             Appeal No. 1997-2656                                                                                     
             Application No. 07/907,472                                                                               


             above.  Appellants argue that the rejection relies on the obviousness of implementing                    
             the invention after the combination of the APA and Yoshida.  (See Request for                            
             Rehearing at page 3.)  We agree with the appellants, but do not find this persuasive in                  
             light of the suggestion of Yoshida concerning the user understandable format of the                      
             display.  Appellants argue that the rejection fails to consider the nonobviousness of the                
             combination, which in not suggested by either reference.  (See Request for Rehearing                     
             at page 3.)  We do not find this argument persuasive since appellants have not                           
             identified why it would not have been obvious to have the display of both types of                       
             information in a user understandable formats as is suggested by Yoshida.                                 
                    Appellants argue that the examiner has not demonstrated any prior art                             
             motivation for the combination of references.  (See Request for Rehearing at page 4.)                    
             We disagree with appellants, as discussed above.  Appellants argue that a posteriori                     
             ease of implementation is not equivalent to a priori obviousness of the implementation.                  
             We agree with appellants' distinction, but do not find this argument persuasive.                         
                    In item (3) with respect to the separate patentability of claim 3, appellants argue               
             that "numerous references to the patentable differences between the dependent claims                     
             and the parent claims" are present in the brief.  Here, this amounts to merely                           
             pointing out differences in what the claims cover and not why the claims are separately                  
             patentable.  We note that an argument that a claim is different from another claim in its                
             content is a requirement to avoid double patenting, but does not amount to an
