Abstract:
A golf club incorporating a stress reducing feature, including an aperture, located at least partially on the sole of the club head. The location and size of the stress reducing feature and aperture, and their relationship to one another, play a significant role in selectively improving the performance of the golf club.

Claim (Index 18):
A hollow golf club having a stress reducing feature with aperture comprising:\n (A) a shaft ( 200 ) having a proximal end ( 210 ) and a distal end ( 220 ); (B) a grip ( 300 ) attached to the shaft proximal end ( 210 ); and (C) a golf club head ( 400 ) attached to the shaft distal end ( 220 ) and having:\n (i) a face ( 500 ) positioned at a front portion ( 402 ) of the golf club head ( 400 ) where the golf club head ( 400 ) impacts a golf ball, and wherein the face ( 400 ) includes a top edge height (TEH) and a lower edge height (LEH), and the face ( 400 ) has a face thickness that varies from a minimum thickness of at least 0.050\u2033 to a maximum thickness; \n (ii) a sole ( 700 ) positioned at a bottom portion of the golf club head ( 400 ); \n (iii) a crown ( 600 ) positioned at a top portion of the golf club head ( 400 ); \n (iv) a skirt ( 800 ) positioned around a portion of a periphery of the golf club head ( 400 ) between the sole ( 700 ) and the crown ( 600 ), wherein the face ( 500 ), sole ( 700 ), crown ( 600 ), and skirt ( 800 ) define an outer shell that further defines a head volume, and wherein the golf club head ( 400 ) has a rear portion ( 404 ) opposite the face ( 500 ); \n (v) a bore having a center that defines a shaft axis (SA) which intersects with a horizontal ground plane (GP) to define an origin point, wherein the bore is located at a heel side ( 406 ) of the golf club head ( 400 ) and receives the shaft distal end ( 220 ) for attachment to the golf club head ( 400 ), and wherein a toe side ( 408 ) of the golf club head ( 400 ) is located opposite of the heel side ( 406 ); \n (vi) a center of gravity (CG) of the golf club head ( 400 ) located:\n (a) vertically toward the crown ( 600 ) of the golf club head ( 400 ) from the origin point a distance Ycg; \n (b) horizontally from the origin point toward the toe side ( 408 ) of the golf club head ( 400 ) a distance Xcg that is generally parallel to the face ( 500 ) and the ground plane (GP); and \n (c) a distance Zcg from the origin toward the rear portion ( 404 ) in a direction generally orthogonal to the vertical direction used to measure Ycg and generally orthogonal to the horizontal direction used to measure Xcg; \n \n (vii) a stress reducing feature ( 1000 ) including a sole located SRF ( 1300 ) located at least partially on the sole ( 700 ), wherein:\n (a) the sole located SRF ( 1300 ) has a SSRF length ( 1310 ) between a SSRF toe-most point ( 1312 ) and a SSRF heel-most point ( 1316 ), a SSRF leading edge ( 1320 ) having a SSRF leading edge offset ( 1322 ), a SSRF trailing edge ( 1330 ), a SSRF volume, a SSRF width ( 1340 ), and a SSRF depth ( 1350 ), wherein the sole located SRF ( 1300 ) has at least one of (a) a portion of the SSRF width ( 1340 ) is at least ten percent of the Zcg distance, and (b) a portion of the SSRF depth ( 1350 ) is at least ten percent of the Ycg distance; and \n (b) the sole located SRF ( 1300 ) has a SSRF aperture ( 1400 ) recessed from the sole ( 700 ) and extending through the outer shell, wherein the SSRF aperture ( 1400 ) has a SSRF aperture length ( 1410 ) between a SSRF aperture toe-most point ( 1412 ) and a SSRF aperture heel-most point ( 1416 ), and a SSRF aperture width ( 1440 ) that is less than the maximum face thickness, wherein the SSRF aperture length ( 1410 ) is at least fifty percent of the Xcg distance; and \n (c) the golf club head ( 400 ) has a characteristic time of at least 220 microseconds.
