Office Action

§102 §103
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 . Specification The disclosure is objected to because of the following informalities: The terms “Polyvinyl Chloride” (pg 4, line 20), “Thermoplastic Polyurethane” (pg 4, line 20), and “Polyethylene Terephthalate” (pg 5, lines 5-6) should not be capitalized since these polymers are not proper nouns. Appropriate correction is required. Claim Objections Claims 9 and 10 are objected to because of the following informalities: The terms “Polyvinyl Chloride” (claim 9, line 3), “Thermoplastic Polyurethane” (claim 9, line 4), and “Polyethylene Terephthalate” (claim 10, line 3) should not be capitalized since these polymers are not proper nouns. Appropriate correction is required. Claim Interpretation Independent claim 1 is directed to a multilayer film structure that recites the layers and structure using relative functional claim language. For example, it is recited that the multilayer structure comprises a thermal-insulation surface film. A broadest reasonable interpretation of this surface film would include any polymeric or metallic film, since any polymeric and metallic film would provide at least some thermal insulating properties. This same issue is noted for the other layers of the multilayer film structure, i.e., soft statics adsorption film, protective base film, anti-abrasion coating, etc. While claiming these layers with relative functional terminology is permitted, the Examiner is noting this interpretation to clarify the record as to the breadth of the present claims. 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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-2 and 7-10 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by CN-106183276 (referred to hereinafter as CN ‘276). An English machine translation of CN ‘276 is provided and relied upon for the below prior art rejection. Regarding claim 1, CN ‘276 discloses a heat insulating film that reflects the sunlight and absorb and adsorbs the energy of the sunlight (lines 44-45) that comprises a thermal-insulation film (Figure 1, ref #12), a soft statics adsorption film (Figure 1, ref #14), and a protective base film (Figure 1, ref #2). Regarding claim 2, CN ‘276 discloses providing an anti-abrasion and wear-resistant coating on the upper surface of the thermal-insulation film (Figure 1, ref #11). Regarding claims 7 and 8, CN ‘276 discloses using an adhesive coating to bond the thermal-insulation film with the soft statics adsorption film (Figure 1, ref #13). Regarding claim 9, the soft statics adsorption film can be made of TPU (line 73). Regarding claim 10, the protective base film can be made of PET (line 72). Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 3-6 are rejected under 35 U.S.C. 103 as being unpatentable over CN ‘276 in view of TW-M594056 (referred to hereinafter as TW ‘056). An English machine translation of TW ‘056 is provided and relied upon for the below prior art rejection. Regarding claims 3-6, CN ‘276 does not disclose that the insulation film is provided with a nano-metal reflection coating, an IR heat insulation coating, and a UV absorbent coating. However, TW ‘056, which is also directed to heat insulating structures for glass, discloses that it is known in the art to provide glass heat insulation films with nano-metal reflection coatings (ref #14), IR heat insulation coatings (ref #12 & ref #12a), and UV absorbent coatings (ref #12 and ref #12a). TW ‘056 discloses that such insulation films have good thermal insulation effects (line 27-28). It would have been obvious to one of ordinary skill in the art to have provided the multilayer heat insulation film of CN ‘726 with a nano-reflection coating, IR heat insulation coating, and a UV absorbent coating, motivated by the desire to a heat insulation film having good thermal insulation properties, as taught by TW ‘056.
