          Interference No. 102,712                                                    

          34-38, 98).  On the other hand, Augustine’s specification (p.               
          10, l. 11-16) indicates that the “most preferred” whisker                   
          content is about 20%.  This noncorrespondence is consistent                 
          with the view that Augustine did not consider the WG-300                    
          embodiment of his invention to be better than any other, at                 
          least in terms of whisker content.                                          
               Finally, in reviewing the numerous court decisions cited               
          by Suzuki and Augustine relating to the “best mode” issue, we               
          find that our view of the facts and our legal conclusions are               
          consistent with case law for the reasons noted by Augustine                 
          (AB 46-8; ARB 70-88).  Since the case law has been thoroughly               
          addressed by Augustine, we find it unnecessary to do so here                
          on a case-by-case basis.  Suffice it to say that our                        
          evaluation of the evidence before us is consistent with the                 
          two-step analysis set out in Chemcast Corp. v. Arco Industries              
          Corp., 913 F.2d 923, 927-28, 16 USPQ2d 1033, 1036-37 (Fed.                  
          Cir. 1990).  Essentially, our evaluation of the evidence as a               
          whole led us to conclude that Suzuki has failed to establish                
          that the best or preferred mode contemplated by Augustine of                
          carrying out his invention is limited solely to the WG-300                  
          embodiment.  From the evidence, it does not appear that                     
          Augustine considered the WG-300 embodiment “to be better than               
                                         23
