looking at Figure 2 that bearing 15 is a hydrostatic bearing.
The examiner responds:
Appellant would have the Board
believe that the spaces around
elements 15, 16, 17 in his figure
2 are indicative of ports and
grooves for a hydrostatic
bearing. The examiner is of the
opinion that the spaces in figure
2 are similar to the spaces
around elements 10, 12, 13, 14 in
appellant’s figure 1 which merely
represent spaces between parts.
Even if one concluded that the
spaces in figure 2 were ports and
grooves, they would further
conclude that these ports and
grooves were lubrication
structures for grease and not for
hydrostatic bearings since no
additional structure is present
to provide fluid for a
hydrostatic arrangement, i.e., no
sump, pump or connecting lines
are present. [Examiner Answer at

We agree with the analysis of the examiner. Appellant
argues that those of ordinary skill in the art would know by
looking at Figure 2, that bearing 15 is a hydrostatic bearing.
Filed along with the reply brief, is a document of unknown
origin, entitled “Outline of Mechanical Structure” which
depicts hydrostatic pressure pockets on a worktable. We
initially note that the exhibit was not accompanied by a
