Response to Amendment Applicant's arguments filed 03/16/2026 have been fully considered but they are not persuasive. It is noted that Applicant's arguments are related to the amended subject matter, simply stating the new amendments are not seen in the prior art. As is seen in the new rejection above, these amended features are disclosed by the prior art by new prior art, Kim (US-20080278070). All the arguments relating to limitations previously presented and rejected in the last arguments will be addressed below. For claim 1 .... "Applicant's amendments and arguments were persuasive. Upon further search and consideration a new rejection using a different interpretation of Takeya et al. in combination with newly cited reference to Kim has been presented with regard to claim 1." For page 12 of the arguments, Applicant states that it would not have been easy to combine Tokeya et al and Cho et al. due to the structurally different inventions. Although that it is agreed that both arts are different inventions, the claim language reads for the proximity of the upper line patterns and the type of elasticity the material contains which is what is combined, not the full invention, therefore, the combination is proper in relation to display devices and the design described in Cho would aid to increase device versatility, reduce device failure, and to increase the circuits lifetime (as stated in the rejection above). 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.
