This is a non-final Office action responsive to the reply filed on 07/16/2025. Claims 1, 2, 4 and 12-16 have been amended. Claims 7, 8, 17 and 18 have been canceled. Claims 1-6, 9-16, 19 and 20 are pending. Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 07/16/2025 has been entered. Claim Objections Claims 1 and 12 are objected to because of the following informalities: Claim 1, line 30 “said linear arrangement” should be - - said linear arrangement of securement holes - -. Claim 12, line 28 “said linear arrangement” should be - - said linear arrangement of securement holes - -. 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 1-6, 9-16, 19 and 20 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. Claim 1 recites the limitation "one rearmost securement hole" in line 29. Is not clear how only “one rearmost securement hole” can be expose by the interconnection sheet and fill by the rear stop at the same time. Claim 12 recites the limitation "one rearmost securement hole" in line 27. Is not clear how only “one rearmost securement hole” can be expose by the interconnection sheet and fill by the rear stop at the same time. Claims 2-6, 9-11, 13-16, 19 and 20 are rejected as being dependent upon a rejected claim. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1, 2, 4-6, 9, 12-15, 16 and 19 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Okada (CN 101023823A cited by applicant). Regarding claim 1, Okada discloses a waterproof slide fastener comprising: left and right fastener stringers including left and right waterproof tapes and left and right rows of fastener elements where the fastener elements are arranged, the left and right rows of fastener elements secured to side-edges of the left and right waterproof tapes, and each of the left and right waterproof tapes including a row of securement holes (9) including a linear arrangement of securement holes at a predetermined pitch, each of the left and right waterproof tapes having upper and lower surfaces (see annotated Figs. 2 and 4; and Fig. 16); a slider (34) that moves frontward to engage and rearward to disengage the fastener elements of said left and right rows of fastener elements (see Fig. 1 and annotated Figs. 2 and 4); an interconnection sheet that joins the left and right waterproof tapes in a rear end of the waterproof slide fastener, the interconnection sheet selectively formed on the lower surfaces of the left and right waterproof tapes without being formed on the upper surfaces of the left and right waterproof tapes (see annotated Figs. 2 and 4); and a rear stop arranged at a rear contiguous position of the left and right rows of fastener elements, the rear stop partially covering the interconnection sheet (see annotated Figs. 2 and 4), wherein the linear arrangement of securement holes of the row of securement holes in each of the left and right waterproof tapes is divided into a multiplicity of securement holes and one rearmost securement hole arranged at a rearmost position in said linear arrangement and rearward of the multiplicity of securement holes, respective ones of the securement holes of said multiplicity of securement holes filled by respective ones of the fastener elements, no securement hole being arranged rearward of the rearmost securement hole (see annotated Figs. 2 and 4; and Fig. 16), and wherein the interconnection sheet is arranged to expose the rearmost securement hole (9) in at least one of the left and right waterproof tapes, and the rear stop is arranged to fill said rearmost securement hole (9) in at least one of the left and right waterproof tapes (see annotated Figs. 2 and 4). Regarding claim 2, Okada discloses, wherein the rear stop includes an upper portion and a lower portion which are arranged at upper and lower sides of the left and right waterproof tapes, and the upper portion and the lower portion are interconnected one another via a plurality of plugs only, the plurality of plugs respectively filling the rearmost securement holes in both of the left and right waterproof tapes (see annotated Fig. 4).

PNG media_image1.png 492 724 media_image1.png Greyscale PNG media_image2.png 424 463 media_image2.png Greyscale Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim 3 is rejected under 35 U.S.C. 103 as being unpatentable over Okada (CN 101023823A cited by applicant), in view of Takazawa et al. (US Publication No. 2003/0115724). Regarding claim 3, Okada discloses the claimed invention except for a pinhole is formed in the lower portion of the rear stop, the pinhole extending to reach the interconnection sheet. However, Takazawa et al. teaches a pinhole (15) is formed in the lower portion of the rear stop (6a), the pinhole extending to reach the interconnection sheet (3b) (see Fig. 4). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to have a pinhole on the rear stop in order to fill resin flow directly into the interconnection sheet during injecting molding process. Claims 10, 11 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Okada (CN 101023823A cited by applicant), in view of Kayahara et al. (US Publication No. 2021/0007447 cited by applicant). Regarding claim 10, Okada discloses the claimed invention except for a gate mark is formed on the interconnection sheet. However, Kayahara et al. teaches a gate mark is formed on the interconnection sheet (6) (see paragraph [0064], lines 20-25). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to have a gate mark on the interconnection sheet for injecting plastic into the interconnection sheet during the injecting molding process. Regarding claim 11, Okada discloses the claimed invention except for another gate mark different from one formed on the interconnection sheet is formed on the rear stop. However, Kayahara et al. teaches another gate mark different from one formed on the interconnection sheet (6) is formed on the rear stop (4) (see paragraph [0064], lines 20-25). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to have a gate marks on the interconnection sheet and the rear stop for injecting plastic into the interconnection sheet and the rear stop during the injecting molding process. Regarding claim 20, Okada discloses the claimed invention except for a first gate mark is formed on the interconnection sheet, and a second gate mark is formed on the rear stop. However, Kayahara et al. teaches a first gate mark is formed on the interconnection sheet (6), and a second gate mark is formed on the rear stop (4) (see paragraph [0064], lines 20-25). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to have a gate marks on the interconnection sheet and the rear stop for injecting plastic into the interconnection sheet and the rear stop during the injecting molding process. Response to Arguments Applicant’s arguments, see pages 7-10, filed 07/16/2025, with respect to the rejection(s) of claims 1 and 12 under 35 USC § 102 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Okada (CN 101023823A). Okada broadly discloses a slider (34) that moves frontward to engage and rearward to disengage the fastener elements of said left and right rows of fastener elements (see Fig. 1 and annotated Figs. 2 and 4); an interconnection sheet that joins the left and right waterproof tapes in a rear end of the waterproof slide fastener, the interconnection sheet selectively formed on the lower surfaces of the left and right waterproof tapes without being formed on the upper surfaces of the left and right waterproof tapes (see annotated Figs. 2 and 4); and a rear stop arranged at a rear contiguous position of the left and right rows of fastener elements, the rear stop partially covering the interconnection sheet (see annotated Figs. 2 and 4), wherein the linear arrangement of securement holes of the row of securement holes in each of the left and right waterproof tapes is divided into a multiplicity of securement holes and one rearmost securement hole arranged at a rearmost position in said linear arrangement and rearward of the multiplicity of securement holes, respective ones of the securement holes of said multiplicity of securement holes filled by respective ones of the fastener elements, no securement hole being arranged rearward of the rearmost securement hole (see annotated Figs. 2 and 4; and Fig. 16), and wherein the interconnection sheet is arranged to expose the rearmost securement hole (9) in at least one of the left and right waterproof tapes, and the rear stop is arranged to fill said rearmost securement hole (9) in at least one of the left and right waterproof tapes (see annotated Figs. 2 and 4).
