Appeal No. 2003-0052 Application No. 09/782,268 Under these circumstances, we share the examiner’s conclusion that it would have been prima facie obvious for an artisan to practice the method of Fifolt at pressures of the type here claimed (e.g., see appealed claims 1-4 and 7) which are above atmospheric pressure. In support of his contrary view, the appellant states that, “[i]n Example 1 (col. 2, lines 46-57), the effluent from the reaction was trapped in a metal trap cooled with dry ice and ethanol” and that “[t]his is considered vacuum conditions” (brief, page 2). However, the appellant has proffered no evidence in support of his last quoted conclusion. Further, as noted by the examiner in his answer, the conditions in patentee’s trap would not create a vacuum in the reaction zone unless a closed system were utilized and the Fifolt reference contains no disclosure of a closed system. For these reasons, we discern no persuasive merit in the appellant’s argument that the examiner has failed to establish a prima facie case of obviousness. As further support for his nonobviousness position, the appellant refers to data in the subject specification which is characterized as showing unexpected results that rebut a prima facie case of obviousness. This data appears on specification 4Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
