Abstract: The present invention is directed to a golf club having a playing characteristic that is communicated to a player based upon a vibration damping material that is colorized and visible from outside of the club head, thereby communicating to a golfer information about the playing characteristics of the club.

Abstract: Golf club heads comprising weighted materials that can be added, removed, and moved in order to change the weight and center of gravity of the club. In some instances, the weighted material is a polymer composition comprising metal and having a specific gravity greater than about 4. Also disclosed are methods of modifying the center of gravity of a golf club head and methods of manufacturing golf club heads.

Abstract: A golf club head having a low-density interchangeable insert located in a top portion thereof. The interchangeable insert may be only in the top line of the club head or extend from the heel around the toe and optionally be visible from above when the club is at address. The interchangeable insert may extend through a hosel and optionally be visible on a heel-side surface. The interchangeable insert may be mounted on a back surface of a striking face, and may extend a distance down the back surface. The interchangeable insert may extend into, and provide part of, a golf ball striking face.

Abstract: The invention provides methods of making a component for a golf club by shaping a workpiece by a first process and also shaping the workpiece by a second process that includes electrical discharge machining. A first process such as forging or casting can shape the gross morphology of the workpiece and material can be removed by the second process to form desired features or textures. In certain aspects, the invention provides a golf club head with a club head body having a face, a sole, a toe, a heel, and a hosel extending upwards from a heel-side of the club head body when the club head is at address. A part of the club head body is formed by the first process, with material having been removed from the part by the second process.

Abstract: The invention relates to golf clubs, more particularly to mechanisms for fastening accessories to clubs. The invention provides a golf club configured to house an electronic device such as an RFID tag within a recess within the grip, thereby protecting the device from the stress, shock, and exposure that arises when a golf club is used.

Abstract: The invention relates to devices, systems, and methods for fitting golf clubs. A golf club set is selected from among many golf clubs. A golfer can give information about an existing club set or hitting abilities. Systems of the invention use that information to identify a yardage gap to be covered by clubs and a number of clubs to span that yardage gap. The system can determine one or more yardage for each of the number of clubs and then propose a specific club for each yardage.

Abstract: The invention provides a golf club head that includes a weight adjustment system inside of the club head. Preferably, when the club is played, no part of the adjustment system is directly accessible or exposed to an exterior of the club. The club head may include a panel that opens or is removable, or the club head may be disassembled to provide access to the internal weight adjustment system. A weight adjustment system generally includes at least one mechanism by which a mass distribution of the golf club head can be changed.

Abstract: A golf club can include a shaft and club head. The club can have a selected length to weight ratio based on the length of the shaft and the overall weight of the club. The club head can include one or more areas with selective removal of weight to lighten the club head and/or move weight around in the club head.

Abstract: The present invention is a golf ball that has a coefficient of restitution at 143 feet per second that is greater than 0.8015, and an USGA initial velocity less than 255.0 feet per second. The golf ball is preferably a solid three-piece golf ball with a thermosetting polyurethane cover, an ionomer blend intermediate layer and a polybutadiene core.

Abstract: The present invention is a golf ball that has a coefficient of restitution that is greater than 0.8015 at 143 feet per second, and an USGA initial velocity less than 255.0 feet per second. The golf ball has a solid three-piece golf ball with a polybutadiene core, an ionomer blend intermediate layer, and a thermosetting polyurethane cover, with an aerodynamic surface geometry. The golf ball has an innersphere with a plurality of lattice members interconnected to form a plurality of polygons. Each of the lattice members has apex, such that the golf ball conforms with the USGA's golf ball diameter requirement of 1.680 inches.
