          Appeal No. 2002-1971                                                         
          Application 09/020,668                                                       

          referring to column 4, lines 6-53, and Figs. 1 and 3 (R3; EA4).              
          The examiner finds that the steps of applying first and second               
          filter criteria as recited in paragraphs (c) and (d), and the                
          steps of displaying of paragraphs (e) and (f), are met by the                
          "find tool" which displays previously read e-mail messages in the            
          background, which the examiner considers a first lens, and unread            
          e-mail messages in the foreground, which the examiner considers a            
          second lens (R3-4; EA4).                                                     
               Initially, appellant argues that it is unclear from the                 
          examiner's rejection what elements correspond to the "information            
          elements" and what correspond to the "lenses" (Br10).  Appellant             
          argues that if the examiner's position is that the documents in              
          Lucas correspond to information elements, and that the find                  
          function that separates a strand into sub-strands is the filter              
          function, Fig. 9 of Lucas does not disclose first and second                 
          lenses, where first and second filter criteria are applied to the            
          information elements for displaying different filtered sets of               
          information in each of those lenses (Br10).  It is argued that it            
          appears that all of the documents, including those in each                   
          sub-strand defined by a find tool are displayed in the same                  
          window or lens (Br10).                                                       
               The examiner responds that "lenses" or windows in Lucas                 
          contain "information elements" or data (EA11).  The examiner                 
          refers to documents 100a to 100e in Fig. 9 as "windows" (EA11).              

                                        - 5 -
