            Appeal 2007-0635                                                                               
            Application 10/176,598                                                                         

                         [T]here is no disclosure or suggestion that Ward could keep track of              
                  the "total amount of time" a user plays back a file, as stated by the Examiner           
                  in the Final Rejection, because "the total amount of times a user plays back a           
                  media file" is not the same thing as in Claim 17 of keeping track of the "total          
                  duration of time" a media file is played back. Keeping track of whether a                
                  media file was played back of not (see Ward, col. 8, lines 28-40) where                  
                  playback of media files in [sic] performed serially in view of a play list, does         
                  not disclose or suggest that such media files can be played back multiple                
                  times, or such multiple plays are capable of being tracked, without resetting            
                  a play list.                                                                             
            Appeal Br. 9.                                                                                  
            The level of ordinary skill in the pertinent art.                                              
            9. Neither the Examiner nor Appellants have addressed the level of ordinary                    
            skill in the pertinent art of electronic commerce. We will consider Ward as                    
            representative of the level of ordinary skill in the art. See Okajima v. Bourdeau,             
            261 F.3d 1350, 1355, 59 USPQ2d 1795, 1797 (Fed. Cir. 2001) (“[T]he absence of                  
            specific findings on the level of skill in the art does not give rise to reversible error      
            ‘where the prior art itself reflects an appropriate level and a need for testimony is          
            not shown.’”).                                                                                 
            Secondary considerations.                                                                      
            10. Appellants presented no evidence of secondary considerations of non-                       
            obviousness for our consideration.                                                             

                  C. PRINCIPLES OF LAW                                                                     
                  We incorporate herein the Principles of Law set forth in the Principles of               
            Law section for claims 2, 4-9, and 12-16 above.                                                
                                                    22
