Office Action

§112 §DOUBLEPATENT §DP
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 . DETAILED ACTION Claims 1-4, 6 and 8-18 are pending in the instant application. Election/Restrictions Applicant’s election without traverse of the species of Chemical Formula 2-1 (n is an integer of 1 to 4), calcium hypochlorite as the metal hypohalite and ruthenium chloride as the ruthenium catalyst in the reply filed on January 8, 2026 is acknowledged. The requirement is still deemed proper and is therefore made FINAL. Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The Examiner has considered the Information Disclosure Statement filed on April 26, 2023. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Specification The disclosure is objected to because of the following informalities: the labeling of the drawing is not in accordance with 37 CFR 1.84(u)(1), (u) Numbering of views. (1) The different views must be numbered in consecutive Arabic numerals, starting with 1, independent of the numbering of the sheets and, if possible, in the order in which they appear on the drawing sheet(s). Partial views intended to form one complete view, on one or several sheets, must be identified by the same number followed by a capital letter. View numbers must be preceded by the abbreviation "FIG." Where only a single view is used in an application to illustrate the claimed invention, it must not be numbered and the abbreviation "FIG." must not appear. in that only a single figure has been filed. See, for example, paragraph [66] on page 13 and paragraphs [145]-[148] and [150] on pages 28-29 of the instant specification and the single drawing. Appropriate correction is required. Specification The disclosure is objected to because of the following informalities: the Preliminary Amendment filed April 26, 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: the phrase “which is incorporated by reference for all purposes as if fully set forth herein”. 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-08.2017] 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) or 20.5(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), and 20.6(a) shall be: (i) where an invitation under Rule 20.3(a) or 20.5(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) 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 December 18, 2020. See a partial capture of the BIB sheet of the instant application below. PNG media_image1.png 422 602 media_image1.png Greyscale Specifically, PCT/KR2020/018653 was filed without an “incorporation by reference” statement to the earlier application filed in Korea on October 27, 2020. Then, Applicant filed a 371 of the PCT and attempted to amend the specification to include the “incorporation by reference” statement via a preliminary amendment filed April 26, 2023, which is after the instant application's International filing date of December 18, 2020. This is considered new matter. MPEP 201.06(c): “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)).” Further, in Box VI of the PCT request form, R0/101, there is a statement regarding “incorporation by reference” which basically fulfills the written notification regarding “incorporation by reference” when the document is signed. This satisfies the written notice according to Rule 4.18 but does not satisfy the conditions of PCT Rule 20.6 (a)(i)-(iv). In the PCT, Applicant is not required to explicitly state “incorporation by reference” within the PCT Specification (description pages). However, “incorporation by reference” in the PCT must be verified per PCT Rule 20.6 (a)(i)-(iv) for incorporating specific documents which were inadvertently left out of the PCT disclosure and Applicant has only a limited amount of time to explicitly indicate, during PCT prosecution, what the missing part(s) are and to submit those missing parts into the PCT file. Once they are in the file and if they have complied with PCT Rule 20.6 (a)(i)-(iv), the additional sheets, added by “incorporation by reference” will be stamped “incorporation by reference” by WIPO. Therefore, the entirety of the PCT application, including any missing parts added by “incorporation by reference” in the PCT prosecution will be a part of the National Stage application. Therefore, the rules and requirements surrounding “incorporation by reference” relating to PCT are different than the “incorporation by reference” in US cases, and even if they did incorporate something by reference in the PCT e.g., a page of the specification from a foreign priority document, this does not provide them “incorporation by reference” to the entire foreign priority document. Therefore, inserting “incorporation by reference” into the disclosure on or after the National Stage US filing date would be new matter. For all the reasons given above, 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. This objection to the specification can be overcome by deleting the phrase “which is incorporated by reference for all purposes as if fully set forth herein” from the instant specification. Claim Objections Claims 1, 12 and 16 are objected to because of the following informalities: in claim 1, line 2 of the claim, the phrase “one or more selected from compounds represented by” should be changed to “a compound selected from”; in claim 1, line 3 of the claim, the phrase “one or more selected from compounds represented by” should be changed to “a compound selected from”; in claim 12, line 1 of the claim, “the” should be added before “reaction”; and in claim 16, line 2 of the claim, the phrase “one or more selected from compounds represented by” should be changed to “a compound selected from”. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-4, 6 and 8-18 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Currently amended claim 1 is confusing because of the phrase “when n is an integer from 1 to 4” (page 4, line 1). Claim 1 has been amended whereby variable n now can only represent 1 to 4 (see the next to the last line of page 3). As a result, the presence of the phrase “when n is an integer from 1 to 4” is confusing. Therefore, claim 1 is indefinite. This rejection can be overcome by deleting the phrase “when n is an integer from 1 to 4” from claim 1. Claims dependent on claim 1 which do not resolve the problem in claim 1 are also found indefinite. Claim 12 is unclear because of the phrase “temperature maintains a dropping temperature”. Either the reaction temperature is maintained or the reaction temperature is being reduced. Therefore, claim 12 is indefinite. Clarification is required. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claims 1-4, 6 and 8-18 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-18 of copending Application No. 18/034,025 (reference application), US 2023/0391743. Although the claims at issue are not identical, they are not patentably distinct from each other because copending Application No. 18/034,025 also claims a method of preparing an organosulfur compound (such as PNG media_image2.png 108 84 media_image2.png Greyscale ) comprising reacting a compound such as PNG media_image3.png 106 74 media_image3.png Greyscale with a metal hypohalite (such as calcium hypohalite – see claim 7) under a ruthenium catalyst (such as ruthenium chloride) in a mixed solvent containing water and an organic solvent (such as methylene chloride – see claim 2) at a reaction temperature between 0 to 25 oC (see claim 12) and a pH of 7 to 9 (see claim 15) and wherein the reaction is terminated by adding a quenching reagent (such as hydrogen peroxide – see claims 17 and 18). The instant application and copending Application No. 18/034,025 share at least one common inventor (i.e., Jong Jin Ha). The instant application is not related to copending Application No. 18/034,025 and thus, no 35 USC 121 shield exists here. See MPEP §804.01. Therefore, the claims in copending Application No. 18/034,025 anticipate and/or render obvious the instant claimed invention. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. NOTE: Applicant’s attention is directed to MPEP §804(I)(B)(1)(b)(ii) (reproduced below in-part), (ii) Application under examination has the same patent term filing date If both the application under examination and the reference application have the same patent term filing date, the provisional nonstatutory double patenting rejection made in each application should be maintained until it is overcome. Provisional nonstatutory double patenting rejections are subject to the requirements of 37 CFR 1.111(b). Thus, applicant can overcome a provisional nonstatutory double patenting rejection by filing a reply that either shows that the claims subject to the rejection are patentably distinct from the claims of the reference application, or includes a compliant terminal disclaimer under 37 CFR 1.321 that obviates the rejection. If the reply is sufficient, the examiner will withdraw the nonstatutory double patenting rejection in the application in which it was submitted. and MPEP §1490(VI)(D)(2)(b) (reproduced below in-part), which states the following in regard to provisional nonstatutory obviousness-type double patenting rejections. (b) Application under Examination Has the Same Patent Term Filing Date If both the application under examination and the reference application have the same patent term filing date, the provisional nonstatutory double patenting rejection made in each application should be maintained until it is overcome. Provisional nonstatutory double patenting rejections are subject to the requirements of 37 CFR 1.111(b). Thus, applicant can overcome a provisional nonstatutory double patenting rejection by filing a reply that either shows that the claims subject to the rejection are patentably distinct from the claims of the reference application or includes a compliant terminal disclaimer in the application under 37 CFR 1.321 that obviates the rejection. If the reply is sufficient, the examiner will withdraw the nonstatutory double patenting rejection in the application in which it was submitted. The teachings in the three X references cited on the International Search Report for PCT/KR2020/18653 have been considered. The three X references are KR 10-2080198, KR 10-1991-0003712 and Rist et al. The instant specification discloses various comparison showings such as performing the reaction without water (as taught in KR 10-2080198) and using sodium hypochlorite instead of calcium hypochlorite as instantly claimed. Example 1 and Comparative Example 1 on pages 46-48 of the instant specification persuasively show that the yield of the product produced is higher when water (as required in the instant claims) is used in the process. Although, Le Roy et al. {US Patent 5,116,999 – same patent family as KR 10-1991-0003712} teach that either sodium hypochlorite or calcium hypochlorite can be used in the process, all of the examples use sodium hypochlorite. Rist et al. use sodium hypochlorite in his process. Table 1 on pages 50-51 of the instant specification persuasively shows that the yield of the product produced is higher when calcium hypochlorite (as required in the instant currently amended claims) is used in the process. Therefore, the instant claimed invention is free of the prior art of record. Reminder to Applicant As a reminder, Applicant should specifically point out the support in the original disclosure {i.e., page number(s) and line number(s)} for any new claims or amended claims and for any amendments made to the disclosure. Making generic statements such as “all amendments are fully supported in the originally filed disclosure or the originally filed claims” without specifying page numbers and originally filed claim numbers are insufficient.
