Office Action

§103
amezNotice 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 . Specification The specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification. Election/Restrictions Claims #17-19, 27 are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 07/09/2026. Applicant Argues that, ‘In view of the above, Applicants submit that the search and examination of all the alleged Groups (e.g., Groups I through Group III) may be made without serious burden. Accordingly, Applicants respectfully request the Examiner to reconsider and withdraw the above requirement(s). The Examiner has considered the Applicant’s arguments, but respectfully disagrees. The Examiner has considered the Applicants arguments, but respectfully disagrees. As shown in the restriction request issue on 07/08/26, Groups I, II and III represent different package structures; see previous restriction requirement for specific details. The Examiner further directs the Applicant to MPEP 35 U.S.C. 121, where a quote in the preceding section states that the Director may require restriction if two or more "independent and distinct" inventions that are claimed in one application. Furthermore, in 37 CFR 1.141, the statement is made that two or more "independent and distinct inventions" may not be claimed in one application. Because the Examiner has demonstrated in the previous restriction that Groups I, II and III have different structures that are not mutually shared, the Examiner takes the position that they represent different inventive entities; i.e. and therefore should be restricted. For these reasons, the Examiner takes the position that the restriction was proper and maintains his position. For the above explained reasons, the Examiner maintains his position and therefore the restriction requirement is made final. Claims #1-16 will be further Examined. Information Disclosure Statement The information disclosure statement (IDS) submitted on 06/05/24 was filed in a timely manner; thus, the submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. 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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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. Claim #1, 2, 5-7, 9-15 are rejected under 35 U.S.C. 103 as being unpatentable over Mao et al., (U.S. Pub. No, 2023/0343749), hereinafter referred to as "Mao" and in view of Lee et al., (U.S. Pub.

The Examiner notes that, with respect to claim #14, Mao doses not explicitly state the presents of a fourth stack. However, the Examiner takes the position that Mao shows a process wherein multiple stacks may be added (paragraph 0015, 0025) and furthermore states that the process is yields non-limiting embodiments (abstract, paragraph 0003, 0010). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to continuously add additional stacks to fulfill the design needs of the device, since it has-been held that mere duplication of the essential working parts of a device involves only routine skill in the art. St. Regis Paper Co. v. Bemis Co., 193 USPQ 8. Furthermore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention, with respect to claim #14, to modified the invention of Mao as modified by the invention of Lee , which teaches, a semiconductor package a fourth semiconductor chip stacked on the third semiconductor chip to cover the third sub-chip pads, to incorporate a structural condition that would large amount of electrical connections to various devices, as taught by Lee.

No, 2023/0343749), hereinafter referred to as "Mao" as modified by Lee et al., (U.S. Pub. No. 2017/0358564), hereinafter referred to as "Lee" as shown in the rejection of claim #7 above and in further view of Chiu et al., (U.S. Pub. No. 2018/0005974), hereinafter referred to as "Chiu". Mao as modified by Lee, substantially shows the claimed invention as shown in the rejection of claim #7 above. Mao as modified by Lee, fails to show, with respect to claim #8, semiconductor package wherein the second sub-chip pads are configured to transmit a power signal or a ground signal to the package substrate through the third conductive wires. Chiu teaches, with respect to claim #8, a semiconductor package wherein the second sub-chip pads are configured to transmit a power signal or a ground signal to the package substrate through the third conductive wires (paragraph 0050, 0058).

No, 2023/0343749), hereinafter referred to as "Mao" as modified by Lee et al., (U.S. Pub. No. 2017/0358564), hereinafter referred to as "Lee" as shown in the rejection of claim #15 above and in further view of Chiu et al., (U.S. Pub. No. 2018/0005974), hereinafter referred to as "Chiu". Mao as modified by Lee, substantially shows the claimed invention as shown in the rejection of claim #15 above. Mao as modified by Lee, fails to show, with respect to claim #16, semiconductor package wherein the third and fourth chip pads and the fourth sub-chip pads are configured to receive a power signal or a ground signal from the package substrate through the fourth to sixth conductive wires. Chiu teaches, with respect to claim #16, a semiconductor package wherein the third and fourth chip pads and the fourth sub-chip pads are configured to receive a power signal or a ground signal from the package substrate through the fourth to sixth conductive wires (paragraph 0050, 0058). The Examiner notes that, with respect to claim #16, Mao doses not explicitly state the presents of fourth to sixth conductive wires. However, the Examiner takes the position that Mao shows a process wherein multiple stacks wherein any pads may be wire connect to any chosen pad location (paragraph 0015, 0025) and furthermore states that the process is yields non-limiting embodiments (abstract, paragraph 0003, 0010). It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to continuously add additional stacks to fulfill the design needs of the device, since it has-been held that mere duplication of the essential working parts of a device involves only routine skill in the art. St. Regis Paper Co. v. Bemis Co., 193 USPQ 8.

EXAMINATION NOTE The rejections above rely on the references for all the teachings expressed in the text of the references and/or one of ordinary skill in the art would have reasonably understood or implied from the texts of the references. To emphasize certain aspects of the prior art, only specific portions of the texts have been pointed out. Each reference as a whole should be reviewed in responding to the rejection, since other sections of the same reference and/or various combinations of the cited references may be relied on in future rejections in view of amendments.
