Office Action

§102 §103 §DOUBLEPATENT
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 . Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer.

Claim Rejections - 35 USC § 102 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 – 3, 5 – 7, and 8 – 19 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Woong et al. (KR 10-2019-0018835). Woong et al. discloses a vacuum adiabatic body (Figures; Abstract) comprising: a first plate (Figure 8, #10); a second plate including a portion separated from the first plate in a first direction to define a vacuum space between the first plate and the second plate (Figure 8, #20); a support provided between the first plate and the second plate (Figure 8, #30), wherein the support includes a plurality of distribution structures that are spaced apart from each other (Figures 13 and 15) as in claim 1.

As in claim 19, at least one of the plurality of through-holes is defined by a pair of first extensions extending in a second direction and a pair of second extensions extending in a third direction that intersects the second direction (Figures 13 and 15). 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 4, 8, and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Woong et al. (KR 10-2019-0018835). Woong et al. discloses a vacuum adiabatic body (Figures; Abstract) comprising: a first plate (Figure 8, #10); a second plate including a portion separated from the first plate in a first direction to define a vacuum space between the first plate and the second plate (Figure 8, #20); a support provided between the first plate and the second plate (Figure 8, #30), wherein the support includes a plurality of distribution structures that are spaced apart from each other (Figures 13 and 15). However, Woong et al. fail to disclose an adjacent pair of the distribution structures are separated by 5 or more and 8 or less through-holes, the number of the outer distribution structures is greater than the number of the inner distribution structures, or the distance between the two adjacent outer distribution structures is greater than the distance between the two adjacent inner distribution structures, and the support includes a first support plate, and a second support plate coupled to the first support plate, wherein a first plurality of distribution structures of the first support plate and a second plurality of distribution structures of the second support plate are disposed at a misaligned position. With regard to the limitations of “an adjacent pair of the distribution structures are separated by 5 or more and 8 or less through-holes, the number of the outer distribution structures is greater than the number of the inner distribution structures, or the distance between the two adjacent outer distribution structures is greater than the distance between the two adjacent inner distribution structures, and the support includes a first support plate, and a second support plate coupled to the first support plate, wherein a first plurality of distribution structures of the first support plate and a second plurality of distribution structures of the second support plate are disposed at a misaligned position”, It would have been an obvious matter of design choice to change the distribution structures, since such a modification would have involved a mere change in the size of a component. A change in size or shape is generally recognized as being within the level of ordinary skill in the art, absent unexpected results. MPEP 2144.04.
