Information Disclosure Statement The information disclosure statement (IDS) submitted on 6/11/2024 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Claim Objections Claims 6, 8, and 10 are objected to because of the following informalities: In Claim 6 Line 3, “the rigidity” should be revised to “a rigidity” to ensure clarity in the claim. In Claim 8 Line 2, “faces the rigid reinforcement portion is configured” should be revised to “faces the rigid reinforcement portion and is configured” to ensure proper grammar. In Claim 10 Line 7, “the position” should be revised to “a position” to ensure clarity in the claim. Appropriate correction is required. 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 (i.e., changing from AIA to pre-AIA ) 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.
