Provisional vs. Non-Provisional Patent: Which Should Irvine, CA Startups File First?
In the provisional vs non-provisional patent decision, most startups file a provisional first when they need an early filing date quickly and a non-provisional first when the invention is ready and speed to grant matters. A provisional is never examined and expires after 12 months, while only a non-provisional can become a patent. See patent services in Irvine, CA or schedule a free consultation.
What Is the Real Difference in a Provisional vs Non-Provisional Patent?
A provisional application holds an early filing date for 12 months, while a non-provisional application is the one the USPTO actually examines and can grant as a patent. Under 35 U.S.C. 111(b), a provisional needs a written description and any necessary drawings, but no formal claims, oath, or information disclosure statement. The USPTO does not examine it on the merits, and it is automatically abandoned 12 months after filing. A non-provisional application must include claims, an inventor declaration, and full filing fees, and it starts the examination process that can lead to an issued patent. To keep the provisional’s filing date, you must file a non-provisional claiming its benefit within 12 months under 35 U.S.C. 119(e), with a narrow two-month restoration window if the delay was unintentional.
Is a Provisional Patent Worth Anything for a Startup?
Yes, a well-prepared provisional is worth something because it secures a priority date and lets you use the term patent pending, but it has no value as a patent by itself. It cannot be enforced against anyone, and it never turns into a patent unless you file a non-provisional in time. For a startup, the main benefits are timing and flexibility. You can lock in a filing date before a pitch, trade show, or publication, then spend up to a year testing the market, raising money, and refining the product. The 12-month period also does not count against your 20-year patent term, because the term runs from the non-provisional filing date under 35 U.S.C. 154. Investors often ask whether you have filed, and a strong provisional gives you a credible answer.
What Are the Risks of Filing a Thin Provisional Application?
The biggest risk of a thin provisional is that it may not support the claims you file later, which means you lose the early date for anything it does not describe. The USPTO states that claims in the non-provisional must be supported by the provisional’s content to receive its filing date. A one-page summary, a slide deck, or a set of photos often leaves out the details, alternatives, and data that later claims need. If a competitor files or publishes in the meantime, the gap can be costly. Biotech and supplement startups face this risk more often because their claims frequently depend on specific formulations, dosages, or test results. Treat a provisional as a draft of the full application whenever you can, and update it with new provisionals as the invention develops.
How Much Do Provisional and Non-Provisional Filings Cost at the USPTO?
A provisional costs far less in USPTO fees than a non-provisional, but the total spend depends mostly on attorney time. Under the USPTO fee schedule effective January 19, 2025, the provisional filing fee is $325 for a large entity, $130 for a small entity, and $65 for a micro entity. A utility non-provisional requires filing, search, and examination fees that total $2,000, $800, or $400, plus an issue fee of $1,290, $516, or $258 if allowed. Most startups qualify as small entities. Attorney fees for a strong provisional can approach those for a full application because the work overlaps. See our guide to patent attorney cost in Irvine, CA for national fee estimates. Key USPTO fees for large, small, and micro entities include:
- Provisional filing fee: $325, $130, or $65
- Non-provisional filing, search, and examination: $2,000, $800, or $400
- Utility issue fee: $1,290, $516, or $258
- Track One prioritized examination: $4,515, $1,806, or $903
How Does the 12-Month Deadline Affect PCT and Foreign Filing?
The same 12-month window that applies to converting a provisional also controls most foreign filing, so startups that plan to sell abroad must decide on international protection by the provisional’s first anniversary. Under 35 U.S.C. 119 and the Paris Convention framework, a later application must generally be filed within 12 months to claim the earlier priority date. Many startups file a Patent Cooperation Treaty (PCT) international application at that point, which preserves rights in many countries and delays national filings until 30 months from the priority date in the United States and most other offices, according to WIPO. Public disclosure also matters. The United States allows a one-year grace period for an inventor’s own disclosures, but many foreign countries do not, so filing before you publish or pitch publicly protects more options.
When Should Irvine, CA Startups Skip the Provisional and Use Track One?
Irvine, CA startups often skip the provisional when the invention is already complete and a granted patent would help close a funding round, a license, or a partnership sooner. In that case, filing a non-provisional with Track One prioritized examination can make sense. The USPTO states that Track One aims for a final disposition within about 12 months, compared with average utility total pendency of 27.9 months as of February 2026. Track One requires the full non-provisional fees plus the prioritized examination fee of $4,515, $1,806, or $903, and it limits the application to four independent claims, 30 total claims, and no multiple dependent claims. The USPTO raised the annual cap to 20,000 accepted requests on July 8, 2025. Read more in our guide on how long a patent takes.

Common Questions
Frequently Asked Questions About Provisional vs Non-Provisional Patents in Irvine, CA
No. The USPTO states that the 12-month pendency period cannot be extended. If you miss the deadline, you can file a new provisional, but it gets a new, later filing date. A non-provisional filed within 14 months may restore the benefit through a petition showing the delay was unintentional, but you should not plan around that safety net.
Yes. Filing a provisional application lets you use the term patent pending for 12 months, and the term remains accurate while a non-provisional is pending. It signals to competitors that a patent may issue later. You cannot sue anyone for infringement on a provisional, because no patent rights exist until a patent is granted.
No. The USPTO does not accept provisional applications for designs. If your product’s value is in its ornamental appearance, you would file a design patent application directly, which is examined on its own track. Our design patent page explains how design protection works and when it makes sense alongside a utility filing.
Often, yes. Startups frequently file follow-up provisionals as they add data, new embodiments, or improvements. A single non-provisional filed within 12 months of the earliest provisional can claim the benefit of all of them. Each new subject matter gets the date of the provisional where it first appeared, so filing updates promptly protects later improvements.
It depends on the founder’s employment agreement and California Labor Code 2870. That law generally prevents an employer from claiming an invention made entirely on the employee’s own time without company equipment, supplies, facilities, or trade secrets, unless it relates to the employer’s business or research or results from the employee’s work. Review prior agreements before you file.
No. A U.S. utility patent term generally runs 20 years from the non-provisional filing date, and the provisional period is not counted. This means filing a provisional first can push your patent’s expiration date out by up to 12 months. Converting the provisional itself into a non-provisional, instead of filing a new one, measures the term from the provisional date.
