          Interference 103,579                                                        
          reasonably appear to be identical, or substantially identical,              
          and accordingly, the potato plants reasonably appear to be                  
          transformed by identical or substantially identical processes.              
          Compare In re Best, 562 F.2d 1252, 1255, 195 USPQ 430, 433 (CCPA            
          1977):                                                                      
                    Where . . . the claimed and prior art products are                
               identical or substantially identical, or are produced by               
               identical or substantially identical processes, the PTO                
               can require an applicant to prove that the prior art                   
               products do not necessarily or inherently possess the                  
               characteristics of his claimed product.                                
               In this case, the chemical structures of the DNA sequences             
          of the antisense constructs the parties’ claims describe are well           
          defined and readily compared.  Therefore, it unnecessary to                 
          determine the relative degrees of function indicated in the                 
          parties’ claims until we find, based on comparable structures               
          of DNA sequences, that the antisense constructs the parties                 
          respectively claim reasonably appear to be the same, or                     
          substantially the same, or conclude that the antisense constructs           
          of one party’s claims reasonably would appear to have been                  
          suggested by the other party’s claims.  See In re Mills, 916 F.2d           
          680, 683, 16 USPQ2d 1430, 1433 (Fed. Cir. 1990) (“It is not                 
          pertinent whether the prior art . . . possesses the functional              
          characteristics of the claimed invention if the reference does              
          not describe or suggest its structure”).                                    
                         (e)  “Sense” claims                                          

                                        -61-
