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.
Rejection Note: Italicized claim limitations indicate limitations that are not explicitly disclosed in the primary reference (or combination of references), but are disclosed or rendered obvious by secondary references or remarks.
Claims 1, 3-4, 6-7, 14, 16, 18-19, 22-25, 27-29, and 32 are rejected under 35 U.S.C. 103 as being unpatentable over Lee (US 20160302308 A1) in view of Pietambaram (US 20230080454 A1).
Regarding claim 1, Lee discloses a package (Fig. 3, an intermediate assembly), comprising:
an inorganic carrier body (See annotated figure; [0049]: “a general core board”) having a cavity (101);
an organic integrated circuit substrate (10; [0066]: “insulating resin”; [0143]: “insulating resin”) embedded in the cavity of the inorganic carrier body; and
a redistribution structure (43/113/139 with 240/130/240) formed partially on (at least indirectly “on”) and/or above (See annotated figure for direction designation) the inorganic carrier body and partially on (at least indirectly “on”) and/or in the organic integrated circuit substrate (the redistribution structure includes 43/240 which are components of substrate 10);
wherein part of the redistribution structure (43 and 240) extends into the cavity (43 and 240 are within cavity 101);
wherein at least one layer structure (139) of the redistribution structure is formed on (at least indirectly “on”) and/or above (See annotated figure for direction designation) the inorganic carrier body and on (at least indirectly “on”) and/or above (See annotated figure for direction designation) the organic integrated circuit substrate.
Illustrated below is a marked and annotated figure of Fig. 3 of Lee.

Lee fails to teach material composition of the carrier body. Thus, Lee fails to teach “an inorganic carrier body”.
Pietambaram discloses a carrier body (Fig. 1A: 104) may be formed from a finite selection of known suitable materials, and these materials include an inorganic carrier body ([0072]: “glass”). Modifying the carrier body of Lee by incorporating the material composition of Pietambaram would arrive at the claimed inorganic carrier body configuration. A person of ordinary skill in the art before the effective filing date would have had a reasonable expectation of success doing so because in each situation the carrier body is performing the same function as a core (Lee: [0049]: “a general core board”; Pietambaram: [0072]: “core”). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to have the claimed inorganic carrier body configuration because it is incorporating a material composition known useful in the same situation. MPEP 2143 (I)(E).

Regarding claim 4, Lee in view of Pietambaram discloses the package according to claim 1 (Lee: Fig. 3), wherein at least one layer structure (43) of the redistribution structure is formed only on and/or in the organic integrated circuit substrate without extending to the inorganic carrier body (layer 43 is exclusive to substrate 10).
Regarding claim 6, Lee in view of Pietambaram discloses the package according to claim 1 (Lee: Fig. 3), wherein at least one layer structure (43) of the redistribution structure is formed as an integral part of the organic integrated circuit substrate (layer 43 is integral to substrate 10).
Regarding claim 7, Lee in view of Pietambaram discloses the package according to claim 1 (Lee: Fig. 3), wherein the package has at least one of the following features (Note: one feature is cited below, thus meeting the claim):
wherein an exterior surface of the redistribution structure is substantially planar (See dashed reference line for “substantially planar shape”);
wherein an interior surface of the redistribution structure is profiled;
wherein the inorganic carrier body comprises at least one of glass, ceramic, metal, highly rigid functional materials, and optionally further comprises an organic carrier, including carbon composite and/or aramid composite;
wherein the inorganic carrier body consists only of glass;
wherein at least one main surface of the organic integrated circuit substrate comprises electrically conductive connection bumps but no wiring lines;
wherein the inorganic carrier body is free of interior electrically conductive connection structures or comprises at least one electrically conductive connection structure in an interior of the inorganic carrier body;
wherein a surface roughness Ra of the inorganic carrier body is not more than 100 nm;
wherein the organic-integrated circuit substrate comprises a laminated layer stack comprising at least one electrically conductive layer structure and at least one electrically insulating layer structure;
wherein an electronic component is mounted on the redistribution structure;
wherein the organic integrated circuit substrate is configured for providing a voltage regulation function, a heat management function, a power supply function, a high-frequency application function, a signal processing function and/or an amplifier function;
wherein the organic integrated circuit substrate is embedded in the cavity of the inorganic carrier body so as to suppress warpage and/or enhance mechanical stability of the organic integrated circuit substrate;
wherein at least one capacitor formed on the inorganic carrier body and/or embedded in the organic integrated circuit substrate.
Regarding claim 14, Lee in view of Pietambaram discloses the package according to claim 1 (Lee: Fig. 3), further comprising: a layer build-up (125) on (at least indirectly “on”) a side (under side, See annotated figure for direction designation) of the inorganic carrier body and the organic integrated circuit substrate opposite the redistribution structure (vertically “opposite”, See annotated figure for direction designation), wherein the layer build-up and the redistribution structure are asymmetric (there are different numbers of layers for these structures, thus vertically asymmetric).
Regarding claim 16, Lee in view of Pietambaram discloses the package according to claim 14 (Lee: Fig. 3), wherein the redistribution structure has a higher integration density than the layer build-up (there are different numbers of layers for these structures, thus “the redistribution structure has a higher integration density” because of these additional layers).
Regarding claim 18, Lee in view of Pietambaram discloses the package according to claim 1 (Lee: Fig. 3), further comprising: a dielectric filling medium (160; [0067]: “interlayer insulating material”) covering (directly “covering”) at least part of at least one vertical sidewall (See annotated figure for sidewall designations) and/or at least part of at least one horizontal wall of the inorganic carrier body and/or of the organic integrated circuit substrate.
Regarding claim 19, Lee in view of Pietambaram discloses the package according to claim 18 (Lee: Fig. 3), wherein the dielectric filling medium spatially separates the inorganic carrier body with respect to the redistribution structure (160 separates the carrier body from at least 43/240).
Regarding claim 22, Lee in view of Pietambaram discloses the package according to claim 1 (Lee: Fig. 3), but the combination as applied only cites a single cavity and circuit substrate, and thus fails to teach
“wherein the inorganic carrier body has a further cavity;
Wherein the package comprises a further organic integrated circuit substrate embedded in the further cavity of the inorganic carrier body; and
wherein the redistribution structure is formed partially on and/or in the further organic integrated circuit substrate.”
Pietambaram discloses a package (Fig. 1A) with an inorganic carrier body (104, as cited above for claim 1) and a cavity (112(1)) with a circuit substrate (114(1)),
wherein the inorganic carrier body has a further cavity (112(2));
wherein the package comprises a further organic integrated circuit substrate (114(2)) embedded in the further cavity of the inorganic carrier body
Modifying the package of Lee in view of Pietambaram by incorporating a duplicated cavity and organic integrated circuit substrate in the same way disclosed by Pietambaram would arrive at the claimed package configuration
wherein the inorganic carrier body has a further cavity (duplicated Lee: Fig. 3: 101);
wherein the package comprises a further organic integrated circuit substrate (duplicated Lee: Fig. 3: 10) embedded in the further cavity of the inorganic carrier body; and
wherein the redistribution structure (Lee: Fig. 3: the same redistribution structure as in claim 1, applied in the same way to these duplicated structures) is formed partially on and/or in the further organic integrated circuit substrate.
A person of ordinary skill in the art before the effective filing date would have had a reasonable expectation of success doing so because in each situation the circuit substrate is performing at least the same function to interconnect electronic components (Lee: [0109]: “connecting…electronic components…to each other”; Pietambaram: [0077]: “a bridge die”). Pietambaram teaches a design incentive to motivate one of ordinary skill in the art before the effective filing date to incorporate the duplication of parts in that the circuit substrates are designed and chosen according to required interconnection and function of the package ([0077]: “different types of IC die…depending on desired functionalities, performance, cost and manufacturing considerations”). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to have the claimed duplication of parts because it is a duplication encompassed within the prior art according to design requirement. MPEP 2143 (I)(F); MPEP 2144.04 (VI)(B).
Regarding claim 23, Lee in view of Pietambaram discloses the package according to claim 22 (Lee: Fig. 6), further comprising:
an electronic component (Fig. 6: 501; [0101]: “electronic components”) mounted on the redistribution structure (mounted on the Fig. 3 embodiment in the same way as with the Fig. 6/Fig. 1 embodiment) above the organic integrated circuit substrate (above, without requiring any specific overlap in any particular direction); and
a further electronic component (502; [0101]: “electronic components”) mounted on the redistribution structure (mounted on the Fig. 3 embodiment in the same way as with the Fig. 6/Fig. 1 embodiment) above the further organic integrated circuit substrate (above, without requiring any specific overlap in any particular direction).

Regarding claim 24, Lee in view of Pietambaram discloses the package according to claim 22 (Pietambaram: Fig. 1A), wherein the organic integrated circuit substrate and the further organic integrated circuit substrate are configured for providing different functions ([0077]: “different types of IC die 114”).
Regarding claim 25, Lee in view of Pietambaram discloses the package according to claim 1 (Lee: Fig. 3, an intermediate assembly), further comprising:
an electronic component (Fig. 6: 501; [0101]: “electronic components”) and a further electronic component (502; [0101]: “electronic components”) mounted on the redistribution structure (mounted on the Fig. 3 embodiment in the same way as with the Fig. 6/Fig. 1 embodiment), the redistribution structure being configured as a bridge ([0109]: “connecting…electronic components…to each other”) between the electronic component and the further electronic component.
Regarding claim 27, Lee in view of Pietambaram discloses the package according to claim 1 (Lee: Fig. 3), but the combination as applied fails to teach “further comprising: an optical communication path extending through the inorganic carrier body”.
Pietambaram discloses a package further comprising: an optical communication path (Fig. 1A: path 106) extending through the inorganic carrier body (body 104). Modifying the inorganic carrier body of Lee in view of Pietambaram by including the optical communication path of Pietambaram would arrive at the claimed carrier body configuration. A person of ordinary skill in the art before the effective filing date would have had a reasonable expectation of success doing so because in each situation the carrier body is performing the same function as a core (Lee: [0049]: “a general core board”; Pietambaram: [0072]: “core”). Pietambaram provides a teaching to motivate one of ordinary skill before the effective filing date to include the optical communication path in that it would enable improved cost, size, and performance when connecting with external systems ([0076]: “can enable simpler, faster, more compact, low-cost, compatible assembly, and in some cases, more reliable connections with optoelectronic systems”). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to have the claimed optical communication path because it would enable improved connections with external systems. MPEP 2143 (I)(G).
Regarding claim 28, Lee in view of Pietambaram discloses the package according to claim 1 (Lee: Fig. 3), comprising at least one of the following features:
wherein the redistribution structure has a first region with a first pitch and a second region with a second pitch, the second pitch being different from the first pitch;
wherein the redistribution structure has a first pitch on and/or above (choosing “above” for the reference interpretation, without requiring any specific overlap in any specific direction) the inorganic carrier body differing from a second pitch having a larger pitch than the first pitch, on and/or in the organic integrated circuit substrate ([0054]: “a pitch smaller than that of the circuit layers of the circuit board”. Note: the cited portion of the reference is relied upon to teach a “larger”/smaller relation among these pitches).
Regarding claim 29, Lee in view of Pietambaram discloses the package according to claim 1 (Lee: Fig. 3), wherein at least part of the inorganic carrier body is coated (indirectly “coated”) with a functional coating (150, performing the function of a solder mask; [0068]: “solder resist layers”).
Note that claim 1 was previously addressed above, however, it’s being addressed differently here based on the reading of the reference, particularly to the cited embodiment in order to address the dependent claim 3.
Regarding claim 1, Lee discloses a package (Fig. 2, an intermediate assembly), comprising:
an inorganic carrier body (See annotated figure; [0049]: “a general core board”) having a cavity (101);
an organic integrated circuit substrate (10; [0066]: “insulating resin”; [0143]: “insulating resin”) embedded in the cavity of the inorganic carrier body; and
a redistribution structure (115 with 10A; combined with Fig. 3: extra redistribution parts 139. Note: [0092]: “may be simultaneously formed…design freedom…may be improved” teaches these features of the separate embodiments are combinable based on design requirement) formed partially on (at least indirectly “on”) and/or above the inorganic carrier body and partially on and/or in the organic integrated circuit substrate;
wherein part of the redistribution structure (Fig. 2: 52 and Fig. 2: 140) extends into the cavity (52/analogous Fig. 3: 43 and 140/analogous Fig. 3: 240 are within cavity 101);
wherein at least one layer structure (139) of the redistribution structure is formed on (at least indirectly “on”) and/or above (See annotated figure for direction designation) the inorganic carrier body and on (at least indirectly “on”) and/or above (See annotated figure for direction designation) the organic integrated circuit substrate.

Lee fails to teach material composition of the carrier body. Thus, Lee fails to teach “an inorganic carrier body”.
Pietambaram discloses a carrier body (Fig. 1A: 104) may be formed from a finite selection of known suitable materials, and these materials include an inorganic carrier body ([0072]: “glass”). Modifying the carrier body of Lee by incorporating the material composition of Pietambaram would arrive at the claimed inorganic carrier body configuration. A person of ordinary skill in the art before the effective filing date would have had a reasonable expectation of success doing so because in each situation the carrier body is performing the same function as a core (Lee: [0049]: “a general core board”; Pietambaram: [0072]: “core”). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to have the claimed inorganic carrier body configuration because it is incorporating a material composition known useful in the same situation. MPEP 2143 (I)(E).
Regarding claim 3, Lee in view of Pietambaram discloses the package according to claim 1 (Lee: Fig. 2), wherein the redistribution structure has a larger (“larger” because it extends outside of the dashed reference lines) vertical extension on and/or in the organic integrated circuit substrate (See annotated figure for vertical extension designation) than on and/or above the inorganic carrier body (See annotated figure for vertical extension designation).
Regarding independent claim 32, Lee discloses a method of manufacturing a package (Fig. 3), the method comprising:
providing an inorganic carrier body (See annotated figure; [0049]: “a general core board”) having a cavity (101);
embedding an organic integrated circuit substrate (10; [0066]: “insulating resin”; [0143]: “insulating resin”) in the cavity of the inorganic carrier body; and
forming a redistribution structure (43/113/139 with 240/130/240) partially on (at least indirectly “on”) and/or above (See annotated figure for direction designation) the inorganic carrier body and partially on (at least indirectly “on”) and/or in the organic integrated circuit substrate (the redistribution structure includes 43/240 which are components of substrate 10);
wherein part of the redistribution structure (43 and 240) extends into the cavity (43 and 240 are within cavity 101);
wherein at least one layer structure (139) of the redistribution structure is formed on (at least indirectly “on”) and/or above (See annotated figure for direction designation) the inorganic carrier body and on (at least indirectly “on”) and/or above (See annotated figure for direction designation) the organic integrated circuit substrate.
Lee fails to teach material composition of the carrier body. Thus, Lee fails to teach the method having “an inorganic carrier body”.
Pietambaram discloses a method with a carrier body (Fig. 1A: 104) may be formed from a finite selection of known suitable materials, and these materials include an inorganic carrier body ([0072]: “glass”). Modifying the carrier body in the method of Lee by incorporating the material composition of Pietambaram would arrive at the claimed method and inorganic carrier body configuration. A person of ordinary skill in the art before the effective filing date would have had a reasonable expectation of success doing so because in each situation the carrier body is performing the same function as a core (Lee: [0049]: “a general core board”; Pietambaram: [0072]: “core”). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to have the claimed method and inorganic carrier body configuration because it is incorporating a material composition known useful in the same situation. MPEP 2143 (I)(E).
Claim 20 is rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Pietambaram as applied to claim 18 above, and further in view of Wang (US 20230061932 A1).
Regarding claim 20, Lee in view of Pietambaram discloses the package according to claim 18, but fails to teach specific characteristics of the dielectric filling medium. Thus, Lee in view of Pietambaram fails to teach “wherein the dielectric filling medium comprises a dielectric having a Young’s modulus of not more than 5 GPa”.
Wang discloses wherein the dielectric filling medium (Fig. 1D: 162) comprises a dielectric ([0058]: “epoxy glue, silicon glue, resin, rubber, poly ethylene (PE), polyimide” includes a plurality of known dielectrics) having a Young’s modulus of not more than 5 GPa ([0056]: “about 0.2 GPa to about 6 GPa” substantially overlaps the claimed range). Modifying the dielectric filling medium of Lee in view of Pietambaram by including a medium disclosed by Wang would arrive at the claimed Young’s modulus configuration. A person of ordinary skill in the art before the effective filing date would have had a reasonable expectation of success doing so because in each situation a resinous medium (Lee: medium 160, [0067]: “resin”; Wang: medium 162, [0058]: “resin”) is filling a cavity (Lee: Fig. 3: cavity 101; Wang: Fig. 1D: cavity 161a). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to have the claimed Young’s modulus configuration because it is a characteristic of an otherwise known dielectric filling medium. MPEP 2112.01.

Response to Arguments
Applicant's arguments filed 9/3/2026 have been fully considered but they are not persuasive.
Applicant argues:
Applicant argues with respect to amended claims 1 and 32 that “These limitations do not merely require separate conductive structures associated with two adjacent bodies. Rather, amended claim 1 requires a particular hybrid redistribution architecture in which the redistribution structure both extends into the cavity and includes at least one layer structure formed on and/or above both the inorganic carrier body and the organic integrated circuit substrate embedded in the cavity of that inorganic carrier body”. Remarks at pg. 13.
Examiner’s reply:
The examiner disagrees and points to MPEP 2111: Broadest Reasonable Interpretation. The examiner finds “the redistribution structure…at least one layer structure of the redistribution structure” reasonably encompassing structural configurations of redistribution structures beyond the specifically contended configuration of Applicant’s disclosure. More specifically, the claim as written still reasonably includes a plurality of configurations with two separate and distinct pieces. Accordingly, the rejection is maintained in substantially the same way as before, with adjustments to the citations and remarks as necessitated by claim amendment and to promote clarity of the record.
Conclusion
THIS ACTION IS MADE FINAL. 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.
