KATOU et al. V. BELKO - Page 5




          been designated as corresponding to Count 1.  The reason the                
          prior art reference anticipates Katou claims 11-16, 20 and 25-              
          28 is because it describes a compound having the formula of                 
          Katou claim 11 and Katou claim 19 wherein n is 10.  The                     
          reference does not purport to describe any compound having a                
          value other than n is 10.                                                   
               The parties have agreed that a judgment should be entered              
          against both parties.  Counsel for Katou agreed that a                      
          judgment has to be entered with prejudice as to all claims                  
          (because those claims cover compounds wherein n is 10).                     
          Counsel for Katou believes, however, that a plausible argument              
          can be made that compounds wherein n is 9 or less and                       
          compounds wherein n is 11 or more are patentably distinct from              
          compounds wherein n is 10.  On that basis, counsel for Katou                
          requested entry of a judgment with prejudice as to compounds                
          wherein n is 10, but without prejudice to compounds wherein n               
          is 9 or less or n is 11 or more.  In light of the fact that                 
          Belko and the prior art reference describe only a compound                  
          wherein n is 10 and the utility of the Belko compound and the               
          Katou compounds are entirely different, an opportunity should               
          be provided to Katou to establish before the primary examiner               
          the separate patentability of compounds wherein n is 9 or less              
          and compounds wherein n is 11 or more.  Counsel for Belko has               

                                        - 5 -
