Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 2-3 and 12-13 rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claims 2-3 and 12-13 recites the limitation "the cover" in line 1 respectively. There is insufficient antecedent basis for this limitation in the claim. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1 and 3 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hsu et al. (US 20160043511), hereinafter Hsu. PNG media_image1.png 460 537 media_image1.png Greyscale Regarding claim 1, Hsu discloses an electrical connector (electrical connector 100, Fig. 1), comprising: a housing (insulative housing 5, Fig. 2), the housing defining a receiving slot (mating cavity 101, Fig. 1) configured to at least partially receive a mating module (Par. 0016, an electrical connector 100 is preferably a plug to be mounted on a printed circuit board for a corresponding mating connector inserted) along a first direction; the housing comprising a first upper surface (see Fig. 3 above, first upper surface 5a) and at least one weight-reducing groove (see Fig. 3 above, weight reducing groove 5b) recessed downwardly from the first upper surface; a first conductive terminal (first conductive terminals, Fig. 3), the first conductive terminal being mounted to the housing (Fig. 2); the first conductive terminal comprising a first contact arm (part of first conductive terminal 31, see Fig. 4); the first contact arm comprising a first contact portion (first contacting portions 311, Fig. 4) protruding into the receiving slot; and a cover plate (metal shell 2, Fig. 1-2), the cover plate being fixed to the first upper surface and covering the at least one weight-reducing groove (see Fig. 1). Regarding claim 3, Hsu discloses the electrical connector according to claim 1, wherein the cover is configured to be sucked by a suction cup so as to grasp the electrical connector (see Fig. 1-2 for flat smooth surface of metal shell 2 capable of being sucked by a suction cup). 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) 1 and 4 are rejected under 35 U.S.C. 103 as being unpatentable over Xu et al. (US 20200412067), hereinafter Xu in view of Hsu (US 20160043511). PNG media_image2.png 603 769 media_image2.png Greyscale Regarding claim 1, Xu discloses an electrical connector, comprising: a housing (metal housing 60, Fig. 1), the housing defining a receiving slot (opening slot 643, Fig. 3) configured to at least partially receive a mating module along a first direction (Par. 0044, “the first conductive terminals 10 and the second terminals 20 described in the previous paragraphs are respectively and symmetrically disposed on the upper surface of the first carrier board 301 and the lower surface of the second carrier board 302 for mating with another connector”); a first conductive terminal (first conductive terminals 10, Fig. 1), the first conductive terminal being mounted to the housing (see Fig. 5); the first conductive terminal comprising a first contact arm (see Fig. 6 above, 10a); the first contact arm comprising a first contact portion protruding into the receiving slot (see Fig. 6 above, 10b). However, Xu fails to disclose wherein the housing comprises a first upper surface and at least one weight-reducing groove recessed downwardly from the first upper surface; and a cover plate, the cover plate being fixed to the first upper surface and covering the at least one weight-reducing groove. PNG media_image1.png 460 537 media_image1.png Greyscale Hsu teaches wherein the housing comprises a first upper surface (see Fig. 3 above, first upper surface 5a) and at least one weight-reducing groove (see Fig. 3 above, weight reducing groove 5b) recessed downwardly from the first upper surface; and a cover plate (metal shell 2, Fig. 1-2), the cover plate being fixed to the first upper surface and covering the at least one weight-reducing groove (see Fig. 1). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the teachings of Hsu to modify the invention of Xu to provide an electrical connector wherein the conductive housing comprises a first upper surface and a plurality of weight reducing grooves and a cover plate fixed to the upper surface and covering the weight reducing grooves. One would be motivated to make this modification in order to simplify manufacturing costs. Weight reducing grooves are well known in the field and a person of ordinary skill in the art would find it obvious to cut away material from an upper surface of the connector body. Regarding claim 4, Xu discloses the electrical connector according to claim 1, wherein the housing is a conductive housing; the conductive housing is a metal housing (metal housing 60, Fig. 1); or the conductive housing is a composite housing formed by electroplating a metal material on an insulating material. Claim(s) 2 is rejected under 35 U.S.C. 103 as being unpatentable over Xu and Hsu as applied to claim 1 above, and further in view of Ni et al. (US Patent 7,297,024), hereinafter Ni. Regarding claim 2, Xu discloses the electrical connector according to claim 1. However, Xu fails to disclose wherein the cover is a polyester film. Ni teaches wherein the cover (plastic cover 68, Fig. 2B) is a polyester film. Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the teachings of Ni to modify Hsu to provide a cover plate being made of a polyester film. Plastic covers are well known in the art and a person of ordinary skill would make this modification to reduce weight of the connector as well as provide a nonconductive part attached to the electrical connector. Claim(s) 11 and 13-14 are rejected under 35 U.S.C. 103 as being unpatentable over Xu (US 20200412067), in view of Hsu (US 20160043511). PNG media_image2.png 603 769 media_image2.png Greyscale Regarding claim 11, Xu discloses an electrical connector (connector 100, Fig. 1), comprising: a conductive housing (metal housing 60, Fig. 1), the conductive housing defining a receiving slot (opening slot 643, Fig. 3) configured to at least partially receive a mating module along a first direction (Par. 0044, “the first conductive terminals 10 and the second terminals 20 described in the previous paragraphs are respectively and symmetrically disposed on the upper surface of the first carrier board 301 and the lower surface of the second carrier board 302 for mating with another connector”); a first conductive terminal (first conductive terminals 10, Fig. 1), the first conductive terminal being mounted to but not in contact with the conductive housing (see Fig. 5); the first conductive terminal comprising a first contact arm (see Fig. 6 above, 10a); the first contact arm comprising a first contact portion (see Fig. 6 above, 10b) protruding into the receiving slot to mate with the mating module. However, Xu fails to disclose wherein the conductive housing comprises a first upper surface and a plurality of weight-reducing grooves recessed downwardly from the first upper surface; wherein the plurality of weight-reducing grooves do not extend through the conductive housing so that the plurality of weight-reducing grooves are not in communication with the receiving slot and a cover plate, the cover plate being fixed to the first upper surface and covering the plurality of weight-reducing grooves. PNG media_image1.png 460 537 media_image1.png Greyscale Hsu teaches wherein the conductive housing comprises a first upper surface (see Fig. 3 above, first upper surface 5a) and a plurality of weight-reducing grooves (see Fig. 3 above, weight reducing groove 5b) recessed downwardly from the first upper surface; wherein the plurality of weight-reducing grooves do not extend through the conductive housing so that the plurality of weight-reducing grooves are not in communication with the receiving slot and a cover plate (metal shell 2, Fig. 1-2), the cover plate being fixed to the first upper surface and covering the plurality of weight-reducing grooves (see Fig. 1). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the teachings of Hsu to modify the invention of Xu to provide an electrical connector wherein the conductive housing comprises a first upper surface and a plurality of weight reducing grooves and a cover plate fixed to the upper surface and covering the weight reducing grooves. One would be motivated to make this modification in order to simplify manufacturing costs. Weight reducing grooves are well known in the field and a person of ordinary skill in the art would find it obvious to cut away material from an upper surface of the connector body. Regarding claim 13, Xu discloses the electrical connector according to claim 11. However, Xu fails to disclose a cover plate. Hsu teaches a cover plate (see discussion in claim 11 above) wherein the cover is configured to be sucked by a suction cup so as to grasp the electrical connector (see Fig. 1-2 for flat smooth surface of metal shell 2 capable of being sucked by a suction cup). Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the teachings of Hsu to modify Xu to provide an electrical connector comprising a cover plate capable of being sucked by a suction cup. Regarding claim 14, Xu discloses the electrical connector according to claim 11, wherein the conductive housing is a metal housing (metal housing 60, Fig. 1); or the conductive housing is a composite housing formed by electroplating a metal material on an insulating material. Claim(s) 12 is rejected under 35 U.S.C. 103 as being unpatentable over Xu and Hsu as applied to claim 11 above, and further in view of Ni et al. (US Patent 7,297,024), hereinafter Ni. Regarding claim 12, Xu discloses the electrical connector according to claim 11. However, Xu fails to disclose wherein the cover is a polyester film. Ni teaches wherein the cover (plastic cover 68, Fig. 2B) is a polyester film. Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the teachings of Ni to modify Hsu to provide a cover plate being made of a polyester film. Plastic covers are well known in the art and a person of ordinary skill would make this modification to reduce weight of the connector as well as provide a nonconductive part attached to the electrical connector.
