          Appeal No. 1998-0828                                                        
          Application 08/438,091                                                      

          guide arm 21 or load arms 22 and 22'.  The claimed invention                
          permits the microcontroller to control movement of the air                  
          bearing right at the location of the air bearing.  The                      
          “microcontroller” of Mori can not accomplish this operation.                
          Since there is at least one feature of the claimed invention                
          which is not disclosed in Mori, we do not sustain this rejection            
          of claims 19, 21, 22 and 24.                                                
          We now consider the various rejections under 35 U.S.C.                      
          § 103.  In rejecting claims under 35 U.S.C. § 103, it is                    
          incumbent upon the examiner to establish a factual basis to                 
          support the legal conclusion of obviousness.  See In re Fine, 837           
          F.2d 1071, 1073, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988).  In so               
          doing, the examiner is expected to make the factual                         
          determinations set forth in Graham v. John Deere Co., 383 U.S. 1,           
          17, 148 USPQ 459, 467 (1966), and to provide a reason why one               
          having ordinary skill in the pertinent art would have been led to           
          modify the prior art or to combine prior art references to arrive           
          at the claimed invention.  Such reason must stem from some                  
          teaching, suggestion or implication in the prior art as a whole             
          or knowledge generally available to one having ordinary skill in            
          the art.  Uniroyal, Inc. v. Rudkin-Wiley Corp., 837 F.2d 1044,              
          1051, 5 USPQ2d 1434, 1438 (Fed. Cir.), cert. denied, 488 U.S. 825           
                                         -8-
