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.
