Information Disclosure Statement The information disclosure statement (IDS) submitted on 1/29/2026 has been considered by the examiner. Response to Arguments Applicant’s arguments with respect to claims 1 and 12 and 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. 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 1, 2, 4-6 and 12-14 are rejected under 35 U.S.C. 103 as being unpatentable over Ponce de Leon et al. (US Patent Publication Number 2008/0238780 A1) in view of Blum (US Patent Publication Number 2012/0127420 A1). Ponce de Leon, teaches as claimed in claim 1, an antenna system (Fig 1 and 6) comprising a driven antenna element (44), a printed circuit board that carries on-board electronics communicatively coupled to the driven antenna element to communicate wireless signals via the driven antenna element (¶0019), the PCB defining a PCB ground plane (58)) for co- operation with the driven antenna element (44) in signal communication (¶0019) and a PCB extender (18) comprising a conductor electrically connected to the PCB ground plane (28) and projecting from the PCB for co-operation with the driven antenna element (44) in signal communication, Ponce de Leon fails to teach the rigid structural core such that the rigid structural core is, in cross-section, encased in the plastic synthetic material. In a related art, Blum teaches a rigid structural core (1601) of a respective body part of an electronics-enabled device (Fig. 16), the rigid structural core (1601) being of an electrically conductive metal material (¶0207 “core element 1601, which may in some embodiments comprise a conductive material and may be coupled to or disposed within the temple 1602 so as to provide a portion of a conductive path”) , and wherein each body part having a rigid structural core (1601) provided by a comprises synthetic material (1602, ¶0130 “the frame element comprises a plastic material)” supported by the rigid structural core (1601) such that the rigid structural core is, in cross-section, encased in the plastic synthetic material1 (1602, ¶0130 “the frame element comprises a plastic material), the rigid structural core (1601) being a rigid elongate element configured to define a primary skeletal structure of the respective body part (See Fig. 16), providing structural rigidity to the respective body part of the device (Fig. 16), and being configured to serve as driven antenna element.
