Appeal No. 1998-2376 Page 9
Application No. 08/400,325
rejection of claims 2, 5, and 6 obvious over Lipscomb in view
of Griffin further in view of Brennan.
Claim 7 recite a process. The claim specifies in
pertinent part the following limitations: "extruding a unitary
housing structure including a sidewall portion, a central
housing structure, and a baffle plate interconnecting said
sidewall portion and central housing structure ...."
As aforementioned, the examiner admits that Lipscomb's
side angle plate, integral center panel, and cellular lattice
are not extruded. Because Griffin teaches extruding only a
housing formed with a back wall and oppositely disposed side
walls, we are not persuaded that teachings from the prior art
would have suggested the limitations of "extruding a unitary
housing structure including a sidewall portion, a central
housing structure, and a baffle plate interconnecting said
sidewall portion and central housing structure ...."
Therefore, we reverse the rejection of claim 7 as obvious over
Lipscomb in view of Griffin further in view of Brennan.
