PATENT INTERFERENCES NO. 102,922 & 103,088 DUMAS V. GILL - Page 26




          Interference No. 102,922                                                    
          Interference No. 103,088                                                    
          dicyandiamide and diethylenetriamine (U.S. Patent 4,426,466,                
          Table II, column 4, lines 8-24, column 10, lines 15-25) and                 
          that the AKD resins are, in fact, cationic and possess                      
          tertiary and quaternary amine groups (U.S. Patent 4,405,408,                
          column 1, lines 60-61, column 4, lines 47-62).                              
               Moreover, as pointed out by Dumas, Gill employs HerconŽ                
          emulsions himself in his application.  Gill argues that since               
          he                                                                          
          did not identify which HerconŽ emulsion he used, it is not                  
          enough                                                                      





          to identify the alkyl ketene dimer and cationic properties.                 
          We find Gill's argument without merit.  Certainly the reliance              
          on the commercially available HerconŽ emulsions to identify                 
          the alkyl ketene dimer and its cationic properties of the                   
          count by Gill must also be accepted as sufficient for Dumas.                
               Gill also argues that Dumas did not establish whether or               
          not the HerconŽ used in DX 7 and 9 had the required "R" value               
          with 8 or more carbon atoms.  Gill alleges that the R may be                
          one                                                                         
                                         26
