          Appeal No. 1997-2446                                                         
          Application 08/223,351                                                       



          functionality to the polymer and can introduce salts into the                
          product.  Again, see Holy at column 2, lines 8 through 12.                   
                    Appellants contend that even if a prima facie case of              
          obviousness has been established from the combined teachings of Holy,        
          Hughes and SE, evidence of unexpected results found in TABLE 2 and           
          TABLE 1 of the specification at pages 31 and 27, respectively, are           
          adequate to rebut the prima facie case of obviousness.  Initially,           
          and contrary to appellants' arguments, in submitting evidence to             
          establish unobvious results, it is appellants that have the burden of        
          indicating how the examples asserted to represent the claimed process        
          are considered to relate to the examples intended to represent prior         
          art, and particularly to indicate how the prior art examples                 
          represent  the closest prior art.  Moreover, such evidence relied            
          upon must                                                                    


          also be reasonably commensurate in scope to the subject matter               
          claimed.  Further, such evidence should establish that the                   
          differences in results obtained are in fact unexpected to a person of        
          ordinary skill in the art and are of practical                               
          significance.  See Ex parte Gelles, 22 USPQ2d 1318, 1319 (Bd.
