                 Appeal 2007-0909                                                                                      
                 Application 10/881,407                                                                                

                        Accordingly, on this record, the scope of claims 10 through 15 is so                           
                 indefinite under § 112, second paragraph, as to require speculation as to the                         
                 metes and bounds of the claimed subject matter, and thus, because the claims                          
                 cannot be analyzed to determine whether they are patentable over Keefer,                              
                 the ground of rejection over this reference cannot be supported.  See, e.g., In                       
                 re Steele, 305 F.2d 859, 862-63, 134 USPQ 292, 295 (CCPA 1962)                                        
                 (rejection over prior art cannot be based on speculation and assumptions as                           
                 to the scope of the claims).                                                                          
                        Therefore, on this record, we reverse the ground of rejection of claims                        
                 10 through 15 under 35 U.S.C. § 102(e) over Keefer pro forma.                                         
                        The Primary Examiner’s decision is reversed.

                        We decline to exercise our authority under 37 C.F.R. § 41.50(b)                                
                 (2006) and enter a new ground of rejection of claims 10 through 15, under                             
                 35 U.S.C. § 112, second paragraph, leaving this matter to the Examiner to                             
                 consider upon any further prosecution of the appealed claims subsequent to                            
                 the disposition of this appeal.
