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 amendment filed on 01/30/2026 has been entered. Response to Arguments Applicant’s arguments with respect to at least independent claim 21 have been considered, but are not persuasive. The new ground of rejection cites Takagi US 2020/0319387 as teaching the amended claim limitations in claim 21. Claim Objections Claims 31 and 38 objected to because of the following informalities: Claim 31, lines 5-6, the phase “a transmitted light” should be “a first transmitted light” and the phase “a transmission spectrum” should be “a first transmission spectrum”; and Claim 38, the claim limitations “a transmitted light incident on the reference light absorber at an incident angle of 0 degree has a third transmission spectrum, the third transmission spectrum has a wavelength (e) at which a transmittance is 50% in a wavelength range of 350 nm to 480 nm” should be “a second transmitted light incident on the reference light absorber at an incident angle of 0 degree has a second transmission spectrum, the second transmission spectrum has a wavelength (e) at which a transmittance is 50% in a wavelength range of 350 nm to 480 nm” because a second transmitted light and the second transmission spectrum are not cited in claims 31 and 36. Appropriate correction is required. 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 (i.e., changing from AIA to pre-AIA ) 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. Claim(s) 21-22, 25-27 and 30-35 is/are rejected under 35 U.S.C. 103 as being unpatentable over Shiono US 2022/0179141 in view of Takagi US 2020/0319387. Regarding claim 21, Shiono discloses a light absorber (11), in at least figs.1, 4 and 5, comprising a resin and a light absorbent dispersed in the resin (see table 9), wherein a first transmitted light incident on the light absorber at an incident angle of 0 degree has a first transmission spectrum (para.284 and 260), the first transmission spectrum satisfies the following requirements (I), (II), (III), and (IV): (I) an average transmittance of 78% or more across a wavelength range of 480 nm to 580 nm (see figs.4 and 5); (II) a maximum transmittance of 1% or less across a wavelength range of 350 nm to 380 nm (see figs.4 and 5); (III) a maximum transmittance of 3% or less across a wavelength range of 800 nm to 1100 nm (see figs.4 and 5); and (IV) a transmittance of 10% or less at a wavelength of 400 nm (see figs.4 and 5), and the first transmission spectrum further has a wavelength (A) at which a transmittance is 50% in a wavelength range of 680 nm to 760 nm (see figs.4 and 5). Shiono does not explicitly disclose the maximum transmittance of 3% or less across the wavelength range of 800 nm to 1200 nm. Takagi discloses a light absorber, in at least figs.1A-4E and 14A-14B, the maximum transmittance of 3% or less across the wavelength range of 800 nm to 1200 nm (see figures.14A-14B and table 36 and para.222) for the purpose of forming a light absorber (para.229). Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the maximum transmittance of 3% or less across the wavelength range of 800 nm to 1200 nm as taught by Takagi in the light absorber of Shiono for the purpose of forming a light absorber. Regarding claim 22, Shiono discloses the first transmission spectrum further has a wavelength (B) at which a transmittance is 50% in a wavelength range of 405 nm to 480 nm (see figs.4 and 5). Regarding claim 25, Shiono discloses the transmission spectrum satisfies the following requirements (VIII), (IX), and (X): (VIII) a ratio of a transmittance at a wavelength of 550 nm to a transmittance at a wavelength of 400 nm is 8 or more (see figs.4 and 5); (IX) a ratio of the transmittance at a wavelength of 550 nm to a transmittance at a wavelength of 800 nm is 8 or more (see figs.4 and 5); and (X) a ratio of a transmittance at a wavelength of 680 nm to the transmittance at a wavelength of 800 nm is 8 or more (see figs.4 and 5). Regarding claim 26, Shiono discloses a first reflected light incident on the light absorber at an incident angle of 0 degree has a first reflectance spectrum, and the first reflectance spectrum has a maximum reflectance of 20% or less across a wavelength range of 800 nm to 1000 nm (see figs.4 and 5). Regarding claim 27, Shiono discloses a second transmitted light incident on the light absorber at an incident angle of 35 degree has a second transmission spectrum, the second transmission spectrum has a wavelength (C) at which a transmittance is 50% in a wavelength range of 350 nm to 480 nm and a wavelength (D) at which a transmittance is 50% in a wavelength range of 600 nm to 800 nm, a first absolute value of a difference between the wavelength (C) and the wavelength (B) is 5 nm or less (para.208 and 220, the result of incident angle of 35 degree is similar to the result of an incident angle of 30 degree), and a second absolute value of a difference between the wavelength (D) and the wavelength (A) is 10 nm or less (para.206 and 218, the result of incident angle of 35 degree is similar to the result of an incident angle of 30 degree). Regarding claim 30, Shiono discloses an article (12) with a light absorber, comprising: an article (12); and the light absorber according to claim 21 (see rejection of claim 21 above), provided on at least a portion of a surface of the article (see figs.1-3). Regarding claim 31, Shiono discloses a light-absorbing composition (11), in at least figs.1, 4 and 5, comprising: a resin and a light absorbent (see table 9), wherein the light-absorbing composition is capable of being cured to form a light absorber (see table 9), a first transmitted light incident on the light absorber at an incident angle of 0° has a first transmission spectrum (para.284 and 260), the first transmission spectrum has the following requirements (i), (ii), (iii), and (iv): (i) an average transmittance of 78% or more across a wavelength range of 480 nm to 580 nm (see figs.4 and 5); (ii) a maximum transmittance of 1% or less across a wavelength range of 350 nm to 380 nm (see figs.4 and 5); (iii) a maximum transmittance of 3% or less across a wavelength range of 800 nm to 1100 nm (see figs.4 and 5); and (iv) a transmittance of 10% or less at a wavelength of 400 nm (see figs.4 and 5), and the first transmission spectrum further has a wavelength (a) at which a transmittance is 50% in a wavelength range of 680 nm to 760 nm (see figs.4 and 5). Shiono does not explicitly disclose the maximum transmittance of 3% or less across the wavelength range of 800 nm to 1200 nm. Takagi discloses a light-absorbing composition, in at least figs.1A-4E and 14A-14B, the maximum transmittance of 3% or less across the wavelength range of 800 nm to 1200 nm (see figures.14A-14B and table 36 and para.222) for the purpose of forming a light absorber (para.229). Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the maximum transmittance of 3% or less across the wavelength range of 800 nm to 1200 nm as taught by Takagi in the light-absorbing composition of Shiono for the purpose of forming a light absorber. Regarding claim 32, Shiono discloses the first transmission spectrum further has a wavelength (b) at which a transmittance is 50% in a wavelength range of 405 nm to 480 nm (see figs.4 and 5). Regarding claim 33, Shiono discloses the transmission spectrum satisfies the following requirements (VIII), (IX), and (X): (VIII) a ratio of a transmittance at a wavelength of 550 nm to a transmittance at a wavelength of 400 nm is 8 or more (see figs.4 and 5); (IX) a ratio of the transmittance at a wavelength of 550 nm to a transmittance at a wavelength of 800 nm is 8 or more (see figs.4 and 5); and (X) a ratio of a transmittance at a wavelength of 680 nm to the transmittance at a wavelength of 800 nm is 8 or more (see figs.4 and 5). Regarding claim 34, Shiono discloses a first reflected light incident on the light absorber at an incident angle of 0 degree has a first reflectance spectrum, and the first reflectance spectrum has a maximum reflectance of 20% or less across a wavelength range of 800 nm to 1000 nm (see figs.4 and 5). Regarding claim 35, Shiono discloses a second transmitted light incident on the light absorber at an incident angle of 35 degree has a second transmission spectrum, the second transmission spectrum has a wavelength (c) at which a transmittance is 50% in a wavelength range of 350 nm to 480 nm and a wavelength (d) at which a transmittance is 50% in a wavelength range of 600 nm to 800 nm, a first absolute value of a difference between the wavelength (c) and the wavelength (b) is 5 nm or less (para.208 and 220, the result of incident angle of 35 degree is similar to the result of an incident angle of 30 degree), and a second absolute value of a difference between the wavelength (d) and the wavelength (a) is 10nm or less (para.206 and 218, the result of incident angle of 35 degree is similar to the result of an incident angle of 30 degree). Claim(s) 28 and 29 is/are rejected under 35 U.S.C. 103 as being unpatentable over Shiono US 2022/0179141 in view of Takagi US 2020/0319387 as applied to claim 21 above, and further in view of Hayashi US 2021/0024754. Regarding claims 28 and 29, Shiono discloses an ultraviolet absorbent (para.70 and 147-148) including a compound that has a hydroxy group and a carbonyl group in a molecule (para.149 discloses at least merocyanine dyes, naphthalimide dyes, naphthalic acid dyes including a compound that has a hydroxy group and a carbonyl group in a molecule). Shiono in view of Takagi does not explicitly disclose a light absorber further comprising at least one metal component other than copper and phosphorus; and the metal component other than copper is at least one selected from the group consisting of Al, Ti, Zr, Zn, Sn, and Fe. Hayashi discloses a light-absorber, a light absorber further comprising at least one metal component other than copper and phosphorus (para.4, 25 and 42); and the metal component other than copper is at least one selected from the group consisting of Al, Ti, Zr, Zn, Sn, and Fe (para.4, 25 and 42) for the purpose of improving dispersion stability of the light absorbing composition, suppressing aggregation of the light absorber, reducing haze of the thin film formed from the light absorbing composition, and achieving improvement in visible light transmittance (para.25). Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have a light absorber further comprising at least one metal component other than copper and phosphorus; and the metal component other than copper is at least one selected from the group consisting of Al, Ti, Zr, Zn, Sn, and Fe as taught by Hayashi in the light-absorber of Shiono in view of Takagi for the purpose of improving dispersion stability of the light absorbing composition, suppressing aggregation of the light absorber, reducing haze of the thin film formed from the light absorbing composition, and achieving improvement in visible light transmittance. Claim(s) 36-38 is/are rejected under 35 U.S.C. 103 as being unpatentable over Shiono US 2022/0179141 in view of Takagi US 2020/0319387 as applied to claim 31 above, and further in view of Hayashi US 2021/0024754. Regarding claim 36, Shiono discloses further comprising: an ultraviolet absorbent capable of absorbing at least a portion of ultraviolet (para.70 and 147-148). Takagi discloses the light absorbent includes a light-absorbing compound that includes a phosphonic acid and a copper component (para.125) for the purpose of forming a light-absorbing layer (para.125,127 and 129). The reason for combining is the same as claim 31. Shiono in view of Takagi does not explicitly disclose at least one selected from the group consisting of an alkoxide including a metal component other than copper and a hydrolysate of the alkoxide. Hayashi discloses a light-absorbing composition, at least one selected from the group consisting of an alkoxide including a metal component other than copper and a hydrolysate of the alkoxide (para.4, 25 and 42) for the purpose of improving dispersion stability of the light absorbing composition, suppressing aggregation of the light absorber, reducing haze of the thin film formed from the light absorbing composition, and achieving improvement in visible light transmittance (para.25). Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have at least one selected from the group consisting of an alkoxide including a metal component other than copper and a hydrolysate of the alkoxide as taught by Hayashi in the light-absorbing composition of Shiono in view of Takagi for the purpose of improving dispersion stability of the light absorbing composition, suppressing aggregation of the light absorber, reducing haze of the thin film formed from the light absorbing composition, and achieving improvement in visible light transmittance. Regarding claim 37, Shiono discloses the ultraviolet absorbent includes a compound that has a hydroxy group and a carbonyl group in a molecule (para.149 discloses at least merocyanine dyes, naphthalimide dyes, naphthalic acid dyes including a compound that has a hydroxy group and a carbonyl group in a molecule). Regarding claim 38, Shiono discloses a composition that includes the ultraviolet absorbent and that does not include the alkoxide and the hydrolysate of the alkoxide is cured to form a reference light absorber (para.70 and 147-148), a second transmitted light incident on the reference light absorber at an incident angle of 0 degree has a second transmission spectrum (see figs.4 and 5), the second transmission spectrum has a wavelength (e) at which a transmittance is 50% in a wavelength range of 350 nm to 480 nm (see figs.4 and 5), and an absolute value of a difference between the wavelength (e) and the wavelength (b)(see figs.4 and 5). Shiono in view of Takagi and Hayashi does not explicitly the absolute value is 20 nm or more. However, one of ordinary skill in the art would have been led to the absolute value is 20 nm or more through routine experimentation and optimization, in re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). The Applicant has not disclosed that the range is for a particular unobvious purpose, produce an unexpected/significant result, or are otherwise critical, and it appears prima facie that the process would possess utility using another range. Indeed, it has been held that mere range limitations are prima facie obvious absent a disclosure that the limitations are for a particular unobvious purpose, produce an unexpected result, or are otherwise critical. Therefore, Accordingly, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have the absolute value is 20 nm or more in the light-absorbing composition of Shiono in view of Takagi and Hayashi for the purpose of improving dispersion stability of the light absorbing composition, suppressing aggregation of the light absorber, reducing haze of the thin film formed from the light absorbing composition, and achieving improvement in visible light transmittance (para.25 of Hayashi). Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Takagi US 2020/0319387 can be primary reference in view of Shiono US 2022/0179141 as well.
