         Appeal No. 2006-2106                                                       
         Application No. 09/837,632                                                 
         led to modify the prior art or to combine prior art references to arrive at the claimed
         invention.  See also In re Rouffet, 149 F.3d 1350, 1355, 47 USPQ2d 1453, 1456 (Fed.
         Cir. 1998).  Such evidence is required in order to establish a prima facie case.  In re
         Piasecki, 745 F.2d 1468, 1471-72, 223 USPQ 785, 787-88 (Fed. Cir. 1984); In re Cofer,
         354 F.2d 664, 668, 148 USPQ 268, 271-72 (CCPA 1966).  However, the         
         motivation, suggestion or teaching may come explicitly from                
         statements in the prior art, the knowledge of one of ordinary              
         skill in the art, or, in some cases the nature of the problem to           
         be solved.  See In re Dembiczak, 175 F.3d 994, 999, 50 USPQ2d              
         1614, 1617 (Fed. Cir. 1999).                                               
              A review of Miksovsky confirms that the reference relates to          
         a dynamic error messaging system (abstract) wherein updated error          
         messages corresponding to a predetermined or numbered error is             
         outputted (col. 5, lines 56-67).  According to Miksovsky, an               
         updated error message for that error is searched (col. 6, lines            
         6-11) and formatted prior to displaying to the user (col. 6,               
         lines 64-67).
