          Application No. 10/368,915                                                  

               passing a liquid to be purified through a bed of particles             
          of said silicone derivatized macromolecule on a particular                  
          support or through a separation membrane having said silicone               
          derivatized macromolecule supported thereon.                                
               The examiner relies upon the following references as                   
          evidence of obviousness:

          (Dvornic)                                                                   
          Neumann-Rodekirch et al. 196 21 741 A1   Dec. 4, 1997                       
          (Neumann)                                                                   
          (German Patent)                                                             
               Appellants’ claimed invention is directed to a purification            
          process which entails providing a silicone derivatized                      
          macromolecule of the recited group on a particulate support or              
          separation membrane, and passing a liquid to be purified through            
          the support or separation membrane.  According to appellants,               
          the claimed support or separation membrane comprising a silicone            
          derivatized macromolecule is “useful for separating chiral                  
          components from biological or chemical processes in pharma-                 
          ceutical, biopharmaceutical and/or chemical process                         
          applications” (page 2 of Brief, last paragraph).                            
               Appealed claims 39-41, 43, 45, and 46 stand rejected under             
          35 U.S.C. § 103 as being unpatentable over Neumann in view of               
          Dvornic.
