Appeal No. 2006-1831 Application No. 09/755,383 As the pen-like tool interfaces with the direct drive manipulator, a control point stored in the manipulator senses the motion and position of the pen, as well as the degree of force that the pen is applying upon the surface of the manipulator to provide a haptic feedback the operator holding the pen. One of ordinary skill in the art would have duly recognized that Hannaford’s teaching of the control point is functionally equivalent to the claimed touchpad sensor, as they both serve the purpose of sensing the position, motion and the degree of force of an object (e.g. a pen or a mouse) as it moves across the surface of a direct drive manipulator or a touchpad. Thus, the ordinarily skilled artisan would have been motivated to use Hannaford’s disclosed control point in conjunction with Appellant’s mouse to provide a force feedback to the user while operating the mouse. Appellants also argue that Noll does not teach the touchpad sensor either, and thus, it does not cure the deficiencies of Hannaford. As noted in the discussion above, we find no such deficiencies in Hannaford for Noll to cure. In consequence, we do not find error in the Examiner’s position, stating that the 11Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
