Appeal No. 2001-1572 Application 08/939,569 interface which has the properties recited in the last clause of the independent claims on appeal. The examiner is also incorrect in relying on a per se rule of obviousness that a change in size is not patentable. The examiner should consider the specific recitations of a claim and provide an evidentiary basis which supports the position that the specific recited size would have been obvious over the applied evidence. The examiner cannot simply find obviousness and seek to shift the burden to appellants to show secondary considerations of non-obviousness. Since we do not sustain the rejection of any of the independent claims on appeal, we also do not sustain the rejection of any of the remaining claims which depend therefrom. We note for the record, however, that the examiner’s reliance on what is deemed well known in the art in rejecting the dependent claims on appeal is insufficient to establish a prima facie case of obviousness. -7-Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
