          Appeal No. 1998-1668                                                        
          Application No. 08/469,670                                                  


               (b)  reacting said precursor in said fluid bed in the                  
          presence of finely divided particles of a catalyst for                      
          converting said precursor to fibrils without the coproduction               
          of a thermal carbon overcoat under fibril-forming reaction-                 
          conditions; and                                                             
               (c)  removing fibrils from said reactor at an effluent                 
          port located in a lower part of said vertical reactor.                      
               In the rejection of the appealed claims, the examiner                  
          relies upon the following patent to appellants:                             
          Mandeville et al.             5,500,200             Mar. 19, 1996           
          (U.S. '200)                                                                 
               Appellants' claimed invention is directed to a method and              
          apparatus for producing carbon fibrils without the                          
          coproduction of a thermal carbon overcoat.  The method                      
          comprises introducing a gaseous fibril precursor into the                   
          lower part of a vertical fluid bed reactor, reacting the                    
          precursor in the presence of a catalyst, and removing the                   
          produced fibrils from the reactor through a port located in                 
          the lower part of the vertical reactor.                                     
               Appellants submit at page 4 of the Brief that "[t]he                   
          presently pending claims are believed to stand or fall                      
          together with respect to the presently pending rejection."                  
          Accordingly, all the appealed claims stand or fall together                 
          with claim 26.                                                              

                                         -2-
