          Interference No. 103,036                                                    


          such error as is encompassed by 35 U.S.C. § 251.  To the extent             
          that motion no. 3 raises the same grounds for unpatentability as            
          raised by the party Cataldi et al.’s motion no. 24, motion no. 3            
          is denied for the reasons set forth in the Final Decision (Paper            
          No. 802) with respect to the party Cataldi et al.                           
                    To the extent that motion no. 3 urges that the party              
          Burroughs et al.’s claims are unpatentable as drawn to subject              
          matter which was abandoned, dedicated, or disclaimed, the motion            
          is denied.   As the moving party, the party Wang et al. has the             
          burden of proof by a preponderance of the evidence on the motion.           
          Kubota v. Shibuya, 999 F.2d 517, 519, n.2, 27 USPQ2d 1418, 1420,            
          n.2 (Fed. Cir. 1993).  The party Wang et al. has not sustained              
          its burden of proof since it has not analyzed each of the reissue           
          claims vis-à-vis each claim canceled during ex parte prosecution            
          of the party Burroughs et al.’s involved patent.  Nonetheless we            
          have reviewed the claims canceled during ex parte prosecution and           
          we are not persuaded that the party Burroughs et al. has                    
          attempted in its reissue application to recapture subject matter            
          canceled during the original prosecution of its patent.  We agree           
          with the party Burroughs et al. that its reissue application                
          contains claims, which are narrower or materially different from            
          the canceled claims.                                                        
                    For the foregoing reasons, motion no. 3 is denied.                


                                        -13-
