Appeal No. 2004-1197 Application No. 10/041,430 Saitoh. Thus, considering the only prior art before us, the obviousness rejection on appeal cannot be sustained. REMAND TO THE EXAMINER We remand this application to the examiner for the following reason. It does not appear in the record that any known methane detectors that give off audible warnings have been considered. The examiner should assess broad claim 10, for example, in light of known methane detectors. In summary, this panel of the Board has not sustained the obviousness rejection on appeal and has remanded the application to the examiner for the reason given above. 5Page: Previous 1 2 3 4 5 6 7 NextLast modified: November 3, 2007
