With respect to claim 27, Tajima teaches the coil component of claim 23, wherein a magnetic material and a resin of the body provide the outer surface of the coil component (col. 3, lines 6-10).
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.
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.
Claims 4, 5, 8-10, 25 and 26 are rejected under 35 U.S.C. 103 as being unpatentable over Tajima, as applied to claims 3 and 23 above, in view of Lim et al. (U.S. PG. Pub. No. 2020/0035404 A1).
With respect to claims 4 and 25, Tajima teaches the coil component of claims 3 and 23, respectively. Tajima does not expressly teach a surface roughness of a surface of the lead-out portion in contact with the first metal layer is different from a surface roughness of the outermost surface of the external electrode.
Lim et al., hereinafter referred to as “Lim,” teaches a coil component 1000 (FIGs. 1-10), wherein a surface roughness of a surface (surface in contact with metal layer 410) of the lead-out portion 232 in contact with the first metal layer 410 is different from a surface roughness of the outermost surface (outer surface of electrode 400) of the external electrode (col. 15, lines 36-41). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to have the surface roughness as taught by Lim to the coil component of Tajima to improve cohesion force between the lead-out portion and the metal layer (col. 15, lines 36-41).
With respect to claims 5 and 26, Tajima in view of Lim teaches the coil component of claims 4 and 25, respectively, wherein the surface roughness of the surface of the lead-out portion in contact with the first metal layer is greater than the surface roughness of the outermost surface of the external electrode (Lim, col. 15, lines 36-41).
With respect to claim 8, Tajima teaches the coil component of claim 1. Tajima does not expressly teach
a substrate disposed in the body to support the coil portion,
wherein the coil portion further includes:
first and second coil patterns respectively disposed on one surface and the other surface of the substrate; and
a via passing through the substrate to connect inner ends of the first and second coil patterns to each other.
Lim teaches a coil component 1000 (FIGs. 1-10) comprising:
a substrate IL disposed in the body 100 to support the coil portion 200,
wherein the coil portion further includes:
first and second coil patterns 212 and 211 respectively disposed on one surface and the other surface of the substrate; and
a via 221 passing through the substrate to connect inner ends of the first and second coil patterns to each other (col. 4, lines 10-26, col. 6, lines 47-49 and 59-64).
It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to have the substrate and via connection as taught by Lim to the coil component of Tajima to improve mechanical stability of the coil portion and to increase inductance.
With respect to claim 9, best understood in view of 35 USC 112(b) rejection, Tajima in view of Lim teaches the coil component of claim 8, wherein the lead-out portion 242 and 232 includes:
a lead-out pattern 242 disposed on the one surface of the substrate to be connected to the coil pattern; and
a sub-lead-out pattern disposed on the other surface of the substrate to be spaced apart from the coil pattern (Lim, col. 6, lines 64 to col. 7, line 2).
With respect to claim 10, Tajima in view of Lim teaches the coil component of claim 9, further comprising:
a sub-via 223 passing through the substrate to connect the lead-out pattern and the sub-lead-out pattern to each other (Lim, col. 7, lines 5-13).
Claim 24 is rejected under 35 U.S.C. 103 as being unpatentable over Tajima, as applied to claim 23 above, in view of Suzuki (U.S. PG. Pub. No. 2018/0286568 A1).
With respect to claim 24, Tajima teaches the coil component of claim 23, wherein
the body has a plurality of surfaces 13-18 (annotated FIG. 1 above) (col. 3, lines 14-21). Tajima does not expressly teach the external electrode is disposed on or in only one of the plurality of surfaces.
Suzuki teaches a coil component 10 (Fig. 3), wherein the external electrode 20A or 20B is disposed on or in only one of the plurality of surfaces (surface 7a) (para. [0028]). It would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to have the electrode in only one surface as taught by Suzuki to the coil component of Tajima to facilitate manufacturing.
