Office Action

§103
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 . Response to Amendment The amendments filed with the written response received on June 06, 2026 have been considered and an action on the merits follows. As directed by the amendment, claims 1 and 5-7 have been amended and claim 2-4 and 9-14 have been canceled. Claims 15-18 are new. Accordingly, claims 1, 5-8, and 15-18 are pending in this application, with an action on the merits to follow. Response to Arguments Applicant’s arguments with respect to claims 1-14 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Claim Rejections - 35 USC § 103 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 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 1,5-7 and 15-18 are rejected under 35 U.S.C. § 103 as being unpatentable over United States Patent Application Publication No. US 2023/0012326 A1 to Christopher Dumph, (herein after "Dumph") in view of United States Patent Application Publication No. US 2017/0181491 A1 to Colt Miller et al., (herein after "Miller”). As to Claim 1, Dumph teaches a chin strap assembly (helmet retention harness100; Dumph ~ regarding a chin strap assembly) for helmets (helmet 120; Dumph), comprising: i) a first right main strap which can be fastened to the helmet (helmet 120; Dumph), via a first mounting eyelet to be secured (Figures 1-4; Dumph), ii) a second left main strap which can be fastened to the helmet via a second mounting eyelet to be secured (Figures 1-4; Dumph) and jij) a chin strap which connects both main straps (Figures 1-4 and Paragraph 0024; Dumph) (Figures 1-3 and Paragraph 0024; Dumph ~ regarding a chin strap), wherein the chin strap is fastened at each end to the respective main strap via a connection at the end (Figures 1-4; Dumph) (right temple strap 110b; Dumph ~ regarding a first right main strap)(Figures 1-3 and Paragraph 0024; Dumph ~ teaching being attachable at forward ends ~ regarding a connection at the ends), wherein at least one first strap clip is attached to the first right main strap as a release (Figures 1-3 and Paragraph 0027; Dumph ~ regarding a first strap clip is attached to the first right main strap as a release), wherein at least one second strap clip is attached to the second left main strap as a release (Figures 1-3 and Paragraph 0027; Dumph ~ regarding a second strap clip is attached to the second left main strap as a release), wherein the first right main strap has a cheek strap and a neck strap (Figures 1-3; Dumph ~ regarding a cheek strap)(Figures 1-3; Dumph ~ regarding a neck strap)(Figures 1-3; Dumph ~ regarding a first right main strap)(Figures 1-3; Dumph ~ regarding wherein the first right main strap has a cheek strap and a neck strap), wherein the second left main strap has a cheek strap and a neck strap wherein the second left main strap has a cheek strap and a neck strap (Figures 1-3 and Paragraph 0027; Dumph ~ regarding wherein the second left main strap has a cheek strap and a neck strap), and wherein for easier handling the straps when opening and closing at least one or both of: a) the respective neck strap has the strap clip to be independent from the respective cheek strap (Figures 1-3; Dumph ~ regarding wherein for easier handling the straps when opening and closing at least one or both of: a) the respective neck strap has the strap clip to be opened or closed independent from the respective cheek strap. Thereby teaching at least one of the respective neck strap has the strap clip to be opened.); b) the respective cheek strap has the strap clip to be opened or closed independent from the respective neck strap. Dumph fails to disclose a first strap clip being a quick release, a second strap clip being a quick release, a strap clip being opened or closed. Miller teaches mask coupling apparatus and discloses a strap clip (fastener 18; Miller) being a quick release (Figures 1-3 and Paragraphs 0005, 0007, 0017-0019; Miller ~ regarding being quick release), a strap clip (securing strap 50; Miller) being a quick release (Figures 1-3 and Paragraphs 0005, 0007, 0017-0019; Miller ~ regarding being quick release), a strap clip being opened or closed (Figures 1-3 and Paragraphs 0002, 0004, 0005, 0007, 0017-0019; Miller ~ regarding being quick release. It is well known that quick release clips/ buckles are capable of being opened or closed). Therefore, based on Miller’s teachings, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to have modified Dumph’s, first and second strap clip to include a first strap clip being a quick release, a second strap clip being a quick release, a strap clip being opened or closed, as doing so would provide for easy and quick coupling and adjustments and uncoupling in the field.

Thereby teaching at least one of the respective neck strap has the strap clip to be independent from the cheek strap.); and b) the cheek strap has the strap clip independent from the neck strap; and wherein the second left strap has at least one of: a) the neck strap has the strap clip independent from the cheek strap (Figures 1-4; Dumph ~ regarding wherein the second left strap has at least one of: a) the neck strap has the strap clip independent from the cheek strap); and b) the cheek strap has the strap clip independent from the neck strap (Figures 1-4; Dumph ~ regarding the cheek strap has the strap clip independent from the neck strap). Dumph fails to disclose a quick release, a quick release, the clip to be opened or closed, the clip to be opened or closed, the clip to be opened or closed, the clip to be opened or closed. Miller teaches mask coupling apparatus and discloses a strap clip (fastener 18; Miller) being a quick release (Figures 1-3 and Paragraphs 0005, 0007, 0017-0019; Miller ~ regarding being quick release), a strap clip (securing strap 50; Miller) being a quick release (Figures 1-3 and Paragraphs 0005, 0007, 0017-0019; Miller ~ regarding being quick release), a strap clip being opened or closed (Figures 1-3 and Paragraphs 0002, 0004, 0005, 0007, 0017-0019; Miller ~ regarding being quick release. It is well known that quick release clips/ buckles are capable of being opened or closed) a strap clip being opened or closed (Figures 1-3 and Paragraphs 0002, 0004, 0005, 0007, 0017-0019; Miller ~ regarding being quick release. It is well known that quick release clips/ buckles are capable of being opened or closed) a strap clip being opened or closed (Figures 1-3 and Paragraphs 0002, 0004, 0005, 0007, 0017-0019; Miller ~ regarding being quick release.

It is well known that quick release clips/ buckles are capable of being opened or closed). Therefore, based on Miller’s teachings, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to have modified Dumph’s, first right main strap and second left main strap to include both being a quick release, as doing so would provide for easy and quick coupling and adjustments and uncoupling in the field. Therefore, based on Miller’s teachings, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to have modified Dumph’s, the strap clip, the strap clip, the strap clip, the strap clip to include to be opened or closed independent, to be opened or closed independent, to be opened or closed independent, to be opened or closed independent, as doing so would provide for easy and quick coupling and adjustments and uncoupling in the field.
