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 Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claims 3 & 12 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claims 3 & 12 provide limitations requiring both a data transmission line and a control signal transmission line, described as per the embodiment of Fig. 7, wherein the various lines are aligned along a width direction of the substrate, not a thickness direction. Claim 1 provides a limitation wherein the various lines are aligned along a thickness direction, as seen in the embodiment of Fig. 8. The specification provides no written description to disclose how the combination of the embodiment of Fig. 7 comprising a data transmission line and a control signal transmission line would result in a comparative distance with respect to either the power supply line or the high-frequency signal line of the embodiment of Fig. 8. Fig. 7 discloses the respective data and control signal transmission lines positioned side-by-side and aligned in the width direction, such that the combination with Fig. 8 would not result in either data or control signal transmission lines being closer to the power supply line or the high-frequency signal line in respect to each other. As such, claims 3 & 12 fail to meet the written description requirement.
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
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) 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yosui et al. (US PGPub 20170149111)

the differential signal transmission line includes a first differential signal transmission line and a second differential signal transmission line; and a width of the first differential signal transmission line is equal or substantially equal to a width of the second differential signal transmission line.
At the time of filing, it would have been obvious to one of ordinary skill in the art for the differential signal transmission line to include a first differential signal transmission line and a second differential signal transmission line, to provide the benefit of multiple differential signal transmission lines as is well known in the art and shown in Fig. 10 of Yosui et al.
It would be further obvious for a width of the first differential signal transmission line is equal or substantially equal to a width of the second differential signal transmission line as one of a limited number of options (same or different), wherein the width of the differential signal transmission line is a design parameter for determining the characteristic impedance of the transmission line, as is well understood in the art.
Claim(s) 5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yosui et al. (US PGPub 20170149111) in view of Chen et al. (US PGPub 20160174361)
As per claim 5:
Yosui et al. discloses in Fig. 1 & 13B:

Yosui does not disclose:
the first section, the second section, and the third section are made of different materials from each other.
Chen et al. discloses in Fig. 3:
A multi-layer substrate comprising a plurality of transmission line layers (signal layers 302), and power layers (306) separated by a plurality of dielectric layers 308, wherein the dielectric layer material is a design parameter chosen based on thermal, electrical, and/or mechanical characteristics ([0070]), wherein suitable dielectric materials can include many different options ([0084]).
At the time of filing, it would have been obvious to one of ordinary skill in the art for the respective dielectric material of each section of Yosui to be individually determined as a design parameter based on desired thermal, electrical or mechanical characteristics, as taught by Chen et al. ([0070]) and further as is it is well understood in the art that the dielectric constant of a material affects the impedance of a transmission line.
It would be further obvious for the first section, the second section, and the third section to be made of different materials from each other as one of a limited number of options (different or same) for the design parameter of the dielectric material.
Claim(s) 13 is/are rejected under 35 U.S.C. 103 as being unpatentable over the resultant combination of Yosui et al. (US PGPub 20170149111) in view of Chen et al. (US PGPub 20160174361) as applied to claim 5 above, and further in view of Kawaguchi et al. (US PGPub 20100201459) and Chen et al. (US PGPub 20130271909), hereinafter Chen 2.

Chen 2 discloses:
The use of a filler magnetic substance (common mode filter 308, [0021]) in the insulating material of differential transmission lines.
At the time of filing, it would have been obvious to one of ordinary skill in the art to provide the resistive material of Kawaguchi et al. to the second section of the resultant combination to provide the benefit of suppressing transmission noise through a power supply line, as taught by Kawaguchi et al. (abstract)
It would be further obvious for the insulating resin material of the third section to include the filler magnetic substance of Chen 2 to provide the benefit of filtering a common mode from the differential transmission lines, as per Chen 2 (abstract, and being a common mode filter).
As a consequence of the combination, the combination discloses the second section includes a material that is higher in heat resistance and heat dissipation than the insulating resin material of the first section; and the third section includes an insulating resin material with a filler magnetic substance.
