not move in response to further movement of the mouse.
Appellants appear to agree with the examiner that Barker
discloses a “first operational mode” similar to appellants in
that movement of the mouse effects commensurate movement of the
cursor on the screen and that this movement corresponds to
operation of the mouse when the system is not in scroll mode.
However, it is appellants’ position that the claimed “second
mode” corresponds to the scroll mode and the claim requires that
“when the cursor is on the frame icon 41 (the second indicium) in
the scroll mode, any sensed movement of the mouse in either of
two opposite directions will not affect the location on the
screen of the cursor and will not affect the location of [sic,
on?] the screen of the icon” [Principal brief-page 13].
Appellants further state that the claim recitation of “responsive
to any movement of the mouse detected by the X-Y motion sensor”
“requires the scrolling function to occur in response to a sensed
mouse movement in the first of the two opposite directions and in
response to a sensed mouse movement in the second of the two
opposite directions” [Principal brief-page 13].
Both appellants and the examiner are in agreement as to how
the Barker device functions. Clearly, when setting the line size
function, Barker’s pointer moves on the screen in correspondence
