Appeal No. 1998-2791 Page 7 Application No. 08/422,676 The examiner recognizes that Whyte differs from the invention recited in claim 28 in that it lacks at least "a breakable barrier" separating the gas evolving material (24) from the activator material (Paper No. 15, page 3), but asserts that [t]o employ a liquid impervious breakable packet containing the liquid, i.e. and thus necessarily a predetermined quantity or amount thereof, inside a gas permeable envelope both of which are inside a gas impermeable inflatable component as taught by Lieberman and Kato on the Whyte device would be obvious to one of ordinary skill in the art in view of the recognition that such a feature would provide a self inflating structure which is simplified in structure, economically efficient and/or reliably inflated while still providing the ability of individual inflation at the point of use at the time of need and the desirability of such in any self inflating device and/or the Whyte device [Paper No. 15, page 4]. The test for obviousness is what the combined teachings of the references would have suggested to one of ordinary skill in the art. See In re Young, 927 F.2d 588, 591, 18 USPQ2d 1089, 1091 (Fed. Cir. 1991) and In re Keller, 642 F.2d 413, 425, 208 USPQ 871, 881 (CCPA 1981). Indeed, a prima facie case of obviousness is established where the reference teachings would appear to be sufficient for one of ordinaryPage: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
