          Appeal No. 97-0609                                                          
          Application 08/480,106                                                      


          appears that the examiner has not set forth a prima facie case of           
          obviousness of the subject matter of independent claims 1 and 5             
          on appeal in light of the teachings and suggestions of Missios,             
          the sole reference relied upon.                                             
               Our detailed study of this reference also leads us to                  
          conclude our agreement with appellants’ basic position generally            
          expressed at pages 14 and 15 of the principal Brief on appeal               
          that such above noted feature set forth in both claims on appeal            
          is not taught or suggested in the reference relied upon by the              
          examiner.  The operation of the sequence of blocks greater than             
          block D3 in Fig. 1 of Missios does not appear to us to fuction in           
          the manner required by the noted portion of claims 1 and 5 on               
          appeal, since when a no error condition is obtained according to            
          the flow diagram in Fig. 1, the sequencing of instructions does             
          not next continue to occur at the instruction cycle time rate at            
          which the retry was determined to be successful.                            
               Turning lastly to the subject matter of independent claim 11           
          on appeal, again, we note that the statement of the rejection               
          beginning at page 3 of the answer does not detail the particulars           
          of this claim, the pertinent portion of which relates to the                
          determination of an error being done by iteratively increasing an           



                                          4
