Appeal No. 2004-0919 Page 2
Application No. 09/842,607
BACKGROUND
The appellants' invention relates to golf balls and, more particularly, to improved
golf balls comprising multi-layer covers which, in several embodiments, are
formed from particular combinations of ionomers and/or polyurethane based materials.
In several of the embodiments, the cover layers are also relatively thin. In other
embodiments of the appellants' invention, the balls utilize a multi-layer core
construction. The improved golf balls provide for enhanced distance and durability
properties over conventional golf balls while at the same time offering enhanced "feel"
and spin characteristics generally associated with soft balata and balata-like
covers of the prior art (specification, p. 1). A copy of the dependent claims under
appeal is set forth in the appendix to the appellants' brief. The independent claims on
appeal read as follows:
1. A golf ball comprising:
a mufti-layer core assembly including (i) a center core component, and
(ii) a solid core layer disposed about said center core component; and
a mufti-layer cover assembly including (i) an inner cover layer disposed on
said core layer, and (ii) an outer cover layer disposed on said inner cover layer,
said outer cover layer defining a plurality of dimples along an outer surface of
said outer cover layer,
wherein at least one of said inner cover layer and said outer cover layer
comprise a blend of less than 50% of a high acid ionomer and greater than 50%
of a low acid ionomer.
11. A golf ball comprising:
a multi-layer core assembly including (i) a center core component, and
(ii) a solid core layer disposed about said center core component; and
a multi-layer cover assembly including (i) an inner cover layer disposed on
said core layer, and (ii) an outer cover layer disposed on said inner cover layer,
