              Appeal No. 2000-0630                                                                                           
              Application No. 07/780,717                                                                                     

                      Appellant relies upon the following additional reference:                                              
              Pähler et al. (Pähler), “Characterization and Crystallization of Core Streptavidin,” J. Biol.                  
              Chem., Vol. 262, No. 29, pp. 13933-13937 (October 1987)                                                        
                                               PROCEDURAL MATTERS                                                            
                      There is some confusion regarding the issues before us for consideration.  The                         
              Examiner’s Answer refers (improperly) to two previous office actions for the statement of                      
              the rejection (paper no. 44, the final rejection; and paper no. 42, a non-final rejection).                    
                      In paper no. 42, claims 39 through 45, 47 through 54, 56 through 58 and 60 through                     
              65 were rejected under 35 U.S.C. § 103(a) as unpatentable over Hendrickson, Sano,                              
              Kenten, Shoemaker, Tolman, Lowenadler and Meade; in addition, claims 39 through 45,                            
              47 through 54, 56 through 58 and 60 through 65 were rejected under 35 U.S.C. § 103(a)                          
              as unpatentable over Rodwell, Hendrickson, Sano, Kenten, Shoemaker, Tolman,                                    
              Lowenadler and Meade.                                                                                          
                      In their response to paper no. 42, appellants submitted new claims 66 though 68                        
              (paper no. 43).                                                                                                
                      In paper no. 44, the examiner maintained “[a]ll the rejections set forth in the last                   
              office action.”  In addition, new claims 66 and 67 were included in the rejection based on                     
              the combined teachings of Hendrickson, Sano, Kenten, Shoemaker, Tolman, Lowenadler                             
              and Meade.  Finally, new claim 68 was rejected under 35 U.S.C. § 103(a) as unpatentable                        
              over Hendrickson and Sano.                                                                                     


                                                             3
