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 § 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(s) 1-6 and 10-11 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ngo et al. [WO 2011/103259 A2]. Regarding Claim 1, Ngo et al. shows an electronic package (Figs. 5A-5D with teachings from Figs. 1A-4D), comprising: a package substrate (510, Paragraphs [0016], [0058]); a first region (first region R1, see Drawing A below) in the package substrate (see Figs. 5A-5D), wherein the first region comprises first conductive routing (first region R1 having element 516a); and a second region (second region R2, see Drawing A below) in the package substrate (see Figs. 5A-5D) and laterally spaced apart from the first region (second region R2 laterally spaced apart from first region R1, see Drawing A below), the second region separate and distinct from the first region (second region R2 separate and distinct from first region R1, see Drawing A below), wherein the second region comprises second conductive routing (second region R2 having element 503), and wherein the second conductive routing is embedded in a magnetic material (509, see Figs. 5A-5B, second region R2 having element 503 is at least partially embedded in element 509, see also Fig. 4A, element 403 is embedded in element 403), and a die (529) coupled to the first conductive routing (see Fig. 5B, element 529 coupled to element 516a in first region R1, see Drawing A below), the die entirely outside of a footprint of the magnetic material of the second region in a plan view perspective (see Figs. 5A-5D and Drawing A below, element 529 is entirely outside of a footprint of element 509 of the second region R2 in a plan view perspective). Regarding Claim 2, Ngo et al. shows the package substrate comprises a plurality of layers (see Fig. 4A, element 409 have a plurality of layers), and wherein the magnetic material (409) is disposed through more than one of the plurality of layers (see Fig. 4A). Regarding Claim 3, Ngo et al. shows the magnetic material (409) is disposed through all of the plurality of layers (see Fig. 4A, element 409 is disposed through all of the plurality of layers). Regarding Claim 4, Ngo et al. shows the second conductive routing comprises a conductive loop (see Figs. 5A-5B, Paragraph [0026]). Regarding Claim 5, Ngo et al. shows the conductive loop directly contacts the magnetic material (see Figs. 5A-5B, element 503 directly contacts element 509).

Regarding Claim 10, Ngo et al. shows the second conductive routing is proximate to an edge of the package substrate (see Figs. 5A-5D, second region R2 having element 503 is proximate to an edge of element 510). Regarding Claim 11, Ngo et al. shows the package substrate (510) is a molded substrate (506), an organic substrate, a ceramic substrate, or a glass substrate. In accordance to MPEP 2113, the method of forming the device is not germane to the issue of patentability of the device itself. Therefore, this limitation has not been given patentable weight. Please note that even though product-by-process claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product, i.e. substrate, does not depend on its method of production, i.e. molded. In re Thorpe, 227 USPQ 964, 966 (Federal Circuit 1985). 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. Claim(s) 2-3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ngo et al. in view of We et al. [U.S. Pub. No. 2018/0286562]. Regarding Claim 2, Ngo et al. shows the claimed invention as applied above.

Yosui et al. shows a coil component (Figs. 1-2) teaching and suggesting a surface roughness of the second conductive routing (34A or 35A) is greater than a surface roughness of the first conductive routing (33A, see English translation, Abstract, element 33A have a surface roughness less than the average surface roughness of all interfaces of elements 33A, 34A, 35A so that element 34A or 35A will have a surface roughness greater than element 33A; in addition, element 34A or 35A have a rough surface which will have a surface roughness greater than a surface roughness of a smooth surface of element 33A). Before the effective filing date of the claimed invention, it would have been obvious to a person of ordinary skill in the art to have a surface roughness of the second conductive routing is greater than a surface roughness of the first conductive routing as taught by Yosui et al. for the device as disclosed by Ngo et al. to achieve high bonding strength, small conductor loss and realize excellent high-frequency characteristics (see English translation). Claim(s) 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ngo et al. in view of Yosui et al. [CN 204464431 U] (hereinafter as “Yosui ‘431”).

In addition, it would have been obvious to one having ordinary skill in the art at the time the invention was made to have the first end and the second end are coupled together, since it has been held that forming in one piece an article which has formerly been formed in two pieces and put together involves only routine skill in the art to simplify design and reduce manufacture time and cost. Howard v. Detroit Stove Works, 150 U.S. 164 (1993). Claim(s) 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ngo et al. in view of Nishiwaki et al. [U.S. Pub. No. 2019/0364662].

In addition, in accordance to MPEP 2113, the method of forming the device is not germane to the issue of patentability of the device itself. Therefore, this limitation has not been given patentable weight. Please note that even though product-by-process claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product, i.e. substrate, does not depend on its method of production, i.e. molded. In re Thorpe, 227 USPQ 964, 966 (Federal Circuit 1985). Before the effective filing date of the claimed invention, it would have been obvious to a person of ordinary skill in the art to have the package substrate is a molded substrate, an organic substrate, a ceramic substrate, or a glass substrate as taught by Nishiwaki et al. for the device as disclosed by Ngo et al. to facilitate mechanical stability and reliability to achieve desirable operating characteristics.

In addition, in accordance to MPEP 2113, the method of forming the device is not germane to the issue of patentability of the device itself. Therefore, this limitation has not been given patentable weight. Please note that even though product-by-process claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product, i.e. substrate, does not depend on its method of production, i.e. molded. In re Thorpe, 227 USPQ 964, 966 (Federal Circuit 1985).

Ahrens et al. shows an integrated inductor (Figs. 3c, 3e, 3g) teaching and suggesting the second conductive routing (300 or 360) comprises a first end (304 or 116) embedded in the magnetic material (108) and a second end (306 or 114) embedded in the package substrate (102), and wherein the first end and the second end are coupled together (see Figs. 3c, 3e, 3g, element 304 or 116 and element 306 or 114 are coupled together by being integrated together, Paragraph [0027], see also Figs. 1, 4e, 11c). Before the effective filing date of the claimed invention, it would have been obvious to a person of ordinary skill in the art to have the second conductive routing comprises a first end embedded in the magnetic material and a second end embedded in the package substrate, and wherein the first end and the second end are coupled together as taught by Ahrens et al. for the device as disclosed by We et al. in view of Ngo et al. to achieve a resulting structure that is more stable while obtaining desirable inductance values as required by design requirements (Paragraphs [0041], [0043]). In addition, it would have been obvious to one having ordinary skill in the art at the time the invention was made to have the first end and the second end are coupled together, since it has been held that forming in one piece an article which has formerly been formed in two pieces and put together involves only routine skill in the art to simplify design and reduce manufacture time and cost. Howard v. Detroit Stove Works, 150 U.S. 164 (1993). Claim(s) 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over We et al. in view of Ngo et al. OR Crawford et al. as applied to claim 1 above, and further in view of Nishiwaki et al. [U.S. Pub. No. 2019/0364662]. Regarding Claim 11, We et al. in view of Ngo et al. OR Crawford et al. shows the claimed invention as applied above. In addition, Nishiwaki et al. shows the package substrate is a molded substrate (Paragraph [0031]), an organic substrate (resin, Paragraph [0031]), a ceramic substrate, or a glass substrate. In addition, in accordance to MPEP 2113, the method of forming the device is not germane to the issue of patentability of the device itself. Therefore, this limitation has not been given patentable weight. Please note that even though product-by-process claims are limited by and defined by the process, determination of patentability is based on the product itself. The patentability of a product, i.e. substrate, does not depend on its method of production, i.e. molded. In re Thorpe, 227 USPQ 964, 966 (Federal Circuit 1985). Before the effective filing date of the claimed invention, it would have been obvious to a person of ordinary skill in the art to have the package substrate is a molded substrate, an organic substrate, a ceramic substrate, or a glass substrate as taught by Nishiwaki et al. for the device as disclosed by We et al. in view of Ngo et al. OR Crawford et al. to facilitate mechanical stability and reliability to achieve desirable operating characteristics.

Applicant's arguments filed 10/24/2025 have been fully considered but they are not persuasive. In response to applicant’s arguments that Ngo et al. does not show “the die entirely outside of a footprint of the magnetic material of the second region in a plan view perspective” is found not persuasive because Ngo et al. shows the die entirely outside of a footprint of the magnetic material of the second region in a plan view perspective (see Figs. 5A-5D and Drawing A below, element 529 is entirely outside of a footprint of element 509 of the second region R2 in a plan view perspective). The term “second region” is broad. Based on the broad interpretation of the term “second region”, Drawing A clearly shows an interpretation of second region R2. In response to applicant’s arguments that We et al. does not show “the die entirely outside of a footprint of the magnetic material of the second region in a plan view perspective” is found not persuasive because We et al. shows the die entirely outside of a footprint of the second region (see Fig. 1 and Drawing 1 below, element 123 is entirely outside of a footprint of element 140 of second region R2 in a plan view perspective). In response to applicant’s arguments that Crawford et al. does not show “the die entirely outside of a footprint of the magnetic material of the second region in a plan view perspective” is found not persuasive because Crawford et al. shows the die entirely outside of a footprint of the second region (see Fig. 4 and Drawing 5 below, element 410 is entirely outside of a footprint of element 110 or 530 of second region R2 in a plan view perspective). Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
