Even assuming arguendo that the examiner’s factual findings from each primary reference (and application) are correct, we cannot sustain the rejections on appeal since we disagree with the examiner’s factual findings and conclusions of law based on the secondary references applied in every rejection on appeal, namely Cambridge and Andrews. The examiner finds that “Cambridge and Andrews each teach heating alumina in air to remove chlorine from the alumina (cols. 3 and 7; and col. 7, respectively).” Answer, page 3 (see also the Answer, each of pages 4-10). The examiner combines these references with each primary reference or application to show the obviousness of the claimed process step where halogen is removed by heating the alpha alumina powder containing the halogen in an atmosphere of air or inert gas or at reduced pressure at a specified temperature (e.g., see claims 1 and 18; Answer, page 3).
