Appeal No. 2002-2074 Application No. 09/494,965 II. The 35 U.S.C. § 103(a) rejection of claims 1, 54, 62 and 63 as being unpatentable over Garrett in view of Wood Garrett discloses a grenade launcher comprising a pressure cylinder 3, a grenade barrel 5 coaxial with the pressure cylinder, a piston 9 in the pressure cylinder, a projector plate 10 in the grenade barrel, a piston rod 8 connecting the piston and projector plate, a cartridge 18, and a firing mechanism (see Figure 4) for exploding the cartridge. The expanding gases generated by the explosion flow into the pressure cylinder and act on the piston, piston rod and projector plate to discharge a grenade loaded in the grenade barrel. As conceded by the examiner (see pages 6 and 7 in the answer), Garrett does not respond to the limitations in independent device claims 1 and 62 requiring a chamber, in which a charge of a compressed fluid is developed, selectively coupled in fluid communication with the inner space of the barrel so that the charge of compressed fluid is selectively released into the inner space of the barrel, or the corresponding limitations in independent method claims 54 and 63 requiring the steps of providing a charge of compressed fluid and rapidly releasing the charge into the tubular member. To overcome this deficiency, the examiner turns to Wood. 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
