                 Appeal No. 2002-2169                                                                                  Page 6                     
                 Application No. 09/163,286                                                                                                       


                 claim the subject matter which applicant regards as the invention."  37 C.F.R.                                                   
                 § 1.192(c)(8)(ii) (2002).                                                                                                        


                         Here, the appellants' argument is not responsive to the examiner's rejection.                                            
                 More specifically, although the examiner asserts that the meaning of the claim's                                                 
                 "frequency offset" is unclear, the appellants argue that the claim specifies how the                                             
                 offset is determined and how it is used.  The argument does not allege, let alone show,                                          
                 that the meaning of "frequency offset" is clear.                                                                                 


                         Third, the examiner asserts that in claim 12, "[i]t is unclear to what the language                                      
                 'provide a calibration signal' refers.  Is the calibration signal related to the frequency                                       
                 offset?"  (Examiner's Answer at 4.)  The appellants argue, "[a] free running local                                               
                 oscillator can either be phase locked to a sub-harmonic of the atomic clock based                                                
                 satellite carrier transmissions, or those transmissions can be used to measure the local                                         
                 clock errors."  (Reply Br. at 3.)                                                                                                


                         Again, the appellants' argument is not responsive to the examiner's rejection.                                           
                 More specifically, although the examiner asserts that the claimed providing of a                                                 
                 calibration signal is unclear, the appellants argue that a local oscillator can either be                                        
                 phase locked to a sub-harmonic of an atomic clock based satellite carrier
