          Appeal No. 1997-2380                                                        
          Application No. 08/121,809                                                  


          information is a bad or good frame of information is not (as                
          contended by the Examiner) the same as switching between modes              
          of operation (as in Fletcher)” based upon a single threshold                
          value.  As indicated supra, the examiner has acknowledged that              
          Gould does not disclose the use of two thresholds in the                    
          determination of bad frames.                                                
               In summary, the obviousness rejection of claims 1 through              
          14 is reversed because neither Gould nor Fletcher teaches or                
          would have suggested to one of ordinary skill in the art the                
          claimed switching between two bit correction thresholds based               
          upon the erasure of at least one bad frame of information.                  
                                      DECISION                                        
               The decision of the examiner rejecting claims 1 through                
          14 under 35 U.S.C. § 103 is reversed.
