Examiner agrees with Applicant; However, after a new line of search and consideration of the prior art, the amended limitations of independent claims 1 and 14 can be overcome by primary reference Chang et al. (KR 20190104277 A), and newly cited source Son (KR 20110061435 A ). Applicant argues on page 5, Section: Rejections under 35 U.S.C. §§102 and 103, in remarks filed February 18, 2026 that claims dependent on independent claims 1 and 14 should now be in condition for allowance. Examiner disagrees with Applicant for at least the reasons mentioned above. Applicant argues on page 5, Section: New Claims, in remarks filed February 18, 2026 that newly added claims 21-23 should now be in condition or allowance. Examiner disagrees with Applicant for at least the reasons mentioned above. In summary, the amended limitations of independent claims 1 and 14 can be overcome by primary reference Chang et al. (KR 20190104277 A) and newly cited source Son (KR 20110061435 A). All claims directly or indirectly dependent on independent claims 1 and 14 are also rejected for at least the reasons mentioned above.
