                Appeal 2006-3235                                                                                
                Reexamination Control No. 90/006,696                                                            

           1                 amendment to his patent and a new claim or claims                                  
           2                 thereto, in order to distinguish the invention as claimed                          
           3                 from the prior art cited under the provisions of section 301                       
           4                 of this title, or in response to a decision adverse to the                         
           5                 patentability of a claim of a patent.  No proposed amended                         
           6                 or new claim enlarging the scope of a claim of the patent                          
           7                 will be permitted in a reexamination proceeding under this                         
           8                 chapter.                                                                           
           9           35 U.S.C. § 305 (1982).                                                                  
          10                 Appellant therefore had an opportunity during                                      
          11           reexamination in the PTO to amend his claims to correspond                               
          12           with his contribution to the art.  The reasons underlying the                            
          13           PTO's interpretation of the claims in reissue proceedings                                
          14           therefore justify using the same approach in reexamination                               
          15           proceedings.                                                                             
          16    Yamamoto, 740 F.2d at 1572, 222 USPQ at 936-37.  In this reexamination                          
          17    proceeding, the patent owner had an opportunity to amend the patent claims                      
          18    or propose new claims in response to the rejection given in the First Action                    
          19    but elected not to do so.  This opportunity to amend continued for about                        
          20    seven weeks, at which time the ‘857 patent expired.                                             
          21    D.  Conclusion                                                                                  
          22           In accordance with Am. Acad. and Yamamoto, we will give Claim 11                         
          23    its broadest reasonable interpretation consistent with the disclosure of the                    
          24    ‘857 patent.                                                                                    
          25                                                                                                    
          26              ISSUE 2 -- IS THE RELEVANT FIELD OF ENDEAVOR

          29    A.  Facts (many of which are also relevant to Issue 3, involving claim                          
          30    interpretation)
