                Appeal  2007-1119                                                                            
                Application 10/200,207                                                                       
                      subject[ing] the original patent to the twenty-year patent term                        
                      under 35 U.S.C. § 154(a)(2).                                                           
                (Reissue Declaration at 2.)  The practical effect of having filed Continued                  
                Prosecution Applications is that the term of the 219 patent expires 20 years                 
                from 7 May 1987, i.e., on 7 May 2007, which is five days after the date on                   
                which oral argument was held.  See 37 C.F.R. § 1.53(d) (1998)4.  In                          
                contrast, Applicants assert that they are entitled to "the full term of the                  
                original patent," which they argue should have been 17 years from the date                   
                of issue.                                                                                    

                                                                                                            
                4 37 C.F.R. § 1.53(d) reads in most relevant part:                                           
                      (7) A request for an application under this paragraph is the                           
                      specific reference required by 35 U.S.C. 120 to every                                  
                      application assigned the application number identified in such                         
                      request.  No amendment in an application under this paragraph                          
                      may delete this specific reference to any prior application.                           
                37 C.F.R. § 1.53(d)(7) (1998) (emphasis added).                                              
                      This provision was explained in the Notice of Final Rule Making                        
                issued in 1997 in the following words:                                                       
                      an application under § 1.53(d) cannot be amended to delete the                         
                      specific reference to the prior application, as well as the specific                   
                      reference to any application to which the prior application                            
                      contains a specific reference under 35 U.S.C. 120, 121,                                
                      and 365(c).  As an application under § 1.53(d) will also contain                       
                      a specific reference to at least one other application under                           
                      35 U.S.C. 120, 121, and 365(c), the expiration date under                              
                      35 U.S.C. 154(b)(2) of any patent issuing from the application                         
                      under § 1.53(d) will be based upon the filing date of the prior                        
                      application (or the earliest application to which the prior                            
                      application contains a specific reference under 35 U.S.C. 120,                         
                      121, and 365(c)).                                                                      
                62 Fed. Reg. 53145 (10 October 1997) (emphasis added).                                       
                                                     8
