                Appeal 2006-2328                                                                                       
                Application 10/131,049                                                                                 

                       Analysis                                                                                        
                       The Examiner's reasoning from the Advisory Action that it would have                            
                been obvious to modify Arai to include vertical countdown circuitry is not                             
                persuasive because the Examiner has provided no evidence to support the                                
                finding that generating replacement synchronizing signals was well known, as                           
                discussed in connection with claim 58.                                                                 
                       The Examiner interprets the step of "generating separate reference                              
                horizontal and vertical synchronous signals" to read on selecting horizontal                           
                and vertical synchronous signals from the Sync on G input when they are                                
                missing from the VS or C. Sync/HS inputs.  This interpretation is                                      
                unreasonable.  We interpret "generating separate reference horizontal and                              
                vertical synchronous signals" to require "generating" in the sense of creating a                       
                replacement signal, not just selecting existing synchronous signals.  See                              
                In re Scroggie, 170 Fed. Appx. 132, 135 (Fed. Cir. 2006) (nonprecedential)                             
                ("The term 'generating page data' means that the page data is 'generated,' not                         
                merely selected.'").  Moreover, there is no guarantee that there will be                               
                synchronizing signals present at the Sync on G input when they are missing                             
                from the VS or C. Sync/HS inputs, whereas "generated" signals will be.  The                            
                Examiner errs in finding that Arai teaches generating vertical reference                               
                signals and providing such signals to a synchronous signal processor.                                  
                       Accordingly, we find that Arai does not disclose or suggest to one of                           
                ordinary skill in the art the steps of "if said at least one input synchronous                         
                signal is not received, generating separate reference . . . vertical synchronous                       
                                                        - 26 -
