Patent ID: 8657706

Claim:
A golf ball having a plurality of dimples formed on its outer surface, the outer surface of the golf ball being divided into plural areas, a first group of areas containing a plurality of first dimples and a second group of areas containing a plurality of second dimples, each area of the second group abutting one or more areas of the first group, the first and second groups of areas and dimple shapes and dimensions being configured such that the golf ball is spherically symmetrical as defined by the United States Golf Association (USGA) Symmetry Rules, and such that the golf ball exhibits a drag coefficient (CD) below about 0.255 at a Reynolds Number (Re) of about 165,000 and at a spin rate in the range of about 3,400 rpm to about 3,550 rpm and in a range from about 0.295 to 0.330at a RE in a range of about 80,000 to 100,000 and at a spin rate in a range of about 2,900 rpm to about 3,320 rpm, wherein the dimple radius of each dimple in the first areas is in the range from about 0.05 to about 0.06 inches, wherein the dimple chord depth in the first areas is in the range from about 0.0075 to about 0.01 inches, and wherein the dimple chord depth in the second areas is in the range from about 0.0035 to about 0.008 inches.
