          Appeal No. 2001-1596                                                        
          Application 09/296,102                                                      

          paragraph 7 of the new reissue declaration (filed Jan. 4, 2000)             
          that this language “was erroneously included in claim 1 [and] was           
          not necessary either for a complete definition of our invention             
          or for distinguishing the prior art.”  Thus, the application                
          seeks to enlarge the scope of claims 1 to 14 of the patent, and             
          was properly filed within two years from the grant of the patent,           
          as provided by the fourth paragraph of 35 U.S.C. § 251.  However,           
          the examiner considers claims 1 to 14 to be unpatentable under              
          § 251 because they are “an improper recapture of broadened                  
          claimed subject matter surrendered in the application for the               
          patent upon which the present reissue is based” (answer, page 3).           
          Specifically, the examiner takes the position that (answer, pages           
          3 to 4):                                                                    
               The record of the application for the patent shows that the            
               broadening aspect (in the reissue) relates to subject matter           
               that applicant previously surrendered during the prosecution           
               of the application.  Accordingly, the narrow scope of the              
               claims in the patent was not an error within the meaning of            
               35 U.S.C. § 251, and the broader scope surrendered in the              
               application for the patent cannot be recaptured by the                 
               filing of the present reissue application.                             
                    The patent claims 1-14 were allowed on the basis of               
               Examiner’s Statement of Reason(s) for Allowance, . . .                 
               [quoted supra].                                                        
                    Claim 1, as presented in this reissue application,                
               seeks to broaden the coverage by the removal of the                    
               limitation of, “the third axis [is] disposed inside [of]               
               a triangle defined by the first, second and fourth axes                
               viewed on end.”                                                        
                    Since applicant did not present on the record a counter           
                                          4
