Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of KO. Applicant’s arguments, see Remarks, pages 13-15, filed 06/02/2026, with respect to independent claim(s) 11, and its dependent claims, 12, and 23-26 have been fully considered and are persuasive. The rejection of claim(s) 12, and 23-26 have been withdrawn. Regarding Independent Claim 1. The Applicant argues (see Remarks, pages 11-12) that KIM fails to disclose or suggest the amended features of claim 1, now recites, “a first contact electrode electrically…light emitting element; and a second contact electrode electrically…light emitting element, wherein the first contact electrode…(1-2)th electrode, and the second contact electrode…the (2-2)th electrode.” The Examiner agrees that the arguments are persuasive and therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made as mentioned in the above paragraph. For instance, the prior-art of KO teaches a display device (Fig. 1, 100) including a display area (Fig.1, 110, display panel), the display device (Fig. 1, 100) comprising: a first contact electrode (Fig. 3B, CNE1, first connection electrode) electrically connecting ([0089], [0094], [0096]) the first electrode (Fig. 3B, E1) and the light emitting element (Fig. 3B, ED); and a second contact electrode (Fig. 3B, CNE2, second connection electrode) electrically connecting ([0089], [0094], [0096]) the second electrode (Fig. 3B, E2) and the light emitting element (Fig. 3B, ED), wherein the first contact electrode (Fig. 3B, CNE1, first connection electrode) is on the (1-2)th electrode (Fig. 3B, CPE1, first capping electrode) and is electrically connected ([0089], [0094], [0096]) to the (1-2)th electrode (Fig. 3B, CPE1, first capping electrode), and the second contact electrode (Fig. 3B, CNE2, second connection electrode) is on the (2-2)th electrode (Fig. 3B, CPE2, second capping electrode) and is electrically connected ([0089], [0094], [0096]) to the (2-2)th electrode (Fig. 3B, CPE2, second capping electrode). Regarding Claims 3, 5-10, and 21-22. The dependent claims 3, 5-10, and 21-22 follow similar arguments as Claim 1, upon further consideration, a new-grounds of rejection is made based on the prior-art mentioned above. Regarding Independent Claim 11. The Applicant argues (see Remarks, pages 13-14) that none of the prior art disclose or suggest the amended features to claim 11, now recites, “a pad structure comprising: the first pad pattern has a planar upper surface and side surface, a lowermost surface of the third pad pattern…second pad pattern, and…continuously covers the planar…side surface of the first pad pattern.” The Examiner agrees that the arguments are persuasive and therefore, the rejection has been withdrawn. Regarding Claims 12, and 23-26. The dependent claims 12, 23-26 follow similar arguments as Claim 11, and therefore the rejection has been withdrawn.

KIM2 teaches the display device (Fig. 2, the organic light-emitting display apparatus, [0032]), wherein: the second pad pattern (Fig. 3, 403, cover pad electrode) covers a side surface (annotated Figure 3) of the first pad pattern (Fig. 3, 401, first lower pad electrode) such that the first pad pattern is not exposed (annotated Figure 3, [0091]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA ) to have KIM as modified by LEE, KANG and KO to incorporate the teachings of KIM2, such that the display device, wherein: the second pad pattern covers a side surface of the first pad pattern such that the first pad pattern is not exposed, so that the cover pad electrode, 403 may be formed of a material having a stronger corrosion resistance than a material forming the first lower pad electrode, 401 thus act as a corrosion protection layer (KIM2, [0091]). PNG media_image6.png 911 1031 media_image6.png Greyscale Regarding Claim 8, KIM as modified by LEE, KANG and KO teaches the display device of claim 4. KIM as modified by LEE, KANG and KO does not explicitly disclose the display device, further comprising a third pad pattern electrically connected to the second pad pattern, the third pad pattern being disposed on the second pad pattern; and a fourth pad pattern electrically connected to the third pattern, the fourth pad pattern being disposed on the third pad pattern, wherein the first contact electrode and the third pad pattern include a same material, and the second contact electrode and the fourth pad pattern include a same material. KIM2 teaches the display device (Fig. 2, the organic light-emitting display apparatus, [0032]), further comprising: a third pad pattern (Fig. 3, 502, center pad electrode) electrically connected (annotated Figure 3) to the second pad pattern (Fig. 3, 403, cover pad electrode), the third pad pattern being disposed on the second pad pattern; and a fourth pad pattern (Fig. 3, 503, second upper pad electrode) electrically connected to the third pattern (Fig. 3, 502, second center pad electrode), the fourth pad pattern being disposed on the third pad pattern, wherein the first contact electrode (Fig. 3, 202/212, second center anode electrode/second center auxiliary electrode) and the third pad pattern (Fig. 3, 502, second center pad electrode) include a same material (metals like Cu/Ag, [0052], [0060], [0096]), and the second contact electrode (Fig. 3, 203/213, second upper anode electrode/second upper auxiliary electrode) and the fourth pad pattern (Fig. 3, 503, second upper pad electrode) include a same material (transparent conductive material, ITO, [0050], [0061], [0096]). PNG media_image7.png 899 1021 media_image7.png Greyscale Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA ) to have KIM as modified by LEE, KANG and KO to incorporate the teachings of KIM2, such that the display device, further comprising a third pad pattern electrically connected to the second pad pattern, the third pad pattern being disposed on the second pad pattern; and a fourth pad pattern electrically connected to the third pattern, the fourth pad pattern being disposed on the third pad pattern, wherein the first contact electrode and the third pad pattern include a same material, and the second contact electrode and the fourth pad pattern include a same material, so that the pad electrode, 502 may be formed of the same material which has good corrosion resistance, the second center pad electrode, 502 may be prevented from being corroded (KIM2, [0097]). Claim(s) 22 is/are rejected under 35 U.S.C. 103 as being unpatentable over KIM, in view of LEE, KANG, and KO as applied to claims 1, 3-4, 9-10, 21 as above, and further in view of Jonghyeok Im et al, (hereinafter IM), US 20190097161 A1. Regarding Claim 22, KIM as modified by LEE, KANG and KO teaches the display device of claim 1. KIM as modified by LEE, KANG and KO does not explicitly disclose the display device, wherein a lower surface of the second pad pattern directly contacts an upper surface and a side surface of the first pad pattern in their entirety. IM teaches in Figure 11J, the display device (Fig. 3, OLED display device, [0034]) of claim 1, wherein a lower surface (annotated Figure 11J) of the second pad pattern (Fig. 11J, 519c, third upper sustaining electrode layer, [0439]) directly contacts (annotated Figure 11J) an upper surface and a side surface of the first pad pattern in their entirety (Fig. 11J, 519b/519a, second/first upper sustaining electrode layer, [0439]). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA ) to have KIM as modified by LEE, KANG and KO to incorporate the teachings of IM, such that the display device, wherein a lower surface of the second pad pattern directly contacts an upper surface and a side surface of the first pad pattern in their entirety. This arrangement of planar geometry of the first/second upper sustaining electrode layer (519a/519b) having low resistive material such as Cu, encapsulated with the corrosive resistant third upper sustaining electrode layer (519c), thus protect the first/second upper sustaining electrode layer (519a/519b) from exposing to the passivation layer (515c), moisture and oxygen in spite of the third upper sustaining layer is (519c) is being exposed to the exterior (IM, [0439-0443]). PNG media_image8.png 738 1005 media_image8.png Greyscale Allowable Subject Matter Claim(s) 11-12, and 23-26 are allowed. The following is a statement of reasons for the indication of allowable subject matter: Regarding Independent Claim 11. Seung Hyun Lee et al, (hereinafter LEE), and Sejune Kim et al, (hereinafter KIM2), US 20160351846 A1, are the closes prior art of record that teaches a pad structure of a display device. The cited prior art of record, either singly or in proper combination, does not teach or make obvious, along with the other claimed features, more specifically the amended limitations to claim 11, now recites, “a pad structure comprising: the first pad pattern has a upper surface and side surface, a lowermost surface of the third pattern contacts an uppermost surface of the second pad pattern, and the second pad pattern directly and continuously covers the planar upper surface and the side surface of the first pad pattern.” The cited art fails to disclose a pad structure comprising: a first pad pattern disposed on a substrate; a second pad pattern electrically connected to the first pad pattern, the second pad pattern being disposed on the first pad pattern; an insulating layer being not contacted with the first pad pattern, covering a portion of the second pad pattern, and comprising a contact hole exposing the second pad pattern; and a third pad pattern extending into the contact hole of the insulating layer and electrically connected to the second pad pattern through the contact hole and the third pad pattern being disposed on the second pad pattern, wherein: the second pad pattern includes a transparent conductive material and covers a side surface of the first pad pattern such that the first pad pattern is not exposed, the first pad pattern has a planar upper surface and side surface, at least a portion of the insulating film is between the second pad pattern and the third pad pattern, an upper surface of the second pad pattern is directly adjacent to the contact hole, a lowermost surface of the third pad pattern contacts an uppermost surface of the second pad pattern, and the second pad pattern directly and continuously covers the planar upper surface and the side surface of the first pad pattern. More specifically, the prior art lacks the teaching of an amended features, “a pad structure comprising: the first pad pattern has a upper surface and side surface, a lowermost surface of the third pattern contacts an uppermost surface of the second pad pattern, and the second pad pattern directly and continuously covers the planar upper surface and the side surface of the first pad pattern.” Claim(s) 12, and 23-26 depend on claim 11, and are allowed for the same reasons. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 20200144453 A1 – Figure 5 STATEMENT OF RELEVANCE – The first contact electrode, CTE1 and the second contact electrode, CTE2, are electrically connected the light emitting element, ED and first protruding electrode, PE1 and the second protruding electrode, PE2 respectively.
