wherein a portion of the first space is defined by and between the inner surface of the bending part and at least a portion of the first edge of the flexible display (see annotated fig. 8a above), the portion of the first edge extending from a front surface (see annotated fig. 8a below) of the display panel to the rear surface (see annotated fig. 8a above) of the flexible display, and the portion of the first edge comprising the edge of the polymer layer (401 in annotated fig. 8A teaches this limitation).
Moon does not explicitly teach:
a first filling member in the first space within the electronic device, such as to surround at least a part of the first edge together with the bending part,
wherein the first filling member is not within the second space between the window layer and the display panel,
wherein the first filling member covers at least a portion of the inner surface and at least a portion of the outer surface of the bending part,
wherein, at the first edge an edge of the polymer layer that faces in the first direction extends further in the first direction than an edge of the display panel that faces in the first direction.
However, Zhu teaches:
a first filling member (700, comprised of PU foam, CR foam, XPE foam, and the like ¶[0055])) and 600, fig. 3), in a first space (space occupied by 700 and 600) within an electronic device (300), such as to surround at least a part of a first edge (as disclosed in fig. 3) together with a bending part (320, fig. 3),
wherein the first filling member is not within a second space (space occupied by 500, fig. 3) between a window layer (400) and a display panel (200 and 300, fig. 3).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include a first filling member in a first space within the electronic device, such as to surround at least a part of the first edge together with the bending part, and not within a second space between the window layer and the display panel, in order to provide a more stable support effect on an internal structure of the bending part, and therefore, the bending part may not be easily damaged due to deformation (¶[0055]).
Moon in view of Shu does not explicitly disclose:
wherein the first filling member covers at least a portion of the inner surface and at least a portion of the outer surface of the bending part,
wherein, at the first edge an edge of the polymer layer that faces in the first direction extends further in the first direction than an edge of the display panel that faces in the first direction.
However, Burke teaches:

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to Moon’s electronic device as modified by Zhu, with Burke’s teaching, so that the first filling member covers at least a portion of the inner surface and at least a portion of the outer surface of the bending part, in order to reinforce or bolster the bending part of the display panel, against external forces or stresses (¶[0073]).
Moon in view of Shu and Burke does not explicitly disclose:
wherein, at the first edge an edge of the polymer layer that faces in the first direction extends further in the first direction than an edge of the display panel that faces in the first direction.
However, Zhu028 teaches:
wherein, an edge of the polymer layer (141, fig. 1, ¶[0065]) that faces in a first direction extends further in the first direction than an edge of the display panel that faces in the first direction (as disclosed in annotated fig. 1 below).

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include an edge of the polymer layer that faces in the first direction extends further in the first direction than an edge of the display panel that faces in the first direction as taught by Zhu028, in to the electronic device of Moon as modified by Zhu and Burke, in order to disperse stress, and therefore, the bending region would not deform extremely easily, which prevents broken wires and improves production rate (¶[0036]).
Regarding claim 3, Moon in view of Zhu, Burke and Zhu028 teaches the limitations of claim 1, and Zhu further teaches: wherein the first filling member comprises a molding solution that is cured (“700 may be made of a foam material such as PU foam, CR foam, XPE foam, and the like”, ¶[0055]).
Regarding claim 4, Moon in view of Zhu, Burke and Zhu028 teaches the limitations of claim 1, and Moon further teaches:
wherein the flexible display further comprises:
a support plate (450, fig. 8a) under the polymer layer.
Regarding claim 6, Moon in view of Zhu, Burke and Zhu028 teaches the limitations of claim 4, but does not explicitly disclose:
wherein, at the first edge, an edge of the support plate that faces in the first direction extends further in the first direction than an edge of the polymer layer that faces in the first direction.
However, Zhu028 teaches:
a first edge (edges of 141, 142, and 143, fig. 1) faces in a first direction towards the bending part (as disclosed in annotated fig. 1 above, Zhu028), and
wherein, at the first edge, an edge of a support plate (143, fig. 1) that faces in the first direction extends further in the first direction than an edge of the polymer layer (141, fig. 1) that faces in the first direction (as disclosed in annotated fig. 1 above, Zhu028).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include an edge of the support plate that faces in the first direction extends further in the first direction than an edge of the polymer layer that faces in the first direction as taught by Zhu028, in to the electronic device of Moon as modified by Zhu and Burke, in order to disperse stress, and therefore, the bending region would not deform extremely easily, which prevents broken wires and improves production rate (¶[0036]).
Regarding claim 7, Moon in view of Zhu, Burke and Zhu028 teaches the limitations of claim 1, and Moon further teaches:
further comprising an adhesive member (P1, fig. 8a) blocking the second space (see annotated figs. 8a above).
Moon in view of Zhu does not explicitly teach:
the adhesive member between at least a part of the window layer and the bending part at the first edge and blocking the second space.
However, Moon teaches:
an adhesive member (P2, P3, fig. 8a) between at least a part of the window layer (410, fig. 8a) and the bending part (432, fig. 8a) at a first edge (see annotated figs. 8a above).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include an adhesive member between at least a part of the window layer and the bending part at the first edge and blocking the second space, since such a modification would have involved a mere change in the size of a component (MPEP 2144.04). A change in size is generally recognized as being within the level of ordinary skill in the art.
Regarding claim 8, Moon in view of Zhu, Burke and Zhu028 teaches the limitations of claim 1, and Moon further teaches: wherein the window layer comprises a first layer of a polymer material (411, fig. 8a, ¶[0088]) and a second layer of a glass material (412, fig. 8a, ¶[0088]),
wherein the second layer is between the first layer and the bending part (fig. 8a).,
and
wherein the electronic device (300) further comprises an adhesive member (P1, fig. 8a).
Moon in view of Zhu does not explicitly teach:
wherein the electronic device further comprises an adhesive member between at least a part of the first layer and the bending part at the first edge and blocking the second space.
However, Moon further teaches:
an adhesive member (P2, P3, fig. 8a) between at least a part of the window layer (410, fig. 8a) and the bending part (432, fig. 8a) at a first edge (see annotated figs. 8a above).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include an adhesive member between at least a part of the window layer and the bending part at the first edge and blocking the second space, since such a modification would have involved a mere change in the size of a component (MPEP 2144.04). A change in size is generally recognized as being within the level of ordinary skill in the art.
Regarding claim 10, Moon in view of Zhu, Burke and Zhu028 teaches the limitations of claim 1, but does not explicitly teach:
further comprising a second filling member within a second space.
However, Zhu further teaches:
further comprising a second filling member (500, fig. 3) within a second space (the space occupied by 500, fig. 8).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include a second filling member within a second space, in order to provide a better effect of cushioning and protection effect, and a degree of deformation and depression of the window layer may be reduced. Therefore, the extrusion force of the window layer to the flexible display panel is reduced, thereby reducing circuit breakage on the flexible display panel (¶[0028], ¶[0063]).
Regarding claim 11, Moon in view of Zhu, Burke and Zhu028 teaches the limitations of claim 10, and Zhu further teaches: wherein the second filling member comprises a cured molding solution (¶[0039]).
Regarding claim 13, Moon in view of Zhu, Burke and Zhu028 teaches the limitations of claim 1, and Moon further teaches: wherein the first housing (310) comprises:

a second support member (annotated as ‘1231’ in annotated fig. 4a below) that extends from the second lateral member, and wherein the flexible display is supported by the first support member and the second support member (as understood upon examination of fig. 4a; “ the flexible display 400 may be disposed to receive support of at least a partial area of the first housing 310, the hinge module 364, and the second housing 320”, ¶[0069]).
Regarding claim 14, Moon in view of Zhu, Burke and Zhu028 teaches the limitations of claim 13, and the combination further teaches: wherein the first filling member is within a space between the second lateral member and the second support member (via the combination, and as disclosed upon examination of annotated fig. 4a above, fig. 8a, and ¶[0069], Moon).
Regarding claim 15, Moon in view of Zhu, Burke and Zhu028 teaches the limitations of claim 13, but does not explicitly disclose:
wherein a size or a shape of the first filling member is defined by a space between the second lateral member and the second support member.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include a size or a shape of the first filling member is defined by a space between the second lateral member and the second support member, since such a modification would have involved a mere change in the size of a component (MPEP 2144.04). A change in size is generally recognized as being within the level of ordinary skill in the art. The modification would allow support for the filling member to exert a cushioning effect to internal components of the electronic device.
Regarding claim 16, Moon teaches: an electronic device comprising:
a first housing (310, fig. 4a);
a second housing (320, fig. 4a);
a hinge device (364, fig. 4a) connecting the first housing and the second housing to be foldable relative to each other (¶[0069]-[0070]);
and
a flexible display (400, fig. 4a) supported by the first housing and the second housing (¶[0069]),
wherein the flexible display comprises:
a window layer (410, fig. 8a);
a display panel (430) laminated under the window layer (fig. 8a);
a polymer layer (440, fig. 8a) under the display panel (430);
a bending part (432, fig. 8a) bent from the display panel to a rear surface of the flexible display at a first edge (unnumbered, annotated as 401, in annotated fig. 8a below) of the flexible display, the bending part comprising an inner surface facing the first edge and an outer surface opposite to the inner surface (see annotated fig. 8a below), and the first edge faces in a first direction (‘FD’ in annotated fig. 8A below) towards the bending part;

Moon does not explicitly teach:
a first filling member in a first space, within the electronic device, such as to surround at least a part of the first edge together with the bending part; and
a second filling member in a second space, between the window layer and the display panel, and formed of a material that is softer than a material of the first filling member,
wherein the first filling member covers at least a portion of the inner surface and at least a portion of the outer surface of the bending part,
wherein, at the first edge an edge of the polymer layer that faces in the first direction extends further in the first direction than an edge of the display panel that faces in the first direction.
However, Zhu teaches:
a first filling member (700, comprised of PU foam, CR foam, XPE foam, and the like ¶[0055] and 600, fig. 3), in a first space (space occupied by 700 and 600) within an electronic device (300), such as to surround at least a part of a first edge (as disclosed in fig. 3) together with a bending part (320, fig. 3); and
a second filling member (500, fig. 3) in a second space (space occupied by 500), between a window layer (400, figs. 1-3) and a display panel (200 and 300, fig. 3).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include a first filling member in a first space within the electronic device, such as to surround at least a part of the first edge together with the bending part, and a second filling member in a second space, between the window layer and the display panel, in order to provide a more stable support effect on an internal structure of the bending part, and therefore, the bending part may not be easily damaged due to deformation (¶[0055]), and a better effect of cushioning and protection effect, and a degree of deformation and depression of the window layer may be reduced. Therefore, the extrusion force of the window layer to the flexible display panel is reduced, thereby reducing circuit breakage on the flexible display panel (¶[0028], ¶[0063]).
Moon in view of Zhu does not explicitly teach:
the second filling member formed of a material that is softer than a material of the first filling member, and
wherein the first filling member covers at least a portion of the inner surface and at least a portion of the outer surface of the bending part,
wherein, at the first edge an edge of the polymer layer that faces in the first direction extends further in the first direction than an edge of the display panel that faces in the first direction.
However, Burke teaches:
a display (816, fig. 8A) comprising a bending part (811 and 814, fig. 8a) bent from the display panel to a rear surface of the flexible display at a first edge (unnumbered, see annotated fig. 8a below) of the flexible display; wherein a first filling member (821 and 823, fig. 8a, ¶[0073]-¶[0079]; note Burke expressly teaches the materials may be the same material therefore analogous to applicant’s single material on two sides of the curved portion) covers at least a portion of an inner surface and at least a portion of an outer surface of the bending part (see annotated fig. 8a).

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to Moon’s electronic device as modified by Zhu, with Burke’s teaching, so that the first filling member covers at least a portion of the inner surface and at least a portion of the outer surface of the bending part, in order to reinforce or bolster the bending part of the display panel, against external forces or stresses (¶[0073]).
Moon in view of Zhu and Burke does not explicitly teach:
the second filling member formed of a material that is softer than a material of the first filling member,
wherein, at the first edge an edge of the polymer layer that faces in the first direction extends further in the first direction than an edge of the display panel that faces in the first direction.
However, Burke further teaches:
a second filling member (823, figs. 8a-8b) in a second space (see annotated fig. 8a) formed of a material that is softer than a material of the first filling member (a modulus of the second filling member 823 (¶[0079]) is smaller than a modulus of a first filling member 821, figs. 8a-8b, ¶[0074]).

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to set the second filling member formed of a material that is softer than a material of the first filling member of Moon in view of Zhu and Burke, as taught by Burke, in order for the second filling member not transmit load to the display assembly, and act as shock absorber, while being hard enough avoid decreasing display reliability (¶[0079]).
Moon in view of Shu and Burke does not explicitly disclose:
wherein, at the first edge, an edge of the polymer layer that faces in the first direction extends further in the first direction than an edge of the display panel that faces in the first direction.
However, Zhu028 teaches:
PNG
media_image5.png
437

media_image5.png
Greyscale
wherein, an edge of the polymer layer (141, fig. 1, ¶[0065]) that faces in a first direction extends further in the first direction than an edge of the display panel that faces in the first direction (as disclosed in annotated fig. 1 below).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include an edge of the polymer layer that faces in the first direction extends further in the first direction than an edge of the display panel that faces in the first direction as taught by Zhu028, in to the electronic device of Moon as modified by Zhu and Burke, in order to disperse stress, and therefore, the bending region would not deform extremely easily, which prevents broken wires and improves production rate (¶[0036]).
Regarding claim 20, Moon in view of Zhu, Burke, and Zhu028 teaches the limitations of claim 16, and Moon further teaches: wherein the flexible display further comprises an additional layer (450, fig. 8a) under the polymer layer (440),
wherein an edge of the additional layer, that faces in the first direction, is farther in the first direction than the edge of the polymer layer that faces in the first direction (fig. 8A teaches this limitation).
Regarding claim 21, Moon in view of Zhu, Burke, and Zhu028 teaches the limitations of claim 1, but does not explicitly teach:
wherein the first filling member comprises an epoxy series material.
However, Burke teaches:
wherein a first filling member (821 and 823, fig. 8a, ¶[0073]-¶[0079]; note Burke expressly teaches the materials may be the same material therefore analogous to applicant’s single material on two sides of the curved portion) comprises an epoxy series material (¶[0079]).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to apply Burke’s teaching into Moon in view of Zhu, Burke, and Zhu028 such that the first filling member comprises an epoxy series material, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious engineering choice (MPEP 2144.07).
Regarding claim 23, Moon in view of Zhu, Burke, and Zhu028 teaches the limitations of claim 22, and Burke further teaches:
wherein a first filling member (821 and 823, fig. 8a, ¶[0073]-¶[0079]; note Burke expressly teaches the materials may be the same material therefore analogous to applicant’s single material on two sides of the curved portion) comprises an epoxy series material (¶[0079]).
Claims 22 is rejected under 35 U.S.C. 103 as being unpatentable over Moon et al (US 20210116964; “Moon” hereinafter), in view of Zhu (US 20230217603; “Zhu” hereinafter), and Burke et al (US 20220061166; “Burke” hereinafter), Zhu (US 20220208028; “Zhu028” hereinafter), as applied to claim 10, and further in view of Choi et al (US 20200266284; “Choi” hereinafter).
Regarding claim 22, Moon in view of Zhu, Burke, and Zhu028 teaches the limitations of claim 10, but does not explicitly teach:
wherein the second filling member comprises a silicone series material.
However, Choi teaches:
a support portion (833c, fig. 9) comprises a silicone series material (¶[0109]).
It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to apply Choi’s teaching into Moon in view of Zhu, Burke, and Zhu028 such that the second filling member comprises a silicone series material, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious engineering choice (MPEP 2144.07).
Response to Arguments
Applicant's arguments filed 4/21/2026 have been fully considered but they are not persuasive. Applicant’s first argument:
“For example, with reference, Fig. 8A of Moon, reproduced below with annotation, a
portion of an alleged first space defined by and between the inner surface of the alleged bending part (432) and at least a portion of the alleged first edge of the alleged flexible display (400) (the portion including an edge of the alleged polymer laver (440)), includes an area 4401 that is recessed in the direction opposite to the alleged bending part (432) in comparison to the alleged display panel (430), and the area 4401 overlaps with the alleged second space in a front-rear direction of the alleged flexible display (400).
At least in view of the above, Applicant respectfully submits that Moon does not disclose or suggest the above features as claimed.
Examiner’s Response:

As disclosed in the previous and current office action, the mapping of the first space and second space complies with the non-overlapping limitation as seen below in annotated figure 8A, and does not comprise the entire area 4401. Furthermore, upon a full review of Moon’s disclosure, the remaining limitation of amended claims 1 and 16 are also taught by Moon, Zhu, Burke and Zhu028.
Applicant’s second argument:
“Applicant respectfully submits that independent claim 16 is patentable over the
combination of cited references, at least for reciting "wherein, at the first edge, an edge of the
polymer layer that faces in the first direction extends further in the first direction than an
edge of the display panel that faces in the first direction, and wherein a portion of the first
space is defined by and between the inner surface of the bending part and at least a portion
of the first edge of the flexible display, the portion of the first edge extending from a front
surface of the display panel to the rear surface of the flexible display, and the portion comprising the edge of the polymer layer," at least for similar reasons as discussed above with respect to independent claim 1.”
Examiner’s Response:
Moon in view of Zhu, Burke, and Zhu028 teaches the limitations of amended claim 1. Refer to the mapping of claim 16 presented in this office action, and fig. 8A of Moon below, where the polymer layer 440 and the first edge placement meet the limitations of clam 1, in combination with Zhu, Burke, and Zhu028.
