The topline is located at the upper portion of the club head and the sole is located at the lower portion of the club head opposite the topline. The slot is located in the sole. Figure 5 shows an embodiment wherein the slot has a non-uniform height and a variable length. Figure 6 shows the slot having a width. Hunt does not disclose an insert placed in the slot. Cissel disclose a club head having a slot therein wherein an insert is place within the slot (See Figures 1-5). One having ordinary skill in the art would have found it obvious to have an insert within the slot, as taught by Cissel, in order to reduce the vibration of the impact of the club head with a golf ball. Regarding claim 2, Cissel discloses the insert having a main body with a proximal end portion, distal end portion, and a length measured from the proximal end portion to the distal end portion. A centerline along the length of the insert. Based on the profile of the slot of Hunt, the insert taught by Cissel would have a non-uniform height of the insert is along the centerline. Regarding claim 3, Hunt discloses the distal edge of the slot passing into the toe portion but does not disclose the slot curving away from the striking face. Cissel discloses in Figure 4 a slot having a chevron or V-shape receiving an insert. Cissel also notes that the angles of the walls can vary so long as the insert extends across a major portion of the impact area (See Column 2, lines 34-41). The applicant does not disclose why the slot curving away from the striking face is critical in order to attain the invention. The applicant further asserts in paragraph 0043 that the slot can have other shapes. Based on the assertion, one having ordinary skill in the art would have found the shape of the slot to be an obvious choice of design as it does not provide any new or unexpected result from that of Cissel. Regarding claim 4, Applicant does not disclose why the radius of curvature of the curving slot is critical in order to attain the invention. This is evident by paragraph 0077 of the instant application. Hunt discloses a slot having a length and Cissel discloses the slot of a length that allows the insert to occupy a majority of the impact area wherein the slot can approach or withdraw from the striking face. Based on the above, one having ordinary skill in the art would have found the radius of the slot to be an obvious choice of design as it does not provide any new or unexpected result from that of Cissel. Regarding claim 5, Applicant does not disclose why the distal edge height of the curving slot is critical in order to attain the invention. This is evident by paragraph 0078 of the instant application. Hunt discloses a slot having a height and Cissel discloses the slot of a height that allows the insert to occupy a majority of the impact area wherein the slot can approach or withdraw from the striking face. Based on the above, one having ordinary skill in the art would have found the distal edge height of the slot to be an obvious choice of design as it does not provide any new or unexpected result from that of Cissel. Regarding claim 6, Applicant does not disclose why the central height of the insert is critical in order to attain the invention. This is evident by paragraph 0082 of the instant application. Cissel discloses the insert of a uniform height that allows the insert to occupy a majority of the impact area wherein the slot can approach or withdraw from the striking face. Based on the above, one having ordinary skill in the art would have found the central height of the insert to be an obvious choice of design as it does not provide any new or unexpected result from that of Hunt and Cissel. Regarding claim 7, see the above regarding claim 6. Regarding claim 8, see the above regarding claims 1, 5, and 6.

Cissel discloses the insert of a uniform height that allows the insert to occupy a majority of the impact area wherein the insert can approach or withdraw from the striking face. Applicant further notes that the height of the insert can be uniform as evident by 0045. There is no assertion that the two profile perform differently; therefore, based on the above, one having ordinary skill in the art would have found the proximal end and central portion heights of the insert to be an obvious choice of design as it does not provide any new or unexpected result from that of Hunt and Cissel.
