                Appeal 2007-0725                                                                                
                Reexamination Control 90/006,785                                                                
                Patent 5,073,484                                                                                
                points out that Deutsch was relied upon by the Examiner in the prosecution                      
                of the 06/467,229 Application.  (Br. at 14).                                                    
                       Patentee acknowledges that 35 USC § 303(a) does not preclude the                         
                finding of a substantial new question of patentability where a reference was                    
                previously cited or considered by the Office.  Patentee’s argues, however,                      
                that “[i]t is clear that Deutsch was viewed in the same light in the earlier                    
                prosecution as the Examiner places on it in the current reexamination.” (Br.                    
                at 14).                                                                                         
                       In support of its position, Patentee directs us to a 7 September 1984                    
                Office Action, rejecting claim 10 of 06/467,229.  (Br. at 14, directing us to                   
                App. 4).                                                                                        
                       However, as noted by the Examiner, Deutsch was not cited against the                     
                presently rejected claims.  (Answer at 11).  While Patentee takes the position                  
                that previous claim 10 “included the steps of providing reaction zones,                         
                flowing through reaction zones, and detecting the presence, just as in Claims                   
                22 and 23.” (Br. at 14), a comparison of claim 10 with the presently rejected                   
                claims reveals a difference in claim scope.  For example, claim 10 requires                     
                “spaced reaction zones” while the claims under rejection require “one or                        
                more reaction zones.”  Claim 10 is of narrower scope at least in that it                        
                requires multiple reaction zones.                                                               
                       Even more to the point perhaps, is that, in the 06/467,229 prosecution,                  
                Deutsch was not relied upon for the same reason the examiner now relies                         
                upon it.  In particular, Deutsch was relied upon, as a secondary reference, for
