Office Action

§102 §103 §112
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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 7/27/2026 has been entered. Claim Objections Claims 4-5 are objected to because of the following informalities: (i) since claim 1 recites “a second part that extends from the first part in the first direction”, the recitation in claim 4 of “the second part of the at least one arm extends in the first direction” is objected to for failing to further limiting. 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. Claims 10-12 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 10: since claim 1 recites the at least one arm including a first part disposed on the first surface of the first plate or the second surface of the second plate, the recitation in claim 10 of the at least one arm includes “a first arm provided on the first surface of the first plate and a second arm provided on the second surface of the second plate” renders the claim indefinite for failing to clearly define the metes and bounds of the claimed invention, since it is not clear whether the first and second arms are the same or different from the first and second parts of claim 1. For the purpose of this examination, the claim will be examined as best understood or so far as definite. Claim 11: since claim 1 recites the at least one arm including a second part that extends from the first part in the first direction, the recitation in claim 11 of “a first shoulder bent from the first arm and a second shoulder bent from the second arm” renders the claim indefinite for failing to clearly define the metes and bounds of the claimed invention, since it is not clear whether the first and second shoulders are the same or different from the second part of claim 1. For the purpose of this examination, the claim will be examined as best understood or so far as definite. Claim 12 is rejected as being dependent on, and failing to cure the deficiencies of, a rejected claim. 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 text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.

Claim Rejections - 35 USC § 103 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 text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Jung ‘923 in view of Jung ‘088. Jung ‘923 discloses all the elements as discussed above including the limitations in claim 17 of wherein each of the first plate and the second plate is made of a metal material ([0088]). The difference being that Jung ‘923 fails to clearly disclose the limitations in claim 17 of wherein the cover adiabatic material is made of a non-metal material. However, Jung ‘088 discloses a vacuum adiabatic body comprising: a first plate 10; a second plate 35,70; a vacuum space 50 provided between the first plate 10 and the second plate 35,70; and a cover assembly comprising a first cover provided on the first plate and a second cover provided on the second plate, a cover adiabatic material 90 disposed at edges of the first and second plates, wherein each of the first plate and the second plate is made of a metal material ([0088]), and wherein the cover adiabatic material is made of a non-metal material ([80], “foaming urethane or Styrofoam”). Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention, in view of Jung ‘088, to modify Jung ‘923 to include the limitations in claim 17 of wherein the cover adiabatic material is made of a non-metal material with a reasonable expectation of success in order to increase the overall versatility of the vacuum adiabatic body. Response to Arguments Applicant's arguments filed 7/27/2026 have been fully considered but they are not persuasive. In response to applicant’s arguments on pages 12-13 regarding Fig. 11 of Jung, the examiner respectfully take the position that, as stated in the above rejection to claim 1 in paragraph #12, the conductive resistance adiabatic material 91 meets the limitations in claim 1 of “at least one arm 91 including a first part disposed on the first surface of the first plate 10 or the second surface of the second plate 35,70, and a second part that extends from the first part in the first direction and is disposed between an end of at least one of the first plate 10 or the second plate 35,70 and the cover adiabatic material 90”. Applicant’s arguments with respect to Okazaki, Allard, and Yoo have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Applicant’s arguments with respect to claim(s) 13 in view of Jung, Okazaki, Allard, and Yoo have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. In response to applicant’s arguments on pages 17-18 regarding Fig. 11 of Jung, the examiner respectfully take the position that, as stated in the above rejection to claim 18 in paragraph #12, the conductive resistance adiabatic material 91 meets the limitations in claim 18 of “a cover adiabatic material 90 disposed at edges of the first and second arms, wherein the cover adiabatic material 90 includes a portion that forms an edge of the vacuum adiabatic body and is exposed to an outside of the vacuum adiabatic body”.
