             Appeal No. 96-1231                                                                                   
             Application 08/165,143                                                                               


             08/177,837.  Because Application 08/177,837 has issued as a                                          
             patent, i.e., Cava ‘530, we treat this rejection as an                                               
             obviousness-type double patenting                                                                    




             rejection over claims 1-5 of that patent.  Appellants’ claims                                        
             1 and 3-6 also stand rejected under the judicially created                                           
             doctrine of obviousness-type double patenting over claim 1 of                                        
             Cava ‘755.                                                                                           
                                                    OPINION                                                       
                    Appellants do not contest the obviousness-type double                                         
             patenting rejection of claims 1, 3 and 4 over claims 1-5 of                                          
             Cava ‘530.  We therefore summarily affirm this rejection.                                            
                    As for the obviousness-type double patenting rejection of                                     
             claims 1 and 3-6 over claim 1 of Cava ‘755, we have carefully                                        
             considered all of the arguments advanced by appellants and the                                       
             examiner and agree with appellants that this rejection is not                                        
             well founded.  Accordingly, we do not sustain this rejection.                                        
             The superconducting material recited in appellants’                                                  
             claims has a general formula which requires 1 to 4 atomic                                            
             units of boron and an atomic ratio of carbon to boron in the                                         
                                                       -3-3
