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. Claims 5, 11, and 17 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. Claims 5, 11, and 17 requires “the top wall being positioned to be contiguous with a top panel of an information handling system chassis when the fan system gantry component is mounted within the information handling system chassis” it is unclear if this limitation is positively claimed or intended use because it refers to a previously unclaimed system produced by the combination of the fan gantry and an information handling system chassis. For the purposes of examination the claim is interpreted as intended use, where the contiguity between the fan gantry system and the top panel of the information handling system would depend on which information handling system the fan gantry is installed in, where a person having ordinary skill in the art could install the fan gantry in an information handling system such that the top wall of the fan gantry is contiguous with the top panel of the information handling system. 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. Claim(s) 1, 3 and 5-6 is/are rejected under 35 U.S.C. 102(a)(1) as being Yin et. al (US 8,075,248 B2).

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 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(s) 2, 8, and 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yin et. al (US 8,075,248 B2) in view of Tan (US 8,300,404 B2). With respect to claims 2, 8, and 14 Yin does not disclose that the bottom wall defines a plurality of fan connector apertures, each of the plurality of fan connector apertures being positioned to receive a respective fan connection component, each fan system connection component being coupled to a respective fan of the plurality of fans. Tan discloses a fan gantry [reference character 100] including a bottom wall [see annotated Fig. below] where the bottom wall defines a plurality of apertures [see annotated Fig. below] positioned to receive a respective fan connection component [reference character 132], each fan system connection component being coupled to a respective fan of the plurality of fans. In Tan the fan connection components extend through the bottom wall so that the fans installed in the gantry can easily interface with the system board fan connectors [reference character 134]. It would have been obvious to one of ordinary skill in the art at the time of the filing date of the invention to modify the gantry taught by Yin by including apertures in the bottom wall as taught by Tan so that respective fan connection components can easily interface with their corresponding system board fan connectors. Claim(s) 4, 10, and 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yin et. al (US 8,075,248 B2) in view of Gopalakrishna et. al (US 10,485,136 B2). With respect to claims 4, 10, and 16 Yin discloses a right inside wall [see annotated Fig. below] physically attached to the bottom wall, the right inside wall extending substantially perpendicularly from the bottom wall; and, a left inside wall [see annotated Fig. below] physically attached to the bottom wall, the left inside wall extending substantially perpendicularly from the bottom wall. Yin does not disclose that the right inside wall and the left inside wall define a slot of a cable routing portion. Gopalakrishna discloses a fan gantry component [reference character 206] which includes inside walls [reference character 216b in Fig. 4A.] that define a slot [reference character 228 in Fig. 4B] which “…provides a path for electrical components (e.g., cables and bus bars) underneath the fan cage assembly 206 to increase design flexibility for routing various electrical components” [column 3 lines 23-25]. It would have been obvious to one of ordinary skill in the art at the time of the filing date of the invention to modify the fan gantry taught by Yin by forming slots in the left and right inner walls, as taught by Gopalakrishna, in order to “…provides a path for electrical components (e.g., cables and bus bars) underneath the fan cage assembly 206 to increase design flexibility for routing various electrical components” [column 3 lines 23-25 of Gopalakrishna].
