4 and 5). The Marto and Lepere article focuses upon pool
boiling heat transfer from machined enhanced surfaces (surface
cavities) to dielectric fluids. The article explains (page
297) that Thermoexcel E surfaces, in particular, exhibit very
little temperature overshoot and hysteresis following surface
aging C and D. Comparison Figures 6 through 8 in the article
(page 296) address data derived for the alternative procedures
of surface aging A, B, C, and D (page 294). The Hesketh
dissertation teaches wafers with a polished side, wherein
microconfigured structures (the hexagonal microcavities of
Figure 2.1; page 44 of the dissertation) are etched into the
polished side using standard photolithography.
Notwithstanding, the clear relevance of the above
reference disclosures to the method of claim 1, akin to the
examiner’s understanding of the evidence of obviousness, we
perceive a lack of indication or suggestion in the applied
prior art for the claimed method feature of the heating of the
surface initiating nucleate boiling of the refrigerant with a
reversal of trend of less than 2°C and without a temperature
overshoot on the initial ascent. Figure 16 graphically
