                   establishing a prima facie case.  To the extent that the examiner                                                                                      
                   may be relying on inherency to establish anticipation, we note                                                                                         
                   that it is well settled that inherency may not be established by

                   666 F.2d 578, 581-82, 212 USPQ 323, 326 (CCPA 1981).  In the                                                                                           
                   present case, the disclosure of Denninger does not appear to                                                                                           
                   provide an adequate factual basis to clearly establish that the                                                                                        
                   natural result flowing from following the teachings of that                                                                                            
                   reference would be a method as in appellants' claim 14 on appeal,

                   "means for determining a location separation distance between

                   generating a deviation signal of said second location with

                   It follows from the foregoing that we will not sustain the
