Should you file a provisional patent application now, or go straight to a non provisional patent?
The answer depends on more than cost.
It depends on how soon you plan to launch or publicly discuss it, what your budget allows, and whether delaying formal examination has strategic value.
A provisional patent application can establish an early U.S. filing date and give you up to 12 months before you need to file a corresponding non provisional application. A non provisional application begins the formal examination process and can ultimately lead to an issued patent.
The key question is not simply, “Which application is cheaper?”
It is: What does your invention and business strategy require right now?
This guide breaks down the costs, requirements, timelines, and practical differences so you can make that decision with a clearer picture of what each filing actually does.
What Is a Provisional Patent Application and How Does It Work?
A provisional patent application is a lower-formality U.S. filing that can establish an early filing date without requiring formal claims or an inventor oath or declaration. It is not examined by the USPTO and generally remains pending for 12 months.
There is no such thing as a provisional patent. You are filing a provisional patent application, not receiving a patent.
The main advantage is time. During those 12 months, you can continue developing the invention, evaluate its commercial potential, pursue funding, prepare for launch, or develop the corresponding non provisional application.
But that 12-month period is not simply a product-development buffer.
Filing before public disclosure is generally the safer approach, particularly if you may eventually seek patent protection outside the United States. A disclosure that may still be protected in the U.S. can affect your ability to obtain patent protection in foreign countries.
What Does a Provisional Patent Application Need to Include?
A provisional application generally includes:
- A written description of the invention that satisfies the applicable disclosure requirements
- Drawings when they are necessary to understand the invention
- A cover sheet or Application Data Sheet (ADS)
- Identification of all inventors
- The applicable filing fee
The provisional does not require formal claims, but that does not mean the disclosure can be vague.
The later claims in a nonprovisional application receive the benefit of the provisional’s filing date only when the provisional adequately supports the claimed subject matter.
What Happens If You Add a New Feature After Filing a Provisional?
At Emanus, we remind inventors that filing early is only part of the strategy. What you disclose in that first filing matters just as much.
Consider an inventor who files a provisional application describing a product with its core technology and several key features. During the following months, the inventor develops an important new feature that was not included in the original provisional.
When preparing the non provisional application, the inventor wants to include that new feature in the claims. However, because the original provisional did not adequately disclose or support it, the new feature cannot simply receive the provisional’s earlier filing date. The earlier date applies only to subject matter that was adequately supported by the original disclosure.
How Much Does a Provisional Patent Application Cost in 2026?
The USPTO’s 2026 provisional application filing fees are:
| Entity status | USPTO provisional filing fee |
| Undiscounted entity | $325 |
| Small entity | $130 |
| Micro entity | $65 |
Fees checked September 11, 2026.
See the official USPTO fee schedule for current fees and applicable surcharges.
These are only the government filing fees. If you work with a patent professional, preparation costs will depend on the invention’s technical complexity and how much detail needs to be developed.
What Is a Non provisional Patent Application and How Does It Work?
A nonprovisional application is the formal patent application that enters the USPTO examination process and can ultimately result in an issued patent.
For a nonprovisional utility application, the filing includes:
- A specification, including the written description, claims, and abstract
- Drawings, when necessary
- An oath or declaration
- The required filing, search, and examination fees
Is an Information Disclosure Statement Required for a Nonprovisional Patent Application?
An Information Disclosure Statement (IDS) is not a mandatory component of every nonprovisional application.
However, patent applicants, inventors, attorneys, and agents associated with the application can have a duty to disclose information that is material to patentability under 37 CFR §1.56.
Whether an IDS should be submitted, and what information should be disclosed, depends on the circumstances of the application.
How Much Does a Nonprovisional Patent Application Cost in 2026?
For a standard utility nonprovisional application, the USPTO’s basic government fees break down as follows:
|
Fee |
Undiscounted | Small Entity |
Micro Entity |
| Basic filing | $350 | $140 | $70 |
| Search | $770 | $308 | $154 |
| Examination | $880 | $352 | $176 |
| Total | $2,000 | $800 | $400 |
Additional USPTO fees can also apply, including:
- Paper or non-electronic filing fees
- Non-DOCX filing fees
- Excess independent claim fees
- Excess total claim fees
- Application-size fees
- Later prosecution and other applicable fees
What Is the Difference Between a Provisional and Non provisional Patent Application?
A provisional can establish an early filing date and give you time to decide what comes next. A non provisional begins the formal examination process.
|
Provisional |
Nonprovisional |
|
| Main purpose | Establish an early filing date | Seek formal patent protection |
| USPTO examination | No | Yes |
| Formal claims required | No | Yes |
| Initial government cost | Lower | Higher |
| Pendency | Generally 12 months | Proceeds through examination |
| Can result in an issued patent? | No, not by itself | Yes |
| Best use | Time to develop, validate, and plan | Formal patent protection and examination |
When Should You File a Provisional Patent Application?
A provisional may make sense when your invention is developed enough to describe adequately, but you still need time before committing to the full non provisional process.
You might consider a provisional when:
- You are approaching an investor meeting or product launch
- You need to establish an early U.S. filing date before public disclosure
- The product is still undergoing meaningful development
- You expect customer or investor feedback that could influence the final product
- You want more time to develop the non provisional application
- Your current patent budget favors a staged approach
The important part is that you should not wait until the end of the 12-month period to think about your non provisional.
The provisional should contain enough detail to support the subject matter you ultimately want to claim.
When Should You File a Non provisional Patent Application?
Going directly to a non provisional may make more sense when:
- The invention is already sufficiently developed and disclosed
- You are ready to pursue formal patent examination
- The market is moving quickly
- You need examination to begin without waiting for the provisional period to expire
- There is little strategic value in delaying the non provisional filing
- Your budget allows for the higher upfront filing and professional costs
A direct non provisional filing can also make sense when the invention is unlikely to change substantially and you already have a clear understanding of the protection you want to pursue.
How Do You Convert a Provisional Application Into a Non provisional Application?
Technically, you do not “convert” a provisional application into a non provisional application. Instead, you file a corresponding non provisional application within the applicable 12-month period and claim the benefit of the provisional application’s filing date.
A practical timeline looks like this:
- File: Submit a detailed provisional application.
- Develop: Refine the invention and identify meaningful improvements.
- Validate: Gather market, customer, and investor feedback.
- Prepare: Develop the non provisional application and claim strategy.
- File: Submit the non provisional application within the required period and properly claim the benefit of the provisional.
Is a Provisional Patent Application Better Than a Non provisional Patent Application?
No. Neither is universally better.
A provisional may be useful when the extra time has strategic value. If your invention is ready, your launch is approaching, or you already know what protection you want to pursue, filing directly as a non provisional may be the more sensible route.
The mistake is choosing based only on the lower filing fee.
The better question is:
What does your invention, timeline, budget, and patent strategy need at this stage?
How Do You Decide Between a Provisional and Non provisional Patent Application?
Before choosing, ask:
How Complete Is Your Disclosure?
Can you describe the invention in enough technical detail today to support the subject matter you may ultimately want to claim?
How Likely Is Your Product to Change?
Are important features, embodiments, materials, processes, or technical improvements still likely to change?
How Soon Are You Planning to Launch?
Are you planning a public launch, demonstration, sale, publication, or other disclosure soon?
Are You Planning to Discuss Your Invention With Investors?
Will you be discussing the invention with investors, partners, customers, or potential licensees before the non provisional would otherwise be filed?
Do You Plan to Seek Foreign Patent Protection?
Do you expect to seek patent protection outside the United States?
What Is Your Patent Filing Budget?
Would staging the filing make sense financially, or are you ready to invest in the non provisional now?
How Quickly Do You Want the USPTO Examination to Begin?
Would there be a strategic advantage to beginning formal USPTO examination now rather than waiting?
Your answers can help determine whether the 12-month provisional period provides meaningful strategic value or simply delays a filing you are already ready to make.
Conclusion
There is no universal answer.
A provisional may give you useful time to develop, validate, and plan, while a non provisional may be the better fit when your invention and patent strategy are already developed and you want to begin formal examination.
The most important factor is not simply the filing fee. It is whether the application you file today adequately supports the protection you may want tomorrow.

Most Common Questions
What Is a Non provisional Patent Application?
A non provisional patent application is the formal application filed with the USPTO to seek patent protection. It is examined by a patent examiner and can lead to an issued patent.
What Is the USPTO 12-Month Rule for a Provisional Patent Application?
A provisional patent application generally gives you 12 months before it expires. To seek the benefit of its filing date, you generally need to file a corresponding non provisional application within that period and properly claim the benefit of the provisional. The later claims must also be adequately supported by the provisional disclosure.
Is a Provisional Patent Application Worth Anything?
A provisional patent application can establish an early filing date and give you time to develop your invention and prepare a non provisional application. However, it is not an issued patent and does not provide enforceable patent rights by itself.
What Are the Main Types of U.S. Patents?
The three main types of U.S. patents are utility, design, and plant patents. A utility patent generally protects how an invention works or is used, while a design patent protects the ornamental design of an article and a plant patent protects certain distinct and new varieties of plants.
What Are the Disadvantages of a Provisional Patent Application?
A provisional application is not examined, does not become a patent by itself, and expires after 12 months. Its disclosure must also adequately support the claims later pursued. If important subject matter is missing from the provisional, that later-added subject matter may not receive the provisional’s earlier filing date.
Can You Sell or Transfer a Provisional Patent Application?
A provisional patent application can generally be assigned or transferred, but it is an application, not an issued patent, and does not provide enforceable patent rights by itself.
