Appeal No. 1996-4124
Application No. 08/307,088
using the grinding machine to manufacture sector-shaped parts
is a suggestion to use the grinding machine to grind tooth
flanks in toothed wheels. Thus, we find that Hahn is in the
same field of endeavor as claim 28.
Similarly, we find that Loehrke is in the same field of
endeavor as Appellant’s claim 28. We find that Loehrke
teaches a grinding machine with a grinding disc that cuts two
tooth flanks. See grinding disc item 16, of Loehrke’s figure
1 and the description on column 9, lines 45 to 55.
B) Limitation of continuous monitoring
On page 11 of the brief, Appellant asserts that Hahn does
not teach "continuous measuring of the grinding force as
recited in claim 28". Instead, Appellant asserts that Hahn
periodically monitors grinding force.
As we identified above, the scope of the "continuous
measuring of the grinding force" limitation of claim 28 is
that the grinding force is continuously sampled throughout the
grinding of the toothed wheel. Hahn teaches in column 14,
lines 17 through 20, that the grinding force is periodically
monitored. In column 13, lines 35 through 38, Hahn teaches
that the force is monitored throughout the grinding process.
