          Appeal No. 97-0673                                                          
          Application 08/143,370                                                      

          The appellants argue that the position of the examiner is mere              
          "wishful reading" and that there is nothing in Kolomiets to                 
          support the examiner’s position.                                            
               The examiner’s view with respect to Kolomiets’ lens 5 and              
          mirror 6 is misplaced.  They evidently do not provide a return              
          beam which precisely retraces the path of the incident beam.                
          In Kolomiets, it is stated on page 2, lines 18-22, that the                 
          reflected beam is shifted in the direction of the particle’s                
          movement by a certain magnitude.  On page 4, lines 1-2,                     
          Kolomiets further states that the incident beam a and the                   
          return beam b are spread by a magnitude equal to 2F.  We agree              
          with the appellants that the examiner has not a sufficient                  
          basis to shift the burden of proof to the appellants with                   
          regard to whether the lens 5 and mirror 6 together constitute               
          an optical phase conjugator.                                                
               Accordingly, the rejection of claim 11, and claims which               
          depend either directly or indirectly from claim 11, i.e.,                   
          claims 14-16 and 26-32, will not be sustained.                              
                                     Conclusion                                       





                                          13
