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 . 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 14 May 2026 has been entered. Claims 15-20 are withdrawn; claims 1-14 are pending. Response to Arguments Applicant’s arguments, see “Remarks”, filed 14 May 2026, with respect to the rejection(s) of claim(s) 1-14 under Purcell and Wallace 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 Therefore, the rejection has been withdrawn.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 Purcell and Wallace. 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, 4-5 and 14 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Purcell et al (U.S. 2019/0216601). Purcell discloses (Figures 3-6) an elongate element (suture 74); a needle (sharpened distal end 32) comprising a curve, the needle disposed at a distal end of the elongate element; and at least one radiopaque marker element (80) comprising a coil (par. 057) coupled to at least a portion of an outer surface of the elongate element. Regarding claim 2, Purcell discloses (Figures 3-6) the elongate element is a suture (74). Regarding claim 4, Purcell discloses (Figures 3-6) the at least one radiopaque marker element includes a helical coil (406). Regarding claim 5, Purcell discloses (Figure 3) the helical coil is wrapped around the elongate element. Regarding claim 14, Purcell discloses (par. 0056) the at least one radiopaque marker element includes a plurality of connected radiopaque marker elements (“The suture may additionally carry one or two or more radiopaque markers 82 spaced apart from the hub 57, and may extend proximally through the proximal connector and a central lumen in the rotational driver.”). 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. Claims 3 and 6-13 are rejected under 35 U.S.C. 103 as being unpatentable over Purcell et al (U.S. 2019/0216601) in view of Wallace et al (U.S. 7,695,484). Purcell discloses the claimed invention except for the at least one radiopaque marker includes portions having different radiopacities. Wallace, however, discloses (col. 6, lines 4-59) a helically coiled radiopaque device that varies its pitch from open to closed along its length in order to provide variable thickness and density. Wallace and Purcell both disclose systems for providing helically coiled radiopaque elements in an implanted device. Therefore, it would have been obvious to one of ordinary skill in the art at the time of the invention to modify Purcell’s needle system with Wallace’s varying winding along the length of the elongate element in order to provide variable shape and flexibility for stability in placement of the device. Regarding claim 6, Wallace discloses (col. 6, lines 4-59) the helical coil includes portions having different winding densities, and wherein the different winding densities have different radiopacities. Regarding claim 7, Wallace discloses (col. 6, lines 4-59) the helical coil includes a plurality of high-density winding portions that are spaced apart along at least a portion of the elongate element. Regarding claim 8, Wallace discloses (col. 6, lines 4-59) the plurality of high-density winding portions are unconnected. Regarding claim 9, Wallace discloses (col. 6, lines 4-59) the helical coil includes a plurality of high-density winding portions that are separated by low-density winding portions along at least a portion of the elongate element. Regarding claim 10, Wallace discloses (col. 6, lines 4-59) the plurality of high-density winding portions comprise different radiopacities. Regarding claim 11, Wallace discloses (col. 6, lines 4-59) the high-density winding portions and the low-density winding portion create a pattern of radiopacity. Regarding claim 12, Wallace discloses (col. 6, lines 4-59) the pattern of radiopacity repeats along the elongate element. Regarding claim 13, Wallace discloses (col. 6, lines 4-59) the at least one radiopaque marker element is configured for varying tactile and visual feedback via modifications of a coil density of the helical coil.
