Appeal No. 2002-0080 Page 2
Application No. 09/170,216
BACKGROUND
Appellants’ invention relates to a three-piece golf ball.
According to appellants, “the ball is improved such that it may
receive an appropriately increased spin rate upon approach shots.
This leads to improved control, and a relatively low spin rate
upon driver shots, which leads to an increased distance.” See
page 3 of appellants’ specification. An understanding of the
invention can be derived from a reading of exemplary claim 1,
which is reproduced below.
1. A three piece solid golf ball comprising; a single solid
core and a cover of two-layer structure consisting of an
inner layer and an outer layer, characterized in that
the single solid core has a deflection of 3 to 7mm
under an applied load of 100kg,
the cover inner layer has a Shore D hardness of 25 of
58 and a thickness of 0.5 to 1.4mm,
the cover outer layer has a Shore D hardness of 30 to
57 and a thickness of 1.2 to 2.3mm, and
the ratio of the thickness of the cover outer layer to
the thickness of the cover inner layer is from 1.4/1 to
4.6/1.
The sole prior art reference of record relied upon by the
examiner in rejecting the appealed claims is:
Yamagishi et al. (Yamagishi) 5,688,595 Nov. 18, 1997
(filed June 13, 1996)
Claims 1-6 stand rejected under 35 U.S.C. § 102(e) as being
anticipated by Yamagishi.
