Appeal No. 2004-0643 Application No. 09/682,211 The appellants argue that their direct delivery of radiation through a capillary tube to the affected site reduces the required radiation dose and that, therefore, a portable radiation generator can be used (brief, page 6). Because, like the appellants, Vali delivers radiation directly to the affected site using a hollow fiber (col. 6, lines 38-46), Vali’s required radiation dose likewise would be relatively small and, therefore, a portable radiation generator would be suitable. For the above reasons we conclude that the appellants’ claimed invention would have been obvious to one of ordinary skill in the art within the meaning of 35 U.S.C. § 103. DECISION The rejection of claims 1, 4, 4, 5, 8-11, 13-15 and 18-23 under 35 U.S.C. § 103 over Vali is affirmed. 5Page: Previous 1 2 3 4 5 6 7 NextLast modified: November 3, 2007
