Office Action

§102 §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 . 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. Claim 1 is 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 recites the limitation "the printed circuit board assembly" in line 1 and “the system motherboard and the other components” in lines 5-6. There is insufficient antecedent basis for these limitations in the claim. 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. Claims 1-3, 5-9, 11-13 and 15-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Nakajima (US 5715139 A).

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. Claims 4 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Nakajima (US 5715139 A) as applied to claims 1 and 11 above, and further in view of Smith (US 20070247800 A1). As to Claims 4 and 14, Nakajima does not disclose: wherein the mounting components are snap fit connectors. However, Smith discloses: wherein the mounting components are snap fit connectors (Par. 0232 “the main faceplate 955 is removably attached to the front 961 in a snap-fit fashion. It should be appreciated, however, that main faceplate 955 can be removably attached to the front 961 through the use of any suitable fastener, including, but not limited to, hook and loop fasteners, snaps and screws”); in order to provide detachably/removable connect the face plate to the front (Par. 0232). It would have been obvious to one of ordinary skill in the related art(s) before the effective filing date of the claimed invention to modify the device of Nakajima as further suggested by Smith e.g., providing: wherein the mounting components are snap fit connectors; in order to provide detachable/removable connect between the frame and information handling system. Additionally, all claimed elements were known in the prior art and one skilled in the art could have combined/modified the elements as claimed by known methods with no change in their respective functions, and the combination/modification would have yielded predictable results to one of ordinary skill in the art before the effective filing date of the claimed invention. See KSR International Co. v. Teleflex Inc., 550 U.S.___, 82 USPQ2d 1385 (2007). Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Nakajima (US 5715139 A) as applied to claim 1 above, and further in view of Takakusaki (US 20090073655 A1). As to Claim 10, Nakajima does not disclose: further comprising: a heat sink plate, a plurality of heat pipes, and a plurality of heat sinks. However, Takakusaki discloses: further comprising: a heat sink plate (first heat-receiving plate 52; see Figs. 3 and 8), a plurality of heat pipes (heat pipes 54 and 64), and a plurality of heat sinks (first and second radiating fins 53, 63); in order to provide a heat radiating mechanism to cool first and second chips within a portable computer (Par. 0056). It would have been obvious to one of ordinary skill in the related art(s) before the effective filing date of the claimed invention to modify the device of Nakajima as further suggested by Takakusaki e.g., providing: further comprising: a heat sink plate, a plurality of heat pipes, and a plurality of heat sinks; in order to provide a heat radiating mechanism to cool components within a portable computer. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Yoo (US 20220069437 A1) discloses a laptop with internal cooling structures. Bondi (US 20260010198 A1) discloses a frame holding a circuit board and cooling structures. Hirai (US 20150103501 A1) discloses a laptop with a cooling structure and internal frame.
