          Appeal No. 1998-0823                                                        
          Application 08/630,542                                                      


          suggest selectively deflecting the available light to only one              
          of two camera ports. On pages 22 to 25 of the Brief,                        
          Appellants argue that the asserted combination of Heimstadt,                
          Muller, Braymer, and either Minami or Kleinberg fails to teach              
          the invention of claims 30 and 35 essentially because Muller,               
          Minami and Kleinberg are directed to low power surgical                     
          microscopes, and Braymer is directed to a telescope, such                   
          devices asserted to be unrelated to Appellants’ invention,                  
          characterized as a "high power microscope."                                 
               The Federal Circuit states that "[t]he mere fact that the              
          prior art may be modified in the manner suggested by the                    
          Examiner does not make the modification obvious unless the                  
          prior art suggested the desirability of the modification."

          the inventor."  Para-Ordnance, 73 F.3d at 1087, 37 USPQ2d at
