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
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.
