A request to convert an application under 37 CFR 1.53(b) to a provisional application requires filing the conversion request and paying the processing fee as set forth in 37 CFR 1.17(q).

An application filed under 37 CFR 1.53(b) may be converted to a provisional application in accordance with the procedure described in 37 CFR 1.53(c)(2).

The provisional application filing fee (37 CFR 1.16(d)) and the surcharge set forth in 37 CFR 1.16(g) are also required, although these fees do not need to be paid with the request for conversion.

Filing of the request in the nonprovisional application is required prior to the abandonment of the 37 CFR 1.53(b) application, the payment of the issue fee, or the expiration of 12 months after the filing date of the 37 CFR 1.53(b) application, whichever event is earlier. The grant of any such request does not entitle applicant to a refund of the fees properly paid in the application filed under 37 CFR 1.53(b).

Provisional Conversion to Nonprovisional Application Requirement
Note:
An application filed under 37 CFR 1.53(c) must follow specific procedures to convert to a nonprovisional application, including filing a conversion request and paying required fees.

An application filed under 37 CFR 1.53(c) may be converted to a nonprovisional application in accordance with the procedure described in 37 CFR 1.53(c)(3). Applicants should carefully consider the patent term consequences of requesting conversion rather than simply filing a nonprovisional application claiming the benefit of the filing date of the provisional application under 35 U.S.C. 119(e). Claiming the benefit of the provisional application under 35 U.S.C. 119(e) is less expensive and will result in a longer patent term. The procedure requires the filing of a request in the provisional application for the conversion of the provisional application to a nonprovisional application and the fee set forth in 37 CFR 1.17(i). The nonprovisional application resulting from conversion of a provisional application must also include the basic filing fee, search fee, and examination fee for the nonprovisional application. In addition, if the provisional application was not filed with an executed oath or declaration and the appropriate fees for a nonprovisional application, the surcharge set forth in 37 CFR 1.16(f) is required. Furthermore, an inventor’s oath or declaration is required to be filed in accordance with 37 CFR 1.53(f) if the provisional application was filed on or after September 16, 2012 or pre-AIA 37 CFR 1.53(f) if the provisional application was filed prior to September 16, 2012. See MPEP § 601.01(a). Filing of the request for conversion in the provisional application is required prior to the abandonment of the provisional application or the expiration of 12 months after the filing date of the 37 CFR 1.53(c) application, whichever event is earlier. The grant of any such request does not entitle applicant to a refund of the fees properly paid in the application filed under 37 CFR 1.53(c).
