powders and particulate materials. From our perspective, the2
Keem disclosure contains no suggestion for coating such
materials.
Keem discloses a process for coating surfaces or
substrates which are specifically disclosed to be in the form
of valve
piston rings (see example 1 in column 11), a flat plate (see
example 2 in column 11) and the cutting edge of a tool (see
claims 43 and 44 in column 14). As alluded to by the examiner
in the above quotation, patentee teaches that the low
temperature sputtering operation of his process is
particularly useful for coating certain materials including
graphite, plastics, and other substrate materials which are
adversely affected by elevated temperature (see lines 43-52 in
column 10). However, we perceive nothing and the examiner
Based on the record before us, it is also clear that the examiner does2
not rely upon any of the secondary references for a suggestion of using Keem’s
process for coating the here claimed materials. Instead, these secondary
reference are relied upon by the examiner for a suggestion of providing Keem’s
process with an agitation step (which relates to a feature recited only in
certain dependent claims on appeal); e.g., see the last paragraph on page 13
of the answer.
