Provisional Application for Patent

Since June 8, 1995, the United States Patent and Trademark Office (USPTO) has offered inventors the option of filing a provisional application for patent which was designed to provide a lower-cost first patent filing in the United States and to give U.S. applicants parity with foreign applicants under the GATT Uruguay Round Agreements.

A provisional application for patent (provisional application) is a U.S. national application filed in the USPTO under 35 U.S.C. §111(b). A provisional application is not required to have a formal patent claim or an oath or declaration. Provisional applications also should not include any information disclosure (prior art) statement since provisional applications are not examined. A provisional application provides the means to establish an early effective filing date in a later filed nonprovisional patent application filed under 35 U.S.C. §111(a). It also allows the term "Patent Pending" to be applied in connection with the description of the invention.

A provisional application for patent has a pendency lasting 12 months from the date the provisional application is filed. The 12-month pendency period cannot be extended. Therefore, an applicant who files a provisional application must file a corresponding nonprovisional application for patent (nonprovisional application) during the 12-month pendency period of the provisional application in order to benefit from the earlier filing of the provisional application. However, a nonprovisional application that was filed more than 12 months after the filing date of the provisional application, but within 14 months after the filing date of the provisional application, may have the benefit of the provisional application restored by filing a grantable petition (including a statement that the delay in filing the nonprovisional application was unintentional and the required petition fee) to restore the benefit under 37 CFR 1.78.

In accordance with 35 U.S.C. §119(e), the corresponding nonprovisional application must contain or be amended to contain a specific reference to the provisional application. For nonprovisional applications filed on or after September 16, 2012, the specific reference must be included in an application data sheet. Further, a claim under 35 U.S.C. §119(e) for the benefit of a prior provisional application must be filed during the pendency of the nonprovisional application, and within four months of the nonprovisional application filing date or within sixteen months of the provisional application filing date (whichever is later). See 37 CFR 1.78.

Once a provisional application is filed, an alternative to filing a corresponding nonprovisional application is to convert the provisional application to a nonprovisional application by filing a grantable petition under 37 C.F.R. 1.53(c)(3) requesting such a conversion within 12 months of the provisional application filing date.

Converting a provisional application into a nonprovisional application (versus filing a nonprovisional application claiming the benefit of the provisional application) will have a negative impact on patent term. The term of a patent issuing from a nonprovisional application resulting from the conversion of a provisional application will be measured from the original filing date of the provisional application. By filing a provisional application first, and then filing a corresponding nonprovisional application that references the provisional application within the 12-month provisional application pendency period, a patent term endpoint may be extended by as much as 12 months.

Provisional application for patent filing date requirements

The provisional application must name all of the inventor(s). In view of the one-year grace period provided by 35 U.S.C. 102(b)(1) in conjunction with 35 U.S.C. 102(a)(1), a provisional application can be filed up to 12 months following an inventor's public disclosure of the invention. (Such a pre-filing disclosure, although protected in the United States, may preclude patenting in foreign countries.) A public disclosure (e.g., publication, public use, offer for sale) more than one year before the provisional application filing date would preclude patenting in the United States. Keep in mind that a publication, use, sale, or other activity only has to be made available to the public to qualify as a public disclosure.

A filing date will be accorded to a provisional application only when it contains a written description of the invention, complying with all requirements of 35 U.S.C. §112(a).

Although the application will be accorded a filing date regardless of whether any drawings are submitted, applicants are advised to file with the application any drawings necessary for the understanding of the invention, complying with 35 U.S.C. 113. A drawing necessary to understand the invention cannot be introduced into an application after the filing date because of the prohibition against new matter. Further, 37 CFR 1.53(c) prohibits amendments from being filed in provisional applications which are not required to comply with the patent statute and all applicable regulations.

To be complete, a provisional application must also include the filing fee as set forth in 37 CFR 1.16(d) and a cover sheet* identifying:

Cautions

  1. a corresponding nonprovisional application for patent entitled to a filing date is filed that claims the benefit of the earlier filed provisional application (unless the benefit of the provisional application was restored under 37 CFR 1.78 in which case the nonprovisional application may be filed within 14 months from provisional application filing date); or
  2. a grantable petition under 37 CFR 1.53(c)(3) to convert the provisional application into a nonprovisional application is filed.

Fee

Fees are subject to change annually. See current fees (37 CFR 1.16(d)) at www.uspto.gov. Call the USPTO Contact Center (UCC) Monday to Friday (except federal holidays) at 800-786-9199 for fee information. Payment by check or money order must be made payable to "Director of the U.S. Patent and Trademark Office."

How to file

The provisional application papers (written description and drawings), filing fee and cover sheet can be filed electronically using Patent Center or filed by mail.

Electronically Using Patent Center: The provisional application can be filed electronically only if Patent Center is used. Patent Center allows patent applications, including provisional applications, to be filed securely via the Internet. Applicants prepare documents in Portable Document Format (PDF), attach the documents, validate that the PDF documents will be compatible with USPTO internal automated information systems, submit the documents, and pay fees with real-time payment processing. When fillable Patent Center forms are used, the data entered into the forms is automatically loaded into USPTO information systems. Further information on Patent Center is available at https://www.uspto.gov/patents/apply/patent-center.

By Mail: The provisional application and filing fee can be mailed to:

Commissioner for Patents
P.O. Box 1450
Alexandria, VA 22313-1450

Features

Warnings

A provisional application automatically becomes abandoned when its pendency period expires 12 months after the provisional application filing date by operation of law. Applicants must file a nonprovisional application claiming benefit of the earlier provisional application filing date in the USPTO before the provisional application pendency period expires in order to preserve any benefit from the provisional application filing (unless the benefit of the provisional application has been restored under 37 CFR 1.78).

Beware that an applicant who publicly discloses his or her invention (e.g., publishes, uses, sells, or otherwise makes available to the public) during the 12 month provisional application pendency period may lose more than the benefit of the provisional application filing date if the 12 month provisional application pendency period expires before a corresponding nonprovisional application is filed. Such an applicant may also lose the right to ever patent the invention. See 35 U.S.C. §§102(a)(1) and (b)(1).

Independent inventors should fully understand that a provisional application will not mature into a granted patent without further submissions by the inventor. Some invention promotion firms misuse the provisional application process leaving the inventor with no patent.
