appellant that Hong's single reference to a boron nitride
particle size of about 1 micron (column 2, lines 9-11) clearly
does not teach or suggest appellant's claimed bimodal size
distribution that requires boron nitride particles of two
distinct size ranges; but, rather suggests a substantially
singular or uniform particle size of about 1 micron (Brief,
page 6).
Since the examiner acknowledges that Christian does not
even teach the use of boron nitride as a grease component
(Answer, page 5), the addition of the latter reference to the
teachings of Hong does not cure the above-noted deficiency.

11 likewise falls short of presenting a prima facie case of
