at column 2, lines 11-14, namely, "intensity of a given wave-
length radiated by a black-body is a function of the temperature,
and it is this temperature which also will determine the
efficiency of selective line emitters." However, the examiner
has not explained how, if the efficiency of a selective line
emitter is dependent upon the temperature, one of ordinary skill
in the art would have reasonably expected that a selective line
emitter would have sufficient efficiency over a range of
temperatures such that it can function in an optical temperature
sensor. We note that Rose also teaches that "the intensity at a
particular wavelength is exponential in temperature which should
result in a strong temperature dependence for line emission"
(column 2, lines 18 and 19). Rose further discloses that "[a]t
short wavelengths, in the ultraviolet region of their spectrum,
these rare oxides tend to have high emissivity, but these modes
are only excited efficiently at extremely high temperature"
(column 2, lines 25-28). Rose even further discloses that
"[s]ince the efficiency of various emitters varies with
temperature, it follows that the nature of the structure-forming
fiber may depend on the particular rare earth metal compound in
the composite and the temperature at which the composite is
contemplated to be used" (column 7, lines 58-62). As urged by
