         Appeal No. 2001-2065                                                       
         Application 09/124,871                                                     

                                      OPINION                                       
              Allen discloses the subject matter of claim 1 except for              
         the large signal receiving element of the second large target              
         area "including a signal sensing portion which is electrically             
         distinct from the signal receiving element of said first                   
         target area and also electrically distinct from the remainder              
         of the total area of the signal receiving element of said                  
         second target area" and the added signal sensing portion being             
         electrically connected to the processing means.                            
              Allen does not recognize the problem of inaccuracy in                 
         missile location detection where a large area signal receiving             
         element, such as element E  corresponding to target area A ,1                           1                   
         adjoins a smaller area signal receiving element, such as                   
         element E  corresponding to target area A .  Nor does Allen2                            2                                   
         suggest Appellant's solution of dividing the large area signal             
         receiving element into two portions including a signal sensing             
         portion of an area substantially equal to the first target                 
         area and located adjacent to the first target area.  However,              
         it is noted that claim 1 recites dividing the larger signal                
         receiving element into two smaller electrically distinct                   
         portions, but does not recite that the smaller signal sensing
