surface."
Appellants' specification (page 9, lines 11-14; page 10,
lines 6-22; page 11, lines 3-14) describes a number of
specific factors, e.g. the shape and dimensions of the prongs,
which are determinative in obtaining this desired effect as
claimed. The examiner offers no convincing reason, nor are we
aware of any, why the prongs or fingers described and depicted
in the cited references would necessarily produce the outcome
required by the instant claims even if used in the particular
context of back-etching tungsten-coated substrate surfaces.
To wit, Cheng et al. is silent with regard to the dimensions
of radial fingers 78 F. Thus, it would be sheer speculation
to postulate that the fingers depicted in Cheng et al. would
necessarily function as claimed. Similarly, it would be sheer
speculation to postulate that the fingers depicted in Turner
et al. would necessarily function as claimed since Turner et
al., like Cheng et al., fail to recognize or disclose any
critical interrelationship between the shape and dimensions of
the fingers which would necessarily result in their being
