Appeal No. 2001-0526 Page 7 Application No. 08/960,236 a X-Y location. We further find that the contact point configuration is identified because Verrier discloses that during initialization of the writing end of the stylus, the X-Y location and the Z separation values for the stylus for the writing end of the stylus 20 have their measured values depend on the particular stylus geometry and the overlay geometry of the tablet (col. 10, lines 22-31). Since the position detection is based in part upon the stylus geometry, the contact point configuration during a touch down of the stylus is inherently identified in order for the position signals to be radiated from the conductors of the tablet, which in turn are picked up by antenna 29. With respect to the limitation “identifying a user mode based on the identified contact point configuration" we note that the user modes disclosed by Verrier are “write" and “erase." In Verrier, the user modes are determined by the signals supplied to antenna 62 by the write and erase circuitry of the stylus. Because the shape of the contact portions 38, 38' for the write and erase contact portions of the stylus have the same configuration, the user input mode cannot be based upon the identified contact point configuration. We are not persuaded by the examiner's assertion (answer, page 4) that the limitation is met by Verrier's identifying thePage: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
