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 Amendments to claims 1, 3, 4, 8, 12-14 of 8/5/2026 acknowledged and entered. Response to Arguments Applicant’s arguments, see p. 6, para. 2, filed 8/5/2026, with respect to claims 3, 8, 18 have been fully considered and are persuasive. The objection of 6/5/2026 has been withdrawn. Applicant’s arguments with respect to claim(s) 1, 12 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1, 2, 10, 12, 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hashimoto (US 20160135666 A1)in view of Okada (US 9649015 B2). Regarding claim 1, Hashimoto teaches A treatment tool comprising: a gripping device (fig. 2, element 9, [0032], extension tube member 9, extension tube member may be considered a gripping device in that the channel extension is taught to house a gripping device) having an elongated member (fig. 2, element 9, [0032], extension tube member 9) and a gripping portion (fig. 4, element 107/108, [0032], the first channel 107 or the second channel 108, first/second channels could be considered gripping portions in that they house a gripping device) connected to a distal end of the elongated member; an endoscope cap (fig. 3, element 1, [0025], an overtube 1) attached to an outer circumferential surface of a distal end portion of an endoscope; and a filament (fig. 4, element 5/6, [0032], first control wire 5 and a second control wire 6) coupling the gripping device with the endoscope cap (The filaments 5/6 is both fixed and connects to the gripping device, which is a part of the overtube, at the same point), wherein the filament is supported to be pivotable at a pair of fulcrums (fig. 4, element 3/4 , [0032], a first wire guide 3 and a second wire guide 4, control wires 5/6 bend as they exit wire guides 3/4, which construe fulcrum points) provided in the endoscope cap, and each of two end portions of the filament is fixed to the endoscope cap at a first position distally offset from a second position of each of the pair of fulcrums (fig. 4, element 5/6, [0032], The extension tube member 9 is connected to the treatment tool control wires 5 and 6) Hashimoto does not explicitly teach the filament being a continuous member. However, Okada teaches the filament being a continuous member (fig. 3, element 4, col. 5, ln. 60 – col. 6, ln. 11, The connecting member 4 is inserted into the through-hole 5b ). It would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the wires of Hashimoto to be a continuous wire as taught in Okada in order to pivotably couple the gripping device (Okada col. 5, ln. 60 – col. 6, ln. 11). Regarding claim 2, Hashimoto in view of Okada teaches The treatment tool according to claim 1, Further, Hashimoto teaches wherein each of the pair of fulcrums is a support hole ([0037], he pair of wire guides 3 and 4 may be formed of a metallic coil sheath, a resinous tube, a plurality of metallic or resinous rings separated from each other, or the like, the openings of the tubes penetrate the cap normal to a radial axis, hence a radial direction) that penetrates the endoscope cap in a radial direction. Regarding claim 10, Hashimoto in view of Okada teaches The treatment tool according to claim 1, Further, Hashimoto teaches wherein the filament is one of a thread or a wire ([0032], a first control wire 5 and a second control wire 6). Regarding claim 12, Hashimoto teaches An endoscope treatment tool comprising: a gripping device (fig. 2, element 9, [0032], extension tube member 9, extension tube member may be considered a gripping device in that the channel extension is taught to house a gripping device) an elongated member (fig. 2, element 9, [0032], extension tube member 9) and a gripping portion (fig. 4, element 107/108, [0032], the first channel 107 or the second channel 108, first/second channels could be considered gripping portions in that they house a gripping device) connected to a distal end of the elongated member; an endoscope cap (fig. 3, element 1, [0025], an overtube 1) attached to an outer circumferential surface of a distal end portion of an endoscope; and a filament (fig. 4, element 5/6, [0032], first control wire 5 and a second control wire 6) coupling the gripping device with the endoscope cap (The filaments 5/6 is both fixed and connects to the gripping device, which is a part of the overtube, at the same point), wherein the filament is supported to be pivotable at a pair of fulcrums (fig. 4, element 3/4 , [0032], a first wire guide 3 and a second wire guide 4, control wires 5/6 bend as they exit wire guides 3/4, which construe fulcrum points) provided in the endoscope cap, each of the pair of fulcrums is a support hole (fig. 7, element 12e, p. 7, para. 7, insertion holes 12e/f) that penetrates the endoscope cap in a radial direction, and each of two end portions of the filament is fixed to the endoscope cap at a first position distally offset from a second position of each of the pair of fulcrums (fig. 4, element 5/6, [0032], The extension tube member 9 is connected to the treatment tool control wires 5 and 6). Hashimoto does not explicitly teach the filament being a continuous member. However, Okada teaches the filament being a continuous member (fig. 3, element 4, col. 5, ln. 60 – col. 6, ln. 11, The connecting member 4 is inserted into the through-hole 5b ). It would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the wires of Hashimoto to be a continuous wire as taught in Okada in order to pivotably couple the gripping device (Okada col. 5, ln. 60 – col. 6, ln. 11). Regarding claim 19, Hashimoto in view of Okada teaches The treatment tool according to claim 12, Further, Hashimoto teaches wherein the filament is one of a thread or a wire ([0032], a first control wire 5 and a second control wire 6).
