Office Action

§112
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 . Claim Objections Claims 1, 2, 5-7, 9, 11 and 12-16 objected to because of the following informalities: Claim 1, line 21, the phase (√(a*2+b*2) should be (√(a*2+b*2)) and line 16, the phase “the hexagonality” should be “the mean hexagonality”; Claim 5, line 2, the phase “color a gamut level” should be “a color gamut level”; Claims 2, 6, 9 and 14, the phase “the article” should be “the display article” for the purpose of consistency; Claim 7, the phase “the coated article” should be “the display article” for the purpose of consistency; Claim 11, lines 1 and 2, the claim limitation “the plurality of structural features further comprises first portion at a first average height and a second portion at a second average height” should be “the plurality of structural features further comprises a first portion has a first average height and a second portion has a second average height”; Claim 12, lines 1-3, the claim limitations “the first portion comprises a fill fraction that is from 30% to 70% of the diffractive surface region, wherein the second portion comprises a second fill fraction that is 100% minus the fill fraction” should be “the first portion comprises a first fill fraction that is from 30% to 70% of the diffractive surface region, wherein the second portion comprises a second fill fraction that is 100% minus the first fill fraction”; Claim 13, line 1, the phase “the fill fraction” should be “the first fill fraction”; and Claims 14-16 should be cancelled due to claim interpretation of 112 2nd below. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-20 rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding claim 1, the claim limitations, “A display article, comprising: a substrate comprising a thickness and a primary surface; one of a diffractive surface region and a roughened surface region defined by the primary surface; and an antireflective coating disposed on the textured surface region or the diffractive surface region defined by the primary surface of the substrate, wherein the substrate exhibits a sparkle of less than 5%, as measured by pixel power deviation (PPD140) at an incident angle of 0° from normal, and a transmittance haze of less than 40% from an incident angle of 0° from normal, wherein: the antireflective coating comprises a plurality of alternating high refractive index and low refractive index layers, each of the low refractive index layers comprises a refractive index of less than or equal to about 1.8, and each of the high refractive index layers comprises a refractive index of greater than 1.8, if the primary surface defines the diffractive surface region, the diffractive surface region exhibits a mean hexagonality (H) in a range from 0.36 to 0.8, the hexagonality for each structural feature of the diffractive surface region being computed as PNG media_image1.png 84 230 media_image1.png Greyscale where ak represents the angles of the six nearest structural features to one of the structural features with respect to an arbitrary axis, and the display article exhibits a reflected color (√(a*2+b*2) from the antireflective coating that is less than 5 for all incident angles from 0° to 60° as measured with a D65 illuminant” are considered to be indefinite. The claim limitation “if the primary surface defines the diffractive surface region" make it unclear whether claim 1 still need the primary surface defines the roughened surface region or if the primary surface defines the roughened surface region does last two paragraph of claim 1 still having patentable weight. Therefore, it is indefinite. For the purpose of examination, the examiner will interpret the above limitation as - - “A display article, comprising: a substrate comprising a thickness and a primary surface; 140) at an incident angle of 0° from normal, and a transmittance haze of less than 40% from an incident angle of 0° from normal, wherein: the antireflective coating comprises a plurality of alternating high refractive index and low refractive index layers, each of the low refractive index layers comprises a refractive index of less than or equal to about 1.8, and each of the high refractive index layers comprises a refractive index of greater than 1.8, mean hexagonality for each structural feature of the diffractive surface region being computed as PNG media_image1.png 84 230 media_image1.png Greyscale where ak represents the angles of the six nearest structural features to one of the structural features with respect to an arbitrary axis, and the display article exhibits a reflected color (√(a*2+b*2)) from the antireflective coating that is less than 5 for all incident angles from 0° to 60° as measured with a D65 illuminant” - -. Also, dependent Claims 2-20 are rejected by virtue of their dependency. Allowable Subject Matter Claims 1-13 and 17-20 would be allowable if rewritten or amended in independent form including all of the limitations of the base claim and any intervening claims to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action. The following is an examiner’s statement of reasons for allowance: Regarding claim 1, the prior art of record, taken alone or in combination, fails to teach or disclose, in light of the specification, the claim limitation of claim 1. In addition, Gregorski US 2019/0219739, Koch US 2020/0408954 and Gu US 2020/0379143 taken along or in combination, at least fails to disclose or suggest a display article having a substrate comprising a thickness and a primary surface; 140) at an incident angle of 0° from normal, and a transmittance haze of less than 40% from an incident angle of 0° from normal, wherein: the antireflective coating comprises a plurality of alternating high refractive index and low refractive index layers, each of the low refractive index layers comprises a refractive index of less than or equal to about 1.8, and each of the high refractive index layers comprises a refractive index of greater than 1.8, mean hexagonality for each structural feature of the diffractive surface region being computed as PNG media_image1.png 84 230 media_image1.png Greyscale where ak represents the angles of the six nearest structural features to one of the structural features with respect to an arbitrary axis, and the display article exhibits a reflected color (√(a*2+b*2)) from the antireflective coating that is less than 5 for all incident angles from 0° to 60° as measured with a D65 illuminant. Claims 2-13 and 17-20 are depended on claim 1 so they are allowable for the same reason.
