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. Claims 12 and 13 are rejected under 35 U.S.C. 103 as being unpatentable over Yazzie et al (US Publication 20200357752). Regarding claim 12, Yazzie teaches the limitations of claim 11 upon which claim 12 depends. Yazzie teaches further comprising: a bottom housing (Fig. 2B, 210; a printed circuit board disposed in the bottom housing (Fig. 2B, PCB 210), wherein the element is fastened on a side of the printed circuit board facing away from the bottom housing (Fig. 2B, 203 fastened away from 210); a heat dissipation boss disposed on a side of the upper cover closer to the bottom housing (Fig. 2B, 218 on upper part of 216); the elastic structure in the heat dissipation assembly in contact with the heat dissipation boss (Fig. 2B, 218 and 214 in contact with 216 and bent portions of 216), wherein the elastic structure is deformed (Fig. 2B, 216 bent portions deformed when 216 is fastened). The embodiment of Fig. 2A/B does not teach an upper cover fixedly connected to the bottom housing, but the embodiment of Fig 1A/B does (para 21, “backing plate”). It would have been obvious to one of ordinary skill in the art before the effective filing date of the present application for Yazzie to include a cover plate as taught by the embodiment of Fig. 1A and Fig. 1B in order to further improve the reliability and operability of the device. Regarding claim 13, Yazzie teaches the limitations of claim 12 upon which claim 13 depends. Yazzie teaches wherein space between the heat dissipation boss and the heat spreader is filled with a first heat conducting material (Fig. 2B, metal leaf spring 216 between 218 and 214). Response to Arguments Applicant's arguments filed 2 February 2026 have been fully considered but they are not persuasive. Regarding claims 1 and 11, applicant argues that Yazzie does not teach “a frame body configured to limit a position of the heat spreader, wherein the frame body surrounds a side wall of the heat spreader; and an elastic structure fixedly connected to the frame body, wherein the elastic structure is located on a side of the heat spreader facing away from the element" Yazzie teaches a frame body configured to limit a position of the heat spreader (Fig. 2A, frame body is the portion of 216 in contact with heat spreader 214), wherein the frame body surrounds a side wall of the heat spreader (Fig. 2A, frame body portion of 216 surrounds a side wall of heat spreader 214), and an elastic structure fixedly connected to the frame body (Fig. 2A, angled portions of 216 connected on either of frame body portion of 216 in contact with heat spreader 214), wherein the elastic structure is located on a side of the heat spreader facing away from the element (Fig. 2A, angled portion of 216 is located on a side of heat spreader 214 facing away from the element 203). Yazzie element 216 is described as a leaf spring (Yazzie, para 32). Leaf springs are known in the semiconductor industry to be precision manufactured multilayer metal or composite structures designed to bend under pressure acting as flexible connectors or holding mechanisms to fix, secure, or hold elements. The different layers of the leaf spring can be considered the frame body and elastic structure. It is recommended that the applicant consider clarifying that the frame body includes a protrusion structure as stated in paragraphs 11-14 and 76-80 of the instant application. 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.
