Appeal No. 94-1325
Application No. 07/882,928
that relies upon the laser technique of Gnanamuthu. However, based
in particular upon the statements of declarant Seguin and the
present
specification, we are persuaded that the limitations in claim 5,
as specified above, would not have been suggested by the applied
prior art.
Declarant Seguin states (declaration, paragraph 6)
For the generation of a vapour
space, 2000 kWatts per sq. cm.
are required as a minimum. As
cited in the present application
(page 8, lines 8 - 16), the
required power density is in the
order of several thousand kWatts
per sq. cm.
The specification (page 8, lines 8 through 12) sets
forth that
Specifically, above a specific
laser power density threshold of
several million watts per square
centimeter, the beam intensity
is sufficient to create and
maintain a small diameter
opening or hole, extending a
very large distance below the
surface.
