Application No. 09/456,273
rubber composition capable of providing a tire tread having a good balance between the
rolling resistance and the coefficient of sliding friction on wet road surfaces.” See column
1, lines 6-11. The balance of Iwama is directed exclusively to tire treads. See column 1,
lines 19-27, column 3, lines 26-35, column 5, lines 56-63, column 7, lines 37-43, and
column 12, line 63 to column 13, line 23. Furthermore, we find that the Examples are
directed to compositions wherein Tire Performance is measured. See the Tables in
columns 7-12. Significantly, there is no teaching or suggestion that the entire tire is
formulated from the tire composition disclosed by Iwama. Moreover, there is no
suggestion that the tire sidewall or a veneer thereof is formulated from the composition
disclosed by Iwama.
For the foregoing reasons, we determine that the examiner has not established a
prima facie case of obviousness in view of the references of record. Accordingly, the
rejection is reversed.
