Appeal No. 2003-0651 Page 5
Application No. 09/348,761
Even assuming that Druyan would have suggested modification of Delans’ rolling
mill plug to provide concave and convex surfaces to provide a smooth change in speed
as the pierced shell is grasped by the rolls, the examiner has not explained, and it is not
apparent to us, how appellants’ invention as recited in claim 13 (most particularly the
limitations in paragraph d) thereof) would result. It thus follows that we cannot sustain
the examiner’s rejection of claim 13 or claim 144 which depends from claim 13.
4 We interpret claim 14 as being directed to the pilgrim rolling mill assembly of claim 13, including
both the stepped mandrel and the cooperating die means recited in claim 13, since claim 14 depends
from claim 13. Claim 14, which recites “[t]he mandrel according to claim 13,” is nevertheless deserving of
correction to clarify this inconsistency.
