Priority Receipt is acknowledged of certified copies of papers submitted under 35 U.S.C. § 119(a)-(d), which papers have been placed of record in the file. Acknowledgment is made of applicant's claim for foreign priority based on an application filed in The Republic of Germany on November 09, 2022. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim 1 and 5-7 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by United States Patent Application No. US 2017/0181491 A1 Colt Miller, (herein after "Miller").

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.

Therefore, based on Trainor’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 Miller’s, respective neck strap to include having the strap buckle as doing so would provide a chin strap assembly that is adjustable for optimizing fit for the wearer. As this would be the simple substitution of one strap buckle for another with the reasonable expectation that one strap buckle would perform equally as well as another.
