          Application No. 08/569,529                                                  


          of persons skilled in the art to complement that [which is]                 
          disclosed ....’”  In re Bode, 550 F.2d 656, 660, 193 USPQ 12,               
          16 (CCPA 1977) (quoting In re Wiggins, 488 F.2d 538, 543, 179               
          USPQ 421, 424 (CCPA 1973)).  Those persons “must be presumed                
          to know something” about the art “apart from what the                       
          references disclose.”  In re Jacoby, 309 F.2d 513, 516, 135                 
          USPQ 317, 319 (CCPA 1962).  We next address the obviousness of              
          the following groups of claims:                                             
               •    claims 1 and 5-7                                                  
               •    claims 2-4                                                        
               •    claims 15-18.                                                     


                                  Claims 1 and 5-7                                    
               The appellants make three arguments.  First, the                       
          appellants argue, “The Examiner asserts that claim 1 of the                 
          present invention would have been obvious in view of Sato,                  
          Dirks and Layton et al. but this is Monday morning                          
          quarterbacking.”  (Appeal Br. at 5.)                                        


               The appellants misconstrue the criteria for combining                  
          references.  “‘[T]he question is whether there is something in              
          the prior art as a whole to suggest the desirability, and thus
