Office Action

§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 status Claims 1-2 and 4-21 are pending; claims 1, 16 and 18 are independent. Claims 8-15 and 20 withdrawn from further consideration. Claim 3 has been cancelled. Response to Arguments Applicant's arguments filed 01/21/2026 have been fully considered but they are not persuasive. In response to applicant’s argument that the cited references do not appear to teach or suggest “wherein, in the second mode, at least one of the first trace line or the second trace line is configured to be grounded or electrically floating”, as recited in amended claims 1 and 16. However, the examiner respectfully disagrees, Lee clearly taught in fig. 29 and Paras 0299-0301, wherein a plurality of sub-ground lines SGL may extend in the second direction (Y-axis direction). The plurality of sub-ground lines SGL may be connected to the second ground line GRL2 in the sensor peripheral area TPA, but the present disclosure is not limited thereto. The plurality of sub-ground lines SGL may be electrically floating without being connected to the second ground line GRL2. The protection pattern PPE may be electrically floated or connected to the second ground line GRL2 to receive a ground voltage. In this case, because static electricity applied to the sensor electrode SE may be discharged to the protective pattern PPE, the sensor electrode SE may be protected from static electricity (Para 0344, Lee). 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) 1-2, 4-6, 16-17, 19 and 21 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kang (US 2014/0139447), in view of Smith (US 2021/0373711), both references provided by applicant’s IDS, and further in view of Lee (US 2021/0263606). Regarding claim 1, Kang teaches an electronic device (fig. 1, a touch screen panel) comprising: a display layer in which a display region, and a non-display region adjacent to the display region, are defined (fig. 1, a substrate 10 and Para 0046, wherein a substrate 10 having flexibility and divided into an active area and a non-active area positioned at the outside of (e.g., surrounding or around) the active area); and a sensor layer above the display layer for selectively operating in a first mode for sensing a touch, or in a second mode for sensing folding of the display layer and the sensor layer (fig. 1, and Para 0046, wherein sensing patterns 220 formed on the active area of a first surface of the substrate 10. In Para 0052, the touch screen panel according to this embodiment is implemented with a sensor sensing the presence of bending of the substrate 10, i.e., a bending sensor 240. In fig. 2A/B and Paras 0060-0065, folded or unfolded state of the flexible substrate 10 based on bending sensor 240), and comprising: first electrode groups arranged in a first direction (fig. 1, sensing cells 220a); second electrode groups arranged in a second direction crossing the first direction, crossing the first electrode groups (fig. 1, sensing cells 220b), an insulating layer disposed between the first and second trace lines and the first and second electrode patterns (fig. 4 and Para 0083, wherein an insulation layer (not shown) for securing stability is interposed between the first connecting lines 220a1 and the second connecting lines 220b1), in fig. 8 and Para 0122, an insulation layer 270 is interposed between the first connecting lines 220a1 and the second connecting lines 220b1), Kang does not expressly disclose the second electrode groups comprising a first electrode comprising first electrode patterns, and a second electrode comprising second electrode patterns in a same column as the first electrode patterns; first and second trace lines extending in parallel, and respectively connected to the first electrode patterns and the second electrode patterns in the same column; and wherein, in the second mode, at least one of the first electrode or the second electrode is configured to be grounded or electrically floated. However, Smith discloses disclose the second electrode groups comprising a first electrode comprising first electrode patterns, and a second electrode comprising second electrode patterns in a same column as the first electrode patterns; first and second trace lines extending in parallel, and respectively connected to the first electrode patterns and the second electrode patterns in the same column, see fig. 7B, and Paras 0074-0075; and wherein, in the second mode, at least one of the first electrode or the second electrode is configured to be grounded or electrically floated (figs 3A/B and Paras 0031-0032).
