Office Action

§102
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 . 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, 6-8, 10, 11, and 15-17 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Guo et al. (2022/0270782). Guo et al. discloses a core wire set (Fig. 3) comprising a first core wire having a first conductive core (111) and a first insulation layer (112) individually covering the first conductive core; a second core wire having a second conductive core (111) and a second insulation layer (112) individually covering the second conductive core, and arranged parallel ([0013]) to the first core wire; a first covering layer (120) covering the first core wire and the second core wire; a second covering layer (130) covering the first covering layer, wherein a wire placement space is formed between the first covering layer and the second covering layer, and a bare metal wire (150) arranged in the wire placement space; wherein a gap is formed between the first covering layer and the first insulation layer and the second insulation layer (Fig. 3) (re-claims 1 and 10). Guo et al. also discloses that from the cross-section of the core wire set, the center of the first core wire, the center of the second core wire, and the center of the bare metal are arranged in a triangular shape (Fig. 3) (re-claims 2 and 11); a first side of the second covering layer (130) toward the bare metal wire is conducting ([0016], second metal shielding layer 130 may include a conductive layer partially bonded to an outer circumferential surface of the first metal shielding layer…the conductive layer…may be an aluminum/polypropylene strip) (re-claims 6 and 15); the first side of the second covering layer (130) toward the bare metal wire is a heat conductor (copper or aluminum) (re-claims 7 and 16); the second side of the second covering layer opposite to the bare metal wire is insulated (polypropylene, [0016]) (re-claim 8); a transmission cable comprising the core wire set and an outer insulation layer (140) covering the core wire set (re-claim 10); and the first side of the second covering layer opposite to the bare metal wire is insulated (polypropylene) (re-claim 17). Claims 1-5, 10-14, and 17 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kobayashi (2018/0075948). Kobayashi discloses a core wire set (Fig. 3) comprising a first core wire having a first conductive core (21) and a first insulation layer (22) individually covering the first conductive core; a second core wire having a second conductive core (21) and a second insulation layer (22) individually covering the second conductive core, and arranged parallel (abstract) to the first core wire; a first covering layer (4) covering the first core wire and the second core wire; a second covering layer (6a) covering the first covering layer, wherein a wire placement space is formed between the first covering layer and the second covering layer, and a bare metal wire (5) arranged in the wire placement space; wherein a gap is formed between the first covering layer and the first insulation layer and the second insulation layer (Fig. 3) (re-claims 1 and 10). Kobayashi also discloses that from the cross-section of the core wire set, the center of the first core wire, the center of the second core wire, and the center of the bare metal are arranged in a triangular shape (Fig. 3) (re-claims 2 and 11); the first side of the first covering layer faces the first core wire and the second core wire is insulated ([0045], PET) (re-claims 3 and 12); the second side (4a) of the first covering layer opposite to the first core wire and the second core wire is conducting (re-claims 4 and 13); the second side of the first covering layer opposite to the first core wire and the second core wire is heat conducting (copper or aluminum) (re-claims 5 and 14); a transmission cable comprising the core wire set and an outer insulation layer (6b) covering the core wire set (re-claim 10); and the first side of the second covering layer opposite to the bare metal wire is insulated (PET or PVC) (re-claim 17). Response to Arguments Applicant’s arguments with respect to claims 1 and 10 have been considered but are moot in view of new ground of rejection.
