Appeal No. 95-3933 Application No. 08/063,206 is disclosed, or rendered obvious, by the applied reference. In re Stempel, 241 F.2d 755, 759, 113 USPQ 77, 81 (CCPA 1957). In the present case, the examiner expressly acknowledges that "Brown et al[.] do not teach reacting an alkoxy silane with water in the presence of an acidic condensation catalayst [sic], as recited in step (I) of instant claim 1" (page 3 of Answer). Since the examiner relies on Brown for claimed steps (IV)-(VI), and makes no argument that the Rule 131 Affidavit does not show reduction to practice of claimed steps (IV)-(VI) prior to the effective date of Brown, it can be seen that the Affidavit establishes priority of invention for that portion of the presently claimed invention that is disclosed by Brown. Also, based on the Burzynski disclosure, we find that claimed steps (I)-(III), not requiring alcohol as a reactant, would have been an obvious modification of the reaction shown in the Affidavit to one of ordinary skill in the art. In re Stempel, 241 F.2d at 759, 113 USPQ at 81; In re Clarke, 356 F.2d 987, 992, 148 USPQ 665, 670 (CCPA 1966). Since we agree with appellants that the Rule 131 Affidavit of November 21, 1994, effectively removes the reference to Brown as prior art, it logically follows that we must reverse the examiner's rejection under 35 U.S.C. § 103 over Brown in view of Burzynski. -4-Page: Previous 1 2 3 4 5 6 NextLast modified: November 3, 2007
