          Appeal No. 95-4433                                                          
          Application No. 07/994,040                                                  


          aforementioned characteristics of crystalline azithromycin                  
          dihydrate are significantly and unexpectedly superior to those              
          of crystalline azithromycin monohydrate.                                    
               Under the circumstances recounted above, it is our                     
          determination that the evidence of record, on balance, weighs               
          most heavily in favor of a nonobviousness conclusion.  It                   
          follows that we cannot sustain the examiner’s § 103 rejection               
          of claims 1 through 3 as being unpatentable over Bright in                  
          view of Desposato.                                                          





















                                          5
