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 Objections Claims 2 and 10 objected to because of the following informalities: Claim 2 recites “CRPS/MCRPS” without spelling out the acronym. Claim 10 now depends from claim 8, and repeats “the shelf casing comprises a rear wall disposed in a back side thereof”, which is already recited in parent claim 8. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-15 rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claims 1 and 12 recite “wherein the filling component module … has uniform density”, which constitutes new matter, because it is not supported in the originally filed disclosure. Applicant has suggested that Fig. 5 provides support for the claimed feature, but Fig. 5 depicts the filling component modules only schematically. The specification describes materials, e.g., “the filling component module 6 comprises a waterproof foam, a plastic injection molding or a metal structure” (par. 0033), and does not comment on the uniformity or density of the modules, which raises doubt that the inventor(s), at the time the application was filed, had possession of the claimed invention. 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, 8, 10, 12, and 14 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Fujiwara (US 20190281727 A1).

As to claim 8, Fujiwara discloses: wherein the filling component module 30 comprises a filling component 30, the shelf casing comprises a rear wall (bottom wall in Fig. 2-3) disposed in a back side thereof (bottom side in Fig. 2-3), the filling component 30 is disposed on the rear wall of the shelf casing (see Fig. 4), and the filling component comprises a first installation hole (see four corner holes, see also coolant holes 35). As to claim 10, Fujiwara discloses: wherein the filling component 30 comprises a first liquid channel 35, the shelf casing comprises a rear wall disposed in a back side (bottom wall, bottom side in Fig. 2-3) thereof, the rear wall of the shelf casing comprises a second liquid channel (between inlet 23 and outlet 24; par. 0044), the second liquid channel of the rear wall is in communication with the first liquid channel of the filling component, so that a liquid passes through the first liquid channel and the second liquid channel (see Fig. 2, 6, 7, and 9). As to claim 12, Fujiwara discloses: A power system(Fig. 1-9), comprising: a cooling slot (within 10) comprising a cooling liquid 40; and a plurality of electronic devices (at least two; par. 0040) immersed in the cooling liquid and arranged in sequence, wherein each of the plurality of electronic devices comprises: a shelf casing 20 comprising a plurality of side walls disposed around in sequence; and a filling component module 17, 30 disposed on the exterior of the shelf casing and adjacent to at least one of the plurality of side walls for limiting a flowing direction of the cooling liquid, wherein the filling component module adjacent to at least one of the plurality of side walls has uniform density (fixed portions 17 are depicted as uniform blocks, par. 0043; block 30 is formed of resin and will have a uniform density throughout the material of the block; par. 0030). As to claim 14, Fujiwara discloses: wherein the power system comprises at least one system filling component 13, 15 (Fig. 2) disposed between any one of the plurality of electronic devices and a side wall of the cooling slot. 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) 2-3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Fujiwara (US 20190281727 A1) as applied to claim 1 above, and further in view of Hashimoto (US 20230042343 A1). As to claim 2, Fujiwara does not disclose: wherein the electronic device is an industrial electronic device, wherein the industrial electronic device is a CRPS/MCRPS power device, an industrial power device, a server power device, a server or a networking device.

However, Hashimoto discloses: wherein the electronic device (Fig. 4) comprises a first side frame module 90A and a second side frame module 90B, the first side frame module is disposed on the exterior of the shelf casing (of 32) and attached on the first side wall (left) of the shelf casing, the first side frame module comprises an accommodation space (between rails 94), the second side frame module is disposed on the exterior of the shelf casing and attached on the second side wall (right) of the shelf casing, and the second side frame module comprises an accommodation space (between rails 94; par. 0056); in order to house the electronic devices 32 in their respective slots 30 (par. 0057) and fix them in position (via 100; par. 0058, Fig. 5). 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 Fujiwara as suggested by Hashimoto, e.g., providing: wherein the electronic device comprises a first side frame module and a second side frame module, the first side frame module is disposed on the exterior of the shelf casing and attached on the first side wall of the shelf casing, the first side frame module comprises an accommodation space, the second side frame module is disposed on the exterior of the shelf casing and attached on the second side wall of the shelf casing, and the second side frame module comprises an accommodation space; in order to house the electronic devices in their respective slots and fix them in position. 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(s) 11, 13, and 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Fujiwara (US 20190281727 A1) as applied to claims 1 and 12 above, and further in view of Keehn (US 20230217626 A1). As to claim 11, Fujiwara does not disclose: wherein the filling component module comprises a waterproof foam, a plastic injection molding or a metal structure. However, Keehn discloses: wherein the filling component module comprises a plastic injection molding (par. 0039); in order to provide a lightweight/low density filling component (par. 0039); or a metal structure (par. 0039); in order to provide a heavyweight/high density filling component (par. 0039). 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 Fujiwara as suggested by Keehn, e.g., providing: wherein the filling component module comprises a plastic injection molding or a metal structure; in order to provide a lightweight/low density filling component or a heavyweight/high density filling component. It has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. 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). As to claim 13, Fujiwara does not disclose: wherein the power system comprises at least one system filling component disposed between any two adjacent electronic devices of the plurality of electronic devices.
