          Appeal No. 95-2111                                                          
          Application 07/771,173                                                      

                    In regard to claim 10, the examiner contends that                 
          the term “its” in line 2 is indefinite as the antecedent                    
          thereof is unclear and “the full length” in line 6 lacks                    
          positive antecedent basis.  Appellants do not dispute the                   
          examiner’s position.  Rather, appellants contend on page 8 of               
          the amended brief that an amendment to the claims was filed                 
          and should have been entered and that had the amendment been                
          entered it would have overcome this rejection.  Since                       
          appellants have not pointed out how the examiner erred in this              
          rejection, and have in effect acquiesced therein, we are                    
          constrained to affirm the rejection under 35 U.S.C. § 112,                  
          second paragraph, of claim 10.                                              
                    We turn now to the rejection of claims 1-12 under 35              
          U.S.C. § 112, first paragraph.  In explaining this rejection                
          the examiner states:                                                        
                    Applicant’s disclosure has not taught one                         
                    of ordinary skill to form an “annular                             
                    pattern” and has not disclosed how to                             
                    prevent the intense coherent beam of light                        
                    from burning away the root canal in an                            
                    annular pattern [Examiner’s Answer at page                        
                    5].                                                               





                                         -7-
