Regarding claim 14, Shiwei discloses a display substrate comprising a light emitting diode chip of claim 1 (display device having light emitting element on substrate; abstract). Regarding claim 15, Shiwei discloses a display device comprising a light emitting diode chip of claim 1 (display device having light emitting element; abstract). Response to Arguments Applicant's arguments filed October 28, 2025 have been fully considered. Applicant presents substantive amendments to claim 1 with corresponding arguments. Specifically, Applicant argues that amended claim 1 overcomes the 35 USC 102 rejection using Shiwei. However, the only new limitation amended into the claim set is the removal of the ‘and/or’ modifier from the limitation “wherein the first sub-side surface is closer to the base substrate than the second sub-side surface; and/or, the inclination α is greater than the inclination θ” which consequently requires disclosure of both claim elements of the limitation. This limitation is disclosed by Shiwei’s Fig. 2 in that the layer 500 has two sub-side surfaces that have different inclination angles with one being greater than the other relative the substrate 100. Applicant asserts that the sidewall of layer 500 is entirely inclined at a uniform angle and that the sidewall is not configured to include two sub-parts with different inclination angles. However, Fig. 2 clearly shows layer 500 having a left and right side part with different inclination angles relative substrate 100. Applicant further cites paragraphs [0057]-[0058] and provides a lengthy analysis of their contents with regard to the isolation groove 400 in relation to Figs. 1-3. However, Examiner cited these paragraphs in order to demonstrate that if the bridging metal 216 has these inclination angles, then Fig. 2 shows the layer 500 having the same inclination angles given metal 216 is overlaid upon layer 500 in the same orientation relative the substrate 100. Applicant further asserts that Shiwei is silent about the portion of the sidewall of the layer 500 close to the substrate 100 and the portion away from the substrate 100 having different inclination angle. However, Fig. 2 of Shiwei and corresponding paragraphs [0057]-[0058] disclose left and right portions (each having terminal ends with different distances away from substrate 100) of layer 500 having different inclination angles (one inclined in a leftward direction and the other inclined in a rightward direction, which means one angle is larger than the other) relative the substrate 100. Therefore, amended claim 1 is disclosed by Shiwei and the corresponding 35 USC 102 rejection is maintained. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
