          Appeal No. 95-2784                                                          
          Application 08/193,634                                                      



          is established only when a single prior art reference                       
          discloses, expressly or under principles of inherency, each                 
          and every element of a claimed invention."  RCA Corp. v.                    
          Applied Digital Data Sys., Inc., 730 F.2d 1440, 1444, 221 USPQ              
          385, 388 (Fed. Cir.), cert. dismissed, 468 U.S. 1228 (1984),                
          citing Kalman v. Kimberly-Clark Corp., 713 F.2d 760, 772 218                
          USPQ 781, 789 (Fed. Cir. 1983), cert. denied, 465 U.S. 1026                 
          (1984).                                                                     
                    On pages 4-6 of the brief, Appellant argues that                  
          Hyatt fails to disclose the use of a single active processor                
          for controlling each of the functions recited in Appellant's                
          claim 1 and thereby does not anticipate Appellant's claims 1                
          through 3, 18 and 19.  In particular, Appellant points out                  
          that Hyatt teaches a data processor 12 that only performs a                 
          portion of the overall control of the movement along each of                
          the three axes.                                                             
          Appellant further points out that Hyatt teaches in Figure 3 an              
          additional processor which performs the function of receiving               
          feedback information and controlling the operation of one of                
          the motors.                                                                 

                                          5
