Regarding claim 5, Smeeton/Cao discloses the flexible glass of claim 1. Cao further teaches (fig.8) wherein a spacing between two adjacent first holes among the plurality of first holes decreases based on a distance to the at least one of the first side edge or the second side edge. date of the claimed invention to combine a decreasing spacing between two adjacent first holes of Cao to device of Smeeton in order to disperse stresses on both sides thereof more evenly, thereby avoiding damage to the supporting structure ([0051] and Cao) Regarding claim 6, Smeeton/Cao discloses the flexible glass of claim 1. Smeeton discloses wherein the compensating material is further provided on at least one surface of the flexible glass (fig.1B). Regarding claim 7, Smeeton/Cao discloses the flexible glass of claim 1. Smeeton discloses a glass layer (112) provided from the flexible area to the planar area; and a coating layer (114) provided on at least one surface of the glass layer (fig.1B). Regarding claim 8, Smeeton/Cao discloses the flexible glass of claim 7. Smeeton discloses wherein the plurality of first holes are provided in the coating layer (fig.1B). Regarding claim 9, Smeeton/Cao discloses the flexible glass of claim 7. Smeeton discloses wherein the plurality of first holes (H1) are provided in the coating layer, and wherein the glass layer comprises a plurality of second holes (H2) corresponding to the plurality of first holes. PNG media_image3.png 392 794 media_image3.png Greyscale Regarding claim 10, Smeeton/Cao discloses the flexible glass of claim 9. Smeeton discloses further comprising a compensating material provided in at least some of the plurality of second holes, wherein the compensating material is configured to compensate for a refractive index deviation of transmitted light in the flexible area (col 6, lines 35-55). Regarding claim 11, Smeeton/Cao discloses the flexible glass of claim 1. Smeeton discloses wherein the planar area is provided on both sides of the flexible area, respectively, and wherein as the flexible area is moved, the planar areas are configured to: be disposed side by side, each on one side of the other, with the flexible area disposed therebetween, or be disposed to at least partially face each other (fig.1A). Regarding claim 12, Smeeton/Cao discloses the flexible glass of claim 1. Smeeton discloses wherein the flexible area is provided side by side on one side of the planar area and configured to be moved to a position in which the flexible area at least partially faces the planar area at a specified spacing (fig.1F). Claims 13-15 are rejected under 35 U.S.C. 103 as being unpatentable over Smeeton et al in view of Cao et al and further in view of Koo et al (US Patent No. 12108620 B2 and Koo hereinafter) Regarding claim 13, Smeeton/Cao discloses the flexible display comprises the flexible glass of claim 1, but does not explicitly disclose an electronic device comprising: a first housing; a second housing coupled to the first housing and configured to move with respect to the first housing; and a flexible display comprising a first display area provided on the first housing, and a folding area extending from the first display area and configured to be movable into a planar shape and a curved shape according to movement of the second housing, and wherein the flexible area of the flexible glass is provided in the folding area. However, Koo teaches (figs. 1A-1D) an electronic device comprising: a first housing (144); a second housing (144) coupled to the first housing and configured to move with respect to the first housing; and a flexible display (118) comprising a first display area provided on the first housing, and a folding area (180) extending from the first display area and configured to be movable into a planar shape and a curved shape according to movement of the second housing, and wherein the flexible area of the flexible glass is provided in the folding area.
