Office Action

§Other
DETAILED ACTION Claims 10-19 are currently pending and are allowed. The closest prior art of record is EP3273797 (IDS filed 12/6/2023, foreign patent documents cite no 4), which discloses a glycerol ester composition comprising monovalerin which inhibits the gram-positive bacteria Clostridium perfringens, but fails to disclose the instantly claimed invention. Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Specification The disclosure is objected to because of the following informalities: The abstract of the disclosure is objected to because the abstract utilizes legal phraseology, specifically multiple instances of “said.” A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). Applicant is reminded of the proper language and format for an abstract of the disclosure. The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details. The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided. The disclosure is objected to because of the following informalities: The specification does not include a section for the brief description of the drawings: BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING(S): See MPEP § 608.01(f). A reference to and brief description of the drawing(s) as set forth in 37 CFR 1.74. While applicant discusses the drawings in the section entitled “EMBODIMENT EXAMPLES” there is no section entitled “BRIEF DESCRIPTION OF THE DRAWINGS.” Additionally, while Structure 1 and Structure 2 along with Figures 1-4 are discussed in the “EMBODIMENT EXAMPLES” section of the specification, as structures 1 and structure 2 are figures, the figures should be renamed Figures 1, 2, 3, 4, 5, and 6. Appropriate correction is required. Additionally, please update any reference to a structure or figure in the specification with the corrected figure number. The Preliminary Amendment filed 6 December 2023 is objected to under 35 U.S.C. 132(a) because it introduces new matter into the disclosure. 35 U.S.C. 132(a) states that no amendment shall introduce new matter into the disclosure of the invention. The added material which is not supported by the original disclosure is as follows: “which are incorporated herein by reference in their entireties.” MPEP 211.02 and MPEP 201.06(c)(IV) state the following in regard to “Incorporation by Reference” and PCT Rule 20.6, Rule 20.7 and Rule 4.18 are directed specifically to International applications: MPEP 211.02, in-part For applications filed on or after September 21, 2004, a claim under 35 U.S.C. 119(e) or 120 and 37 CFR 1.78 for benefit of a prior-filed provisional application, nonprovisional application, international application designating the United States, or international design application designating the United States that was present on the filing date of the continuation or divisional application, or the nonprovisional application claiming benefit of a prior-filed provisional application, is considered an incorporation by reference of the prior-filed application as to inadvertently omitted material, subject to the conditions and requirements of 37 CFR 1.57(b). The purpose of 37 CFR 1.57(b) is to provide a safeguard for applicants when all or a portion of the specification and/or drawing(s) is (are) inadvertently omitted from an application. See MPEP § 201.06 and 217. However, applicants are encouraged to provide in the specification an explicit incorporation by reference statement to the prior-filed application(s) for which benefit is claimed under 35 U.S.C. 119(e) or 120 if applicants do not wish the incorporation by reference to be limited to inadvertently omitted material pursuant to 37 CFR 1.57(b). See 37 CFR 1.57(c). See also MPEP §§ 217 and MPEP § 608.01(p). When a benefit claim is submitted after the filing of an application, and the later-filed application as filed did not incorporate the prior-filed application by reference, applicant cannot add an incorporation by reference statement of the prior application. An incorporation by reference statement added after an application’s filing date is not effective because no new matter can be added to an application after its filing date (see 35 U.S.C. 132(a)). See Dart Indus. v. Banner, 636 F.2d 684, 207 USPQ 273 (C.A.D.C. 1980). See also 37 CFR 1.57(b). MPEP 201.06(c)(IV), in-part 201.06(c) 37 CFR 1.53(b) and 37 CFR 1.63(d) Divisional-Continuation Procedure [R-07.2015] IV. INCORPORATION BY REFERENCE An applicant may incorporate by reference the prior application by including, in the continuing application-as-filed, an explicit statement that such specifically enumerated prior application or applications are “hereby incorporated by reference.” The statement must appear in the specification. See 37 CFR 1.57(c) and MPEP § 608.01(p). The inclusion of this incorporation by reference statement will permit an applicant to amend the continuing application to include subject matter from the prior application(s), without the need for a petition provided the continuing application is entitled to a filing date notwithstanding the incorporation by reference. For applications filed prior to September 21, 2004, the incorporation by reference statement may appear in the transmittal letter or in the specification. Note that for applications filed prior to September 21, 2004, if applicants used a former version of the transmittal letter form provided by the USPTO, the incorporation by reference statement could only be relied upon to add inadvertently omitted material to the continuation or divisional application. An incorporation by reference statement added after an application’s filing date is not effective because no new matter can be added to an application after its filing date (see 35 U.S.C. 132(a)). If an incorporation by reference statement is included in an amendment to the specification to add a benefit claim under 35 U.S.C. 120 after the filing date of the application, the amendment would not be proper. When a benefit claim under 35 U.S.C. 120 is submitted after the filing of an application, the reference to the prior application cannot include an incorporation by reference statement of the prior application. See Dart Indus. v. Banner, 636 F.2d 684, 207 USPQ 273 (C.A.D.C. 1980). 20.6 Confirmation of Incorporation by Reference of Elements and Parts (a) The applicant may submit to the receiving Office, within the applicable time limit under Rule 20.7 , a written notice confirming that an element or part is incorporated by reference in the international application under Rule 4.18 , accompanied by: (i) a sheet or sheets embodying the entire element as contained in the earlier application or embodying the part concerned; (ii) where the applicant has not already complied with Rule 17.1(a) , (b) or (b-bis) in relation to the priority document, a copy of the earlier application as filed; (iii) where the earlier application is not in the language in which the international application is filed, a translation of the earlier application into that language or, where a translation of the international application is required under Rule 12.3(a) or 12.4(a) , a translation of the earlier application into both the language in which the international application is filed and the language of that translation; and (iv) in the case of a part of the description, claims or drawings, an indication as to where that part is contained in the earlier application and, where applicable, in any translation referred to in item (iii). (b) Where the receiving Office finds that the requirements of Rule 4.18 and paragraph (a) have been complied with and that the element or part referred to in paragraph (a) is completely contained in the earlier application concerned, that element or part shall be considered to have been contained in the purported international application on the date on which one or more elements referred to in Article 11(1)(iii) were first received by the receiving Office. (c) Where the receiving Office finds that a requirement under Rule 4.18 or paragraph (a) has not been complied with or that the element or part referred to in paragraph (a) is not completely contained in the earlier application concerned, the receiving Office shall proceed as provided for in Rule 20.3(b)(i) , 20.5(b) , 20.5(c) , 20.5bis(b) or 20.5bis(c) , as the case may be. 20.7 Time Limit (a) The applicable time limit referred to in Rules 20.3(a) and (b) , 20.4 , 20.5(a) , (b) and (c) , 20.5bis(a) , (b) and (c) , and 20.6(a) shall be: (i) where an invitation under Rule 20.3(a) , 20.5(a) or 20.5bis(a) , as applicable, was sent to the applicant, two months from the date of the invitation; (ii) where no such invitation was sent to the applicant, two months from the date on which one or more elements referred to in Article 11(1)(iii) were first received by the receiving Office. (b) Where neither a correction under Article 11(2) nor a notice under Rule 20.6(a) confirming the incorporation by reference of an element referred to in Article 11(1)(iii)(d) or (e) is received by the receiving Office prior to the expiration of the applicable time limit under paragraph (a), any such correction or notice received by that Office after the expiration of that time limit but before it sends a notification to the applicant under Rule 20.4(i) shall be considered to have been received within that time limit. 4.18 Statement of Incorporation by Reference Where the international application, on the date on which one or more elements referred to in Article 11(1)(iii) were first received by the receiving Office, claims the priority of an earlier application, the request may contain a statement that, where an element of the international application referred to in Article 11(1)(iii)(d) or (e) , or a part of the description, claims or drawings referred to in Rule 20.5(a) , or an element or part of the description, claims or drawings referred to in Rule 20.5bis(a) is not otherwise contained in the international application but is completely contained in the earlier application, that element or part is, subject to confirmation under Rule 20.6 , incorporated by reference in the international application for the purposes of Rule 20.6 . Such a statement, if not contained in the request on that date, may be added to the request if, and only if, it was otherwise contained in, or submitted with, the international application on that date. The instant application is a 371 application which has an International filing date of 11 May 2022. The incorporation by reference statement is being added by way of a Preliminary Amendment filed 6 December 2023, which is after the instant application's International filing date of 11 May 2022. Therefore, the “incorporation by reference” statement being added to the instant specification by way of the Preliminary Amendment is deemed new matter. Applicant is required to cancel the new matter in the reply to this Office Action. Drawings New corrected drawings in compliance with 37 CFR 1.121(d) are required in this application because there are 6 figures present, however, they are called Structure 1 and Structure 2 along with Figures 1-4, the figures should be renamed Figures 1, 2, 3, 4, 5, and 6. Applicant is advised to employ the services of a competent patent draftsperson outside the Office, as the U.S. Patent and Trademark Office no longer prepares new drawings. The corrected drawings are required in reply to the Office action to avoid abandonment of the application. The requirement for corrected drawings will not be held in abeyance. INFORMATION ON HOW TO EFFECT DRAWING CHANGES Replacement Drawing Sheets Drawing changes must be made by presenting replacement sheets which incorporate the desired changes and which comply with 37 CFR 1.84. An explanation of the changes made must be presented either in the drawing amendments section, or remarks, section of the amendment paper. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). A replacement sheet must include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of the amended drawing(s) must not be labeled as “amended.” If the changes to the drawing figure(s) are not accepted by the examiner, applicant will be notified of any required corrective action in the next Office action. No further drawing submission will be required, unless applicant is notified. Identifying indicia, if provided, should include the title of the invention, inventor’s name, and application number, or docket number (if any) if an application number has not been assigned to the application. If this information is provided, it must be placed on the front of each sheet and within the top margin. Annotated Drawing Sheets A marked-up copy of any amended drawing figure, including annotations indicating the changes made, may be submitted or required by the examiner. The annotated drawing sheet(s) must be clearly labeled as “Annotated Sheet” and must be presented in the amendment or remarks section that explains the change(s) to the drawings. Timing of Corrections Applicant is required to submit acceptable corrected drawings within the time period set in the Office action. See 37 CFR 1.85(a). Failure to take corrective action within the set period will result in ABANDONMENT of the application. If corrected drawings are required in a Notice of Allowability (PTOL-37), the new drawings MUST be filed within the THREE MONTH shortened statutory period set for reply in the “Notice of Allowability.” Extensions of time may NOT be obtained under the provisions of 37 CFR 1.136 for filing the corrected drawings after the mailing of a Notice of Allowability.
