through the cooling screens (see column 1, lines 56-66).
Absent the appellants’ own disclosure, we are at a complete
loss to understand why one of ordinary skill in this art would
have been motivated to single out a plenum from the gas
generator of Jorgensen (wherein the flow of gas is
circumferential through the cooling screens) and incorporate
it into the gas generator of Goetz (wherein the flow of gas
through the cooling screens is radial).
Moreover, even if the teachings of Goetz and Jorgensen
were combined in the manner proposed by the examiner, the
claimed invention would not result. Recognizing that Goetz
does not teach a plenum, the examiner apparently proposes to
single out from Jorgensen’s gas generator either the plenum 4’
or the plenum or recess in which neutralizing packages 21 are
contained. If plenum 4’ is singled out, this plenum (which
contains no screen) lies between Jorgensen’s generator housing
22 and baffle enclosure 12’ whereas each of the independent
claims on appeal expressly require (1) the plenum to be
between the baffle enclosure and the propellant container and
(2) a final coolant screen to be disposed between the baffle
enclosure and the generator housing. Alternatively, if one of
