          Appeal No. 96-3949                                                          
          Application No. 08/230,383                                                  


          The various passages in Okude referenced by the Examiner                    
          (Answer, page 3) describe an iterative procedure in which                   
          elements are altered from an initial placement until                        
          optimization is achieved.  The Examiner contends (Answer,                   
          pages 8 and 9) that cell interchange transpositions in Okude                
          would inherently be stored in a list to facilitate the                      
          handling of the numerous placement interchanges.                            
               In response, Appellants argue at pages 8 and 9 of the                  
          Answer that Okude utilizes a conventional cell placement                    
          representation which consists of a table of cells and their                 
          locations. Appellants contrast this with their claimed storing              
          and representation of cell placement as an initial cell                     
          placement in combination with a set of cell transpositions                  
          from which the cell placement can be derived.  As to the                    
          Examiner's argument regarding the inherency of storing cell                 
          transpositions in                                                           
          Okude, Appellants initially contend (Brief, page 9) that the                
          Examiner is not relying on a single prior art reference as                  
          required by the principles of anticipation.  Appellants                     
          apparently base this argument on their view that the Examiner               
          is, in effect, combining the prior art with an unsupported                  
                                          5
