Appeal No. 2002-0441 Page 5
Application No. 09/273,152
(PPG-5-ceteh-20) at column 6, line 42 of Greczyn. The surfactant in that case,
however, is used as a coupling agent, and the rejection provides no motivation
for including a coupling agent or that particular coupling agent in the cosmetic
composition of Lee. The examiner also points to the teaching of polysorbate-20
and PEG distearate at column 7, lines 2-5 of Greczyn. Greczyn teaches the use
of a large number of different nonionic surfactants, and there is no teaching or
suggestion that would allow one of ordinary skill in the art to differentiate
between those surfactants that would fall within the invention and those that
would not. In addition, the PEG-distearate preferred by Greczyn is PEG-12
distearate, while claim 24 lists PEG-8 distearate, and the rejection does not
address whether the PEG-12 distearate preferred by Greczyn has the properties
required by the claimed invention.
