with any drawings needed to understand it, prepare a cover sheet (Form PTO/SB/16) or application data sheet naming every inventor, and submit everything through the USPTO’s Patent Center with the filing fee: $325, $130, or $65 depending on your entity size.
USPTO fees under the fee schedule effective January 19, 2025:
| Fee | Large entity | Small entity | Micro entity |
|---|---|---|---|
| Provisional filing fee | $325 | $130 | $65 |
| Surcharge for a late fee or cover sheet | $65 | $26 | $13 |
| Size fee, each 50 sheets over 100 | $450 | $180 | $90 |
Small entity rates cover individuals, nonprofits, and businesses with up to 500 employees that have not licensed or assigned rights to a larger company. Micro entity rates add income and prior-filing limits and a signed certification.
Yes, the government fee is low and you can file yourself. The risk is a bare-bones filing: your non-provisional gets the early date only for what the provisional describes.
A provisional lasts 12 months from its filing date and cannot be extended, though a deadline on a weekend or federal holiday moves to the next business day. If no non-provisional claims it in time, it expires and its filing date is lost.
| Time from filing | What happens |
|---|---|
| Month 12 | Deadline for your non-provisional, PCT, and foreign applications that claim the provisional. |
| Month 14 | Last day to file the non-provisional with a petition for unintentional delay. |
| Month 30 | PCT national phase deadline in most countries. |
No, but it starts the 12-month Paris Convention priority year, so a PCT application or foreign filings made within 12 months can claim its date. Many countries give no grace period for your own disclosures, so file before you pitch or sell. For a U.S.-made invention, check that your filing receipt grants a foreign filing license, or wait six months.
Within 12 months, file a non-provisional application that claims the provisional by application number in the application data sheet, with claims, an abstract, an inventor declaration, and the filing, search, and examination fees. Only what the provisional actually describes keeps the earlier date. Converting the provisional itself by petition is possible, but the patent term then runs from the provisional’s date.
You are not required to hire one. The USPTO accepts provisional applications from inventors filing on their own, and its Pro Se Assistance Center answers procedural questions, though it cannot give legal advice. Because a provisional is never examined, no one checks whether it is detailed enough until you rely on it later, and that is where a patent attorney adds the most value.

A provisional patent application serves as a temporary measure for inventors to secure an early filing date and obtain ‘patent pending’ status, allowing them time to refine their invention.
A provisional patent application lasts for 12 months from the filing date, after which it expires if not converted to a non-provisional application.
No. “Provisional patent” is shorthand for a provisional patent application. It is never examined and never becomes a patent by itself; it holds your filing date for 12 months while you prepare a non-provisional application.
