          Appeal No. 95-1293                                                          
          Application 07/727,387                                                      


          the concentration of soluble fibrin in the body fluid".                     
          Where, as here, the examiner has not established that persons               
          having ordinary skill in the art would have expected that the               
          adsorption binding of Stemberger has the same strength and                  
          selectivity as the antigen/antibody binding of Scheefers-                   
          Borchel, we find that the references would not have led                     
          persons having ordinary skill in the art to appellants' method              
          for quantitatively determining soluble fibrin in a body fluid               
          with a reasonable expectation of success.                                   
               At most, a person having ordinary skill would have found               
          it obvious to try the proposed modification of the Scheefers-               
          Borchel, per the teachings of Stemberger and "if necessary",                
          Tom.                                                                        


          Obvious to try, however, is an improper consideration in                    
          adjudicating obviousness.  Hybritech Inc. v. Monoclonal                     
          Antibodies, Inc.  802 F.2d 1367, 1380, 231 USPQ 81, 91 (Fed.                
          Cir. 1986).                                                                 
               The examiner's decision is reversed.                                   
                                      Reversed                                        


                                          6
