Appeal 2007-1181 Application 10/513,879 present in the air that could be detrimental to the reagents held within the package. (Answer 4). Appellant maintains that the two reagents within the Guadagno package are separated and not mixed until the packet is burst by the user, who at the same time tears open the package to expose to air the wetted pad holding the mixed reagents. Appellant thus argues that the Examiner has not established a prima facie case of obviousness because Guadagno fails to disclose or suggest “air evacuation of the sealed package holding premixed reagents on the absorbent material.” (Reply Br. 2). Appellant’s argument is not persuasive. Contrary to Appellant’s contention, we find that the limitation of a “packet including a sheet of absorbent material impregnated with a liquid solution that reacts with feces to produce a color change when blood is present” is clearly taught by Guadagno’s disclosure that the internal seal is ruptured and the reagents mixed within the sheet of absorbent material prior to opening the packet. Based on Gaudagno’s instruction, the user opens the sealed package only after the reagents are mixed therein. (Finding of Fact 4). Regardless of whether the sealed package is opened within seconds, minutes, or hours of rupturing the internal seal (see Reply Br. 1-2), the claim limitation is still met (Answer 6). In addition, Appellant’s argument fails to address the Examiner’s finding that it would have been obvious to one of ordinary skill in the art at the time of the invention to evacuate air in Guadagno’s package upon sealing the layers of the package together. Accordingly, the rejection of claims 14 and 15 as unpatentable over Guadagno is affirmed. 5Page: Previous 1 2 3 4 5 6 7 Next
