Office Action

§103 §112
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 . Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the substrate or electronic component including receiving portions and a fastened thickness (claim 1 and 10) and tension contact surface points (claims 2, 3, 11, and 12) must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-18 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1, lines 12-18 and claim 10, lines 13-18 recite “wherein the liquid-cooling heat exchange apparatus includes a first liquid-cooling heat exchange apparatus having a first waterblock set comprising a first block thickness or a second liquid-cooling heat exchange apparatus having a second waterblock set comprising a second block thickness, wherein a thickness of the second block thickness is greater than a thickness of the first block thickness” which is unclear whether the claim requires both the first waterblock set and the second waterblock set or just one of the two. For Examining purposes it will be interpreted as requiring both sets. 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. Claim(s) 1-5, 8-14, 17, 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Fuglsang (European Patent Publication EP3907584A1) in view of Lin (Chinese Patent Publication CN109950217A). Regarding claim 1, Fuglsang discloses a universal mounting mechanism (fig 7A,7B), configured to mount a liquid-cooling heat exchange apparatus to a substrate or an electronic component (¶0039), comprising: a mounting bracket (820), configured for mounting the liquid-cooling heat exchange apparatus to the substrate or the electronic component, the mounting bracket including a mounting flange (see annotated fig 7B below) having an attachment surface (see annotated fig 7B below) and a mounting surface opposite the attachment surface; and a universal mounting mechanism wherein disclose at least one universal fastener assembly (3), orthogonally assembled through the mounting bracket from the attachment surface, wherein the liquid-cooling heat exchange apparatus includes a first liquid-cooling heat exchange apparatus (810) having a first waterblock set (810) comprising a first block thickness (see annotated fig 7B below) or a second liquid-cooling heat exchange apparatus having a second waterblock set (840) comprising a second block thickness (see annotated fig 7B below), wherein a thickness of the second block thickness is greater than a thickness of the first block thickness.

Fuglsang further discloses wherein the liquid-cooling heat exchange apparatus further comprises a liquid pump module (2) disposed on the waterblock set (810), controlling the liquid-cooling heat exchange apparatus, the liquid pump module including an inlet (5) and an outlet (4), and the waterblock set further comprises a heat exchange chamber (for 840) and a surface (812), wherein the surface is configured to dissipate heat from heat generating sources, whereby via the inlet and outlet, the liquid pump module circulates fluid within the heat exchange chamber for cooling the heat generating sources (fig 7B). Claims 6, 7, 15, and 16 objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: The prior art does not teach the limitations of claims 6 and 15. Specifically, the limitations “a pair of alignment prongs protruding outwardly from the mounting surface, each of the pair of alignment prongs including a proximal portion, a distal portion, and at least one tightening rail, the proximal portion protruding outwardly from the mounting surface, the at least one tightening rail protruding longitudinally along the proximal portion, and the distal portion connected to the proximal portion, and a diameter of the proximal portion is greater than a diameter of the distal portion” are not taught. Lin, considered the closest prior art, teaches providing a pair of alignment prongs (213). However, Lin fails to teach a distal portion connected to the proximal portion, and a diameter of the proximal portion is greater than a diameter of the distal portion as the alignment prongs are not circular. The prior art fails to render this obvious and thus the claims contain allowable subject matter.
