With respect to Claim 13, Gates further teaches (in Figure 1 and as shown in annotated Figure 1 above)
wherein said heat pipe (46) is vertically oriented within said container (see annotated Figure 1 above).
With respect to Claim 16, Gates further teaches (in Figure 1 and as shown in annotated Figure 1 above)
A method comprising the steps of:

Components in the external enclosure are thus cooled by thermal conduction to and through the walls 16 and 24 of the external enclosure 2 and by natural convection over the extended surfaces 40. Some components e.g. power transistors 44 generate such large amounts of heat that the cooling already described may be insufficient. Such local hot spots are cooled by heat pipes 46.

the steps of: providing an air mover (58, column 3, lines 17-20); and exchanging air from inside of the exterior enclosure (28) with air from outside of the exterior enclosure (28). (See annotated Figure 1 above, the fan (58) would create air flow through the vents and openings 30 & 38)
Claim Rejections - 35 USC § 103
In the event 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 (i.e., changing from AIA to pre-AIA ) 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.
Claims 7-8, 14 are rejected under 35 U.S.C. 103 as being unpatentable over Gates in view of Cosley et al. (US 7,505,269 - hereinafter, "Cosley").
With respect to Claim 7, Gates teaches the limitations of Claim 1 as per above but fails to specifically teach or suggest the limitations of Claim 7.
Cosley, however, teaches (in column 4, lines 58-61, in Figure 3 and as shown in annotated Figure 3 below)
wherein:
an exterior enclosure (16) has an inside;
a shell of insulation (66) is on an inside of said exterior enclosure (16); and
an air gap containing air (see annotated Figure 3 below) is between said shell of insulation (66) and an interior enclosure (18).
It would have been obvious to a person having ordinary skill in the art at the time before effective filing date of the claimed invention, to combine the teachings of Cosley with Gates, such that an exterior enclosure has an inside; a shell of insulation is on an inside of said exterior enclosure; and an air gap containing air is between said shell of insulation and an interior enclosure as taught by Cosley, since doing so would reduce solar gain into the exterior enclosure. (in column 4, lines 52-54)
With respect to Claim 8, Gates as modified by Cosley teaches the limitations of claim 7 as per above and Gates further teaches (in Figure 1 and as shown in annotated Figure 1 above)
Wherein said air (see annotated Figure 3 below as taught by Cosley in Claim 7 as per above) contained within said air gap (see annotated Figure 3 below as taught by Cosley in Claim 7 as per above) can be exchanged with outside air (see annotated Figure 3 below as taught by Cosley in Claim 7 as per above).

With respect to claim 14, Gates teaches the limitations of Claim 11 as per above but fails to specifically teach or suggest the limitations of Claim 14.
Cosley, however, teaches (in column 4, lines 58-61, in Figure 3 and as shown in annotated Figure 3 above)
wherein:
an exterior enclosure (16) has an inside;
a shell of insulation (66) is on an inside of said exterior enclosure (16);
an air gap (see annotated Figure 3 above) containing air (see annotated Figure 3 above) is between said shell of insulation (66) and an interior enclosure (18), wherein said air (see annotated Figure 3 above) contained within said air gap (see annotated Figure 3 above) can be exchanged with outside air (see annotated Figure 3 above).
It would have been obvious to a person having ordinary skill in the art at the time before effective filing date of the claimed invention, to combine the teachings of Cosley with Gates, such that an exterior enclosure has an inside; a shell of insulation is on an inside of said exterior enclosure; an air gap containing air is between said shell of insulation and an interior enclosure, wherein said air contained within said air gap can be exchanged with outside air as taught by Cosley, since doing so would reduce the solar gain into the exterior enclosure. (in column 4, lines 52-54)
Claims 10, 15, 20 are rejected under 35 U.S.C. 103 as being unpatentable over Gates in view of Fischer et al. (US 7,535,716 - hereinafter, "Fischer").
With respect to Claim 10, Gates teaches the limitations of Claim 1 as per above but fails to specifically teach or suggest the limitations of Claim 10.
Fischer, however, teaches (in column 3, lines 58-65, in figure 4C and as shown in annotated Figure 4C below)
an out-gas vent (158) on an enclosure (100).
It would have been obvious to a person having ordinary skill in the art at the time before effective filing date of the claimed invention, to combine the teachings of Fischer with that of Gates, such that the internal enclosure of Gates includes an out-gas vent, as taught by Fischer, since doing so would guard against excessive external-to-internal pressure difference within the interior enclosure (in column 3, lines 58-65).

Figure IV
With respect to Claim 15, Gates teaches the limitations of Claim 11 as per above but fails to specifically teach or suggest the limitations of Claim 15.
Fischer, however, teaches (in column 3, lines 58-65, in figure 4C and as shown in annotated Figure 4C above)
an out-gas vent (158) on an enclosure (100).
It would have been obvious to a person having ordinary skill in the art at the time before effective filing date of the claimed invention, to combine the teachings of Fischer with that of Gates, such that the internal enclosure of Gates includes an out-gas vent, as taught by Fischer, since doing so would guard against excessive external-to-internal pressure difference within the interior enclosure (in column 3, lines 58-65).
With respect to Claim 20, Gates teaches the limitations of Claim 16 as per above but fails to specifically teach or suggest the limitations of Claim 20.
Fischer, however, teaches (in column 3, lines 58-65, in figure 4C and as shown in annotated Figure 4C above)
wherein the step of providing a container (see Gates’ annotated Figure 1 above) further comprises the step of providing an outgas vent (158) on an enclosure (100).
It would have been obvious to a person having ordinary skill in the art at the time before effective filing date of the claimed invention, to combine the teachings of Fischer with that of Gates, such that the internal enclosure of Gates includes an out-gas vent, as taught by Fischer, since doing so would guard against excessive external-to-internal pressure difference within the interior enclosure (in column 3, lines 58-65).
Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Gates in view of Tikka (US 2001/0052412 - hereinafter, "Tikka").
With respect to Claim 9, Gates teaches the limitations of Claim 1 as per above but fails to specifically teach or suggest the limitations of Claim 9.
Tikka, however, teaches (in paragraph [0019], first sentence) a container which is operational between -80 degrees Fahrenheit and 130 degrees Fahrenheit (in paragraph [0019], first sentence, “The same equipment cabinet is designed to operate both at the normal operating temperature range of -33.degree. C. to +40.degree. C. and the high outdoor temperature range of +40.degree. C. to +50.degree. C.”).
It would have been obvious to a person having ordinary skill in the art at the time before effective filing date of the claimed invention, to combine the teachings of Tikka with that of Gates, such that the container of Gates has an operational temperature between -80 degrees Fahrenheit and 130 degrees Fahrenheit, as taught by Tikka, since doing so would allow for a container which can be used at a variety of operational temperatures.
