Office Action

§102 §103 §112
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 . 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 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. Election/Restrictions Applicant's election with traverse of Group I, claims 25-30, 49-57 in the reply filed on 12/19/2025 is acknowledged. The traversal is on the grounds that a Restriction Requirement regarding related products, as in this application, requires that the related products meet the combination of all of the examiner's distinction elements (1), (2), and (3) and none of the examiner's distinction elements (1), (2), or (3) satisfy any one of the requirements for a Restriction under MPEP 806.05(j). This is found persuasive and the restriction requirement has been withdrawn. 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. Claim 69 is 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. Regarding claim 69, the phrase "such as" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). 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)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim 25-28, 49-53, 56-69 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Schiffmann et al. (US Patent Application No. 2014/0102024).

Regarding claim 69, Schiffmann et al. teach wherein a cross section of a given said stud comprises a closed profile (page 2, paragraph [0027]). 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. 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. Claims 29, 30, 54 and 55 are rejected under 35 U.S.C. 103 as being unpatentable over Schiffmann et al. (US Patent Application No. 2014/0102024) in view of Novak (US Patent Application No. 2003/0134103). Schiffmann et al. are relied upon as disclosed above. Regarding claims 29 and 30, Schiffmann et al. fail to teach wherein one or more mechanical keepers securing said foam blocks, in said foam block cluster, to teach other. However, Novak teaches a foam sheet (page 1, paragraph [0006]) comprising a mechanical keeper comprising threads (page 1, paragraph [0007], page 3, paragraph [0041]). It would have been obvious to a person of the ordinary skill in the art before the effective filing date of the claimed invention to use the mechanical fastener of Novak in the foam blocks of Schiffmann et al. in order to provide fastener retention that are cost effective to produce and relatively simple to manufacture (Novak, page 1, paragraphs [0006], [0007]). Regarding claim 54, Schiffmann et al. fail to teach wherein one or more said threads extending from said first foam block to opposing end foam block on an opposing of said foam block cluster. However, Novak teaches a foam sheet (page 1, paragraph [0006]) comprising a mechanical keeper comprising threads (page 1, paragraph [0007], page 3, paragraph [0041]). It would have been obvious to a person of the ordinary skill in the art before the effective filing date of the claimed invention to use the thread of Novak extending from said first foam block to an opposing end foam block on an opposing end of said foam block cluster of Schiffmann et al. in order to provide fastener retention that are cost effective to produce and relatively simple to manufacture (Novak, page 1, paragraphs [0006], [0007]). Regarding claim 55, Schiffmann et al. fail to teach wherein said one or more threads extending, under substantial tension, from said first foam block to an opposing end foam block. However, Novak teaches a foam sheet (page 1, paragraph [0006]) comprising a mechanical keeper comprising threads (page 1, paragraph [0007], page 3, paragraph [0041]). It would have been obvious to a person of the ordinary skill in the art before the effective filing date of the claimed invention to use the thread of Novak extending, under substantial tension, from said first foam block to an opposing end foam block of Schiffmann et al. in order to provide fastener retention that are cost effective to produce and relatively simple to manufacture (Novak, page 1, paragraphs [0006], [0007]).
