             Appeal No. 2006-0323                                                                                   
             Application No. 10/088,727                                                                             


             Appellants respond that this case should be remanded to the examiner so that                           
             appellants are given a full and fair opportunity to respond to the new references                      
             and definitions cited by the examiner.  Appellants reiterate their position that Jost                  
             fails to teach the generation of a real image onto a display surface on the                            
             instrument panel of the vehicle via a projection unit arranged on the vehicle roof                     
             as claimed.  Appellants substantially repeat the arguments made in the main brief                      
             [reply brief].                                                                                         
                    When this application was previously on appeal before us, we determined                         
             that a remand of this application to the examiner was appropriate.  In particular,                     
             the remand stated the following:                                                                       
             We will remand this application to the examiner as requested                                           
                           by appellants.  The patentability of the claims on appeal                                
                           cannot be determined without a clear definition of what                                  
                           is meant by the term “real image.”  The definition of this                               
                           term in Wikipedia could possibly suggest that a real                                     
                           image is present at mirror 11 or windshield 1 of Jost.  An                               
                           additional question would then arise as to whether either                                
                           of these surfaces can be considered to be “a display                                     
                           surface” within the meaning of the claims on appeal.                                     
                           These questions need to be argued by appellants and the                                  
                           examiner in order for us to have an appropriate record to                                
                           decide this appeal.  The answer to these questions could                                 
                           eliminate the need to rely on Kleinschmidt to teach the                                  
                           generation of real images.  Therefore, we remand this                                    
                           application to the examiner for a consideration of                                       
                           whether a real image within the meaning of the claims is                                 
                           generated upon surfaces 1 or 11 of Jost and whether                                      
                           surfaces 1 or 11 of Jost can meet the recitation of a                                    
                           “display surface” in the claims.                                                         
                                                                                                                   
             The examiner should address these questions in the form of a                                           
                           supplemental examiner’s answer which fully elaborates                                    
                           on these questions.  Appellants will be given the usual                                  
                                                         4
