Appeal No. 1998-2424 Application 08/515,269 obvious. Boston shows an impermeable sheath that can be folded or unrolled to be dispensed and placed in a container, the open end of the sheath coinciding with the open end of the container. Appellant argues that the sheath is not bacteriologically impermeable. However, Boston is clearly intended to keep the interior of the sheath sanitary and sterile. Therefore, we regard bacteriological impermeability as an inherently property of the sheath of Boston. For this reason, we will affirm the 35 U.S.C. § 103 rejection of claim 22 based on the Boston reference. 8Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
