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 . 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 December 2, 2025 has been entered. Response to Amendment The amendment filed December 2, 2025 has been entered. The Applicant amended claims 1, 8, and 20-21, and added claim 22. Claims 1-4 and 6-22 remain pending in the application. Applicant’s amendments to the Claims have overcome each and every objection previously set forth in the Final Office Action mailed October 10, 2025. The examiner withdraws the Specification and Claims objections in light of the amendments to the Claims. Applicant’s arguments with respect to claims 1-4 and 6-21 have been considered but are moot because the new ground of rejection does not rely on the combination of references applied in the prior rejection.

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 4, 6, and 9-12 are rejected under 35 U.S.C. 103 as being unpatentable over Miraftab in view of Leung et al. (US PGPUB 2020/0388918 A1), hereinafter known as Leung. Regarding claim 4, Miraftab further teaches (Fig. 5, 7) wherein: the slot (712) is a continuous slot (712), the multi-band antenna further comprises a first jumper member (508, 708), a shape formed by the slot (712) has a bottom (middle end of 712) and an open end (left end 712), and the first jumper member (508, 708) is disposed between the bottom (middle end of 712) and the open end (left end 712); and the strip conductor is located between the first jumper member and the microstrip line, or the microstrip line (750) is located between the first jumper member (508, 708) and the strip conductor (conductor between 712), two ends of the first jumper member (508, 708) are respectively located on two sides that are of the slot (712) and that are away from the strip conductor (conductor between 712), but does not specifically teach and the two ends of the first jumper member are separately connected to the reflection plate. However, Leung teaches (Fig. 2) two ends of the first jumper member (118) are separately connected to the reflection plate (110). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the multi-band antenna of Miraftab with Leung to include “two ends of the first jumper member are separately connected to the reflection plate,” as taught by Leung, for the purpose of impedance matching (see also [0057]). Regarding claim 6, Miraftab further teaches (Fig. 5, 7) wherein: the first jumper member (508, 708), the reflection plate (700), and the microstrip line (750) are separately located on different conductor layers of a printed circuit board (Abstract); but does not specifically teach and the first jumper member is connected to the reflection plate through a via provided on the printed circuit board. However, Leung teaches (Fig. 2) the first jumper member (118) is connected to the reflection plate through a via ([0059]). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the multi-band antenna of Miraftab with Leung to include “the first jumper member is connected to the reflection plate through a via,” as taught by Leung, for the purpose of impedance matching (see also [0057]). Regarding claim 9, Miraftab further teaches (Fig. 5, 7) wherein the multi-band antenna further comprises a second jumper member (508, 708), but does not specifically teach and two ends of the second jumper member are respectively connected to the first conductor part and the second conductor part. However, Leung teaches (Fig. 2) two ends of the second jumper member (118) are respectively connected to the first conductor part (left 112) and the second conductor part (right 112). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the multi-band antenna of Miraftab with Leung to include “two ends of the second jumper member are respectively connected to the first conductor part and the second conductor part,” as taught by Leung, for the purpose of impedance matching (see also [0057]). Regarding claim 10, Miraftab further teaches (Fig. 5, 7) wherein: the reflection plate (700) and the microstrip line (750) are located on different conductor layers of a printed circuit board (Abstract), and the second jumper member (508, 708) and the microstrip line (750) are located on a same conductor layer of the printed circuit board (Abstract); but does not specifically teach and that the two ends of the second jumper member are respectively connected to the first conductor part and the second conductor part comprises: the two ends of the second jumper member are respectively connected to the first conductor part and the second conductor part through a via provided on the printed circuit board. However, Leung teaches (Fig. 2) two ends of the second jumper member (118) are respectively connected to the first conductor part (left 112) and the second conductor part (right 112) comprises: the two ends of the second jumper member (118) are respectively connected to the first conductor part (left 112) and the second conductor part (right 112) through a via ([0059]). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the multi-band antenna of Miraftab with Leung to include “two ends of the second jumper member are respectively connected to the first conductor part and the second conductor part comprises: the two ends of the second jumper member are respectively connected to the first conductor part and the second conductor part through a via,” as taught by Leung, for the purpose of impedance matching (see also [0057]). Regarding claim 11, Miraftab does not specifically teach wherein two second jumper members are separately disposed on two sides of the microstrip line. However, Leung teaches (Fig. 2) two second jumper members (118) are separately disposed on two sides of the microstrip line (116). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the multi-band antenna of Miraftab with Leung to include “two second jumper members are separately disposed on two sides of the microstrip line,” as taught by Leung, for the purpose of impedance matching (see also [0057]). Regarding claim 12, Miraftab further teaches (Fig. 1, 5, and 7) wherein the printed circuit board comprises a dielectric substrate (102, 106) disposed between the reflection plate (100, 500, 700) and the microstrip line (750), and a spacing between the second jumper member (508, 708) and the microstrip line is a spacing that is a first value multiplying a thickness of the dielectric substrate (102, 106), wherein the first value is in a range from 0.1 to 10. Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Miraftab in view of Adachi et al. (US PGPUB 2004/0004571 A1), hereinafter known as Adachi. Regarding claim 8, Miraftab further teaches (Fig. 7) the second slot part is a U-shaped slot (712), but does not specifically teach wherein the first slot part is a ring-shaped slot, and an opening of the U-shaped slot faces a side that is away from the ring-shaped slot. However, Adachi teaches (Fig. 14A) wherein the first slot part (slot between 102, 103) is a ring-shaped slot (slot between 102, 103), and an opening of the U-shaped slot (501) faces a side that is away from the ring-shaped slot (slot between 102, 103). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the multi-band antenna of Miraftab with Adachi to include “wherein the first slot part is a ring-shaped slot, and an opening of the U-shaped slot faces a side that is away from the ring-shaped slot,” as taught by Adachi, for the purpose of ease of manufacturing (see also [0085]). Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Miraftab in view of Esselle et al. (WO 2005062422 A1), hereinafter known as Esselle. Regarding claim 16, Miraftab does not specifically teach wherein in the direction perpendicular to the cabling of the strip conductor, the width of the strip conductor is in a range from 0.1 mm to 10 mm. However, Esselle teaches (Fig. 1-2) wherein in the direction perpendicular to the cabling of the strip conductor (220), the width of the strip conductor is in a range from 0.1 mm to 10 mm (Wf). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to modify the multi-band antenna of Miraftab with Esselle to include “wherein in the direction perpendicular to the cabling of the strip conductor, the width of the strip conductor is in a range from 0.1 mm to 10 mm,” as taught by Esselle, for the purpose of achieving desired impedance matching (see also page 27). Such modification would have involved a mere change in the size of a component. A change in size is generally recognized as being within the level of ordinary skill in the art.
