Appeal No. 1997-3288 Application 08/529,303 should be subtracted from the amount in inventory in a method of tracking chemical usage. In fact, since the amount of material removed from the tank will be either used or disposed of, the amount sensed at the disposal points would not be subtracted; this is a second difference. The Examiner does not address these differences and, thus, has failed to establish a prima facie case of obviousness. The rejection of claims 2 and 3 is reversed. REVERSED STANLEY M.
