          Application No. 08/241,888                                                  


          support of their respective positions.  As a consequence of                 
          this review, we make the determinations which follow.                       
               As evidence of obviousness of the claimed subject matter               
          under 35 U.S.C. § 103, the examiner relies on the combined                  
          teachings of Touval, Breitenfellner and Sandler.  The examiner              
          relies on Touval to demonstrate that dehydrating a mixture of               
          a hydrated sodium antimonate and a certain polymer during the               
          production of a flame proofing or fire retardant would have                 
          been obvious to one of ordinary skill in the art.  See Answer,              
          page 5-8.  The examiner then relies on Breitenfellner and                   
          Sandler to establish that the use of the claimed specific                   
          polymers and other ingredients in the process of Touval would               
          have been obvious to one of ordinary skill in the art.  See                 
          Answer, pages 6-8.  However, as indicated by appellants at                  
          page 4 of the Reply Brief, Touval does not teach dehydrating a              
          mixture of a hydrated sodium antimonate and at least one                    
          polymer.  Touval teaches drying the hydrated sodium antimonate              
          prior to incorporating it to a polymer formulation for the                  
          production of a flame proofing or fire retardant in an                      
          extruder.  See, e.g., column 6, line 3, column 7, lines 50-53.              
          Although the examiner appears to argue that Touval inherently
