          Appeal No. 2000-1257                                                            
          Application 08/861,350                                                          

          claim must set out and circumscribe a particular area with a                    
          reasonable degree of precision and particularity when read in                   
          light of the disclosure and the teachings of the prior art as it                
          would be by the artisan.  Note In re Johnson, 558 F.2d 1008,                    
          1016, 194 USPQ 187, 194 (CCPA 1977); In re Moore, 439 F.2d 1232,                
          1235, 169 USPQ 236, 238 (CCPA 1971).                                            
               We have reviewed and considered the examiner’s reasons in                  
          support of the rejection, but are not convinced that the cited                  
          claims fail to comply with the second paragraph of 35 U.S.C.                    
          § 112.                                                                          
               The focus of the examiner's concern of each independent                    
          claim on appeal is the feature at the end of each independent                   
          claim that the value "r is the maximally permissible decrease of                
          the Strehl intensity due to spherical aberration."  At page 3                   
          of the answer, the examiner considers this terminology to be                    
          subjective rather than objective and the value of "r" is set                    
          forth in terms of a desired result.  Beginning at page 4 of the                 
          answer in the responsive arguments portion thereof, the examiner                
          variously considers the quoted material as not being clearly                    
          definable, that the value of "r" may range somewhat between less                
          than infinity down to zero indicating that the metes and bounds                 
          of the claimed invention would therefore not be clearly                         
          definable, and that the above-quoted claim limitation is based                  


                                            3
