  • Golf ball having indentations in a lattice structure
    Patent number: 10814178
    Abstract: A golf ball (20) approaching zero land area is disclosed herein with a plurality of indentations positioned on the lattices of a plurality of multi-faceted polygons. The golf ball (20) has an innersphere with a plurality of lattice members (40). Each of the plurality of lattice members (40) has an apex and the golf ball (20) of the present invention conforms with the 1.68 inches requirement for USGA-approved golf balls.
