The Golfball Index (UPDATED: April 2012)

See previous index for January, February, and March 2012.

The Golfball Index maintained its recent  lacklustre performance during April 2012. As in the previous month, there were only 7 new US golfball patents.

• Thick inner cover multi-layer golf ball

• Three-layer-core golf ball having highly-neutralized polymer outer core layer

• Multi-piece golf ball comprising low hardness gradient core

• High performance golf ball having a reduced-distance

• Multi-layer core golf ball having opposing hardness gradient with steep gradient inner core layer

• Golf ball with negative hardness gradient core

• Multi-layer core golf ball

Caution with regard to forward-looking statements: Historical data should not be taken as an indicator of future performance. The Golfball Index may go down as well as up.
