rubber (12) to prevent a portion (5b) of the packing sheet from
being bonded to the inner liner rubber when the tire is vulcanized
(pages 6, 8-10, 12, 13).
Kuan discloses forming a pocket which is attached to the
sidewall of a tire and contains a lubricant (abstract). The
pocket is formed by Harrington’s method (Harrington, col. 2, lines
53-68) wherein a strip of release material which conforms to the
width and length of the pocket is placed between inner liners
before the tire is vulcanized (Kuan, col. 2, lines 17-39).
Case discloses a method for preventing a tire tread inner
layer (3) from adhering to an inner tube (6) during vulcanization
by placing between the tread inner layer and the tube a fabric
which will not bond to the inner layer during vulcanization
(page 1, lines 57-66).
The teachings of Honda, Kuan, Harrington and Case would have
fairly suggested, to one of ordinary skill in the art, placing an
anti-adhesive sheet on the lower surface of O’Brien’s indented
tire segment around its circumference prior to vulcanization so
that the surface under the anti-adhesive sheet does not bond to
the rubber above the sheet during vulcanization and that
therefore, the desired chamber is formed.
The appellants argue that O’Brien is a parent of the present
application and is not prior art (brief, pages 6-8; reply brief,
