Abstract
Abstract A golf ball has alternating rough and smooth bands formed in its outer surface and the rough bands are aligned parallel to the ground when the ball is teed up. The rough bands are formed to completely trip the boundary layer of air flow around the ball in order to generate forces which counteract the forces generated by the smooth bands when the golf ball rotates about certain axes of rotation so as to control the path of the golf ball during its flight. The rough bands are formed in a plurality of spaced depressions in the outer surface of the golf ball.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
87 words
A golf ball in the form of a spherical body having an outer surface, said golf ball comprising: a plurality of parallel rough bands and a plurality of parallel alternating smooth bands disposed on said surface, said rough bands being formed to completely trip the boundary layer of air flow around said rough bands so as to cancel the forces generated by said smooth bands when said golf ball rotates about predetermined axes of rotation to thereby control the path of said golf ball during its flight.
Claim 2
Dependent Claim
87 words
A golf ball in the form of a spherical body having an outer surface, said golf ball comprising: a plurality of parallel rough bands and a plurality of parallel alternating smooth bands disposed on said surface, said rough bands being formed to completely trip the boundary layer of air flow around said rough bands so as to cancel the forces generated by said smooth bands when said golf ball rotates about predetermined axes of rotation to thereby control the path of said golf ball during its flight.
Claim 3
Dependent Claim
23 words
The golf ball of claim 1 wherein the rough bands comprise a plurality of spaced depressions in the surface of said golf ball.
Claim 4
Dependent Claim
11 words
The golf ball of claim 2 wherein the depressions are dimples.
Claim 5
Dependent Claim
17 words
The golf ball of claim 2 wherein the plurality of bands of depressions comprises three spaced bands.
Claim 6
Dependent Claim
37 words
The golf ball of claim 4 wherein one of the spaced bands of depressions is located along the circumferential centerline of said golf ball and the other bands of depressions are equidistantly spaced on opposing sides thereof.
Claim 7
Dependent Claim
30 words
The golf ball of claim 1 wherein the area bounded by the rough bands is substantially equal to the remaining smooth area on the outer surface of said golf ball.
Claim 8
Dependent Claim
30 words
The golf ball of claim 1 wherein the area bounded by the rough bands is approximately 1.2 times the remaining smooth area on the outer surface of said golf ball.
