With respect to claim 16, Dobashi discloses a traction system comprising: a multi-ring traction device (10) comprising a first ring (e.g., 12) connected to a second ring (e.g., 14) such that an outer edge of the first ring is directly coupled to an outer edge of the second ring (see fig. 1 above), each ring having a core curve (see fig.1 above), the multi-ring traction device comprising synthetic resin (see para. 34 and note that the device is fabricated with nylon); and a sheath (e.g., 34); wherein the multi-ring traction device is bendable and deformable to fit within the sheath (note that this device is capable of performing this function), and the sheath is insertable within a channel of an endoscope (32, see fig. 11a).
As for claim 17, Dobashi further discloses the traction system according to claim 16, wherein: the multi-ring traction device further comprises a third ring (16) having a core curve (see fig. 1 above); and the first ring, the second ring, and the third ring are connected to one another in a row (see fig. 1 above).
As for claim 18, Dobashi further discloses the traction system according to claim 17, wherein the rings are connected in the diametrical direction of the core curves of the rings (see fig. 1 above).
As for claim 19, Dobashi further discloses the traction system according to claim 16, further comprising a clip (e.g., 30) connected to one of the rings of the multi-ring traction device (see fig. 2).
Claim Rejections - 35 USC § 103
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) 3, 4, 6, 7 and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Dobashi (US 20190133591), as applied to claims 1, 5 and 16 above, in view of Raju (US 20070250116).
As for claims 3, 6 and 20, Dobashi appears to illustrate the rings each having the same diameter (see fig. 1 above) but does not explicitly state wherein the rings each have the same diameter.
Raju, also drawn to multi-ring traction devices, teaches rings (e.g., 6, 8, 10) wherein the rings each have the same diameter (see para. 33) in order to provide consistently dimensioned anchoring points that allow the desired tissue traction and/or retraction (see para. 12-15).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify Dobashi wherein the rings each have the same diameter, as a matter of engineering design choice, in view of Raju, in order to provide consistently dimensioned anchoring points that allow the desired tissue traction and/or retraction.
As for claims 4 and 7, Dobashi is silent regarding the dimensions of the rings, specifically, wherein the core curve of each of the rings is 5 mm to 10 mm.
Ragu teaches that the dimensions of the ring are about 3 mm in diameter (see para. 33) in order to provide consistently dimensioned anchoring points that allow the desired tissue traction and/or retraction at the surgical site for a particular patient (see para. 12-15).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify Dobashi wherein the rings each have a core curve diameter of about 3mm, as a matter of engineering design choice, in view of Raju, in order to provide consistently dimensioned anchoring points that allow the desired tissue traction and/or retraction at the surgical site for a particular patient.
Dobashi, as modified by Ragu, does not appear to specifically teach wherein the core curve of each of the rings is 5 mm to 10 mm.
It would have been obvious to one having ordinary skill in the art at the time the invention was made to construct the ring of Dobashi, as modified by Ragu,, which was designed for approximation and retraction of tissues, wherein the core curve of each of the rings is 5 mm to 10 mm, as a matter of engineering design choice, in order to accommodate a particular surgical procedure for particular patient, since it has been held that where the general conditions of a claim are disclosed, in the prior art, discovering optimum or workable ranges involves only routine skill in the art (in re Aller, 105 USPQ 233).
Claim(s) 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Dobashi (US 20190133591), as applied to claim 5 above, in view of Kobayashi (US 20130053745).
As for claim 12, Dobashi does not teach wherein a diameter of a cross-section of each ring is 0.1 mm to 0.5 mm.
Kobayashi, also drawn to multi-ring traction devices, teaches rings (e.g. connecting member 23, see para. 111) wherein a diameter of a cross-section of each ring is 0.1 mm to 0.5 mm (see para. 113) in order to ensure that the loop has the desired amount of strength when the device is engaged to tissue (see para. 113).
It would have been obvious to one of ordinary skill before the effective filing date of the invention to modify Dobashi wherein a diameter of a cross-section of each ring is 0.1 mm to 0.5 mm, as a matter of engineering design choice, in view of Kobayashi, in order to ensure that the loop has the desired amount of strength when the device is engaged to tissue.
Claim(s) 9-11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Dobashi (US 20190133591), as applied to claim 5 above.
As for claims 9-11, wherein the rings are integrally molded together; wherein the rings are separately formed and then connected together and wherein the rings are ultrasonically welded together, it is noted that the device of Dobashi appears to be substantially identical to the device claimed, although produced by a different process, therefore the burden is upon the application to come forward with evidence establishing an unobvious difference between the two. In re Marosi, 218 USPQ 289 (Fed. Cir. 1983).
Response to Arguments
The USC 101 rejection made to claims 1-4 is withdrawn in view of the amendment entered on 6/18/2026.
The USC 112b rejection of claims 12 and 14 is withdrawn in view of the amendment entered on 6/18/2026.
Applicant’s arguments with respect to claim(s) 1-20 have been considered but are moot because the new ground of rejection does not rely on the newly presented reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. This reference is applied in response to the amendment to the claims entered on 6/18/2026.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
