         Appeal No. 2001-0131                                                       
         Application No. 08/977,110                                                 

         elements of the prior art.”); In re Rouffet, 149 F.3d 1350,                
         1359, 47 USPQ2d 1453, 1459 (Fed. Cir. 1998) (“[T]he Board must             
         explain the reasons one of ordinary skill in the art would have            
         been motivated to select the references and to combine them to             
         render the claimed invention obvious.”); In re Dembiczak, 175              
         F.3d 994, 999, 50 USPQ2d 1614, 1617 (Fed. Cir. 1999) (“[T]he               
         best defense against the subtle but powerful attraction of a               
         hindsight-based obviousness analysis is rigorous application of            
         the requirement for a showing of the teaching or motivation to             
         combine prior art references.”).                                           
              None of the other applied prior art references remedy the             
         fundamental deficiency in the examiner’s analysis.                         
              For these reasons, we hold that the examiner has not                  
         established a prima facie case of obviousness.  We therefore               
         reverse the examiner’s rejection under 35 U.S.C. § 103(a) of all           
         the appealed claims as unpatentable over Ueki or Mehra in view             
         of Burns, Christiansen, Dexter, Boni, Itamura, Henman, Herman,             
         and Dobreski.
