Office Action

§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 . DETAILED ACTION Status of the Claims Claims 1-11 are pending in the current application. 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 1-11 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. Claims 1 and 10 repeatedly recites the limitation “the bottom plate”, “the insulating plate” (claim 10), “the first insulating plate” (claim 1), “the second insulating plate” (claim 1) and “the strip shaped hole” after respective limitations requiring a plurality of bottom plates, a plurality of first insulating plates, a plurality of second insulating plates and a plurality of strip shaped holes. There is insufficient antecedent basis for these limitations in the claim. It is unclear as to whether the quoted limitations are directed towards each of the plurality of plates and/or holes or can be satisfied by a single one of the plurality of the referenced plates and/or holes. The claim is therefore indefinite. Claims 2-9 and 11 are rejected for their dependence upon claim 1. Allowable Subject Matter Assuming the instant rejections under 35 USC 112 are overcome, the instant claims would stand in condition for allowance. Prior art exists disclosing knowledge in the art of various frame configurations including: CN 109234708 (as cited in IDS): disclosing a frame structure with base and ‘interlocking’ second layer (figures 6-8). US 20220081774: disclosing a frame structure with interlocking components on a frame base, containing holes in a vertical direction (figure 4 and 6). US 20210180186: disclosing frame and base frame structure with holes for containing wires (figures 14-15). US 20110174217: disclosing multilayer frame with multiple segments on each layer (figure 4). However, none of the prior art contains the requisite frame base and insulating frame with the requisite extension structures, the two in contact and containing a plurality of strip shaped holes between an inside and outside of the frame, as required by the instant claims, without impermissible hindsight combination.
