Kataoka fail to disclose wherein the third winding part has an inner peripheral end being opened. However, Kato et al. does disclose wherein the third winding part has an inner peripheral end being opened (Coil antenna pattern 35b for IC card comprises multiple turns which can be taken as a first, second, and third winding part wherein the third winding part comprises an inner peripheral end, now labeled E2, that is open; Paragraph 35-41 and 69-71 as well as figure 2 and 17 of Kato et al.). Therefore, it would have been obvious before the effective filling date of the claimed invention to a person having ordinary skill in the art modify the antenna as taught by Kataoka to have wherein the third winding part has an inner peripheral end being opened as taught by Kato et al. since opens end offer better radiation efficiency and impedance control. Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over Kataoka (JP 2016162369 A) in view of Kato et al. (US 8602310 B2) and Orihara et al. (US 9496598 B2). Regarding Claim 5, Kataoka and Kato et al. fail to explicitly disclose wherein a pattern width of each of the first and third winding parts is smaller than a pattern width of the first partial winding part of the second winding part. However, Orihara et al. does disclose wherein a pattern width of each of the first and third winding parts is smaller than a pattern width of the first partial winding part of the second winding part (Coil antenna structure comprises a first, second , and third portion 5a, 5b, and 20 wherein the pattern width of a first partial winding of the second part is larger than the pattern width of the first and third parts 5a and 20; Paragraph 43-60 and figure 6 of Orihara et al.). Therefore, it would have been obvious before the effective filling date of the claimed invention to a person having ordinary skill in the art modify the antenna as taught by Kataoka and Kato et al. to have a pattern width of each of the first and third winding parts is smaller than a pattern width of the first partial winding part of the second winding part as taught by Orihara et al. since the spacing between the turns would affect the bandwidth and radiation efficiency. PNG media_image4.png 584 416 media_image4.png Greyscale Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over Kataoka (JP 2016162369 A) in view of Kato et al. (US 8602310 B2) and Finn et al. (US 20190197385 A1). Regarding Claim 6, Kataoka and Kato et al. fail to explicitly disclose wherein each of the first winding part, the first partial winding part of the second winding part, and the third winding part is constituted of a mesh-like conductor pattern. However, Finn et al. does disclose wherein each of the first winding part, the first partial winding part of the second winding part, and the third winding part is constituted of a mesh-like conductor pattern (Coil antenna comprises a first winding part CA, a second winding part EA-1 with a protruding portion CC serving as a first partial winding part, and a third winding part EA-2 wherein said structure may comprise a conductor mesh structure inserted into the material making the coils; Paragraph 223-227 and 461-467 as well as figure 4I of Finn et al.). Therefore, it would have been obvious before the effective filling date of the claimed invention to a person having ordinary skill in the art modify the antenna as taught by Kataoka and Kato et al. to have wherein each of the first winding part, the first partial winding part of the second winding part, and the third winding part is constituted of a mesh-like conductor pattern as taught by Finn et al. to alter the performance of the antenna structure (Paragraph 461-467 of Finn et al.). PNG media_image5.png 438 579 media_image5.png Greyscale Allowable Subject Matter Claim 4, 7, and 8-11 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Regarding claim 4, patentability exists, at least in part, with the claimed features of a “wherein a pattern width of the first partial winding part of the second winding part is larger than a pattern width of the second partial winding part of the second winding part” as recited in claim 4, claimed features “wherein the second partial winding part of the second winding part is constituted of a solid pattern.” as recited in claim 7, and claimed features “a second coil pattern having a fourth winding part, a fifth winding part, and a sixth winding part, wherein the fourth winding part is wound in a plurality of turns and has an outer peripheral end being opened and an inner peripheral end connected to an outer peripheral end of the fifth winding part, wherein the fifth winding part is wound in a plurality of turns and has an inner peripheral end connected to an outer peripheral end of the sixth winding part, wherein the sixth winding part is wound in a plurality of turns and has an inner peripheral end being opened, wherein each turn of the fifth winding part has a third partial winding part wound concentrically with the sixth winding part and a fourth partial winding part protruding radially outward from the third partial winding part and wound about a center axis positioned between the third partial winding part and the fourth winding part, and wherein the first and second coil patterns overlap each other such that center axes of the first and fourth winding parts are misaligned and that center axes of the third and sixth winding parts are misaligned” as recited in claim 8.
