Office Action

§102 §112
DETAILED ACTION Claims 1-17 are pending. 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 . 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 2-8, 12, 15 and 17 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 pre-AIA the applicant regards as the invention. Claim 2 recites “protruding shape” and “recessed shape” (twice each). It is unclear what is considered a “protruding shape”. The examiner is interpreting this as a protrusion. It is unclear what is considered a “recessed shape”. The examiner is interpreting this as a recess. Claim 5 recites “in this order” however it is unclear what “this order” refers to. The examiner is interpreting this to refer to first contacting the protruding portion and then contacting the presser foot. Claim 5 recites “the engagement between the fitting portion and the fitted portion is released” however now such engagement is recited to have occurred in the first place. It is thus unclear how it can be released. Claim 6 recites that there is an eaves portion at the end of the insertion opening. An opening is a lack of something, and thus it is unclear what is meant by this phrase because it is unclear how the opening has an “end” and what would be considered an end of an opening. Due to this confusion, the examiner is interpreting “opening” as not requiring a through-hole, but rather, a depression, groove, blind-hole would qualify as an opening. Claim 8 recites the fitting portion has a protruding shape, however this is already recited in claim 2. It is unclear if this is a different protruding shape than that recited in claim 2. Claim 8 recites “a recessed shape” (twice) however this is already recited in claim 2. It is unclear if this is a different recessed shape than that recited in claim 2. Claim 8 also has the same issues as claim 2 with respect to protruding and recessed shape. Claim 12 recites “protruding shape” and “recessed shape” (twice each). It is unclear what is considered a “protruding shape”. The examiner is interpreting this as a protrusion. It is unclear what is considered a “recessed shape”. The examiner is interpreting this as a recess. Claim 15 recites “protruding shape” and “recessed shape” (twice each). It is unclear what is considered a “protruding shape”. The examiner is interpreting this as a protrusion. It is unclear what is considered a “recessed shape”. The examiner is interpreting this as a recess. Claim 17 recites “protruding shape” and “recessed shape” (twice each). It is unclear what is considered a “protruding shape”. The examiner is interpreting this as a protrusion. It is unclear what is considered a “recessed shape”. The examiner is interpreting this as a recess. The dependent claims inherit(s) the deficiency by nature of dependency. 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 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 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. Claim(s) 1-3, 6, 9-12, and 14-17 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Takei (US 20230064230).
