          Appeal No. 2005-0986                                                        
          Application No. 09/727,904                                                  

          same entity.  We note, again, that, unlike independent claims 1,            
          16, and 17, claims 18-20 do not specify the particular technique            
          employing a blinded version of a first ciphertext portion of a              
          signed ciphertext.                                                          
               Thus, while we have not sustained the rejection of claims 1-           
          17 under 35 U.S.C. § 103, we will sustain the rejection of claims           
          18-20 under 35 U.S.C. § 103 because appellants have not                     
          convincingly shown any error in the examiner’s position.                    
               The examiner’s decision is affirmed-in-part.                           
               No time period for taking any subsequent action in                     
          connection with this appeal may be extended under 37 CFR                    
          § 1.136(a)(1)(iv).                                                          
                                  AFFIRMED-IN-PART
