Appeal No. 1996-2703
Application 08/339,637
adhesive, selectively remove adhesive from undesired
areas, heat the adhesive to a fused, adhering state, and
ship the resulting product to the ultimate fabricator
such as the airplane manufacturer. Thus, the adhesive of
this invention provides the opportunity for a form of
marketing of structural units hitherto impossible with
previous structural adhesives, giving the ultimate
manufacturer the option of concentrating on the final
assembling techniques to which it is best suited.
The examiner has not explained why one of ordinary skill
in the art would have reasonably expected the thermoplastic
adhesives of Fell and Lynam to provide the above properties
and processing benefits of McKown’s adhesive, or why the
applied references would have led such a person to modify
McKown’s process such that these benefits are given up to
obtain a shorter cycle time. The examiner, therefore, has not
carried the burden of establishing a prima facie case of
obviousness of the invention recited in any of appellants’
claims.
