Election/Restrictions
Applicant’s election without traverse of species I and claims 1-4, 9-11, 13-17, 23, 25, 44-45 and 47-48 in the reply filed on February 16, 2026 is acknowledged.
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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 1-4, 9-11, 13-17, 23, 25, 44-45, and 47-48 are rejected under 35 U.S.C. 103 as being unpatentable over Bok et al., US 2017/0213873 A1 (hereinafter “Bok”) in view of Liu et al., US 2024/0258327 A1 (hereinafter “Liu”).
Regarding claim 1, Bok discloses a transparent display apparatus (FIGS. 1-6 and [0066]-[0071] further at Abstract describing transparent region therein and [0103]-[0112]), comprising:
a substrate (FIG. 4, [0109]-[0112], substrate 110) including a transmissive area (FIGS. 3-4, [0101]-[0112] transparent region 30) and a non-transmissive area (FIGS. 3-4, [0101]-[0112] opaque region 35), the non-transmissive area including a light emission area (FIGS. 3-4, [0101]-[0112], and sub-pixel regions 15, 20, 25) in which a light emitting element is disposed (FIGS. 3-4 [0109]-[0110] and [0127]-[0131] with OLED structure with a light emitting layer 330 formed within sub-pixel regions 15, 20, 25);
a touch sensor (FIG. 4, [0106]-[0111] and touch sensor electrode 360 and wiring 260 in region 30) disposed in the transmissive area on the substrate (FIG. 4, [0106]-[0111] touch sensor electrode 360 and wiring 260 in region 30); and
at least one undercut line (FIGS. 3-4 [0109]-[0110] and [0129]-[0132] pixel defining layer 310 being disposed adjacent to the sensor 360) disposed to be adjacent to the touch sensor (FIGS. 3-4 [0109]-[0110] and [0129]-[0132] pixel defining layer 310 being disposed adjacent to the sensor 360).
However, although Bok generally suggests signal lines [0104], Bok does not explicitly disclose a plurality of first signal lines disposed in the non-transmissive area on the substrate and extended in a first direction;
at least one second signal line disposed in the non-transmissive area on the substrate and extended in a second direction crossing the first direction.
In the same field of endeavor, Liu discloses a transparent display (Abstract, generally) with a plurality of first signal lines (FIGS. 8-12 [0149]-[0158] first traces 11 comprising 111 and 112 are formed) disposed in the non-transmissive area (FIGS. 8-12 [0149]-[0158], first traces 11 comprising 111 and 112 are formed in non-transmissive region A1) on the substrate (Liu FIG. 5, 100) and extended in a first direction (FIGS. 8-12 [0149]-[0158], first traces 11 comprising 111 and 112 are formed in non-transmissive region A1 extending in the X direction as illustrated therein);
at least one second signal line (FIGS. 8-14 [0149]-[0158] second traces 12 comprising third signal lines 121) disposed in the non-transmissive area (FIGS. 8-12 [0149]-[0158], second traces 12 are formed in non-transmissive region A1) on the substrate (Liu FIG. 5, 100) and extended in a second direction crossing the first direction (FIGS. 8-14 [0149]-[0158] and [0161]-[0164], second traces 12 are formed in non-transmissive region A1 and extend in the Y direction as illustrated therein).
Before the effective filing date, it would have been obvious to a person of ordinary skill in the art to modify the transparent display of Bok to incorporate the two sets of crossing signal lines as disclosed by Liu because the references are within the same field of endeavor, namely, transparent displays with transmissive and non-transmissive areas. The motivation to combine these references would have been to maximize the area of the transmissive region surrounded by the non-transmissive region thereby reducing diffraction and improving display quality (see Liu at least at [0159]). Therefore, a person of ordinary skill in the art would have been motivated to combine the prior art to achieve the claimed invention and there would have been a reasonable expectation of success.
Regarding claim 2, Bok in view of Liu discloses the transparent display apparatus of claim 1 (see above), wherein the at least one undercut line is extended to be adjacent to the touch sensor in the first direction or the second direction (Bok, (FIGS. 3-4 [0109]-[0110] and [0129]-[0132] pixel defining layer 310 being disposed adjacent to the sensor 360)
Regarding claim 3, Bok in view of Liu discloses the transparent display apparatus of claim 1 (see above), wherein the at least one undercut line is disposed to be adjacent to the touch sensor in the transmissive area (Bok, FIGS. 3-4 [0109]-[0110] and [0129]-[0132] pixel defining layer 310 being disposed adjacent to the sensor 360 and extending at least partially into the transparent region 30 at [0129]).
Regarding claim 4, Bok in view of Liu discloses the transparent display apparatus of claim 3 (see above), wherein the at least one undercut line is extended in the first direction to cross the transmissive area (Bok, FIGS. 3-4 [0109]-[0110] and [0129]-[0132] pixel defining layer 310 being disposed adjacent to the sensor 360 and extending at least partially into the transparent region 30 at [0129], may be disposed in the opaque region 35 and transparent region 30).

Regarding claim 14, Bok in view of Liu discloses the transparent display apparatus of claim 1 (see above), wherein the at least one undercut line is provided to separate or disconnect an organic light emitting layer constituting the light emitting element (Bok, FIGS. 3-4 [0109]-[0110] and [0129]-[0132] pixel defining layer 310 being disposed adjacent to pixels within the opaque region including the light emitting layer 330).
