Multi-layer golf ball having velocity gradient from slower center to faster cover
First Claim
1. A multi-layer golf ball comprising a center, a cover layer, and at least two intermediate layers between the center and the cover layer, wherein each subassembly of the golf ball has a combined coefficient of restitution value that is less than the combined coefficient of restitution of said subassembly plus the next outer layer by a value of at least 0.003, wherein the subassembly comprises at least the center.

Abstract
The present invention is directed to multi-layer golf balls having a center, a cover layer, and at least one intermediate layer between the core and the cover layer. The center, the at least one intermediate layer and the cover are constructed to have different initial velocities and COR such that the gradients of initial velocities and COR progress from a slower center to a faster cover.
