(B) a drawing as prescribed by section 113; and

(C) an oath or declaration as prescribed by section 115.

(3) Fee, oath or declaration, and claims.— The application shall be accompanied by the fee required by law. The fee, oath or declaration, and 1 or more claims may be submitted after the filing date of the application, within such period and under such conditions, including the payment of a surcharge, as may be prescribed by the Director. Upon failure to submit the fee, oath or declaration, and 1 or more claims within such prescribed period, the application shall be regarded as abandoned.

(4) Filing date.— The filing date of an application shall be the date on which a specification, with or without claims, is received in the United States Patent and Trademark Office.

(b) Provisional Application.— (1) Authorization.— A provisional application for patent shall be made or authorized to be made by the inventor, except as otherwise provided in this title, in writing to the Director. Such application shall include—

(A) a specification as prescribed by section 112(a); and

(B) a drawing as prescribed by section 113.

(2) Claim.— A claim, as required by subsections (b) through (e) of section 112, shall not be required in a provisional application.

(3) Fee.— The application shall be accompanied by the fee required by law. The fee may be submitted after the filing date of the application, within such period and under such conditions, including the payment of a surcharge, as may be prescribed by the Director. Upon failure to submit the fee within such prescribed period, the application shall be regarded as abandoned.

(4) Filing date.— The filing date of a provisional application shall be the date on which a specification, with or without claims, is received in the United States Patent and Trademark Office.

(5) Abandonment.— Notwithstanding the absence of a claim, upon timely request and as prescribed by the Director, a provisional application may be treated as an application filed under subsection (a). Subject to section 119(e)(3), if no such request is made, the provisional application shall be regarded as abandoned 12 months after the filing date of such application and shall not be subject to revival after such 12-month period.

(6) Other basis for provisional application.— Subject to all the conditions in this subsection and section 119(e), and as prescribed by the Director, an application for patent filed under subsection (a) may be treated as a provisional application for patent.

(c) Prior Filed Application.— Notwithstanding the provisions of subsection (a), the Director may prescribe the conditions, including the payment of a surcharge, under which a reference made upon the filing of an application under subsection (a) to a previously filed application, specifying the previously filed application by application number and the intellectual property authority or country in which the application was filed, shall constitute the specification and any drawings of the subsequent application for purposes of a filing date. A copy of the specification and any drawings of the previously filed application shall be submitted within such period and under such conditions as may be prescribed by the Director. A failure to submit the copy of the specification and any drawings of the previously filed application within the prescribed period shall result in the application being regarded as abandoned. Such application shall be treated as having never been filed, unless—

(1) the application is revived under section 27; and

(2) a copy of the specification and any drawings of the previously filed application are submitted to the Director.
