Office Action

§102
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 . Response to Arguments and Claim Amendments Applicant’s arguments, see Page 8 of “Applicant Arguments/Remarks Made in an Amendment”, filed 03/10/2026, with respect to the 35 U.S.C. 112(b) rejections of claims 2 and 13 have been fully considered and are persuasive. Claim 2 was canceled which makes the previous rejection no longer needed. Claim 13 was amended to remove/replace the word “proximate,” and in doing so, definitiveness issues have been cleared up. The 35 U.S.C. 112(b) rejections of claims 2 and 13 has been withdrawn. Applicant's arguments filed 03/10/2026 have been fully considered but they are not persuasive. Independent claims 1 and 10 have been amended to include the limitation that the stiffener when in a plan view has a “a top portion, a bottom portion, a first side portion, and a second side portion,” and “in the plan view, and the plurality of slots comprising first slots along the top portion, second slots along the bottom portion, third slots along the first side portion, and fourth slots along the second side portion in the plan view.” The claim(s) amendment does positively add limitations to the claims; however, the new limitations still fail to overcome the previously cited art of Shim or Zhao, Figures shown below. PNG media_image1.png 582 1256 media_image1.png Greyscale Figure 1: Fig. 10 from Shim, and Fig. 13 from Zhao Both Shim and Zhao can appear to contain a stiffener, where the plan view (As displayed above) has a “a top portion, a bottom portion, a first side portion, and a second side portion.” Where each of the portions, can at least be understood at least to be a peripheral edge and the immediate area next to said edge. Furthermore, each portion (top/bottom/side) also must have some plurality of slots along said portion. However, under broadest reasonable interpretation, both of the references appear to disclose this as well. As an example, please see annotated Fig. 10 from the Shim reference. PNG media_image2.png 438 578 media_image2.png Greyscale Figure 2: Annotated Fig. 10 from Shim. One thing to notice is that some of the slots are shared between portions, however, there is nothing within the claim(s) which makes this problematic. Only that the portion has a plurality of slots that is different from the plurality of slots of a different portion. Even with shared slots, as long as it is not exactly the same plurality of slots, the pluralities of slots will be different. E.g. the above annotated figure shows that the “plurality of slots” from the top portion and the “plurality of slots” from the side portion are different pluralities, even with the overlapping slot. Its for these reasons that even with the additional limitations to the claims in the amendment, that the recited prior art still discloses the instant application. Claim Rejections - 35 USC § 102 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1, 3-4, 9-13 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by United States Patent Application Publication by Shim (US 20090115048 A1; Shim). Regarding claim 1, Shim discloses an apparatus comprising: a stiffener (150/250/350) for a semiconductor substrate (120), the stiffener having a first side and a second side opposite the first side in a cross-sectional view (The stiffener is plate like, we will say the large flat sides of the plates are the first and second sides), and the stiffener having a top portion, a bottom portion, a first side portion, and a second side portion in a plan view. (Fig. 10, where each of the edges along with the direct adjacent area can be considered the different portions with the top being the top portion and so on); and a plurality of slots in the stiffener (154/254/354), each of the plurality of slots extending from the first side of the stiffener to the second side of the stiffener in the cross-sectional view (Figures 4 and 7, showing that the slots 154 are extending through the entirety of the stiffener from the first side to the second side), and the plurality of slots comprising first slots along the top portion, second slots along the bottom portion, third slots along the first side portion, and fourth slots along the second side portion in the plan view (See annotated Fig. 10 below, where each portion will have a plurality of slots and said pluralities will be different from each other).
