Appeal 2007-0871 Application 10/967,816 equipping a user with a buoyancy compensator comprising a controller, tank containing at least one gas, and an expander, the tank being operably connected to deliver the at least one gas to the expander under the control of the controller; providing a hydrofoil; connecting the hydrofoil to the user; positioning the user and hydrofoil underwater at a selected depth; and operating the controller to alternate the overall buoyancy of the user and hydrofoil between levels above and below neutral buoyancy, the controller releasing the at least one gas into the ambient water to decrease the overall buoyancy. The Examiner relies upon the following references as evidence of obviousness: Schuler US 3,898,705 Aug. 12, 1975 McLane US 3,947,906 Apr. 6, 1976 Appellant's claimed invention is directed to a method of underwater propulsion of an individual using a buoyancy compensator that comprises a controller, a tank containing at least one gas, and an expander. The tank is operably connected to deliver the gas to the expander to alter the overall buoyancy of the individual in the water. Gas is released to the ambient water to decrease the overall buoyancy. Appealed claims 1-30 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over McLane in view of Schuler. Appellant has not set forth separate arguments for any particular claim on appeal. Accordingly, all of the appealed claims stand or fall together with claim 1. 2Page: Previous 1 2 3 4 5 Next
