A provisional application for patent is a U.S. national application for patent filed in the USPTO under 35 U.S.C. §111(b). It allows filing without a formal patent claim, oath or declaration, or any information disclosure (prior art) statement. It provides the means to establish an early effective filing date in a later filed non-provisional 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.

PROVISIONAL APPLICATION FOR PATENT
FEBRUARY 2011
BACKGROUND
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 is a U.S. national application for patent filed in the USPTO under 35 U.S.C. §111(b). It allows filing without a formal patent claim, oath or declaration, or any information disclosure (prior art) statement. It provides the means to establish an early effective filing date in a later filed non-provisional 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 (provisional application) 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 non-provisional application for patent (non-provisional application) during the 12-month pendency period of the provisional application in order to benefit from the earlier filing of the provisional application. In accordance with 35 U.S.C. §119(e), the corresponding non-provisional application must contain or be amended to contain a specific reference to the provisional application.
Once a provisional application is filed, an alternative to filing a corresponding non-provisional application is to convert the provisional application to a non-provisional 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.
However, converting a provisional application into a non-provisional 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 non-provisional 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 be made in the name(s) of all of the inventor(s). It can be filed up to 12 months following the date of first sale, offer for sale, public use, or publication of the invention, whichever occurs first. (These pre-filing disclosures, although protected in the United States, may preclude patenting in foreign countries.)
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 ¶ 1; and - any drawings necessary to understand the invention, complying with
35 U.S.C. §113.
If either of these items are missing or incomplete, no filing date will be accorded to the provisional application. 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:
- the application as a provisional application for patent;
- the name(s) of all inventors;
- inventor residence(s);
- title of the invention;
- name and registration number of attorney or agent and docket number (if applicable);
- correspondence address; and
- any U.S. Government agency that has a property interest in the application.
