              Appeal No. 2002-1207                                                                   Page 3                 
              Reissue Application No. 09/103,321                                                                            
              (page 5 of answer, first paragraph).  Based on this rationale, the examiner concludes                         
              that "the instant claims are broader in scope than the original claims because they                           
              contain within their scope a conceivable process which would not have infringed the                           
              original patent" (id.).  The examiner further explains at page 6 of the answer that "it is                    
              maintained that the instant claims are broader than the original patented claims                              
              because reversing the operation of the contracting and expanding arrangements                                 
              presents a conceivable process, in at least one respect, which would not have infringed                       
              upon the original patent" (second paragraph).                                                                 
                     We concur with the statement made by the examiner at page 4 of the answer                              
              that "the patented claims, containing a clear ambiguity, must be interpreted in light of                      
              the original disclosure and/or specification" (page 4, last paragraph), i.e., in any                          
              infringement action the patented claims would be interpreted in light of the specification                    
              to define the apparatus intended by appellant and presently claimed.  Hence, although                         
              the patented claims may be construed to also define the more complicated apparatus                            
              referred to by the examiner, the claims would also embrace the apparatus defined in                           
              the claims of the reissue application on appeal.  Hence, the instant claims would                             
              infringe the patented claims and, accordingly, are not broader in scope than the                              
              patented claims in any respect.
