Office Action

§112
DETAILED ACTION Notice of Pre-AIA or AIA Status 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Objections 2. Claims 1-5 are objected to because of the following informalities: In claim 1, line: “characterized in that :comprising” In claim 1, lines 2: “a release agent coating (3), The antistatic coating (2)” In claim 1, line 13: “pf 3-acetylbenzoic acid” In claim 2, line 1: “characterized in that:wherein” In claim 3, line 1: “characterized in that:wherein” In claim 4, line 1: “characterized in that:wherein” In claim 5, line 1: “characterized in that:wherein” Appropriate correction is required. 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. 3. Claims 2-4 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. Claim 2 recites that “the antioxidant is selected from an antioxidant 1010, an antioxidant 1024, or an antioxidant 2246.” It is unclear what is meant by “antioxidant 1010, an antioxidant 1024, or an antioxidant 2246.” Claim 3 recites that “the leveling agent is selected from one of the leveling agent 440, the leveling agent DC 57, and the leveling agent DC3”. .” It is unclear what is meant by “the leveling agent 440, the leveling agent DC 57, and the leveling agent DC3”. Further, there is insufficient antecedent basis for “the leveling agent 440”, “the leveling agent DC 57”, and “the leveling agent DC 3” in the claim. Claim 4 recites that “the substrate layer is one of a PET layer, a TPU layer, a PAR layer, a CPP layer, a PVC layer, a SEPS layer and an SEBS layer.” The Examiner recommends reciting the name of each polymer in full to avoid any ambiguity. Appropriate correction or clarification is required. Conclusion 4. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The closest prior, CN 111978582 A, discloses preparation of antistatic films for electronic products comprising 100 pts. wt. polyurethane resin, 40-60 pts. wt. polyvinyl alcohol, 2-4 pts. wt. sodium octyl sulfate, 1-3 pts. wt. N-ethyl-N-(3-sulfopropyl)-3-methylaniline sodium salt, 8-12 pts. wt. dioctyl terephthalate, 40-60 pts. wt. n-butanol, 20-30 pts. wt. isobutyl acetate, 0.5-1 pt. wt. castor oil polyoxyethylene ether, 0.3-0.8 pt. wt. triethylenetetramine, 0.5-1.5 pts. wt. silane coupling agent, 0.6-2 pts. wt. antioxidant and 0.4-1 pt. wt. leveling agent however fail to disclose or render obvious the combination of the above components with 8-12 parts of dibutyl sebacate, 0.8-1.5 parts of hydroxyethyl cellulose, and 0.3-0.8 parts of 3-acetylbenzoic acid. 5.
