Key Takeaways

  • A provisional patent application provides a low-cost way to secure a filing date but must be followed by a non-provisional patent within one year.
  • Patent conversion refers to transitioning a provisional application into a non-provisional one, either by direct filing or a formal conversion request.
  • While provisional applications don’t require formal claims or prior art disclosures, they must be sufficiently detailed to support future claims.
  • Mistakes in the provisional application, like inadequate disclosure or vague language, can undermine the value of the subsequent patent.
  • Strategic use of the one-year window can help refine inventions, assess market interest, and seek funding.
  • Once filed, a non-provisional application must align closely with the content of the provisional filing to retain the earlier priority date.

Converting a provisional patent to full patent requires filing a non-provisional patent application and paying the required fees. Failing to convert your provisional patent before it expires means you will lose protections for your invention.

Provisional Patent Application Facts

Provisional patents have only been available since 1995. Before this point, inventors needed build and test their invention and then file a full patent application to protect their ideas before presenting them to potential investors. While this did offer protections to inventors, it was very time consuming and not always practical.

Now that provisional patents are available, inventors can protect their ideas without having to spend the money or effort necessary for a full patent. Once a provisional patent application has been filed, an invention will be protected for a one-year period. This one-year window is commonly referred to as a pendency period.

The pendency period cannot be extended for any reason. Once this one-year period has expired, the inventor will lose their patent protections. To maintain patent protections, the inventor would need to file a non-provisional patent application before the pendency period has ended. Although the term “provisional patent” is frequently used, there is no such thing in reality. When people say provisional patent, what they are talking about is a provisional patent application.

Filing a provisional patent application is the initial step in the patent process, and while filing this application will not provide you with an actual patent, it will give you some protections. Once your provisional patent application has been accepted, your invention will receive patent pending status, and you will have protections for one year.

Provisional patent applications consist of several items:

  • A specification that outlines how the invention can be made and used.
  • Drawings that are meant to clarify the specification.
  • Your payment and contact information listed on a cover sheet.

When an inventor wants to find someone to manufacture their invention, or if they are interested in testing the commercial waters, they will protect their idea from theft by filing a provisional patent application. Creating a provisional patent application is relatively easy, and once you have your application in order, you can visit the USPTO website to submit online.

Benefits and Limitations of a Provisional Patent Application

Provisional applications are a strategic tool for inventors, especially startups and entrepreneurs. They offer several benefits:

Advantages:

  • Establishes an early filing date: This is crucial in a first-to-file system.
  • Lower cost: Filing fees are significantly less than non-provisional applications.
  • Simplified requirements: No formal patent claims, oath, or declaration is required.
  • Patent pending status: You can mark your invention as "patent pending," which can deter competitors and attract investors.
  • One-year development window: Provides time to refine the invention, explore commercialization, or evaluate its market potential.

Limitations:

  • Non-renewable: The one-year pendency period cannot be extended.
  • No actual patent rights: A provisional application does not result in an issued patent or enforceable rights.
  • Insufficient detail can jeopardize patent conversion: If the provisional lacks adequate disclosure, you may not be able to claim the earlier priority date in the non-provisional application.

Steps for Filing your Application

Filing a provisional patent application is much easier than filing for a non-provisional patent. From the first time you use, sale, publish, or offer your invention for sale, you will have one year to file your provisional patent application.

If you want a filing date for your invention, your provisional patent application needs to include the following:

  • The required filing fee.
  • A full description covering how your invention can be made and how it should be used.
  • Drawings that are necessary to understand your invention.

Tips for Drafting a Strong Provisional Application

Although a provisional application is less formal, it should still be written with precision and care. To strengthen your patent conversion later, consider the following:

  • Include detailed descriptions: Use specific language to explain the invention's structure, function, and use.
  • Incorporate quality drawings: Visuals help clarify your invention and support the written description.
  • Describe multiple embodiments: If there are alternative configurations, include them to broaden protection later.
  • Avoid vague terminology: General or overly broad language may not hold up in a non-provisional review.
  • Anticipate future claims: Ensure the provisional includes enough information to support potential claims in your full application.

Poorly drafted provisional applications are a common pitfall and may render the priority date useless during patent examination.

Converting Provisional Patent to Full Patent

After you have successfully filed your provisional patent application, you will have one year to file for a non-provisional patent. This will allow you to claim the earlier filing date included on provisional application as the invention date.

You can claim the earlier filing date two basic ways. First, you will file your non-provisional patent application, and in this application, you will claim the filing date of the provisional patent application. Second, you can petition that your provisional patent application be converted to a full patent. You will need to file all required materials if you choose the latter option.

While either option will convert your provisional patent application to a non-provisional application, the length of your patent will defer. If you choose the first option, your patent's term will be based on your provisional patent application filing date. Choosing the second option means the term of your patent will be measured by the non-provisional patent application filing date.

With the second option, the length of your patent term will be a year shorter than with the first method. Essentially, choosing the first option means you will have an additional year of patent protections. If you file your non-provisional application within a year of filing your provisional application, you must be sure to reference the provisional patent application. The USPTO will check to make sure that both applications describe the exact same invention before they will approve your full patent.

What Happens If You Miss the One-Year Deadline?

Failing to file a non-provisional application within one year of your provisional filing date means:

  • You lose the benefit of the early filing date.
  • Your invention may become part of the public domain if it was disclosed during the pendency period.
  • Subsequent applications are treated as new, and any intervening disclosures or sales may act as prior art, potentially blocking patentability.

There are no grace periods or extensions for provisional applications, making strict adherence to deadlines essential.

Key Considerations for Patent Conversion

When preparing for patent conversion, it's essential to understand how the provisional application will influence the full patent:

  • Claim Support: The non-provisional must be fully supported by the provisional. If you introduce new material, you may lose the benefit of the earlier date for those parts.
  • Timing is critical: You must file your non-provisional before the one-year expiration. Missing this deadline can mean starting the process from scratch.
  • Global implications: If you plan to seek international protection through the Patent Cooperation Treaty (PCT), the U.S. provisional can serve as a priority application.
  • Strategic filing: Consider whether to file a single robust non-provisional or multiple targeted applications that trace back to the same provisional filing date.

While you can file a direct "conversion" by requesting the USPTO to treat the provisional as a non-provisional, this method is less common because it shortens the patent term by one year and offers no substantive benefit over filing a new non-provisional application that claims priority.

Frequently Asked Questions

  1. What is patent conversion?
    Patent conversion refers to the process of turning a provisional patent application into a non-provisional (full) patent application within one year.
  2. Can I extend the one-year deadline for converting my provisional patent?
    No, the USPTO does not allow extensions. If you miss the deadline, you lose the priority date and must refile.
  3. What should a provisional application include to ensure a smooth conversion?
    It should contain a thorough description of the invention, necessary drawings, and support for any future claims you plan to make.
  4. Is it better to convert or file a new non-provisional application?
    Most applicants file a new non-provisional claiming the benefit of the provisional date rather than converting directly, as it preserves a longer patent term.
  5. Can I file multiple non-provisional applications from a single provisional?
    Yes, as long as each non-provisional is filed within one year and fully supported by the original provisional content.
