Office Action

§102 §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 11/15/2025 has been entered. Response to Arguments Applicant’s arguments with respect to at least independent claim 1 have been considered but are moot because the arguments do not apply to any of the references being used in the current rejection because the examiner changes citation of Ishii US 2022/0105710. In addition, the currently amended claim 2 belongs to the nonelected Species B (figs.8 and 9), so that claim 2 should be withdrawn as claims 14-20. 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 (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 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(s) 1, 4, 7 and 10-13 is/are rejected under 35 U.S.C. 102(a)(1) and 35 U.S.C. 102(a)(2) as being anticipated by Ishii US 2022/0105710. Regarding claim 1, Ishii discloses an apparatus having a multi-layer structure for providing a dimmable window operation, in at least figs.1-6F, 9-11 and 14-20 and wherein the apparatus comprises: a first rigid substrate (11, or 50); a second rigid substrate (12, or 12 with 14) coupled to the first rigid substrate at a perimeter region of the multi-layer structure, to maintain a separation between the first rigid substrate and the second rigid substrate (see at least figs.2 and 10); and a liquid crystal (LC) film (23, or 20) positioned within the separation between the first rigid substrate and the second rigid substrate (see at least figs.2 and 10), wherein the LC film is coupled to either the first rigid substrate or the second rigid substrate at an inner region of the multi-layer structure to define a gap (G) between the LC film and another one of the first rigid substrate and the second rigid substrate (see at least figs.2 and 10), and wherein the gap filled with argon gas or an air mixture including nitrogen gas and oxygen gas, to provide thermal isolation (para.81 discloses the gap layer G made up of an air layer to improve heat insulation property of the apparatus, and it’s inherent that the air layer contain at least nitrogen gas and oxygen gas). Regarding claim 4, Ishii discloses the gap is characterized by a separation distance ranges from 0.1 millimeter to 4 millimeters (para.81). Regarding claim 7, Ishii discloses comprising a perimeter support member (17) positioned at the perimeter region of the multi-layer structure and configured to couple the first rigid substrate to the second rigid substrate (see at least figs.2 and 10); wherein the first rigid substrate, the second rigid substrate, and the perimeter support member are configured to maintain airtightness of the separation between the first rigid substrate and the second rigid substrate (see at least figs.2 and 10). Regarding claim 10, Ishii discloses the first rigid substrate comprises a tempered glass layer (para.62 discloses it’s a glass layer with high heat resistance and high flaw resistance). Regarding claim 11, Ishii discloses the second rigid substrate comprises a non-glass layer, wherein the non-glass layer comprises a polycarbonate (PC) material (para.62 disclose it can be made of a polycarbonate material). Regarding claim 12, Ishii discloses the multi-layer structure is configured for installation in a vehicle (para.81), the first rigid substrate is configured to face an exterior environment of the vehicle, and the second rigid substrate is configured to face an interior environment of the vehicle (para.81 and fig.1). Regarding claim 13, Ishii discloses the multi-layer structure is configured as a sunroof, a side window, a rear windshield, or a front windshield of the vehicle (see fig.1 and para.81). 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) 3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ishii US 2022/0105710 as applied to claim 1 above, and further in view of Du CN 107247360A (see document of 18263342_2025-12-02_CN_107247360_A_M.pdf). Regarding claim 3, Ishii discloses the first rigid substrate defines a convex exterior surface of the multi-layer structure (see fig.1), and the second rigid substrate defines a concave interior surface of the multi-layer structure (see fig.1). Ishii does not explicitly disclose a cladding is arranged on a top of the first rigid substrate at the perimeter region of the multi-layer structure to serve as an optical shield. Du discloses an apparatus, in at least figs.2, 3 and 6, a cladding (41 and 42, fig.6) is arranged on a top of the first rigid substrate (20 or 20 with 30) at the perimeter region (non-display region) of the multi-layer structure (see fig.6) to serve as an optical shield for the purpose of shielding light and completely covering the non-display region (page 5, the bottom 2nd paragraph). 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 cladding is arranged on a top of the first rigid substrate at the perimeter region of the multi-layer structure to serve as an optical shield as taught by Du in the apparatus of Ishii for the purpose of shielding light and completely covering the non-display region. Claim(s) 3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ishii US 2022/0105710 as applied to claim 1 above, and further in view of Li US 2023/0294605. Regarding claim 3, Ishii discloses the first rigid substrate defines a convex exterior surface of the multi-layer structure (see fig.1), and the second rigid substrate defines a concave interior surface of the multi-layer structure (see fig.1). Ishii does not explicitly disclose a cladding is arranged on a top of the first rigid substrate at the perimeter region of the multi-layer structure to serve as an optical shield. Li discloses an apparatus, in at least fig.1, a cladding (15) is arranged on a top of the first rigid substrate (121 or 121 with 11) at the perimeter region (non-display region) of the multi-layer structure (see fig.1) to serve as an optical shield (para.37) for the purpose of shielding light and hiding the frame glue area (para.37). 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 cladding is arranged on a top of the first rigid substrate at the perimeter region of the multi-layer structure to serve as an optical shield as taught by Li in the apparatus of Ishii for the purpose of shielding light and hiding the frame glue area. Claim(s) 8 and 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ishii US 2022/0105710 as applied to claim 7 above, and further in view of Kusudou US 2017/0361575. Regarding claim 8, Ishii discloses the first rigid substrate (50) comprises a first glass layer (11), a second layer (33), and a laminate layer (13) between the first glass layer and the second layer. Ishii does not explicitly disclose the second layer is a glass layer. Kusudou discloses an analogous art, a rigid substrate (see fig.1) can be a laminate layer (1) between the first glass layer (2a) and the second layer (2b)(para.227) for the purpose of forming a laminated glass with capable of maintaining the sound insulating properties, weather resistance, and heat creep resistance at a high level (see abstract and para.227). 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 rigid substrate can be a laminate layer between the first glass layer and the second layer as taught by Kusudou in the apparatus of Ishii in order to have the second layer is a glass layer for the purpose of forming a laminated glass with capable of maintaining the sound insulating properties, weather resistance, and heat creep resistance at a high level. Regarding claim 9, Ishii discloses the laminate layer (13) comprises a polyvinyl butyral (PVB) material (para.63).
