Appeal No. 2003-0639
Application No. 09/839,766
As recognized by the examiner, none of the applied
references discloses applying adhesive material in the manner
presently claimed, i.e., along the entirety of only some of the
corrugated crests and on at least one narrow edge zone of the
corrugated sheet. We find it significant, however, as pointed
out by the examiner and appreciated by appellant, that Nonnenmann
specifically teaches applying the brazing powder and adhesive
either across all of the corrugated crests or at the edges of the
crests in a discontinuous pattern. Consequently, based on the
collective teachings of Nonnenmann and the other references
applied by the examiner, we are convinced by the examiner's
reasoning that:
[T]o apply the coating completely along some of the
crests (such as the first and last crest of the
corrugated sheet in order to ensure a good bond between
the sheet and the flat web in the interior of the body
as well as to ensure that end edge of the wound body
was secured to the remainder of the body) while leaving
other crests coated along the edge (in order to reduce
the solder consumption as suggested by Nonnenmann et
al[.] or in order to render the finished body more
flexible and thus better able to handle thermal strain
as suggested by German Patent '944) would have been
obvious to one of ordinary skill in the art and a
prima facie case has been presented [page 11 of Answer,
lines 12 et seq., emphasis added].
We agree with the examiner that German '944 would have provided
ample motivation for one of ordinary skill in the art to apply
