top of the grass and if a maximum distance shot is required
(id. at 44-47). Under such circumstances, Pfau describes the
position of the ball as being about ½ inch above the grass
root top level G (id. at 44-49). Thus, to compensate for the
higher position of the ball, Pfau teaches that the length of
the #2 wood must be about 3/16 of an inch shorter that the #3,
#4 or #5 wood (id. at 50-54). Finally, it is assumed that the
driver or #1 wood is used almost exclusively for tee shots in
which the ball 32 is elevated about one inch above the grass
root top level G (id. at 55-58). Therefore, in order to
maintain a uniform distance D between the ball and the
golfer’s feet, the driver must have a length C about 3/8 of an
inch shorter than the #2 wood and about 9/16 of an inch
shorter than the #3, #4 or #5 wood (id. at 58-63).
Pfau also teaches that each club would be weighted in
accordance with well-known methods so that each club would
have the same swing weight. To achieve this, the driver
(Pfau’s shortest club of the set) would be the heaviest with
the #2 wood slightly lighter, and so on (col. 2, line 70
through col. 3, line 4). In other words, Pfau teaches that as
a club is shortened, weight has to be added in order to
