50 to column 17, line 51). Moreover, Palazzotto does not
teach any particular utility for polymerizable vinyl ethers
but rather generally indicates that the large variety of
polymerizable compositions discussed therein may possess
particular specified utilities among those disclosed
"...depending on the particular cationically-sensitive monomer
and ionic organometallic complex used" (column 18, lines 14-
26). Hence, in our view, the examiner has not established why
the combined references teachings would have led one skilled
in the art to modify Tumey so as to arrive
at the claimed invention with a reasonable expectation of
success as argued by the examiner. Accordingly, we will not
sustain the stated rejection.
Rejection over Tumey taken with Rinker
From our perspective, the examiner's second stated
rejection also falls short of establishing the prima facie
obviousness of the claimed abrasive article since Rinker, like
Palazzotto above, does not remedy the deficiencies of Tumey.
Rinker teaches that a resin composition including a
formaldehyde containing thermosetting resin and a compatible
elastomeric or thermoplastic resin may be used as part of a
