                Appeal 2006-3092                                                                                   
                Application 10/601,738                                                                             
                       From our review of the Examiner’s rejection, we conclude that the                           
                Examiner has set forth a prima facie case of obviousness of the invention as                       
                recited in independent claim 1.  Therefore, we look to Appellants’ Briefs to                       
                show error in the proffered prima facie case.                                                      
                       Appellants’ main contention is that it would not have been obvious to                       
                one skilled in the art at the time of the invention to have combined the                           
                teachings of Kurita and King to achieve the invention as recited in                                
                independent claim 1 (Br. 10-11).  Specifically, Appellants argue that (i)                          
                Kurita and King, when considered as a whole, do not suggest the desirability                       
                and thus the obviousness of modifying Kurita in the manner taught by King,                         
                and (ii) modifying Kurita in the manner taught by King renders Kurita                              
                unsatisfactory for the intended purpose and consequently, there is no                              
                suggestion or motivation to make the proposed combination (Br. 11 and                              
                Reply Br. 2).  Appellants' additionally contend that it would not have been                        
                obvious to one of ordinary skill in the art at the time of the invention to                        
                combine the plural interfaces of King in the control system of Kurita since                        
                Kurita discloses a problem using a single control to control multiple devices                      
                in that an operator's control efficiency is low as a result of having to navigate                  
                the switches/buttons which are respectively associated with the devices                            
                (Reply Brief 2).  Therefore, Appellants’ argue that it would not have been                         
                obvious to one of ordinary skill in the art at the time the invention was made                     
                to use plural controls to control plural devices at the same time due to this                      
                problem of low operator efficiency associated with using a single control to                       
                control devices at a single time.                                                                  




                                                        7
