          Appeal No. 2000-0132                                                        
          Application No. 08/934,791                                                  


          F.2d at 1280, 193 USPQ at 148.  According to Orita, there is no             
          correctable error in failing to prosecute the divisional                    
          application on the non-elected inventions identified by the                 
          examiner in the restriction requirement.  Id.                               
               In the present case, no formal restriction requirement of              
          claims drawn to a combination of a separating agent and a                   
          chromatographic column was ever imposed by the examiner, or                 
          acquiesced by the appellants, since they were not presented in              
          the appellants’ original application.  Thus, it cannot be argued            
          that the appellants’ failure to file a divisional application to            
          such subject matter was a deliberate act and not an error under             
          Section 251.  Compare In re Doyle, 293 F.3d 1355, 63 USPQ2d 1161            
          (Fed. Cir. 2002).                                                           
               It is important to recognize that Section 251 is a remedial            
          statute which must be interpreted liberally.  Weiler, 790 F.2d at           
          1579, 229 USPQ at 675.  “Although attorney error is not an open             
          invitation to reissue in every case . . . the purpose of the                
          reissue statute is to avoid forfeiture of substantive rights due            
          to error made without intent to deceive.”  Scripps Clinic                   
          & Research Found. v. Genentech, Inc., 927 F.2d 1565, 1575, 18               
          USPQ2d 1001, 1009 (Fed. Cir. 1991).  Accordingly, we decline to             
          extend any per se or mechanical rule against reissue where the              
                                          7
