Office Action

§103
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 . Priority Receipt is acknowledged of certified copies of papers required by 37 CFR 1.55. Information Disclosure Statement The information disclosure statements (IDSs) submitted on 11/17/2023 is being considered by the examiner. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1-2 and 6-8 are rejected under 35 U.S.C. 103 as being unpatentable over Sungkyunkwan University (KR 10-2325518 B1) in view of Iwamoto (JP 2011176076 A). Pertaining to claim 1, Sungkyunkwan University discloses, A degradable substrate for an electronic device, the degradable substrate comprising: a substrate base material which is a polymer material (see paragraph [0006] and [0073]). But, Sungkyunkwan University does not explicitly teach a degradable foam-generating material which is provided in a form of particles while being uniformly mixed with the substrate base material and generates foam by reacting with water. However, Iwamoto teaches a degradable foam-generating material which is provided in a form of particles while being uniformly mixed with the substrate base material and generates foam by reacting with water. (Iwamoto teaches wherein a wiring board includes an insulating material, a wiring formed on the insulating material, and a release layer formed between the insulating material and the wiring and containing metal carbonate or metal hydrogen carbonate, and the metal carbonates or metal bicarbonates are thermally decomposed and produce carbon dioxide (see chapter [0007]). Therefore, At the time of the invention, it would have been obvious before the effective filing date of the claimed invention to a person of ordinary skill in the art to provide a degradable foam-generating material which is provided in a form of particles while being uniformly mixed with the substrate base material and generates foam by reacting with water in the device of Sungkyunkwan University based on the teachings of Iwamoto in order to offers significant advantages in environmental sustainability, processing efficiency, and functional customization. Pertaining to claim 2, Sungkyunkwan University discloses, wherein the substrate base material is one of gelatin, polyvinyl alcohol (PVA), (see paragraph [0018]). Pertaining to claim 6, Sungkyunkwan University discloses all claimed limitations except, wherein the degradable foam- generating material has a molar ratio of the organic acid and the hydrogen carbonate in a range of 1:1 to 1:3. However, it would have been obvious to one having ordinary skill in the art at the time the invention was made to make the degradable foam- generating material has a molar ratio of the organic acid and the hydrogen carbonate in a range of 1:1 to 1:3, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable range involves only routine skill in the art. In re Aller, 105 USPQ 233. Pertaining to claim 7, Sungkyunkwan University discloses all claimed limitations except, wherein the substrate base material and the degradable foam-generating material have a weight ratio in a range of 4:1 to 1:2. However, it would have been obvious to one having ordinary skill in the art at the time the invention was made to make the substrate base material and the degradable foam-generating material have a weight ratio in a range of 4:1 to 1:2, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable range involves only routine skill in the art.

Pertaining to claim 3, Sungkyunkwan University discloses all claimed limitation except, wherein the degradable foam-generating material is formed of organic acid and hydrogen carbonate. However, Okada teaches wherein the degradable foam-generating material is formed of organic acid and hydrogen carbonate (claim 3). Therefore, At the time of the invention, it would have been obvious before the effective filing date of the claimed invention to a person of ordinary skill in the art to provide the degradable foam- generating material is formed of organic acid and hydrogen carbonate in the device of Sungkyunkwan University based on the teachings of Okada in order to offer significant advantages in environmental sustainability, safety, and production efficiency compared to traditional petroleum-based foams. Pertaining to claim 4, Sungkyunkwan University as modified by Okada further discloses, wherein the organic acid is one of citric acid, malic acid, succinic acid, malonic acid, tartaric acid, and acetic acid, or a mixture thereof, (see paragraph [0018 of Okada]). Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over Sungkyunkwan University (KR 10-2325518 B1) in view of Iwamoto (JP 2011176076 A) as applied to claim 3 above, and further in view of Okada (JP 2019183008 A) and Han et al.
