          Appeal No. 2004-1062                                                        
          Application No. 08/448,019                                                  

          esters of Zwiener.  As properly noted by the examiner, it is a              
          matter of obviousness for one of ordinary skill in the art to               
          combine the components taught by the prior art to be useful for             
          the same purpose.  In re Kerkhoven, 626 F.2d 846, 850, 205 USPQ             
          1069, 1072 (CCPA 1980).                                                     
               The examiner also appreciates that neither Aoki nor Zwiener            
          teaches the specific claimed isocyanate functional urethane.                
          However, appellant does not take issue with the examiner’s legal            
          conclusion that it would have been obvious for one of ordinary              
          skill in the art to employ the specific isocyanate functional               
          urethane of Druetzler in the coatings of Aoki and Zwiener for the           
          purpose of obtaining flexible coatings (see page 7 of answer).              
               Appellant contends that “the Examiner has ignored the fact             
          that Aoki discloses a moisture curable coating composition in               
          which there is an excess of free isocyanate groups to react with            
          atmospheric moisture after the coating composition is applied to            
          the object to be coated” (page 5 of principal brief, first                  
          paragraph).  However, we, like the examiner, do not understand              
          the relevancy of this argument inasmuch as appellant has failed             
          to explain how Aoki’s teaching of a moisture curable compo-
