Office Action

§102 §112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Election/Restrictions Claims 10 and 20 are withdrawn. Applicant elects Species 3 (Fig. 6), drawn to claims 1-9 and 11-19 with traverse as being drawn to a nonelected species, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 12/09/2025 is acknowledge, However, the examiner is not persuaded as the Species listed do not relate to a single general inventive concept under PCT Rule 13.1. because they lack the same or corresponding special technical features for the following reasons: they are not novel over prior art, Kim et al. 20230374646, in the rejection below. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-9 and 11-19 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claims 1-3, 5, 8, 11-13, 15, and 18 recite multiple “the metal barrier part” lack antecedent basis. As such the claim is unclear and indefinite. Claims 1, 3-5, 11 and 13-15 last line recites “the insulation part” lack antecedent basis. As such the claim is unclear and indefinite. Claim 5 recites “the organic insulation layer comprises at least one insulation part covering a corresponding side of the metal barrier part” is unclear and indefinite if this recitation is the same “the organic insulation layer comprises at least one insulation part covering a corresponding side of the metal barrier part” recited in claim 1. As such the claim is unclear and indefinite. Claim 15 recites “the organic insulation layer comprises at least one insulation part covering a corresponding side of the metal barrier part” is unclear and indefinite if this recitation is the same “the organic insulation layer comprises at least one insulation part covering a corresponding side of the metal barrier part” recited in claim 11. As such the claim is unclear and indefinite. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-9 and 11 -19 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Kim et al. 20230374646.
