In proposing to combine Yamaguchi and Cribari in

concludes that it would have been obvious at the time the
invention was made to a person having ordinary skill in
the art "to employ in Yamaguchi deformations in the
tubular wall in two symmetrically disposed, localized
regions for the purpose of ease of assembly as recognized
by Cribari" (answer, page 4).
As indicated above, independent claim 10 recites a
method for producing a heat exchanger comprising, inter
alia, the step of forming the openings in the fluid box
compartment for the heat exchanger tubes "before" the
transverse partitions are positioned and immobilized by
deformation. The examiner has found that Yamaguchi
discloses a method of manufacturing a heat exchanger
comprising the step of "inserting partitions 71, 72 into
tubular wall 130 having tube receiving openings therein"
