20150343269 | GOLF BALL WITH GROUND DOWN MEDIAL LAYER - A golf ball includes a core, one or more inlaid portions formed into the core, and a second layer disposed radially outward of both the core and the one or more inlaid portions. The core and the one or more inlaid portions cooperate to define a continuous spherical surface, and the core and the second layer cooperate to surround each of the one or more inlaid portions. The one or more inlaid portions are formed by over-molding the core, and then removing the over-molded material back to at least the outer surface of the core. | 12-03-2015 |
