Golf ball
First Claim
1. A golf ball in the shape of a sphere having a multiplicity of spaced apart dimples distributed generally uniformally over the outer surface thereof and having a continuous spherical surface between said dimples, the invention comprising:
- a. at least one undimpled patch on the outer surface of the ball for use as a smooth putter-contacting surface;
b. the extent of the undimpled patch ranging from a first minimum size and shape corresponding to the undimpled area achieved by removing four of the dimples on the ball, said four dimples being arranged generally in the pattern of a square;
c. a second maximum area corresponding to the smooth undimpled area achieved by removing sixteen of the dimples on the ball, said sixteen dimples being arranged generally in the shape of a square, whereby the golf ball exhibits more accurate directional control during putting without significantly detracting from hang time of the ball in flight.

Abstract
A golf ball is shown with an outer surface that is substantially covered with a plurality of spaced dimples that give the ball a suitable long and predictable flight pattern for wood or iron shots due to imparting an increased lift to the ball when the ball has a backspin. An undimpled patch is formed on the outer surface for use as a smooth putter-contacting surface. The size of the undimpled patch is chosen to achieve the desired putting accuracy objective without detracting from the increased "hang" time of the flight of the ball. The center of the undimpled patch is substantially spaced between about 90° and 100° from the center of the imprint of the brand name of the ball manufacturer, so the ball may be positioned for putting with the brand name indicia located at the top of the ball, and the location of the undimpled patch being easily discernible from above by the golfer as he stands over the ball and prepares to putt.
