          Appeal No. 1997-1011                                                       
          Application No. 08/250,631                                                 

               claims of the group are believed to be separately                     
               patentable.  Merely pointing out differences in what                  
               the claims cover is not an argument as to why the                     
               claims are separately patentable  (underlining added for              
          Therefore, we will consider the claims according to the following          
          groups, (1) claims 1 through 10, 14, 15, and 19 through 21,                
          (2) claims 11 through 13, (3) claims 16 and 17, and (4) claims 18          
          and 22, with claims 1, 11, 16, and 18 as representative.                   
               We have carefully considered the claims, the applied prior            
          art references, and the respective positions articulated by                
          appellant and the examiner.  As a consequence of our review, we            
          will reverse the obviousness rejection of claims 1 through 22.             
               Appellant's sole argument with respect to claim 1 (Reply              
          Brief, pages 1-2) is that neither Takarada nor Niioka discloses            
          transmitting icons which display the source information, such as           
          a network identifier, station call letters, or a program title.            
          The examiner asserts (Answer, page 3) that it would have been              
          obvious in view of the teachings of Niioka to use network                  
          identifiers as Takarada's character data.                                  
               Takarada discloses (translation, page 4-5) a transmitter              
          (transmission circuit 2), which transmits communication signals            
          (character data Vd and video signals Vf), a receiver (antenna              
          11), stripping circuitry (processing circuit 13, which separates           
          video signals Vf from the remaining signals V o), and a display
