          Appeal No. 1998-2823                                                        
          Application No. 08/458,010                                                  




                              NEW GROUND OF REJECTION                                 
               In accordance with our authority under 37 CFR § 1.196(b),              
          this panel of the board introduces the following new ground of              
          rejection.                                                                  
               Claim 27 is rejected under 35 U.S.C. 112, second                       
          paragraph, as being indefinite for failing to particularly                  
          point out and distinctly claim the subject matter which                     
          applicants regard as the invention.                                         


               Claim 27 recites the limitation “said second optical                   
          opening” in line 5 (as reproduced in “Exhibit A”).  There is                
          insufficient antecedent basis for this limitation in the                    
          claim.                                                                      


                                       REMAND                                         
               The scope of enablement required by 35 U.S.C. § 112,                   
          first paragraph, must bear a “reasonable correlation” to the                
          scope of the claims (see, e.g., In re Fisher, 427 F.2d 833,                 
          839, 166 USPQ 18, 24 (CCPA 1970)) and “the specification must               
          teach those skilled in the art how to make and use the full                 
                                         11
