              Appeal No. 2005-2642                                                                                            
              Reexamination Control No. 90/005,841                                                                            

                      produce the objective of the applicant's invention.  In re Gurley, 27 F.3d                              
                      551, 553 (Fed. Cir. 1994).  A statement that a particular combination is not                            
                      a preferred embodiment does not teach away absent clear                                                 
                      discouragement of that combination.  In re Fulton, 391 F.3d at 1199-1200.                               
              Regarding the examiner’s motivation for combining the teachings of Bodie with those of                          
              Mukherjee as modified above in view of Musmanno, we agree that it would have been                               
              obvious for a bank to want to pay some or all of the costs of its inflation-indexed deposit                     
              accounts by investing in inflation-indexed annuities of the type described in Bodie, if and                     
              when they should become available, with the principal component of the annuity being                            
              paid out over a plurality of iterations over the term, as required by claim 31, and with the                    
              accrual component also being paid out over a plurality of iterations over the term (not                         
              required by claim 31).  Appellant has not explained why claim 31 would be patentable                            
              over Mukherjee, Musmanno, and Bodie even if Bodie’s disclosure of inflation-indexed                             
              annuities is considered to be enabling.  We are therefore affirming the rejection of claim                      
              31 based on those references.                                                                                   
                      Claim 33, which depends on claim 24, specifies that the “index” recited in that                         
              claim “corresponds generally to the consumer price index.”  The examiner has rejected                           
              this claim on the cited references in two different ways, both of which are persuasive.                         
              First, he argues that the claim is unpatentable over the combined teachings of                                  
              Mukherjee and Musmanno in the manner discussed in the rejection of claim 24,                                    
              asserting that Mukherjee discloses relying on the “consumer price index” at page 51,                            

                                                             38
