Appeal No. 2006-0900 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 et al. 5,902,863 May 11, 1999 (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. -2-Page: Previous 1 2 3 4 5 6 7 NextLast modified: November 3, 2007
