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 1-21 are 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.
Claim 1 recites the limitation "directly adjacent to the surroundings". There is insufficient antecedent basis for “the surroundings” in the claim. For examination purposes, “the surroundings” will be read as “surroundings”.
Claim 16 recites the limitation “a light source”, while there is already an instance of “a light source” in claim 1, from which it depends. For examination purposes, “a light source” will be read as “the light source”.
Claim 16 recites the limitation “a laminated pane”, while there is already an instance of “a laminated pane” in claim 1, from which it depends. For examination purposes, “a laminated pane” will be read as “the laminated pane”.
Claims 2-21 depend from claim 1, and therefore inherit at least the same deficiencies.
Claims 14, 15, and 17 depend from claim 16, and therefore inherit at least the same deficiencies.
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:

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.
Claims 10 and 11 are rejected under 35 U.S.C. 103 as being unpatentable over Sadakane et al. (2022/0334300) in view of Bellman et al. (2016/0324016).
Regarding claim 10, Sadakane discloses the laminated pane according to claim 1, but fails to teach wherein the optically low refractive index layer is a sol-gel coating in which closed and/or open nanopores are formed. Sadakane and Bellman are related because both teach a laminated pane.
Bellman teaches a laminated pane wherein the optically low refractive index layer is a sol-gel coating in which closed and/or open nanopores are formed (at least Figure 1, 130, crack mitigating layer; [0138]; at least [0009] teaches the refractive index is lower than the refractive index of the film, thus considered a low refractive index layer).
It would have been obvious to one having ordinary skill in the art at the time the invention was filed to have modified Sadakane to incorporate the teachings of Bellman and provide wherein the optically low refractive index layer is a sol-gel coating in which closed and/or open nanopores are formed. Doing so would allow for improved durability to the film without sacrificing the optical characteristics desired.
Regarding claim 11, the modified Sadakane discloses the laminated pane according to claim 10, wherein the low refractive index layer has pores with a size of 1 nm to 500 nm (Bellman: at least [0137]).
Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over Sadakane et al. (2022/0334300) in view of Wu et al. (2024/0184106).
Regarding claim 13, Sadakane discloses the laminated pane according to claim 1, but fails to teach wherein an HUD reflective layer is arranged between the interior-side surface of the outer pane and the interior-side surface of the inner pane. Sadakane and Wu are related because both teach a laminated pane.
Wu teaches a laminated pane wherein an HUD reflective layer is arranged between the interior-side surface of the outer pane and the interior-side surface of the inner pane (at least Figures 1 and 3; 52, first reflective polarizer).
It would have been obvious to one having ordinary skill in the art at the time the invention was filed to have modified Sadakane to incorporate the teachings of Wu and provide wherein an HUD reflective layer is arranged between the interior-side surface of the outer pane and the interior-side surface of the inner pane. Doing so would allow for improved display light with increased brightness to be projected to the human eye.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Anzai (2022/0221718), Morozov (2021/0364792), Nam (2021/0157136), Larson (9,606,355), Shimatani (2017/0052369), Knoll (5,552,935), and Larson (10,509,224) disclose relevant laminated panes.
