Patent ID: 7331879

Claim:
A golf ball wherein each of the northern hemisphere and the southern hemisphere thereof has a surface comprising a pole vicinity region, an equator vicinity region, and a coordination region located between the pole vicinity region and the equator vicinity region, each of the pole vicinity region, the equator vicinity region and the coordination region having numerous dimples, the dimple pattern in the pole vicinity region including multiple units that are rotationally symmetric to each other centered on the pole point, the dimple pattern in the equator vicinity region including multiple units that are rotationally symmetric to each other centered on the pole point, a number of the units in the pole vicinity region being different from a number of the units in the equator vicinity region, the dimple pattern in the coordination region being either a pattern which cannot be comparted into multiple units that are rotationally symmetric to each other centered on the pole point, or a pattern including multiple units that are rotationally symmetric to each other centered on the pole point with a number of the units being different from the numbers of the units of the pole vicinity region and the equator vicinity region.
