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 .
Election/Restrictions
Claims 17 – 19 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected Invention II (method claims), there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 05/15/2026.
Allowable Subject Matter
Claims 4, 10, 13 and 14 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Claim Objections
Claim 1 is objected to because of the following informalities: Claim 1 states “located on the negative main surface of the insulator layer located farther in the negative direction”. This would seem to be missing “first” and may be written as “located on the negative main surface of the first insulator layer located farther in the negative direction”. Appropriate correction is required.
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.

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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 3 is rejected under 35 U.S.C. 103 as being unpatentable over Hayashi (US 2013/0153279 A1; herein referenced as “Hayashi’279”) as applied to claim 1 above, and further in view of Stahr (US 10,356,904 B2).
Regarding Claim 3, Hayashi’279 further discloses the circuit board (Fig 1-5) according to claim 1, wherein the plurality of insulator layers include a third insulator layer (lower 14 in Fig 1); the third insulator layer (lower 14) has a Young's modulus ([0031]) at room temperature ([0033]) higher than the Young's modulus at room temperature of the first insulator layer (13), and is located farther in the negative direction of the Z-axis than the first insulator layer (lower 14 is on a lower surface of uppermost 13 in Fig 1), and is in contact with the first insulator layer (13); and the insulator layer located farther in the negative direction of the Z-axis than the second insulator layer (uppermost 14 in Fig 1) is the third insulator layer (lower 14 in Fig 1).
Hayashi’279 does not disclose the through-hole passes through the third insulator layer in the Z-axis direction.
Stahr (US 10,356,904 B2) teaches of a circuit board (Fig 4) wherein a through-hole (Column 4, lines 6-18) passes through a third insulator layer (102) in the Z-axis direction.
It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the board as disclosed by Hayashi’279, wherein the through-hole passes through the third insulator layer in the Z-axis direction as taught by Stahr, in order to transmit electric signals and allow operation of an electronic device with electrical connections through a support structure (Column 3, lines 30-50) and furthermore since it has been held that mere duplication of the essential working parts of a device involves only routine skill in the art in order to transmit electric signals and allow operation of an electronic device with electrical connections through a support structure.

Claim(s) 7 is rejected under 35 U.S.C. 103 as being unpatentable over Hayashi (US 2013/0153279 A1; herein referenced as “Hayashi’279”) as applied to claim 1 above, and further in view of Sakai (US 2014/0209356 A1).
Regarding Claim 7, Hayashi’279 discloses the limitations of the preceding claim.
Hayashi’279 does not disclose the circuit board according to claim 1, wherein when viewed in the Z-axis direction, an area of an end of the interlayer connection conductor in the positive direction of the Z-axis is smaller than an area of an end of the interlayer connection conductor in the negative direction of the Z-axis.
Sakai (US 2014/0209356 A1) teaches of a circuit board (Fig 8) wherein when viewed in the Z-axis direction (though this view is not shown, all views would meet this structural limitation as seen in Fig 8), an area ([0095-0097] vias shown have diameter) of an end of an interlayer connection conductor (15) in a positive direction (upward in Fig 8) of the Z-axis is smaller than an area ([0095-0097] vias shown have diameter) of an end of the interlayer connection conductor (15) in the negative direction of the Z-axis (vias taper such that the diameter is greater towards the lower end of Fig 8).
It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the board as disclosed by Hayashi’279, wherein when viewed in the Z-axis direction, an area of an end of the interlayer connection conductor in the positive direction of the Z-axis is smaller than an area of an end of the interlayer connection conductor in the negative direction of the Z-axis as taught by Sakai, in order to provide high frequency characteristics, to permit distance between lower wirings to be increased and allow distances between upper wirings or at a mounting surface to reduce (Sakai, [0096,0104-0114]).
Claim(s) 12 is rejected under 35 U.S.C. 103 as being unpatentable over Hayashi (US 2013/0153279 A1; herein referenced as “Hayashi’279”) as applied to claim 1 above, and further in view of Nakamura (US 2016/0133555 A1).

It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the board as disclosed by Hayashi’279, wherein a thickness of the second insulator layer in the Z-axis direction is smaller than a thickness of the first insulator layer in the Z-axis direction as taught by Hayashi’067, in order to provide reliability, reduce disconnections, suppress separation, prevent short-circuiting and control rigidity (Hayashi’067, [0005,0026-0037,0049,0059]). The combination would also allow control of the overall thickness of the circuit board which would then provide functionality of the space intended for the circuit board to be placed within.
