Appeal No. 96-2504
Application 08/318,328
the extent that their incorporation in the claimed composition
would materially affect the basic and novel characteristic of
the claimed invention.
As for the separately argued claims, we are satisfied
that Hombach's disclosure of preparing polyisocyanates from a
polyether polyol having about 10 ethylene oxide units
establishes a prima facie case of obviousness for the claimed
polyether polyol having 9 ethylene oxide units. Also, we are
convinced that one of ordinary skill in the art would have
found it obvious to include a pigment, as well as a filler, in
adhesive compositions of Hombach for the purpose of adding
color to the composition. Also, concerning the section 103
rejection of the appealed claims, we note that appellants base
no argument upon objective evidence of nonobviousness, such as
unexpected results.
In conclusion, based on the foregoing, the examiner's
decision rejecting the appealed claims is affirmed.
No time period for taking any subsequent action in
