ordinary skill in the art towards the claimed proportions and
lengths of the metal tip sections for given total shaft lengths.
With respect to progressively decreasing club head lofts
(angles) in relation to decreasing the lengths of the metal tip
sections of shafts (i.e., increasing total shaft lengths) as
recited in claim 10, we concur with the examiner that one of
ordinary skill in the art would have been led to progressively
decrease club head lofts as the lengths of metal tip sections of
the shafts are decreasing as suggested by Dillard, Whitaker,
Pompa and Bayliss. Bayliss shows conventional club head face
lofts (angles), like the metal tip section lengths, are inversely
related to total shaft lengths (a longer shaft, a smaller club
face angle and greater flexibility (shorter metal tip section)
are all associated with a longer distance)). See Figure 1. We
also note that Whitaker indicates that the determination of
desired shaft flexibilities, overall shaft lengths and club head
face angle (loft) for given ball striking range potentials is
well within the ambit of one of ordinary skill in the art.
