Michael J Sullivan, Michael D Jordan, Derek A Ladd: Low deformation golf ball. Acushnet Company, Mandi B Milbank, October 24, 2006: US07125345 (85 worldwide citation)

A golf ball comprising an innermost core, an outer core, and a cover is disclosed. At least a layer of the golf ball is made from a low compression, high coefficient of restitution material, and is being supported by a low deformation, high compression layer. The resulting golf ball has high coeffic ...

Michael J Sullivan, Derek A Ladd, Edmund A Hebert: Foam-core golf balls. Acushnet Company, Mandi B Milbank, November 18, 2008: US07452291 (70 worldwide citation)

A golf ball with a controlled moment of inertia and controlled spin rate is disclosed. The increase in moment of inertia is preferably accomplished by a reduction in the specific gravity or weight of the core, e.g., by foaming. Preferably, this reduction is less than about 15% in specific gravity or ...

Michael J Sullivan, Derek A Ladd, Christopher Cavallaro: Multi-layer golf ball with a foamed intermediate layer. Acushnet Company, Mandi B Milbank, February 7, 2006: US06995191 (38 worldwide citation)

A golf ball with relatively rigid inner core and soft intermediate layer is disclosed. The rigid inner core maintains the balls' high coefficient of restitution at high impact speeds, while the soft intermediate layer provides better feel for greenside play. The intermediate layer can be made from a ...
