          Hofvander claims are directed require that specifically                     
          identified antisense constructs be inserted into potato plant               
          cells to transform the potato cells and inhibit expression of               
          the potato gene therein and in potato plants cultivated                     
          therefrom.  The antisense constructs identified as being useful             
          for transforming potato plant cells and capable of suppressing              
          amylose formation in potato plants grown therefrom include DNA              
          sequences specifically identified in the respective claims.                 
               If the chemical structures of the DNA sequences in the                 
          antisense constructs Visser uses to genetically engineer potato             
          plants by established procedures to produce essentially amylose             
          free starch are the same, or substantially the same, as the                 
          chemical structures of the DNA sequences of the antisense                   
          constructs Hofvander describes for use in genetically engineering           
          its potato plants also by established procedures to suppress                
          amylose formation in potato tubers, absent any references to                
          patentably distinguishable genetic engineering methods in the               
          claims themselves, the different terminology the parties’                   
          respective claims employ to define function and/or specify                  
          utility does not make the same, or substantially the same,                  
          methods and constructs both parties appear to claim separately              
          patentable to each of them.  See In re Pearson, 494 F.2d 1399,

          forth the intended use for, or a property inherent in, an
