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

               We agree with appellant that the rejection (Paper No. 28)               
          does not clearly specify how the claimed "lenses" and                        
          "information elements" correspond to elements in Lucas.  It was              
          therefore reasonable for appellant to guess that the examiner                
          interpreted the "information elements" to correspond to the                  
          document representations (e.g., 19a to 19e in Fig. 1 or 100a to              
          100e in Fig. 9) and the "lens" to correspond to the window in                
          which the documents are displayed (e.g., the window in Figs. 1 &             
          2).  Documents 100a to 100e in Fig. 9 are screen objects which               
          are visual representations of documents and are not "windows," as            
          stated by the examiner, in the usual sense of scrollable viewing             
          areas on the screen.  The specification states that "[l]enses are            
          much like windows in common GUI environments, insofar as they                
          provide a window into a portion of the information in a body of              
          knowledge" (specification, p. 29).  Nevertheless, we will use the            
          examiner's interpretation of document objects 100a to 100e in                
          Fig. 9 as "lenses" showing "information elements."  These                    
          "lenses" are oriented perpendicular to a strand path, which the              
          examiner considers to be the "abstraction axis."  Thus, according            
          to the examiner's interpretation, Fig. 9 shows five lenses (100a             
          to 100e), one for each information element.                                  
               Appellant argues that if the examiner takes the alternate               
          position that the documents in Lucas correspond to lenses, the               
          find function does not affect what is displayed within each                  

                                        - 6 -
