Office Action

§102 §103
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 . DETAILED ACTION Claim Rejections - 35 USC § 102 1. In the event that 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 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 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) 1-6, 14-16 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chen et al. US2007/0235168. Per claim 1 Chen et al. teaches a system (see fig.4) comprising: an electronic equipment housing (200, see fig.4) having a first heat generating device (30, see fig.4) therein; a fan (50) configured to induce air flow through the housing (see fig.4; [0019], [0028]); a first heat sink thermally coupled to the first heat generating device (see fig.4; [0028]); and a first diverter (10, see fig.1) positioned to direct at least a first portion of the air flow into the first heat sink (see fig.4). Per claim 2 Chen et al. teaches the system of claim 1, further comprising a second heat generating device (30, see fig.4) within the housing and a second heat sink thermally coupled to the second heat generating device (see fig.4), and wherein the first diverter is configured to also direct at least a second portion of the air flow into the second heat sink (see fig.4). Per claim 3 Chen et al. teaches the system of claim 2, wherein the first diverter is V-shaped (see fig.1 & 4-5; [0026]). Per claim 4 Chen et al. teaches the system of claim 2, wherein the first diverter has a V-shaped cross-section (see fig.1 & 4-5; [0026]). Per claim 5 Chen et al. teaches the system of claim 2, wherein the first diverter is vertically oriented (see fig.1 & 4-5). Per claim 6 Chen et al. teaches the system of claim 2, wherein the first diverter is oriented at a first angle with respect to a vertical axis (see fig.4-5). Per claim 14 Chen et al. teaches the system of claim 1, further comprising a second heat sink thermally coupled to the first heat generating device (30; [0019] & [0028], see fig.4, “All the components are thermally coupled via the circuit board and chassis to the four heat sinks”). Per claim 15 Chen et al. teaches the system of claim 14, further comprising a second heat generating device (30) within the housing, a third heat sink thermally coupled to the second heat generating device, and a fourth heat sink thermally coupled to the second heat generating device (30; [0019], [0028], see fig.4, “All the components are thermally coupled via the circuit board and chassis to the four heat sinks”). Per claim 16 Chen et al. teaches the system of claim 15, wherein the first diverter (10) is configured to also direct at least a second portion of the air flow into the third heat sink (see fig.4). Claim(s) 1-2 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Gedamu et al. US2005/0047105. Per claim 1 Gedamu et al. teaches a system (see fig.7) comprising: an electronic equipment housing (C, see fig.7; [0025]) having a first heat generating device (P, see fig.7; [0017], “Top P”) therein; a fan (702) configured to induce air flow through the housing (see fig.7; [0025]); a first heat sink (102, see fig.1-2 & 7) thermally coupled to the first heat generating device (P, see fig.1-7; [0017]-[0019]); and a first diverter (704, see fig.7) positioned to direct at least a first portion of the air flow into the first heat sink (see fig.7). Per claim 2 Gedamu et al. teaches the system of claim 1, further comprising a second heat generating device (P, see fig.7, “bottom P”) within the housing and a second heat sink (102, see fig.1-7, “bottom 102”; [0024]-[0025]) thermally coupled to the second heat generating device (see fig.7), and wherein the first diverter is configured to also direct at least a second portion of the air flow into the second heat sink (see fig.4). Claim Rejections - 35 USC § 103 2. In the event that 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 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. Claim(s) 7-8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chen et al. US2007/0235168. Per claim 7 Chen et al. discloses substantially all the limitations of the claim(s) except for the system of claim 2, wherein the first diverter is horizontally oriented. It would have been an obvious matter of design choice before the effective filing date of the claimed invention to a person having ordinary skill in the art to make the diverter horizontally oriented, because it enables a diverted flow of air in an horizontal orientation, since it has been held that rearranging parts of an invention involves only routine skill in the art. In re Japikse, 86 USPQ 70. Per claim 8 Chen et al. discloses substantially all the limitations of the claim(s) except for the system of claim 2, wherein the first diverter is oriented at a first angle with respect to a horizontal axis. It would have been an obvious matter of design choice before the effective filing date of the claimed invention to a person having ordinary skill in the art to make the diverter horizontally oriented at a first angle with respect to a horizontal axis, because it enables a diverted flow of air in an horizontal orientation, since it has been held that rearranging parts of an invention involves only routine skill in the art. In re Japikse, 86 USPQ 70. Allowable Subject matter 3. Claims 9-13 & 17-20 are 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. Claim 9, includes allowable subject matter because of the system of claim 2, further comprising a second diverter positioned between the first heat sink and the second heat sink. Per claim 10-13, depends on claim 9 therefore allowable for the same reason. Claim 17 includes allowable subject matter because of the system of claim 16, further comprising a second diverter configured to direct at least a third portion of the air flow into the second heat sink. Per claim 18 & 20, depends on claim 17 therefore allowable for the same reason. Claim 19 includes allowable subject matter because of the system of claim 16, further comprising a second diverter positioned between the first heat sink and the third heat sink. Email Communication 4. Applicant is encouraged to authorize the Examiner to communicate via email by filing form PTO/SB/439 either via USPS, Central Fax, or EFS-Web. See MPEP 502.01, 502, 502.05. Conclusion 5. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Hernon US2010/0302730 discloses a heat dissipation apparatus, comprising: a heat sink that is adapted to receive a processor mounted thereto, the heat sink comprising an internal chamber that is adapted to receive a fluid flow that removes heat from the heat sink. Andersen US20240130072 discloses an airflow guide, comprising: at least one first channel configured to direct a portion of air from a first fan in a first direction; and at least one second channel configured to direct a portion of air from a second fan in a second direction.
