                        This is a decision on the appeal under 35 U.S.C. § 134 from the examiner’s                                         
                rejection of claims 4 and 7-10.  Pending claims 1-3, 5 and 6 have been indicated by the                                    
                examiner to contain allowable subject matter.                                                                              
                        The disclosed invention pertains to a method and apparatus for authenticating                                      
                documents of value.  The invention uses a light emitting diode (LED) which emits ultra-                                    
                violet (UV) radiation in a wavelength range at which non-genuine documents have a                                          
                different reflectivity than genuine documents.
