Appeal No. 2003-1379 Application No. 09/769,334 motivated by a reasonable expectation of successfully improving the safety of the aircraft during its flight2. The appellant appears to argue that the open cell polyurethane foam taught in Allen is not capable of carrying out the claimed functional limitation relating to controlled deformation as recited in claims 1, 5 and 8.3 See the Brief, pages 6 and 8. According to the appellant (Id.), “[t]he core [open cell polyurethane foam] is said to have ‘an approximate 97 percent void’ and thus it appears that the core would be of very limited value as an energy absorbing structure.” We are not persuaded by the appellant’s argument. First, we cannot distinguish the open cell polyurethane foam taught by Allen from the claimed open cell foam. Compare claims 1, 5 and 8 with the Allen disclosure mentioned above. The open cell polyurethane structure taught by Allen, like the claimed open cell foam, is said to be useful for absorbing physical energy as 2 As acknowledged by the appellant at page 6 of the Brief, the fuel is pumped into the fuel tanks (60) of Beuck’s aircraft during its flight. 3 Claim 9, the broadest independent claim in the application, does not recite the functional limitation in question. 5Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
