Accordingly, the information disclosure statement(s) is/are being considered by the examiner. 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 13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Su et al. (WO 2023174274 A1), hereinafter known as Su. Regarding claim 1, Su discloses (Figs. 1-22) a circularly polarized antenna (300), comprising a first arc-shaped radiator (314,321) and a second arc-shaped radiator (313, 322), wherein the first arc-shaped radiator and the second arc-shaped radiator are arranged at an interval (gaps 331, 332, see Fig. 22), the first arc-shaped radiator and the second arc- shaped radiator are located on a same circumference (see Figs. 21-22), one of the first arc-shaped radiator and the second arc-shaped radiator is provided with a first grounding point (312), another of the first arc-shaped radiator and the second arc-shaped radiator is provided with a feeding point (301), and the first arc-shaped radiator and the second arc-shaped radiator are configured to receive a first circularly-polarized signal (p. 5, para. 2). Regarding claim 13, Su discloses (Figs. 1-22) a wearable electronic device (100, see Fig. 1), comprising a housing (141), a position determination element (GPS technology disclosed, para. bridging 9-10) and a circularly polarized antenna (300), the circularly polarized antenna comprising a first arc-shaped radiator (314,321) and a second arc-shaped radiator (313, 322), wherein the first arc-shaped radiator and the second arc-shaped radiator are arranged at an interval (gaps 331, 332, see Fig. 22), the first arc-shaped radiator and the second arc- shaped radiator are located on a same circumference (see Figs. 21-22), one of the first arc-shaped radiator and the second arc-shaped radiator is provided with a first grounding point (312), another of the first arc-shaped radiator and the second arc-shaped radiator is provided with a feeding point (301), and the first arc-shaped radiator and the second arc-shaped radiator are configured to receive a first circularly-polarized signal (p. 5, para. 2), the housing comprising a bottom wall and a side wall connected to the bottom wall (see Fig. 1), wherein the circularly polarized antenna is provided on the side wall (see Fig. 5), and the position determination element is coupled with the circularly polarized antenna (GPS would have to be connected to a receiving antenna, para. bridging 9-10); and the circularly polarized antenna is configured to receive the first circularly- polarized signal and transmit the first circularly-polarized signal to the position determination element (para. bridging 9-10), and the position determination element is configured to determine a current geographical location according to the first circularly-polarized signal (describing basic GPS function, para. bridging 9-10). Allowable Subject Matter Claims 2-12 and 14-20 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. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Sung et al. (U.S. Patent Application No. 20210344106) teaches a wearable device.
