Office Action

§102 §103
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 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 and 8 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Mizoguchi (JP 2012054915). Regarding claim 1, Mizoguchi discloses in Figures 1 and 13B, an antenna device comprising: an antenna base (88, Fig. 13B); an antenna case (9, Fig. 1) forming an accommodation space together with the antenna base; and a first antenna element (82, Fig. 13B) having a plate-like shape and accommodated in the accommodation space, wherein the first antenna element (82, Fig. 13B) is disposed along a direction intersecting a longitudinal direction of the antenna base, and wherein the first antenna element (82) includes a feeding point and is configured as a reflector (see page 12, par. 4) of another antenna accommodated in the accommodation space, wherein the antenna device further comprises a second antenna element (83, Fig. 13B), the second antenna element (83) having a plate-like shape and being disposed on one side in the longitudinal direction with respect to the first antenna element (82), wherein the second antenna element (83) is disposed along the longitudinal direction, and wherein a height (L1, Fig. 13B) of the first antenna element (82) is less than a height (L2, Fig. 13B) of the second antenna element (83). Regarding claim 8, as applied to claim 1, Mizoguchi discloses in Figure 13B, wherein the first antenna element (82) is a monopole antenna that includes a base end portion including the feeding point. 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. Claims 3, 15 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Mizoguchi (JP 2012054915). Regarding claims 3 and 15, as applied to claim 1, Mizoguchi discloses in Figure 13B, further comprising: a third antenna element (81) disposed on an other side in the longitudinal direction with respect to the first antenna element (82), Mizoguchi does not disclose wherein the height of the first antenna element is less than a height of the third antenna element. However, such differences are not patentable merit. It would have been obvious to one having ordinary skill in the art before the effective filing date of claimed invention to set or adjust the height of the third antenna being greater than the height of the first antenna to achieve a lower operating frequency than operating frequency of the first antenna, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only ordinary skill in the art. In re Aller, 105 USPQ 233. Regarding claim 19, as applied to claim 15, Mizoguchi discloses in Figure 13B, wherein the first antenna element (82) is a monopole antenna that includes a base end portion including the feeding point. Claims 4-5, 9-11, 16-17 and 20-21 are rejected under 35 U.S.C. 103 as being unpatentable over Mizoguchi (JP 2012054915) in view Terashita (US 2019/0280372). Regarding claims 4 and 16, Mizoguchi discloses every feature of claimed invention as expressly recited in claims 1 and 15, except for further comprising: two capacitive loading elements overlapping with the antenna base, wherein the first antenna element is disposed between regions of the antenna base overlapping with the two capacitive loading elements. Terashita discloses in Figure 2 and par. 0076, two capacitive loading elements (131, 132) overlapping with the antenna base (20), wherein the first antenna element (134) is disposed between regions of the antenna base (20) overlapping with the two capacitive loading elements (131, 132). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the first antenna element of Mizoguchi with the first antenna element having loading elements being capacitive loading elements as taught by Terashita to improve antenna gain. Therefore, to employ having the first antenna element having the capacitive loading elements as claimed invention would have been obvious to person skill in the art. Regarding claims 5 and 17, as applied to claims 4 and 16, Terashita discloses in Figure 2, wherein a height of the first antenna element (134) is less than a height of at least one of the two capacitive loading elements (131, 132). Regarding claims 9 and 20, as applied to claims 1 and 15, Terashita discloses in Figures 2 and 7-8, further comprising a capacitive loading element (131, 132), wherein the first antenna element (134) is located below the capacitive loading element (131, 132), and wherein in a top view the first antenna element (134) and the capacitive loading element (131, 132) at least partially overlap with each other. Regarding claims 10 and 21, as applied to claims 1 and 15, Terashita discloses in Figures 2 and 7-8, further comprising a capacitive loading element (131, 132), wherein the first antenna element (134) is located below the capacitive loading element (131, 132), and wherein in a side view a distance from the antenna base to an upper end of the first antenna element (134) is less than a distance from the antenna base to a lower end of the capacitive loading element (131, 132).s Regarding claim 11, as applied to claim 1, Mizoguchi (see Fig. 13) and Terashita (Figures 2, 7-8,) discloses in further comprising a second antenna element (81) and a third antenna element (82) disposed along the longitudinal direction, wherein the first antenna element (83) is located between the second antenna element (81) and the third antenna element (82) in the longitudinal direction. Mizoguchi does not disclose wherein in a side view a distance from the antenna base to an upper end of first antenna element is less than both a distance from the antenna base to an upper end of the second antenna element and a distance from the antenna base to an upper end of the third antenna element. However, such differences are not patentable merit. It would have been obvious to one having ordinary skill in the art before the effective filing date of claimed invention to set or select the distance of the first antenna element being shorter than the second and third antenna elements for achieving a desired operating frequency, and since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only ordinary skill in the art. In re Aller, 105 USPQ 233. Therefore, to employ having the height of the first antenna element as claimed invention would have been obvious to person skill in the art. Claims 6 and 12-14 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Mizoguchi (JP 2012054915) in view of Bunpei (WO 2020075744). Regarding claims 6 and 18, Mizoguchi discloses every feature of claimed invention as expressly recited in claims 1 and 15, except for the first antenna element including a portion to operate as a self-similar antenna or an antenna equivalent to the self-similar antenna. However, such differences are not patentable merit. A self-similar antenna is a well-known type antenna in the art. One of such examples is the teaching of Bunpei discloses in Figure 1, the antenna element (100) including a portion to operate as a self-similar antenna or an antenna equivalent to the self-similar antenna (100). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the antenna of Mizoguchi with the antenna being a self-similar antenna as taught by Bunpei to achieve desired radiation characteristic for the antenna device and since such modification would have involved a mere change in a type of an antenna generally recognized as being within the level of ordinary skill in the art. Regarding claim 12, as applied to claim 6, Mizoguchi discloses in Figure 12, wherein the portion of the first antenna element (83) includes a base end portion including the feeding point (86). Regarding claims 13-14, as applied to claim 8, Bunpei discloses in Figure 1, wherein a width of the first antenna element (100-2) in the direction intersecting the longitudinal direction increases from the base end portion toward an upper end of the first antenna element; a width of the first antenna element (100-2) in the direction intersecting the longitudinal direction on a distal side with respect to the base end portion is greater than a width of the first antenna element on a proximal side with respect to the base end portion. Response to Arguments Applicant’s arguments with respect to claims 1, 3-6 and 8-21 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
