Office Action

§103
DETAILED ACTION 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 . Response to Amendment The amendments to claims 1, 2, 17, and 18 in the response filed on 10/21/2025 are acknowledged. Claims 1-4 and 6-23 remain pending in the application Claims 4-5 are cancelled. Claims 1-4 and 6-23 are examined. Response to Arguments The applicant’s arguments have been considered but are moot in view of the new grounds of rejection necessitated by the applicant’s amendments to the claims. The applicant has modified claims 1 and 17 to require each of the plurality of curved portions having a different radius of curvature, limitations heretofore not presented for examination in this application. As such, the scope of the claims was substantially changed and new grounds for rejection are presented. 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(s) 1-3 and 6-16 and 19-21 and 23 is/are rejected under 35 U.S.C. 103 as being unpatentable over JP2009189636A to Yamane in view of JPH08238215A to Kawano and in view of JP2004249007A to Yamamoto et al. (hereinafter “Yamamoto”) and in view of JP2002095633A to Komi. Regarding claim 1, Yamane discloses an insertion device comprising: a tube (Fig. 3-treatment tool insertion channel 30; see [0025]) comprising an opening disposed on a surface of the tube (Fig. 4; see [0028]), the tube extending along a longitudinal axis (Fig. 3-treatment tool insertion channel 30); and a frame (see frame in examiner’s annotated Fig. 3) comprising: a first conduit (Fig. 3- through hole 6; see [0030]) comprising an insertion port (Fig. 3- through hole 6; see [0030]), an axis of the first conduit having a first angle relative to the longitudinal axis (Fig. 3- through hole 6; see [0030]), and a second conduit (Fig. 3-second passage 44; see [0029]-[0036]) comprising an end connected to the opening (Fig. 3-second passage 44; see [0029]-[0036]), the second conduit being in fluid communication with the first conduit (Fig. 3-second passage 44; see [0029]-[0036]), the end having a second angle relative to the longitudinal axis (Fig. 3-second passage 44; see [0029]-[0036]), the second angle being smaller than the first angle (Fig. 3-second passage 44; see [0029]-[0036]). PNG media_image1.png 672 942 media_image1.png Greyscale Yamane fails to expressly teach a tube comprising an opening disposed on a circumferential surface and the second conduit comprising a plurality of curved portions connected seamlessly to each other, each of the plurality of curved portions having a different radius of curvature. However, Kawano teaches of an insertion device (Kawano: Fig. 1) including a second conduit (Kawano: 52, Fig. 4, [0012]) comprising a plurality of curved portions connected seamlessly to each other (Kawano: 52, Fig. 4, [0012]).

PNG media_image1.png 672 942 media_image1.png Greyscale Yamane fails to teach wherein the second conduit comprising a plurality of curved portions; wherein each of the plurality of curved portions has a curvature radius greater than zero and each of the plurality of curved portions having a different radius of curvature. However, Komi teaches of an insertion portion (Komi: Fig. 2) wherein the second conduit comprising a plurality of curved portions; wherein each of the plurality of curved portions has a curvature radius greater than zero and each of the plurality of curved portions having a different radius of curvature (Komi: Fig. 2, [0017]). Therefore, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the device of Yamane, in view of Kawano and in view of Yamamoto to utilize a different radius of curvature, as taught by Komi. It would have been advantageous to make the combination for the purpose of guiding the treatment tool into the passage ([0017] of Komi). Regarding claim 18, Yamane, in view of Komi, teaches the insertion device according to claim 17. Yamane, in view of Komi, fails to expressly teach wherein the plurality of curved portions comprises: a first curved portion having a first curvature center, the first curved portion being closest to the first conduit, the first curvature center disposed on a first side relative to a center axis of the second conduit; and a second curved portion having a second curvature center, the second curved portion disposed in a direction towards the opening, the second curvature center on a second side relative a center axis of to the second conduit, the second side being opposite to the first side across the center axis of the second conduit However, Komi further teaches wherein the plurality of curved portions comprises: a first curved portion having a first curvature center, the first curved portion being closest to the first conduit, the first curvature center disposed on a first side relative to a center axis of the second conduit; and a second curved portion having a second curvature center, the second curved portion disposed in a direction towards the opening, the second curvature center on a second side relative a center axis of to the second conduit, the second side being opposite to the first side across the center axis of the second conduit (Komi: Fig. 2, [0017]). Therefore, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the device of Yamane, in view of Kawano and in view of Yamamoto to utilize the curved portions, as taught by Komi. It would have been advantageous to make the combination for the purpose of guiding the treatment tool into the passage ([0017] of Komi). Regarding claim 22, Yamane, in view of Kawano, teaches the insertion device according to claim 17. Yamane, in view of Komi, fails to expressly teach wherein the plurality of curved portions are connected seamlessly to each other in a center axis direction of the second conduit. However, Komi further teaches wherein the plurality of curved portions are connected seamlessly to each other in a center axis direction of the second conduit (Komi: Fig. 2, [0017]). Therefore, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the device of Yamane, in view of Komi, to utilize the curved portions, as taught by Komi.
