Appeal No. 2001-1787
Application 09/374,122
labyrinth” in claim 5 on appeal to be an end of the groove (15)
that extends to the periphery of the tool, as can clearly be seen
in Figures 2 and 3 of the application drawings. Since we find no
corresponding structure in Sprowls wherein a groove defining a
labyrinth extends to a periphery of the blocklike elements (10)
therein, we must for this additional reason refuse to sustain the
examiner’s rejection of appellant’s claim 5 under 35 U.S.C.
§ 102(b).
