DETAILED ACTION 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 . Response to Arguments Applicant’s arguments with respect to claim(s) 1-12 and 22-29 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. Response to Amendment Applicant’s Amendment filed on 03/16/2026 regarding claims 1-29 is fully considered. Of the above claims, claims 13-21 have been canceled; claims 1-2, 4-5, 8 and 11 have been amended; claims 22-29 have been newly added. 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. Claim(s) 1-8, 11 and 22-27 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Adams et al. (US 5,979,771). Regarding claim 1, Adams et al. teach a testing system (SIM contact position tester board 100; Figs 1A-1B), comprising: a tester card configured to be inserted into a slot of a card reader configured to read a chip of a chip card (the SIM contact position tester 100 as inserted into the radio telephone housing 104 via the slot 103; column 2, lines 26-34), wherein a length of the tester card is divided into a first portion and a second portion (portion with sets of traces A-D and portion with light emitting diodes 106; FIG. 2); wherein the first portion of the tester card includes an indicator configured to indicate a result of testing (the LEDs 106 are configured to be lit up as the traces of each set A-D slide over the respective contacts internal to the radio telephone upon insertion of the PWB 102; column 2, lines 45-56) and the second portion of the tester card includes an electrical contact (eight SIM card interface contacts c1-c8 are configured to match up with the traces of trace sets A-D mounted on the PWB 102; FIG. 3; column 2, lines 57-64); and wherein, responsive to the second portion of the tester card being inserted as fully as possible into the slot of the card reader, the indicator is configured to be activated if the electrical contact is operatively engaged with a chip reader of the card reader and remains inactive if the electrical contact is not operatively engaged with the chip reader of the card reader (the LEDs 106 are configured to be lit up as the traces of each set A-D slide over the respective contacts internal to the radio telephone upon insertion of the PWB 102; column 2, lines 45-56; this causes the corresponding LEDs of the LED bank 106 to light up; column 3, lines 8-13; column3, lines 41-50; LEDs 106 do not lit up if the traces A-D do not slide over the internal contacts). Regarding claim 2, Adams et al. teach wherein the tester card includes an electrical path between the indicator and the electrical contact (circuitry including a plurality of buffers embodied within integrated circuits 108a-108d couples the SIM card traces A-D and hence contacts c1-c8 with a plurality of light emitting diodes 106; column 2, lines 45-56); in a default state the electrical path is incomplete such that the indicator is not activated (when traces A-D are not in contact with contacts c1-c8; Figs 3-4); and with the second portion of the tester card inserted as fully as possible into the slot, the electrical path is configured to be complete between the indicator and the electrical contact (when traces A-D are in contact with contacts c1-c8; FIGs. 3-4). Regarding claim 3, Adams et al. teach wherein the indicator includes a light, the indicator being activated includes the light being illuminated, and the indicator not being activated includes the light not being illuminated (the LEDs 106 are configured to be lit up as the traces of each set A-D slide over the respective contacts internal to the radio telephone upon insertion of the PWB 102; column 2, lines 45-56). Regarding claim 4, Adams et al. teach wherein, with the second portion of the tester card inserted as fully as possible into the slot, the indicator not being activated is indicative of foreign matter being present in the slot (the LEDs 106 are configured to be lit up as the traces of each set A-D slide over the respective contacts internal to the radio telephone upon insertion of the PWB 102; column 2, lines 45-56; the LEDs 106 not being lit up could indicate foreign matter preventing the traces A-D from making contact with the contacts c1-c8). Regarding claim 5, Adams et al. teach wherein, with the second portion of the tester card inserted as fully as possible into the slot, the first portion of the tester card is located outside of the slot (when the SIM contact position tester board 100 is fully inserted, the portion of the SIM contact position tester board 100 with the LEDs 106 is located outside; FIG. 1B). Regarding claim 6, Adams et al. teach the card reader including the chip reader (the SIM card might record the subscriber telephone number, a personal identification number, as well as call charge information or a telephone number index; column 1, lines 12-20; the SIM being a chip).

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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 9-10, 12 and 28-29 is/are rejected under 35 U.S.C. 103 as being unpatentable over Adams et al. (US 5,979,771) in view of Denton et al. (US 2024/0280719 A1).
