Protecting your intellectual property begins with understanding the tools available to safeguard your innovation. Patents grant inventors exclusive rights in exchange for publicly disclosing their creations. For many innovators, a provisional patent application can serve as a strategic first step, providing limited temporary protection. At the same time, you can refine your invention or prepare a full patent application. A Boynton Beach patent lawyer at The Lomnitzer Firm P.A. can help you evaluate your options and design a plan that preserves your competitive edge.
Since 1995, the U.S. Patent and Trademark Office (USPTO) has allowed inventors to file provisional patent applications. The purpose of this measure is to give inventors a patent filing option in the United States that is less costly, similar to what foreign applicants are entitled to under applicable international law.
35 U.S.C. §111(b) authorizes the filing of a provisional patent application with the USPTO. A provisional patent application does not require a formal patent claim or an oath or declaration. These applications also should not contain any information disclosure (prior art) statement.
Aside from its lower cost and relative simplicity, filing a provisional patent application allows an inventor to establish an early effective filing date when he or she later files a nonprovisional patent application. A provisional patent application, once filed with the USPTO, also allows the inventor to add the words “Patent Pending” to the description of the invention.
A provisional patent application must contain a written description of the invention that follows all requirements outlined in 35 U.S.C. §112(a). It also must name all inventor(s) affiliated with the invention.
While inventors are not required to submit drawings with a provisional patent application, inventors should submit drawings that are needed to understand the invention with the provisional patent application, because they will be unable to introduce them later. Inventors cannot introduce a drawing into a provisional patent application after the filing date due to the prohibition on new matter.
Finally, a provisional patent application must include the required filing fee, as well as a cover sheet that includes:
A provisional patent application remains in effect for 12 months from the date the inventor files it with the USPTO. Neither the inventor nor the USPTO can extend the pendency period beyond 12 months. Therefore, to maintain the benefit of the earlier filing date that the provisional application offers, the inventor must file a nonprovisional application for patent concerning the invention during the 12-month pendency period.
The only exception to this rule is for an inventor who files a nonprovisional application more than 12 months after the provisional application filing date, but less than 14 months after that date. In that case, the inventor can restore the benefit of the provisional patent application by filing a grantable petition, along with a statement of unintentional delay, and paying the required fee. Furthermore, the nonprovisional application must contain a specific reference to the provisional application on an application data sheet.
Furthermore, claims under 35 U.S.C. §119(e) for the benefit of prior provisional applications must be filed either:
Alternatively, inventors can convert a provisional application to a nonprovisional application by filing a grantable petition requesting a conversion. This filing must occur within 12 months of the provisional application filing date. While the conversion request is a legally valid option, it does negatively affect the patent term. In a conversion, the patent term is measured from the original filing date of the provisional application. On the other hand, filing a nonprovisional application referencing a provisional application within the 12-month pendency period can extend the patent term by up to 12 months.
Inventors can file a provisional patent application up to 12 months following their public disclosure of the invention. However, doing so may eliminate the potential to obtain a patent for the invention outside the U.S. However, suppose the inventor publicly discloses the invention more than one year before filing a provisional patent application with the USPTO, whether through a sale, publication, or use. In that case, the inventor may not be able to patent the invention in the U.S.
A provisional patent application allows inventors to secure an early filing date while giving them up to 12 months to refine the invention or seek funding before filing a non-provisional application. It can be a cost-effective way to establish priority without immediately committing to the full patent process.
No, a provisional patent application only applies in the United States. If you plan to seek patent protection in other countries, you will need to follow the laws for filing for patents in those countries within the required timeframes. Public disclosure before filing can limit these options.
If you don’t file a non-provisional application within 12 months of the provisional application filing, your priority date is lost, and the provisional application expires. In this case, you’ll need to start over, and any public disclosures made before the new filing could jeopardize your ability to patent the invention. However, there is a limited exception that allows you to file a restoration of a provisional application under some circumstances within 14 months of the provisional application filing.
Securing your intellectual property is one of the most important steps you can take to protect your business and innovation. A provisional patent offers inventors a valuable opportunity to establish an early filing date while giving them time to refine their invention or prepare a full patent application. However, navigating the complexities of patent law requires careful planning and strategic guidance.
