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) 5-6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Geng (US 20230301031 A1) alone as applied to claim 4 above. As to claim 5, Geng does not explicitly disclose: wherein the mount comprises an extension extending further into the space, and the board substrate comprises an aperture configured to receive the extension to engage the board substrate with the mount. However, Geng clearly depicts Phillips head fasteners in Fig. 3, which would extend through apertures of the board 331 and thread into the threaded apertures of the mount. 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 Geng, e.g., providing: wherein the mount comprises an extension (Phillips head threaded fastener) extending further into the space, and the board substrate comprises an aperture configured to receive the extension to engage the board substrate with the mount; in order to provide the predictable result of fastening the board substrate to the threaded aperture mounts. 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 6, Geng discloses: wherein the mount comprises an aperture (see raised threaded apertures, Fig. 3). Geng does not explicitly disclose: the board substrate comprises an additional aperture configured to align with the aperture of the mount, and the apparatus comprises a fastener configured to extend into the aperture of the mount and the additional aperture of the board substrate of the control board to engage the board substrate with the mount. However, Geng clearly depicts Phillips head fasteners in Fig. 3, which would extend through apertures of the board 331 and thread into the threaded apertures of the mount. 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 Geng, e.g., providing: the board substrate comprises an additional aperture configured to align with the aperture of the mount, and the apparatus comprises a fastener configured to extend into the aperture of the mount and the additional aperture of the board substrate of the control board to engage the board substrate with the mount; in order to provide the predictable result of fastening the board substrate to the threaded aperture mounts. 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) 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Geng (US 20230301031 A1) as applied to claim 7 above, and further in view of Lo (US 20220225543 A1). As to claim 8, Geng discloses: the control board comprises an interface (see left pin interface, clearly shown) configured to be positioned in the space to couple to the electrical conductor (physically positioned within the space and physically coupled by the board/assembly). Geng does not disclose: wherein the electrical conductor is coiled to define an additional space. However, Lo discloses: wherein the electrical conductor 33 (par. 0040; Fig. 2) is coiled to define an additional space (generally within the loop/coil of 33), in order to connect to the interface/connector 32. 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 Geng as suggested by Lo, e.g., providing: wherein the electrical conductor is coiled to define an additional space; in order to connect to the interface/control board. 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) 21 and 24-25 is/are rejected under 35 U.S.C. 103 as being unpatentable over Geng (US 20230301031 A1) as applied to claims 1 and 14 above, and further in view of Curtis (US 7515413 B1). As to claim 21, Geng does not disclose: a fastener configured to extend through the first panel, the second panel, and the fan. However, Curtis discloses: a fastener 68 (Fig. 2-5) configured to extend through the first panel 70A, the second panel 70B, and the fan 64; in order to fasten the fan to an emi shield 66 (col. 4, lines 52-61). 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 Geng as suggested by Curtis, e.g., providing: a fastener configured to extend through the first panel, the second panel, and the fan; in order to fasten the fan to an emi shield. It has been held that rearranging parts of an invention (e.g., rearranging the positions of panel flanges, mounting apertures, etc.) involves only routine skill in the art. In re Japikse, 86 USPQ 70. 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 24, Geng does not disclose: wherein the fastener is configured to extend through the first panel and the first aperture of the fan to couple the fan to the housing. However, Curtis discloses: a fastener 68 (Fig. 2-5) configured to extend through the first panel 70A, the second panel 70B, and the fan 64; in order to fasten the fan to an emi shield 66 (col. 4, lines 52-61). 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 Geng as suggested by Curtis, e.g., providing: wherein the fastener is configured to extend through the first panel and the first aperture of the fan to couple the fan to the housing; in order to fasten the fan to an emi shield. It has been held that rearranging parts of an invention (e.g., rearranging the positions of panel flanges, mounting apertures, etc.) involves only routine skill in the art. In re Japikse, 86 USPQ 70. 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 25, Geng in view of Curtis discloses: wherein the fastener 68 (Fig. 2-5; Curtis) is configured to extend through the first panel 70A, the first aperture of the fan 64, and an electrical device 66 (emi shield in Fig. 2-5; also extends through portion of electrical device 22 in Fig. 1; Curtis; electrical device in Fig. 1 of Geng is a server, fan assembly and fasteners extend through opening in device when installed) to couple the apparatus to the electrical device. Allowable Subject Matter Claim 19 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: As to claim 19, the allowability resides in the overall structure and functionality of the apparatus as recited in the dependent claim 19, including all of the limitations of their base claims and intervening claims, and at least in part, because they recite the following limitations: 19. (Original) The apparatus of claim 16, wherein the fan comprises an electrical conductor configured to extend around the board substrate and between the wall and the board substrate to couple to the interface, and the control board is configured to control operation of the fan via the electrical conductor. Li (US 8517678 B2), Franz (US 20080239665 A1), and Chen (US 6808411 B2) disclose conventional fan assemblies. None of the prior art, either alone or in combination, can be reasonably construed as adequately teaching the above claimed elements, in combination with the remaining claim limitations.
