Appeal No. 2001-2065
Application 09/124,871
The Examiner states that Vranish, Schulz, and Santos
teach that sensors can be added to enhance the measurement
resolution and that "the designer of the dart board could
selectively place additional sensors of Allen's system for
increased resolution" (EA8). The Examiner states that it is
difficult to conceive of a more obvious method of improving
resolution than by providing extra sensors and that
duplication of sensors for improved effect is hornbook
engineering (EA8).
Appellant argues that Allen does not suggest that the
signal pickup elements are broken into portions or multiplied
(RBr4). It is argued that the present invention is more than
mere multiplication of sensor elements (RBr6-7).
Again, we find no reason why one of ordinary skill in the
art would have been motivated to increase the resolution
within a target area in Allen. It is not necessary to
discriminate between different areas of the same target area
because all points within a target area have the same value.
Allen does not disclose or suggest that there is a problem
with using a single signal receiving element for each target
area. It is immaterial that a designer of the dart board
