                 Appeal 2006-2961                                                                                         
                 Application 09/745,390                                                                                   
                                                                                                                         
                         Pro, Inc., 425 U.S. 273, 189 USPQ 449 (1976)] and                                                
                         Anderson's-Black Rock[, Inc. v. Pavement Salvage Co.,                                            
                         396 U.S. 57, 163 USPQ 673 (1969)] are illustrative—a court                                       
                         must ask whether the improvement is more than the predictable                                    
                         use of prior art elements according to their established                                         
                         functions.                                                                                       
                 KSR, 127 S. Ct. at 1740, 82 USPQ2d at 1396.  If the claimed subject matter                               
                 cannot be fairly characterized as involving the simple substitution of one                               
                 known element for another or the mere application of a known technique to                                
                 a piece of prior art ready for the improvement, a holding of obviousness can                             
                 be based on a showing that “there was an apparent reason to combine the                                  
                 known elements in the fashion claimed.”  Id., 127 S. Ct. at 1740-41,                                     
                 82 USPQ2d at 1396.  Such a showing requires “some articulated reasoning                                  
                 with some rational underpinning to support the legal conclusion of                                       
                 obviousness. . . . [H]owever, the analysis need not seek out precise teachings                           
                 directed to the specific subject matter of the challenged claim, for a court                             
                 can take account of the inferences and creative steps that a person of                                   
                 ordinary skill in the art would employ.”  Id., 127 S. Ct. at 1741, 82 USPQ2d                             
                 at 1396 (quoting In re Kahn, 441 F.3d 977, 987, 78 USPQ2d 1329, 1336                                     
                 (Fed. Cir. 2006)).                                                                                       
                         If the Examiner’s burden is met, the burden then shifts to the                                   
                 Appellants to overcome the prima facie case with argument and/or evidence.                               
                 Obviousness is then determined on the basis of the evidence as a whole and                               
                 the relative persuasiveness of the arguments.  See In re Oetiker, 977 F.2d                               
                 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992).                                                       
                         Regarding representative claim 1, the Examiner's rejection essentially                           
                 finds that Park discloses a mobile station with every claimed feature except                             
                 for a self-powered information entry part.  The Examiner cites Halperin as                               

                                                            4
