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 . Information Disclosure Statement The information disclosure statement (IDS) submitted on 07/14/2023, and 10/27/2025. The submission 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 1-20 are objected to because of the following informalities: In claim 1: The phrase “the the fastener belt” as cited in line 12, should be changed to -- the fastener belt--; The phrase “as as to adjust” as cited in line 13, should be changed to --configured to adjust--; and Appropriate correction is required. Claim Rejections - 35 USC § 103 The following is a quotation of AIA 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made. The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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 1, 7-8, 11, and 13-20 are rejected under 35 U.S.C. 103 as being unpatentable over Portney (US 5384916) in view of Murray et al. (US 4061898). Regarding claim 1, Portney discloses A hair cap (cap 1, figs.1-2), comprising: a cap body (cap crown 3, lower margin 9, figs.1-2) comprising a bottom part (lower margin 9, figs.1-2) and a side wall (side wall of cap crown 3, figs.1-2) connected with the bottom part (lower margin 9), the bottom part (lower margin 9) and the side wall (side wall of cap crown 3) forming a wearing chamber (chamber of cap 1, fig.1) and a wearing opening (bottom opening of cap 1, fig.1) communicating the wearing chamber (chamber of cap 1), the side wall (side wall of cap crown 3) comprising a first inner chamber (sweatband 7, figs.1-2) surrounding the wearing opening (bottom opening of cap 1), two first openings (openings 11, slot 27, figs.1-2) adjacent to each other and communicating two ends of the first inner chamber (sweatband 7) and a second inner chamber (chamber of cap crown 3, figs.1-2) surrounding the wearing chamber (chamber of cap 1); a fastener belt (strip 17, figs.1-2), a part (left end of trip 17) of the fastener belt (strip 17) located in the first inner chamber (sweatband 7) and the other part (right end of trip 17) of the fastener belt (strip 17) connected extending from the two first openings (openings 11, slot 27); and an adjusting element (hook fastener strip 29, figs.4,6) disposed on the fastener belt (strip 17), wherein the adjusting element (hook fastener strip 29) is able to slide along the fastener belt (strip 17) and to be fixed at two positions of the fastener belt (strip 17) adjacent to the two first openings (openings 11, slot 27), to adjust a length of the part of the fastener belt (strip 17) located in the first inner chamber (sweatband 7) and fasten the cap body (cap crown 3, lower margin 9) on a user's head.
