Office Action

§102 §103 §112
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: 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(s) 1-2, 4, 6, & 14 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Yosui et al. (US PGPub 20170149111) As per claim 1: Yosui et al. discloses in Fig. 1 & 13B: A transmission line comprising: a substrate (insulator layers 11-14) that is insulating and extends in a predetermined direction (as seen in Fig. 1); a high-frequency signal transmission line (first signal conductor pattern 31) included in the substrate; a differential signal transmission line (32A/B, [0066]) included in the substrate; and a power supply line (40 with connected plane 23, [0106]) included in the substrate; wherein: the power supply line and the high-frequency signal transmission line are in parallel or substantially in parallel to each other (abstract); the differential signal transmission line is between the power supply line and the high-frequency signal transmission line (32 is between 23 and 31); and in the substrate where the high-frequency signal transmission line and the differential signal transmission line are closest and parallel or substantially parallel to each other, the power supply line, the differential signal transmission line, and the high-frequency signal transmission line are aligned with each other in a thickness direction of the substrate (23, 32, and 31 are all stacked and centered over each other in the thickness direction of 13B). As per claim 2: Yosui et al. discloses in Fig. 1 & 13B: a ground conductor (21) between at least one of the power supply line and the differential signal transmission line or the differential signal transmission line and the high-frequency signal transmission line. As per claim 4: Yosui et al. discloses in Fig. 1, 2B, & 13B: the substrate includes a curved section at a middle position of the substrate in the direction in which the substrate extends (as seen in Fig. 2B and described in [0055] and [0028]). As per claim 6: Yosui et al. discloses in Fig. 1 & 13B: the substrate includes a plurality of insulating resin materials (insulating layers 11-15) that separate the high-frequency signal transmission line, the differential signal transmission line included in the substrate, and the power supply line from one another ([0055], as seen in Fig. 13B). As per claim 14: Yosui et al. discloses in Fig. 1 & 13B: the high-frequency signal transmission line and the power supply line are spaced away from each other at a distance equal or substantially equal to a size of the differential signal transmission line (as seen in Fig. 13B, where the high-frequency signal transmission line is considered to include insulative layers 13 & 14, and the differential signal transmission line size includes insulative layers 11 & 12). 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) As per claim 11: Yosui discloses in Fig. 10: the differential signal transmission line includes a first differential signal transmission line (32) and a second differential signal transmission line (33) Yosui does not disclose in Fig. 13B: 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: the substrate includes: a first section where the high-frequency signal transmission line is located (insulative layers 13 & 14); a second section (protective layer 9) where the power supply line is located; and a third section (insulative layers 11 & 12) where the differential signal transmission line is located. 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. The resultant combination discloses the transmission line of claim 5, as rejected above. As per claim 13: The resultant combination discloses in Yosui: the first section includes an insulating resin material ([0055]); The resultant combinaiton does not disclose: 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. Kawaguchi et al. discloses in Fig. 1: A power supply line configured with transmission lines (12), wherein the power supply line includes is formed on a resin material ([0135]) and includes a material (resistive material 14) that is higher in heat resistance and heat dissipation (conductive ceramics, [0124, 0131]) than the insulating resin material. 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. Claim(s) 7-10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yosui et al. (US PGPub 20170149111) in view of Dagostino (US Patent 6867668) As per claim 7: Yosui et al. does not disclose: a first ground conductor on a first main surface of the substrate. Dagostino discloses in Fig. 8A: A flexible transmission line (flexible dielectric layer 152) comprising a plurality of signal conductors (154), wherein the transmission line comprises a first ground conductor (148) on a first main surface of a substrate (152) and a second ground conductor (150) on a second main surface of a substrate. At the time of filing, it would have been obvious to one of ordinary skill in the art to provide the ground conductors of Dagostino to the transmission line of Yosui et al. to provide the benefit of reducing electromagnetic interference emissions, as taught by Dagostino (col. 7 lines 7-29). As per claim 8: Yosui et al. does not disclose: a width of the differential signal transmission line is smaller than a width of the first ground conductor. Dagostino discloses in Fig. 8A: A flexible transmission line (flexible dielectric layer 152) comprising a plurality of signal conductors (154), wherein the transmission line comprises a first ground conductor (148) on a first main surface of a substrate (152) and a second ground conductor (150) on a second main surface of a substrate. Wherein the width of the ground conductors exceeds that of the transmission lines. At the time of filing, it would have been obvious to one of ordinary skill in the art for the ground conductors of the combination of claim 7 to have a larger width an a width of the differential signal transmission line to provide the benefit of effectively reducing electromagnetic interference emissions, as taught by Dagostino (col. 7 lines 7-29), and is well understood in the art. As per claim 9: Yosui et al. does not disclose: a second ground conductor on a second main surface of the substrate that opposes the first main surface of the substrate. Dagostino discloses in Fig. 8A: A flexible transmission line (flexible dielectric layer 152) comprising a plurality of signal conductors (154), wherein the transmission line comprises a first ground conductor (148) on a first main surface of a substrate (152) and a second ground conductor (150) on a second main surface of a substrate. As a consequence of the combination of claim 7, the combination discloses a second ground conductor on a second main surface of the substrate that opposes the first main surface of the substrate. As per claim 10: Yosui et al. does not disclose: the first ground conductor and the second ground conductor are not connected to each other. Dagostino discloses in Fig. 8A: A flexible transmission line (flexible dielectric layer 152) comprising a plurality of signal conductors (154), wherein the transmission line comprises a first ground conductor (148) on a first main surface of a substrate (152) and a second ground conductor (150) on a second main surface of a substrate. Dagostino further discloses: the first ground conductor and the second ground conductor are not connected to each other (no ground vias 138 are shown in Fig. 8A, with Dagostino specifically noting ground vias as optional, description para 14). As a consequence of the combination of claim 7, the first ground conductor and the second ground conductor are not connected to each other.
