Office Action

§103
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 . Information Disclosure Statement The information disclosure statement (IDS) submitted on 6/8/2023 is being considered by the examiner. Status of Claims This office action is in response to "Claims filed on 5/8/2026". Applicant's amendments of claims 1, 9, 21; cancellation of claims 13-20 with the same reply have been entered by the Examiner. Upon entry of the amendments, claims 1-12, 21-28 are pending wherein claims 1, 9 and 21 are independent. 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. Note applicable to all claims being rejected in this Office action: Examiner notes that the limitations "overlap", "layer", "portion" “embed” are being interpreted broadly in accordance with MPEP. Per MPEP 2111 and 2111.01, the claims are given their broadest reasonable interpretation and the words of the claims are given their plain meaning consistent with the specification without importing claim limitations from the specification. The claim presently discloses a structural limitation (i.e. overlap, layer, portion, contact) that is taught by prior art of record, therefore, the limitation is considered met by the prior art of record. Additionally, Merriam Webster dictionary defines the above limitations as “to occupy the same area in part”, “one thickness lying over or under another”, “an often limited part of a whole” “to make something an integral part of” respectively. Further note the limitation “contact/attach” is being interpreted to include "direct contact/attached" (no intermediate materials, elements or space disposed there between) and "indirect contact/attached" (intermediate materials, elements or space disposed there between). Claim(s) 1, 2, 6 are rejected under 35 U.S.C. 103 as being unpatentable over Kawakita et al (US 2015/0084080 A1 hereinafter Kawakita) in view of Kawakita et al Fig 9 (US 2015/0084080 A1 hereinafter Kawakita9) and further in view of Fagan et al (US 2018/0005847A1 hereinafter Fagan).

References Kawakita and Kawakita9 are analogous art because they both are directed to semiconductor devices and one of ordinary skill in the art would have had a reasonable expectation of success to modify device of Kawakita with the specified features of Kawakita9 because they are from the same field of endeavor. It would have been obvious to one of ordinary skill in the art at the time of effective filing of the invention to combine teachings of Kawakita and Kawakita9 so that a first via extending at least partially through the substrate; a second via extending at least partially through the glass core; a layer extending between and connected to the first via and the second via as taught by Kawakita9 in Kawakita’s device since, having vias in the substrate provides for electrical connection. However, Fagan in a semiconductor device teaches [0021] that ceramic glass and amorphous glass are alternative substrate materials. References Kawakita, Fagan and Kawakita9 are analogous art because they both are directed to semiconductor devices and one of ordinary skill in the art would have had a reasonable expectation of success to modify device of Kawakita and Kawakita9 with the specified features of Fagan because they are from the same field of endeavor. It would have been obvious to one of ordinary skill in the art at the time of effective filing of the invention to combine teachings of Kawakita, Fagan and Kawakita9 so that an amorphous solid glass core as taught by Fagan in Kawakita’s and Kawakita9’s device since, glass-ceramic and glass-amorphous are art recognized equivalents in semiconductor.
