Appeal No. 2006-0962 8
Application No. 10/117,981
suggestion for one of ordinary skill in the art to attempt to
substitute the specially configured guiding grooves in Arbeus for
the cutting/shredding grooves (50) present in Hartman.
Moreover, given the apparent importance of the single spiral
blade in the pump arrangement of Hartman (see, e.g., col. 1,
lines 1-9), we do not see that it would have been obvious to one
of ordinary skill in the art to replace the single spiral blade
(42) with plural vanes as disclosed in the clearly different pump
arrangement of Arbeus.
In light of the foregoing, the rejection of independent claim
15, and of claims 16 through 23 which depend therefrom, under
35 U.S.C. § 103(a) will not be sustained. Thus, the decision of
the examiner is reversed
