Appeal No. 96-3149 Application 08/305,428 We do not agree with this conclusion. We understand the phrase “minimum air flow” to require that some air flow be permitted when the valve is in its lowered position. Since claims 13 and 14 recite means to allow a minimum air flow when the valve is in the lowered position, and Binder does not allow any air flow when its valve is in the lowered position, a prima facie case of obviousness is lacking and we will not sustain this rejection. Dependent claims 17 and 18 stand rejected under 35 U.S.C. § 103 on the basis of Binder and Ballard. The latter reference is cited by the examiner for its teaching of “means 29 outside of the duct for moving the valve between open and closed positions” (Answer, page 4). Be that as it may, Ballard does not alleviate the shortcoming in Binder which was discussed above with regard to the rejection under Section 102. That being the case, the combined teachings of the two references fail to establish a prima facie case of obviousness with respect to claims 17 and 18, and we will not sustain the Section 103 rejection. 4Page: Previous 1 2 3 4 5 6 NextLast modified: November 3, 2007
