Appeal 2007-3258
Application 10/916,195
1 Katsuki Fig. 2 shows an inner liner 3 formed on the inner periphery of
2 carcass layer 2 inside of the tire. Side wall 4 is disposed on the outer
3 periphery of carcass layer 2. Col. 6:9-13.
4 Fig. 3 is an enlarged sectional view of portion X of Fig. 2.
5 Inner liner 3 comprises a laminated film made up of gas barrier layer
6 A and adhesive layers B. The adhesive layer B is made of a modified
7 polyolefin resin or the like and is laminated on at least one surface of gas
8 barrier layer A. Col. 6:16-20.
9 Gas barrier layer A can be formed from a polyester resin. Col. 6:22.
10 Among the polyester resins which are said to be useful are
11 polybutylene terephthalate-polytetramethylene oxide glycol block
12 copolymers. Col. 3:22-24.
13 The Examiner found that Katsuki differs from the claimed invention
14 in that Katsuki "does not expressly teach the specific polyester copolymer of
15 the claimed invention." Examiner's Answer, page 4.
16 Cahill
17 Cahill's invention is directed to oxygen barrier materials of the active
18 oxygen scavenger type. Col. 1:9-11.
19 The principal emphasis of Cahill is to find an oxygen barrier layer
20 which can be used in bottles and packaging. Col. 1:11-12.
21 With reference to Cahill Fig. 1, there is shown a cross sectional view
22 of an oxygen scavenging bottle wall and film construction. Col. 6:36-37.
