DETAILED ACTION Election/Restrictions Claims 11 and 17 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected species, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 11/14/2025. Drawings The drawings filed on 08/09/2023 are acceptable. Claim Objections Claim 8 is objected to because of the following informalities: “ the matching mechanism protrusion ” should read “ the l atching mechanism protrusion ”. 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. Claim s 13 and 19 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. With respect to Claim 13, the claim is rendered unclear because of the phrase “ wherein the geometric profile is substantially D-shape d”. It is not clear if the geometric profile refers to the geometric profile of the latching mechanism receiving cutaway , the latching mechanism receiving recess , the l atching mechanism protrusion , or the latching mechanism receiving cutaway . For the purpose of examination, “ wherein the geometric profile is substantially D-shape d” is interpreted as “ wherein the geometric profile of the latching mechanism receiving cutaway is substantially D-shape d ”. With respect to Claim 1 9 , the claim is rendered unclear because of the phrase “ wherein the shape is substantially D-shaped ”. It is not clear if the shape refers to the geometric profile of the latching mechanism receiving cutaway or the latching mechanism receiving recess . For the purpose of examination, “ wherein the shape is substantially D-shaped ” is interpreted as “ wherein the shape of the latching mechanism receiving cutaway is substantially D-shape d ”.
