                Appeal  2007-1119                                                                            
                Application 10/200,207                                                                       
                      We begin our consideration of the merits of this appeal by inspecting                  
                the language of the statute for its plain meaning.  Medrad, Inc. v. Tyco                     
                Healthcare Group LPC, 466 F.3d 1047, 1051, 80 USPQ2d 1526, 1528 (Fed                         
                Cir. 2006) (reh'g and reh'g en banc denied) ("If the words [of the statute] are              
                unambiguous, no further inquiry is usually required." (citation omitted)).                   
                Section 251 states that if the Director reissues the patent, it shall be reissued            
                "for the unexpired part of the term of the original patent."  These words are                
                plain, direct, and unambiguous.  The term of the original patent is set upon                 
                issuance, and, by the terms of the statute, reissue cannot operate to extend                 
                that term.  As the MPEP puts it, "[t]he maximum term of the original patent                  
                is fixed at the time the patent is granted."  MPEP § 1405, 8th Ed., Rev. 5.                  
                While circumstances can be imagined under which patent term is shortened                     
                by requirements to disclaim term, e.g., to remove a rejection for                            
                obviousness-type double patenting, the expansion of patent term by reissue                   
                is foreclosed by the plain language of the statute.                                          
                      Based on our review of the record, we find that the Examiner,                          
                following the MPEP, simply applied the plain language of the statute in                      
                holding that the error asserted by Applicants was not an error correctable by                
                reissue.  Accordingly, we reject Applicants' argument that they have not                     
                been accorded adequate notice of the basis of the Office's position.                         
                      We therefore AFFIRM the Examiner's rejection on the same basis as                      
                the Examiner: section 251 expressly forbids reissue expanding the term of a                  
                reissued patent.5                                                                            

                                                                                                            
                5 We also note that the reissue application was filed 23 July 2003, more than                
                two years after the 19 June 2001 issue date of the 219 patent.  It is arguable,              
                                                     9
