          identical cassette bin is able to accommodate a plurality of                
          different types of cassettes, whereas in Kulakowski, each                   
          cassette bin may be specifically designed to hold a particular              
          mix of cassettes, but each cassette bin is not substantially                
          identical and designed to accommodate a plurality of different              
          types of cassettes."  (Appeal Br. at 10.)                                   


               In deciding obviousness, “[a]nalysis begins with a key                 
          legal question -- what is the invention claimed?”  Panduit                  
          Corp. v. Dennison Mfg. Co., 810 F.2d 1561, 1567, 1 USPQ2d                   
          1593, 1597 (Fed. Cir. 1987).  Here, independent claims 1 and 4              
          specify in pertinent part the following limitations: "a                     
          cassette accommodating portion including a plurality of                     
          accommodating units each having a plurality of substantially                
          identical cassette bins, each individual cassette bin being                 
          adapted to accommodate a plurality of different types of                    
          cassettes housing different types of recording media having                 
          different types of recording formats. . . ."  Accordingly,                  
          limitations require inter alia substantially identical
