Applicant’s submission, filed 15 January 2026, has been entered and acknowledged by the examiner. Applicant's arguments filed 15 January 2026 with respect to the rejections of claims 10, 11, 23, 24 under 35 USC 103 have been fully considered but they are not persuasive. Applicant’s remaining arguments with respect to the rejections of the claims have been considered but are moot in view of the new grounds of rejection. Claim Rejections - 35 USC § 102 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. Claims 1-9, 12-22, 25-28 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Amin et al. (USPN 2015/0322270). With regard to claim 1, Amin et al. disclose a transparent article, comprising: a substrate (110) comprising a first primary surface (112) and a second primary surface (114), the primary surfaces opposing one another; and an optical film structure (120) defining an outer surface, the optical film structure disposed on the first primary surface (see fig 1), wherein the optical film structure comprises a scratch-resistant layer (paragraph 132) and a plurality of alternating high RI (130A) and low RI layers (130B), wherein the optical film structure further comprises an outer structure (lower grouping) and an inner structure (upper grouping), the scratch-resistant layer (see paragraph 132) disposed between the outer and inner structures (e.g. table 9 sialon 350nm layer), wherein one or both of: (i) the outer structure comprises at least one medium RI layer (130c) in contact with one or both of: (a) the scratch-resistant layer and (b) one of the high RI layers (see figs. 3,4); and (ii) a sum of the physical thicknesses of all of the low RI layers in the outer structure is less than about 200 nm (see paragraph 125), and further wherein the at least one medium RI layer comprises a refractive index from 1.55 to 1.80 (see paragraph 122), each of the high RI layers comprises a refractive index of greater than 1.80 (See paragraph 122), and each of the low RI layers comprises a refractive index of less than 1.55 (see paragraph 122).

Claim Rejections - 35 USC § 103 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 10, 11, 23, 24 are rejected under 35 U.S.C. 103 as being unpatentable over Amin et al. (as above). With regard to claims 10,11, 23, 24, Amin et al. disclose the transparent article of claims 1,13, while Amin et al. do not explicitly disclose a textured or diffractive surface region, such regions were well known to and widely used by those of ordinary skill in the art at the time of the invention and would have been obvious to the same to incorporate into the article of Amin et al. in order to reduce reflectivity. Response to Arguments While the applicant argues, with respect to the rejections of claims 10, 11, 23, 24, that the examiner provided no reasoning to combine the features with the prior art article, the examiner asserts that reasoning, i.e., to reduce reflectivity, the purpose of the prior art reference, was provided in the rejection. Additionally, while the applicant argues that the features are utilized in the instant application for antiglare capability rather than reflectivity reduction, the presence of an alternative possible motivation for combination does not obviate the motivation asserted by the examiner.
