Patent number: 8216082Abstract: Embodiments of a putter-type golf club head with an increased moment of inertia about the X axis (MOIXX) and an increased moment of inertia about the Z axis (MOIZZ) are disclosed. Generally, the MOIZZ is increased by designing the putter such that the center of gravity (CG) of the putter head is located at or behind the geometric center of the putter head. Additionally, the mass of the putter head is concentrated at the outer edges of the putter head. To accomplish this, the ratio of the width of the front of the putter head to the width of the rear of the putter head is no greater than 0.55:1. The MOIXX is further increased by locating the CG relatively close to the bottom of the putter head.Type: GrantFiled: November 21, 2011Date of Patent: July 10, 2012Assignee: Taylor Made Golf Company, Inc.Inventors: Marni D.

Patent number: 7625298Abstract: This invention, in contrast to other golf club head inventions, presents an entirely new concept in the formulation of golf club heads. Wherein this invention utilizes the scientific properties of the spherical weight, resulting in substantial improvements in the functioning of the golf club heads and the corresponding improvements in the golf swing. A spherical weight is disposed in golf club heads, as specified, employing the scientific properties of the sphere, to develop an “in line momentum”. This results in a responsive control and an easier executed golf swing. The conventional golf club, actually, is made like a small paddle with an upright handle at one end. Whereas, the golf club, of this invention, because of its specifications, embodies the weight of the club head, the spherical weight, and the club shaft, substantially, all in one line, producing a superior functioning golf club.Type: GrantFiled: August 14, 2007Date of Patent: December 1, 2009Inventor: John Emmanuel Bennett
