Appeal No. 1999-0455 Application 08/635,483 artisan to select 40-44 gram wall tubing for a stethoscope as claimed. Such evidence is lacking on this record. Because the examiner has failed to establish a prima facie case of the obviousness of the claimed invention, we do not sustain the examiner’s rejection of the appealed claims. Therefore, the decision of the examiner rejecting claims 1-3 and 5 is reversed. REVERSED ) JERRY SMITH ) Administrative Patent Judge ) ) ) ) BOARD OF PATENT STUART S.
