Claim Required for Design Application Filing Date
Note:
A claim is necessary to establish a filing date for design applications and nonprovisional applications filed before December 18, 2013.

Therefore, in an application filed under 35 U.S.C. 111(a) prior to December 18, 2013 and in a design application, a claim is a statutory requirement for according a filing date to the application. 35 U.S.C. 171 makes 35 U.S.C. 112 applicable to design applications. 35 U.S.C. 162 specifically requires the specification in a plant patent application to contain a claim, but a claim is not required for receiving a filing date for plant patent applications filed on or after December 18, 2013. In addition, 35 U.S.C. 111(b)(2) provides that “[a] claim, as required by subsections (b) through (e) of section 112, shall not be required in a provisional application.” Thus, only design applications and nonprovisional applications filed prior to December 18, 2013 that are filed without at least one claim are incomplete and not entitled to a filing date.

Claim Not Required for Plant Patents Filed After Dec 18, 2013
Note:
For plant patent applications filed on or after December 18, 2013, a claim is not required to receive a filing date.

Therefore, in an application filed under 35 U.S.C. 111(a) prior to December 18, 2013 and in a design application, a claim is a statutory requirement for according a filing date to the application. 35 U.S.C. 171 makes 35 U.S.C. 112 applicable to design applications. 35 U.S.C. 162 specifically requires the specification in a plant patent application to contain a claim, but a claim is not required for receiving a filing date for plant patent applications filed on or after December 18, 2013. In addition, 35 U.S.C. 111(b)(2) provides that “[a] claim, as required by subsections (b) through (e) of section 112, shall not be required in a provisional application.” Thus, only design applications and nonprovisional applications filed prior to December 18, 2013 that are filed without at least one claim are incomplete and not entitled to a filing date.

Claims Not Required for Design Applications and Nonprovisional Pre-2013
Note:
This rule states that claims are not required in design applications and nonprovisional applications filed before December 18, 2013.

Therefore, in an application filed under 35 U.S.C. 111(a) prior to December 18, 2013 and in a design application, a claim is a statutory requirement for according a filing date to the application. 35 U.S.C. 171 makes 35 U.S.C. 112 applicable to design applications. 35 U.S.C. 162 specifically requires the specification in a plant patent application to contain a claim, but a claim is not required for receiving a filing date for plant patent applications filed on or after December 18, 2013. In addition, 35 U.S.C. 111(b)(2) provides that “[a] claim, as required by subsections (b) through (e) of section 112, shall not be required in a provisional application.” Thus, only design applications and nonprovisional applications filed prior to December 18, 2013 that are filed without at least one claim are incomplete and not entitled to a filing date.

Claims Must Be Included In Design Application
Note:
Design applications must include at least one claim to receive a filing date and avoid a Notice of Incomplete Application.

If a nonprovisional application filed prior to December 18, 2013 or a design application does not contain at least one claim, a “Notice of Incomplete Application” will be mailed to the applicant(s) indicating that no filing date has been granted and setting a period for submitting a claim. The filing date will be the date of receipt of at least one claim. See In re Mattson, 208 USPQ 168 (Comm’r Pat. 1980). In applications filed before September 16, 2012, an oath or declaration in compliance with pre-AIA 37 CFR 1.63 and pre-AIA 37 CFR 1.64 referring to the claim being submitted is also required.

Filing Date Is Based on Receipt of Claims
Note:
The filing date for an application is determined by the receipt of at least one claim, unless it does not contain a compliant oath or declaration.

If a nonprovisional application filed prior to December 18, 2013 or a design application does not contain at least one claim, a “Notice of Incomplete Application” will be mailed to the applicant(s) indicating that no filing date has been granted and setting a period for submitting a claim. The filing date will be the date of receipt of at least one claim. See In re Mattson, 208 USPQ 168 (Comm’r Pat. 1980).

Application With Cancelled Claims Treated As One Claim
Note:
For fee calculation purposes, an application with cancelled claims is treated as containing a single claim.

If a nonprovisional application filed prior to December 18, 2013 or a design application is accompanied by a preliminary amendment which cancels all claims without presenting any new or substitute claims, the Office will disapprove such an amendment. See 37 CFR 1.115(b)(1) and Exxon Corp. v. Phillips Petroleum Co., 265 F.3d 1249, 60 USPQ2d 1368 (Fed. Cir. 2001). Thus, the application will not be denied a filing date merely because such a preliminary amendment was submitted on filing. For fee calculation purposes, the Office will treat such an application as containing only a single claim.

Conversion of Provisional to Nonprovisional Application Without Claims Allowed
Note:
An applicant can convert a provisional application filed on or after June 8, 1995, into a nonprovisional application without claims by filing a petition within 12 months from the date of deposit.

As 37 CFR 1.53(c)(2) permits the conversion of an application filed under 35 U.S.C. 111(a) to an application under 35 U.S.C. 111(b), an applicant in an application, other than for a design patent, filed under 35 U.S.C. 111(a) on or after June 8, 1995, without at least one claim has the alternative of filing a petition under 37 CFR 1.53(c)(2) to convert such application into an application under 35 U.S.C. 111(b), which does not require a claim to be entitled to its date of deposit as a filing date. Such a petition, however, must be filed prior to the expiration of 12 months after the date of deposit of the application under 35 U.S.C. 111(a), and comply with the other requirements of 37 CFR 1.53(c)(2). See MPEP § 601.01(c). For nonprovisional applications filed under 35 U.S.C. 111(a) on or after December 18, 2013, there is no need to request conversion to a provisional application because such applications do not require presentation of at least one claim to obtain a filing date.

Note:
The specification must provide a complete written description of the invention, while claims must distinctly point out the subject matter regarded as the applicant's invention.

For nonprovisional applications filed prior to December 18, 2013 or design applications, the applicable version of 35 U.S.C. 111(a)(2) requires that an application for patent include, inter alia, “a specification as prescribed by section 112,” and the applicable version of 35 U.S.C. 111(a)(4) provides that the “filing date of an application shall be the date on which the specification and any required drawing are received in the Patent and Trademark Office.” 35 U.S.C. 112(a) provides, in part, that “[t]he specification shall contain a written description of the invention,” and 35 U.S.C. 112(b), provides that “[t]he specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.” Also, the Court of Appeals for the Federal Circuit stated in Litton Systems, Inc. v.

A claim is required in design applications to establish a filing date, as mandated by 35 U.S.C. 171 making 35 U.S.C. 112 applicable.

Therefore, in an application filed under 35 U.S.C. 111(a) prior to December 18, 2013 and in a design application, a claim is a statutory requirement for according a filing date to the application. 35 U.S.C. 171 makes 35 U.S.C. 112 applicable to design applications. 35 U.S.C. 162 specifically requires the specification in a plant patent application to contain a claim, but a claim is not required for receiving a filing date for plant patent applications filed on or after December 18, 2013. In addition, 35 U.S.C. 111(b)(2) provides that “[a] claim, as required by subsections (b) through (e) of section 112, shall not be required in a provisional application.” Thus, only design applications and nonprovisional applications filed prior to December 18, 2013 that are filed without at least one claim are incomplete and not entitled to a filing date.

Note:
A preliminary amendment that cancels all claims without presenting new or substitute claims is not permitted for nonprovisional applications filed before December 18, 2013, or design applications.

If a nonprovisional application filed prior to December 18, 2013 or a design application is accompanied by a preliminary amendment which cancels all claims without presenting any new or substitute claims, the Office will disapprove such an amendment.
