          Appeal No. 95-3535                                                           
          Application No. 08/095,033                                                   

                                       OPINION                                         
               We will not sustain the rejection of claims 32 through 42               
          under 35 U.S.C. '  103 because, in our view, the examiner has not            
          set forth a prima facie case of obviousness.                                 
               The examiner takes the position that since appellants admit,            
          at page 3 of the specification, that it was known to convert data            
          of upper level release systems to data of lower level release                
          systems where the operation is being performed at the lower level            
          release system, the only difference between the instant claimed              
          invention and that which is admitted to have been well known is              
          that, in the former, “the conversion is installed in the later               
          version computer instead of in the earlier version computer”                 
          [page 3-answer].                                                             
               Identifying the sole issue, with which we agree,  as whether            
          it would have been obvious to install the conversion circuit and             
          have the conversion done at the later version computer (upper                
          level) instead of at the earlier version computer, the examiner              
          reaches the conclusion, erroneously, in our view, considering the            
          applied prior art, that it would have been obvious “to have the              
          conversion done at the newly relaesed [sic, released] system                 
          because the old system, then, do not have to be recalled and                 
          modified” [page 4-answer].                                                   
               As simple as the solution may appear in hindsight, nothing              
          in the prior art identified at pages 2-3 of the specification                
          suggests performing the conversion at the later version level in             


                                           3
