Office Action

§102 §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 This office action is responsive to the amendment filed on 12/10/2025. As directed by the amendment: claim 1 has been amended and claims 15 and 22-24 have been cancelled. Thus, claims 1-14 and 16-21 are presently pending in this application. Election/Restrictions Applicant's election with traverse of in the reply filed on 12/10/2025 is acknowledged. The traversal is on the ground(s) that the technical features of the invention do make a contribution over the prior art in view of Martin. The applicant had amended claim 1 which was used for the basis of the restriction to further recite “the first distance and the second distance are not equal to each other”. This changes the scope of the shared technical features of the invention. This is not found persuasive because the applicant changed the basis on which the restriction was made, and Martin originally disclosed the shared technical features, hence the restriction is maintained. The requirement is still deemed proper and is therefore made FINAL. Claims 6-9, 15, and 21 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected species, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 12/10/2025. Claim Rejections - 35 USC § 102 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.

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. 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) 13-14 and 17-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Meade. Claim 13 Meade discloses: The needle driver device of claim 12, see 102 rejection above. Meade does not explicitly disclose: wherein the path along which distal end portion of the needle driver link is movable is a non-circular arc path. However, a variant embodiment (Figs. 39A-43) of Meade teaches in the same field of invention a needle driver device 356 (see Figs. 39A-43) with a needle driver link 302 (see Figs. 39A-43) with a distal end portion 308 (see Figs. 39A-43), a needle 220 (see Figs. 39A-43) with a circular arc needle track 332 (see Figs. 39A-43). The variant embodiment of Meade (Figs. 39A-43) further teaches: wherein the path 334 + 335 (see Figs. 40-43, [0142]) along which distal end portion 308 of the needle driver link 302 is movable is a non-circular arc path (see Figs. 40-43, [0143], it is a non-circular path, as 308 moves distally in a circular arc, and then disengages from the needle moves away from 334 into 335, and rotates back, which is a non-circular arc path as it does not come back on the same path). 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 Meade to incorporate the teachings of a variant embodiment (Figs. 39A-43) of Meade and teach a needle driver wherein the path along which distal end portion of the needle driver link is movable is a non-circular arc path. Motivation for such can be found in Meade as this assists in preventing an anti-rotate motion, or reverse motion of the needle during surgery (see [0147] and [0149]). Claim 14 Meade teaches: The needle driver device of claim 13, see 103 rejection above. Meade further discloses: further comprising a curved needle 220 (see Fig. 26, 220 is a curved needle) movable along the needle track 192 (see Figs 26-37). Claim 17 Meade discloses: A needle driver device 150 (see Figs. 24-38, [0119]) comprising: a curved needle track 192 (see Figs. 26 and 28, [0125]) defining a curved path the curved path of 192 (see Figs. 26 and 28, [0125]); a rotary drive member 174 + 172 (see Figs. 26-27B and 34-35, [0125]); and a needle driver link 202 (see Figs. 26-27B and 34-35, [0125]) comprising: a distal end portion 198 (see Figs. 26-27B, 29, and 33, [0130]) removably engageable (see [0125], the shoulder screw can be removed to disengage the needle from the pawl 198) with a curved needle 220 (see Figs. 26-38, [0121]) configured to be received in the curved needle track 192, a first portion (see annotated Fig. 34 and 35 below) coupled to the rotary drive member 174; and a longitudinal axis the longitudinal axis of 202 (see Figs. 34-35) extending between the distal end portion 198 and the first portion (see annotated Fig. 34 and 35 below), wherein the needle driver link 202 moves in response to rotation of the rotary drive member 174 + 172 to drive the curved needle 220 along the curved needle track 192 (see [0126]) and wherein, in response to rotation of the rotary drive member 174 + 172, the distal end portion 198 of the needle drive link 202 traverses an arcuate-shaped path (see [0126]). PNG media_image2.png 858 824 media_image2.png Greyscale Meade does not explicitly teach: that deviates in shape from the curved path defined by the curved needle track. However, a variant embodiment (Figs. 39A-43) of Meade teaches in the same field of invention a needle driver device 356 (see Figs. 39A-43) with a needle driver link 302 (see Figs. 39A-43) with a distal end portion 308 (see Figs. 39A-43) with an arcuate-shaped path 334 + 335 (see Figs. 39A-43), a needle 220 (see Figs. 39A-43) with a circular arc needle track 332 (see Figs. 39A-43) with a circular path circular path of 332. The variant embodiment of Meade (Figs. 39A-43) further teaches: wherein the arcuate-shaped path 334 + 335 (see Figs. 39A-43, [0143]) deviates in shape (see Figs. 40-43, [0143], it is a non-circular path, as 308 moves distally in a circular arc, and then disengages from the needle moves away from 334 into 335, and rotates back, which is a non-circular arc path as it does not come back on the same path) from the curved path the curved path of 332 defined by the curved needle track 332. 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 Meade to incorporate the teachings of a variant embodiment (Figs. 39A-43) of Meade and teach a needle driver with an arcuate-shaped path for the distal end portion of the needle drive link that deviates in shape from the curved path defined by the curved needle track. Motivation for such can be found in Meade as this assists in preventing an anti-rotate motion, or reverse motion of the needle during surgery (see [0147] and [0149]). Claim 18 Meade teaches: The needle driver device of claim 17, see 103 rejection above. Meade further teaches: wherein the rotary drive member 174 + 172 is a first rotary drive member 174 (see Figs. 26-27B and 34-35, [0125]), and wherein the needle driver link 202 comprises a second portion (see annotated Fig. 34 and 35 below claim 17) rotatably coupled to a second rotary drive member 172 (see Figs. 26-27B and 34-35, [0125]). Claim 19 Meade teaches: The needle driver device of claim 18, see 103 rejection above. Meade further teaches: wherein the first rotary drive member 174 and the second rotary drive member 172 are coupled (see Figs. 34-35, [0132], coupled via 175 and 202) to rotate in a same direction (see [0132], synchronized rotation). Claim 20 Meade teaches: The needle driver device of claim 19, see 103 rejection above. Meade further teaches: wherein the first rotary drive member 174 and the second rotary drive member 172 are rotationally coupled by an actuation member 175 (see Fig. 34, [0132]) actuatable to rotate the first rotary drive member 174 and the second rotary drive member 172 (see [0132], synchronized rotation).
