A Big Week for Golf Ball Patents

Five patents directed to golf ball technology issued on April 10, 2007. They include some fascinating reading regarding dimple geometry, layout, and aerodynamics. The patents include:

USPN 7,202,303 to Acushnet “Golf Ball Layers Formed of Polyurethane-Based and Polyurea-Based Compositions Incorporating Block Copolymers”

USPN 7,201,674 to SRI Sports “Golf Ball”

USPN 7,201,672 and USPN 7,201,671 to Bridgestone Sports both titled “Multi-Piece Solid Golf Ball”

USPN 7,201,670 to Mizuno titled “Golf Ball and Mold for Manufacturing Core Thereof”

The 7,201,670 patent is particularly interesting. It is directed to a uniquely shaped solid core, seen below, that produces high ball resilience and a soft feel at impact. Check out the following drawings from the patent.

Frankly, I didn’t even know that Mizuno produced golf balls. In fact, after reviewing Mizuno’s website I am not sure that they do produce golf balls. It is an interesting golf ball core design nonetheless.
